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

industry classifications and return comovement a company s industry affiliation is commonly used to construct homogeneous stock groupings for portfolio risk management relative valuation and peer group comparisons a variety of industry classification systems have been adopted however creating disagreements as to companies industry assignments this analysis of the global industry classification system gics and fama french system indicates that common movement in returns and operating performance resulting from industry effects is stronger for stocks of large companies than for those of small companies also increasingly fine levels of disaggregation improve discrimination up to six digit gics codes after which the benefits tail off stock groupings based on industry exhibit stronger out of sample homogeneity than groups formed from statistical cluster analysis

the effects of human resource management practices on productivity a study of steel finishing lines the authors investigate the productivity effects of innovative employment practices using data from a sample of thirty six homogeneous steel production lines owned by seventeen companies the productivity regressions demonstrate that lines using a set of innovative work practices which include incentive pay teams flexible job assignments employment security and training achieve substantially higher levels of productivity than do lines with the more traditional approach which includes narrow job definitions strict work rules and hourly pay with close supervision their results are consistent with recent theoretical models which stress the importance of complementarities among work practices

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

energy security and renewable electricity trade will desertec make europe vulnerable to the energy weapon abstract solar power imports to europe from the deserts of north africa as foreseen in the desertec concept is one possible way to help decarbonising the european power sector by 2050 however this approach raises questions of threats to european energy security in such an import scenario particularly in the light of increasing import dependency and russia s use of the energy weapon in recent years in this paper we investigate the threat of north african countries using the desertec electricity exports as an energy weapon we develop and use a new model to assess the interdependence the bargaining power symmetry operationalised as costs of a disruption in a future renewable electricity trade between north africa and europe if europe maintains current capacity buffers some demand response capability and does not import much more than what is described in the desertec scenario it is susceptible to extortion and political pressure only if all five exporter countries unite in using the energy weapon europe is not vulnerable to extortion by an export cut from only one country as the european capacity buffers are sufficient to restore the power supply no single exporter country would have sustained bargaining power over europe

perception of risks in renewable energy projects the case of concentrated solar power in north africa the world needs to reduce greenhouse gas emissions to prevent climate change while meeting the energy needs of developed and developing economies recent studies suggest that generation of electricity from concentrated solar power in north african countries and its transmission to europe could provide european and north african partners with low carbon electricity the private capital will be likely required to achieve the scale of new investment and yet the north african region experience difficulties with sustaining high levels of foreign direct investment from the private sector the literature identifies a number of risks as barriers to investment and we examine these in the particular context of renewable energy development we conducted three stages of interviews with stakeholders to learn their perceptions of the risks most likely to affect renewable energy projects three class of risks regulatory political and force majeure which includes terrorism stand out as being of high concern of these regulatory risks are perceived as being the most consequential and the most likely to occur this suggests that attention to building the capacities of north african countries to develop implement and enforce sound regulations in a transparent manner could be an important step in promoting renewable energy cooperation with europe

intertemporal cost allocation and managerial investment incentives a theory explaining the use of economic value added as a performance measure this paper provides a formal analysis of how managerial investment incentives are affected by alternative allocation rules when managerial compensation is based on accounting measures of income that include allocations for investment expenditures the main result is that there exists a unique allocation rule that always induces the manager to choose the efficient investment level the income measure created by this allocation rule is usually referred to as residual income or economic value added

oil vulnerability index of oil importing countries abstract this paper assesses the relative oil vulnerability of 26 net oil importing countries for the year 2004 on the basis of various indicators the ratio of value of oil imports to gross domestic product gdp oil consumption per unit of gdp gdp per capita and oil share in total energy supply ratio of domestic reserves to oil consumption exposure to geopolitical oil market concentration risks as measured by net oil import dependence diversification of supply sources political risk in oil supplying countries and market liquidity the approach using the principal component technique has been adopted to combine these individual indicators into a composite index of oil vulnerability such an index captures the relative sensitivity of various economies towards developments of the international oil market with a higher index indicating higher vulnerability the results show that there are considerable differences in the values of individual indicators of oil vulnerability and overall oil vulnerability index among the countries both inter and intraregional

reaching for the stars who pays for talent in innovative industries innovative firms need to hire and motivate highly talented workers this article connects the potential returns to innovation to the structure of compensation for skilled employees we show that the software firms that operate in software sectors with high potential upside gains to innovation pay more to star workers than do other firms that operate in stable markets firms operating in product domains with highly skewed positive returns pay employees more in up front starting salaries and offer higher compensation growth the large estimated effects on earnings are robust to the inclusion of a wide range of controls for worker and firm characteristics

on the european responsibility in the agricultural multilateral trade negotiations modelling the impacts of the common agricultural policy the present round of multilateral trade negotiations is still deadlocked over agricultural trade the european union eu is urged by its trading partners to open its agricultural markets economic evaluations of trade liberalisation scenarios unanimously conclude that a substantial opening of agricultural markets is required for a successful welfare improving doha round in this paper we perform new evaluations to identify precisely the contributions of the european farm policy and to examine the robustness of these evaluations in the representation of this complex policy using the same specifications as in major previous studies our first simulations show that the eu has a major responsibility in delivering significant gains to the developing countries on the other hand when we conduct the same experiments with a more relevant calibration and modelling of the european farm policy instruments the gains that these developing countries may reap from the eu liberalisation are considerably reduced accordingly the current charge against the eu is simply inopportune

subjective performance measures in optimal incentive contracts objective measures of performance are seldom perfect in response incentive contracts often include important subjective components that mitigate incentive distortions caused by imperfect objective measures this paper explores the combined use of subjective and objective performance measures in respectively implicit and explicit incentive contracts naturally objective and subjective measures often are substitutes sometimes strikingly so we show that if objective measures are sufficiently close to perfect then no implicit contracts are feasible because the firm s fallback position after reneging on an implicit contract is too attractive we also show however that objective and subjective measures can reinforce each other if objective measures become more accurate then in some circumstances the optimal contract puts more weight on subjective measures because the improved objective measures increase the value of the ongoing relationship and so reduce the firm s incentive to renege we also analyze the use of subjective weights on objective performance measures and provide case study evidence consistent with our analyses

an economic approach to influence activities in organizations members of organizations spend considerable time effort and ingenuity attempting to influence decision makers such influence activities may bring benefits to the organization but they also involve real costs this essay offers an economic rationale for such influence activity as representing rational self interested behavior in the presence of informational asymmetries and an analysis of how the design of the organization s structure and policies should respond to the incentives for attempting influence it is posited that information valuable for the organization s decision making is directly available only to members of the organization who have some personal stake in the decisions these individuals may then have an incentive to try to manipulate the information they develop and provide in order to influence the resulting decisions to their benefits this can be costly both in degrading the quality of decision making and in diverting the attention and effort of the organization s members from more productive activities the organization has three different methods it can employ to discourage excessive influence activities and to encourage more directly productive uses of time and effort it can limit access to decision makers and participation in decision making it can alter its decision making criteria to favor those performing well in productive activities and it can provide direct financial incentives to encourage the desired allocation of effort it is shown that an efficiently designed organization will use such financial incentives only as a last resort instead it will always first alter its decision participation policies and decisionmaking criteria

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

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

is it inefficient investment that causes the diversification discount diversified conglomerates are valued less than matched portfolios of pure play firms recent studies find that this diversification discount results from conglomerates inefficient allocation of capital expenditures across divisions much of this work uses tobin s q as a proxy for investment opportunities therefore hypothesizing that q is a good proxy this paper treats measurement error in q using a measurement error consistent estimator on the sorts regressions in the literature i find no evidence of inefficient allocation of investment the results in the literature appear to be artifacts of measurement error and of the correlation between investment opportunities and liquidity diversif ied conglomerates appear to trade at a discount relative to matched portfolios of pure play firms studies documenting this stylized fact include lang and stulz 1994 berger and ofek 1995 comment and jarrell 1995 and servaes 1996 recent empirical work has sought to find the source of this diversification discount building on the theoretical work in milgrom and roberts 1990 stein 1997 and scharfstein and stein 2000 on the inefficiency of internal capital markets this literature has asked specifically whether diversified firms allocate their capital expenditures inefficiently across divisions the canonical answer has been yes and has been supported by two types of evidence first studies such as lamont 1997 shin and stulz 1998 shin and park 1998 and rajan servaes and zingales 2000 all find that internal capital markets in conglomerates transfer funds across divisions in a suboptimal manner second studies such as berger and ofek and scharfstein 1998 provide evidence suggesting that the divisions of conglomerates do not respond adequately to investment opportunities in comparison to single segment firms however these findings about divisional investment may be an artifact of measurement error most of these studies rely on tobin s q the market value of the capital stock divided by its replacement value as a proxy for investment opportunities and tobin s q is likely to be a poor proxy shin and stulz

how much of the diversification discount can be explained by poor corporate governance we investigate whether the diversification discount occurs partly as an artifact of poor corporate governance in panel data models we find that the discount narrows by 16 to 21 when we add governance variables as regression controls we also estimate heckman selection models that account for the endogeneity of diversification and dynamic panel generalized method of moments models that account for the endogeneity of both diversification and governance we find that the diversification discount persists even with these controls for endogeneity however in selection models the discount disappears entirely when we introduce governance variables in the second stage and in dynamic panel gmm models the discount narrows by 37 when we include governance variables

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

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

optimal investment portfolio in renewable energy the spanish case abstract this article presents a model for investing in renewable energies in the framework of the spanish electricity market in a way that risk is minimised for the investor while returns are maximised the model outlined here is based on an economic model for calculating cash flows intended to obtain the internal rate of return irr of the different energies being studied wind photovoltaic mini hydro and thermo electrical the irrs obtained are considered the returns on investments while their standard deviations are considered associated risks in order to minimise risk a comprehensive portfolio of investments is created that includes all of the available energies by means of a system of linear equations the solution of the linear system is graphically checked using the efficient frontier method for the different financing options several case studies within the renewable energies plan per is its spanish abbreviation that is in force in spain in the period 2005 2010 are analysed in order to illustrate the method as are other case studies using different types of financing helping us to reach the pertinent conclusions

fruitful symbiosis why an export bundled with wind energy is the most feasible option for north african concentrated solar power abstract the idea of generating electricity in north africa using concentrating solar thermal power csp has been around for some time now but has recently gained momentum through the mediterranean solar plan msp and the formation of the desertec industrial initiative this paper argues that while the large scale deployment of csp in north africa does not seem economically attractive for either european or african institutions or countries on their own at present combining domestic use and electricity exports could be profitable for both parties a detailed economic portfolio covering both solar and wind power plants can achieve competitive price levels which would accelerate the diffusion of solar technology in north africa this portfolio could be financed partially by exporting electricity from solar thermal plants in north africa via hvdc interconnections to european consumers sharing the costs in this way makes it possible to generate solar electricity for the domestic market at a reasonable cost some of the electricity produced from the solar power plants and wind parks in north africa is sold on european energy markets in the form of a long term contracted solar wind portfolio which would qualify for support from the financial incentive schemes of the european member states e g feed in tariffs this transfer of green electricity could help to meet the targets for energy from renewable energy sources res in the eu member states as the new eu directive of 2009 opened the european electricity market to imports from third states

financial risk reduction in photovoltaic projects through ocean atmospheric oscillations modeling abstract the impact of climate change on society has increased the interest to deploy renewable energies and to understand climate climate variability is partly predictable and is a fundamental factor in explaining financial risk in renewable energy projects current methodologies used for risk assessment do not appropriately account for climate predictability we found limited literature on risk reduction on pv projects through the modeling of predictable components of solar radiation and ocean atmospheric oscillations allowing us to present original proposals to fill these voids a new profit model for pv plants was developed capturing this predictable climate information the proposed methodology is potentially applicable to hydro wind and other renewable resources and allows leaving aside predictable climate components from the project s risk calculation the model was tailored for the risk assessment of pv investments and is applied over 10 geographical areas across chile the largest pv market in latin america where climate is strongly affected by 3 ocean atmospheric oscillations el nino southern oscillation southern annular mode and indian ocean dipole using the model in these regions allows reducing the monthly financial the risk to reduce by 60 81 compared to traditional methodology for a 100 mw pv project located in those areas this means reducing annualized risk from 4 93 to 7 88 mm usd year traditional model to 1 11 2 38 mm usd year proposed model modeling of ocean atmospheric oscillations allows achieving the greatest risk reduction between the cities of copiapo and coquimbo north central regions decreasing their influence towards the extreme latitudes their risk reduction will depend on the quality of the model and may have strong implications for both investors and financial institutions it could also impact competition in the energy sector due to possible asymmetries of information to facilitate extending the use of the model elsewhere the incorporation of subsidies is discussed

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

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

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

solar power investment in north africa reducing perceived risks abstract climate protection targets for mid century imply a need to scale up european renewable power production to a level that may exceed the available land area within europe s borders one attractive solution from a cost and feasibility perspective is the development of large scale concentrating solar power plants in north africa and the middle east however these developments are seen by many people as risky in terms of both european energy security and in terms of the risks faced by project developers in this paper we focus on the latter of theses issues first we examine the risks that project developers are most concerned about and identify these as being associated not with terrorism and rogue state behavior but rather with corruption and inefficient and unpredictable bureaucracies second we identify a range of policy approaches that can reduce these risks either by mitigating their consequences or by seeking to eliminate their underlying causes third we investigate the financial benefits of taking such steps to reduce or eliminate investment risks we find the potential savings to european electricity consumers to exceed 200 billion

the uruguay round agreements impact on developing countries abstract implementation of the results of uruguay round will bring about significant increases in trade investment income and welfare for developing countries this derives from increased market access to developed countries markets and from enhanced efficiency originating from their own liberalization commitments although the distribution of benefits will be uneven developing countries will also benefit from improved rules for trade and investment coupled with enhanced institutional enforcement of these rules and greater exposure to global competition within a more predictable secure and credible international trading environment to maximize the benefits however developing countries will need to continue with recent unilateral reforms to improve their supply response

why the wto is deadlocked and what can be done about it the gatt was hugely successful yet its successor organisation is to date failing this paper argues that the expansion in both scope and membership make it radically more difficult for a purely bargain based organisation to succeed three factors limit the scope for deals that would be recognised as mutually beneficial many developing countries are accustomed to transfers rather than bargains the poorest countries have no basis for bargaining and even where mutual advantage is possible it requires cross sectoral deals which are only feasible with new rules that are unattractive to many wto members the paper proposes solutions to these new problems it proposes an explicit component of transfer in the form of non reciprocated liberalisation it proposes a plurilateral solution to the tension between rules and sovereignty it links these through a grand bargain that offers transfers in return for plurilateralism for the marginalised countries it proposes time bound preferences in oecd markets along the lines of agoa finally to recreate for the larger developing countries similar incentives for liberalisation to those previously achieved for developed countries it proposes a limited mfn through which they could restrict their liberalisations to include only other developing countries

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

internal capital markets and firm level compensation incentives for division managers do multidivisional firms structure compensation contracts for division managers to mitigate incentive problems in their internal capital markets i find evidence that compensation and investment incentives are substitutes firms providing a stronger link to firm performance in incentive compensation for division managers also provide weaker investment incentives through the capital budgeting process specifically as the proportion of incentive pay for division managers that is based on firm performance increases division investment is less responsive to division profitability these findings are generally consistent with a model of influence activities by division managers in interdivisional capital allocation decisions

garment industry in sri lanka and the removal of gsp plus by eu the ready made garment industry plays an important role in sri lanka both in terms of export earnings and poverty alleviation through employment generation following the removal of gsp plus by eu in 2010 on the basis of alleged human right violations by the sri lankan government during the last stage of the civil war in 2009 and after it currently faces serious challenges in exporting to the eu its major market given the important role of the ready made garment industry in poverty alleviation through employment generation the impact of removal of gsp plus on the poor is examined in this paper the empirical results of this study demonstrate that poverty and income inequality are expected to be exacerbated in sri lanka as a result of the removal of gsp plus by the eu using non economic reasons such as human rights violation the results are also relevant for the renewed emphasis on trade preferences as a potential instrument for the millennium development goals and the debate on how trade preferences are to be designed to maximise their effectiveness in stimulating a manufacturing supply response

the price of policy risk empirical insights from choice experiments with european photovoltaic project developers managing the transition to a renewable energy future is an important policy priority in many countries solar photovoltaic pv technology is expected to make an important contribution but due to relatively higher cost its growth to date has been largely driven by public policy notably feed in tariffs feed in tariffs have been implemented in various countries however with widely differing outcomes in terms of installed pv capacity previous research indicates that the level of policy risk may be an important driver for differences in renewable energy policy effectiveness more specifically we suggest that investors who take a decision between pv investment opportunities in different countries carefully weigh feed in tariff induced returns against a set of policy risks and choose the country with the most favorable risk return profile we empirically test this model based on a stated preference survey among european pv project developers consisting of 1575 choice decisions by 63 investors the findings of our study demonstrate that risk matters in pv policy design and that a price tag can be attached to specific policy risks such as the duration of administrative processes or uncertainty induced by an approaching capacity cap governments can build on our empirical results to design policies that will be effective in attracting private pv investment while at the same time maintaining efficiency by providing an adequate compensation for policy risk

a meta analysis of general and partial equilibrium simulations of trade liberalisation under the doha development agenda model based simulation of welfare effects is commonly used to make a case for trade liberalisation and to inform participants a nd stakeholders in trade negotiations however the simulated welfare effects of trade liberalisation vary greatly even across studies that model similar liberalisation scenarios this

a signal jamming theory of predation we propose a new theory ofpredation based on signal jamming in our model the predator s characteristics are common knowledge while the entrant is uncertain of his own future profitability the entrant uses his current profit to decide whether to remain in the market and the predator preys to jam or interfere with this inference problem thus our model differs from those based on reputation effects in which the predator preys to signal information about himself

a development friendly prioritisation of doha round proposals agriculture looms large on the wto s agenda it was the first substantive item listed in the work programme of the ministerial declaration launching the doha round and it was arguably at the centre of the failure at cancun developing countries made it clear both before and during the cancun meeting that progress on agriculture was their primary objective negotiations in other areas have received less attention and progressed more slowly this paper considers that prioritisation and suggests that the interests of developing countries in the current round of trade negotiations are much broader than is suggested by the narrow range of agricultural issues that have dominated negotiations a true development round would require a significant reprioritisation of many areas of the wto s current agenda

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

are internal capital markets efficient using segment information from compustat we find that the investment by a segment of a diversified firm depends on the cash flow of the firm s other segments but significantly less than it depends on its own cash flow the investment by segments of highly diversified firms is less sensitive to their cash flow than the investment of comparable single segment firms the sensitivity of a segment s investment to the cash flow of other segments does not depend on whether its investment opportunities are better than those of the firm s other segments

evidence on the role of cash flow for investment abstract recent work in macroeconomics argues that imperfections in capital markets may lead to business cycle fluctuations by propagating relatively modest shocks evidence for such a mechanism also known as the financial accelerator consists largely of firm level studies showing that cash flow is an important predictor of investment but this evidence is often viewed with skepticism because cash flow is also a good indicator of investment opportunities in this paper we develop a framework for estimating the extent to which the predictive power of cash flow can be attributed to its role as a fundamental versus its role in alleviating credit frictions for firms with access to commercial paper and bond markets we find that the perfect capital markets model of investment can fully account for the role of cash flow for firms with only limited access to capital markets as indicated by lack of participation in public debt markets however investment appears to be excessively sensitive to fluctuations in cash flow these results thus clarify the role of cash flow in investment equations and provide support for the existence of a financial accelerator

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

the capital budgeting process incentives and information we study the capital allocation process within firms observed budgeting processes are explained as a response to decentralized information and incentive problems it is shown that these imperfections can result in underinvestment when capital productivity is high and overinvestment when it is low we also investigate how the budgeting process may be expected to vary with firm or division characteristics such as investment opportunities and the technology for information transfer there is general agreement that investment decisions are the most important decisions made by corporations the choice of projects and the level of investment is critical not just for stakeholders of the firm but also for the economic well being of society as a whole it has been alleged that u s firms invest too little and tend to overemphasize short term results for example porter 1992 citing poterba and summers 1992 asserts that u s firms use hurdle rates to evaluate investment projects that are higher than their estimated costs of capital to understand the investment behavior of firms one must consider both the process by which external capital is made available to firms and the process by which internally and externally raised capital is allocated to investment projects within the firm considerable attention has been paid to how firms raise external capital the fundamental insight in this area is the celebrated result of modigliani and miller mm that capital structure is irrelevant in the absence of capital market frictions accordingly in the three decades since their contribution research on how external capital is raised has focused on market frictions including information and incentive problems relatively little research has focused on the internal allocation process and its relationship to the organization of the firm modern finance theory prescribes allocating capital according to the net present value npv rule just as the mm result itself provides no theory of the arrangements under which

energy planning and modern portfolio theory a review abstract modern portfolio theory mpt stands as a widely accepted methodology to meet the challenges associated with the definition of energy planning for a particular territory or region energy planning is thus framed as an investment selection problem mpt is characterized by having a wider capacity and conceptual richness than the other previously used methodologies such as the individual least cost alternative the portfolio approach is based on solving for an objective function that seeks to minimize either the cost or the risk of the portfolio subject to different constraints considering that real electricity generation assets can be defined in terms of cost or return and economic risk for each alternative technology the relevant portfolios are the result of solving the optimization model to determine the efficient cost risk frontier the work presented here consists of an exhaustive review of the literature in relation to the application of mpt methodology to the field of energy planning and electricity production a new classification is proposed from a financial perspective of the selection of investments from the preceding studies it delves deeper into the explanation of the limits to the methodology and into the concept of risk which is key from both a financial and an energy perspective the main methodological contributions found in the literature are examined that are aimed at improving the capacity of the model and adjusting it to the reality of the electricity market finally conclusions are provided from the works analyzed in terms of renewable technologies and the policy implications derived from them in most studies a preference has been shown for the inclusion of renewable technologies in the efficient portfolios however in order to implement the decision to increase the share of renewable technologies greater flexibility in the interconnection capacity between states and in storage capacity is needed

meta analysis of general and partial equilibrium simulations of doha round outcomes quantification of welfare changes due to trade liberalization plays a crucial role for political decision making however significant differences in simulated gains from liberalization do not serve to increase confidence in quantitative assessments based on trade models a meta analysis of trade simulations under the wto doha round is employed to identify model characteristics that influence the magnitude of simulation results findings from a simple regression model are plausible and show that each simulation experiment represents a complex interaction of model characteristics and experimental settings that may not easily be communicated to nonexperts meta analysis proves to be useful for empirically assessing this complexity

managerial incentives and capital management the paper shows how career concerns rather than effort aversion can induce a natural incongruity in risk preferences between managers and superiors a model based on learning about managerial talent is developed to study second best contractual remedies we show that the optimal wage contract is an option of the value of the manager s human capital for insurance reasons and that consequently rationing of capital is often required to counterbalance the manager s resulting incentive to overinvest rationing is strictly superior to price decentralization offering one reason for the prevalence of centralized capital budgeting procedures

can the risks of the kyoto mechanisms be reduced through portfolio diversification evidence from the swedish aij program through joint implementationand the clean development mechanism reductionsof greenhouse gas emissions achieved abroad canbe credited to domestic firms however thetechnical economic and political risksinvolved may prevent the private sector frominvesting in such projects this paperdescribes three types of risks which emissionreduction projects are exposed to eleven pilotprojects carried out under the activitiesimplemented jointly aij program and financedby sweden are evaluated actual project costsare found to exceed projected costs in allcases annual emission reductions also deviatefrom their expected values and vary stronglyover time supporting the hypothesis that suchprojects are risky business the riskmanagement tool portfolio diversification isapplied to a sample of swedish aij projects the results indicate that diversification canreduce the risks of greenhouse gas mitigationprojects significantly thus carbon funds area promising way of lowering the risks of thekyoto mechanisms for private sector investors

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
