environmental regulation and u s economic growth in this article we quantify the costs of pollution controls by reporting the results of simulations of the growth of the u s economy with and without regulation for this purpose we have constructed a detailed model of the economy that includes the determinants of long term growth we have also analyzed the interaction between industries in order to capture the full repercussions of environmental regulations however we have not attempted to assess the benefits resulting from a cleaner environment we find that pollution abatement has emerged as a major claimant on the resources of the u s economy the cost of emission controls is more than 10 of the total cost of government purchases of goods and services

heterogeneous wage effects of apprenticeship training the relatively small average wage effects of employer and occupation changes after apprenticeship training mask large differences between occupation groups and apprentices with different schooling backgrounds people who change employer and occupation within industrial occupations enjoy large wage advantages whereas apprentices in commerce and trading occupations as well as in construction and crafts occupations face wage losses from an occupation change the differences between the firms that provide the apprenticeship training are found to be small or insignificant in this paper we reconcile the differences between previous findings by comparing and replicating the empirical estimation strategies used this demonstrates that selectivity in occupations and changes unobserved heterogeneity between occupations and sample selection do matter

wages experience and seniority in this paper we study the sources of wage growth we identify the contribution to such growth of general sector specific and firm specific human capital our results are interpretable within the context of a model where the returns to human capital may be heterogeneous and where firms may offer different combinations of entry level wages and firm specific human capital development we allow for the possibility that wages are match specific and that workers move jobs as a result of identifying a better match to estimate the average returns to experience sector tenure and firm specific tenure within this context we develop an identification strategy which relies on the use of firm closures our data source is a new and unique administrative data set for germany that includes complete work histories as well as individual characteristics we find positive returns to experience and firm tenure for skilled workers the returns to experience for unskilled workers are small and insignificant after 2 years of experience their returns to sector tenure are also zero however their returns to firm tenure are substantial in this paper we study the growth of wages of young workers in germany knowing the extent and reasons for individual wage growth over the life cycle is important for a number of areas in economics just to mention two examples first it is a key element to understanding and designing active labour market programmes many such programmes offer temporary and often subsidized work opportunities examples are the new deal in the u k and the swedish programmes as well as a number of programmes in germany these programmes are based on the assumption that general skills are sufficiently enhanced while working so as to render the workers employable without a wage subsidy thus the success of these programmes depends on how skills improve on the job for the target population and whether this skill enhancement is transferable across jobs second it is a key to understanding the benefits and costs of job mobility this in turn matters for a number of policy issues including the design of pension policies relating for example to final salary schemes as a result of this widespread interest a large body of empirical research has focused on obtaining estimates for the returns of experience and seniority 1 our study uses a new and unique administrative data set with a number of features that are important for our analysis and allow us to avoid many problems encountered in earlier work in this field in our model wages grow due to learning by doing which may be heterogeneous across individuals moreover since firms offer different career profiles and because we allow for match specific effects on wages investments take the form of searching for the firm with the most desirable learning by doing characteristics career structure 2

discussion of voluntary disclosure choice and earnings information transfer pownall and waymire s paper prompted a general discussion of information transfer research particularly its motivation and methodology this summary begins with a brief introduction to information transfer research it then considers motivation and methodology since the discussion related both to pownall and waymire s research specifically and to information transfer research generally these discussion comments extend to both as well

the school to work transition a cross national perspective school to work patterns and issues are discussed for seven economies france germany japan the netherlands sweden the united kingdom and the united states the emphasis is placed on differences across countries in the current labor market position of young people and recent trends therein along with the institutions that regulate youth education training and employment the power of public policies including labor market deregulation labor market programs vocationalization of education and apprenticeship to improve youth outcomes is discussed drawing on national evaluation literatures evidence of extensive policy failure points up the need to develop nationally appropriate institutions to improve school to work transitions

uniform compliance costs for mineral commodities who gains and who loses changes in energy and nonfuelmineral production consumption and net export revenue that result from environmental protection are estimated by income class and geographic region unlike previous assessments of unilateral adoption of standards i assume that all producers incur equal cleanup costs adjustment is therefore accomplished through changes in prices and quantities rather than altered trade patterns the estimated magnitude of worldwide changes is not large moreover many poor countries are forecast to benefit since their terms of trade improve however the problem of obtaining foreign exchange for investment remains a financing scheme that divorces efficiency from equity is suggested

the effect of clean water regulation on profitability testing the porter hypothesis previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability this study provides empirical evidence on this debated effect by testing the strong version of the porter hypothesis we employ panel data analysis to examine the effect of water regulation as measured by permitted wastewater discharge limits on the profitability of publicly held firms operating within the chemical manufacturing industries we find that tighter water regulation meaningfully lowers profitability by reinterpreting profitability in terms of sales and costs the results demonstrate that tighter water regulation increases costs conditioned on a given level of sales

information processing and jury decisionmaking abstract we develop a model to explore the information processing function that jury deliberation and its analogues perform the central question we ask is how much better could a jury possibly perform if it optimally used the collective information available to it than if it decides cases by a simple majority vote before any deliberation or information sharing occurs it is shown how the answer depends on a number of considerations including the correlation among jurors observations the jurors assessments of the relative importance of type i and type ii errors compared with society s assessment of those errors and differences in jurors abilities

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

returns to apprenticeship training in austria evidence from failed firms in the german speaking countries little is known about the payoffs to apprenticeship training for the participants ols estimates suggest that the returns are similar to those of other types of schooling however there is considerable heterogeneity in the quality of apprenticeships offered and institutional descriptions suggest that there might be an important element of selection in who obtains an apprenticeship and what type in order to overcome the resulting ability bias we estimate returns to apprenticeship training for apprentices in small austrian firms which cease to operate when a firm fails current apprentices cannot complete their training in this firm since apprentices will be at different stages in their apprenticeship at that time the failure of a firm will manipulate the length of the apprenticeship period completed for some apprentices the time to firm failure can therefore serve as an instrument for the length of the apprenticeship completed both at the original firm and at other firms we find instrumental variables returns which are similar or larger than the ols returns in our sample indicating relatively little selection

market based systems for reducing chemical use in agriculture in the united states this study uses a computable general equilibrium cge model of the u s economy to estimate the economic effects of agricultural fertilizer and pesticide input reductions on individual farm sectors and on the economy as a whole the costs of reducing agricultural chemicals using a market based approach and a command and control approach are compared the real cost to society of restrictng fertilizer and pesticide use by 20 percent across all uses is estimated to be 2 3 billion a market based approach that would provide incentives to reduce chemical use in the most cost efficient manner would be about 10 percent less costly

environmental regulation by private contest abstract it is widely expected that the recent trend in the us eu and elsewhere towards an increased role for private agents and agencies in the formulation and enforcement of environmental regulation will continue if environmental regulation is to be privatised in this way it is natural to ask how far the activities of environmental groups on whose shoulders much of the responsibility for defending the environment is likely to fall should be subsidised or taxed in this paper we identify the trade offs involved and characterise the optimal subsidy tax the analysis is argued to have significant implications for how governments should think about the way in which fiscal law treats environmental ngo s

firm specific human capital a skill weights approach the theory of human capital is agnostic on what constitutes firm specific skills the theory specifies that specific skills contribute to productivity only at the current firm a broader approach lets all skills be general but firms use them with different weights attached for example computer programming economics and accounting are general skills but there may be only one firm that wants workers trained in all three one implication is that wage profiles and the split of human capital costs depend on thickness of the market another is that firms pay for what appears to be general training

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

setting the stakes in environmental contests abstract firms are frequently in conflict with environmental groups over planning and other decisions standard contest models assume that stakes are exogenously defined which is inappropriate in settings such as application for building permission in which one player also acts as proposer assuming that proposers foresee environmental opposition they will adjust their proposals strategically by introducing an additional stage to the lobbying game the full impact of the dispute process can be reckoned the structure of the game the order in which the players move is shown to have a significant impact on social welfare and may warrant intervention among other things there may be social gains to forcing the developer to move last in planning disputes

valuation by conflict abstract nonmarket valuation remains a central issue in ecological and environmental economics this paper examines the properties of an ex post revealed preference approach to value nonmarket goods valuation through observed effort expended in an environmental conflict we consider the strategic interaction between players in a conflict address the implied nash equilibrium and report a benchmark 4x rule as an ex post valuation estimate for a symmetric player conflict we then illustrate the degree of bias that exists once one allows for asymmetries in delegation ability and valuation the benchmark tends to overestimate value if a firm hires a powerful delegate who receives a large contingency fee

energy policy and public opinion manipulation of environmental threats by vested interests in the uk and west germany abstract the thesis that public concern about the environment is in part engineered in order to make public and corporate policy socially acceptable is put forward for discussion the thesis is abstracted from the policy history of acid rain abatement in west germany and nuclear waste disposal in the uk if public opinion is not a determining factor of energy policy the opposite is often alleged especially in west germany but a dependent variable important conclusions would follow about the role of government in raising environmental awareness the credibility of expert advice and the significance of decision making structures and processes in order to protect policy credibility expert advice would have to come from sources perceived to be independent of both corporate and government interests the focus of the energy policy debate would have to move in the uk from content to process

natural versus manufactured capital win lose or win win a case study of the finnish pulp and paper industry abstract the effect of investments on environmental variables has been discussed through the win win rhetoric specifically in micro level analysis on the macro level the win win rhetoric has been replaced by the arguments for and against the substitutability of natural and manufactured capital here these two concepts belonging to different levels of analysis are linked by looking at the environmental and economic effects of chosen investment strategies in a traditionally capital intensive industry over time the paper shows that rather than generalise the existence of win win situations or the substitutability of capital these positions are determined by purely situational factors as a result in the assessment of substitutability the specific operating context of the industry needs to be taken into account this implies also that environmental policy needs to be designed to be adaptive and responsive to those situational factors to create beneficial outcomes for the economy and for the environment

sectoral and macroeconomic impacts of the large combustion plants in poland a general equilibrium analysis abstract this paper analyses the final incidence of direct costs of implementation of the eu directive on so 2 and no x emission limits for large combustion plants in poland first we simulate a model from a power sector perspective where compliance with the directive appears to be associated only with direct costs second a more realistic market wide perspective is modeled where abatement costs borne by the power sector become the revenues of the sectors supplying abatement technologies and services simulations indicate that if environmental benefits of implementation are unaccounted for the directive would seem to cause a deadweight loss in the economy the overall impact however is likely to be less negative than what the interest groups claim

the role of policy in energy transitions lessons from the energy liberalisation era the aim of this paper is to discuss the period of energy privatisation and liberalisation which began in the 1980s within its wider historical context the key issues are what has been learned from this recent period and how significant is it in the light of an energy transition to low carbon energy system by 2050 energy liberalisation has led to positive and globally widespread but modest efficiency gains but a lack of clearly visible direct benefits to households in many countries it has significantly improved the governance of monopoly utilities via independent regulators the prospects for competition and innovation and the quality of policy instruments for environmental emissions control through the emergence of trading mechanisms we conclude that it is not liberalisation per se that will determine the movement towards a low carbon energy transition but the willingness of societies to bear the cost which will be significant no matter what the extent of liberalisation

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

dynamic rent seeking abstract a dynamic model of the political process is presented under conditions of uncertainty as in an earlier model by becker several interest groups vie for political influence exerted in the form of taxes and subsidies some results of the static single interest group theory of rent seeking are given slightly modified interpretations among other things it is shown that a group s rent seeking activity is negatively related to the rate of growth of national income to the group s relative position in the income distribution and to measures of how deserving it is the importance of voting is modelled explicitly it is also found that policies tend to be adopted which minimize the deadweight welfare losses from rent seeking

the substantial bias from ignoring general equilibrium effects in estimating excess burden and a practical solution we show that under typical conditions the simple excess burden triangle formula substantially underestimates the excess burden of commodity taxes in some cases by a factor of 10 or more this formula performs poorly because it ignores general equilibrium interactions most important interactions between the taxed commodity and the labor market many prior studies have shown that general equilibrium interactions affect excess burden but have not appreciated the bias associated with ignoring these interactions or the quantitative importance of this bias we derive an implementable alternative to the simple formula this alternative formula captures interactions that the simple formula omits as a result it is both unbiased and usually more accurate

german works councils and the anatomy of wages using matched employer employee data from the german liab for 2001 the authors found that german works councils are in general associated with higher earnings even after accounting for establishm

why do firms train theory and evidence this paper offers a theory of training whereby workers do not pay for the general training they receive the superior information of the current employer regarding its employees abilities relative to other firms creates ex post monopsony power and encourages this employer to provide and pay for training even if these skills are general the model can lead to multiple equlibria in one equilibrium quits are endogenously high and as a result employers have limited monopsony power and provide little training while in another equilibrium quits are low and training is high using microdata on german apprentices we show that the predictions of our model receive some support from the data

the control of co2 emissions and its economic impact an age model for a german state since it is believed that co2 is responsible for 55 of the greenhouse effect a co2 levy is now under consideration in several countries for an assessment of the macroeconomic implications of an integrated energy and environmental policy we employ an applied general equilibrium model age since all sectors of an economy and all private households contribute to co2 emission our model is a temporary equilibrium model with capacity extension under adjustment costs and with abatement activities for so2 and nox emissions

positive and negative information transfers from management forecasts we examine positive and negative information transfers associated with management earnings and revenue forecasts positive information transfers are due to industry commonalities whereas negative information transfers are caused by competitive shifts we argue that positive and negative intra industry information transfers offset each other and lead to an overall finding of no information transfers even though they exist we also conjecture that the type of information transfers from the same management forecast can be positive or negative based on the characteristics of the information receiver we hypothesize positive information transfers to nonrival firms and negative information transfers to rivals consistent with our prediction we find negative positive information transfers between forecasting firms and nonforecasting rival nonrival firms in the same industry through analyses using competitors identified by hoover s and 10 k reports we show more general evidence of negative information transfers to rival firms

willingness to pay for ozone control inferences from the demand for medical care abstract the paper applies a discrete choice version of the household production approach to the valuation of nonmarket goods willingness to pay for tropospheric ozone control is estimated using medical care demand under assumptions of input necessity and weak complementarity in example calculations individuals living in high ozone areas are willing to pay over 170 annually for an environment in which ozone concentrations never exceed 12 pphm willingness to pay figures are two to four times larger than medical expense savings caused by the same ozone reductions estimates obtained are compared with results of previous studies and proposed ozone control measures are discussed

estimating the costs of environmental protection in brazil abstract in this paper an effort is made to estimate the amounts of money the government of the state of sao paulo brazil must transfer to counties in which environmentally protected areas of any sort have been established by the state a methodology to estimate these transfers is proposed based on the potential loss of production in the protected areas and the corresponding amounts are calculated the results indicate that protecting 7 68 of the state s territory will cause a maximum decrease in its gdp of 0 05 the estimation of monetary values for environmental costs is of interest because it provides a basis for judgement among different environmental protection alternatives and between these and other investment projects

in the right place at the wrong time the role of firms and luck in young workers careers we examine administrative data on young german workers and their employers to study the long term effects of an early career job loss to account for nonrandom sorting of workers into firms with different turnover rates and for selective job mobility we use changes over time in firm and age specific labor demand as an instrument for displacement we find that wage losses of young job losers are initially 15 percent but drop to zero within five years only workers leaving very large establishments suffer persistent losses a comparison of estimators implies that initial sorting negative selection and voluntary job mobility biases ordinary least squares estimates toward finding permanent negative effects of early displacements

conflict and rent seeking success functions ratio vs difference models of relative success the rent seeking competitions studied by economists fall within a much broader category of conflict interactions that also includes military combats election campaigns industrial disputes lawsuits and sibling rivalries in the rent seeking literature each party s success pi which can be interpreted either as the probability of victory or as the proportion of the prize won has usually been taken to be a function of the ratio of the respective resource commitments alternatively however pi may instead be a function of the difference between the parties commitments to the contest the contest success function csf for the difference from is a logistic curve in which as is consistent with military experience increasing returns apply up to an inflection point at equal resource commitments a crucial flaw of the traditional ratio model is that neither onesided submission nor two sided peace between the parties can ever occur as a cournot equilibrium in contrast both of these outcomes are entirely consistent with a model in which success is a function of the difference between the parties resource commitments

a model of benchmarking regulation revisiting the efficiency of environmental standards the conventional economic argument favors the use of market based instruments over command and control regulation this viewpoint however is often limited in the description and characteristics of the latter namely environmental standards are often portrayed as lacking structured abatement incentives yet contemporary forms of command and control regulation such as standards stipulated via benchmarking have the potential to be efficient we provide a first formal analysis of environmental standards based on performance benchmarks we show that under specific conditions standards can provide efficient incentives to improve environmental performance

environmental policy under imperfect information incentives and moral hazard abstract when net emissions of individual polluters cannot be efficiently monitored then emissions charges controls on emissions levels or subsidies for emissions reduction are not effective as environmental policy instruments this paper proposes instruments that can be applied in such limited information situations these instruments take the form of contracts between a pollution control agency and individual polluters the contracts include a combination of fines and subsidies that induces dischargers to follow optimal environmental policies in the absence of individual monitoring

measuring the environmental consequences of trade policy a nonmarket cge analysis the newly approved gatt trade agreement is likely to focus greater attention on the conflicts between the proliferation of diverse national policies toward environmental quality and the need to maintain competitiveness in world markets virtually all policy evaluations of this conflict have been limited by a significant misspecification in existing models none of the available computable general equilibrium cge models for international trading patterns consistently reflect the effects of environmental resources on consumers preferences the purpose of this paper is to report the first generation of a composite nonmarket and cge model nm cge for the european community the united states japan and a single region for the rest of the world the model incorporates the morbidity and mortality effects of particulates sulfur oxides and nitrogen oxides it uses existing nonmarket valuation estimates freeman with a specification for consumer preferences that allows changes in atmospheric emissions to diffuse in different amounts to

estimates of the costs of kyoto marrakesh versus the mckibbin wilcoxen blueprint in this paper we update our earlier estimates of the cost of the kyoto protocol using the g cubed model taking into account the new sink allowances from recent negotiations as well as allowing for multiple gases and new land clearing estimates we then compare the protocol to an alternative policy outlined in mckibbin et al brookings policy brief no 17 june the brookings institution washington 1997 climate change policy after kyoto a blueprint for a realistic approach the brookings institution washington 2002a j econom perspect 16 2 2002b 107 that does not impose rigid emissions targets we focus particular attention on the sensitivity of compliance costs under each policy to unexpected changes in future economic conditions to illustrate the issue we evaluate the policies under two plausible alternative assumptions about a single aspect of the future world economy the rate of productivity growth in russia we find that moderate growth in russia would raise the cost of the kyoto protocol by as much as 50 percent but would have little effect on the cost of the alternative policy we conclude that the kyoto protocol is inherently unstable because unexpected future events could raise compliance costs substantially and place enormous pressure on governments to abrogate the agreement the alternative policy would be far more stable because it does not subject future governments to adverse shocks in compliance costs

corporate lobbying regulatory conduct and the porter hypothesis michael porter the influential harvard management guru has promoted the idea that compliance with stricter environmental regulations can afford secondary benefits to firms through improved product design innovation corporate morale and in other ways once these secondary benefits are factored the net cost of compliance is argued to be lower than conventionally thought and may even be negative whilst environmental economists have rejected the porter hypothesis as being based on excessively optimistic expectations of the likely size of such secondary benefits the underlying ideas do enjoy significant credence in the business community in the context of a lobbying model of regulatory policy making we argue that the epa should change the way it conducts regulatory policy to take account of porter s views even if it knows those views to be misguided the model serves to illustrate the more general point that fashions in management thinking can be expected to impact the optimal conduct of regulatory policy

human capital specificity evidence from the dictionary of occupational titles and displaced worker surveys 1984 2000 measures of four basic skills constructed from the dictionary of occupational titles are used to examine the source of human capital specificity the measures are used to characterize the skill portfolio of each job and to construct distance measures between jobs wage losses in the displaced worker surveys are shown to be more closely associated with switching skill portfolios than switching industry or occupation code per se these switches represent large decreases in the skill portfolio in the postdisplacement job the recent evidence for industry specific capital is reexamined the results suggest a difference between fluid and crystallized skills

environmental groups in monopolistic markets we examine a market in which a monopolistic firm supplies a good the production of the good causes damage to the environment consumers are heterogeneous with respect to their disutility of the environmental damage an environmental group can enter the market and set up a campaign in order to influence consumers preferences we characterize the equilibrium of the resulting entry deterrence game and investigate its properties it turns out that the aggregated environmental damage is lowest if the firm is able to deter entry of the environmental group and moreover the fixed entry cost of the environmental group is small enough

when green isn t mean economic theory and the heuristics of the impact of environmental regulations on competitiveness and opportunity cost abstract the conventional neoclassical economic wisdom argues that the opportunity costs of environmental regulations are high with negative implications for costs and profits and by implication for growth and per capita gross domestic product gdp the minority view that environmental controls induce cost offsets that minimise such opportunity costs is marginalised by the conventional wisdom which assumes that economic agents are x efficient in production a behavioral model of the firm is presented in this paper whereby x inefficiency in production prevails even in a world of perfect product market competition that is dominated by rational economic agents in this model environmental regulations affect both the level of x efficiency and the extent of technological change and greener firms can be cost competitive and profitable however private economic agents cannot be expected to adopt green economic policy independent of regulations since in this model there need not be any economic advantage accruing to the affected firms in becoming greener

intraindustry information transfers associated with management forecasts of earnings this study documents information transfers associated with the sign and magnitude of the changes in earnings expectations conveyed by management forecasts that is the management forecast of one firm discloser generates unexpected price reactions for firms nondisclosers similar to the forecaster the results are consistent with information transfers documented for releases of actual earnings foster 1981 and sales announcements olsen and dietrich 1985 1 these results build on prior management forecast research that has documented a link between the sign and magnitude of the changes in earnings expectations conveyed by management forecasts and the unexpected share returns price reactions of forecasting firms ajinkya and

agreeing on efficient emissions reduction we propose a simple contest based mechanism providing incentives to reduce harmful emissions to their efficient level without infringing upon productive efficiency participation in the most stylized form of the scheme is voluntary and individually rational all rules are mutually agreeable and are unanimously adopted if proposed the scheme balances its budget and requires no principal in a perhaps more realistic stochastic output version which could potentially inform policy decisions we show that the transfers required by the efficient mechanism create a mutual insurance motive that can serve as an effective rationale for the gradual formation of international environmental agreements

banning the bulb institutional evolution and the phased ban of incandescent lighting in germany much academic attention has been directed at analysing energy efficiency investments through the lens of behavioural failure these studies have challenged the neoclassical framing of regulation which emphasises the efficiency benefits of price based policy underpinned by the notion of rational individual self mastery the increasing use of a regulatory ban on electric lamps in many countries is one of the most recent and high profile flash points in this dialectic of freedom versus the state in the public policy discourse this paper interrogates this debate through a study of electric lamp diffusion in germany it is argued that neoclassical theory and equilibrium analysis is inadequate as a tool for policy analysis as it takes the formation of market institutions such as existing regulations for granted further still it may be prone to encourage idealistic debates around such grand narratives which may in practice simply serve those who benefit most from the status quo instead we argue for an evolutionary approach which we suggest offers a more pragmatic framing tool which focuses on the formation of market institutions in light of shifting social norms and political goals in our case progress towards energy efficiency and environmental goals

economies of scope and scale in green advocacy environmental advocacy is a large and growing activity whilst a number of economists have analysed the advocacy process no systematic attempt has been made to understand the factors influencing the organisation of the sector we explore the relationship between economies of scale and scope in advocacy under the most popular specification of a tullock type contest economies of scope arise when and only when the scale of that activity is sufficiently large the incentives for merger are socially efficient implying no need for policy intervention

private enforcement of federal environmental law while the role of nongovernmental organizations in environmental policy is growing rapidly our analytical understanding of the causes and consequences of this emerging role has not kept pace in the 1970s congress authorized private organizations to seek injunctions and in some cases penalties against firms violating the terms of their environmental operating permits the economic models in this paper show how the varying remedies limitations and reimbursement procedures can affect both the level and patterns of litigation activity as well as the compliance consequences a database containing information on 1 205 cases is used to infuse empirical content into the analysis

private vs public regulation political economy of the international environment minimum standards set by a world environmental organization weo and ngo labelling are promoted as alternative approaches to international environmental protection we explore the potential inter play between these two approaches when the weo is subject to pressure from producers we find that if weo and ngo schemes are mutually exclusive then the existence of an ngo alternative increases industry resistance to weo proposals and this may reduce welfare if however the schemes are run in parallel existence of the ngo lessens producer opposition to weo activities this allows the weo to be bolder in its proposals which is good for welfare

training systems and labor mobility a comparison between germany and sweden the mobility effect of general and specific training is a key issue in the debate on the design of educational systems using data from two retrospective life history surveys we compare general school based vocational training and specific apprenticeship training with regard to inter firm inter occupational and inter industrial mobility the results show that workers with school based degrees display greater occupational mobility while no difference in firm and industrial mobility can be discerned this suggests that apprenticeships do not eliminate job search at labor market entry that they reduce occupational mobility and that responsiveness to structural change is similar under both training systems

occupational specificity of human capital we find that returns to occupational tenure are substantial everything else being constant 5 years of occupational tenure are associated with an increase in wages of 12 20 moreover when occupational experience is taken into account tenure with an industry or employer has relatively little importance in accounting for the wage one receives this finding is consistent with human capital being occupation specific

intra industry information transfers associated with earnings releases abstract the impact that a firm s earnings releases have on the stock prices of other firms in its industry is examined for an identifiable sub set of firms the results are consistent with a significant information transfer occurring between the earnings release firm and the other firms in its industry this subset is identified by examining the impact of the release on the stock price of the announcing firm the magnitude of this impact is more significant for a sample of firms which have a larger percentage of their revenues in the same line of business as the earnings release firm vis a vis a sample with a lower percentage of their revenues from the same line of business alternative interpretations of the empirical results are also discussed the research findings have implications for information content and market efficiency research and for research on policy issues associated with disclosure regulation

effort levels in a cournot nash contest with asymmetric information abstract many contests exist where one player does not know his opponent s value of a fixed prize e g unobservable non market preferences for preservation this paper explores how changes in the nature of a one sided information asymmetry affect effort levels in a cournot nash contest the results indicate that the uninformed player s effort is an uncertain input such that his effort is inversely related to risk this reduces his average odds of success comparative static results are driven by the perceived odds of success and risk for the uninformed player and the actual odds of success for the informed player

intra industry information releases a recursive systems approach abstract this paper investigates the extent of intra industry information transfers associated with the half yearly earnings announcements of a sample of australian firms the omitted factor interpretation of foster s 1981 results is examined using a recursive systems specification of the return generating process to model extra market return covariation in cross section although some aspects of the results do appear sensitive to the alternative methodologies the overall conclusion is consistent with foster 1981 and supports the existence of intra industry information transfers associated with firms earnings releases

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

an economic analysis of household waste management abstract this paper provides a comprehensive model of household waste management policy incorporating the possibility of waste reduction effort by the firm and the household and of illegal waste disposal by the household when household waste reduction effort is insignificant the first best optimum can be achieved using various combinations of environmental tax on the firm and waste collection charge on the household however when household waste reduction effort is significant the first best optimum is not achievable and explicit monitoring of illegal waste disposal is needed rendering a simple pigouvian tax sub optimal this paper solves for the second best optimal policy and provides some comparative statics of the optimal policy

the role of investment in environmental lobbying contests this paper establishes that a lobbying stage following investment decisions regarding abatement technology may imply a positive strategic effect of investment pointing to relatively more investment in pollution abatement technologies than without lobbying the intuition is that polluting firms may choose to implement more advanced abatement technology as a credible commitment device in order to lower the investment of environmentalists in the lobbying contest that will ultimately determine whether or not an emissions tax is introduced

environmental regulation and environmental productivity the case of china abstract constrained by the dual mission of supporting industrial growth and reducing emissions china s traditional emission reduction oriented environmental policies unavoidably face a dilemma this study adopts the gml index to calculate china s industrial productivity by considering environmental factors in addition based on the assumption of industry heterogeneity the author examines the non linear relationship between china s environmental regulation and environmental productivity and calculated the optimal regulation environment for industries according to this study when impact of undesirable outputs pollutant emissions is considered environmental regulation and environmental productivity are positively correlated which to some degree validates the porter hypothesis at present environmental regulation has significant positive effects on clean production industries but shows a lag effect on pollution intensive industries the degree of environmental regulation and environmental productivity show an inverted u shaped relation and display three thresholds it should be noted however that the relationship between regulation and productivity may vary across industries these findings have clear policy implications rather than continually increasing the level of environmental regulation the government should establish standards for individual industries that emphasize flexibility
