a regional energy hub for achieving a low carbon energy transition abstract the transition to a low carbon energy economy will remain a cornerstone of national energy policies of countries committed to the climate change accord for decades to come we think that transmission investment is one key policy instrument amongst other to help with this transition we propose an enhanced role for investing in transmission capacity for inter regional trade to allow effective fuel switching among countries through a physically connected market we develop a conceptual framework of regional energy hubs and propose a cost minimization model in support of a transmission investment strategy that integrates i a key geopolitical parameter for countries that are geographically close in a region but under different political jurisdictions judged as stable and receptive to firm trading arrangements ii an economic parameter related to the fuel mix where the differences in a country s supply and demand characteristics are significant enough for allow mutual benefits to be realized through cost reduction iii an environmental parameter linked to a country s carbon intensity that could benefit from the resources of a neighboring jurisdiction with lower intensities and iv a financial parameter for each country within a region capable of attracting investment capital a connected regional energy hub offers large economic and environmental benefit for transition to a low carbon energy economy

energy security in asean a quantitative approach for sustainable energy policy abstract we investigate energy security of the association of southeast asian nations asean under the 4 a s framework the asean economic community aec agreement launched in 2015 renewed a regional focus on energy security and sustainability we employ an analytic framework to quantitatively assess progress in different categories including availability acceptability affordability and applicability key metrics include the documentation of co 2 emissions energy access measures and energy supply reserves from 2005 2010 we identify relevant energy indicators using high quality historical data from the iea and world bank we find that asean made little progress toward establishing energy security in the previous five year planning period 2005 2010 as it regressed in most categories except applicability therefore we suggest that increased development of renewable energy and energy efficiency technologies would move asean in a positive direction toward achieving energy security and sustainable energy policy goals

explaining instability in the stability and growth pact the contribution of member state power and euroskepticism to the euro crisis the stability and growth pact clearly failed to prevent the euro crisis we contend that the failure was due largely to the ability of the member states to undermine the pact s operation the european commission served as a watchdog to monitor fiscal performance the member states themselves however collectively had the ability to change the content of the reports for individual states we confirm the expectation that powerful member states had the most success in undermining the role of the commission perhaps more surprisingly we find supporting evidence for our argument that governments with euroskeptic populations behind them were also more successful in weakening the commission s warnings these results have broader theoretical implications concerning which mechanisms explain country specific outcomes under a shared rule another contribution is the creation of a new data set of european commission assessments of member state economic programs and council of minister revisions

greener more integrated and less volatile a quantile regression analysis of italian wholesale electricity prices abstract this paper provides estimates of quantile regression models of the relationship between italian day ahead electricity prices the supply of renewables and the inception of a new cable sapei linking sardinia with the italian peninsula in the 2006 2015 time window the results confirm the merit order effects detected in the existing literature both for photovoltaics and wind power more strongly in market conditions characterised by moderately low price levels and with some implied increase in volatility the new cable has apparently challenged the ability of power generating companies to extract value through price spikes has mitigated volatility and its effects have been complementary with those of renewables effects from photovoltaics are more sensitive to robustness checks differences across zonal markets are nonetheless detected

geographies of energy transition space place and the low carbon economy this paper makes a case for examining energy transition as a geographical process involving the reconfiguration of current patterns and scales of economic and social activity the paper draws on a seminar series on the geographies of energy transition security climate governance hosted by the authors between 2009 and 2011 which initiated a dialogue between energy studies and the discipline of human geography focussing on the uk government s policy for a low carbon transition the paper provides a conceptual language with which to describe and assess the geographical implications of a transition towards low carbon energy six concepts are introduced and explained location landscape territoriality spatial differentiation scaling and spatial embeddedness examples illustrate how the geographies of a future low carbon economy are not yet determined and that a range of divergent and contending potential geographical futures are in play more attention to the spaces and places that transition to a low carbon economy will produce can help better understand what living in a low carbon economy will be like it also provides a way to help evaluate the choices and pathways available

energy consumption and economic growth revisited in african countries abstract the aim of this paper is to provide new empirical evidence on the relationship between energy consumption and economic growth for 21 african countries over the period from 1970 to 2006 using recently developed panel cointegration and causality tests the countries are divided into two groups net energy importers and net energy exporters it is found that there exists a long run equilibrium relationship between energy consumption real gdp prices labor and capital for each group of countries as well as for the whole set of countries this result is robust to possible cross country dependence and still holds when allowing for multiple endogenous structural breaks which can differ among countries furthermore we find that decreasing energy consumption decreases growth and vice versa and that increasing energy consumption increases growth and vice versa and that this applies for both energy exporters and importers finally there is a marked difference in the cointegration relationship when country groups are considered

interpreting concentration indices in the secondary market for natural gas transportation the implication of pipeline residual rights abstract in 1992 the u s federal energy regulatory commission created a secondary market for natural gas transportation whereby shippers holding firm transportation capacity on interstate natural gas pipelines can compete with the pipeline in the provision of transportation services however if a shipper does not use some of its contracted firm transportation capacity the pipeline can resell that capacity as interruptible transportation that is the pipeline has residual rights with respect to firm transportation capacity contracted for by shippers we demonstrate that these residual rights can have a significant effect on the competitiveness of the secondary market for natural gas transportation a consequence of these residual rights is that the secondary market for natural gas transportation may be considerably more competitive than indicated by measures of concentration like the widely used herfindahl hirschman index

renewable energy and geopolitics a review this article reviews the literature on the geopolitics of renewable energy it finds that while the roots of this literature can be traced back to the 1970s and 1980s most of it has been published from 2010 onwards the following aggregate conclusions are extracted from the literature renewable energy has many advantages over fossil fuels for international security and peace however renewable energy is thought to exacerbate security risks and geopolitical tensions related to critical materials and cybersecurity former hydrocarbon exporters will likely be the greatest losers from the energy transition many of the reviewed publications share some weaknesses a failure to define geopolitics an unwarranted assumption that very little has been published in the field previously limited use of established forecasting scenario building or foresight methodologies a lack of recognition of the complexity of the field a lack of theorisation most authors do not distinguish between the geopolitical risks associated with different types of renewable energy and only a few distinguish clearly between the geopolitics of the transitional phase and the geopolitics of a post energy transition world a disproportionately large part of the literature is dedicated to critical materials and cybersecurity while only a small part concerns the decline of former fossil fuel powers among those publications that do discuss the decline of fossil fuels there is also an over focus on oil producers and a lack of attention to the countries that rely heavily on coal for example australia china germany indonesia poland and the united states

institutional reform and technological practice the case of electricity this article proposes a framework for categorizing possible interrelations between technological and institutional change and applies this framework to the case of the restructuring of the electricity sector it is argued that there is a need for coherence between institutions and technological practice so as to safeguard the satisfactory functioning of electricity infrastructure the identification of possible incoherences between institutions and technological practice allows for a better understanding of the potential drivers for change and the evolutionary processes of which they may be part this article attempts to elaborate the nature of this co evolution in somewhat more detail using specific levels of analysis that are exemplified in a four level model in the case of the restructuring of the electricity sector the institutional framework has changed from a public utility oriented towards a market oriented system however the technological practice remained unchanged a system oriented approach that relies on centralized planning control and operation this discrepancy between institutions and technological practice leads to significant frictions in the functioning of the electricity sector but it also offers opportunities for innovation in order to make liberalization a success it might be necessary to stimulate certain technical developments i e distributed generation and intelligent networks

elecxit the cost of bilaterally uncoupling british eu electricity trade abstract the uk s withdrawal from the european union could mean that it leaves the eu s internal energy market for electricity elecxit this paper develops methods to study the longer term consequences of this electricity market disintegration especially the end of market coupling before european electricity markets were coupled different market closing times forced traders to commit to cross border trading volumes based on anticipated market prices interconnector capacity was often under used and power sometimes flowed from high to low price areas a model of these market frictions is developed empirically verified on 2009 data before french and british market coupling and applied to estimate the costs of market uncoupling in 2030 a less efficient market and the abandonment of some planned interconnectors would raise generation costs by 700 m a year 2 compared to remaining in the internal energy market this result is sensitive to how the british and french electricity systems develop over the coming decades economic losses are four times greater 2700 m a year if france retains substantial nuclear capacity due to its low marginal costs conversely losses are reduced by two thirds if uk weakens its decarbonisation ambitions as lower carbon prices subsidise british fossil fuel generation allowing electricity prices to converge with those in france a hard elecxit would make british prices rise and french prices fall in three of our four scenarios with the opposite movements in the fourth scenario

a review on the central america electrical energy scenario abstract since the mid 1990s after the pacification of central america the region has experienced a sustained economic growth additionally the central american governments have been able to increase the population s access to electricity e g the percentage of central american population with access to electricity in 1995 and 2010 was 59 and 86 respectively the aforementioned reasons and the need to reduce electricity costs in order to remain competitive in a global economy have produced a transformation of the power scenario in central america the present paper presents a review about the power generation scenario of central america within the framework of the new regional interconnected electric system it also briefly analyzes the trends of the power generation profile with a special emphasis on the renewable energy sources as it can be inferred from the analysis presented in this paper the central american power scenario will mainly be shaped by the participation of the private sector and the development of the recently created regional electricity market additionally it is clear the willingness of all the central american countries to move away from oil fired power generation the lack of up front capital needed to develop large renewable energy projects mainly hydropower can favor the development of gas fired and or coal fired power stations nevertheless the regional electricity market may favor the viability of large power generation projects

the contested energy future of amman jordan between promises of alternative energies and a nuclear venture metropolitan authorities and local business elites are often seen as major players in the energy transition in the city such energy transitions are mostly conceived of as low carbon technologies which permit the retrofitting of urban infrastructure and the rebundling of metabolic circuits this article contests these views by highlighting the major role of non urban energy sector institutions and actors by examining the connections between technology space and energy politics and by using a relational understanding of the urban this article explores the case of amman s energy transition the growth of consumption coupled with new energy practices face a problematic supply because shifts in regional geopolitics prompted energy transition policies among which are included a green growth program and the building of a nuclear power plant at the edge of the city the article analyses the socio political assemblages that shape those policies and unravel the competing interests at stake it demonstrates the political and highly unruly nature of energy transitions

conceptualizing energy security abstract energy security 1 is one of the main targets of energy policy however the term has not been clearly defined which makes it hard to measure and difficult to balance against other policy objectives we review the multitude of definitions of energy security they can be characterized according to the sources of risk the scope of the impacts and the severity filters in the form of the speed size sustention spread singularity and sureness of impacts using a stylized case study for three european countries we illustrate how the selection of conceptual boundaries along these dimensions determines the outcome this can be avoided by more clearly separating between security of supply and other policy objectives this leads us to the definition of energy security as the continuity of energy supplies relative to demand

from micro to macro via production networks amodern economy is an intricately linked web of specialized production units each relying on the flow of inputs from their suppliers to produce their own output which in turn is routed towards other downstream units in this essay i argue that the structure of this production network is key in determining whether and how microeconomic shocks affecting only a particular firm or technology along the chain propagate throughout the economy and shape aggregate outcomes therefore understanding the structure of this production network can better inform both academics on the origins of aggregate fluctuations and policy makers on how to prepare for and recover from adverse shocks that disrupt these production chains two recent events have brought to the forefront the importance of interconnections between firms and sectors in aggregate economic performance consider first the 2011 earthquake in japan while the triple tragedy of the earthquake the ensuing tsunami and the near nuclear meltdown at fukushima surely resulted in a significant destruction of human and physical capital its effects would have been largely restricted to the affected areas were it not for the disruption of national

security independence and sustainability imprecise language and the manipulation of energy policy in the united states abstract this article examines the impact of imprecise terminology on the energy policymaking process in us focusing on the manipulation of discourse by different political economic interests seeking to sway popular opinion using the 2012 us presidential elections as a backdrop the analysis highlights the cooption of the concepts security independence and sustainability in energy debates by different and often opposing interest groups the article s first section traces the malleability of energy terminology to the vagueness of the term energy itself and notes how qualifying words like security independence and sustainability have been selectively exploited to introduce further ambiguity to an already fungible concept the second section notes that while energy is a critical and complex factor of macroeconomic production its main public visibility comes via a few partially representative numbers like gasoline prices this mismatch of broad social importance and piecemeal public understanding enables organized interests to leverage vague terminology in support of particular policy ideas the third section examines three policymaking tools 1 taxation 2 regulation and 3 technology promotion and compares these administrative instruments ultimately the article concludes that loosely defined terminology inhibits energy policy discussion and stifles meaningful public debate over and action on energy issues

the implications of brexit for the electricity sector in great britain trade offs between market integration and policy influence this paper examines the trade off between the economic gains to great britain gb from being integrated into the eu electricity market on the one hand and a loss of influence over policy and rule making on the other the aim is not to predict how this trade off will be resolved in practice but rather to lay out what is at stake on both sides of the equation since the late 2000s the electricity market in gb has become increasingly integrated with continental european markets through market coupling and increasing interconnection capacity with further integration expected up to the mid 2020s estimates of the economic benefits of this integration range up to the order of several 100 m to 1bn a year representing the economic cost of a reversal of such integration on the other hand maintaining and expanding electricity market integration would require the acceptance of electricity policies and regulations made in european institutions in which uk actors would have little if any voice an intermediate multilateral approach offering the possibility of retaining market integration with less cost in terms of influence is proposed

south asia energy security challenges and opportunities south asia has witnessed a growing imbalance between energy demand and its supply from indigenous sources resulting in increased import dependence energy endowments differ among the south asian countries however access to the significant energy resources in the neighboring countries is denied which increases the cost of energy supply and reduces energy security of the individual countries and of the region as a whole the countries in the region could benefit significantly only by strengthening the mechanism of energy trade through improved connectivity therefore greater cooperation within south asia could be one of the most effective ways to deal with this regional energy deficit and ensure energy security of the region

res and risk renewable energy s contribution to energy security a portfolio based approach abstract during the first decade of the 21st century renewable energy sources res had been gaining momentum due to environmental issues concerns about pollution and climate change have raised public awareness encouraging governments to adopt policies to preserve and protect the environment regarding energy res promotion together with energy efficiency measures has been the main policy response to address such concerns as a consequence res development during the first decade of the 21st century has been remarkable although res deployment has been mainly focused on achieving environmental goals its potential contribution to energy security went not unnoticed however it is worth noting that while the trade off between environmental goals and the use of res to accomplish them and competitiveness has been widely explored the relationship between energy security and res has received less attention both at the conceptual and energy policy levels this article tries to address such a relationship the present article focuses on renewable electricity imports as illustrated by the case of the mediterranean solar plan after introducing the energy security energy risk concept and its dimensions the article focuses on the contribution of res in terms of security of supply for a given energy mix using the portfolio theory most of the analyses of the interactions between res and energy security focus on the national level with res being mainly conceived as a substitute for fuel imports to produce electricity and reduce so called energy dependence however new transmission technologies allow the import of electricity directly from neighbouring countries far out of the range of regular electricity lines therefore this article tries to broaden the analysis of energy security to international res trade flows applying the previous discussion to the main project involving significant international green electricity trade the mediterranean solar plan

investment options and bargaining power the eurasian supply chain for natural gas we use cooperative game theory to analyze how the architecture of the pipeline network determines the power structure in the supply chain for russian gas if the assessment is narrowly focused on the abilities to obstruct flows in the existing system the main transit countries belarus and ukraine appear to be strong if investment options are accounted for however russia achieves clear dominance we show that options to bypass one of the transit countries are of little strategic importance compared to russia s direct access to its customers through the baltic sea comparing the results of our calibrated model with empirical evidence obtained from transit and import agreements we find that the shapley value explains the power of major transit countries better than the core and the nucleolus

integration of multiple national markets for electricity the case of norway and sweden during the second part of the 1990s the nordic denmark finland norway and sweden countries have created a unique multinational market for electricity this paper aims to analyse the degree of integration of the different national markets that constitute the nordic electricity market in particular the norwegian and swedish wholesale and retail electricity markets are analysed the results suggest that the wholesale markets are well integrated thus prices differ significantly only during periods with unusually high or low supply of hydropower however the retail markets are not integrated to the same degree thus retail prices and trade margins differ significantly differences in the national electricity market legislation seem to be a key factor behind these differences

the energy growth nexus reconsidered persistence and causality abstract this article applies a recent econometric framework to the analysis of the relationship between energy consumption and economic growth in the us which allows a joint study of causality and persistence we provide evidence suggesting a nonlinear relationship with a structural break in the most recent regime we find that gdp causes energy consumption and vice versa furthermore both series show persistence i e cyclical and natural components do not evolve independently thus policies oriented to the reduction of energy consumption could constrain economic growth and policy shocks can have permanent effects

speculative trading of electricity contracts in interconnected locations abstract we derive an investor s optimal trading strategy of electricity contracts traded in two locations joined by an interconnector the investor employs a price model which includes the impact of her own trades the investor s trades have a permanent impact on prices because her trading activity affects the demand of contracts in both locations additionally the investor receives prices which are worse than the quoted prices as a result of the elasticity of liquidity provision of contracts furthermore the investor is ambiguity averse so she acknowledges that her model of prices may be misspecified and considers other models when devising her trading strategy we show that as the investor s degree of ambiguity aversion increases her trading activity decreases in both locations and thus her inventory exposure also decreases finally we show that there is a range of ambiguity aversion parameters where the sharpe ratio of the trading strategy increases when ambiguity aversion increases

welfare and competition effects of electricity interconnection between ireland and great britain this study analyzes the effects of additional interconnection on welfare and competition in the irish electricity market i simulate the wholesale electricity markets of the island of ireland and great britain for 2005 i find that in order for the two markets to be integrated in 2005 additional interconnection would have to be large the amount of interconnection decreases for high costs of carbon since this causes the markets to become more similar this suggests that in the absence of strategic behavior of firms most of the gains from trade derive not from differences in size between countries but from technology differences and are strongly influenced by fuel and carbon costs social welfare increases with interconnection although at a decreasing rate as the amount of interconnection increases there are also positive effects on competition in ireland the less competitive of the two markets finally it is unlikely that private investors will pay for the optimal amount of interconnection since their returns are significantly smaller than the total social benefit of interconnection

the effect of a new power cable on energy prices volatility spillovers abstract in this paper we estimate volatility spillovers before and after the introduction of a new cable linking different electricity market zones using wholesale electricity prices for sardinia and two neighbouring italian market zones for the period 2005 2015 we focus on the effects of the sapei cable fully operational since march 2011 var garch estimates indicate that the sapei cable allowed for stronger volatility transmission towards sardinia a smaller zone and a net importer from its new neighbour the central southern zone albeit the effect was significant only off peak higher conditional correlations between zonal prices are also observed after the cable was introduced some implications are drawn about the interaction between market size export positions congestion and volatility transmission

energy security in china a quantitative analysis and policy implications abstract this study aims to examine how china s energy security has changed over 30 years of reform and the opening period it constructs a 4 as quantitative evaluation framework the availability of energy resources the applicability of technology the acceptability by society and the affordability of energy resources the quantitative results show that china s energy security was at its best during the sixth fyp period 1981 1985 but then deteriorated until it hit higher levels between 1995 and 2005 however it was still lower than the level reached during the sixth fyp period during the eleventh fyp period 2006 2010 the energy security situation deteriorated again differences in policy priority over the study period appear to affect the country s energy security status this study suggests that china needs to develop renewable energy resources on a large scale and pay more attention to emissions control to reverse the downward trend in energy security

china s supply of critical raw materials risks for europe s solar and wind industries abstract this article examines the dependence of the european union s solar and wind industries on chinese supply of five critical raw materials tellurium gallium indium and the rare earths neodymium and dysprosium based partly on interviews with experts this study reviews china s industrial policies that shape the supply of these materials abroad we also assess the short and long term strategies of the european union and european solar and wind industries to ameliorate potential supply bottlenecks while these strategies adequately address short term challenges we find they pose several long term risks such as increasing the dependence on china and hampering european competitiveness in global markets there is also divergence in the extent to which these two industries are vulnerable to supply bottlenecks and price volatility because more options are open to them european solar manufacturers are less exposed to these risks than their counterparts in the offshore wind sector

efficiency in employment based health insurance the potential for supra marginal cost pricing currently the majority if privately insured individuals in the u s are insured through their employers this has significant implications for competition and the ability qf a competitive insurance industry to assure marginal cost pricing the central barrier to competition arises when employers restrict their employees ability to select among insurance carriers several models 4 insurer proft maximization are explored which demonstrate that supra marginal cost pricing is likely to persist euen when the insurance market appears cornpetitiue

causal nexus between energy consumption and economic growth for high middle and low income countries using frequency domain analysis abstract this study aims to investigate the causal nexus between energy consumption and economic growth for 119 countries from all over the world having at least 30 years of available data on candidate variables including 30 high income oecd 13 high income non oecd 65 middle income and 11 low income countries the study employs granger causality in the frequency domain context for empirical analysis which allows one to examine the causal nexus over different frequencies and thus provides relatively a better picture of the causal nexus between the candidate variables in particular we examine the temporary short run as well as at permanent long run causal nexus between energy consumption and economic growth the empirical results suggest that 18 countries including 5 high income oecd 2 high income non oecd 10 middle income and 1 low income confirm the existence of feedback hypothesis 25 countries including 4 high income oecd 3 high income non oecd 14 middle income and 4 low income confirm growth hypothesis out of total 119 countries similarly 40 countries including 6 high income oecd 6 high income non oecd 27 middle income and 1 low income suggest conservation hypothesis while 36 countries comprising of 15 high income oecd 2 high income non oecd 14 middle income and 5 low income hold neutrality hypothesis between energy consumption and economic growth out of 119 countries the findings of the study suggest that an appropriate and effective public policy is required for all sample countries both in the short and long term while considering sustainable economic growth and development

a strategic model of european gas supply gasmod abstract this paper presents a model of the european natural gas supply gasmod which is structured as a two stage game of successive natural gas exports to europe upstream market and wholesale trade within europe downstream market and which explicitly includes infrastructure capacities we compare three possible market scenarios cournot competition in both markets perfect competition in both markets and perfect competition in the downstream with cournot competition in the upstream market eu liberalization we find that cournot competition in both markets is the most accurate representation of today s european natural gas market where suppliers at both stages generate a mark up at the expense of the final customer double marginalization our results yield a diversified supply portfolio with newly emerging lng exporters gaining market shares enforcing competition in the european downstream market would lead to lower prices and higher quantities by avoiding the welfare reducing effects of double marginalization binding infrastructure capacity restrictions strongly influence the results and we identify bottlenecks mainly for intra european trade relations whereas transport capacity in the upstream market is globally sufficient in the cournot scenario

the merit order effect a detailed analysis of the price effect of renewable electricity generation on spot market prices in germany the german feed in support of electricity generation from renewable energy sources has led to high growth rates of the supported technologies critics state that the costs for consumers are too high an important aspect to be considered in the discussion is the price effect created by renewable electricity generation this paper seeks to analyse the impact of privileged renewable electricity generation on the electricity market in germany the central aspect to be analysed is the impact of renewable electricity generation on spot market prices the results generated by an agent based simulation platform indicate that the financial volume of the price reduction is considerable in the short run this gives rise to a distributional effect which creates savings for the demand side by reducing generator profits in the case of the year 2006 the volume of the merit order effect exceeds the volume of the net support payments for renewable electricity generation which have to be paid by consumers

is energy security a driver for economic growth evidence from a global sample abstract this study examines whether energy security contributes to economic growth for a global sample of 74 countries covering the period from 2002 to 2013 the benchmark model is built based on an extended version of the cobb douglas production function ten measures of energy security are employed to capture five aspects of energy security including availability accessibility acceptability affordability and develop ability besides the whole sample we also conduct the panel data analysis on subsamples of countries based on different income levels using panel corrected standard errors pcse and feasible generalized least squares fgls techniques that correct for heterogeneity and autocorrelation and produce robust standard errors the empirical results appear to be relatively robust to these two estimation techniques overall we find that energy security enhances economic growth for both the whole sample and subsamples of countries meanwhile energy insecurity measured by energy intensity and carbon intensity variables has a negative impact on economic growth the results vary across subsamples for several cases the findings imply that at the global level energy for economic development energy security and climate change mitigation should be pursued as integrated themes since there are linkages among these three agendas

the origins of persistent current account imbalances in the post bretton woods era why do some countries run persistent current account surpluses why do others run deficits often over decades leading to enduring global imbalances such persistent imbalances are the root cause of many financial crises and a major source of international economic conflict we propose that differences in wage bargaining institutions explain a large share of imbalances through their effect on the trade balance in countries with coordinated wage bargaining wage growth in export industries can be restrained to ensure competitiveness leading to persistent trade surpluses we estimate the contribution of these institutions to trade balances in organisation for economic co operation and development oecd member countries since 1977 and find ample support for our hypothesis contrary to much of the literature the choice of fixed or floating exchange rate regimes has only a small effect on trade or current account balances in other words internal adjustment in surplus countries via wage bargaining institutions trumps external adjustment by deficit countries

price discrimination in competitive markets we present models in which price discrimination in the context of a two part price can occur in some competitive markets purchases take place in groups which choose which firms to patronize while firms are perfectly competitive with respect to groups they have some market power over individual consumers who are constrained by their groups choices we find that firms will charge an entry fee that is below marginal cost and the second part of the price is marked up above marginal cost the markup not only is positive but increases with the quality of the product

the european sovereign debt crisis the origin and propagation of the european sovereign debt crisis can be attributed to the flawed original design of the euro in particular there was an incomplete understanding of the fragility of a monetary union under crisis conditions especially in the absence of banking union and other european level buffer mechanisms moreover the inherent messiness involved in proposing and implementing incremental multicountry crisis management responses on the fly has been an important destabilizing factor throughout the crisis after diagnosing the situation we consider reforms that might improve the resilience of the euro area to future fiscal shocks

the effects of renewables in space and time a regime switching model of the italian power price abstract renewable energy production can exercise a downward pressure on electricity prices by partly crowding out conventional units characterized by higher marginal costs merit order effect yet congestion induced by renewables would partly offset the merit order effect in the congested zone unless renewables reduce the need for imports and allow the emergence of prosumers these congestion effects of renewables are hereby jointly tested with the merit order effect by means of an endogenous regime switching model wherein a regime corresponds to the observable status congested non congested of the grid the model is taken to data from the italian power exchange observed in 2012 and 2013 with a focus on the line connecting sicily with the south zone a frequent bottleneck in the italian transmission grid the results confirm the merit order effect previously detected in the literature and highlight a negative congestion effect i e renewables relieve congestion from sicily a systematic importer but not from the italian peninsula the exporting region this effect is mainly driven by the wind power in feed

neorealism and neoliberalism the classic dialectic between realist and liberal theories of international politics as expressed by robert o keohane ed in neorealism and its critics and richard rosecrance the rise of the trading state can be transcended neither paradigm singularly explains international behavior realism is the dominant approach but liberal theories of transnationalism and interdependence help to illuminate how national interests are learned and changed keohane and fellow critics argue that neorealism articulated definitively in kenneth waltz s theory of international politics 1979 elegantly systematizes realism but concentrates on international system structure at the expense of system process focused tightly on the concept of bipolarity waltz s theory tends toward stasis the unit state level unproductively becomes an analytical dumping ground as a neoliberal counterpoint rosecrance s argument does not go far enough in the tradition of commercial liberalism he argues that an open trading system offers states maneuverability through economic growth rather than through military conquest he tempers his argument with realist considerations of prudence but fails to clarify realist liberal links in his theory or to explore fully the connections between power and non power incentives influencing states behavior a synthesis of neorealism and neoliberalism is warranted a systemic theory using the former to analyze at the level of structure the latter more often at the level of process

the cinderella options a study of modernized renewable energy technologies part 1 a technical assessment abstract this paper examines the status of and prospects for renewable energy technologies it is argued that the prospects for obtaining large scale supplies are good especially in the industrialized countries and that sufficient evidence exists for them to be taken much more seriously in the energy policy process reasons for their low status include inadequate data and a scepticism born of past disappointments however a failure to transfer existing knowledge to the policy community and well documented institutional and psychological processes are probably more important a major change of attitudes is required and is in the long run inevitable but the process will not be easy together with energy efficiency and natural gas renewable sources will then emerge as the third leg of the triad which will lead the way out of the growing energy environmental impasse however the changes involved could either deepen or alleviate political conflicts a great deal will hinge upon the timing and path of the changes

independent regulatory agencies and rules harmonization for the electricity sector and renewables in the mediterranean region the paper analyses the existing regulatory framework for the electricity and renewables sectors and the role of regulatory agencies in northern africa and middle east countries under the promotion by the european union using data collected through an original survey directed at regulators ministry departments and energy companies of the southern mediterranean the study is aimed at assessing the extent of agencies independence looking at three main dimensions of independence regulatory instruments available to regulators and decision making autonomy regulators organizational autonomy and regulators accountability results show that those countries having established an independent regulator have a more credible regulatory framework than those countries in which such a body does not exist in particular the analysis shows that turkey croatia and jordan have defined a regulatory framework that limits administrative expropriation and consequently creates an environment more suitable for attracting investments in the electricity and renewables sector on the institutional ground this is probably related with the harmonization of regulatory standards promoted by the european union through the neighboring policy for the jordan case and the membership perspective in the turkish and croatian cases

ideas institutions and interests in the politics of cross border electricity interconnection greenlink britain and ireland abstract increasing electricity interconnection is necessary for both closer market integration and facilitating more renewable generation across the european union however progress on the ground has been slow this paper adds to the literature on the politics of interconnection through a case study of a proposed link between ireland and great britain we analyse how the institutional setting for investment has evolved at eu and member state level and how the influence of stakeholders is mediated by the ability of actors to define their interests and by institutional points of entry using this framework we examine the greenwire greenlink project we find first that developments in the institutional context especially the adoption of a new cap and floor regime for merchant investment by the gb regulator have had both positive and negative impacts on the project second we find that regulators and governments in the two markets have found it hard to define their interests in the project and its net social benefit due to informational complexities and changes in information over time third the project has met with local public opposition that is strong but which has little leverage due to a lack of institutional entry points

implicit auctioning on the kontek cable third time lucky implicit auctioning in europe is about eliminating cross border trade inefficiencies by internalizing crossborder trade into the day ahead auction procedures of the power exchanges that are already organizing trade nationally on the kontek cable implicit auctioning has first been implemented with no coupling between the relevant power exchanges followed by a volume coupling implementation and finally a one way price coupling implementation that is still operational today the main contribution of this paper is to compare the theoretical properties of these three implementations and to analyze their performance empirically we find that the third implementation is significantly outperforming the previous two implementations but in this third implementation stakeholders partly abandoned the volume coupling approach they initially believed to be a viable alternative and institutionally easier to implement

the impact of wind power generation on the electricity price in germany abstract this paper investigates the relationship between intermittent wind power generation and electricity price behaviour in germany using a garch model i evaluate the effect of wind electricity generation on the level and the volatility of the electricity price in an integrated approach the results show that variable wind power reduces the price level but increases its volatility this paper s results also indicate that regulatory change has stabilised the wholesale price the electricity price volatility has decreased in germany after a modification of the marketing mechanism of renewable electricity this gives confidence that further adjustments to regulation and policy may foster a better integration of renewables into the power system

comparative institutional advantage in the european sovereign debt crisis excessive fiscal spending is commonly cited as a root of the current european debt crisis this article suggests like others that the rise of competitiveness imbalances contributing to national imbalances in total borrowing is a better explanation for systemic differences toward economic and monetary union emu countries exposure to market speculation we identify one driver of this divergence a country s capacity to limit sheltered sector wage growth relative to wage growth in the manufacturing sector corporatist institutions that linked sectoral wage developments together in the surplus countries provided those with a comparative wage advantage vis a vis emu s debtor nations which helps explain why the emu core has emerged relatively unscathed from market speculation during the crisis despite the poor fiscal performance of some of the core countries during emu s early years using a panel regression analysis we demonstrate that rising differentials between public and manufacturing sector wage growth and wage governance institutions that weakly coordinate exposed and sheltered sectors are significantly correlated with export decline we also find that weak governance institutions are significantly associated with more prominent export decline inside as opposed to outside a monetary union

strategic eurasian natural gas market model for energy security and policy analysis formulation and application to south stream abstract the mathematical formulation of a strategic eurasian natural gas market model is presented the model represents horizontal oligopolistic relationships among producers bilateral market power between producer russia and transit ukraine countries detailed transport constraints and operation decisions over a 20 year time horizon to demonstrate the model s capabilities a financial and market analysis of the proposed south stream gas pipeline from russia via the black sea to south europe is summarized insights obtained include the following first expectations of high demand growth in europe and or transit risks do not justify the construction of the south stream pipeline because under all demand and ukraine transit interruption scenarios the net benefits to the south stream participants are negative the npv ranges from 1 9 billion bn to 7 4 bn second ukraine s perception of high transit market power vis a vis russia may trigger the construction of the otherwise unprofitable south stream project thus under ukraine s high transit market power scenario the npv of south stream ranges between 2 4 bn and 24 5 bn third we find that the south stream investment increases the efficiency of the european gas market under the following conditions i when gas demand in europe grows 2 per year up to 2030 ii when ukraine poses high transit market power or iii under a combination of severe transit risks through ukraine and low demand scenarios in europe it should be noted that the value of south stream to both its project sponsors and the market as a whole is much higher when ukraine exercises transit market power than under the high demand scenario therefore whether ukraine is likely to wield market power is crucial to the success of the south stream project because that is the only scenario in which the project yields both a positive expected npv to its sponsors and the highest value to the market as a whole

geo economic approach to energy security measurement principal component analysis abstract currently there is no single accepted methodology for measuring energy security while the prevailing scientific attitude is that energy security should be defined and quantified in a way to be able to follow rapid developments on the global economic and geopolitical scene considering the fact that the national economies represent an integral part of a dynamic international economy where external shocks global financial and economic crisis political conflicts war etc have the impact on energy prices and energy security in general the paper proposes a new geo economic concept of energy security the new approach differs from the existing ones as regards the fact that in addition to basic indicators it takes into account sovereign credit rating as a measure of economic financial and political stability as one of the decisive factors which determines global energy trade and the ability of national economies to be stable and secure when it comes to energy determination and testing of geo economic index of energy security was conducted by using the principal component analysis in the european union and in the selected countries of the world over a period of ten years 2004 2013 the measured values of a newly proposed geo economic index of energy security demonstrate significant deviations from the data obtained by using usual indicators of energy security observed individually gdp per capita has the greatest impact on the change in final value of geo economic index of energy security while the impact of sovereign credit rating is slightly less the study has shown that the least impact on energy security is exerted by energy dependence which is traditionally used as a proxy indicator of energy security and production of energy from renewable sources which is defined by the eu policy as one of the methods for the improvement of energy security due to the results obtained it is necessary to conduct further analysis of sovereign credit rating and to review the type and significance of the impact of energy dependence indicator as a measure of energy security in general

strategic investment in merchant transmission the impact of capacity utilization rules abstract in this paper we look at the relative merits of two capacity utilization regimes in the merchant electricity transmission network must offer mo where the entire capacity installed has to be made available for transmission and non must offer nmo where some capacity could be withheld we look at two specific cases i demand for transmission varies across time and ii vertical integration is allowed between investors in transmission network and electricity generators in the case of time varying demand under mo we find that a monopolist may underinvest in transmission when compared to nmo although nmo may lead to more capacity withholding in the case of vertical integration we find that when the market power is with the generators of the exporting node without vertical integration no welfare enhancing merchant investment would occur neither under mo nor nmo further if the generators in the importing node have market power in case vertical integration is allowed mo is better than nmo finally we also argue that the incentive to collude among various transmission network investors is mitigated with mo in place

social cost benefit analysis of electricity interconnector investment a critical appraisal abstract this paper examines the economic analysis social cost benefit analysis underlying two decisions to build an interconnector norned and the east west interconnector in europe the main conclusion is that current interconnector and transmission investment decisions in europe are unlikely to maximize social welfare the arguments are as follows i it is unclear how much demand for transmission capacity and interconnectors actually exists and thus the benefits of investment are unclear ii both analyses underlying the investments studied are incorrect to the point where in one case even the sign may be wrong iii the main criticism concerns the fact that they do not take the resulting changes in generator investment plans into account and ignore the potential benefits of increased competition iv several smaller issues can be improved such as the discount rate used v decisions at the european level are taken very differently and approval may depend on which authority grants approval vi interconnector decisions receive the most attention although most money goes to transmission investments two research recommendations for future improvements are formulated

understanding carbon lock in abstract this paper narrative argues that industrial economies have been locked into fossil fuel based energy systems through a process of technological and institutional co evolution driven by path dependent increasing returns to scale it is asserted that this condition termed carbon lock in creates persistent market and policy failures that can inhibit the diffusion of carbon saving technologies despite their apparent environmental and economic advantages the notion of a techno institutional complex is introduced to capture the idea that lock in occurs through combined interactions among technological systems and governing institutions while carbon lock in provides a conceptual basis for understanding macro level barriers to the diffusion of carbon saving technologies it also generates questions for standard economic modeling approaches that abstract away technological and institutional evolution in their elaboration the question of escaping carbon lock in is left for a future paper

a continuous model for multistore competitive location this paper presents a simple model to determine the location strategies of two retail firms planning to open a number of stores in a geographical market firms try to maximize their profit under a leader follower type competition in which the number of stores is made endogenous by the introduction of fixed costs a novel methodology is developed in which firms strategies are defined in terms of their location densities this methodology leads to a model that is solvable analytically and to several results on competitive location strategies first it is shown that if the follower decides to enter a market he enters at least as strongly as the leader second the leader can effectively deter entry even if she is severely cost disadvantaged however in some cases the leader is better off by allowing the follower to enter the market third the leader may also let the follower enter the market in some situations where she has a cost advantage it is also shown that in situations where both firms enter the market their location strategies are quite insensitive to model parameters

thinking big politics progress and security in the management of asian and european energy megaprojects this article examines four energy megaprojects two in europe and two in asia for each region a large natural gas pipeline project and an international project involving solar power from the desert is studied the natural gas projects are the nabucco project in europe and the trans asean gas pipeline network in asia the solar power from the desert projects are desertec in europe and gobitec in asia the article probes explanations of megaproject failure along social technical economic political and psychological dimensions we find that these projects though they are very different in nature and pertain to different regions all suffer from a similar set of problems too many stakeholders and stakeholder fragmentation cost overruns and the risk of accidents and attacks massive externalization of costs to third party stakeholders concentration of wealth and corruption and inflated expectations and biased projections we conclude by reflecting on lessons for not only the involved institutions and investors but energy analysts and the public at large

research note vertical information sharing in a volatile market when demand is uncertain manufacturers and retailers often have private information on future demand and such information asymmetry impacts strategic interaction in distribution channels in this paper we investigate a channel consisting of a manufacturer and a downstream retailer facing a product market characterized by short product life uncertain demand and price rigidity assuming the firms have asymmetric information about the demand volatility we examine the potential benefits of sharing information and contracts that facilitate such cooperation we conclude that under a wholesale price regime information sharing might not improve channel profits when the retailer underestimates the demand volatility but the manufacturer does not although information sharing is always beneficial under a two part tariff regime it is in general not sufficient to achieve sharing and additional contractual arrangements are necessary the contract types we consider to facilitate sharing are profit sharing and buyback contracts

a review of balancing costs in italy before and after res introduction abstract the massive introduction of res in electricity markets is recognized to have induced a merit order effect on wholesale prices while day ahead prices are likely to decline as res e production increases the effects on balancing market sessions are more ambiguous taking into account the northern italian zone characterized by a high solar pv and hydro penetration we provide empirical evidence that balancing quantities decreased while costs increased between two samples associated with low 2006 08 and high 2013 15 res levels we estimate balancing costs for different technologies and compare their dynamics across specific hours we find evidence of increasing balancing prices in particular market conditions that we interpret as a signal of strategic use of real time sessions by conventional producers prone to the merit order effect in the day ahead market we compare our results to those obtained in the german market where on the contrary balancing costs have decreased and postulate that the different market designs may explain these results our findings suggest that the italian policy makers should carefully monitor all trading sessions especially those close to real time to avoid the exercise of market power by few operators allowed to guarantee system security and additionally to promptly adopt a capacity market

spatially uneven development and low carbon transitions insights from urban and regional planning the ageing of existing energy system infrastructure the threat of climate change and uncertainty in the movement of energy prices have resulted in a widespread agreement on the need for a transition to a low carbon energy system yet the nature of this transition i e what when how and where and its socio economic outcomes at different scales are not well understood the interdependence of the energy sector and economic growth has been mostly studied at the national level via some general equilibrium or econometric models whilst sub national studies at community or urban levels mostly focus on the governance of transitions hence we suggest that a regional perspective to energy policy and research promises to integrate these two approaches by providing a more robust and comprehensive understanding of the implications of low carbon transitions as well as contributing to the development of more effective policies by building on recent ideas on geographical aspects of energy transitions this article offers insights on the changing relationship between the spatial organisation of economic activities and energy systems and identifies tools and methods from urban and regional planning to help with the delivery of efficient and equitable policy outcomes

shifting load through space the economics of spatial demand side management using distributed data centers demand side flexibility dsf in the electricity grid has become an active research area in recent years while temporal flexibility e g load shedding load shifting is already discussed intensively in literature spatial load migration still is an under researched type of dsf spatial load migration allows us to instantly migrate power consuming activities among different locations data centers dcs are power intensive and process information goods since information goods are easily transferable through communication networks power intensive processing of information goods is not necessarily tied to a specific location consequently geographically distributed dcs inherit in theory a considerable potential to globally migrate load we analyze the economics of spatially migrating load to provide balancing power using geographically distributed dcs we assure that neither of the participating electricity grids will be burdened by this mechanism by using historical data to evaluate our model we find reasonable economic incentives to migrate positive as well as negative balancing power in addition we find that current scenarios favor the migration of negative balancing power our research thus reveals realistic opportunities to virtually transfer balancing power between different market areas worldwide

how renewables will change electricity markets in the next five years photovoltaic pv cells onshore wind turbines internet technologies and storage technologies have the potential to fundamentally change electricity markets in the years ahead photovoltaic cells are the most disruptive energy technology as they allow consumers of all sizes to produce power by themselves new actors in the power market can begin operating with a new bottom up control logic unsubsidised pv markets may start to take off in 2013 fuelling substantial growth where pv power is getting cheaper than grid or diesel backup electricity for commercial consumers managing loads and achieving a good match between power consumption and weather dependent power production will likely become a key issue this consumption production balance may trigger massive innovation and investment in energy management technologies involving different kinds of storage and controls increasing autonomy and flexibility of consumers challenges the top down control logic of traditional power supply and pushes for a more decentralised and multi layered system how rapidly and smoothly this transformation occurs depends to a large extent on the adaptation speed of the regulatory framework and on the ability of market players to develop appropriate business models the paper discusses conflicts of interest hurdles and drivers opportunities and traps for this perspective

an assessment of the danish german cross border auctions abstract this paper presents an analysis of the auction prices at the cross border auction between west denmark and germany and between east denmark and germany the kontek cable monthly and annual transmission capacities appear to be more highly valued than daily transmission capacity on average the two cross border auctions show different trends the auctions between west denmark and germany exhibit a higher level of prices in the southbound direction and between east denmark and germany higher prices in the northbound direction we find a relatively strong correspondence in the pricing of products over different time frames daily monthly and annual auctions between west denmark and germany and a weak correspondence for the products between east denmark and germany in the daily auctions market players can decide whether to use their capacity after the clearing of the day ahead market while in the monthly and annual auctions they must decide whether to use their capacity prior to clearing if they choose not to use their capacity the use it or lose it principle applies the capacity is then subsequently released to the daily market since the daily cross border auctions are free of commitment they should be valued as options likewise in the monthly and annual auctions market players can choose not to nominate their capacity but as this must occur before the clearing of the day ahead market they will not know the directions of the power flows a priori if they nominate the capacity they must use it if the direction turns out to be wrong it is then possible to purchase capacity in the opposite direction in the daily auctions if market players can accurately predict the outcome of the spot markets day ahead the value of monthly and annual capacity should more closely reflect the value of an option thus one would expect the value of the monthly and annual capacity to be between the value of an option and an obligation although this suggests that the average price of daily capacity should be greater than monthly and annual capacity our data do not support this hypothesis the daily monthly and annual capacity auctions do not reflect the value of the underlying asset as specified by the appropriate valuation of the energy price differentials between west denmark and germany and east denmark and germany therefore market players are exposed to substantial variation in fees for congestion management on the cross border we study whether arbitrage improves over time and discern no obvious trend since the explicit auction procedure has not been cost efficient a better approach appears to be the new market coupling arrangement introduced on the kontek cable and on the border between west denmark and germany with the result that market players will pay a congestion management fee i e area price difference equal to the energy price differential resulting from the market coupling mechanism

a regulatory assessment of the electricity merchant transmission investment in eu current eu energy policy calls for a well integrated internal energy market by 2020 aimed at achieving interconnection of at least 10 of the installed electricity production capacity for all member states ms in 2030 this target will increase to 15 expanding to include the construction of electricity highways to connect ms and non eu neighbouring countries in order to fulfil energy and climate goals while most cross borders interconnections are envisaged as regulated lines private players will play a significant role in increasing interconnection via the merchant transmission investment mti exception by reviewing the procedural and substantive treatment of the existing five mti interconnectors this paper evaluates whether the existing legal and regulatory framework adopted in the eu represents a suitable model for the development of cross border interconnections further the paper explores the mti exception as a potential model for cross border interconnection with non eu neighbouring countries this analysis demonstrates that mti s potential contribution would not significantly impact the achievement of the 2020 target moreover the existing regulatory framework for merchant lines among ms is not apt for mti developed between ms and non eu countries since the interconnection developed with non eu neighbouring countries to date has necessitated non market characteristics too extraordinary to be practical on a continuing basis

third degree price discrimination and consumer surplus this paper considers the effects of monopoly third degree price discrimination on aggregate consumer surplus discrimination is likely to reduce surplus relative to that obtained with a uniform price but surplus can rise under reasonable conditions if the ratio of the pass through coefficient to the price elasticity at the uniform price is higher in the market with the higher price elasticity then surplus is larger with discrimination for a large set of demand functions the relatively high pass through coefficient implies a large price reduction in this market with logit demand functions surplus is higher with discrimination if pass through is above 0 5

energy and food security linkages through price volatility abstract this study examines the linkages between energy price and food prices over the period 2000 2016 by using a panel var model in the case of eight asian economies our results confirm that energy price oil price has a significant impact on food prices according to the results of impulse response functions agricultural food prices respond positively to any shock from oil prices our results show that there is a linkage between energy and food security through price volatility since inflation in oil price is harmful for food security it would be necessary to diversify the energy consumption in this sector from too much reliance on fossil fuels to an optimal combination of renewable and nonrenewable energy resources that will be in favor of not only the energy security by also the food security in addition the paper found that the impact of biofuel prices on food prices is statistically significant but explains less than 2 of the food price variance however by increasing the demand for biofuel there should be more concern about the global increase in agricultural commodities prices and endangering food security especially in vulnerable economies

integrated north sea grids the costs the benefits and their distribution between countries abstract a large number of offshore wind farms and interconnectors are expected to be constructed in the north sea region over the coming decades creating substantial opportunities for the deployment of integrated network solutions creating interconnected offshore grids that combine cross border links and connections of offshore plants to shore offers multiple economic and environmental advantages for europe s energy system however despite evidence that integrated solutions can be more beneficial than traditional radial connection practices no such projects have been deployed yet in this paper we quantify costs and benefits of integrated projects and investigate to which extent the cost benefit sharing mechanism between participating countries can impede or encourage the development of integrated projects three concrete interconnection case studies in the north sea area are analysed in detail using a national level power system model model outputs are used to compute the net benefit of all involved stakeholders under different allocation schemes given the asymmetric distribution of costs and benefits we recommend to consistently apply the positive net benefit differential mechanism as a starting point for negotiations on the financial closure of investments in integrated offshore infrastructure

electricity market integration decarbonisation and security of supply dynamic volatility connectedness in the irish and great britain markets abstract this study investigates the volatility connectedness between the irish and great britain electricity markets and how it is driven by changes in energy policy institutional structures and political ideologies we assess various aspects of this volatility connectedness including static unconditional vs dynamic conditional symmetric vs asymmetric characteristics between 2009 and 2018 we find that the volatility connectedness is time varying and it is significantly affected by important events policy reforms or market re designs such as brexit oil price slump an increasing share of renewables and fluctuations in the exchange rates our asymmetric analysis shows that magnitude of the good volatility connectedness is marginally larger than that of the bad volatility connectedness our result suggests that good volatility levels would be even higher once the irish market adopts the carbon price floor therefore supporting renewable generation by setting an appropriate price of carbon in interconnected wholesale electricity markets will improve market integration

the economic consequences of brexit energy in this paper we raise a number of issues that are important for the uk to consider in the light of its decision to leave the european union eu the first of these is the nature of the eu single market in electricity and gas and the uk s role within this the second is the nature of uk energy policy in the light of brexit and the opportunities for changing this and third we consider some of the key issues to be addressed in a negotiating position with the eu

a preliminary assessment of the market coupling arrangement on the kontek cable this paper presents a preliminary assessment of the market coupling arrangement on the kontek kt cable between east denmark and germany and an assessment of the original auction mechanism kt the new spot price area was introduced in germany on october 5 2005 to facilitate a market coupling arrangement on the kt cable between east denmark and germany we would expect the kt price to correlate more with the european energy exchange eex price because arbitrage normally levelizes the price however spot prices in late 2005 were both high and volatile because congestion management practices in sweden transferred internal bottlenecks to the cable between sweden and east denmark since spot prices were equal in east denmark and the kt area for a substantial time it implies that some hours had no congestion on the kt cable market players valued the previous monthly auctions for transmission capacity more than the daily auctions compared to the daily auctions market players received smaller payoffs on average for the market coupling arrangement and the smallest payoffs for the monthly auctions

the political economy of the euro crisis this article introduces the special issue on the political economy of the euro crisis which aims to improve our understanding of the causes consequences and implications of the highly unusual nature of this crisis a financial crisis among developed countries within a supranational monetary union the article provides a brief chronology of the crisis discusses its underlying causes and reviews the ways in which comparative and international political economy can help us understand the crisis the article then discusses the individual and collective contributions of the articles in the special issue and discusses possible future research paths on the political economy of the euro crisis we conclude with a brief discussion of how a political economy perspective informs our understanding of the long term prospects for the eurozone and european integration

the geopolitics of cross border electricity grids the israeli arab case abstract countries often attempt to establish regional electricity grids however whereas research on natural resources frequently seeks to understand policy outcome through a geopolitical prism when it comes to electricity studies the prism is always economic or technical hence this study is a first attempt to identify the geopolitical dimension of cross border electricity grids the study argues that success in establishing electricity grids requires identifying how the geopolitical dimension interplays with the physical dimension to examine the role of these geopolitical bottlenecks the study examines negotiation protocols spanning over 15 years on establishing ten grid connections between israel and its arab neighbors it finds that electricity geopolitics has been used both as a platform for deeper international cooperation and as a stick against neighboring states when policies are driven by a peace dividend proposals for grid connection appear to evolve and overcome the dependency and the security economy bottlenecks when relations deteriorate proposals for grid connections appear to undergo reconsideration and to be held hostage by higher politics if when and how electricity grids materialize is a function of the nature of the electricity network as a twofold package and of the ability of the planning process to accommodate geopolitical uncertainty

escaping carbon lock in this article explores the climate policy implications of the arguments made in understanding carbon lock in unruh 2000 which posited that industrial countries have become locked into fossil fuel based energy systems through path dependent processes driven by increasing returns to scale carbon lock in arises through technological organizational social and institutional co evolution culminating in what was termed as techno institutional complex tic in order to resolve the climate problem an escape from the lock in condition is required however due to the self referential nature of tic escape conditions are unlikely to be generated internally and it is argued here that exogenous forces are probably required

green stimulus green recovery and global imbalances this paper assesses the extent to which g20 green stimulus initiatives enacted during the 2008 9 recession have instigated a global green recovery and how further green recovery policy initiatives by the g20 relate to concerns about chronic fiscal deficits and global imbalances implementing further green measures will require g20 economies to commit to increased public investments new pricing policies improving regulations more aid disbursements and other policy changes although there may be concern that these additional initiatives could worsen the chronic fiscal deficits and structural imbalances if properly enacted such a green economic recovery strategy should help alleviate rather than worsen unstably large fiscal deficits long term real interest rate rises and inflation and global imbalances

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

does large price discrimination imply great market power abstract a simple model demonstrates that there is no theoretical connection between the extent of price discrimination and the extent of market power

absolute and relative gains in international relations theory the problem of absolute and relative gains divides neoliberal institutionalism and structural realism the former assumes states focus primarily on their absolute gains and emphasizes the prospects for cooperation the latter supposes states are largely concerned with relative gains and emphasizes the prospects for conflict existing work in international relations theory generally traces the differences between these two theories to different assumptions about states preferences using a simple game theoretic model this essay offers a reformulation of the problem of absolute and relative gains that links changes in the states behavior the feasibility of cooperation and especially the states concern for relative versus absolute gains explicitly to changes in the constraints facing the states many of the differences between neoliberal institutionalism and structural realism appear as special cases of the model

the adoption of state electricity regulation the role of interest groups this paper examines the adoption of state electricity regulation around the beginning of the 20th century i model this decision as a hazard rate to determine what influenced the adoption of state regulation i find that adoption is positively correlated with capacity shortages greater wealth and lower residential electricity penetration rates these results suggest that state regulation responded to regulatory inefficiencies and residential consumer interests in addition adoption rates were higher in states that had a strong industrial and coal mining presence these results are consistent with the interest group and contracting theories of regulation states began replacing municipal regulation of electric utilities with state regulation in 1907 despite the long history surprisingly little is known about the causes of the regime shift in this paper i estimate a hazard model that defines the probability of adopting state regulation as a function of variables that measure the potential benefits and costs of a number of interest groups the shortage of installed capacity and concurrent levels of electricity prices and profits the results shed light on which theories of regulation are most consistent with the data i find evidence that is consistent with the interest group theory of regulation which began with peltzman 1976 and the contracting theory of regulation attributed to priest 1993 the interest group theory of regulation centers around private interest group competition regulators respond to the pressures of interest groups one testable implication of the interest group theory is that if state regulation benefited a certain class of consumers such as residential consumers at the expense of another class of consumers the

natural gas supply stability and foreign policy abstract this article studies factors that affect stability of supply of natural gas it examines the relative influence of political relations between the involved states on the stability of supply the article identifies the factors that affect the propensity of a state to use disruption of natural gas supply in order to promote foreign policy goals the article is based on the study of thirty five supply relations and two case studies the article claims that disruption of supplies can be initiated not only by supplier states but transit and consumer states it claims that natural gas supply relations generally take three forms neither side is dependent on the gas trade one side is dependent on the gas trade or the sides are interdependent in the gas trade cases of significant asymmetry of the degree of dependence in the gas trade are most likely to be exploited by the less dependent party for foreign policy gain the article claims that the prevailing political relations between gas trading states are only one of the factors affecting the stability of supply

the arguments for and against ownership unbundling of energy transmission networks abstract the question this paper addresses is what is the evidence for the superiority of the ownership unbundled transmission models i e uk or nord pool hybrid over other models we assess the theoretical costs and benefits of ownership unbundling and judge these to be generally positive though these may be potentially offset by the actual reorganisation costs of the ownership unbundling process next we assess the empirical evidence this is in two forms econometric evidence from samples of countries and case studies of reforms in particular jurisdictions the econometric evidence is weak due to problems with simultaneity of reform steps and a lack of studies but the case study evidence is compelling we conclude with a discussion of the issues faced by countries considering implementing ownership unbundling we conclude that evidence seems to be that ownership unbundling of transmission is a key part of energy market reform in the most successful reform jurisdictions

strengthening of energy security low carbon growth in asia role of regional energy cooperation through trade abstract prudent demand supply management of energy is pivotal for the energy security of the countries and transitions towards the sustainable low carbon energy system this study empirically investigates the existing demand supply gaps of energy in the south though east asian stea countries and analyzes how the gaps can be minimized most efficiently through intraregional energy trade stochastic frontier gravity model extended with the determinants of efficiency models used for both primary energy and renewable energy goods reg trade the result implies that for most of the countries intraregional export of primary energy as well as reg are positively influenced by gross domestic products gdp of the exporting and importing countries tariff and distance adversely affect the exports while the implication of cross exchange ratio seems minimal in both cases regional trade agreements rta are also found to have notable positive impact on intraregional trade results show that china and thailand are the most efficient in this intraregional primary energy export while bangladesh and myanmar remain the least efficient china and japan are the most efficient in reg exports while bangladesh remains the least efficient on average the whole region has the weighted export efficiency of 56 5 in intraregional primary energy trade and 63 1 in reg trade the determinants of efficiency model reveals that institutional quality better infrastructure goods market efficiency and technological readiness have reasonable impacts to enhance the countries intraregional energy trade efficiencies

measuring the competitiveness benefits of a transmission investment policy the case of the alberta electricity market transmission expansions can increase the extent of competition faced by wholesale electricity suppliers with the ability to exercise unilateral market power this can cause them to submit offer curves closer to their marginal cost curves which sets market clearing prices closer to competitive benchmark price levels these lower wholesale market clearing prices are the competitiveness benefit consumers realize from the transmission expansion this paper quantifies empirically the competitiveness benefits of a transmission expansion policy that causes strategic suppliers to expect no transmission congestion using hourly generation unit level offer output market clearing price and congestion data from the alberta wholesale electricity market from january 1 2009 to july 31 2013 an upper and lower bound on the hourly consumer competitiveness benefits of this transmission policy is computed both of these competitiveness benefits measures are economically significant which argues for including them in transmission planning processes for wholesale electricity markets to ensure that all transmission expansions with positive net benefits to electricity consumers are undertaken
