multinationals productivity advantage scale or technology this study decomposes the productivity advantage of foreign multinationals into a technology and a scale effect and analyses the causal relationship between foreign ownership and these two components this is done by analyzing the effects of an acquisition of a domestic establishment by a foreign multinational using a combined propensity score matching and difference in differences estimation the main results show that any positive impact of acquisition is predominantly due to changes in technical efficiency and not in scale and that the preacquisition productivity of the target plays a role in mediating the rate of technology transfer from the multinational jel f23 l22

reforms of environmental policies in the presence of cross border pollution and public private clean up we construct a two country model where pollution from production is transmitted across borders pollution abatement is undertaken by both private producers and the public sector we characterize nash optimal levels of the policy instruments in the two countries emission taxes and funds allocated for public abatement activities we examine the implications of a number of multilateral policy reforms one of our findings is that the magnitude of the beneficial effect of a reform depends on the scope of the reform if it is restricted to a subset of policy instruments then the efficacy of environmental policy reform can be greatly undermined

can cross border pollution reduce pollution we develop a two country model of foreign aid and cross border pollution result ing from production activities in the recipient country there is both private and public abatement of pollution the latter being financed through emissions tax revenue and foreign aid we characterize a nash equilibrium in which the donor country chooses the amount of aid and the recipient chooses the fraction of aid allocated to pollution abatement and the emission tax rate at this equilibrium an increase in the donor s perceived rate of cross

the short and long run effects of tied foreign aid on pollution abatement pollution and employment a pilot model abstract there exists in the literature a presumption that tied foreign aid can be used effectively to reduce cross border pollution focusing in contrast to the received literature on the interaction between the public and private provisions of pollution abatement in the recipient country we question the effectiveness of tied foreign aid in reducing pollution in this context we obtain many novel and policy relevant insights allowing for changes in labour employment and distinguishing between short and long run effects tied foreign aid is shown to crowd out the private provision for pollution abatement in the short run in the long run tied foreign aid raises employment and therefore may be desirable for the recipient but undesirable for the donor country because it also raises pollution the results change drastically if only the government provides pollution abatement

fdi as an outcome of the market for corporate control theory and evidence abstract much foreign direct investment fdi takes the form of mergers and acquisitions m a it is commonplace in finance to view acquisitions as manifestations of the market for corporate control following on that insight we propose a model of fdi in which headquarters bid to control overseas assets we derive an equation for bilateral fdi stocks that resembles the recently developed fixed effects approach to modelling bilateral trade flows we estimate the model and use its parameters to construct benchmarks for evaluating multilateral inward and outward fdi

demand side bidding agents modeling and simulation problems such as price volatility have been observed in electric power markets demand side participation is frequently offered as a potential solution by promising to increase market efficiency when hockey stick type offer curves are present however the individual end consumer will surely value electricity differently which makes demand side participation difficult as a group and at a bus in this paper demand is categorized into two groups one that highly values reliability and one that does not the two types are modeled separately and a new optimal bidding function is developed and tested based on this model

exploring the effect of producer services agglomeration on china s energy efficiency under environmental constraints abstract this paper makes an empirical analysis of the effect of producer services agglomeration on china s energy efficiency under environmental constraints eee by using spatial durbin model the results show that at the national level the urbanization agglomeration of producer services not only improves the local eee significantly but also has an obvious spatial spillover effect on the surrounding regions while the localization agglomeration of producer services is only beneficial to the improvement of the local eee from the regional perspective both the urbanization and localization agglomeration of producer services show significant promotion effect and spatial spillover effect on china s eee in the east region and the promotion effect of the urbanization agglomeration of producer services is greater while the improvement of eee in the central and west regions mainly depend on the mar externality of producer services agglomeration and its spatial spillover effects are not obvious moreover the above empirical results exhibit strong robustness based on these empirical findings this paper puts forward some specific suggestions for improving china s eee so as to achieve the multi win of economic growth energy conservation and environmental protection the study contributes to improving the environmental quality and speeding up the construction of beautiful china

market clearing with stochastic security part i formulation the first of this two paper series formulates a stochastic security constrained multi period electricity market clearing problem with unit commitment the stochastic security criterion accounts for a pre selected set of random generator and line outages with known historical failure rates and involuntary load shedding as optimization variables unlike the classical deterministic reserve constrained unit commitment here the reserve services are determined by economically penalizing the operation of the market by the expected load not served the proposed formulation is a stochastic programming problem that optimizes concurrently with the pre contingency social welfare the expected operating costs associated with the deployment of the reserves following the contingencies this stochastic programming formulation is solved in the second companion paper using mixed integer linear programming methods two cases are presented a small transmission constrained three bus network scheduled over a horizon of four hours and the ieee reliability test system scheduled over 24 h the impact on the resulting generation and reserve schedules of transmission constraints and generation ramp limits of demand side reserve of the value of load not served and of the constitution of the pre selected set of contingencies are assessed

stochastic modelling of renewable energy sources from operators point of view a survey abstract high penetration of renewable energy sources especially weather dependent sources has increased the power systems uncertainties for any analysis in power systems such as planning and operation it is essential to confront the stochastic nature of these sources in order to get much more precise results since operators need proper strategies and methods to decline negative effects of the stochastic behaviour of renewable power generators such as total operation cost growth this paper provides a review of different state of the art approaches from the operator s viewpoint for handling the stochastic behaviour of renewable sources hence in this paper three different strategies are categorized for stochastic analysis of these sources the first strategy is mathematical modelling including stochastic dependency and independency multi dimensional dependence forecast and scenarios afterwards demand side management which is one of the other approaches for dealing with these uncertainties is investigated and different demand response programs and some methods to model them are presented finally the effect of different electricity market schemes and relevant optimization methods to mitigate the variations of renewable energy sources are discussed the study demonstrates that an operator should choose one or a combination of these three approaches based on its requirements

flexible demand and supply as enablers of variable energy integration abstract this article analyses the impact of the interplay between the demand response wind penetration and hydropower in the nordic power market long term equilibrium model is developed in which the thermal power capacity adjusts to the zero profit level over varying real time pricing adoption rates and wind power shares the results show that an increased demand response decreases the amount of thermal power capacity and improves the utilization rate of thermal power and the value of wind power there is a decreasing marginal gain from an increasing demand response adoption with respect to the thermal utilization and wind value factor however the demand response itself does not lead to lower co2 emissions or reduced variation in hydropower generation

controlling electricity consumption by forecasting its response to varying prices in a real time electricity pricing context where consumers are sensitive to varying prices having the ability to anticipate their response to a price change is valuable this paper proposes models for the dynamics of such price response and shows how these dynamics can be used to control electricity consumption using a one way price signal estimation of the price response is based on data measurable at grid level removing the need to install sensors and communication devices between each individual consumer and the price generating entity an application for price responsive heating systems is studied based on real data before conducting a control by price experiment using a mixture of real and synthetic data with the control objective of following a constant consumption reference peak heating consumption is reduced by nearly 5 and 11 of the mean daily heating consumption is shifted

intra industry foreign direct investment we use a new firm level data set that establishes the location ownership and activity of 650 000 multinational subsidiaries close to a comprehensive picture of global multinational activity a number of patterns emerge from the data most foreign direct investment fdi occurs between rich countries the share of vertical fdi subsidiaries which provide inputs to their parent firms is larger than commonly thought even within developed countries more than half of all vertical subsidiaries are only observable at the four digit level because the inputs they are supplying are so proximate to their parent firms final good that they appear identical at the two digit level we call these proximate subsidiaries intra industry vertical fdi and find that their location and activity are significantly different to the inter industry vertical fdi visible at the two digit level these subsidiaries are not readily explained by the comparative advantage considerations in traditional models where firms locate their low skill production stages abroad in low skill countries to take advantage of factor cost differences we find that overwhelmingly multinationals tend to own the stages of production proximate to their final production giving rise to a class of high skill intra industry vertical fdi

bottom up world climate policies preserving fossil fuel deposits vs capping fuel consumption the policy of purchasing fossil fuel deposits for preservation is an alternative to the demand side climate policies that predominate in practice and in professional studies this paper analyzes the deposit purchase approach and compares it to the standard demand side policy in a model with international trade and non cooperative governments that account for the effects of their policies on equilibrium prices we investigate how the two regimes differ with respect to their equilibrium allocations and in particular with respect to the countries mitigation effort and welfare if countries are symmetric mitigation is stronger in the demand side than in the supply side regime and the transition from the latter to the former is welfare enhancing for all countries if countries have different endowments of deposits in a two country economy the country with higher extraction costs does not purchase deposits for preservation and the country with lower extraction costs is better off with the supply side than with the demand side policy finally we consider the case of combined policies and find surprisingly that no equilibrium in pure strategies exists when heterogeneous countries apply both policy instruments politiques climatiques mondiales ascendantes preservation des gisements de combustibles fossiles par opposition a la limitation de la consommation de carburant la politique d achat de gisements de combustibles fossiles aux fins de preservation represente une alternative aux politiques climatiques axees sur la demande predominant a la fois dans la pratique mais aussi dans les etudes professionnelles cet article analyse l approche fondee sur l achat de gisements et la compare a la politique standard axee sur la demande dans un modele de commerce international et de gouvernements non cooperatifs prenant en compte les effets de leurs politiques sur les prix d equilibre nous avons recherche en quoi les deux regimes differaient relativement a leur repartition de l equilibre et notamment relativement a l effort d attenuation et a la protection sociale si les pays sont symetriques l attenuation est plus prononcee dans un systeme axe sur la demande comparativement a un systeme axe sur l offre et la transition du second au premier systeme permet d ameliorer la protection sociale pour tous les pays dans une economie a deux pays differemment dotes en matiere de gisements le pays ayant les couts d extraction les plus eleves n achete pas de gisements a des fins de preservation tandis que le pays ayant les couts d extraction les moins eleves se retrouve en meilleure posture dans une politique axee sur l offre plutot que sur la demande pour terminer nous examinons le cas des politiques combinees et etonnamment nous constatons qu il n existe aucun equilibre en matiere de strategies pures lorsque des pays heterogenes appliquent les deux moyens d action

club membership and transboundary pollution evidence from the european union enlargement we set up a theoretical model in which a less developed country the ldc undertakes an activity that imposes negative transboundary pollution effects on a more developed country the mdc the mdc can effectively make a coasian payment in the form of direct environmental assistance but can also encourage good environmental citizenship through its influence over the prospect that the ldc will gain the benefits of membership into a particular international club we examine the strategic interactions between the ldc and the mdc in this regional environmental game and our comparative statics analysis explores how a change in the membership payoff will affect the environmental efforts and outcome of both countries our theoretical model also addresses the issue of the economic growth in the ldc as well as its environmental impacts in the region we also conduct empirical study and examine the evidence in the thirteen central and eastern european cee countries that joined the european union eu in the 21st century and investigate the impacts of eu membership on their environmental performance we find that there is a robust correlation between the degree of eu integration and pollution abatement from the ldc and we also observe that emissions of selected pollutants seem to follow a concave pattern relative to the national income both of which coincide with our theoretical discussions

a survey of load control programs for price and system stability load control and demand side load management programs have been implemented in a large number of competitive power markets these programs can provide enhanced system security and many benefits to participants this paper reviews and compares existing economically driven programs

foreign direct investment heterogeneous workers and employment security evidence from germany we analyze how foreign direct investment fdi affects employment security using administrative microdata for german employees measuring fdi intensity at the industry level enables us to take into account the sum of direct effects at multinationals as well as indirect effects of fdi throughout the affected industry we find that both inward and outward fdi significantly reduce employment security this is particularly the case for inward fdi coming from the western part of the european union as well as for outward fdi going to central and eastern europe the effects are sizeable for older and low skilled workers

optimal generation mix with short term demand response and wind penetration demand response defined as the ability of load to respond to short term variations in electricity prices plays an increasingly important role in balancing short term supply and demand especially during peak periods and in dealing with fluctuations in renewable energy supplies however demand response has not been included in standard models for defining the optimal generation technology mix three different methodologies are proposed to integrate short term responsiveness into a generation technology mix optimization model considering operational constraints elasticities are included to adjust the demand profile in response to price changes including cross price elasticities that account for load shifts among hours as energy efficiency programs also influence the load profile interactions of efficiency investments and demand response are also modeled comparison of model results for a single year optimization with and without demand response shows peak reduction and valley filling effects impacting the optimal amounts and mix of generation capacity increasing demand elasticity also increases the installed amount of wind capacity suggesting that demand response yields environmental benefits by facilitating integration of renewable energy

international trade and the environment policy reform in a polluted small open economy abstract this paper investigates sufficient conditions for welfare improving policy reforms in a small open economy facing many trade and pollution distortions we investigate and compare reform in tax regimes quota regimes and mixed regimes where some pollutants are regulated with taxes and others with quotas it is also shown that the welfare benefits of reforming pollution policy are greater in an economy with international factor mobility than in an economy not subject to such mobility

benefits and challenges of electrical demand response a critical review advances in it control and forecasting capabilities have made demand response a viable and potentially attractive option to increase power system flexibility this paper presents a critical review of the literature in the field of demand response providing an overview of the benefits and challenges of demand response these benefits include the ability to balance fluctuations in renewable generation and consequently facilitate higher penetrations of renewable resources on the power system an increase in economic efficiency through the implementation of real time pricing and a reduction in generation capacity requirements nevertheless demand response is not without its challenges the key challenges for demand response centre around establishing reliable control strategies and market frameworks so that the demand response resource can be used optimally one of the greatest challenges for demand response is the lack of experience and the consequent need to employ extensive assumptions when modelling and evaluating this resource this paper concludes with an examination of these assumptions which range from assuming a fixed linear price demand relationship for price responsive demand to modelling the highly diverse distributed and uncertain demand response resource as a single centralised negative generator adopting fixed characteristics and constraints

business models as drivers of the low carbon power system transition a multi level perspective abstract decarbonising the electrical power system holds a critical role in climate change mitigation recent developments in technology are helping change the current centralized paradigm into one of integrated distributed clean energy resources in spite of these developments radical transformation is not occurring at a speed to effectively meet environmental targets mostly due to the incumbent carbon lock in trajectory we argue that business model bm innovation dynamics are key drivers in accelerating the low carbon power system transition often operating irrespective of the underlying technology we combine bm theory with the multi level perspective on sociotechnical transitions to present a useful framework to analyze this potential transition this paper presents the application of this framework characterizing relevant bm dynamics of niche and regime business actors and supporting these with illustrative examples particularly we find that new actors in the distributed energy business are achieving market scale by offering financially innovative bms that do not require upfront costs from customers higher penetrations of renewable energy sources in liberalized electricity markets are destabilizing the historical bm of large centralized utilities through erosion of wholesale prices furthermore a shift towards distributed and dynamic energy resources further challenges incumbents and might bring opportunities for bms focused on active customer participation and social value creation as these tendencies are expected to accelerate we find analyses of bms will have important relevance for future power system transition research

aggregate industrial energy consumer response to wholesale prices in the restructured texas electricity market abstract the aggregate response of consumers to wholesale price signals is very limited in the restructured electric reliability council of texas ercot market an overall average own price elasticity of demand of 0 000008 for industrial energy consumers served at transmission voltage is estimated using a symmetric generalized mcfadden cost function model to date ercot has sought to promote demand response to price signals without reliance on stand alone demand response programs but with a market structure that is designed to facilitate economic demand response this very limited responsiveness to wholesale price signals may prove problematic in light of policy decisions to pursue an energy only resource adequacy mechanism for ercot

how serious is the aggregation problem an empirical illustration heterogeneity in consumer behaviour may create problems with aggregation across consumers if so we may not be able to make correct inferences about behaviour based on aggregated data however using micro estimates to predict aggregate demand responses to policy changes may also create a bias if not aggregated properly this may sound like a catch 22 situation but it is not as it is possible to calculate both micro and aggregate demand responses based on microdata the size of the aggregation bias is an empirical question in this article we show how to calculate theoretically consistent aggregate demand responses we use both micro and macro data for norwegian household electricity consumption to illustrate the magnitude and direction of different aggregation biases we find considerable aggregation biases in particular when estimating with macro data

jevons paradox revisited the evidence for backfire from improved energy efficiency beginning with william stanley jevons in 1865 a number of authors have claimed that economically justified energy efficiency improvements will increase rather than reduce energy consumption jevons paradox is extremely difficult to test empirically but could have profound implications for energy and climate policy this paper summarises and critiques the arguments and evidence that have been cited in support of jevons paradox focusing in particular on the work of len brookes and harry saunders it identifies some empirical and theoretical weaknesses in these arguments highlights the questions they raise for economic orthodoxy and points to some interesting parallels between these arguments and those used by the biophysical school of ecological economics while the evidence in favour of jevons paradox is far from conclusive it does suggest that economy wide rebound effects are larger than is conventionally assumed and that energy plays a more important role in driving productivity improvements and economic growth than is conventionally assumed

income and price elasticities of electricity demand aggregate and sector wise analyses abstract cointegration and vector error correction modeling approaches are widely used in electricity demand analysis the study rigorously examines the determinants of electricity demand at aggregate and sectoral levels in pakistan in the backdrop of severe electricity shortages our empirical findings give support to the existence of a stable long run relationship among the variables and indicate that electricity demand is elastic in the long run to both income and price at aggregate level at sectoral level long run income and price elasticity estimates follow this pattern except in agricultural sector where electricity demand is found elastic to output but inelastic to electricity price on the contrary the coefficients for income and price are rather small and mostly insignificant in the short run we employed temperature index price of diesel oil and capital stock at aggregate and sectoral levels as exogenous variables these variables account for most of the variations in electricity demand in the short run it shows that mechanization of the economy significantly affect the electricity demand at macro level moreover elastic electricity demand with respect to electricity price in most of the sectors implies that electricity price as a policy tool can be used for efficient use and conservation

an economic welfare analysis of demand response in the pjm electricity market abstract we analyze the economic properties of the economic demand response dr program in the pjm electricity market in the united states using dr market data pjm s program provided subsidies to customers who reduced load in response to price signals the program incorporated a trigger point at a locational marginal price of 75 mwh at or beyond which payments for load reduction included a subsidy payment particularly during peak hours such a program saves money for the system but the subsidies involved introduce distortions into the market we simulate demand side bidding into the pjm market and compare the social welfare gains with the subsidies paid to price responsive load using load and price data for year 2006 the largest economic effect is wealth transfers from generators to non price responsive loads based on the incentive payment structure that was in effect through the end of 2007 we estimate that the social welfare gains exceed the distortions introduced by the subsidies lowering the trigger point increases the transfer from generators to consumers but may result in the subsidy outweighing the social welfare gains due to load curtailment we estimate that the socially optimal range for the incentive trigger point would be 66 77 mwh

a meta analysis on the price elasticity of energy demand abstract price elasticities of energy demand have become increasingly relevant in estimating the socio economic and environmental effects of energy policies or other events that influence the price of energy goods since the 1970s a large number of academic papers have provided both short and long term price elasticity estimates for different countries using several models data and estimation techniques yet the literature offers a rather wide range of estimates for the price elasticities of demand for energy this paper quantitatively summarizes the recent but sizeable empirical evidence to facilitate a sounder economic assessment of in some cases policy related energy price changes it uses meta analysis to identify the main factors affecting short and long term elasticity results for energy in general as well as for specific products i e electricity natural gas gasoline diesel and heating oil

public pollution abatement regional capital mobility and tax competition the environmental economics literature has ignored the effects of the interaction among capital mobility private and public pollution abatement and cross border pollution on environmental policies we analyze these effects in the context of a general equilibrium model we find among other things that i when countries are symmetric the presence of public pollution abatement makes nash equilibrium pollution taxes efficient while lump sum taxes remain inefficient and ii when countries are asymmetric both taxes are inefficient and the nash equilibrium pollution taxes depend mainly on the direction of capital mobility factor intensity and the degree of cross border pollution these results indicate that policy cooperation is more important when countries are different

measurement of energy rebound effect in households evidence from residential electricity consumption in beijing china abstract energy efficiency improvement policies have special significance for carbon emissions reduction and the mitigation of the effects of climate change however the energy rebound effect caused by technological progress will indirectly increase energy consumption the magnitude of the rebound effect largely determines the effectiveness of energy efficiency in mitigating energy consumption this study reviews the main theory behind estimated methods of energy rebound effect measurement focuses on constructing a double logarithm energy demand model and an error correction model of the asymmetric demand responses of electricity price changes to empirically analyse the direct rebound effect on residential electricity use in beijing it integrates consumer s demand theory with the embodied electricity of household spending from a seven sector environmental energy input output e i o analysis to estimate the indirect rebound effect the three income elasticity weight change and proportional re spending scenario simulation results show that residential electricity use in beijing exhibits a partial rebound effect and the long term direct and indirect rebound effects are 46 to 56 and the short term direct rebound effect is 24 to 37 finally the direct and indirect energy rebound effect for various income groups needs further research an appropriate policy mix should be adopted to mitigate effectively the rebound effect in china s current lower energy price and lower energy efficiency market

the effect of foreign acquisition on employment and wages evidence from finnish establishments employee characteristics by skill groups makes it possible to disentangle the effect of foreign ownership on wages from its effects on the quality of the workforce furthermore this information allows us to examine the heterogeneity of the effect of foreign acquisition on wages and employment third the long timespan of our data thirteen years enables us to consider the effects of foreign acquisition in the long run hiring and firing costs may delay the effects of foreign acquisition by looking at the effects of acquisition in several periods after it has taken place these delays can be taken into account we believe finland to be an interesting case study for the effects of foreign ownership it is a typical example of a small open economy where foreign investment plays an important role furthermore our data cover the years 1988 2001 when the share of foreign direct investments rose rapidly in finland this increase is depicted in figure 1 and it partly reflects the worldwide trend in foreign direct investment but the years 1988 2001 were also characterized by two phenomena which undoubtedly led to the increase in the share of foreign owned firms first finland experienced a very severe recession in the early 1990s and the recovery from this crisis was associated with a rapid restructuring of the economy and a growth of new industries in particular the export oriented high tech sector 2 second finland joined the european union in 1995 which naturally removed a considerable number of barriers to foreign investment in the finnish economy the results derived by both matching and regression methods indicate that foreign acquisition has a positive effect on wages in all skill groups this wage increase is not immediate but occurs within one to three years after the acquisition the magnitude of this effect increases with the level of schooling of the workers the results indicate that there is a small decrease in the share of highly educated workers after foreign acquisition the decrease in the share of highly educated workers after acquisition also seems to hold for domestic acquisitions the paper is organized as follows the next section briefly describes the theoretical background for the analysis and reviews some previous empirical findings the third section describes the statistical framework and the fourth section presents the data sets the results are provided in the fifth section the last section concludes the paper

carbon capture and storage and transboundary pollution a differential game approach abstract we study the strategic behavior of two countries facing transboundary co2 pollution under a differential game setting in our model the reduction of co2 concentration occurs through the carbon capture and storage process rather than through the adoption of cleaner technologies furthermore we first provide the explicit short run dynamics for this dynamic game with symmetric open loop and a special markovian nash strategy then we compare these strategies at the games steady states and along some balanced growth paths our results show that if the initial level of co2 is relatively high state dependent emissions reductions can lead to higher overall environmental quality hence feedback strategy leads to less social waste

carbon emission intensity in electricity production a global analysis we study changes in the aggregate carbon intensity aci for electricity at the global and country levels the aci is defined as the energy related co2 emissions in electricity production divided by the electricity produced it is a performance indicator since a decrease in its value is a desirable outcome from the environmental and climate change viewpoints from 1990 to 2013 the aci computed at the global level decreased only marginally however fairly substantial decreases were observed in many countries this apparent anomaly arises from a geographical shift in global electricity production with countries having a high aci increasingly taking up a larger electricity production share it is found that globally and in most major electricity producing countries reduction in their aci was due mainly to improvements in the thermal efficiency of electricity generation rather than to fuel switching estimates of the above mentioned effects are made using lmdi decomposition analysis our study reveals several challenges in reducing global co2 emissions from the electricity production sector although technically the reduction potential for the sector is known to be great

the impact of selected abatement strategies on transnational pollution the terms of trade and factor rewards a general equilibrium approach abstract widespread publicity of international conflict over transfrontier pollutants such as acid deposition and the november 1986 chemical spill in the rhine river has increased the public s awareness of the need to devise abatement strategies appropriate for transnational pollution this article develops a general equilibrium approach for analyzing the economic impacts of selected abatement strategies the model includes internationally mobile goods capital and pollution flows and flexible output and factor prices the general equilibrium approach provides policymakers with important information which is usually not revealed by a partial equilibrium approach that is demonstrated by applying the model to the north american acid deposition issue

household responsiveness to residential demand response strategies results and policy implications from a swedish field study abstract to realize the benefits of smart grids residential demand response dr aims to increase demand flexibility by influence household electricity consumption although price based dr programs have shown potential there is a need to further investigate the effectiveness of dr in energy strategy and policy development the evaluation of dr has focused on the impact on overall power demand assuming that consumers are economically rational decision maker however recent findings suggest that consumer responses have been insufficient and calls have been made to identify novel evaluation approaches that better reflect the human dimension of energy consumption continuing this line of enquiry this paper aims to investigate the effectiveness of dr and explore the potential of environmental incentives for increased consumer engagement we propose an interdisciplinary evaluation framework to understand variations in household responsiveness to dr strategies which is tested in a swedish dr field trial covering 136 households during 2017 results suggest that the effectiveness of dr varies widely across household type ranging from substantial reductions in overall consumption and during peak periods to increases in consumption during peak periods furthermore a clear favor of price incentives compared to environmental incentives as the most efficient strategy to increase demand flexibility was observed

on the efficient market diffusion of intermittent renewable energies abstract capacity costs of renewable energies have been decreasing dramatically and are expected to fall further making them more competitive with fossils building on an analytically tractable peak load pricing model we analyze how intermittency of renewable energies affects the market diffusion that results from these lower costs in particular once renewables have become competitive by attaining the same levelized cost of electricity lcoe as fossils the marginal increase in efficient capacities due to a further cost reduction varies substantially initially it is small then it rises but it falls again once renewable capacities are large enough to satisfy the whole electricity demand at times of high availability if external costs of fossils are internalized by a pigouvian tax then perfect competition leads to efficient investments in renewable and fossil capacities even though we assume that only a subgroup of consumers can adapt their demand to price fluctuations that are caused by the intermittency of renewables moreover fossils receive a capacity payment through the market for their reliability in serving demand of non reactive consumers maximum electricity prices rise with the share of renewables if regulators impose a price cap this initially raises investments in renewables but the effect may reverse if the share of renewables is large

volatility of power grids under real time pricing the paper proposes a framework for modeling and analysis of the dynamics of supply demand and clearing prices in power systems with real time retail pricing and information asymmetry characterized by passing on the real time wholesale electricity prices to the end consumers real time pricing creates a closed loop feedback system between the physical layer and the market layer of the system in the absence of a carefully designed control law such direct feedback can increase sensitivity and lower the system s robustness to uncertainty in demand and generation it is shown that price volatility can be characterized in terms of the system s maximal relative price elasticity defined as the maximal ratio of the generalized price elasticity of consumers to that of the producers as this ratio increases the system may become more volatile since new demand response technologies increase the price elasticity of demand and since increased penetration of distributed generation can also increase the uncertainty in price based demand response the theoretical findings suggest that the architecture under examination can potentially lead to increased volatility this study highlights the need for assessing architecture systematically and in advance in order to optimally strike the trade offs between volatility robustness and performance metrics such as economic efficiency and environmental efficiency

review of key international demand elasticities for major industrializing economies abstract this paper conducts a selective review of various estimates for energy demand responses focused specially upon lower income industrializing economies rather than richer mature nations it emphasizes recent trends from empirical studies that have been published after 2000 emphasis is placed on the five major emerging or transitional economies in brazil china india mexico and russia although other important nations like chile and south korea are also discussed when studies are available the review focuses attention on the long run responses to changes in prices and income after capital stock turnover has been completed the terminology often refers to elasticities or the percentage change in energy use divided by the percentage change in price or income holding constant all other factors that could influence energy use decisions estimates cover petroleum products natural gas and electricity although the available studies often ignore coal they also include the economy wide impacts real gdp to price changes most studies have focused upon household and transportation use of liquid fuels many fewer studies have investigated fuels used by industry or commerce or for electric generation based upon the available estimates price and income elasticities for liquid fuels are generally less than one unity for many countries and sectors except for the long run income effect for transportation purposes which can range widely by country between 0 24 and 1 75 while averaging 0 94 for all countries

power markets in transition decarbonization energy efficiency and short term demand response abstract energy efficiency and short term demand response are key issues in the decarbonization of power markets however their interaction and combined impact on market prices as well as on the supply side is yet to be understood we develop a framework to implement short term demand response and investments in energy efficiency in detailed partial equilibrium power market models we quantify our results using the eu regen model for the european power market under an 80 emission reduction target energy efficiency contributes only 11 of carbon emission reductions intermittent renewable energies such as wind and solar power account for the major share of 53 in comparison to a scenario without short term demand response and energy efficiency investments 70 gw gas power is decommissioned immediately and 180 gw less gas capacity is needed in 2050 which underlines the need for immediate action by policy makers to avoid locking the eu power market into an inefficient path

new firm survival new results using a hazard function a limitation of audretsch s 1991 study of new firm survival was the level of aggregation to industries this precluded linking establishment specific characteristics such as organizational structure and size to post entry performance the purpose of this paper is to relate the post entry performance of individual establishments not only to their technological and market structure environments but also to establishment specific characteristics we do this by estimating a hazard duration function for more than 12 000 individual establishments in u s manufacturing started in 1976 by tracking their subsequent performance over a ten year period we conclude that establishment specific characteristics which audretsch was not able to capture in his earlier study play an important role in shaping the exposure to risk confronting new establishments copyright 1995 by mit press

cross border externalities and trade liberalization the strategic control of pollution the authors examine international trade in a commodity whose production creates a negative externality for the importing country and they consider the nations strategic policy choices when they can restrict trade and when they are bound by a free trade agreement when pollution abatement technology is available the exporting country induces its adoption despite national indifference to the externality in order to reduce the tariff in a free trade agreement environmental policy is used to exploit monopoly power in trade an alternative policy instrument a process standard is introduced national competition in controlling emissions leads to very restrictive antipollution measures we examine international trade in a commodity whose production creates a negative externality for the importing country and we consider the nations strategic policy choices when they can restrict trade and when they are bound by a free trade agreement when pollution abatement technology is available the exporting country induces its adoption despite national indifference to the externality in order to reduce the tariff in a free trade agreement environmental policy is used to exploit monopoly power in trade an alternative policy instrument a process standard is introduced national competition in controlling emissions leads to very restrictive anti pollution measures

review and comparison of demand response options for more effective use of renewable energy at consumer level abstract power grids have faced major challenges such as increasing consumption peak demand and co 2 emission distributed generation dg as a solution to these issues is affected by source intermittency grid side limited storage capabilities and supply demand mismatch in order to achieve more benefits and profits for both customers and the utility integrated demand management techniques can be used this paper reviews the issues caused by high penetration of renewables in power production depending on utility characteristics in addition several methods in the literature were reviewed and their both single and combined use was investigated with a comparison study in turkey in field data based simulations consumption of refrigerators were scheduled according to the output of a small scale pv system and changes in consumption in a year were calculated the results were analyzed and compared with each other from the standpoint of change in amount of power taken from grid number of active operation hours shifted to solar periods change in annual consumption and achievable savings in electricity bills in addition to the analysis and comparison of several management methods the paper also proposes a number of terms that widens applicability and can be used in decision making processes

structural models and endogeneity in corporate finance the link between managerial ownership and corporate performance this paper presents a parsimonious structural model that isolates primary economic determinants of the level and dispersion of managerial ownership firm scale and performance and the empirical associations among them in particular variation across firms and through time of estimated productivity parameters for physical assets and managerial input and corresponding variation in optimal compensation contract and firm size combine to deliver the well known hump shaped relation between tobin s q and managerial ownership to assess the effectiveness of standard econometric approaches to the endogeneity problem we apply those remedies to panel data generated from the model the unfortunate conclusion is that at least in the ownership performance context proxy variables fixed effects and instrumental variables do not generally provide reliable solutions to simultaneity bias

foreign acquisition plant survival and employment growth this paper analyses the effect of foreign acquisition on survival probability and employment growth of target plant using data on swedish manufacturing plants during the period 1993 2002 an improvement over previous studies is that we take into account firm level heterogeneity by separating the targeted plants into those within swedish mnes swedish exporting non mnes and purely domestic firms before foreign takeover the results controlling for possible endogeneity of the acquisition dummy using an iv and propensity score matching approach suggest that acquisition by foreign owners increases the lifetime of the acquired plants only if the plant was an exporter the effect differs depending on whether the acquisition is horizontal or vertical we also find robust positive employment growth effects only for exporters and only if the takeover is vertical not horizontal

optimal taxes on fossil fuel in general equilibrium we analyze a dynamic stochastic general equilibrium dsge model with an externality through climate change from using fossil energy our central result is a simple formula for the marginal externality damage of emissions or equivalently for the optimal carbon tax this formula which holds under quite plausible assumptions reveals that the damage is proportional to current gdp with the proportion depending only on three factors i discounting ii the expected damage elasticity how many percent of the output flow is lost from an extra unit of carbon in the atmosphere and iii the structure of carbon depreciation in the atmosphere thus the stochastic values of future output consumption and the atmospheric co2 concentration as well as the paths of technology whether endogenous or exogenous and population and so on all disappear from the formula we find that the optimal tax should be a bit higher than the median or most well known estimates in the literature we also formulate a parsimonious yet comprehensive and easily solved model allowing us to compute the optimal and market paths for the use of different sources of energy and the corresponding climate change we find coal rather than oil to be the main threat to economic welfare largely due to its abundance we also find that the costs of inaction are particularly sensitive to the assumptions regarding the substitutability of different energy sources and technological progress

political uncertainty and the earmarking of environmental taxes abstract far from being used to secure a double dividend by reducing distorting taxes revenues from environmental taxes seem quite often to be earmarked to particular spending programs in the us for example a range of such taxes feed into environmental trust funds such earmarking runs counter to standard notions of good practice in taxing and spending this paper develops and explores an explanation of such apparent inefficiencies in terms of political uncertainty roughly a green incumbent may chose to earmark revenues if the efficiency loss from doing so is outweighed by the value of constraining subsequent and potentially non green policy makers from wasting the funds raised it emerges for example that those most likely to earmark are green politicians who are politically weak and that earmarking then enables such a policy maker to set the corrective tax higher than they otherwise would but nevertheless lower than the pigovian tax

do energy efficiency investments deliver evidence from the weatherization assistance program a growing number of policies and programs aim to increase investment in energy efficiency because conventional wisdom suggests that people fail to take up these investments even though they have positive private returns and generate environmental benefits many explanations for this energy efficiency gap have been put forward but there has been surprisingly little field testing of whether the conventional wisdom is correct this article reports on the results of an experimental evaluation of the nation s largest residential energy efficiency program the weatherization assistance program conducted on a sample of approximately 30 000 households in michigan the findings suggest that the upfront investment costs are about twice the actual energy savings furthermore the model projected savings are more than three times the actual savings although this might be attributed to the rebound effect when demand for energy end uses increases as a result of greater efficiency the article fails to find evidence of significantly higher indoor temperatures at weatherized homes even when accounting for the broader societal benefits derived from emissions reductions the costs still substantially outweigh the benefits the average rate of return is approximately 7 8 annually

a bilevel model for electricity retailers participation in a demand response market environment abstract demand response programmes are seen as one of the contributing solutions to the challenges posed to power systems by the large scale integration of renewable power sources mostly due to their intermittent and stochastic nature among demand response programmes real time pricing schemes for small consumers are believed to have significant potential for peak shaving and load shifting thus relieving the power system while reducing costs and risk for energy retailers this paper proposes a game theoretical model accounting for the stackelberg relationship between retailers leaders and consumers followers in a dynamic price environment both players in the game solve an economic optimisation problem subject to stochasticity in prices weather related variables and must serve load the model allows the determination of the dynamic price signal delivering maximum retailer profit and the optimal load pattern for consumers under this pricing the bilevel programme is reformulated as a single level milp which can be solved using commercial off the shelf optimisation software in an illustrative example we simulate and compare the dynamic pricing scheme with fixed and time of use pricing we find that the dynamic pricing scheme is the most effective in achieving load shifting thus reducing retailer costs for energy procurement and regulation in the wholesale market additionally the redistribution of the saved costs between retailers and consumers is investigated showing that real time pricing is less convenient than fixed and time of use price for consumers this implies that careful design of the retail market is needed finally we carry out a sensitivity analysis to analyse the effect of different levels of consumer flexibility

a note on environmental awareness and cross border pollution considering a nash equilibrium in which a developed country chooses the amount of foreign aid and a developing country sets the emission tax rate and the proportion of the received aid allocated to public abatement of pollution it is shown that an increase in the recipient country s environmental awareness will reduce the level of cross border pollution and benefits the donor though its foreign aid is increased

economic dispatch of demand response balancing through asymmetric block offers this paper proposes a method of describing the load shifting ability of flexible electrical loads in a manner suitable for existing power system dispatch frameworks the concept of an asymmetric block offer for flexible loads is introduced this offer structure describes the ability of a flexible load to provide a response to the power system and the subsequent need to recover the conventional system dispatch algorithm is altered to facilitate the dispatch of demand response units alongside generating units using the proposed offer structure the value of demand response is assessed through case studies that dispatch flexible supermarket refrigeration loads for the provision of regulating power the demand resource is described by a set of asymmetric blocks and a set of four blocks offers is shown to offer cost savings for the procurement of regulating power in excess of 20 for comparative purposes the cost savings achievable with a fully observable and controllable demand response resource are evaluated using a time series model of the refrigeration loads the fully modeled resource offers greater savings however the difference is small and potentially insufficient to justify the investment required to fully model and control individual flexible loads

foreign aid and public goods abstract most less developed countries ldcs use foreign economic aid to finance public consumption goods or public intermediate inputs this paper constructs a two country general equilibrium trade model where an income transfer that takes place between the two countries is used by the recipient to finance a public consumption good within this framework the paper identifies the conditions under which the income transfer improves or deteriorates the donor country s terms of trade and shows that the transfer can be welfare enriching for the donor and welfare immiserizing for the recipient country the paper also demonstrates that the transfer can raise reduce world welfare in which case a welfare increase decrease in both the donor and the recipient country is possible

assessing the impact of management buyouts on economic efficiency plant level evidence from the united kingdom we assess the total factor productivity of 35 752 manufacturing establishments before and after management buyouts mbos mbo plants are less productive than comparable plants before the transfer of ownership they experience a substantial increase in productivity after a buyout which appears to be due to measures undertaken by new owners to reduce the labor intensity of production via outsourcing of intermediate goods and materials these findings which are pervasive across industries imply that mbos reduce agency costs and enhance economic efficiency our evidence is consistent with jovanovic and rousseau 2002 who suggest that ownership changes shift resources to more efficient uses and to better managers

the fungibility of u s military and non military assistance and the impacts on expenditures of major aid recipients abstract this paper examines the impact of u s military and non military assistance on the allocation of public and private sector spending for eight major recipients over the 1972 1987 period the model assumes that an aid recipient s effective post assistance budget constraint is a priori unknown and must be estimated two versions of the model are tested in version a the data is converted into real u s dollars using official exchange rates in version b the data is converted using purchasing power parity exchange rates provided by summers and heston 1991 major findings are the same for both versions u s aid is highly fungible with a significant portion channeled to the private sector where it finances current consumption relatively more than investment

cross border pollution terms of trade and welfare we construct a two good general equilibrium model of international trade for two small open economies where pollution from production is transmitted across borders governments in both countries impose emission taxes non cooperatively within this framework we examine the effect of changes in the degree of cross border pollution on nash emission taxes emission levels and welfare we do so under two scenarios when changes in cross border pollution do not affect domestic pollution non strategic and when they do strategic we also examine the effect of changes in international terms of trade on pollution and welfare when cross border pollution is non strategic

a review on implementation strategies for demand side management dsm in kuwait through incentive based demand response programs abstract since the export of fossil fuel is the backbone of kuwait s economy the enormous upsurge in the internal fuel consumption creates anguish and bane at present 46 of the internal fossil fuel consumption is used for electricity generation the increase in fuel consumption hurled kuwait as one of the highest per capita electricity consuming as well as co 2 emitting countries in the world consumers pay only 6 of the production cost of electricity the government subsidizes the balance which is one of the major reasons behind the high electricity consumption in the country any reduction in electricity consumption can positively reflect on both per capita electricity consumption and co 2 emission additionally the saved fossil fuel can be exported to generate revenue to support the country s economy worldwide demand side management dsm is considered as an effective tool to curtail electricity demand the objective of this review paper is to explore the available literature to find out the most suitable dsm measures to control the growth of per capita electricity consumption in kuwait after conducting a detailed strengths weaknesses opportunities and threats swot analysis it is concluded that incentive based demand response programs can be considered as one of the most suitable solutions to address this problem

trade and pollution linkages piecemeal reform and optimal intervention we demonstrate how coordinated trade and environmental policy can achieve ef ficiency and pollution mitigation gains superior to those obtained without such coordination we show how trade and environment linkages give rise to complex second best policy issues and derive optimal interventions and sufficient conditions for welfare improving piecemeal trade and environmental policy reforms in a small economy changing trade and environ ment distortions in proportion to their optimal levels increases welfare we decompose the economic and environment effects of policies targeted at trade and pollution in both con sumption and production we also decompose production responses into output adjustments and changes in pollution intensities

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

green technology transfers and border tax adjustments we develop a two country general equilibrium model of foreign technology transfers tied to environmental clean up and border tax adjustments in the presence of transboundary pollution pollution is generated in the aid recipient as a by product in the production of a dirty good which it consumes as well as exports to the donor country in contrast to the literature which typically treats aid as a monetary transfer we assume that foreign aid consists of a transfer of environmental technology that lowers the cost of public clean up we also consider a border tax adjustment bta as a secondary policy instrument used in order to internalize the residual transboundary externality we study the environmental and welfare outcomes of the technology transfer and the bta as well as the interaction between the two policy instruments we derive conditions under which the additional presence of a bta may lead to a lower transfer and less public pollution abatement in the recipient with counter productive consequences for both the environment and welfare contrary to intuition we find that the green technology transfer and the border tax adjustment are not always complements

cross border mergers and acquisitions and the role of trade costs abstract cross border mergers and acquisitions m as have increased dramatically over the last two decades this paper analyses the role of trade costs in explaining the increase in the number of cross border m as in particular we distinguish horizontal and non horizontal m as and investigate whether trade costs affect these two types of mergers differently we analyse this question using industry data for 23 oecd countries for the period 1990 2001 our findings suggest that while in the aggregate trade costs affect cross border merger activity negatively its impact differs importantly across horizontal and non horizontal mergers the impact of trade costs is less negative for horizontal mergers which is consistent with the tariff jumping argument

methodology for the identification evaluation and prioritization of market handicaps which prevent the implementation of demand response application to european electricity markets this paper presents a methodology for the identification analysis and comparative assessment of the handicaps which nowadays prevent the higher implementation of demand response dr in the electricity market its application provides a hierarchical organization of handicaps from the most critical to the less critical and then from the easiest to the most difficult to overcome this makes possible to determine which barriers would be a priority which may indicate the direction of regulatory changes to properly address these handicaps and so stimulating a higher participation of the demand side in electricity markets after applying the methodology to three european countries 34 handicaps have been identified analyzing which of these handicaps affect such stakeholders as grid operators retailers and customers and how these stakeholders are affected for each handicap the criticality and difficulty to overcome the different handicaps have been studied based on detailed information coming from personal interviews to experts representing the different stakeholders in the electricity trading chain regulatory barriers have been identified as the most critical and difficult to overcome together with regulatory changes the promotion of aggregators and the training of customers on dr applications are some of the most significant initiatives

estimation of global rebound effect caused by energy efficiency improvement abstract rebound effect refers to the phenomenon that the actual reduction in energy use and emissions is less than the expected reduction caused by an energy efficiency improvement due to induced behavior adjustment of relevant economic agents this article studies the global rebound effects on energy use and related emissions caused by an energy efficiency improvement we adopt a global computable general equilibrium cge model to design a scenario of energy efficiency improvement which is compared to a business as usual bau scenario to identify the global rebound effect our results show very large rebound effect on energy use 70 and related emissions 90 in 2040 at the global level with regional and sectoral differences important determinants among others are induced labor movement among economic activities and labor supply and substitution elasticity between energy and other goods labor mobility has a marked impact on both rebound effects and on fuel mix the global rebound effect is still considerable even with a low substitution elasticity between energy and other goods the effect of capital accumulation over time contributes marginally to the global rebound effect as it is utilized to promote economic growth by using energy input more efficiently

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

consumer responses to time varying prices for electricity abstract we report new experimental evidence of the household response to weekday differentials in peak and off peak electricity prices the data come from auckland new zealand where peak residential electricity consumption occurs in winter for heating peak off peak price differentials ranged over four randomly selected groups from 1 0 to 3 5 on average there was no response except in winter in winter participant households reduced electricity consumption by at least 10 took advantage of lower off peak prices but did not respond to the peak price differentials response varied with house and household size time spent away from home and whether water was heated with electricity

evaluating the impacts of real time pricing on the cost and value of wind generation one of the costs associated with integrating wind generation into a power system is the cost of redispatching the system in real time due to day ahead wind resource forecast errors one possible way of reducing these redispatch costs is to introduce demand response in the form of real time pricing rtp which could allow electricity demand to respond to actual real time wind resource availability using price signals a day ahead unit commitment model with day ahead wind forecasts and a real time dispatch model with actual wind resource availability is used to estimate system operations in a high wind penetration scenario system operations are compared to a perfect foresight benchmark in which actual wind resource availability is known day ahead the results show that wind integration costs with fixed demands can be high both due to real time redispatch costs and lost load it is demonstrated that introducing rtp can reduce redispatch costs and eliminate loss of load events finally social surplus with wind generation and rtp is compared to a system with neither and the results demonstrate that introducing wind and rtp into a market can result in superadditive surplus gains

foreign aid and the question of fungibility this paper analyzes whether the foreign assistance provided for specific categories of expenditure is shifted among them contrary to the wishes of donors it also considers whether aid reduces the tax effort of recipient governments econometric results are presented for the dominican republic that show that the fungibility of aid has resulted in a thwarting of the intentions of donors an attempt is made to account for the observed differences in behavior of individual countries in altering expenditures copyright 1993 by mit press

integration scenarios of demand response into electricity markets load shifting financial savings and policy implications abstract demand response allows for the management of demand side resources in real time i e shifting electricity demand according to fluctuating supply when integrated into electricity markets demand response can be used for load shifting and as a replacement for both control reserve and balancing energy these three usage scenarios are compared based on historic german data from 2011 to determine that load shifting provides the highest benefit its annual financial savings accumulate to 3 110 m for both households and the service sector this equals to relative savings of 2 83 compared to a scenario without load shifting to improve demand response integration the proposed model suggests policy implications reducing bid sizes delivery periods and the time lag between market transactions and delivery dates in electricity markets

assessment of transformation strategies for the german power sector under the uncertainty of demand development and technology availability abstract the long term energy strategy issued by the german government in 2010 and 2011 embraces a substantial reduction of co 2 emissions and high shares of renewable energy in electricity production along with energy efficiency improvements and an accelerated nuclear phase out while several studies illustrate scenarios reaching these targets there are substantial uncertainties pertaining to key assumptions particularly long term electricity demand and the large scale availability of offshore wind and carbon capture and storage ccs this paper explores conditions under which model based scenarios for the german electricity sector comply with the official targets for co 2 emission reductions and renewable shares we apply the energy system model limes d which allows for a joint optimization of generation and transmission capacities the results indicate that reducing electricity demand plays a crucial role for attaining the government s targets scenarios for which either offshore wind or ccs is not available show an even stronger need for a decreasing electricity demand to reach the targets and a different pattern of transmission capacity expansion than is the case with full technology availability hence a broad technology portfolio could in turn hedge against future power demand increases that may challenge the joint attainment of the german decarbonization and renewable energy targets

competition for environmental aid and aid fungibility abstract aid from environmentally conscious donors to developing recipients has long been thought of as a very promising way of preserving the global environment however aid is fungible and recipients cannot commit to using it for the purpose it was intended we analyze competition for aid games with aid fungibility and cross border pollution to gain insights on how to allocate environmental aid more efficiently we set up a two stage game of two recipients receiving aid from a donor interested in minimizing pollution recipients cannot commit on the use of aid but they can commit on the infrastructure necessary to use aid for pollution abatement we find that the success of competition for aid games depends critically on the degree of cross border pollution this determines whether it is more efficient to set up such games between recipients with little or a lot of cross border pollution between them
