public prioritisation of energy affordability in the uk much research has focused on the so called energy trilemma i e three leading energy policy issues energy security affordability and climate change mitigation whilst substantial understanding exists of why people support climate friendly energy policies little is known about why they think affordability is important particularly what leads members of the public to identify this policy goal as more important than other objectives here we examine this question via a nationally representative survey of 2441 uk residents and demonstrate that concerns about personal costs explain a small amount of variation in the prioritisation of affordability as an energy policy goal a range of other factors also significantly contribute one such factor is beliefs about who is responsible for energy transitions these findings suggest policy actions to address affordability concerns should go beyond energy prices and include additional considerations such as distributive justice and equality

debt bargaining and credibility in firm supplier relationships abstract we examine optimal leverage for a downstream firm relying on implicit self enforcing contracts with a supplier performing a leveraged recapitalization prior to bargaining increases the firm s share of total surplus however the resulting debt overhang limits the range of credible bonuses resulting in low input quality optimal financial structure trades off bargaining benefits of debt with inefficiency resulting from overhang consistent with empirical evidence the model predicts that leverage increases with supplier bargaining power e g unionization rates and decreases with utilization of non verifiable inputs e g human capital

price stability in open economies this paper studies the conditions under which price stability is the optimal policy in a two country open economy model with imperfect competition and price stickiness special conditions on the levels of country specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied these restrictions apply to both cooperative and non cooperative settings most importantly we show that cooperative and non cooperative solutions do not coincide despite market completeness and producer currency pricing in this framework our analysis suggests a role for international policy coordination

tax disturbances and real economic activity in the postwar united states abstract this paper investigates the macroeconomic effects of cyclical fluctuations in marginal tax rates it finds that systematically including tax variables in a standard real business cycle model substantially improves the model s ability to reproduce basic facts about postwar u s business cycle fluctuations in particular modeling fluctuations in personal and corporate income tax rates increases the model s predicted relative variability of hours and decreases its predicted correlation between hours and average productivity fluctuations in tax rates produce large substitution effects that alter the leisure labor supply decision

human capital bankruptcy and capital structure we derive a firm s optimal capital structure and managerial compensation contract when employees are averse to bearing their own human capital risk while equity holders can diversify this risk away in the presence of corporate taxes our model delivers optimal debt levels consistent with those observed in practice it also makes a number of predictions for the cross sectional distribution of firm leverage consistent with existing empirical evidence it implies persistent idiosyncratic dierences in leverage across firms an important new empirical prediction of the model is that ceteris paribus firms with more leverage should pay higher wages

new frontiers and conceptual frameworks for energy justice this article explores how concepts from justice and ethics can inform energy decision making and highlight the moral and equity dimensions of energy production and use it defines energy justice as a global energy system that fairly distributes both the benefits and burdens of energy services and one that contributes to more representative and inclusive energy decision making the primary contribution of the article is its focus on six new frontiers of future energy justice research first is making the case for the involvement of non western justice theorists second is expanding beyond humans to look at the rights of nature or non anthropocentric notions of justice third is focusing on cross scalar issues of justice such as embodied emissions fourth is identifying business models and the co benefits of justice fifth is better understanding the tradeoffs within energy justice principles sixth is exposing unjust discourses in doing so the article presents an agenda constituted by 30 research questions as well as an amended conceptual framework consisting of ten principles the article argues in favor of justice aware energy planning and policymaking and it hopes that its reconsidered energy justice conceptual framework offers a critical tool to inform decision making

competitive depreciation and the role of distorting taxes in an interdependent economy abstract this paper investigates the manners in which international cooperation in monetary policies affects the rate of inflation in a two country sticky price model within reasonable parameter values international monetary coordination increases the steady state inflation for given tax policies when the tax regime is endogenously chosen however self oriented monetary policies can engage in competitive depreciation and induce a higher average inflation than the first best inflation rate

international monetary policy coordination and competitive depreciation a reevaluation is there a need for international coordination of monetary policies within the current system of floating exchange rates in a recent paper obstfeld and rogoff 1995 argue that in an environment of sticky prices under floating exchange rates monetary policy shocks will generate positive welfare spillovers across countries this leads to the conclusion that international monetary policy coordination is unnecessary and may in fact be undesirable since it nurtures a bias towards high inflation our paper shows that these conclusions are dependent on the manner in which prices are set when firms engage in pricing to market ptm setting prices in the currency of the buyer monetary policy tends to have negative welfare spillovers this gives an incentive to engage in competitive depreciation in a noncooperative equilibrium world inflation will be higher the greater the importance of ptm with a high degree of ptm it follows that the case for international monetary policy coordination is restored if ptm is at an intermediate range however international monetary coordination may have no consequences at all

monetary policy cooperation may not be counterproductive this paper qualifies rogoff s famous 1985 result that international monetary policy cooperation is counterproductive in a model similar to his it is shown that if wage setters are non atomistic and inflation averse as policymakers are cooperation leads to higher employment and possibly lower inflation

new directions for stochastic open economy models the paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages explicit solution of the wage setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare expected output and the expected terms of trade despite the potential interplay between imperfections due to sticky wages and monopoly the optimal monetary policy rule has a closed form solution to motivate our model we show that observed correlations between terms of trade and exchange rates are more consistent with our traditional assumptions about nominal rigidities than with a popular alternative based on local currency pricing 2000 elsevier science b v all rights reserved

exploring participatory energy budgeting as a policy instrument to foster energy justice abstract the ethical and sustainable production and consumption of energy are becoming increasingly important with the ongoing transformation and decentralization of the energy system for other kinds of goods and commodities ethical consumption have direct implications for and the participation of informed citizens due to its intangibility energy lacks the same levels of reflection and intervention by citizens and those aspects are yet to be fully explored in practice this paper contributes to the understanding of how energy justice might be approached we reflect on an empirical experience of participatory energy budgeting a process aimed at determining how to redistribute a share of energy linked to collective virtuous consumption behaviors we analyze through a qualitative thematic analysis how participants make sense of the participatory energy budgeting process and the emerged dynamics within the local communities and how this process can strive to reconfigure the relationship among civil society the energy sector and politics in order to remediate injustices we highlight how the construction in practice of energy justice in a local community might be closely linked to issues such as the form of energy governance that allows for the participation of citizens and the accountability of the process policies and technological limitations

the role of consumption substitutability in the international transmission of monetary shocks abstract this paper develops a general framework to analyze the impact of monetary shocks in an open economy focusing on the role of the degree of substitutability between goods produced in different countries we extend the contributions by obstfeld and rogoff obstfeld m rogoff k 1995 exchange rate dynamics redux journal of political economy 103 624 659 and corsetti and pesenti corsetti g pesenti p 1997 welfare and macroeconomic interdependence nber working paper 6307 to show that the welfare impact differs across countries when the degree of substitutability between goods produced in different countries is different from the degree of substitutability between goods produced in the same country a shock that would be beneficial in a closed economy can have an adverse beggar thyself effect in the country where it takes place or an adverse beggar thy neighbor effect on its neighbor

measuring the temporal dynamics of policy mixes an empirical analysis of renewable energy policy mixes balance and design features in nine countries abstract complex societal or environmental problems require fast and substantial socio technical transitions for instance in the case of climate change these transitions need to take place in the energy transport and several industry sectors to induce and accelerate such transitions numerous policy interventions are required which interact with each other in policy mixes while several conceptual studies on policy mixes have been published recently there is very little empirical research apart from single case or small n studies it has been prominently argued that the debate about policy mixes has reached an impasse partly due to this lack of empirical work this paper addresses this gap by providing a first analysis of the temporal dynamics of complex policy mixes to do so we develop a conceptualization and measurement of policy mix balance across instrument types as well as policy mix design features in the form of intensity as a general and technology specificity as a technology focused design feature this allows us to answer the question how temporal dynamics of policy mixes differ between countries regarding their balance and design features our measurement approach is developed bottom up i e policies are assessed individually and then aggregated systematically at the policy mix level this enables overcoming the dependent variable problem in the study of policy change i e the problem of measuring policy output more specifically we develop a comparative dataset of 522 renewable energy policies in nine oecd countries our analysis shows that countries policy mix dynamics vary strongly regarding some variables e g technology specificity but less regarding others e g balance as a validity check we also test the effects of these mix dynamics on policy outcome in the form of renewable energy technology diffusion we reflect our findings in light of the theoretical debates around policy mixes and policy design and discuss how our results provoke an agenda for the new generation of research on policy mixes we specifically discuss avenues for future research with a particular focus on the politics of policy mixes

in pursuit of energy justice abstract energy justice provides a framework to perceive disparities in our energy system the foundation of energy justice draws heavily from the environmental justice movement grounded in larger issues of representation economic relations between the state firms and social groups this article draws from the environmental justice movement to explore concepts of universal and particular justice universal energy justice holds to values stemming from judicial and philosophical groundings based in procedural distributional and cosmopolitan justice issues particular energy justice relies on recognition justice of cultural and environmental factors influencing choices around energy technologies and policy preferences for the distribution of energy services empirically this article examines tensions within the energy system in the european union it does this in two areas first by examining how universal energy justice is spread through national regulatory authorities nras dealing with energy second particular energy justice is exemplified by a political solution to energy poverty in bulgaria rather than a regulatory response this contrasts with a western european approach the aim of the article is to show the pursuit of energy justice attempts to resolve tensions between groups and differing politics to both access and provide energy services

practices and imaginations of energy justice in transition a case study of the noordoostpolder the netherlands abstract renewable energy technologies are often idealized as environmentally innocent alternatives to fossil fuels fossil fuel extraction is often considered as unjust and renewable energy as the just alternative at the same time renewable energy projects such as wind parks are often resisted because of the uneven impacts of its infrastructure this paper analyses such ambiguous meanings of energy justice social justice issues related to energy along the lines of its three tenets distributional procedural and recognition justice aiming to understand how energy justice is constructed from below it does so on the basis of a case study in the noordoostpolder the netherlands where plans for extracting shale gas went together with both large scale and small scale renewable energy practices the paper analyses how energy justice is made by how people resist shale gas and engage in renewable energy practices and as such produce new imaginations and normativities of energy justice such an ethnographic approach helps to understand energy justice as a process of co construction of activists policy makers and scholars and as such responds to recent calls for a human centred approach to the study of energy transitions the paper is based on two and a half years of ethnographic fieldwork in the noordoostpolder

sunk investment bargaining and choice of capital structure this paper shows how a firm might optimally choose debt to affect the outcome of bilateral bargaining with workers or other input suppliers it is shown that debt may alleviate the well known underinvestment problem associated with the inability to write precommitment contracts also in such circumstances debt could be pareto improving over complete equity financing the relationship between the optimal level of debt and asset specificity of investment and bargaining power of the firm vis a vis the workers is explored the williamson conjecture that higher asset specificity will lead to less debt is shown not to be valid in general

fuel poverty excess winter deaths and energy costs in vermont burdensome for whom energy whether from electricity natural gas heating oil propane kerosene or wood is essential for the well being of many americans yet those who spend more than 10 percent of their income of energy services can be considered fuel poor this study assesses the extent and severity of fuel poverty in vermont it analyzes energy burdens in vermont by household income deciles using data from the census bureau s american community survey approximately 71 000 people suffered from fuel poverty in vermont in 2000 and in 2012 the number rose to 125 000 or one in five vermonters startlingly fuel poverty grew 76 percent during this period excess winter deaths caused potentially by fuel poverty kill more vermonters each year than car crashes the article then provides 12 policy recommendations based on a small sample of elite semi structured research interviews these include suggestions that the vermont legislature better fund investments in weatherization among low income households that community groups and social service agencies scale up the training of energy efficiency coaches that state agencies endorse improvements in housing efficiency and appropriate fuel switching and that utilities and fuel providers offer extra assistance for disconnected households and allow for on bill financing of efficiency improvements

attributing responsibility for energy justice a case study of the hinkley point nuclear complex since 2006 as part of the transition to low carbon technologies uk energy policy has moved towards incentivising new nuclear power production as a result the uk has developed a now delayed strategy to deliver around 16gw of new nuclear power by 2030 this policy context provides an opportunity to reflect not only on the material infrastructure needed to meet transition targets but also on who is responsible for the energy justice implications of these decisions using data collected from 26 semi structured interviews with ngo and policy representatives this paper presents a case study of energy justice concerns surrounding the hinkley point nuclear complex in somerset focusing particularly on the highly controversial hinkley point c developments the results emphasise the importance of considering not only instances of energy justice or injustice but of attributing responsibility for them a concept that has been largely overlooked in the energy justice literature ngos government and business allocate responsibility differently in nuclear energy decision making we find that perceptions of responsibility are highly dependent upon the level of transparency in decision making this article is part of a virtual special issue entitled exploring the energy justice nexus

inflation stabilization and welfare the case of a distorted steady state this paper considers the appropriate stabilization objectives for monetary policy in a microfounded model with staggered price setting rotemberg and woodford 1997 and woodford 2002 have shown that under certain conditions a local approximation to the expected utility of the representative household in a model of this kind is related inversely to the expected discounted value of a conventional quadratic loss function in which each period s loss is a weighted average of squared deviations of inflation and an output gap measure from their optimal values zero however those derivations rely on an assumption of the existence of an output or employment subsidy that offsets the distortion due to the market power of monopolistically competitive price setters so that the steady state under a zero inflation policy involves an efficient level of output here we show how to dispense with this unappealing assumption so that a valid linear quadratic approximation to the optimal policy problem is possible even when the steady state is distorted to an arbitrary extent allowing for tax distortions as well as market power and when as a consequence it is necessary to take account of the effects of stabilization policy on the average level of output we again obtain a welfare theoretic loss function that involves both inflation and an appropriately defined output gap though the degree of distortion of the steady state affects both the weights on the two stabilization objectives and the definition of the welfare relevant output gap in the light of these results we reconsider the conditions under which complete price stability is optimal and find that they are more restrictive in the case of a distorted steady state we also consider the conditions under which pure randomization of monetary policy can be welfare improving and find that this is possible in the case of a sufficiently distorted steady state though the parameter values required are probably not empirically realistic

the macroeconomic effects of monetary and fiscal policy in a small open economy does the exchange rate regime matter abstract this paper develops a small open economy model in the spirit of obstfeld and rogoff 1995 the introduction of endogenous traded sector output unlocks current account and real exchange rate effects within this framework where specific consideration is given to the case with fixed but adjustable parities exchange rate devaluation generates similar qualitative effects as a money supply expansion under floating rates output and external effects of government spending shocks are broadly consistent with the adjusted basic non micro founded mundell and fleming mf framework but differ in significant ways from the baseline mf model contrary to the textbook mf model a government expenditure shock depreciates the nominal exchange rate and generates real effects under the fixed rate system

unequal resilience the duration of electricity outages abstract the resilience of social biophysical and technological systems is of increasing scholarly and practical import guided by scholarship on disaster resilience environmental inequality and urban service inequality we advance the study of unequal resilience in a critical infrastructure the electric grid we analyze inequality in electricity outage duration at the census block group level using data from the u s census the u s geological survey and a u s electrical utility s database of power outages from 2002 to 2004 our intersectional approach identifies a factor variable of american indian disadvantage as a correlate of average outage duration suggesting possible support for an institutional bias hypothesis however spatial error regression models demonstrate that unequal resilience within our study area is most consistently explained by proximity to priority assets i e hospitals average downstream customers affected by outages and environmental conditions i e the seasonality of outages these results are consistent with existing research on utilities response to power outages and more broadly with the bureaucratic decision rules perspective on service inequalities we discuss the implications of our findings for future research and energy policy

optimal capital structure bargaining and the supplier market structure abstract this paper studies the relationship between firm leverage and supplier market structure we find that firm leverage decreases with the degree of competition between suppliers specifically leverage decreases with the elasticity of substitution between suppliers leverage also decreases with the number of suppliers when the elasticity of substitution is high and increases with the number of suppliers when the elasticity is low we also provide empirical evidence that is consistent with the model predictions

on the sign of the investment uncertainty relationship understanding the effects of uncertainty over any decision variable has fascinated economists for a long time risk aversion and incomplete markets are likely to make the investment uncertainty relationship negative e g roger craine 1989 joseph zeira 1989 what happens in the absence of risk aversion and incomplete markets is however ambiguous richard hartman 1972 and andrew b abel 1983 1984 1985 found that in the presence of symmetric convex costs of adjustment mean preserving increases in price uncertainty raise investment of a competitive firm as long as the profit function is convex in prices on the other hand the recent literature on irreversible investment e g robert s pindyck 1988 giuseppe bertola 1988 has shown that increases in uncertainty lower investment all these results have been derived under either risk neutrality or complete markets intuition suggests that the explanation for such a difference lies with the asymmetric nature of adjustment costs in the irreversible investment case as compared with the symmetry of the adjustment cost mechanisms proposed by abel and hartman although this intuition is confirmed in this paper asymmetric adjustment costs are shown not to be sufficient to explain why the results differ in fact a more hidden but at least as important difference between these two literatures is that the former assumes perfect competition and constant returns to scale whereas the latter assumes either imperfect competition or decreasing returns to scale or both 2 the purpose of this paper is to highlight the role of the decreasing marginal return to capital assumption due to either imperfect competition or decreasing returns to scale or both in determining the effects of adjustment cost asymmetries on the sign of the response of investment to changes in uncertainty under risk neutrality for this the paper develops a simple model with a cost of adjustment mechanism general enough to consider both symmetric convexity and irreversibility as special cases one of the most important findings is the lack of robustness of the negative relationship between investment and uncertainty under asymmetric adjustment costs3 to changes in the degree of competition in fact when firms are nearly competitive the conclusion of hartman and of abel holds no matter how asymmetric adjustment costs are studying adjustment cost mechanisms has a central role in understanding the dynamics of investment and its business cycle implications but conclusive results about the sign of the instantaneous relationship between uncertainty and investment should not be department of economics columbia university new york ny 10027 i am grateful to giuseppe bertola prajit dutta glen hubbard anil kashyap richard lyons and the referees for their useful comments 1the financial literature on investment has considered risk aversion through a premium in the discount rate determined by the capm capital asset pricing model intertemporal capm or consumption capm however often this discount rate is left unchanged when studying the response of investment to uncertainty changes e g pindyck 1988 pp 974 5 thereby omitting the effect of changes in uncertainty on investment due to risk aversion and incomplete markets 2in the typical version of the irreversible investment problem there is no cost of upward adjustments thus imperfect competition and or decreasing returns to scale are required to bound the size of the firm 3in this paper asymmetric adjustment cost refers to the case in which it is more expensive to adjust downward than upward certainly the opposite case is a trivial extension of the case studied in this paper

the macroeconomic implications of rising wage inequality in the united states in recent decades american workers have faced a rising college premium a narrowing gender gap and increasing wage volatility this paper explores the quantitative and welfare implications of these changes the framework is an incomplete markets life cycle model in which individuals choose education intrafamily time allocation and savings given the observed history of the u s wage structure the model replicates key trends in cross sectional inequality in hours worked earnings and consumption recent cohorts enjoy welfare gains on average as higher relative wages for college graduates and for women translate into higher educational attainment and a more even division of labor within the household

competitive devaluations toward a welfare based approach abstract this paper revisits the international transmission of exchange rate shocks in a multicountry economy providing a choice theoretic framework for the policy analysis of competitive devaluations as opposed to the traditional view a devaluation by one country does not necessarily have an adverse beggar thy neighbor effect on its trading partners because they can benefit from an improvement in their terms of trade furthermore a retaliatory devaluation need not be the optimal strategy for the neighbor countries as the induced terms of trade deterioration can be large enough to offset the gains from defending their export market share the concern over competitive devaluations reflected in the fund s charter and the system wide implications of changes in exchange rates still motivate fund policy recommendations a major fund concern in the asian crisis has been the fear that asian currencies would become so undervalued and current account surpluses so large as to damage the economies of other countries developing countries included this is one reason the fund has stressed the need first to stabilize and then to strengthen exchange rates in the asian countries now in crisis and for this purpose not to cut interest rates until the currency stabilizes and begins to appreciate

resolving society s energy trilemma through the energy justice metric carbon dioxide emissions continue to increase to the detriment of society in many forms one of the difficulties faced is the imbalance between the competing aims of economics politics and the environment which form the trilemma of energy policy this article advances that this energy trilemma can be resolved through energy justice energy justice develops the debate on energy policy to one that highlights cosmopolitanism progresses thinking beyond economics and incorporates a new futuristic perspective to capture these dynamics of energy justice this research developed an energy justice metric ejm that involves the calculation of several metrics 1 a country national ejm 2 an ejm for different energy infrastructure and 3 an ejm which is incorporated into economic models that derive costs for energy infrastructure projects an ejm is modeled for china the european union and the united states and for different energy infrastructure in the united kingdom the ejm is plotted on a ternary phase diagram which is used in the sciences for analyzing the relationship trilemma of three forms of matter the development of an ejm can provide a tool for decision making on energy policy and one that solves the energy trilemma with a just and equitable approach

efficiency wages financial market integration and the fiscal multiplier abstract we used a new open economy macroeconomic model featuring a labor market friction in the form of efficiency wages to analyze the implications of financial market integration for the fiscal multiplier the fiscal multiplier measures the accumulated effect of fiscal policy on output conventional wisdom based on the basic textbook version of the classic mundell fleming model suggests that the fiscal multiplier should become smaller as financial markets become more integrated we show that a labor market friction in the form of efficiency wages implies that financial market integration should increase the fiscal multiplier

energy justice at the end of the wire enacting community energy and equity in wales energy justice has emerged as a useful lens for understanding and guiding energy decision making however whilst calls for greater energy justice have grown fleeting attention has been paid to the role and agency of the very people at the heart of this agenda clearly given the increasing prevalence of local energy initiatives such projects warrant more sustained focus both to explore how energy justice is constructed between settings and to prompt greater consideration of its associated outcomes this paper seeks to address this gap by using energy justice to assess local ownership of small scale energy generation through a study of the community energy sector in wales in so doing it aids greater understanding of the energy equity dimension understood in terms of accessibility and affordability of the energy trilemma from a conceptual standpoint the research examines how energy justice is negotiated and contested at community scale through a focus on issues of distributive and procedural justice from a policy standpoint the research shows that community energy is often involved in a wide range of local objectives and directs attention to how best to support such initiatives to further stimulate local action and deliver more widespread equity gains

competition imitation and growth with step by step innovation is more intense product market competition and imitation good or bad for growth this question is addressed in the context of an endogenous growth model with step by step innovations in which technological laggards must first catch up with the leading edge technology before battling for technological leadership in the future in contrast to earlier schumpeterian models in which innovations are always made by outsider firms who earn no rents if they fail to innovate and become monopolies if they do innovate here we find first that the usual schumpeterian effect of more intense product market competition pmc is almost always outweighed by the increased incentive for firms to innovate in order to escape competition so that pmc has a positive effect on growth second that a little imitation is almost always growth enhancing as it promotes more frequent neck and neck competition but too much imitation is unambiguously growth reducing the model thus points to complementary roles for competition anti trust policy and patent policy

the application of contrast explanation to energy policy research uk nuclear energy policy 2002 2012 abstract this paper advances the application of the methodology contrast explanation to energy policy research research in energy policy is complex and often involves inter disciplinary work which traditional economic methodologies fail to capture consequently the more encompassing methodology of contrast explanation is assessed and its use in other social science disciplines explored in brief it is then applied to an energy policy research topic in this case nuclear energy policy research in the uk contrast explanation facilitates research into policy and decision making processes in energy studies and offers an alternative to the traditional economic methods used in energy research further contrast explanation is extended by the addition of contested and uncontested hypotheses analyses this research focuses on the methods employed to deliver the new nuclear programme of the uk government in order to achieve a sustainable nuclear energy policy three issues are of major importance 1 law policy and development 2 public administration and 3 project management further the research identifies that policy in the area remains to be resolved in particular at an institutional and legal level however contrary to the literature in some areas the research identifies a change of course as the uk concentrates on delivering a long term policy for the nuclear energy sector and the overall energy sector

politicizing energy justice and energy system transitions fossil fuel divestment and a just transition the burgeoning energy justice scholarship highlights the importance of justice and equity concerns in the context of global decarbonization and the transition to a green economy this paper seeks to extend current conceptualizations of energy justice across entire energy lifecycles from extraction to final use to offer an analytically richer and more accurate picture of the in justice impacts of energy policy decisions we identify two key areas that require greater attention and scrutiny in order to enact energy justice within a more democratized energy system first we call for greater recognition of the politics power dynamics and political economy of socio technical energy transitions we use the example of the fossil fuel divestment movement as a way to shift energy justice policy attention upstream to focus on the under researched injustices relating to supply side climate policy analysis and decisions second the idea of a just transition and the distributional impacts on and the role of labor in low carbon transitions must be addressed more systematically this focus produces a more directly political and politicizing framing of energy in justice and a just energy transition

international dimensions of optimal monetary policy abstract this paper provides a baseline general equilibrium model of optimal monetary policy among interdependent economies with monopolistic firms and nominal rigidities an inward looking policy of domestic price stabilization is not optimal when firms markups are exposed to currency fluctuations such a policy raises exchange rate volatility leading foreign exporters to charge higher prices vis a vis increased uncertainty in the export market as higher import prices reduce the purchasing power of domestic consumers optimal monetary rules trade off a larger domestic output gap against lower consumer prices optimal rules in a world nash equilibrium lead to less exchange rate volatility relative to both inward looking rules and discretionary policies even when the latter do not suffer from any inflationary or deflationary bias gains from international monetary cooperation are related in a non monotonic way to the degree of exchange rate pass through

excess capacity monopolistic competition and international transmission of monetary disturbances analyzes the excess capacity monopolistic competition and international transmission of monetary policy disturbances in the united states sheds light on the international impact of monetary policy emphasis on the spillover effects of monetary disturbances similarity of framework used with open economy macroeconomics

assessing fairness of dynamic grid tariffs the increase in the supply of intermittent renewable energy and the higher electricity use lead to stronger variation in network usage which either requires costly network extensions or the implementation of incentives to reduce peaks this paper focuses on the latter namely dynamic tariffs however a tension may exist between economic arguments for dynamic pricing and people perceiving such pricing as unfair this paper seeks to assess the fairness of dynamic tariffs through a combination of theoretical and empirical research fairness is defined broader than inequality it is understood more objectively than just people s perceptions and thus requires engagement with ethical theory and the fairness analysis is not only based on abstract ethical reflection but also on analysing the underlying arguments for people s perceptions both the theoretical fairness assessment and the survey among dutch households reveal that dynamic tariffs are less fair than transport and capacity tariffs and fairer than ramsey pricing the fairness of dynamic tariffs depends on implementation conditions such as clear non economic arguments as justification guarantying basic needs fulfilment decreasing perception that peak use is only for the rich and increasing predictability
