the design of environmental markets what have we learned from experience with cap and trade this article reviews the design of environmental markets for pollution control over the past 30 years and identifies key market design lessons for future applications the focus is on a subset of the cap and trade systems that have been implemented planned or proposed around the world three criteria led us to the selection of systems for review first among the broader class of tradable permit systems our focus is exclusively on cap and trade mechanisms thereby excluding emission reduction credit or offset programmes second among cap and trade mechanisms we examine only those that target pollution abatement and so we do not include applications to natural resource management such as individual transferable quota systems used to regulate fisheries third we focus on the most prominent applications those that are particularly important environmentally economically or both

trading for the future signaling in permit markets abstract permit markets are celebrated as a policy instrument since they allow i firms to equalize marginal costs through trade and ii the regulator to distribute the burden in a politically desirable way these two concerns however may conflict in a dynamic setting anticipating the regulator s future desire to give more permits to firms that appear to need them firms purchase permits to signal their need this raises the price above marginal costs and the market becomes inefficient if the social cost of pollution is high and the government intervenes frequently in the market the distortions are greater than the gains from trade and non tradable permits are better the analysis helps to understand permit markets and how they should be designed

how efficient is the voting market it is by now well established that good macroeconomic conditions benefit the incumbent president and his congressional party confreres at the polls this result is not unanimous see for example stigler or arcelus and meltzer2 and may not be universal 3 however the basic results in kramer 4 the progenitor of the modern literature on the effect of economic conditions on elections seem to have stood the test of time the broad consensus of this literature is that voters in presidential and congressional elections 1 reward income growth and punish unemployment and inflation 2 probably give greater weight to income growth than to unemployment and inflation and 3 myopically ignore any information beyond the recent past say prior to the election year 5 so far however the data have outrun interpretation while economic conditions seem to matter we do not know why they matter or how plausibly to characterize the process by which voters translate information about economic conditions into voting decisions this article tries to fill that gap though it extends the empirical literature to gubernatorial elections its main con

on savings and investment dynamics in a small open economy abstract this paper constructs a stochastic overlapping generations two country model of savings and investment under conditions of perfect international capital mobility the focus of the analysis is on the relationship between savings and investment dynamics in a small open economy in response to stochastic variations in domestic and or foreign production technologies the model is simulated under alternative specifications of the stochastic distribution governing both technologies this provides insight into the very complicated nature and rich diversity of possible relationships between savings and investment dynamics

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

capture and ideology in the economic theory of politics the economic theory of regulation long ago put public interest theories of politics to rest these theories have correctly been viewed as normative wishings rather than explanations of real world phenomena they have been replaced by models of political behavior that are consistent with the rest of microeconomics anthony downs 1957 james buchanan and gordon tullock 1965 george stigler 1971 sam peltzman 1976 recently however debate has arisen over whether some version of a public interest theory of regulation will have to be readmitted to our thinking about actions and results in the political arena what is at issue is the empirical importance of the altruistic publicly interested goals of rational actors in determining legislative and regulatory outcomes james kau and paul rubin 1979 kalt 1981 peltzman 1982 this study assesses the nature and significance of publicly interested objectives in a particular instance of economic policymaking u s senate voting on coal strip mining regulations the existence of such objectives is of course no contradiction of the economic view of human behavior kenneth arrow 1972 gary becker 1974 and may well be rooted in genetic biological history becker 1976 jack hirshleifer 1978 generally however individuals altruistic publicly interested goals have been given little attention this reflects the judgment that such goals are so empirically unimportant as to allow the use of occam s razor in positive models or well founded apprehensions that these goals are unusually difficult to identify measure and analyze notwithstanding the latter problem we find that approaches which confine themselves to a view of political actors as narrowly egocentric maximizers explain and predict legislative outcomes poorly the tracking and dissecting of the determinants of voting on coal strip mining policy suggest that the economic theory of politics has been prematurely closed to a broader conception of political behavior

emissions trading with profit neutral permit allocations this paper examines the impact of an emissions trading scheme ets on equilibrium emissions output price market concentration and profits in a generalized cournot model we develop formulae for the number of emissions permits that have to be freely allocated to firms to neutralize the profit impact of the ets we show that its profit impact is usually limited in a cournot oligopoly with constant marginal costs total industry profits are preserved so long as freely allocated permits cover a fraction of initial emissions that does not exceed the industry s herfindahl index

cap and trade policy challenges a tale of three markets cap and trade policy instruments have been applied to a number of environmental problems with varying success this article examines cap and trade programs for so2 allowances fishery quotas and water rights design and implementation of cap and trade mechanisms involves challenging policy tradeoffs accommodating equity concerns balancing use levels with resource conditions facilitating transactions accounting for externalities assuring adequate monitoring and documenting welfare gains efficient trading mechanisms are more readily implemented when there is a strong political or legal mandate to cap resource use and trades are perceived as a means to ease adjustment to use limits

an interim evaluation of sulfur dioxide emissions trading ide iv of the 1990 clean air act amendments established the first large scale long term environmental program to rely on tradable emissions permitscalled allowances in this program to control pollution this program was designed to cut acid rain by reducing sulfur dioxide so2 emissions from electric generating plants to about half their 1980 level beginning in 1995 it is of interest both as a response to an important environmental issue and as a landmark experiment in environmental policy this experiment comes at a particularly important time since emission trading is under serious consideration with strong u s backing for use to deal with global climate change by curbing emissions of carbon dioxide co2 the economic stakes in climate change surpass those in acid rain by several orders of magnitude intergovernmental panel on climate change 1996 this article summarizes the results to date of our ongoing empirical analysis of compliance costs and allowance market performance under the u s acid rain program

capital mobility and the current account abstract this paper analyzes the effect of unanticipated changes in the terms of trade on consumption expenditures and the current account in a small open economy simple formulas are obtained for the covariances of changes in consumption expenditures the current account and the expected current account with changes in the terms of trade it is shown that if investment is uncorrelated with the terms of trade a necessary condition for unanticipated changes in the terms of trade to be correlated with changes in consumption expenditures and the expected current account is that the real expected return on foreign bonds differs from the real expected return on domestic bonds

the ems and the dollar the ems and the dollar francesco giavazzi and alberto giovannini this paper examines the behaviour of exchange rates prior to and since the inception of the european monetary system ems movements in bilateral european exchange rates tend to be associated with fluctuations in the dollar in particular the mark tends to appreciate against other european currencies when the dollar depreciates further most realignments of currencies in the ems have generally occurred after sharp movements in the dollar conventional explanations relying on portfolio diversification by investors do not seem to explain the facts fully a more satisfactory explanation is provided by the existence of capital controls these limit the mobility of assets and ensure an asymmetric response by european currencies to movements in the dollar these capital controls are in the absence of coordinated monetary policy essential to the smooth working of the ems however at the same time they limit the scope for the further integration of european capital markets thus the ems is not a step on the road to greater financial integration indeed it is a cul de sac

the benefits of spatially differentiated regulation the response to acid rain by u s states prior to the acid rain program location is a crucial driver of both the marginal abatement and damage costs of sulfur dioxide emissions by u s coal fired power plants before the start of the acid rain program in 1995 old boilers were subject to emission rate standards set by individual states we investigate how individual states adjusted their sulfur regulation laws in response to acid rain and whether they accounted for differences in marginal abatement costs vulnerability to agricultural damages special industry interests or inter state externalities the welfare gain compared to a uniform reduction in emission rate standards is estimated to be 21 million in 1995 dollars annually

international portfolio nondiversification and exchange rate variability abstract incomplete international portfolio diversification is implied by an equilibrium models of exchange rates with nontraded goods the model can also explain the greater correlation between consumption and income within a country than between consumption across countries nontraded goods make more stringent the elasticity conditions required to explain exchange rate variability resulting from current productivity disturbances though not from disturbances to fiscal policies or the prospective return to investment the model is also consistent with international real interest rate differentials changes over time in the current account and relative wealth across nations and observed time series properties of exchange rates

itqs firm dynamics and wealth distribution does full tradability increase inequality concerns over the re distributive effects of individual transferable quotas itq s have led to restrictions on their tradability we consider a general equilibrium model with firm dynamics to evaluate the redistributive impact of changing the tradability of itqs a change in tradability would happen for example if permits are allowed to be traded as a separate asset from ownership of an active firm if the property right is associated with ownership of an active firm the permit can be leased in each period but it is not possible to exit the industry and keep the right however allowing the permits to be traded as a separate asset has two effects first it leads to a greater concentration of production in the industry second it directly converts a non tradable asset into a tradable one and this is equivalent to giving a lump sum transfer to all firms the first effect implies a concentration in revenues while the second implies a redistribution of wealth we calibrate our model to match the observed increase in revenue inequality in the northeast multispecies groundfish u s fishery we show that although observed revenue inequality measured by the gini coefficient increases by 12 wealth inequality is reduced by 40

explaining the absence of international factor price convergence abstract as capital markets have become integrated factor prices have not converged as expected this paper provides an explanation the key observation is that non specific output risks are borne by capital making international portfolio diversification a dominant strategy capital market integration can elicit many patterns of factor price response under this circumstance factor prices will move in parallel if countries are identical when countries differ factor prices may diverge or even have their relative sizes reversed the integration of capital markets affects welfare through changes in risk and in overall returns to savings welfare need not improve

distributing pollution rights in cap and trade programs are outcomes independent of allocation standard economic theory predicts that if property rights to pollute are clearly established equilibrium outcomes in an efficient emissions permit market will be independent of how the emissions permits are initially distributed this so called independence property has important implications for policy design and implementation past studies document a strong positive correlation between the initial permit allocation and firm level emissions raising concerns that the independence property is failing to hold in real world settings we exploit the random assignment of firms to different permit allocation cycles in southern california s reclaim program in order to test the independence of permit allocation and emissions our results lend empirical support to the independence hypothesis

private property and economic efficiency a study of a common pool resource abstract the british columbia halibut fishery provides a natural experiment of the effects of privatizing the commons using firm level data from the fishery 2 years before private harvesting rights were introduced the year they were implemented and 3 years afterward a stochastic frontier is estimated to test for changes in technical allocative and economic efficiency the study indicates that 1 the short run efficiency gains from privatization may take several years to materialize and can be compromised by restrictions on transferability duration and divisibility of the property right 2 substantial long run gains in efficiency can be jeopardized by preexisting regulations and the bundling of the property right to the capital stock and 3 the gains from privatization are not just in terms of cost efficiency but include important benefits in revenue and product form

the effect of environmental regulation on optimal plant size and factor shares the method for measuring the effects of environmental regulation on the size distribution of industrial plants and the distribution of factor shares described in this paper focuses on the 20 industries with highest per unit pollution abatement costs and the 20 with the lowest costs the study finds that compliance with environmental laws has not only reduced the number of plants in the affected industries but has placed a greater burden on small rather than on large plants besides redistributing within industry market shares environmental regulation has increased the use of capital relative to labor although the disproportionate burden placed on small plants in the high abatement cost industries may have been unintended it is likely that large firms will be less vocal opponents of environmental regulation than are small firms 22 references 12 tables

bureaucratic discretion or congressional control regulatory policymaking by the federal trade commission this paper extends stigler and peltzman s approach to regulation by incorporating a legislature the model yields comparative statics results and hence testable implications the paper then tests between two opposing approaches about regulatory agency behavior the first assumes agencies operate independently of the legislature and hence exercise discretion the second assumes that congress controls agency decisions the recent behavior of the federal trade commission provides the empirical setting substantial evidence is found for the specific predictions of the model including the hypothesis of systematic congressional influence over ftc decisions

the industrial organization of congress or why legislatures like firms are not organized as markets this paper provides a theory of legislative institutions that parallels the theory of the firm and the theory of contractual institutions like market institutions legislative institutions reflect two key components the goals or preferences of individuals here representatives seeking reelection and the relevant transactions costs we present three conclusions first we show how the legislative institutions enforce bargains among legislators second we explain why given the peculiar form of bargaining problems found in legislatures specific forms of nonmarket exchange prove superior to market exchange third our approach shows how the committee system limits the types of coalitions that may form on a particular issue

the problem of the commons still unsettled after 100 years the problem of the commons is more important to our lives and thus more central to economics than a century ago when katharine coman led off the first issue of the american economic review as the us and other economies have grown the carrying capacity of the planet in regard to natural resources and environmental quality has become a greater concern particularly for commonproperty and open access resources the focus of this article is on some important unsettled problems of the commons within the realm of natural resources there are special challenges associated with renewable resources which are frequently characterized by open access an important example is the degradation of openaccess fisheries critical commons problems are also associated with environmental quality a key contribution of economics has been the development of market based approaches to environmental protection these instruments are key to addressing the ultimate commons problem of the twenty first century global climate change jel q15 q21 q22 q25 q54

the advancedness of knowledge in pollution saving technological change with a qualitative application to so2 cap and trade this paper investigates the extent to which advanced knowledge and technology played a role in the so2 compliance process in electric power plants under the us so2 cap and trade program it investigates the hypothesis that advanced knowledge and technology dedicated to pollution abatement played a minor role in that process while relatively unadvanced forms of knowledge and technology played the main role new qualitative evidence in this somewhat well known case is considered interviews with electric power plant r d managers plant level compliance data and the changes undergone by boiler manufacturer coal mining and railroad companies in the supply chain advanced knowledge dedicated to pollution abatement like the type now being emphasised for carbon capture and storage ccs played a minor role while unadvanced knowledge and technology played the main role while there are clearly limits to how far this unadvanced knowledge and technology finding can be generalised to ghg emission control the specific aspects of the so2 case that might be broadly informative of the response to ghg emissions are elaborated in any case the paper shows how innovation in pollution control can be inexpensive and effective without involving very much advanced knowledge and technology for pollution control

efficiency effectiveness and implementation feasibility of energy efficiency rebates the renove plan in spain abstract state sponsored incentive policies frequently include subsidies or rebates for the purchase of more efficient appliances however more research is required into the effects of this tool in isolation a case in point is the so called renove plan in spain first the inefficiency losses dead weight losses associated with energy efficiency rebates must be taken into account such a policy may also encourage the large scale purchasing of energy efficient appliances which may finally result in an increase in electricity consumption rebound effect furthermore although a subsidy is more widely accepted than other tools from social and political viewpoints especially than taxes the fiscal consolidation challenge faced by many countries reduces the scope for environmental policy measures on the expenditure side of the budget and strengthens the need to use taxes to meet the agreed policy objectives this paper shows that the current application of the spanish renove plan with rebates on the dishwasher market for energy efficient appliances generates some welfare losses a rebound effect and a considerable deficit in public budgets the paper examines and assesses the effect of different combinations of taxes and rebates in the case of dishwashers in spain based on their performance in terms of economic efficiency environmental effectiveness and implementation feasibility

world business cycles under fixed and flexible exchange rates this paper studies the behavior of monthly industrial production indices during the recent periods of fixed and flexible exchange rate s the central conclusions are as follows industrial production indices are subject to stochastic trend growth the variances of the monthly growth rates are higher in the flexible exchange rate period than in the fixed exchange rate period and are related to the degree of openness and to national income more open economies tend to experience more variability while richer more diversified economies experience less and output movements have been correlated across countries under both exchange rate regimes and there is evidence of a world business cycle copyright 1988 by ohio state university press

the effect of allowance allocations on cap and trade system performance abstractan implication of the coase theorem is that under certain conditions the market equilibrium in a cap and trade system will be cost effective and independent of the initial allocation of tradable rights that is the overall cost of achieving a given aggregate emission reduction will be minimized and the final allocation of permits will be independent of the initial allocation we call this the independence property this property is important because it means that the government can establish the overall pollution reduction goal for a cap and trade system by setting the cap and leaving it up to the legislature to construct a constituency in support of the program by allocating the allowances to various interests without affecting either the environmental performance of the system or its aggregate social costs we examine the conditions under which the independence property is likely to hold both in theory and in practice

an equilibrium model of exchange rate determination and asset pricing with nontraded goods and imperfect information this paper presents a two country model with maximizing households stochastic production stochastic money growth and perfect capital mobility because of the presence of nontraded goods households in different countries consume different goods analytic solutions are presented for the nominal exchange rate the real exchange rate nominal interest rates and real interest rates it is shown that the model is compatible with some important features of the real world behavior of exchange rates when households are imperfectly informed about the distribution of money growth the exchange rate exhibits patterns of overshooting and is more volatile than the ratio of the money stocks copyright 1987 by university of chicago press

the political economy of market based environmental policy the u s acid rain program the u s acid rain program enacted in 1990 gave valuable tradable sulfur dioxide emissions permits called allowances to electric utilities we examine the political economy of this allocation though no senate or house votes were ever taken hypothetical votes suggest that the actual allocation would have beaten plausible alternatives while rent seeking behavior is apparent statistical analysis of differences between actual and benchmark allocations indicates that the legislative process was more complex than simple models suggest the coalition of states that produced and burned high sulfur coal both failed to block acid rain legislation in 1990 and received fewer allowances than in plausible benchmark allocations some of these states may have received additional allowances to cover 1995 99 emissions by giving up allowances in later years and some major coal producing states seem to have focused on benefits for miners and on sustaining demand for high sulfur coal

trade in nominal assets and net international capital flows abstract nominal assets play a major role in international financial markets while trade in indexed bonds is limited as a result agents are exposed to both price and exchange rate uncertainty nonetheless previous research on net capital flows has assumed the presence of a risk free vehicle to intertemporal asset trade in this paper we develop a general equilibrium intertemporal model with trade limited to nominal bonds and equity we find that exposure to nominal risk dampens net capital flows thus making economies effectively more closed

currency appreciation and deindustrialisation a european perspective during the 1980s policy advisers were successful in promoting the view that movements in the value of the dollar have an inverse relationship to u s international competitiveness this article explains their hypothesis as well as the counterargument that exchange rates positively reflect a country s competitiveness economic policies that boost competitiveness also raise the value of the domestic currency the mirror image of these hypotheses apply to u s trading partners including europe the evidence indicates that european countries were not deindustralized from 1985 to 1990 when the ecu rose in value by more than the dollar had risen in 1980 1985 instead european competitiveness rebounded strongly in the late 1980s reversing the stagnant performance of the early 1980s similarly during the early 1980s when the united states was on one unsupported view deindustralizing european nations generally did not enjoy a surge in their share of output or capital formation instead they suffered from euroscierosis this abstract was borrowed from another version of this item

the demand for environmental quality in driving transitions to low polluting energy sources the purpose of this paper is to understand the long run demand for energy related environmental quality its influence on legislation and on transitions to low polluting energy sources it starts by presenting a simple framework of the relationship between the demand for and supply of environmental quality environmental legislation and energy this forms the structure for presenting a series of episodes in british history where a demand for improvements in energy related environmental quality existed this analysis proposes that markets can drive transitions to low polluting energy sources in specific economic conditions however most probably governments will need to push them and this cannot be expected without strong and sustained demand for environmental improvements yet while demand is a prerequisite it is not enough it must also be spearheaded by strong creative and sustained pressure groups i e powerful lobbying and the weakening of the counter lobby to introduce legislation to enforce it and to avoid it being over turned by future governments

asset markets tariffs and political risk abstract this paper examines a simple model in which exogenous political risk creates uncertainty about tariffs the model predicts a relation between consumption and tariffs that differs radically from that implied by models without asset markets or political risk given the probability distribution of tariffs domestic consumption and utility ex post are lower in states of the world with a domestic tariff and no foreign tariff than with a foreign tariff and no domestic tariff this conclusion emerges despite the fact that the opposite would be obtained in the absence of asset markets so economists should not be surprised if observed relations between consumption and tariffs differ from the predictions of static theory in either time series or cross sections

the impact of tenure on the flow of federal benefits to smsa s the seniority system in congress insures that committee assignments and chairmanships are distributed on the basis of house members tenure this system supposedly means that congressional influence increases with the number of times a member of congress is reelected however research on the impact of tenure on the distribution of federal aid across states has not produced convincing proof that a positive relationship between tenure and aid exists crain and tollison 1977 undertook the first study of the impact of tenure and they concluded that tenure has a positive effect on the share of total federal aid going to states indeed crain and tollison found evidence of diminishing returns to additional years of house service however green and munley 1981 quickly disputed the crain tollison findings suggesting that after adjusting for state population which affects

dynamic behavior of capital accumulation in a cash in advance model abstract this paper analyzes the dynamic behavior of capital accumulation in stockman s cash in advance model if the cash in advance constraint applies only to consumption then money is superneutral along the transition path as well as in the long run alternatively if the cash in advance constraint applies to gross investment as well as consumption then a permanent increase in the rate of monetary growth reduces the steady state capital stock the effect on the speed of adjustment depends on the sign of a certain simple function of the parameters of preferences and technology

money and asset prices in a cash in advance economy an asset pricing model with money introduced via a cash in advance constraint is presented the monetary velocity is variable hence money demand does not obey the trivial quantity equation the effects of disturbances in output and money growth on real balances the price level and interest rates are examined monetary policy has effects on real asset prices the fisher relation and the premium on nominal bonds are discussed the precise role of the timing of information and transactions for properties of price levels and interest rates are clarified

the market for sulfur dioxide emissions the 1990 clean air act amendments initiated the first large scale use of the tradable permit approach to pollution control the theoretical case for this approach rests on the assumption of an efficient market for emission rights the authors empirical analysis shows that the emission rights market created by the 1990 amendments had become reasonably efficient by mid 1994 they also show that the auctions specified in the amendments to jump start trading had become a small part of the overall market finally the authors demonstrate that the strategic bidding behavior discussed in the literature has had no effect on market prices copyright 1998 by american economic association

voluntary compliance with market based environmental policy evidence from the u s acid rain program the u s acid rain program implemented a nationwide market for electric utilities sulfur dioxide so2 emissions and included voluntary compliance possibilities for nonaffected sources i observe significant voluntary participation albeit with small impact on the so2 market mostly from sources with counterfactual emissions below their allowance allocations an ex post analysis suggests that costs from the resulting higher emissions outweigh savings from shifts in emissions reductions from high cost affected sources to low cost nonaffected sources further utilities voluntary participation is well explained by economic variables which provides new evidence of cost effective compliance strategies and low transaction costs

transaction costs and tradeable permits abstract tradeable permit systems are at the center of current interest and activity in market based reforms of environmental policy because these systems can offer significant advantages over conventional approaches to pollution control unfortunately claims made for their relative cost effectiveness have often been exaggerated transaction costs which may be significant in these markets reduce trading levels and increase abatement costs in some cases equilibrium permit allocations and hence aggregate control costs are sensitive to initial permit distributions providing an efficiency justification for politicians typical focus on initial allocations

tradeable carbon permit auctions how and why to auction not grandfather abstract an auction of carbon permits is the best way to achieve domestic carbon caps designed to limit global climate change to minimize administrative costs permits would be required at the level of oil refineries natural gas pipe lines natural gas liquid sellers and coal processing plants to maximize liquidity in secondary markets permits would be fully tradable and bankable the government would conduct quarterly auctions a standard ascending clock auction in which price is gradually raised until there is no excess demand would provide reliable price discovery an auction is preferred to grandfathering giving companies permits based on historical output or emissions because it allows reduced tax distortions provides more flexibility in distribution of costs provides greater incentives for innovation and reduces the need for politically contentious arguments over the allocation of rents

environmental regulation whose self interests are being protected special interest can explain why environmental policy limits economic activity in areas where air quality is above minumum standards locational competition among region helped create a policy that raised factor mobility cost from slower to faster growing regions analysis of votes shows greater support for this policy was received from northern urban constituencies and the greatest opposition came from the south and the west pollution abatement costs per unit of output are higher in areas with higher not lower air quality

exchange rate volatility the role of real shocks and the velocity of money the effects of stochastic output shocks on the behavior of ex change rates and nominal price levels is studied within the context of a two country cash in advance model the analysis of this model in contrast to the existing cash in advance literature demonstrates that exchange rates can be more volatile than price levels even though agents elasticity of substitution between foreign and domestic goods is greater than one half this possibility arises when output shocks are autocorrelated and are due to revisions in expectations that affect the terms of trade and or the velocity of money

monetary growth innovations in a simple cash in advance asset pricing model abstract this paper contributes to the existing literature in the rational expectations cash in advance asset pricing general equilibrium model in two directions first we show that by allowing a variable velocity of circulation an increase in the conditional variance of the money growth process triggers an increase in the demand for money relative to stocks and bonds with a consequent reduction in stock and bond prices which is the opposite of the current result in the literature with constant unitary velocity second we explicitly show how the sequential markets and specific timing of information fits exactly into the notion of irreversibility in the sense that when faced with uncertainty agents might find optimal to delay decisions in order to wait for the arrival of new information

the political economy of pollution markets historical lessons for modern energy and climate planners this article explores some of the central economic and political problems with the use of tradable permits to solve environmental problems drawing from transaction cost economics political economy and market theory it does so by looking at the history of three programs for curbing pollution in the united states the clean air act the leaded gasoline phase out and water permits in wisconsin the article begins by briefly summarizing the history of each of these programs before looking at a host of challenges related to political compromises in program design transaction costs spatial distortions such as geographic sensitivity and wrong way trading of credits temporal distortions such as the episodic nature of pollution and volatility of market prices and market abuses these concerns are raised with an eye for how historical experience may inform the current debate about how to design effective market mechanisms to respond to climate change and other forms of energy related environmental degradation

dynamic regulation design without payments the importance of timing abstract we consider a two period model of optimal regulation of a firm subject to marginal compliance cost shocks the regulator faces an asymmetric information problem the firm knows current compliance costs but the regulator does not both the regulator and the firm are uncertain about future costs in our basic framework the regulator may not offer payments to the firm we show that the regulator can vary the strength of regulation over time to induce the firm to reveal its costs and increase welfare in the optimal mechanism the regulator offers stronger weaker regulation in the first period and weaker stronger regulation in the second period if the firm reports low high compliance costs in the first period low cost firms expect compliance costs to rise in the future and thus prefer weaker regulation in the second period high cost firms expect costs to fall in the future and thus prefer regulation which becomes stricter over time thus the regulator offers the low high cost firms slightly weaker stronger regulation in the second period in exchange for much stronger weaker regulation in the first period thereby timing the regulation if the regulator can make payments then the optimal mechanism to some degree times the regulation as long as a positive marginal cost of funds exists if the marginal cost of funds is high enough then under the optimal mechanism the regulator will not use payments and use our timing mechanism exclusively

capital market response to emission rights returns evidence from the european power sector prior studies on the distributional effects of the european union s emission trading scheme eu ets have so far only relied on supply and demand data empirical evidence from capital markets has been missing we address this gap and measure the ets s economic consequences using the expectations of investors towards the regulatory impact on firm value employing a multifactor model we show that returns on common stock of the largest affected industry power generation are positively correlated with rising prices for emission rights this implies that the market predicts that firms are not only able to pass on their share of the regulatory burden to customers but even achieve windfall profits by overcompensating for the costs

emission taxes and tradable permits a comparison of views on long run efficiency we compare three different views on the long runefficiencies of emission taxes which includethresholds inframarginalexemptions and of tradeable emission permitswhere some permits areinitially free the differences are caused bydifferent assumptions aboutwhether thresholds and free permits should besubsidies given only to firmsthat produce or full property rights treatingtax thresholds as well asfree permits as property rights would departfrom the conventional view but would allow greater flexibility in makingeconomic instruments bothefficient and acceptable such flexibilitycould be very important inachieving efficient control of greenhouse gasemissions

the role of saving and investment in exchange rate determination under alternative monetary mechanisms abstract we argue that the demand for national currencies depends on existing payment arrangements for imports and exports therefore exchange rate movements depend on these arrangement as a result the relationship between exchange rate movements and various macroeconomic aggregates like saving and investment depend on what we call the monetary mechanism these points are explicitly demonstrated by studying two extreme monetary mechanisms one in which all payments are done with the seller s currency and one in which all payments are done with the buyer s currency

anticipated inflation and the capital stock in a cash in advance economy abstract an economy is constructed in which the steady state capital stock is inversely related to the rate of inflation as a result that is directly opposite the usual conclusion

reflections on the double dividend debate we survey the history of carbon taxation the range of market based instruments mbis of environmental control and the state of the double dividend debate in order to suggest directions for future research into mbis returning mbi revenues as lower distortionary taxes rather than as lump sums raises aggregate welfare but we favour mbis which raise little or no revenue for reasons of political acceptability to interest groups at the same time the overall case for any environmental improvement is weaker because of general equilibrium interactions with prior distortionary taxes research seems most necessary on quantifying the efficiency benefits of market control of heterogeneous polluters the benefits of environmental improvement the tax interaction effect and the various information costs of an mbi all on a case by case basis for different pollutants and places

the environment as a factor of production the authors develop a model of environmental resource use in production with an empirical analysis of how electric power companies consume and bank sulfur dioxide pollution permits the model considers emissions fuels and labor as variable inputs with quasi fixed inputs of permits and capital incorporating information from permit markets allows the authors to distinguish between user costs and asset shadow values their findings indicate that firms are holding stocks of pollution permits for reasons other than short term cost savings the results also reveal substantial substitution possibilities between emissions permits stocks and other factors of production the authors speculate that anticipated secondary markets for carbon offset inventories related to the flexibility mechanisms of the kyoto protocol will have similar effects for greenhouse gas emitting firms

evaluating tradable property rights for natural resources the role of strategic entry and exit this paper presents an econometric approach to the evaluation of environmental regulation using tradable property rights existing empirical research on this issue which compares overall industry efficiency before and after the introduction of new regulations conflates two distinct phenomena efficiency changes due to exit of excess capital and changes in the efficiency of individual firms because the regulatory process induces firms of different types to enter and exit the industry at different rates the true efficiency and equity effects of tradable property rights cannot be assessed without correcting for these changes in sample composition this paper examines the impact of regulatory change in the mid atlantic surf clam fishery using an econometric model that separates its effects on industry structure and vessel efficiency the analysis finds that contrary to widely held belief tradable property rights did not disproportionately benefit either large fishing firms or highly integrated firms

optimal design of a phase in emissions trading program abstract this paper studies a phase in emissions trading program with voluntary opt in possibilities for non affected firms and derives optimal permits allocations to affected and opt in firms when the environmental regulator has incomplete information on individual unrestricted emissions and control costs the regulator faces a trade off between production efficiency minimization of control costs and information rent extraction reduction of excess permits allocated to opt in firms the first best equilibrium can be attained if the regulator can freely allocate permits to affected and opt in firms otherwise a second best equilibrium is implemented the latter is sensitive to uncertainty in control costs and benefits

trade in nominal assets monetary policy and price level and exchange rate risk in a previous paper trade in risky assets i have analyzed the pattern of international trade in risky real assets between barter economies relying on the law of comparative advantage and using autarky asset price differences to predict the pattern of asset trade in this paper the analysis is extended to international trade in nominal assets assets with returns paid in currencies between monetary economies the risk chracteristics of real returns on nominal assets depend on price level and exchange rate risk and therefore on monetary policy it is examined how different combinations of monetary policies and exchange rate regimes affect nominal assets return risk characteristics their autarky perices and hence their trade pattern when countries differ with respect to their outputs or their attitudes towards risk when world asset markets are incomplete different monetary policies and exchange rate regimes have dramatic effects on risk characteristics of home and foreign currency bonds and on the trade pattern in these assets as well as on aggregate capital and current accounts

cap and trade taxes and distributional conflict enacting market based environmental regulation such as emissions taxes and cap and trade programs often create rents that are contested by agents in this paper we create a framework that compares social welfare from alternative market based environmental policy instruments under the presence of rent seeking we show that contrary to the commonly held view non revenue raising instruments nrris are in many cases preferable over revenue raising instruments rris we find that the choice of instrument depends on the size of a potential revenue recycling effect and the level of preassigned rents

teams teamwork and absence we argue that firms with interdependent worker productivity team production have a higher cost of absence and as a consequence spend additional resources on monitoring absence as a result firms with team production should have lower absence rates we estimate the determinants of absence for blue collar workers using a sample of german manufacturing establishments workplace teams are used as a proxy for team production the estimates reveal that firms with teams have lower absence rates as do smaller establishments the size effect however is unique to establishments with teams which fits prior theoretical work that has not been previously tested

transitional politics emerging incentive based instruments in environmental regulation abstract this paper proposes a positive theory of environmental instrument choice we study a democratic society that seeks to lower the level of pollution from industrial sources to a pre specified target the target can be implemented by one of three instruments s uniform emission standards p tradeable permits and t emission taxes the conflict of interest between special interests representing polluters and the electorate is resolved by an elected politician we characterize when each of the three policy instruments is chosen in political equilibrium and show that the transition observed in many countries from s to either p or t can be understood as a natural consequence of increasingly ambitious environmental targets

intergenerational effects of a green tax reform for a more sustainable social security system abstract green tax reforms are popular in some circles not only because of their direct effect on reducing pollution but also because their revenue capacity may allow to reduce other more distortionary taxes despite their potential benefits the political implementation of green tax reforms is not straightforward changes in environmental taxes have different intergenerational effects which need to be taken into account when considering their political support among a country s population in this paper we analyze the economic and intergenerational welfare effects of introducing a green tax reform to ameliorate the spanish social security system we consider two types of energy taxes an energy consumption tax and an energy input tax we find that both types of reforms are favored by young individuals but rejected by older generations the number of generations supporting the reform depends crucially on the disutility that individuals derive from pollution suggesting that an increase in environmental awareness may be needed for green tax reforms to be politically viable

savings investment and international capital flows abstract the high correlation between national savings and domestic investment rateshas been interpreted as evidence that capital is not internationally mobile this paper surveys the theory and evidence on the relationship between savings and investment in a sample of 23 oecd countries a positive correlation between savings and investment rates is found in both the short and long runs however a wide variety of models generate such co movements in savings and investment in response to exogenous disturbances even under conditions of complete financial markets thus the savings investment correlation provides little evidence on the question of international capital mobility

tradable deficit permits efficient implementation of the stability pact in the european monetary union tradable deficit permits efficient implementation of the stability pact borrowing from the experience of environmental markets this paper proposes a system of tradable deficit permits as an efficient mechanism for implementing fiscal constraints in the european monetary union having chosen an aggregate target for the union and an initial distribution of permits emu countries could be allowed to trade rights to deficit creation the scheme exploits countries incentives to minimize their costs is transparent and flexible in accommodating idiosyncratic shocks and allows for adjustments in case of europe wide recessions in addition it need not treat all countries identically and can be designed to penalize countries with higher debt to gdp ratios finally the scheme rewards countries for reducing their deficit below the initial allowance lending credibility to the stability pact s goal of a balanced budget in the medium run alessandra casella

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

on the european monetary system the spillover effects of german shocks and disinflation we analyse the disinflationary experience between 1979 93 for two traditionally inflationary countries of the european monetary system france and italy for each country a vector autoregressive model is estimated shocks in the model combine domestic and foreign sources the latter capture the world oil price shocks as well as nominal and real shocks originating in germany under investigation is the hypothesis that shocks originating in germany have a spillover disinflationary effect in france and italy the empirical evidence provides support to the validity of this hypothesis furthermore german shocks account for an important share of the total price variance in france and italy these results indicate that the interaction between countries of the european monetary system has contributed to the success of the disinflationary experiences of the 1980s the evidence sheds therefore some light on potential benefits that may be further realized as countries of the european monetary system move towards

dynamics of a floating exchange rate regime we study the full equilibrium dynamics of a two country world economy with a floating exchange rate traded and nontraded goods and explicit modeling of the use of money the resulting exchange rate equation depends on several details of the economic structure such as the supply structure and propensities to spend on various goods although real exchange rate movements have the usual association with the current account the ordinary exchange rate may appreciate or depreciate when there are deficits on current account even when the quantities of money do not change deviations from purchasing power parity and the fisher equation are shown to be the rule rather than the exception

allocation of co2 emissions permits a general equilibrium analysis of policy instruments what are the effects of different ways of allocating co2 emissions permits under a tradable permit scheme numerical simulations show that using the permit revenue to lower existing taxes implies by far the lowest welfare cost but also a large reduction in employment in energy intensive sectors and substantial stranded costs grandfathering the permits compensates owners for losses on stranded investments but comes at a welfare cost and does not mitigate the adjustment imposed on the economy finally distributing the permits according to market shares reduces the degree of sectoral adjustment but also comes at a high welfare cost

currency preferences purchasing power risks and the determination of exchange rates in an optimizing model most recent research on the theory of exchange rate determination treats the exchange rate as the relative price of two assets domestic money and foreign money the value of an asset depends on the distribution of its return however most of the research has dealt with models in which there is no uncertainty the present paper focuses on questions that cannot be addressed in a world of certainty because in such a world an asset is never risky it investigates how purchasing power risks affect the determination of exchange rates this investigation is pursued in a fairly general optimizing model the present research is related to some recent work in international economics and in financial economics it follows the approach of obstfeld 1981 and stockman 1980 in that it uses an optimizing model and takes into account the role of government transfers in the flow budget constraint of individuals as in calvo and rodriguez 1977 stockman 1980 and others the fact that holdings of foreign monies are useful to domestic individuals is taken into account finally the paper uses techniques developed in papers in the finance literature which build on merton s 1973 asset pricing model and use a concept of equilibrium developed in

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

capital flows investment and exchange rates abstract this paper incorporates international capital flows into a two country monetary general equilibrium model of asset prices with investment and production we calculate theoretical covariances between investment the current account the exchange rate and the terms of trade these covariances depend upon the coefficient of relative risk aversion the magnitude and sign of a country s net international indebtedness other properties of tastes and technologies and the stochastic processes on disturbances to productivity and monetary growth rates international capital flows arise from changes in world wealth and its relative composition in foreign and domestic assets
