do labor market policies have displacement effects evidence from a clustered randomized experiment this article reports the results from a randomized experiment designed to evaluate the direct and indirect displacement impacts of job placement assistance on the labor market outcomes of young educated job seekers in france we use a two step design in the first step the proportions of job seekers to be assigned to treatment 0 25 50 75 or 100 were randomly drawn for each of the 235 labor markets e g cities participating in the experiment then in each labor market eligible job seekers were randomly assigned to the treatment following this proportion after eight months eligible unemployed youths who were assigned to the program were significantly more likely to have found a stable job than those who were not but these gains are transitory and they appear to have come partly at the expense of eligible workers who did not benefit from the program particularly in labor markets where they compete mainly with other educated workers and in weak labor markets overall the program seems to have had very little net benefits

implicit co2 prices of fossil fuel use in switzerland abstract this study aims to assess the efficiency of the fossil fuel taxation scheme currently in effect in switzerland to this end the concept of implicit co2 prices is introduced based on which prices for different fossil fuel uses are derived implicit co2 prices are defined as the difference between actual prices paid by consumers and efficient domestic fuel prices efficient domestic fuel prices in turn consist of private production costs a uniform value added tax and only local external costs not including external costs due to co2 emissions and global climate change the resulting prices differ substantially which suggests that there is considerable cost saving potential in reducing co2 emissions in switzerland for passenger cars and air traffic the implicit prices are negative for these uses higher fuel charges would therefore be beneficial from a purely domestic perspective i e without considering the negative repercussions of global warming

community based tradable permits for localized pollution this paper considers the assignment of tradable permits representing property rights of an environmental good to community members who are harmed by pollution generated by firms these community members can in turn sell permits to polluters according to their personal preferences for a special case with a sole household market transactions between the household and polluters achieve an efficient pollution level however for a group of households the decentralized market solution fails to yield social efficiency because of competitive consumption of the environmental goods we design a revenue sharing mechanism akin to unitization under which market transactions also achieve efficient resource allocation importantly in some cases efficiency can be achieved even when regulators are ignorant of the private valuation of the environmental good

internalizing neighborhood externalities the effect of subdivision size and zoning on residential lot prices abstract though land development regulations potentially control neighborhood externalities the developer of a residential subdivision contributes to that control by developing a larger parcel of land this paper reports estimates of the effect of parcel size on the sale price of developed building lots the results indicate that adding an acre to the median development increases lot prices by about 3 amenities appear to be income normal and the return to parcel size is greater in unincorporated areas perhaps due to less intensive governmental control over externalities

effluent regulation and long run optimality a regulator faced with free entry of firms is concerned not only with the implications of public policy for the discharges from a representative firm but also with the total pollution observed at the long run market equilibrium the regulator must take into account not only the effects of regulations upon the net marginal returns of the firm but must also consider the total profit of the firm and incentives for entry and exit this paper shows that effluent charges and tradeable effluent permits lead to long run optimality with entry of small firms the difference between firm payments and environmental damages is interpreted as the rent accruing to the environmental resource this result applies only to the competitive case with small polluters the analysis presented here allows a comparison and clarification of the literature on small and large polluters in a multi input framework with social damages dependent upon total effluents effluent charges are shown here to result in socially optimal entry confirming an assertion of baumol and oates 2 p 179 fn 161 and the important result of schulze and d arge 15 by taking average as well as marginal damages into account the effluent charge results in optimal firm scale levels and the correct input mix at the free entry market equilibrium the firm subject to an effluent tax will operate above or below the private minimum efficient scale depending upon whether average external costs exceed or are less than marginal external costs since public policy to reduce effluents is often directed at reducing the effluentgenerating activity some policy recommendations include a tax on the final output of the polluting firm in some theoretical analyses a relation between the output of the firm and the effluent level is identified and a pigouvian output tax is applied this approach should not be followed by policymakers since an output tax does not provide firms with the correct incentives for either input substitution or market entry it is shown that while a lump sum transfer is needed to provide correct entry incentives when a pigouvian output tax is applied no such transfer is needed if the tax is correctly applied to effluents contrary to 5 even if optimal firm scale and i thank the referees for helpful suggestions the support of the national science foundation under grant ses 82 19121 is gratefully acknowledged any errors are my responsibility 103

avoiding an ecological regime shift is sound economic policy we extend the shallow lake model by adding the capital stock of an industry a government can mitigate the effects of pollution arising from industrial activities by imposing the requirement to abate emissions within this framework two scenarios are examined in the social optimal benchmark the social planner optimally allocates investment in the competitive equilibrium market forces determine the investment in capital but the government can still abate emissions we find that irreversible environmental regime shifts are avoided in the competitive equilibrium by means of a static level of abatement when it is socially optimal to do so

financing for development editors introduction in this double issue of the oxford review of economic policy we publish a set of papers concerned with the mobilization of domestic and foreign capital in support of the united nations sustainable development goals that were launched in september 2015 the papers were originally presented at a conference on financing for development organized by the international monetary fund and the centre for finance and development at the graduate institute in geneva in april 2015

designing economic instruments for the environment in a decentralized fiscal system designing economic instruments for the environment when external effects are important markets will be inefficient and economists have considered several broad classes of economic instruments to correct these inefficiencies however the standard economic analysis has tended to neglect important distinctions and interactions between the geographic scope of pollutants the enforcement authority of various levels of government and the fiscal responsibilities of the levels of government for example externalities generated in a particular local area may be confined to the local area or may spill over to other jurisdictions also local governments may be well informed about how best to regulate or enforce pollution control within their jurisdiction but they may not consider the effects of their actions on other jurisdictions finally the existence of locally generated waste emissions affects the appropriate assignment of both expenditure and tax responsibilities among levels of government the standard analysis therefore focuses mainly upon an aggregate or national perspective it typically ignores the possibility that the externality may be created and addressed by local governments and it does not consider the implications of decentralization for the design of economic instruments targeted at environmental problems this paper examines the implications of decentralization for the design of corrective policies that is how does one design economic instruments in a decentralized fiscal system in which externalities exist at the local level and in which subnational governments have the power to provide local public services as well as to choose tax instruments that can both finance these expenditures and correct the market failures of externalities

efficient bilateral taxation of externalities in the context of the example of a factory whose smoke emissions affect a near by laundry coase j law econ 3 1 44 1960 argued for taxing the laundry as well as the factory while baumol am econ rev 62 307 322 1972 argued for taxing only the factory consistent application of marginal cost pricing shows that the efficient tax on laundries is positive when the number of laundries is finite and that the tax approaches zero in the limit as the number of laundries approaches infinity the efficient tax on factories is bounded away from zero regardless of the number of factories our framework is an application of the vickrey clarke groves family of truth telling mechanisms that require each agent to bear the full social cost of changing the outcome that would have prevailed had she not participated in the decision until now the literature has not fully resolved the discrepancies between coase s and baumol s arguments and even contemporary textbooks on environmental economics and public economics do not offer correct and complete analyses

developing local currency bond markets for long term development financing in sub saharan africa this article discusses the role that local currency bond markets lcbms can play in the long term financing of sustainable development of sub saharan african ssa economies presents an empirical analysis of the factors which may hinder or promote the development of such markets in ssa using a new dataset for 27 ssa countries our findings support earlier research on ssa and other regions showing that lcbm development is related to country size larger banking systems greater trade openness better regulatory frameworks and rule of law foreign investor participation broadens the investor base and can give a boost to lcbm development yet it may also increase volatility of international capital flows hence with a view to the experience of emerging economies in other regions capital market liberalization should be pursued only very cautiously and in step with solid financial and institutional development

externalities a market model failure we focus here on a set of conceptual problems related to the accepted theory of externalities we are primarily concerned with difficulties that arise when a theoretical system is extended beyond its logical domain this is the practice in externality theory when the market model assuming independent agents is used to analyze physical interdependency the different kinds of dependencies obscure the standard use of the paretian analysis as the issues of rights and efficiency are mixed up the creation of emissions and the creation of externalities are further not held apart producing flows in the efficiency evaluations due to the interdependencies involved actions of both emitter and victim must be taken into account while searching for efficient policies finally we analyze the interrelationships between what is termed the internal structure of the market model and the annexed sphere of externalities we conclude that the accepted policy prescriptions both assume and demand no interrelationships between these two spheres we find the assumption unrealistic and inconsistent as concerns the basic foundations of the market model there are two main traditions addressing externalities the coasean and the pigovian this paper shows that both are vulnerable to the above critique thus the presumption that externality theory is now settled and coherent is seen to be without theoretical support

pigovian taxes which work in the small number case abstract an appropriately conceived pollution tax can achieve a pareto optimal equilibrium which is 1 stable in the presence of myopia 2 not subject to strategic manipulation even in the small number case and 3 resistant to inefficient cost shifting by the participants when transaction costs are low a considerable amount of confusion in the literature exists because different authors use different tax formulas often implicitly and different assumptions regarding conjectural behavior some of this confusion is cleared up by formally presenting various pigovian tax formulas explicitly considering whether there is cournot or stackleberg behavior and comparing the properties of the various configurations

fiscal federalism approach for controlling global environmental pollution this paper finds that optimal international carbon taxes are country specific and we can decompose a tax on a domestically produced carbon intensive commodity into a revenue tax a tax to control local atmospheric pollution and an international carbon tax it shows that an institutional arrangement for the world economy similar to the fiscal federalism in the federal countries can be useful to internalize the global externalities of atmospheric pollution

on optimal audit mechanisms for environmental taxes abstract we consider the auditing problem of an environmental enforcement agency with fixed audit resources how to decide which firms to audit after having observed the firms taxable emissions reports the goal of the agency is to implement the socially efficient emissions level the audit mechanism is the agency s sole choice variable while other variables such as the tax rate on emissions and the fine for non compliance are determined by other governmental actors the fines and budget of the agency are constrained in such a way that the common random audit mechanism fails to implement socially efficient emissions assuming perfect information among the firms we derive an optimal audit mechanism capable of implementing the socially efficient emissions level the optimal audit mechanism creates a contest exploiting the strategic interdependencies between the firms where the probability of winning not being audited for each firm depends on costly efforts their taxable emissions reports

estimating the effects of a time limited earnings subsidy for welfare leavers in the self sufficiency project ssp welfare demonstration members of a randomly assigned treatment group could receive a subsidy for full time work the subsidy was available for 3 years but only to people who began working full time within 12 months of random assignment a simple optimizing model suggests that the eligibility rules created an establishment incentive to find a job and leave welfare within a year of random assignment and an entitlement incentive to choose work over welfare once eligibility was established building on this insight we develop an econometric model of welfare participation that allows us to separate the two effects and estimate the impact of the earnings subsidy on welfare entry and exit rates among those who achieved eligibility the combination of the two incentives explains the time profile of the experimental impacts which peaked 15 months after random assignment and faded relatively quickly our findings suggest that about half of the peak impact of ssp was attributable to the establishment incentive despite the extra work effort generated by ssp the program had no lasting impact on wages and little or no long run effect on welfare participation

firm incentives to promote technological change in pollution control reply abstract the process of technological change in pollution control is broken into three basic steps innovation diffusion and optimal agency response firm incentives to promote these steps are then examined under five regulatory regimes direct controls emission subsidies emission taxes free marketable permits and auctioned marketable permits on a relative basis emission taxes and auctioned permits provide the highest firm incentives to promote technological change at times free permits generate lower incentives direct controls which are common regulatory tools usually provide the lowest relative firm incentives to promote technological change

reformulating taxes for an energy transition abstract an energy transition toward clean energy sources would reduce environmental impacts one proposal to trigger this energy transition uses economic instruments particularly environmental taxes this research studies the potential impact of taxes on electricity on the environment and the economy using a dynamic computable general equilibrium model for spain with energy and environmental extensions we assess their current impact on gdp growth energy use and a set of different pollutant emissions then we propose a reform that would foster an energy transition toward clean energies and assess their economic and environmental impact we find that only taxing the production of electricity by coal oil and natural gas can be better for the environment and economy than taxing all forms of electricity production in a revenue neutral context moreover the production of electricity by biomass though considered renewable is an important source of pollutant emissions and in these terms should have less importance in an energy transition

nonconvexity induced by external costs on production theoretical curio or policy dilemma this paper considers with a degree of scepticism the sweeping policy conclusions that can be found in the theoretical literature concerning nonconvexit ies in the social production set induced by external costs on firms this literature has provided proofs of the possibility that such nonconvexit ies exist but these proofs have readily been interpreted as a basis on which to judge the advisability of policies to control external costs 2 indeed a number of authors have felt able to proceed from specific theoretical examples of the existence of nonconvexity to the opinion that nonconvexity represents a general obstacle to policy one of the ma in themes will be to demonstrate that the theoretical possibility of the existence of a nonconvexity at a m icro level does not imply the existence of a m icro or a fortiori macro nonconvexity in the real world nor does it imply that any nonconvexity that does exist in reality is relevant to policy the intention is not to deny that nonconvexit ies may represent an obstacle to the efficient control of external costs in specific contexts but in order to establish the real world policy relevance of a nonconvexity it is necessary to verify its existence emp irically and to establish that it stands in a particular relationship to the no policy starting point

free riding carbon treaties and trade wars the role of domestic environmental policies this paper uses a calibrated general equilibrium model of north south trade with carbon emissions to explore the strategic open economy implications of price and quantity based instruments for co2 emission reduction we compute non cooperative environmental and trade policy equilibria and nash bargaining outcomes in environmental policies with side payments of cash results show that quotas can lead to higher internalization levels in a non cooperative zero tariff equilibrium in comparison with emission fees if tariffs are also chosen non cooperatively the form of policy instrument used affects equilibrium tariffs with quotas leading to lower trade barriers particularly under a regional carbon treaty

sharing the cost of global warming due to meteorological factors the distribution of the environmental damage due to climate change bears no relationship to that of global emissions we argue in favor of osetting this discrepancy and propose a global insurance scheme to be ncanced according to countries respon sibility for climate change because ghg decay very slowly we argue that the actual burden of global warming should be shared on the basis of cumulated emissions raher than sharing the expected costs of actual emissions as in a pigovian taxation scheme we characterize new versions of two well known cost sharing schemes by adapting the responsibility theory of bossert and fleurbaey 1996 to a context with externalities j e l classi cation d62 d63 q54

pigou and coase in retrospect this paper documents through direct quotation and mathematical analysis the parallels between both the logic and the policy conclusions of a c pigou and r h coase it is shown that pigou s analysis encompasses the essential features of both the nature of the firm and the problem of social cost but more importantly pigou lays out the logical connection between the two an underlying theme is that particularly in the case of pigou much substance has been lost in mathematical translation had that substance not been forgotten the 1960 coase would not have had to attack pigou c 1993 academic press inc copyright 1993 by oxford university press

the effects of youth employment evidence from new york city lotteries programs to encourage labor market activity among youth including public employment programs and wage subsidies like the work opportunity tax credit can be supported by three broad rationales they may i provide contemporaneous income support to participants ii encourage work experience that improves future employment and or educational outcomes of participants and or iii keep participants out of trouble we study randomized lotteries for access to the new york city nyc summer youth employment program syep the largest summer youth employment program in the united states by merging syep administrative data on 294 100 lottery participants to irs data on the universe of u s tax records to new york state administrative incarceration data and to nyc administrative cause of death data in assessing the three rationales we find that i syep participation causes average earnings and the probability of employment to increase in the year of program participation with modest contemporaneous crowdout of other earnings and employment ii syep participation causes a modest decrease in average earnings for three years following the program and has no impact on college enrollment and iii syep participation decreases the probability of incarceration and decreases the probability of mortality which has important and potentially pivotal implications for analyzing the net benefits of the program jel codes j13 j45 j38 j21

zoning and the distribution of location rents an empirical analysis of harris county texas the coase theorem presents two criteria for evaluating regulation regulations efficiency relative to private solutions and how the regulation affects the distribution of wealth previous studies of the impact of municipal zoning have focused on coase s first criteria whether zoning raises land values overall this study estimates the transfer of wealth between owners of existing homes that results from the creation of a municipal zoning ordinance we find that property best suited to residential use gains in value while property with relatively higher potential as commercial property experiences a decline in the value we find that zoning is distributive

test based promotion policies dropping out and juvenile crime abstract over the past decade several states and school districts have implemented accountability systems that require students to demonstrate a minimum level of proficiency through standardized tests with many states and school districts ending social promotion policy makers and researchers have gained renewed interest in the role of grade retention and remedial education in us schools this paper examines the potential effects of summer school and grade retention on high school completion and juvenile crime to do so we use administrative data from a number of state agencies in louisiana and a regression discontinuity design to analyze louisiana s statewide test based promotion policy administered to students in fourth and eighth grades our results indicate that potential grade retention increases the propensity of a student to drop out of school in addition eighth grade remedial education assignment in the form of summer school appears to provide a positive benefit by decreasing the likelihood that a student drops out as for fourth grade students however we do not find any effect of summer school assignment finally for eighth graders we find that the net effect of the test based promotion policies is to decrease the probability of being convicted of a juvenile crime

does job corps work impact findings from the national job corps study this paper presents findings from an experimental evaluation of job corps the nation s largest training program for disadvantaged youths the study uses survey data collected over four years and tax data over nine years on a nationwide sample of 15 400 treatments and controls the job corps model has promise program participation increases educational attainment reduces criminal activity and increases earnings for several postprogram years based on tax data however the earnings gains were not sustained except for the oldest participants nonetheless job corps is the only federal training program that has been shown to increase earnings for this population

externalities in a regulated industry the aircraft noise problem airline noise is an externality in the traditional sense of being a byproduct of normal economic activity it affects the population around airports in single event bundles and cumulatively the transient nature of noise itself is unlike most other externalities as with the others however general improvements in technology and increases in population have made the situation more difficult to tolerate the combination of these things has led to a critical situation for the affected population since it involves its physical and mental health from among the various methods of dealing with externalities we choose the effluent charge scheme it generally allows each firm to incorporate the environmental standard into its marginal operating choices if each firm makes efficient decisions then the cost to society of achieving an environmental standard will be a minimum in this paper there are two modifications of the traditional charge scheme one is that because of the well known difficulties in specifying and estimating social costs we use the estimated direct noise abatement costs of achieving the environmental standard the second is that airlines cannot be necessarily thought of as cost minimizers the charges used for the control of airline noise are generated as shadow prices in a simple linear programming model solution to the problem involves choosing a mix of noise abating options that achieves proposed environmental standards at least cost additional bounds on the problem are limitations on service reductions and rate of return ror oni investment regulation the data sources used for the program were generally fragmentary and incomplete for our purposes after calculating a noise charge for a hypothetical airport we discuss the implementation and ramifications of the charge plan in the regulated airline industry included is a discussion of the link between noise abatement and fuel consumption

the effect of production versus consumption based emission tax under demand uncertainty abstract emission tax is an instrument widely adopted by countries and regions to incentivize emission abatement by emission intensive firms including manufacturers however policies differ in how they allocate emission responsibilities among stakeholders for example the chile emission tax directly penalizes manufacturers for the emissions they generate during their production production based emission tax whereas the sweden electricity emission tax penalizes the consumption of electricity rather than its production consumption based emission tax these two methods have potentially varying implications on manufacturers profits their emission abatement decisions as well as the resulting emission levels especially when demand uncertainty is involved in this paper we investigate the impact of the two distinct methods by studying a profit maximizing manufacturer facing stochastic demand under either production or consumption based emission tax the manufacturer s optimal decisions on its selling price production quantity and emission abatement investment are derived perhaps surprisingly we show that under either tax it is possible for an increase in the emission tax to discourage the manufacturer from investing in emission abatement the impact of tax rate abatement technology efficiency and demand uncertainty on the manufacturer s profitability and abatement decision are also studied interestingly higher demand uncertainty may motivate the manufacturer to invest more in emission abatement under production based emission tax using a numerical example of an electricity power generator we offer further insights into the comparison between the two taxes and find that there exist cases for either tax to dominate the other in terms of both profit and emissions

carbon abatement in the fuel market with biofuels implications for second best policies a carbon tax on fuel would penalize carbon intensive fuels like gasoline and shift fuel consumption to less carbon intensive alternatives like biofuels since biofuel production competes for land with agricultural production a carbon tax could increase land rents and raise food prices this paper analyzes the welfare effect of a carbon tax on fuel consisting of gasoline and biofuel in the presence of a labor tax with and without a biofuel subsidy the market impacts of a carbon tax are also compared with that of a subsidy findings show that if a carbon tax increases biofuel demand the tax interaction effect due to higher fuel prices is exacerbated by higher land rent and food prices and greater erosion of the carbon tax base thus the second best optimal carbon tax for fuel is lower with biofuel in the fuel mix especially if biofuel is subsidized

the economics of renewable energy support abstract this paper uses theoretical and numerical economic equilibrium models to examine optimal renewable energy re support policies for wind and solar resources in the presence of a carbon externality associated with the use of fossil fuels we emphasize three main issues for policy design the heterogeneity of intermittent natural resources budget neutral financing rules and incentives for carbon mitigation we find that differentiated subsidies for wind and solar while being optimal only yield negligible efficiency gains policies with smart financing of re subsidies which either relax budget neutrality or use polluter pays financing in the context of budget neutral schemes can however approximate socially optimal outcomes our analysis suggests that optimally designed re support policies do not necessarily have to be viewed as a costly second best option when carbon pricing is unavailable

the direction of causality between financial development and economic growth abstract this paper employs the geweke decomposition test on pooled data of 109 developing and industrial countries from 1960 to 1994 to examine the direction of causality between financial development and economic growth the paper finds that 1 financial development generally leads to economic growth 2 the granger causality from financial development to economic growth and the granger causality from economic growth to financial development coexist 3 financial deepening contributes more to the causal relationships in the developing countries than in the industrial countries 4 the longer the sampling interval the larger the effect of financial development on economic growth 5 financial deepening propels economic growth through both a more rapid capital accumulation and productivity growth with the latter channel being the strongest

production uncertainty and pollution there has been considerable interest in two sector models in which the production of one of the goods is subject to uncertainty the major papers in this area are by rothenberg and smith 13 batra 1 britto 3 diamond 5 mills 12 and harford and park 8 in the latest of these papers harford and park 8 41 build on a model in mills 12 to show that if constant relative risk aversion r which is mathematically analogous to the pratt arrow measure is less than exceeds or equal to unity the direction of efficient resource flow under uncertainty as compared to certainty is away from the risky sector toward the risky sector or unchanged respectively in their model as in mills 12 the preferences of consumers are represented by a community expected utility function in the present two sector model the risky sector is an industry that is adversely affected by air pollution which is a by product of production in the other industry although there is a deterministic relation between the output and emissions of the polluting stable sector the damage caused to the other sector as a result of any given level of emissions depends upon random variables such as mixing height and wind velocity and is therefore stochastic it is not intuitively obvious whether the results of harford and park 8 hold if the uncertainty in the risky sector is the consequence of production in the stable sector in fact there is substantial dissimilarity in the results if the measure of risk aversion r is less than unity the efficient direction of resource flow is generally though not always toward the risky polluted sector if r equals unity the results also differ with resources shifting under uncertainty in the direction of the risky polluted sector only if r exceeds unity are the results always the same in both models with resources flowing toward the risky sector this paper presents the marginal condition such that under uncertainty the optimal combination of outputs includes less of the stable polluting good and more of the risky pollution sensitive good than would be the case if pollution damage were anticipated with certainty if this marginal condition does not hold the risk averse community may prefer either more or less of the polluting good a narrowed interpretation of the marginal condition is then used to predict the special case in which the efficient flow of resources under uncertainty is toward the polluting sector

political deadlocks and distributional information the value of the veil contractarian normative theory relies on the veil of ignorance construct to generate the political consensus required for its theories of justice by eliminating distributional information the veil is presumed to facilite consensus building by reducing conflict over the distributional effects of proposed constitutional rules or institutions this paper explores the extent to which excessive distributional information might also impede the ordinary day to day decision making of democratic institutions our analysis suggests that distributive information makes political deadlocks under majority rule more likely statistical evidence suggests that the efficacy of the u s congress has been reduced by the dramatic increase in distributional information made available to it over the past twenty five years

training wages and sample selection estimating sharp bounds on treatment effects this paper empirically assesses the wage effects of the job corps program one of the largest federally funded job training programs in the u s even with the aid of a randomized experiment the impact of a training program on wages is difficult to study because of sample selection a pervasive problem in applied microeconometric research wage rates are only observed for those who are employed and employment status itself may be affected by the training program this paper develops an intuitive trimming procedure for bounding average treatment effects in the presence of sample selection in contrast to existing methods the procedure requires neither exclusion restrictions nor a bounded support for the outcome of interest identification results estimators and their asymptotic distribution are presented the bounds suggest that the program raised wages consistent with the notion that the job corps raises earnings by increasing human capital rather than solely through encouraging work the estimator is generally applicable to typical treatment evaluation problems in which there is nonrandom sample selection attrition copyright wiley blackwell

externality regulation and the monopoly firm abstract differences in strategic assumptions lead to predictable variations in the conclusions one may draw the formal theory of monopoly power and externalities reflects this variability in assumptions and conclusions this paper contains a unified model of monopoly power marketable product output and externality abatement

steering the climate system using inertia to lower the cost of policy common views hold that the efficient way to limit warming to a chosen level is to price carbon emissions at a rate that increases exponentially we show that this hotelling tax on carbon emissions is actually inefficient the least cost policy path takes advantage of the climate system s inertia to delay reducing emissions and allow greater cumulative emissions the efficient carbon tax follows an inverse u shaped path and grows more slowly than the hotelling tax economic models that assume exponentially increasing carbon taxes are overestimating the cost of limiting warming overestimating the efficient near term carbon tax and overvaluing technologies that mature sooner

providing adequate economic incentives for bioenergies with co2 capture and geological storage abstract knowing that carbon capture and storage ccs could play an important role in reducing emissions it is important to have a good understanding of this role and the importance of environmental policies to support carbon capture and geological storage from bioenergies beccs to date ccs technologies are not deployed on a commercial level and policy instruments should be used to provide incentives to firms to use these technologies to reduce pollution the aim of this paper is to compare the cost efficiency of several incentive based instruments a fossil fuel tax an emissions tax a cap and trade system and a subsidy on captured emissions needed to spur the adoption of ccs and beccs using a dynamic general equilibrium model this type of model has become the standard for assessing economy wide impacts of environmental and technological policies the study shows that beccs will be deployed only if a specific subsidy per unit of biomass emissions captured with a ccs technology is available we show also that the two most cost efficient instruments for achieving a given emissions reduction target are a specific subsidy that rewards captured emissions and a carbon tax whose revenues are recycled to subsidize beccs

greenhouse gas abatement cost curves of the residential heating market a microeconomic approach in this paper we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector our research is based on a system dynamics microsimulation of private households investment decisions for heating systems to the year 2030 by accounting for household specific characteristics we investigate the welfare costs of different abatement policies in terms of the compensating variation and the excess burden we investigate two policies i a carbon tax and ii subsidies on heating system investments we deduce abatement cost curves for both policies by simulating welfare costs and greenhouse gas emissions to the year 2030 we find that i welfare based abatement costs are generally higher than pure technical equipment costs ii given utility maximizing households a carbon tax is the most welfare efficient policy and iii if households are not utility maximizing a subsidy on investments may have lower marginal greenhouse gas abatement costs than a carbon tax

the value of school facility investments evidence from a dynamic regression discontinuity design author s cellini stephanie riegg ferreira fernando rothstein jesse abstract despite extensive public infrastructure spending surprisingly little is known about its economic return in this paper we estimate the value of school facility investments using housing markets standard models of local public goods imply that school districts should spend up to the point where marginal increases would have zero effect on local housing prices our research design isolates exogenous variation in investments by comparing school districts where referenda on bond issues targeted to fund capital expenditures passed and failed by narrow margins we extend this traditional regression discontinuity approach to identify the dynamic treatment effects of bond authorization on local housing prices student achievement and district composition our results indicate that california school districts underinvest in school facilities passing a referendum causes immediate sizable increases in home prices implying a willingness to pay on the part of marginal homebuyers of 1 50 or more for each 1 of capital spending these effects do not appear to be driven by changes in the income or racial composition of homeowners and the impact on test scores appears to explain only a small portion of the total housing price effect c 2010 by the president and fellows of harvard college and the massachusetts institute of technology

pigou and coase a mathematical reconciliation abstract this paper provides a rigorous statement of the coase theorem and establishes a formal equivalence between abstract allocative mechanisms attributed to coase and pigou the model proceeds from output functions that reduce to production functions in special cases thereby capturing effects that are obscured by conventional production and cost functions the model also emphasizes fundamental differences in the characteristics of inputs particularly land that are implied in the construction of externality stories finally the model embodies a clear distinction between local e g nuisance and global e g pollution externalities the coase theorem as stated is valid only in the former case

how does your kindergarten classroom affect your earnings evidence from project star in project star 11 571 students in tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade this article evaluates the long term impacts of star by linking the experimental data to administrative records we first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27 college attendance home ownership and retirement savings we then document four sets of experimental impacts first students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes class size does not have a significant effect on earnings at age 27 but this effect is imprecisely estimated second students who had a more experienced teacher in kindergarten have higher earnings third an analysis of variance reveals significant classroom effects on earnings students who were randomly assigned to higher quality classrooms in grades k 3 as measured by classmates end of class test scores have higher earnings college attendance rates and other outcomes finally the effects of class quality fade out on test scores in later grades but gains in noncognitive measures persist

an analysis of minimum frontage zoning to preserve lakefront amenities the development of lakefront property in northern wisconsin has prompted in several towns minimum frontage zoning stricter than the state standard such zoning generates an economic loss by constraining development development effect and an economic gain by preserving environmental amenities amenity effect estimation of a hedonic price function for lakefront property in northern wisconsin quantifies these competing effects the estimation indicates that at the current margin the economic loss from the development effect is negligible and the economic gain from the amenity effect may be considerable raising frontage prices by an average of 21 5

retail store density and the cost of greenhouse gas emissions the density size and location of stores in a retailer s network influences both the retailer s and the consumers costs with stores few and far between consumers must travel a long distance to shop whereas shopping trips are shorter with a dense network of stores the layout of the retail supply chain is of interest to retailers who have emission reduction targets and urban planners concerned with sprawl are small local shops preferred over large big box retailers a model of the retail supply chain is presented that includes operating costs such as fuel and rent for floor space as well as a cost for environmental externalities associated with carbon emissions a focus on exclusively minimizing operating costs may substantially increase emissions by 67 in one scenario relative to the minimum level of emissions a price on carbon is an ineffective mechanism for reducing emissions the most attractive option is to improve consumer fuel efficiency doubling the fuel efficiency of cars reduces long run emissions by about one third whereas an improvement in truck fuel efficiency has a marginal impact on total emissions this paper was accepted by yossi aviv operations management

estimation of limited dependent variable models with dummy endogenous regressors applied economists have long struggled with the question of how to accommodate binary endogenous regressors in models with binary and nonnegative outcomes i argue here that much of the difculty with limited dependent variables comes from a focus on structural parameters such as index coefcients instead of causal effects once the object of estimation is taken to be the causal effect of treatment several simple strategies are available these include conventional two stage least squares multiplicative models for conditional means linear approximation of nonlinear causal models models for distribution effects and quantile regression with an endogenous binary regressor the estimation strategies discussed in the article are illustrated by using multiple births to estimate the effect of childbearing on employment status and hours of work

the effect of emission taxes and abatement subsidies on market structure comment abstract conrad and wang 1993 international journal of industrial organization 11 499 518 determine that a tax on emissions decreases the total output of a polluting industry but if demand is sufficiently inelastic can increase the number of firms in that industry this follows from their proposition that the tax reduces the scale of the polluting firm in contrast the scale of the polluting firm in the present model increases when there are increasing returns to scale in abatement whereas conrad and wang extend their results to cases of monopolistic competition the present paper is confined to perfect competition but extends the analysis to the pollution damaged industry

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

coasean bargaining in the presence of pigouvian taxation coasean arguments against the pigouvian perspective are well established a central tenet in this criticism argues that a pigouvian tax may be a source of inefficiency if parties were to bargain in the presence of a pigouvian tax allocative inefficiencies would occur the so called buchanan stubblebine turvey theorem by analyzing a coasean environment where the appropriation of property rights is costly we show coasean bargaining in the presence of a pre existing pigouvian tax may be superior this has implications for policy where dual regulatory environments exist such as regulation at the state and federal level as well as environmental liability and litigation

elements of an economic justification for municipal zoning abstract the possibility that externalities will produce a nonconvexity in the social production set limits the application of both the coase and pigou solutions for achieving an optimal allocation of land resources conditions on relative land prices are derived which indicate that external effects are strong enough to introduce a nonconvexity into the production set these conditions were not fulfilled in a sample of single family and multifamily dwellings in foster city california this does not preclude the possibility that they are fulfilled in cases of more severe external effects

green fiscal reform in sweden econometric assessment of the carbon and energy taxation scheme abstract empirical econometric assessment of environmental policy effectiveness is capable of demonstrating which tools have been helping to achieve the desired effect of reducing harmful emissions or stimulating technological change this paper employs an econometric approach to analyse the effectiveness of energy and carbon taxes in sweden the country which was one of the first to introduce a co2 tax as well as an extensive environmental tax reform the results showed that taken in isolation a co2 tax was not sufficient to result in a significant change in co2 emissions in sweden except in the case of petrol on the other hand energy taxes for coal and lpg have been statistically significantly effective it was also clear that a technological innovation in the form of development of nuclear and hydro energy played a significant role in reducing co2 emissions and higher oil price was also important in reducing national co2 emissions in sweden at the same time renewable energy excluding hydro a more recent innovation has not been a statistically significant driver of co2 emissions reduction perhaps due to the fact that wind and solar play a much lesser role in sweden at the moment the net electricity imports from other countries have contributed positively towards reducing co2 emissions in sweden while the use of coal and biomass tended to increase co2 emissions compared to the ex ante modelling results from the literature review the findings confirm the role of environmental taxation as a viable policy instrument effective in reducing co2 emissions in sweden although point towards a more nuanced picture the paper raises important policy questions focused on the effectiveness of environmental policy tools

the economic theory of zoning a critical review municipal zoning regulations are the most important way in which local governments affect housing markets numerous studies have been undertaken to analyze the impact of zoning on housing and land prices on population density and on welfare however despite the volume of previous research there is little agreement on the effects of zoning or how to properly analyze those effects several papers have reviewed the empirical literature on zoning this review focuses on the theory of zoning specifically on how zoning is modeled especially whether zoning is embedded in an urban model and the implications derived from these models for the impact of zoning on welfare and housing prices we divide the effects of zoning on economic agents into six broad categories supply side effects demand side effects tiebout effects externality effects endogenous zoning and rent seeking behavior supply side effects concern how zoning affects the suppliers of housing services and the land market demand side effects concern how zoning affects consumers choice of the optimal consumption bundle especially the choice of housing characteristics tiebout effects result from consumer mo

a review essay on isabel sawhill s generation unbound drifting into sex and parenting without marriage and laurence steinberg s age of opportunity lessons from the new science of adolescence sawhill and steinberg approach risky behavior among youth from two different angles steinberg argues for intervention during the adolescent years to alter behavior in ways that prioritize patience and self regulation while sawhill advocates interventions that mitigate the negative effects of risky behavior both argue that disadvantaged youth suffer worse consequences as a result of risky behavior and therefore stand to gain the most from interventions while the authors develop strong arguments for adolescent interventions the existing evidence on their effectiveness is less compelling to reconcile the promise with the reality i argue that growing up in environments of significant uncertainty reduces the returns to forward thinking behavior in the daily lives of disadvantaged youths interventions to develop adolescent decision making skills so as to reduce risky behavior will not be effective if they are inconsistent with the incentives generated by a local environment that is often characterized by uncertainty

active labor market policy evaluations a meta analysis this article presents a meta analysis of recent microeconometric evaluations of active labour market policies we categorise 199 programme impacts from 97 studies conducted between 1995 and 2007 job search assistance programmes yield relatively favourable programme impacts whereas public sector employment programmes are less effective training programmes are associated with positive medium term impacts although in the short term they often appear ineffective we also find that the outcome variable used to measure programme impact matters but neither the publication status of a study nor the use of a randomised design is related to the sign or significance of the programme estimate

the impact of tax reform on new car purchases in ireland we examine the impact of recent tax reforms in ireland on private car transport and its greenhouse gas emissions a carbon tax was introduced on fuels and purchase vehicle registration and ownership motor taxes were switched from engine size to potential emissions we use a demographic model of the car stock by age size and fuel and a car purchase model that reflects the heterogeneous distribution of mileage and usage costs across various engine sizes the model shows a dramatic shift from petrol to diesel cars particularly for large engines the same pattern is observed in the latest data on car sales this has a substantial impact on tax revenue as car owners shift to the lower tax rates the tax burden has shifted from car ownership to car use and that the overall tax burden on private car transport falls as diesel engines are more fuel efficient than petrol engines carbon dioxide emissions fall modestly or if we consider the rebound effect of travel costs on mileage minimally from the perspective of the revenue the costs per tonne of carbon dioxide avoided are very high

the inefficiency of private adaptation to pollution in the presence of endogenous market structure the paper considers an industry where production costs rise due to pollution but where this effect can be partially off set by investing in adaptation as a private good the focus is not on external effects but industries where economies of scale are introduced from adapting to pollution the structure of the resulting oligopolistic market is endogenous since the level of adaptation is chosen by the firms the analysis of externalities usually disregards defensive or adaptation measures with a few exceptions that point to considerable complications the present debate on adaptation to climate change shows the importance of understanding defensive measures i show that the market failure caused by economies of scale leads to production costs above the social optimum i e to under adapation when pollution increases adaptation only increases if demand is price inelastic otherwise welfare loss from market failure decreases with pollution the total welfare loss is only convex if demand is price inelastic and the influence of pollution on production costs is stronger than the influence of adaptation concave welfare loss has crucial implications for abatement policies

controlling the monopolistic polluter nihilism or eclecticism abstract this paper is concerned with the consequences of pollution control when the polluter is a monopolist who can choose between abating pollution by reducing output and by adopting a less polluting technology it is suggested that the risk of welfare losses resulting from control policy is lower when technology is flexible than when it is rigid nevertheless some risk does remain so the paper concludes with a discussion of the possible use of selective control instruments to keep the risk to a minimum

peer pressure experimental evidence from restroom behavior we provide experimental evidence on the effect of peer pressure on individual behavior specifically we study the effect of being exposed to an observer in a public restroom on handwashing and urinal flushing behavior our estimates show that being exposed to an observer increases the probability of handwashing by 13 percentage points and the probability of urinal flushing by 15 percentage points given that handwashing and urinal flushing have social benefits that exceed individual benefits our findings provide support for peer pressure as an additional way of addressing the social suboptimality arising from externalities jel c91 c93

a note on externalities and taxation the purpose of this paper is to explore the distributional aspects of a tax that is imposed in order to correct the detrimental effects of a production externality in the framework of a two sector general equilibrium model we show that harberger s classic results of tax incidence may change considerably because of the presence of the externality we also show that the tax is effective in reducing the detrimental effect of the externality although the return of the taxed factor may rise relative to the return of the untaxed factors

taxing average emissions to overcome the shutdown problem abstract the paper shows that the optimal regulation of stock pollutants can require fluctuating emissions even in the absence of uncertainty the optimum cannot be implemented by the usual pigouvian flow tax since it leads to a shutdown problem a remedy for the problem is to use a linear tax given by a mechanism that effectively taxes average emissions over time an alternative is to use tax schedules depending on cumulative emissions over a short period of time a calibration using cost estimates of greenhouse gases suggests that potential gains from fluctuating carbon emissions are considerable

fundamental nonconvexities in arrovian markets and a coasian solution to the problem of externalities abstract d starrett j econ theory 4 1972 180 199 argues that the presence of externalities implies fundamental nonconvexities which cause arrow markets to fail while this is true we argue this failure is due to the structure of the arrovian markets that starrett uses and not to the presence of externalities as such we provide an extension of a general equilibrium public goods model in which property rights are explicitly treated nonconvexities are not fundamental in this framework we define a notion of coasian equilibrium for this economy and show first and second welfare theorems in this context the first welfare theorem is a type of coase theorem journal of economic literature classification numbers d62 h41

messy marginal costs internal pricing of environmental aspects on the firm level abstract internal pricing of environmental aspects is usually not embedded in management accounting systems therefore we first show that pricing from a corporative perspective is possible and applicable contrary to common belief we also show that marginal costs curves of environmental aspects are often not monotonic and price changes are highly context specific we introduce a model that addresses different environmental aspects that translate into constraints or change direct cost factors in the objective function environmental constraints originate from different types of limit values concerning emissions and production processes as well as restraining the potential environmental damage as the outcome of ecological valuation methods direct cost factors include the taxation of emissions and costs stemming from being involved in the emissions trading market our model allows for calculating the marginal indirect costs of these environmental aspects as the constraints might enforce factor and product substitutions we show that the marginal costs differ substantially from the direct costs and do not follow a predictable pattern sensitivity analysis and parametric programming are applied to set up an internal pricing and cost allocation scheme for environmental aspects specifically focusing on the pricing of emissions resources and processes of production and recycling the model s implications on corporate decision making are illustrated by a numerical example that draws on the opportunity of process substitution e g producing a product on different machines even though we cannot use original data for proprietary reasons such settings are highly relevant in industry and the energy sector

regulation of externalities in an open economy abstract this paper considers the ranking of second best policies for an open economy that regulate externalities arising from the production of an exportable pesticides and other chemicals used in us agriculture are good examples uncertainty originates from three sources random shifts in production cost and external costs and the random fluctuations in the world price of a traded good world prices become unreliable indicators of comparative advantages in the presence of external costs nonintervention of free trade can encourage excessive production and exports of commodities with spurious comparative advantages the paper analyses the properties of the optimal state contingent tax or first best tax which is difficult to implement these properties are then used to rank second best policies that are determined before uncertainties are resolved it is shown that ex ante taxes and quotas are equivalent when the marginal external cost is subject to random shifts when the world price is uncertain the optimal ex ante effluent charge dominates the optimal quantity standard when the marginal production cost of the exportable is subject to random shifts the ranking of second best policies is generally ambiguous
