sense and no n sense of energy security indicators energy security ranks high on the policy agenda of many countries to improve on energy security governments undertake regulatory measures for promoting renewable energy increasing energy efficiency or curbing carbon dioxide emissions the impacts of such measures on energy security are typically monitored by means of so called energy security indicators in this paper we show that the common use of wide spread energy security indicators falls short of providing a meaningful metric regulatory measures to improve on energy security trigger ambiguous effects across energy security indicators we conclude that a major pitfall of energy security indicators is the lack of a rigorous microeconomic foundation

managing the protection of innovations in knowledge intensive business services abstract how do knowledge intensive business services kibs protect their inventions from imitation by rival firms when choosing among various protection mechanisms data from the 2003 statistics canada innovation survey on services are used to investigate this issue by looking into complementarities substitution and independence among eight protection mechanisms a multivariate probit mvp model is estimated to take into account the fact that kibs simultaneously consider many alternative intellectual property ip protection methods when they attempt to protect their innovations results show that patents registration of design patterns trademarks secrecy and lead time advantages over competitors constitute legal and informal methods that are used jointly these complementarities suggest that ip protection mechanisms that are interdependent and reinforce each other to protect innovations from imitation by rival firms constitute a pattern on which firms rely to protect their innovations from imitation a second pattern is based on the fact that kibs rely on patents and complexity of designs as substitutes and tend to use registration of design patterns and complexity of designs as substitutes in protecting their innovations from imitation a third emerging pattern concerns protection mechanisms that are independent from each other and exhibit no synergy and do not reinforce each other to protect innovations from imitation by other firms

pre empted patents infringed patents and firms participation in markets for technology abstract in recent years firms have increasingly contributed to and been confronted with a patent landscape characterized by numerous but marginal inventions overlapping claims and patent fences as a result firms risk their patent applications to be pre empted or to be infringed upon by rivals while both aspects constitute major challenges for the appropriation of returns to inventive activity extant literature suggests that participation in the market for technology might actually resolve or at least alleviate these problems in this paper we investigate the effect of pre empted and infringed patents on firms engagement in in and cross licensing based on a sample of more than 1100 german manufacturing firms our results show that firms engage in in licensing as a reaction to pre empted patents and in cross licensing if their protected ip was infringed upon however these effects vary depending on the fragmentation of technology fields and whether the firm operates in a discrete or complex product industry

the impact of natural disaster on energy consumption international evidence abstract this research shows that natural disasters may hurt energy consumption by using data on 123 countries over the period 1990 2015 and classifying them according to their economic development level and region based on world development indicators we employ a two step system gmm method to examine the effect of natural disasters on energy consumption presenting findings that support our hypotheses in the models and show a strong negative effect for low income countries or those in the africa region after considering an alternative proxy for natural disaster we implement quantile regression methods their results find that natural disasters exhibit a negative and significant impact on oil renewable and nuclear energy consumptions the quantile regression models used in the robustness check present that the effects are stronger for low level energy consumption economies

a new tailored scheme for the support of renewable energies in developing countries abstract historically the promotion of renewable energy technologies in isolated areas has involved international donors or governments subsidising the initial capital investment this paper proposes an alternative support mechanism for remote villages based on the generation of renewable electricity this communication presents an evaluation of the renewable energy premium tariff rpt scheme a locally adapted variation of the feed in tariff tailored for decentralised grids of developing countries the rpt scheme stimulates the deployment of renewable energy technologies by paying for renewable electricity generated a good quality performance is secured since the support is given based on the electricity produced by renewables not for the initial capital investment the mechanism has been designed to provide a cost effective scheme for the introduction of renewable energy technologies to remote villages to provide sustainable and affordable electricity to local users to make renewable energy projects attractive to policy makers and concurrently decrease financial risk to attract private sector investment

a comparison of oil supply risks in eu us japan china and india under different climate scenarios for many countries the inflow of energy is essential to keep economies running oil is typically considered to be the most critical fuel as an input for the petro chemical and transportation sector and due to limited and less spread reserves in this study external oil supply risks are assessed for the period up to 2035 for the european union united states china japan and india being the five largest importers of oil in the world based on their current supplier portfolio scenarios are constructed for several climate policy and oil supply projections it is found that risks increase strongly when stringent climate policies are prevented from being implemented especially when a peak in oil supply is taken into account resulting in major oil supply disruptions china faces the lowest oil supply risks in most scenarios but the trends of india china and us converge over time due to increasing import dependency of china and india japan faces high risks since the country has the highest oil import dependency combined with a low oil import diversification for the eu all figures are strongly influenced by russia accounting for 32 of total imports and to a lesser extent norway 11 with high overall risks

current account imbalances and financial integration in the euro area abstract while the current account of the euro area as a whole has remained almost balanced in the past two decades several member countries have sizeable deficits or surpluses in this paper we interpret these imbalances as indicators of net capital flows among the euro area countries we distinguish between balances against the euro zone and the rest of the world and examine these for the eu 15 countries we find that for euro members the net flows follow differences in per capita incomes even before the introduction of the euro our results show further that with the introduction of the common currency the elasticity with respect to per capita incomes of net capital flows within the euro area has increased for the members of the euro zone this increase can neither be observed for the flows between the euro members and the rest of the world nor for the flows between the countries that stayed outside the monetary union and the euro zone we interpret this as evidence for increasing financial integration in the euro area there is also some evidence suggesting that the introduction of the euro has led to some financial diversion

real financial market exchange rates and capital flows foreign exchange rates asset prices and capital movements are expected to be closely related to each other as international capital markets become more and more integrated this paper provides new empirical evidence from an index of exchange rate adjusted cross country asset price ratios which may be interpreted as a real effective financial exchange rate the integrated stock flow approach reveals that a country s real effective financial exchange rate is cointegrated with international investors net foreign holdings of its assets the associated error correction equations have useful interpretations against the backdrop of uncovered return parity and investor portfolio rebalancing behavior

us shocks and global exchange rate configurations many academics and observers emphasize that a sharp us dollar depreciation is inevitable for returning the burgeoning us current account deficit to more sustainable levels how may such a us dollar adjustment occur and what may it imply for global exchange rate configurations the paper focuses on the role of us specific economic shocks in the adjustment process and finds that such us shocks have historically exerted a remarkably heterogeneous effect across currencies it shows that this heterogeneity is not only due to policy choices of inflexible exchange rate regimes or to monetary policy but to an important extent is explained by market forces in particular the degree of financial integration foremost in portfolio investment though not by trade this helps explain why it has been in particular the euro and its predecessor currencies as well as other european currencies that have contributed the bulk to the adjustment of the us dollar effective exchange rate over the past 25 years while other flexible currencies have been much less responsive to us shocks the results suggest that currency flexibility is a necessary but not a sufficient condition for achieving a more balanced contribution across currencies to an adjustment of global exchange rate configurations exchange rates are responsive to foreign shocks only to the extent that market mechanisms are in place that make this transmission work which requires in particular that countries have well developed financial markets and are financially integrated these findings have implications for an unwinding of global imbalances and for monetary policy choices and financial market policies in emerging market economies marcel fratzscher

energy security energy modelling and uncertainty the paper develops a framework to analyze energy security in an expected utility framework where there is a risk of disruption of imported energy the analysis shows the importance of an energy tax as a tool in maximizing expected utility and how the level of that tax varies according to the key parameters of the system risk aversion probability of disruption demand elasticity and cost of disruption

complex biofuels related scenarios generated by qualitative reasoning under severe information shortages a review abstract there is a broad spectrum of br biofuel related models however the models are highly specific such models cannot flexibly support complex decision making activities to identify feasible trade offs among many objective functions they represent just one point of view e g engineering company economics therefore cbrms complex biofuel related model are studied in this paper cbrms must cover additional aspects e g macroeconomic ecology sociology and politics such models are inevitably unique partially subjective inconsistent vague and multidimensional ai artificial intelligence has developed a number of tools to solve such problems qualitative reasoning is one of them it is based on the least information intensive quantifiers i e trends there are just three trend qualitative values plus increasing zero constant negative decreasing there are many cbrm items related to soft aspects e g politics taxation etc which cannot be quantified by numbers they are too vague for example if the political sociological sensitivity of land ownership is increasing then the cost of biofuels is increasing such verbal knowledge item cannot be incorporated into a traditional numerical model the paper describes developments of cbrms based on expert knowledge and common sense a consensus among experts is often not reached because of substantial subjectivity of experts knowledge a qualitative intersection of cbrms developed by several experts is simple the case study presents a model based on integration of 10 heuristics using 9 variables e g refinery capacity cost of biofuel production and biofuel demand the result is represented by 13 scenarios the paper is self contained no a prior knowledge of qualitative models is required

analysis of energy embodied in the international trade of uk interest in the role embodied energy plays in international trade and its subsequent impact on energy security has grown as a developed nation the uk s economic structure has changed from that of a primary producer to that of a primary consumer although the uk s energy consumption appears to have peaked it imports a lot of energy embodied in international trade alongside the more obvious direct energy imports the uk has seen increasing dependency on imported fossil energy since the uk became a net energy importer in 2005 in this paper an energy input output model is established to calculate not only the amount of fossil energy embodied in uk s imports and exports but also the sector and country distributions of those embodied fossil energy the research results suggest the following uk s embodied fossil energy imports have exceeded embodied fossil energy exports every year since 1997 uk embodied energy imports through the so called made in china phenomena are the largest accounting for 43 of total net fossil energy imports if net embodied fossil energy imports are considered the gap between energy consumption and production in uk is much larger than commonly perceived with subsequent implications to the uk s energy security

financial integration and the wealth effect of exchange rate fluctuations abstract recent years have witnessed a large increase in international financial integration in the form of largely offsetting cross holdings across countries we assess how such financial leverage affects the international transmission of monetary shocks and find that it leads to sizable welfare differentials that far exceed the impact due to nominal rigidities we document the relevance of the exact nature of holdings with bond holdings associated with larger effects than equity holdings the impact of financial leverage on welfare is also sensitive to the extent of exchange rate pass through and the substitutability between goods produced in different countries

price stability with imperfect financial integration this paper studies whether the international monetary system can be affected by asymmetries in the cross country positions in the international financial markets i e the fact that some countries are large debtors while others are creditors an important channel that is explored is the interaction between international risk sharing and the stabilization role of monetary policy in each country the main finding is that the welfare costs of incomplete markets and the gains of deviating from a policy of price stability are increasing with the cross country asymmetries in the initial net international positions and in particular they become nonnegligible when the persistence of the shocks increases 1 of a permanent shift in steady state consumption for the welfare costs of incomplete markets and 0 2 for the gains of deviating from a policy of price stability when global imbalances become larger optimal monetary policy requires an increase in the volatilities of the real returns on assets and in particular of the nominal interest rates which should happen to be more correlated across countries

do trade costs in goods market lead to home bias in equities abstract two of the main puzzles in international economics are the consumption and the portfolio home biases we solve for international equity portfolios in a two country two good stochastic equilibrium model with trade costs in goods markets we show that introducing trade costs as suggested by obstfeld and rogoff obstfeld m rogoff k 2000a the six major puzzles in international macroeconomics is there a common cause nber macroeconomics annual 15 is not sufficient to explain these two puzzles simultaneously on the contrary we find that trade costs create a foreign bias in portfolios for reasonable parameter values this result is robust to the addition of non tradable goods for standard calibrations of the preferences

will there be a dollar crisis almost everyone believes that the us current account deficit must eventually end and that this end will involve dollar depreciation however many believe that this depreciation will take place gradually this paper shows that any process of gradual dollar decline fast enough to prevent the accumulation of implausible levels of us external debt would impose capital losses on investors much larger than they currently expect as a result there will at some point have to be a wile e coyote moment a point at which expectations are revised and the dollar drops sharply it is much less clear however whether this crisis will produce macroeconomic problems paul krugman

ideas for rent an overview of markets for technology this article surveys some of the recent literature on technology markets and summarizes its main issues and insights we structure our analysis in three parts the supply and demand of technology the factors that condition the formation and growth of technology markets industry structure and dynamic issues in addition we summarize some of the studies that have tried to document the size and growth of these markets we find that the literature has focused mainly on the supply of technology but several other aspects of these markets remain under studied including the demand for external technology the role of uncertainty in technology markets and the dynamic interaction between industry structure and the market for technology understanding these will illuminate whether markets for technology will continue to grow or remained confined to pockets of the economy copyright 2010 the author 2010 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

segmentation and time of day patterns in foreign exchange markets abstract this paper sheds light on a puzzling pattern in spot foreign exchange markets domestic currencies appreciate depreciate systematically during foreign domestic working hours this phenomenon spans many years and several exchange rates and overrides calendar effects we argue that it is mainly due to liquidity and inventory patterns that emerge from the combination of two factors domestic agents tend to be net buyers of foreign currency and to trade mostly in their country s working hours the prevalence of domestic foreign traders demanding the counterpart currency during domestic foreign working hours implies sell price buy price pressure on the domestic currency during domestic foreign working hours

agricultural biotechnology s complementary intellectual assets we formulate and test a hypothesis for the dramatic restructur ing that the plant breeding and seed industry has recently undergone the reorganization can be explained in part by the desire to exploit comple mentarities between intellectual assets needed to create genetically mod ified organisms this hypothesis is tested using data on agricultural biotechnology patents notices for field tests of genetically modified organisms and firm characteristics the presence of complementarities is identified with a positive covariance in the unexplained variation of asset holdings results indicate that coordination of complementary assets has increased under the consolidation of the industry ne of the central problems in the economics of inno vation concerns how industries change as they absorb fundamental research breakthroughs rarely has change been more pronounced than in agriculture following the introduction of recombinant dna technology and affiliated techniques of genetic engineering by offering breeders the ability to alter plant traits by directly manipulating se quences of genetic code tools of agricultural biotechnology change the possibilities for crop improvement profoundly the new techniques enhance the speed and precision of agricultural research and development r d while ex panding the space of potential new products seed firms now offer farmers crop varieties embodying new ap proaches for controlling pests managing physical stresses on plants increasing crop yields and growing differenti ated quality enhanced crops concurrent with these technical changes in the r d process the agricultural inputs industry has over the past two decades witnessed a comprehensive restructuring sev eral large chemical firms including monsanto dow and dupont moved aggressively into plant biotechnology mak ing huge investments in the life sciences as newly minted agronomic systems companies these firms acquired all of the large national seed firms in north america including pioneer dekalb asgrow garst and others meanwhile the research intensive agricultural biotechnology sector from its appearance in the 1980s as a large set of small startup firms had by the end of the 1990s already reached a second stage with most of the startups either folded or acquired by the new agronomic systems giants the industry s consoli dation was surprising not only for its rapid pace and com prehensive scope but also for the extremely high valuations at which some firms were acquired in 1997 for example monsanto acquired holdens foundation seeds of wil liamsburg iowa together with two marketing subsidiaries for 1 02 billion 25 times the annual sales of the mature privately held firm whose revenues derived entirely from the breeding and distribution of corn seed the emergent industry structure with a relatively small number of tightly woven alliances each organized around a major life sciences firm each vertically integrated from basic r d through to marketing stands in contrast to the more diffuse structure of twenty years ago this structure is likewise noteworthy when one considers trends in other research intensive fields the pharmaceutical biotechnology industry for example maintains a large number of free standing firms specializing in r d and earning revenues through various licensing agreements majewski 1998 hall and ziedonis 2001 observe that the u s semiconduc

the settlement of patent litigation in this article i develop a model to analyze patent licensing that is induced as part of a settlement agreement to avoid litigation of the issue of patent validity the patentee possesses private information about patent validity and makes a take it or leave it settlement offer to a single potential rival an essentially unique sequential equilibrium exists if out of equilibrium beliefs are restricted appropriately the model analyzes the effect of the probability of settlement and litigation

security of supply and retail competition in the european gas market some model based insights in this paper we analyze the impact of uncertain disruptions in gas supply upon gas retailer contracting behavior and consequent price and welfare implications in a gas market characterized by long term gas contracts using a static cournot model in order to most realistically describe the economical situation our representation divides the market into two stages the upstream market that links by means of long term contracts producers in exporting countries russia algeria etc to local retailers who bring gas to the consuming countries to satisfy local demands in the downstream market disruption costs are modeled using short run demand functions first we mathematically develop a general model and write the associated kkt conditions then we propose some case studies under iso elasticity assumptions for the long short run inverse demand curves in order to predict qualitatively and quantitatively the impacts of supply disruptions on western european gas trade in the second part we study in detail the german gas market of the 1980s to explain the supply choices of the german retailer and we derive interesting conclusions and insights concerning the amounts and prices of natural gas brought to the market the last part of the paper is dedicated to a study of the bulgarian gas market which is greatly dependent on the russian gas supplies and hence very sensitive to interruption risks some interesting conclusions are derived concerning the necessity to economically regulate the market by means of gas amounts control if the disruption probability is high enough

fee versus royalty licensing in a cournot duopoly model abstract this paper finds that royalty licensing can be superior to fixed fee licensing for the patent holding firm when the cost reducing innovation is non drastic the reason for this result is that the patent holding firm enjoys a cost advantage over the licensee under royalty licensing while the two firms compete on equal footing under fixed fee licensing

techno economic evaluation of small hydro power plants in greece a complete sensitivity analysis abstract hydropower has by far been the most mature renewable energy resource used for electricity generation in our planet recently the investors interest was whipped up by the mass development of small hydropower shp stations as they are the most prosperous for additional hydropower penetration in developed electricity markets in greece the increasing interest for building shp stations got off the ground since 1994 ever since an enormous number of requests keep piling up in the greek regulatory authority of energy and the ministry of development with the object of creating new shp stations of total capacity over 600 mw the present work is concentrated on the systematic investigation of the techno economic viability of shp stations the study is concluded by a sensitivity analysis properly adapted for the local market financial situation in order to enlighten the decision makers on the expected profitability of the capital to be invested according to the results obtained the predicted internal rate of return irr values are greater than 18 for most shp cases analysed finally as per the sensitivity analysis carried out the installation capacity factor the local market electricity price annual escalation rate and the reduced first installation cost are found to be the parameters that mostly affect the viability of similar ventures

motives to patent empirical evidence from germany abstract against the background of the patent upsurge we first analyse the role of patenting and alternative instruments to protect intellectual property based on a sample of german companies active in patenting in a second step we investigate the motives to patent considering sector and company size effects we find that company size matters both for the importance of instruments and the motives to patent especially important are the new strategic motives to patent like using patents to improve a company s own position in negotiations with partners licensees and the financial sector or to use patents as incentives for r d personnel or performance indicators these correlate positively with company size we derive some possible challenges for future patent policies from these insights

the long or short of it determinants of foreign currency exposure in external balance sheets abstract a major focus of the recent literature on the determination of optimal portfolios in open economy macroeconomic models has been on the role of currency movements in determining portfolio returns that may hedge various macroeconomic shocks however there is little empirical evidence on the foreign currency exposures that are embedded in international balance sheets using a new database we provide stylized facts concerning the cross country and time series variation in aggregate foreign currency exposure and its various subcomponents in panel estimation we find that richer more open economies take longer foreign currency positions in addition we find that an increase in the propensity for a currency to depreciate during bad times is associated with a longer position in foreign currencies providing a hedge against domestic output fluctuations we view these new stylized facts as informative in their own right and also potentially useful to the burgeoning theoretical literature on the macroeconomics of international portfolios

the effect of fossil energy and other environmental taxes on profit incentives for change in an open economy evidence from the uk this paper argues that the underlying supply and demand analysis of fossil energy and other environmental taxes needs further elaboration when a country a introduces national fossil energy or environmental taxes and b is open to international trade at given world prices we provide evidence that such conditions are plausible for many sectors in the uk a key implication is that the short run effects of such taxes should not be felt in final good prices since these are determined in world markets but in terms of underlying profitability these changes in underlying profits provide two key incentives for producers to change to more environmentally friendly production techniques and to switch resources to production of less environmentally harmful goods using input output techniques we provide evidence for the uk to show how existing fossil energy and other green taxes have affected underlying profitability the evidence shows quite strong profit incentives to shift resources from a small number of energy intensive industries to others

the six flaws of the eurozone when it was created it was reasonable to think that the architecture of the monetary union was not perfect it was also likely that the imperfections would lead to difficulties possibly even crises this article identifies six flaws most of which had been identified even before the launch of the euro it starts by pinpointing why the eurozone a bold and unprecedented experiment is inherently fragile it is not conducive to the convergence of national inflation rates it is not an optimum currency area and it is not a federal state taking these characteristics as given the article argues that the eurozone needs to address their implications it observes that it has not been the case so far hence the six flaws fiscal discipline has not been achieved the need for a banking union which has finally been recognized and only partly implemented the ecb is not a complete and fully independent central bank some member countries need a sovereign debt relief structural reforms are badly needed but intrusiveness cannot be the solution the governance of the eurozone is not designed for crisis management

capital inflows and euro area long term interest rates abstract capital flows into the euro area were particularly large in the mid 2000s and the share of foreign holdings of euro area securities increased substantially between the introduction of the euro and the outbreak of the global financial crisis we show that the increase in foreign holdings of euro area bonds in this period is associated with a reduction of euro area long term interest rates by about 1 55 percentage points which is in line with previous studies that document a similar impact of foreign bond buying on us treasury yields these results are relevant both from a euro area and a global perspective as they show that the phenomenon of lower long term interest rates due to foreign bond buying is not exclusive to the united states and foreign inflows into euro area debt securities may have added to increased risk appetite and hunt for yield at the global level

external adjustment and the global crisis abstract the period preceding the global financial crisis was characterized by a substantial widening of current account imbalances across the world since the onset of the crisis these imbalances have contracted to a significant extent in this paper we analyze the ongoing process of external adjustment in advanced economies and emerging markets we find that countries whose pre crisis current account balances were in excess of what could be explained by standard economic fundamentals have experienced the largest contractions in their external balance we subsequently examine the contributions of real exchange rates domestic demand and domestic output to the adjustment process allowing for differences across exchange rate regimes and find that external adjustment in deficit countries was achieved primarily through demand compression rather than expenditure switching finally we show that changes in other investment flows were the main channel of financial account adjustment with official external assistance and ecb liquidity cushioning the exit of private capital flows for some countries

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

long term energy services security what is it and how can it be measured and valued abstract the paper reviews some recent approaches towards measuring the extent of long term energy security and security externality valuation it starts out to discuss the contextual connotations of notions of energy security in medium to long term time frames and reviews some indicators that have been proposed to quantify it special attention is paid to two of these approaches which the authors helped to develop i e diversity based indices and the supply demand index the paper takes issue with conventional welfare economic approaches that neglect i the scope on the demand side for raising security and ii negative feedback mechanisms of socio political impacts of international rent transfers in fossil fuels exporting countries the concept of energy services security is proposed with a demand side focus this enables application of an integrated approach to gauge the resilience of a society to meet the needs of its population for energy services over longer timescales ahead from various interrelated perspectives propositions are made on the attribution of security externalities to the use of fossil fuels policies and suggestions for further improvements of measures for energy services security

the external wealth of nations measures of foreign assets and liabilities for industrial and developing countries abstract although capital flows are closely monitored surprisingly little is known about the accumulated stocks of foreign assets and liabilities held by various countries especially in the developing world this paper constructs estimates of foreign assets and liabilities and their equity and debt subcomponents for a sample of 67 industrial and developing countries it characterizes the stylized facts of international balance sheets and asks whether there are trends in net foreign asset positions and shifts in debt equity ratios over time finally it explores the sensitivity of estimated stock positions to the treatment of valuation effects not captured in balance of payments data

exploring renewable energy pricing with analytic network process comparing a developed and a developing economy abstract increasing use of renewable sources has a vital importance in mitigating increasing energy demand and global warming the limited reserves and negative environmental impacts associated with fossil fuel consumption make the renewable energy sources considerable alternatives in case environmental externalities are taken into consideration pricing models for renewable energy alternatives are commonly based on the same fundamentals as the fossil fuels but this approach neglects some of the characteristics that are unique to renewable energy alternatives in order to develop more accurate pricing models these unique variables which are mostly considered as market externalities need to be integrated in the current forms of pricing models the originality of this work is its ability to combine social technical environmental and economic aspects using analytic network process in order to provide a more holistic point of view on factors impacting renewable energy pricing through a comparison of two case studies united states u s and turkey are the two cases analyzed in this paper u s represents a developed economy whereas turkey represents a developing economy it is expected that the results of this work would be helpful for further research in understanding the dynamics behind pricing mechanism of the renewable sources in different environments for instance fundamental differences in relative importance of pricing factors between two case countries have been identified as different levels of enforcement through laws and regulations impact of geographic characteristics on site selection and job opportunities created through new investments

the economics of product patents this paper develops a model of product patents in which the patent changes the nature of market entry behavior rather than preventing entry entirely the model incorporates three levels of action namely the innovator s patenting decision the potential entrant s location decision and possible court action the analysis demonstrates how the characteristics of the patents system and the enforcement framework can influence rivals variety choices and thus the market equilibrium it also considers how the system can in principle be adjusted to improve social welfare copyright 1990 by american economic association

europe and global imbalances although europe in the aggregate is not a major contributor to global current account imbalances its trade and financial linkages with the rest of the world mean that it will still be affected by a shift in the current configuration of external deficits and surpluses we assess the macroeconomic impact on europe of global current account adjustment under alternative scenarios emphasizing both trade and financial channels finally we consider heterogeneous exposure across individual european economies to external adjustment shocks philip r lane and gian maria milesi ferretti

distribution of costs induced by the integration of res e power this article focuses on the distribution of costs induced by the integration of electricity generation from renewable energy sources res e the treatment to distribute these costs on different market actors is crucial for its development for this purpose individual actors of electricity markets and several cost categories are identified according to the defined cost structure possible treatments to distribute the individual cost categories on different relevant actors are described finally an evaluation of the cost distribution treatments based on an economic analysis is given economic efficiency recommends that clearly attributable shallow grid connection as well as deep grid costs are charged to the corresponding res e producer and that the res e producers are also charged the regulating power costs however deep grid integration costs should be updated to reflect evolving scarcities also regulating power costs should reflect actual scarcity and thus be symmetric and based on real time prices taking into account the overall system imbalance moreover the time span between the closure of the spot market and actual delivery should be chosen as short as possible to enable accurate res e production forecasts

country portfolios in open economy macro models this paper develops a simple approximation method for computing equilibrium portfolios in dynamic general equilibrium open economy macro models the method is widely applicable simple to implement and gives analytical solutions for equilibrium portfolio positions in any combination or types of asset it can be used in models with any number of assets whether markets are complete or incomplete and can be applied to stochastic dynamic general equilibrium models of any dimension so long as the model is amenable to a solution using standard approximation methods we first illustrate the approach using a simple two asset endowment economy model and then show how the results extend to the case of any number of assets and general economic structure

assessing the sustainability of external imbalances in the european union we assess the sustainability of the current account ca balance net international investment position niip and net external debt ned in a sample of 22 eu countries using two complementary approaches first we employ time series stationarity tests of current account balance to gdp ratios as well as cointegration tests of exports and imports of goods and services second we assess the level of trade balance that stabilises the niip and the ned we find that there is sustainability of the ca balance in eight countries niip in five countries and ned in 10 countries whereas there is evidence of a lack of sustainability in five debtor nations and three creditor nations both approaches are consistent with each other given the relationship between flows and stocks the existence of structural breaks and valuation effects via exchange rate and interest rate changes

alternative framework for renewable energy planning in the philippines abstract like many countries striving to be responsible consumers of energy and conscious of the need to mitigate the impact of climate change the philippines has in both policy and practice shown a bias towards renewable energy re sources the country s proportion of re production in primary energy and distribution in electricity is significantly higher than those of many asian and european countries however the philippine national re program has adopted a strategy of aggressively amassing re capacity to the extent of tripling the capacity over the period 2011 to 2030 the preoccupation with more megawatts rather than the value of re beyond clean energy has erected a bias against off grid re applications off grid re applications can displace more expensive diesel generation and can enhance the livelihood opportunities for communities the insistence on focusing on megawatts is threatening to bloat the current feed in tariff structure by causing large grid connected applications to be seriously oversubscribed this paper reviews the current re status in the philippines and presents a simple alternative planning paradigm in which the ability of re technology to affect the livelihood of the residents and the effectiveness of its energy delivery are used to distinguish the utility of different re technologies in off grid and grid connected areas the authors also describe an actual kw scale off grid application that addresses both energy and economic poverty

exchange rate misalignments in duopoly the case of airbus and boeing we examine the effect of exchange rate misalignments on competition in the market for large commercial aircraft this market is a duopoly where players compete in dollar denominated prices while one of them airbus incurs costs mostly in euros we construct and calibrate a simulation model to investigate how companies adjust their prices to deal with the effects of a temporary misalignment and how this affects profit margins and volumes we also explore the effects on the long run dynamics of competition we conclude that due to the duopolistic nature of the aircraft market airbus will pass only a small part of the exchange rate fluctuations on to customers through higher prices moreover due to features specific to the aircraft industry such as customer switching costs and learning by doing even a temporary departure of the exchange rate from its long run equilibrium level may have permanent effects on the industry

international currency exposures valuation effects and the global financial crisis abstract we examine the evolution of international currency exposures with a particular focus on the 2002 12 period during the run up to the global financial crisis there was a widespread shift towards positive net foreign currency positions such that relatively few countries exhibited the archetypal emerging market short foreign currency position on the eve of the global financial crisis during the crisis the upheaval in currency markets generated substantial currency generated valuation effects much of which were not reversed there is some evidence that the distribution of valuation effects was stabilizing in the sense of showing a negative covariation pattern with pre crisis net foreign asset positions
