causalities between co2 electricity and other energy variables during phase i and phase ii of the eu ets the topic of this article is the analysis of the interplay between daily carbon electricity and gas price data with the european union emission trading system eu ets for co2 emissions in a first step we have performed granger causality tests for phase i of the eu ets january 2005 until december 2007 and the first year of phase ii of the eu ets 2008 the analysis includes both spot and forward markets given the close interactions between the two sets of markets the results show that during phase i coal and gas prices through the clean dark and spark spread impacted co2 futures prices which in return granger caused electricity prices during the first year of the phase ii the short run rent capture theory in which electricity prices granger cause co2 prices prevailed on the basis of the qualitative results of the granger causality tests we obtained the formulation testable equations for quantitative analysis standard ols regressions yielded statistically robust and theoretically coherent results

lobbying by capital and labor over trade and labor market policies abstract this paper uses the common agency approach to analyze the joint determination of product and labor market distortions in a small open economy capital owners and union members lobby the government on both tariffs and minimum wages while other factors of production are not organized the paper shows that product and labor market distortions always move in the same direction and that their level is not modified by social pacts between capital and labor it also shows that labor market distortions are second best hence conditionality by foreign organizations should target distortions in product markets but not in labor markets

estimating elasticities of substitution with nested ces production functions where do we stand abstract prompt by an increasing interest by climate change modelers a rich literature estimating elasticities of substitution in a nested ces production framework has recently developed this article reviews such literature we critically describe the nesting structures estimation approaches data sources and aggregation econometric techniques and types of substitution elasticities used by previous literature to offer a comprehensive description of the various options available to a researcher attempting this estimation we also provide suggestions for potential improvements to the estimation process in particular we warn researchers to use ces production functions with caution in empirical applications given their restrictive build in assumptions

strikes and political activism of trade unions theory and application to bangladesh the behavior of bangladeshi trade unions is characterized bypolitical activism and momentous strikes called hartalsthere have played a crucial part in most political changes inthis country we offer a theoretical framework for discussingthis fact and we test empirically its main prediction bybringing out the political cycle that characterizes theoccurrence of strikes in bangladesh

unions and strikes with asymmetric information strikes seem to be a pareto inefficient outcome of bargaining between a union and a firm however this paper shows that strikes can be the outcome of rational behavior by both agents if the firm has more information than the union concerning the state of nature the union can use strikes as a way of gaining information the paper uses an asymmetric information model where the firm has information about the state i e profitability that the union does not know the schedule of wage offers by the union then depends on the probability that a given state will occur

privatization deregulation and capital accumulation author affiliation gerhard glomm department of economics indiana university wylie hall room 105 bloomington in 47405 usa gglomm indiana edufabio mendez department of economics walton college of business room 402 university of arkansas fayetteville ar 72701 usa fmendez uark edu corresponding author acknowledgment we are grateful to b ravikumar rowena pecchenino jeffrey wooldridge felix rioja stefan krause and seminar participants from the economics department at emory university for useful observations we are also grateful to cristian opazo and javier reyes for their assistance and to the editor and two anonymous referees for helpful comments 1 introductionsince the early 1980s many countries have privatized and deregulated intermediate goods industries such as gas electricity or telecommunications that had traditionally been run by public monopolies the european union eu for example has adopted aggressive policies toward the elimination of monopolies in the telecommunication market and conducted a general privatization program whose sales receipts amounted to more than 3 of gdp between 1985 and 1995 constantinou and lagoudakis 1996 parker 1998 in other regions of the world countries like australia chile brazil argentina and the united states have implemented similar policies vickers and yarrow 1991 winston 1993 van der vlies 1996 while there is a large literature studying the microeconomic effects of privatization and deregulation the long run macroeconomic effects of such types of reforms have been subject to relatively less scrutiny in this paper we use a model of capital accumulation in order to investigate the long run effects of privatization and deregulation this paper complements a small literature that includes parente and prescott 1999 2000 schmitz 2001 and herrendorf and teixeira 2004 parente and prescott 1999 2000 and herrendorf and teixeira 2004 study the impact of monopoly rights on long run levels of income and find that the effect is large the latter authors find for example that monopoly rights can reduce aggregate income in the long run by a factor of seven schmitz 2001 uses a two sector model to calculate the impact of government production of investment goods on long run levels of labor productivity he finds that government production can lower labor productivity levels in the long run by about 30 our approach differs from herrendorf and teixeira 2004 who infer the extent of monopoly power from differentials in the relative prices of nontradeables instead we take the approach that monopoly power is likely to arise and exist in the public production of intermediate goods such as public utilities or telecommunication and that the size of these sectors relative to the rest of the economy can be directly estimated see world bank 1995 our approach also differs from schmitz 2001 in a fundamental way because he abstracts completely from the issue of monopoly rights in his model the only difference between the public and private production is that the government is endowed with a less productive technology than the private sector the long run income gains from privatization and deregulation in our paper are similar in magnitude to those found in schmitz 2001 in our base case calculation the long run income gain of changing from a public sector monopoly to a competitive market with private firms is 18 these welfare gains can be larger when there has been relatively low governmental investment in the public sector capital and when the elasticity of substitution between the intermediate input and physical capital is small like schmitz 2001 we view our results as less pertinent for rich economies like the united states where public sector involvement in intermediate good production is relatively small rather we view the results of our model as being applicable mostly to least developed countries ldcs such as egypt where governments typically play a large role in intermediate goods production

how competitive are eu electricity markets an assessment of ets phase ii this paper studies the interactions between electricity and carbon allowance prices in the year ahead energy markets of france germany united kingdom and the nordic countries during phase ii of the eu ets var and granger causality methods are used to analyze causal interfaces whereas the volatility of electricity prices is studied with basic and asymmetric ar garch models among the main results the marginal rate at which carbon prices feed into electricity prices is shown to be ca 135 in the eex and nord pool markets where electricity and carbon prices display bidirectional causality and 109 in the uk therefore generators in these markets internalized the cost of freely allotted emission allowances into their electricity prices considerably more than the proportionate increase in costs justified by effective carbon intensity moreover electricity prices in france are found to granger cause the carbon price this study also shows how european electricity prices are deeply linked to coal prices among other factors both in terms of levels and volatility regardless of the underlying fuel mix and that coal was marginally more profitable than gas for electricity generation eu policies aimed at increasing the carbon price are likely to be crucial in limiting the externalities involved in the transition to a low carbon system

a reexamination of the role of thermodynamics for environmental economics abstract as the discussion about the role of thermodynamics in environmental economics has not led to a conclusion yet a more fundamental approach seems to be necessary which also takes into consideration the relationship between economics and the natural sciences in general to this end value theory is chosen as a starting point because it is the centerpiece of every economic theory it is shown that neoclassical environmental economics suffers from serious deficiencies because of its value concept heedlessly copied from classical mechanics thermodynamics can be expected to be helpful to redress these defects because the economy can be thought of as a dissipative structure dependent on its environment the obvious way to integrate thermodynamics consists in the formulation of thermodynamic constraints to complement neoclassical environmental economics but this approach remains unsatisfactory because the neoclassical mechanical hardcore is incompatible with the entropy law and its implications evidently the neoclassical paradigm and its value concept have to be given up but the alternative of the energy theory of value must be rejected because its determinism cannot be reconciled with the richness of human behaviour as thermodynamic analogies offer no solution either there is a dilemma between the necessity and the apparent impossibility of adequately integrating thermodynamic concepts it turns out that a normative inconsistency is responsible which is due to the demand for intergenerational justice therefore the integration of thermodynamics into environmental economics hinges on a meta economic value decision if sustainability is adopted as the guiding principle the insights of thermodynamics call for a macro economic environmental policy setting absolute limits to the economy but this macro policy is incompatible with neoclassical economics so that a social reconstruction of economics based on a social theory of value becomes necessary in sum thermodynamics is important for environmental economics besides fulfilling a general heuristic function it also fulfils a decisive conceptual and an analytical function insofar as it helps to justify sustainability and to operationalize macro economic environmental policy

path dependency and input substitution implications for energy policy modelling in most policy oriented energy models the effectiveness of energy policy instruments crucially depends both on the values of the substitution elasticities between the various inputs and on the rates of technological progress in this paper we argue that due to the fixed cost nature of adjustments to relative price changes these technological parameters are affected by past developments failing to account for the role of history will result in biased parameter estimates and hence the implication for energy policy modelling is that the estimation period should be carefully selected we provide an empirical illustration using data for the netherlands

organized labor and the political economy of product market distortions why are economic reforms reversed through strikes and demonstrations in some countries but backed by the labor movement in other countries why do product and labor market distortions differ so much across countries this article addresses these questions by means of a simple heuristic model of the economy that replicates in an integrated manner several independent results from the recent political economy literature unlike most of this literature however the model focuses on the role played by organized labor rather than by rent seeking firms and guilds a two stage game between the government and organized labor determines the level of product market distortions for example import tariffs in the first stage the players may undertake costly actions such as redistributing income or striking in order to increase their bargaining power in the second stage they negotiate over product market distortions and wages under very general assumptions several policy regimes exist changes in the key parameters of the economy may trigger a switch in the strategy of trade unions from confrontation to cooperation and hence change the policy regime cross country data highlight that in spite of its simplicity the model reproduces some observed empirical regularities

fossil fuel subsidy reforms and their impacts on firms abstract while the potential adverse effects of fossil fuel subsidy reform are well documented for households the literature has largely ignored the effect of subsidy reform on firms competitiveness this paper discusses how firms are affected by and respond to energy price increases caused by subsidy reforms it highlights that cost increases both direct and indirect do not necessarily reflect competitiveness losses since firms have various ways to mitigate and pass on price shocks this paper presents and discusses direct and indirect transmission channels for price shocks and firms response measures absorbing cost shocks into profits inter fuel substitution increasing energy and material efficiency and passing on price increases it argues that further micro econometric studies using enterprise surveys are essential for quantifying the role of these mechanisms and for designing policy measures that ensure that competitiveness losses due to subsidy reforms are minimised

what do we know about carbon taxes an inquiry into their impacts on competitiveness and distribution of income abstract the kyoto protocol to the united nations framework convention on climate change unfccc has set legally binding emissions targets for a basket of six greenhouse gases and timetables for industrialised countries it has also incorporated three international flexibility mechanisms however the articles defining the flexibility mechanisms carry wording that their use must be supplemental to domestic actions this has led to the open debates on interpretations of these supplementarity provisions such debates ended at the resumed sixth conference of the parties cop to the unfccc held in bonn july 2001 and at the subsequent cop 7 in marrakesh november 2001 the final wording in the bonn agreement reaffirmed in the marrakesh accords at least indicates that domestic policies will have an important role to play in meeting annex b countries emissions commitments carbon taxes have long been advocated because of their cost effectiveness in achieving a given emissions reduction in this paper the main economic impacts of carbon taxes are assessed based on a review of empirical studies on existing carbon energy taxes it is concluded that competitive losses and distributive impacts are generally not significant and definitely less than often perceived however given the ultimate objective of the framework convention future carbon taxes could have higher rates than those already imposed and thus the resulting economic impacts could be more acute in this context it has been shown that how to use the generated fiscal revenues will be of fundamental importance in determining the final economic impacts of carbon taxes finally we briefly discuss carbon taxes in combination with other domestic and international instruments

fossil fuel subsidy removal and inadequate public power supply implications for businesses abstract we briefly consider the impact of fossil fuel subsidy removal policies in the context of inadequate power supply with a focus on the implications for businesses in doing so we utilize the case of the early 2012 fuel subsidy removal in nigeria the rationale for such subsidy removal policies is typically informed by analysis showing that they lead to an economically inefficient allocation of resources and market distortions while often failing to meet intended objectives however often the realities of infrastructural and institutional deficiencies are not appropriately factored into the decision making process businesses in many developing countries already impaired by the high cost of power supply deficiencies become even less competitive on an unsubsidized basis we find that justifications for removal often do not adequately reflect the specific environments of developing country economies resulting in poor recommendations or ineffective policy

how substitutable is natural capital one of the recurring themes in the sustainability literature has been the extent to which a loss of natural capital can be made up for in welfare terms by an increase in other forms of capital this issue was raised early on in the debate on sustainability by pearce and has never really been resolved this paper is an empirical attempt to measure the degree of substitutability between different forms of capital a nested ces production function is used to allow flexibility in the estimated elasticities of substitution also within this specification natural resources and other inputs are combined in different levels of the function thus allowing for different levels of substitutability institutional and economic indicators are also incorporated in the production function estimated results show that the elasticities derived from functions involving land resources were generally around one or greater implying a fairly high degree of substitutability furthermore changes in trade openness and private sector investment have a statistically significant and direct relationship on the efficiency of production and hence on income generation no statistically significant relationship between income and any of the institutional indicators was found

production functions for climate policy modeling an empirical analysis abstract quantitative models for climate policy modeling differ in the production structure used and in the sizes of the elasticities of substitution the empirical foundation for both is generally lacking this paper estimates the parameters of 2 level ces production functions with capital labour and energy as inputs and is the first to systematically compare all nesting structures using industry level data from 12 oecd countries we find that the nesting structure where capital and labour are combined first fits the data best but for most countries and industries we cannot reject that all three inputs can be put into one single nest these two nesting structures are used by most climate models however while several climate policy models use a cobb douglas function for part of the production function we reject elasticities equal to one in favour of considerably smaller values finally we find evidence for factor specific technological change with lower elasticities and with factor specific technological change some climate policy models may find a bigger effect of endogenous technological change on mitigating the costs of climate policy

capital energy substitution and the multi level ces production function abstract this paper has clarified a misconception in sato s multi level ces production function and used the function in testing for capital energy substitution in taiwanese manufacturing the empirical results show that capital and energy are substitutes and the aes estimates differ little from those derived from the translog approximation

china s energy economy technical change factor demand and interfactor interfuel substitution with its rapid economic growth china s primary energy consumption has exceeded domestic energy production since 1994 leading to a substantial expansion in energy imports particularly of oil china s energy demand has an increasingly significant impact on global energy markets in this paper allen partial elasticities of factor and energy substitution and price elasticities of energy demand are calculated for china using a two stage translog cost function approach the results suggest that energy is substitutable with both capital and labor coal is significantly substitutable with electricity and complementary with diesel while gasoline and electricity are substitutable with diesel china s energy intensity is increasing during the study period 1995 2004 and the major driver appears to be due to the increased use of energyintensive technology

on doctors mechanics and computer specialists the economics of credence goods most of us need the services of an expert when our apartment s heating or our washing machine breaks down or when our car starts to make strange noises and for most of us commissioning an expert to solve the problem causes concern this concern does not disappear even after repair and payment of the bill on the contrary one worries about paying for a service that was not provided or receiving some unnecessary treatment this article studies the economics underlying these worries under which conditions do experts have an incentive to exploit the informational problems associated with markets for diagnosis and treatment what types of fraud exist what are the methods and institutions for dealing with these informational problems under which conditions does the market provide incentives to deter fraudulent behavior and what happens if all or some of those conditions are violated

settlement in tax evasion prosecution it is often argued that even if optimal ex post settlement dilutes deterrence ex ante we analyse the interest for the tax authority of committing ex ante to a settlement strategy we show that to commit to the use of settlements is ex ante optimal when the tax authority receives signals that provide statistical information about the taxpayers true tax liability the more informative the signal the larger the additional expected revenue raised by the tax authority when using settlement as a policy tool

interfuel substitution a meta analysis interfuel substitutability has been of longstanding interest to the energy economics and policy community however no quantitative meta analysis has yet been carried out of this literature this paper fills this gap by analyzing a broad sample of studies of interfuel substitution in the industrial sector manufacturing industry or subindustries or macro economy of a variety of developed and developing economies publication bias is controlled for by including the primary study sample size in the meta regression results for the shadow elasticities of substitution between coal oil gas and electricity for forty six primary studies show that at the level of the industrial sector there are easy substitution possibilities between all the fuel pairs with the exception of gas electricity and coal electricity substitution possibilities seem more constrained at the macro level and less constrained in sub industries estimates also vary across countries publication bias does not seem to be present but model and data specification issues very significantly affect the estimates derived by each individual study estimates from cross section regressions are generally largest fixed effects panel estimates intermediate in magnitude and time series estimates are mostly much smaller econometric research suggests that the fixed effects estimates are likely the best among the existing studies though biased downwards

a nested ces approach to capital energy substitution abstract this paper uses the nested constant elasticity of substitution ces production function to estimate elasticities of substitution between capital labour energy and materials over the 1971 1976 period around the initial energy crisis elasticities are estimated for each of the two digit sic industries within us manufacturing using more disaggregate four digit sic data the nested ces function makes it possible to distinguish between engineering and economic elasticities of substitution capital and energy are estimated to be slight engineering substitutes and economic complements labour energy and materials are estimated economic substitutes

atheoretical macroeconometrics a critique abstract the spurious nature of the restrictions used to identify many macroeconometric models has led some researchers to advocate a style of econometric inquiry that is less dependent on prior theoretical restrictions of the sort that were central to the approach of the cowles commission this development which we call atheoretical macroeconometrics is summarized and evaluated in the current paper it is contrasted with an updated version of the cowles commission approach we conclude that while some of the exercises of atheoretical macroeconometrics are valid those that have attracted the most attention and appear the most innovative exogeneity testing impulse response analysis and policy analysis using estimated vector autoregressions are based on incorrect analysis

honesty in a model of strategic information transmission we consider the following simple model of consumer fraud consumers need one of two possible repairs an expensive repair denoted e or an inexpensive repair denoted i the exogenous probability that a consumer needs the more costly remedy is r each consumer is assumed to know r an expert can observe with certainty which of the two repairs is needed and can offer to sell either to the consumer in a simple extension we allow for uncertainty with respect to the expert s observation we assume that selling the expensive remedy to a consumer who needs only the inexpensive one is more profitable than selling the inexpensive one thus h eii h1 iji where h denotes profit and i denotes conditional on needing the profit functions are increasing in the price of the respective repairs for convenience we suppress the dependence of h on prices in our notation we also assume that a consumer prefers to obtain the appropriate repair to the inappropriate one thus u eie u ije and u iii u eii where u is the consumer s payoff lastly we assume that the functions u eje and u e i are decreasing in the price of the expensive repair and that u iie and u iii are decreasing in the price of the inexpensive repair we also assume that u iie is decreasing in the price of the expensive repair since the consumer ultimately buys the expensive repair in this case see below for further assumptions regarding the repairs we are interested in the equilibrium levels of honesty in this model how honest is the expert at the equilibrium do consumers always follow the expert s advice does the level of honesty increase as the interests of the agents become more similar in a sense to be defined below our assumptions are similar to those in the abstract strategic information transmission models of vincent crawford and joel sobel 1982 and jerry green and nancy stokey 1980 we follow the former paper which asks whether the signals sent become less noisy as the agents preferences become more similar despite the similarity of our model to crawford sobel s we arrive at some different conclusions with respect to the expert s honesty vis a vis the agents closeness of interests we explain this in detail in section iii in addition we allow that the expert may be uncertain about the true state of the world we also explicitly model the level of expert honesty which extends crawford sobel the outline of the paper is as follows in section i we provide the details of the model and show that a unique equilibrium exists comparative static results and a simple extension incorporating the assumption of the incompetent expert are given in section ii we draw comparisons with crawfordsobel in section iii in section iv we conclude with a brief summary

structural optimization and carbon taxation in china s commercial sector abstract given china s economic transformation and upgrading process the green development of commercial sector is more and more important based on the trans log cost function this paper calculates the inter factor and inter fuel substitution effects in china s commercial sector from 1980 to 2016 besides the paper further analyzes the driving factors of the dynamic changes in energy intensity and the impact of carbon taxation in china s commercial sector the main conclusions are as follows 1 capital labor and energy in china s commercial sector negatively correlate with their prices and the self price elasticities of energy labor and capital decline in turn 2 the relationship between labor and capital is substitutional and the same relationship is found when after considering labor and energy and that between energy and capital is complementary 3 demand for energy sources negatively correlates with their prices and there exist complementary relationships between energy sources 4 technical effects and substitution effects can effectively promote the decline of energy intensity in china s commercial sector 5 implementing a 50 rmb tonne carbon taxation will lead to 5 50 energy savings and 6 21 co2 reduction

the dynamics of pretrial negotiation it is shown that many cases proceed to court despite ample opportunity for interaction and much of the settlement takes place on the courthouse steps the deadline effect when fixed costs of bargaining are introduced a u shaped pattern of settlement appears with a greater chance of settlement at the beginning and at the end of negotiations than in the middle these characteristics persist even as the time between offers approaches zero the theoretical predictions are consistent with the stylized facts a large proportion of the lawsuits that are settled out of court are settled very close to the trial date or in the first several days of the trial 3 although the deadline effect appears in many other settings as well it has little theoretical support 4

an economic analysis on overbilling incentives and auditing programs an institutional auditing program typically consists of the following steps a sample audit the decision to move to the full audit a settlement offer and the full audit statistical sampling techniques are often used to estimate the overbilling percentage and amount this paper discusses the optimal settlement offer the net recovery through auditing the condition for the auditors to move to the full audit and how an auditing program can be truly cost effective this paper provides an evaluation for the statistical sampling techniques to an auditing program the economic incentives of a contractor to overbill are also identified finally it presents the key metrics and the managerial implications for auditing managers to design or enhance their auditing programs

incidence and impact the regional variation of poverty effects due to fossil fuel subsidy reform since fossil fuel subsidy reforms can induce significant distributional shifts and price shocks effective compensation and social protection programs are crucial based on the statistical simulation model by araar and verme 2012 this study estimates the regional variability of direct welfare effects of removing fuel subsidies in nigeria uncompensated subsidy removal is estimated to increase the national poverty rate by 3 4 on average however uniform cash compensation that appears effective at the national average is found to fail to mitigate price shocks in 16 of 37 states thus putting livelihoods and public support for reforms at risk states that are estimated to incur the largest welfare shocks coincide with hotspots of civil unrest following nigeria s 2012 subsidy reform attempt the study illustrates how regionally disaggregated compensation can be revenue neutral and maintain or reduce pre reform poverty rates in all states overall it highlights the importance of understanding differences in vulnerability and designing tailored social protection schemes which ensure public support for subsidy reforms

household heterogeneity impact of removing energy subsidies in china direct and indirect effect abstract reforming subsidies for fossil fuels is a challenging prospect for many governments the impact of such a reform on households is a major concern for the government this paper investigates the heterogeneous impacts of eliminating energy subsidies on households in china from direct and indirect perspectives the results of the direct effects show that the removal of energy subsidies particularly for removing electricity and gas subsidies has a greater negative impact on the poor than on the rich from an indirect perspective this article shows that the lower the per capita disposable income the higher the proportion of consumption to disposable income and the greater the indirect impact of eliminating subsidies meanwhile the impact is not only related to household income but consumer goods moreover the indirect effects of eliminating subsidies on households differ across energy types specifically eliminating electricity subsidies has the greatest effect on households followed by transportation fuel and gas we suggest that targeted supportive measures need to be taken towards the implementation of subsidy reform particularly in countries with greater inequality to minimize the negative effects on the poor

incumbent performance and electoral control in the pure theory of electoral competition citizens compare the platforms of the candidates and vote for the one whose platform is preferred candidate strategies are identified with promises about future performance in office models of this sort have been developed in both static mckelvey 1975 and dynamic kramer 1977 i settings and all appear to have the property that if the set of alternatives is large enough in some sense equilibrium platforms rarely exist but these models have another feature that is quite as disturbing as their instability in the static setting discussed by mckelvey little attention is paid to the possibility that once in office the politician s preferences may diverge from those of his constituents and that he may therefore choose policies at variance from his platform instead it is simply assumed that promises will be kept whether or not such behavior is congruent with the interest of the officeholder it is sometimes argued that an enforcement mechanism may exist to discipline politicians for failing to keep promises but without a specification of the mechanism it is not obvious that it would be in the interests of the

economic reform and labor unions a general equilibrium analysis applied to bangladesh and indonesia noting the trend toward more independent trade unions in developing countries this article examines whether the presence of unions strengthens or weakens the benefits to be gained from economic policy reform we show that the presence of passive unions ones that choose their wage employment contract given the firm s cost minimizing strategy increases the welfare gains from trade liberalization because trade reform lowers the wage premium enjoyed by the unionized sector reducing a distortion in the labor market these gains are amplified when the unions are active namely when they negotiate a contract with the firm that is off its labor demand curve such a contract results in featherbedding paying workers more than their marginal product and trade reform reduces the amount of featherbedding the policy implication for bangladesh a country with strong trade unions and a protected unionized sector is that the benefits of further trade liberalization may be greater than otherwise predicted in indonesia where both unionization and import tariffs are low allowing greater independence to unions may preserve flexibility and reward workers better than the current minimum wage policy

the unequal benefits of fuel subsidies a review of evidence for developing countries summary this paper reviews evidence on the impact of fuel subsidy reform on household welfare in developing countries on average the burden of subsidy reform is substantial and is approximately neutrally distributed across income groups a 0 25 decrease in the per liter subsidy results in a 5 decrease in income for all groups more than half of this impact arises from the indirect impact on prices of other goods and services consumed by households fuel subsidies are a costly approach to protecting the poor due to substantial benefit leakage to higher income groups in absolute terms the top income quintile captures six times more in subsidies than the bottom

good subsidies or bad subsidies evidence from low carbon transition in china s metallurgical industry abstract since the metallurgical industry has become the main source of china s carbon dioxide emissions and energy consumption in recent years low carbon transition in that industry is of great significance for achieving china s carbon reduction targets it is generally believed that phasing out fossil fuel subsidies is an effective way to reduce energy related co2 emissions since it can increase the energy prices and lower its consumption this paper aims to investigate whether the energy subsidy removal can promote the low carbon transition of china s metallurgical industry taking inter fuel and inter factor substitution effects as the link we calculate the co2 mitigation potential on the assumption that the subsidies for each category of fossil energy were eliminated we find that the metallurgical industry has a sluggish reaction to the changes in energy price supposing eliminating the energy subsidies in the period of 2003 2015 the amount of reduced co2 would be 487 286 million tons accounting for a slight proportion of the total emissions in the industry but it is meaningful for the global co2 mitigation since it approximates the whole co2 emissions in norway during the same period these findings can provide some new insights for the energy subsidy issue and suggest that the additional measures are required to promote the low carbon transition in china s metallurgical industry rather than just relying on the removal of fossil fuel subsidies

impacts of removing fuel import subsidies in nigeria on poverty abstract the petroleum sector contributes substantially to the nigerian economy however the potential benefits are diminished due to the existence of significant subsidies on imports of petroleum products subsidies on imported petroleum products are considered to be an important instrument for keeping fuel prices and hence the cost of living low the costs of these subsidies however has risen dramatically in recent years due to increased volatility in world petroleum and petroleum product prices and increased illegal exportation of subsidized petroleum products into neighboring countries removing the subsidy on fuel is one of the most contentious socio economic policy issues in nigeria today in this paper an economy wide framework is used to identify the impact of removing the fuel subsidy on the nigerian economy and investigates how alternative policies might be used to meet socio economic objectives related to fuel subsidies the results show that while a reduction in the subsidy generally results in an increase in nigerian gdp it can have a detrimental impact on household income and in particular on poor households accompanying the subsidy reduction with income transfers aimed at poor households or domestic production of petroleum products can alleviate the negative impacts on household income

strikes are more common in countries with majoritarian electoral systems strikes are more common in those oecd countries where the legislature is elected in single member districts smd than in those where it is elected by proportional representation pr furthermore more working days are lost due to industrial conflict in countries with smd i suggest a politico economic explanation for these rarely noticed empirical regularities further empirical testing including controls drawn from previous strike research reveals that they hold up in a variety of econometric specifications

litigation and settlement under two sided incomplete information this paper deals with a simple game of litigation and settlement with incomplete information parties are assumed to have the choice between settling their dispute out of court or resorting to costly litigation the set of sequential equilibria is characterized and conditions are given under which an efficient equilibrium does exist efficient equilibria however will be ruled out by various tests of refinement a comparative statics analysis is carried out with respect to the quality of private information which parties are assumed to receive before any moves have to be made

discretion in tax enforcement this paper deals with the issue of whether the revenue service rs should be allowed or even encouraged to negotiate settlement agreements with taxpayers subject to examination we consider the case in which the rs enjoys discretion at the settlement stage its stance being guided by officers professional judgment we show that discretionary settlements serve a desirable function as they allow the rs to better exploit taxpayer specific information and to take advantage of the bargaining power it can wield at the negotiation stage

the economic effects of energy price shocks large fluctuations in energy prices have been a distinguishing characteristic of the u s economy since the 1970s turmoil in the middle east rising energy prices in the u s and evidence of global warming recently have reignited interest in the link between energy prices and economic performance this paper addresses a number of the key issues in this debate what are energy price shocks and where do they come from how responsive is energy demand to changes in energy prices how do consumers expenditure patterns evolve in response to energy price shocks how do energy price shocks affect u s real output inflation and stock prices why do energy price increases seem to cause recessions but energy price decreases do not seem to cause expansions why has there been a surge in the price of oil in recent years why has this new energy price shock not caused a recession so far have the effects of energy price shocks waned since the 1980s and if so why as the paper demonstrates it is critical to account for the endogeneity of energy prices and to differentiate between the effects of demand and supply shocks in energy markets when answering these questions

estimated substitution elasticities of a nested ces production function approach for germany this paper demonstrates an econometric estimation of substitution elasticities of a nested constant elasticity of substitution production function ces between capital energy and labour for the west german industry in the last few years ces production functions have become more important in economic modelling especially for applied general equilibrium models where ces production functions are an important building stone in the literature different results of estimated elasticities can be found this paper investigates three different approaches for nested ces production functions and their estimated substitution elasticities capital energy and labour are estimated as substitutes for the west german industry in the long run

an empirical test of an asymmetric information model of strikes recent developments in the theory of strategic bargaining demonstrate how informational asymmetries can lead to prolonged and costly bargaining these models can be applied to contract negotiations yielding an economic theory of strikes to date however few empirical tests of these models have been carried out in this paper a set of predictions concerning the incidence and unconditional duration of strikes is derived from a simple bargaining model in which the union is uncertain about the firm s future profitability these predictions are then tested on a micro data set of major u s contract negotiations that took place from 1973 to 1977

energy conservation in electricity generation a case study of the electricity and water industry in kuwait this paper has examined possibilities of energy conservation in the generation of electricity and water in kuwait this has been done through analysing the underlying production structure by employing a translog flexible cost function and using series data the results show that in the absence of changes in factor prices fuel intensity of electricity and water is expected to increase with increase in output furthermore capital and fuel are found to be substitutes overall the evidence suggests that energy conservation can be achieved by using fuel prices as instruments this is likely to induce demand for new capital and hence promote productivity gains

economic performance of flexible functional forms flexible functional forms are well behaved over restricted regions the outer domain and constitute good approximations of a hypothetical true technology set of preferences over only a subregion of the outer domain the inner domain comparison of such forms has been made in terms of outer domain ideally il should also cover the inner domain by definition however the inner domain is unquantifiable instead functions representing producer technology consumer preferences can be characterized and compared in terms of what we call in this paper economic performance focusing on the producer side we demonstrate that relative differences and associated implications for equilibrium modeling can be substantial

capital stock labor energy substitution and production efficiency study for china abstract this study estimates the elasticities of substitution for china from 1953 to 2006 by the two level constant elasticity of substitution ces production function with three factor inputs capital stock labor and energy a technological change rate and non constant returns to scale are under considered all possible combinations and two other subdivided periods are carried out respectively and their technological change rates elasticities of substitution and returns to scale are found this study also provides an analysis of production efficiency by using marginal productivity of specific factor input according to the estimated results and distinguishes the marginal productivities deriving from the three different combinations it suggests that the decision makers of china need to consider the effects of different factor inputs on gdp growth

rents in the european power sector due to carbon trading abstract the european union emissions trading scheme eu ets has imposed a price on the allowances for co2 emissions of electricity companies integrating this allowance price into the price of electricity earns a rent for companies who have received these allowances for free during phase i 2005 2007 rents corresponding to the aggregate value of allocated allowances amounted to roughly 13 billion per year however due to the specific price setting mechanism in electricity markets true rents were considerably higher this is due to the fact that companies also that have not received any allowances gain additional infra marginal rents to the extent that their variable costs are below the new market price after inclusion of the allowance price producers with low carbon emissions and low marginal costs thus also benefit substantially from carbon pricing this paper develops a methodology to determine the specific interaction of the imposition of such a co2 constraint and the price setting mechanism in the electricity sector under the assumption of marginal cost pricing in a liberalized european electricity market the article thus provides an empirical estimate of the true total rents of power producers during phase i of the eu ets 2005 2007 the eu ets generated in phase i additional rents in excess of 19 billion per year for electricity producers these transfers are distributed very unevenly between different electricity producers in a second step the paper assesses the impact of switching from free allocation to an auctioning of allowances in 2013 we show that such a switch to auctioning will continue to create additional infra marginal rents for certain producers and will leave the electricity sector as a whole better off than before the introduction of the eu ets

the impact of increased efficiency in the industrial use of energy a computable general equilibrium analysis for the united kingdom the conventional wisdom is that improving energy efficiency will lower energy use however there is an extensive debate in the energy economics policy literature concerning rebound effects these occur because an improvement in energy efficiency produces a fall in the effective price of energy services the response of the economic system to this price fall at least partially offsets the expected beneficial impact of the energy efficiency gain in this paper we use an economy energy environment computable general equilibrium cge model for the uk to measure the impact of a 5 across the board improvement in the efficiency of energy use in all production sectors we identify rebound effects of the order of 30 50 but no backfire no increase in energy use however these results are sensitive to the assumed structure of the labour market key production elasticities the time period under consideration and the mechanism through which increased government revenues are recycled back to the economy

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

asymmetric substitutability between energy and capital evidence from the manufacturing sectors in 10 oecd countries abstract this paper investigates the substitutability between energy and capital in the manufacturing sectors of ten oecd countries since 1980 by applying a cost function approach that has been widely used to analyze industrial energy demand first we attempt to determine the source of the disagreement in the literature on the substitutability between energy and capital and reach a conclusion regarding the substitutability between energy and capital dividing energy and capital into sub inputs we analyze their substitutability the empirical results indicate that fuel tends to complement capital in most countries whereas electricity and capital are substitutes thus this study confirms that heterogeneity in energy sources is a primary component of the systematic variation in the substitutability between energy and capital second we examine asymmetric substitutability between energy and capital by estimating the morishima elasticity of substitution the estimates of the morishima elasticity of substitution demonstrate that the substitution of energy for capital has dominated the substitution of capital for energy this asymmetric substitutability is natural from the producer perspective because capital costs are much greater than energy costs in most countries these results imply that the adoption of energy saving technologies has not been induced in response to increased energy prices

fuel switching as an option for medium term emission reduction a model based analysis of reactions to price signals and regulatory action in german industry abstract the german federal government has set a target for german industry to reduce its ghg emissions by 49 51 by 2030 compared to 1990 fuel switching to electricity and biomass is a potential measure to meet this target in this article we simulate the contribution of fuel switching by applying economic incentives and regulatory measures the policy instruments of a co2 price and technology specific subsidies are applied with varying intensity in addition we simulate accelerated stock replacement and a ban on new fossil based steam generation systems results show that combining fuel switching and energy efficiency could achieve emission reductions of 50 by 2030 compared to 1990 only combined with considerable economic pressure up to 300 tco2 and financial support for electricity based process heating we observe that neither a co2 price nor investment grants for electric process heating equipment are effective instead substantial reductions of electricity prices and accelerated stock replacement are effective levers meeting the german emissions target for industry increases the modelled system costs by 20 compared to a case without additional policies we conclude that an effective policy mix to incentivise fuel switching to electricity needs to address operating costs and stock replacement rather than capital expenditures
