when is external debt sustainable the article empirically examines the determinants of debt distress defined as periods in which countries resort to any of three forms of exceptional finance significant arrears on external debt paris club rescheduling and non concessional international monetary fund lending probit regressions show that three factors explain a substantial fraction of the cross country and time series variation in the incidence of debt distress the debt burden the quality of policies and institutions and shocks the relative importance of these factors varies with the level of development these results are robust to a variety of alternative specifications and the core specifications have substantial out of sample predictive power the quantitative implications of these results are examined for the lending strategies of official creditors

intergenerational equity and sustainability abstract this paper explores the limitations of conventional economic analysis of intergenerational problems and examines some of the alternatives suggested in the literature it is argued that proper consideration of future generations has at least three requirements first when future costs and benefits are considered it should be taken into account that they are to be enjoyed by different generations second the sustainability requirement should be adopted this represents an equity commitment to the future and implies the recognition that future generations have the right to nondeteriorated ecological and economic capacity the paper studies the ways in which the recognition of these rights might be incorporated into economic evaluation and management third an appropriate institutional network to enforce the recognition of these rights in decision making processes should be constituted its design and necessary functions are also analyzed

adoption of an imf programme and debt rescheduling an empirical analysis the existence of an empirical relationship between the adoption of an imf programme and the concession of a debt rescheduling by commercial and official creditors is tested using a bivariate probit model if countries who have arrangements with the imf are more likely than others to obtain a rescheduling of their external debt we could conclude that the adoption of an imf programme could work as a sort of signal of a country s good willingness which is thus rewarded with the debt relief the results confirm the existence of a significant effect of the adoption of an imf programme on the subsequent concession of a debt rescheduling by creditors

co2 emissions from china s power sector at the provincial level consumption versus production perspectives abstract the chinese electricity sector plays an important role in domestic co2 mitigation efforts due to its large contribution to overall emissions however primary energy resources used for electricity generation are not evenly distributed across the country such a supply and demand mismatch in reality results in large parts of electricity to be transferred from economically less developed provinces in the west to economic growth centres in the east a literature review shows that the emissions embodied in electricity transfer within china have not been explicitly studied although in fact they cause a shift of environmental pollution away from economically well off provinces to resource rich and less developed provinces therefore it is critical for policy makers to address this issue under such a circumstance a bottom up model is developed to calculate direct co2 emissions embodied in electricity export and import between chinese provinces it helps quantifying emissions from the power sector associated with both production and consumption perspectives and sheds lights on the environmental impact of regional supply and demand mismatch in china results show that the difference between consumption and production based co2 emissions from electricity sector in some provinces were higher than the total co2 emissions from electricity sector in netherlands in the case of beijing or as high as the total co2 emission from france s electricity sector in the case of guangdong based upon chinese realities policy implications and suggestions are made such as how to set up appropriate emission reduction targets for electricity sector at provincial level and the inclusion of consumption emissions in designing china s cap and trade mechanism the methodology and findings may be useful for investigation of embodied emissions throughout various regions of the world

bargaining around cost benefit standards abstract injurers often purchase the property of potential victims to avoid liability or to comply with regulations this paper shows that injurers subject to cost benefit standards could profit from buying out victims even if they attach no value to the victims property because buyouts allow injurers to take fewer precautions a buyout of one victim produces a negative externality for the remaining victims injurers can consequently exploit victims and thereby reduce social welfare by adopting a divide and conquer strategy or by negotiating with victims sequentially perhaps surprisingly buyouts may reduce social welfare and victims joint profits even if victims make simultaneous or sequential take it or leave it buyout demands to the injurer

sustainability limited substitutability and non constant social discount rates abstract the paper shows how limited substitutability in consumption between different classes of goods affects the magnitude and time development of social discount rates it decomposes the discount rates into an absolute growth and a relative growth or substitutability effect the paper relates between good and intertemporal substitutability to the notions of weak and strong sustainability it analyzes under which circumstances low as opposed to high between good substitutability increases the weights given to long run environmental services

reconciling sustainability and discounting in cost benefit analysis a methodological proposal abstract the incorporation of the intergenerational equity objective has rendered the traditional cost benefit analysis cba approach obsolete for the evaluation of projects presenting an important number of environmental externalities and for those whose impacts extend throughout a long period of time based on the assumption that applying a discount rate rewards current consumption and therefore that it is only possible to introduce a certain intergenerational equity in a cost benefit analysis in this work we propose an approach to discounting based on a different rationale for tangible and intangible effects we designed two indicators of environmental profitability a the intergenerational transfer amount ita which quantifies in monetary units what the current generation is willing to pass on future generations when an environmental restoration project is carried out and b the critical environmental rate cer measures the implicit environmental profitability these concepts were tested through an empirical case study pertaining to the assessment of an erosion control project in the southeast of spain the results yield traditional profitability indicators that are higher and probably closer to the real values set by the contemporary society the information provided by the environmental profitability indicators proposed renders more transparency to the quantification of the levels of intergenerational equity applied thereby facilitating the difficult reconciliation of the cba technique with the objective of sustainability

three approaches to predict the timing and quantity of ldc debt rescheduling the performance of three approaches to predict the timing and quantity of ldc debt rescheduling is examined the balance sheet approach the traditional macro approach and the structural approach results show that the balance sheet approach performs better

pollution claim settlements reconsidered hidden information and bounded payments abstract a principal s production decision imposes a negative externality on an agent the principal may be a pollution generating firm the agent may be a nearby town the principal offers a contract to the agent who has the right to be free of pollution then the agent privately learns the disutility of pollution finally a production level and a transfer payment are implemented suppose there is an upper bound possibly zero on payments that the agent can make to the principal in the second best solution there is underproduction for low cost types while there is overproduction for high cost types in contrast to standard adverse selection models of pollution claim settlements there may thus be too much pollution compared to the first best solution

environmentalism democracy and pollution control this paper makes two empirical contributions to the literature based on predictions generated by a lobby group model first we investigate how environmental lobby groups affect the determination of environmental policy in rich and developing countries second we explore the interaction between democratic participation and political electoral competition the empirical findings suggest that environmental lobby groups tend to positively affect the stringency of environmental policy moreover political competition tends to raise policy stringency in particular where citizens participation in the democratic process is widespread

valuing the future recent advances in social discounting the perplexing issue of discounting prescriptive economics requires that unless there are very good reasons to the contrary economic policy should be based on the principle that individuals preferences should count indeed the entire body of welfare economics centres round the formal identity of the statement x prefers a to b and the statement x has higher welfare in a rather than b this combination of a seemingly innocuous and democratic value judgement preferences should count and a formal definition about the meaning of welfare improvement involves many complications the entire history of policy analysis focuses on those complications whose preferences should count over what time period what constitutes a legitimate attenuation of the basic value judgement one of the problem areas concerns timediscounting the process whereby society places a lower value on a future gain or loss than on the same gain or loss occurring now the rationale for time discounting follows logically from the basic value judgement of welfare economics if people s preferences count and if people prefer now to the future those preferences must be integrated into social policy formulation time discounting is thus universal in economic analysis but it remains as it always has controversial the controversy has a parallel in another form of discounting spatial discounting when translated into economic terms the ethical principle

the energy policy outlets for community acceptance of ecological investment in china abstract policy implication about satisfactions of energy use and housing are much sensitive to social discount rate changes which can increase the dissatisfaction of residential happiness because of an increasing price mechanism when per capita resource faces to decline we thus estimate the private expected rates of return on ecological investment to improve urban and peri urban environmental infrastructures are about to 7 54 and 18 37 respectively the endogeneities of income and saving rise can increase the uncertain part of private discount rate up to a higher estimated subjective social discount rate about 14 46 for urban or 8 86 for peri urban environmental infrastructures improvement the estimated time preference rate can be raised from 1 to 1 72 the prediction of these estimated private discount rate can ease at least 20 of the dissatisfaction to energy use and 10 of the dissatisfaction to housing conditions therefore we suggest opening the landscape rights to individual willingness to invest and providing options to let people pay a part of their pensions for temporal permits to living in some well served villages where are close to the places with advanced environmental amenities and being supported by central planning policy via the crowdfunding operation for improving environmental quality

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

victim compensation revisited abstract the siting of an efficient noxious facility may decrease social welfare if people care about horizontal equity the facility decreases the relative attractiveness of the host city decreasing land rent in the host city and increasing land rent elsewhere victim compensation which promotes horizontal equity at the expense of efficiency will increase social welfare if a the demand for land is relatively inelastic b the demand for the output of the noxious facility is relatively elastic and c the preferences for horizontal equity are relatively strong

do plants decrease pollution reduction efforts during a recession evidence from upstate new york chemical plants during the us great recession us communities often experience economic hardship with plant or business closings contributing to high unemployment rates in this circumstance communities and local governments may prioritize economic recovery over environmental improvement thereby weakening community and government pressure against polluting plants in an attempt to explore the concern this study examines the impact of local economic downturn on nearby chemical plants toxic release reduction behavior a total of 351 plants in upstate new york and their toxic release inventory data were analyzed for 5 years 2006 2010 the results show plants toxic release reduction efforts were reduced when unemployment and plant closing rates were high therefore the findings highlight a possible limitation to regulatory approaches that rely on public pressure to motivate better environmental performance

house values incomes and industrial pollution abstract this paper analyzes the effect of polluting manufacturing facilities on the economic characteristics of nearby neighborhoods it tests the hypothesis that communities exposed to high levels of pollution will have lower house prices and poorer residents than cleaner locations the econometric model treats pollution and income as simultaneously determined variables the multiple equation fixed effects model attempts to account for cross section and time varying biases it uses toxics release inventory tri and census data from the 1980s for the six new england states i employ a new measure of the change in exposure to pollution over the 1980s for census tracts the estimates suggest that being a mile closer to a polluting manufacturing plant reduces house values by 1 9 which is smaller than estimates from existing studies however the equivalent single equation estimate suggests misleadingly that pollution has a positive effect on house values

credence attributes voluntary organizations and social pressure abstract credence attributes of products are unobservable through search or experience some consumers are willing to pay a premium for their provision and in addition citizens can apply social pressure on firms to supply credence attributes firms have formed voluntary organizations to assure the provision of credence attributes and the credible provision provides product differentiation this paper provides a theory of the voluntary provision of credence attributes in the presence of demand pull from consumers and social pressure from ngos where an organization chooses a credence standard and firms compete given the standard the credence standard is lower the larger the organization and social pressure results in a higher standard

biological and economic foundations of renewable resource exploitation abstract a physiologically based population dynamics model of a renewable resource is used as the basis to develop a model of human harvesting the model incorporates developing technology and the effects of market forces on the sustainability of common property resources the bases of the model are analogies between the economics of resource harvesting and allocation by firms and adapted organisms in nature specifically the paper makes the following points 1 it shows how economic and ecological theories may be unified 2 it punctuates the importance of time frame in the two systems evolutionary versus market 3 it shows contrary to prevailing economic wisdom how technological progress may be detrimental to resource preservation 4 it shows how the anticipated effects of high discount rates on resource use can be catastrophic when synergized by progress in harvesting technology 5 it suggests that increases in efficiency of utilization of the harvest encourages higher levels of resource exploitation and 6 it shows the effects of environmental degradation on consumer and resource dynamics the model leads to global implications on the relationship between economic growth and the ability of modern societies to maintain the environment at a sustainable level

a sealed bid auction mechanism for siting noxious facilities this paper proposes a sealed bid mechanism for facilitating the siting process of noxious facilities such as prisons trash disposal plants and incinerators for hazardous waste these facilities have created such opposition by communities that the acronyms nimby not in my backyard or lulu local undesirable land use are now in common usage to describe the public s reaction to them the noxious facility siting problem arises because there are economies of scale associated with having only one plant to serve the needs of a wide region the community that hosts the plant absorbs all of the environmental costs while the rest of the region enjoys the benefits of the facility one reason that these facilities have been so strongly opposed by communities is that they generate relatively little new employment and provide limited additional taxes in relation to their perceived negative impact d morell and c magorian 1982 some compensation arrangement is thus needed to share the gains from the winners to the potential loser this paper discusses a sealed bid auction mechanism for selecting a location for the facility so that all communities feel they are better off than under the status quo

geographies of energy transition space place and the low carbon economy this paper makes a case for examining energy transition as a geographical process involving the reconfiguration of current patterns and scales of economic and social activity the paper draws on a seminar series on the geographies of energy transition security climate governance hosted by the authors between 2009 and 2011 which initiated a dialogue between energy studies and the discipline of human geography focussing on the uk government s policy for a low carbon transition the paper provides a conceptual language with which to describe and assess the geographical implications of a transition towards low carbon energy six concepts are introduced and explained location landscape territoriality spatial differentiation scaling and spatial embeddedness examples illustrate how the geographies of a future low carbon economy are not yet determined and that a range of divergent and contending potential geographical futures are in play more attention to the spaces and places that transition to a low carbon economy will produce can help better understand what living in a low carbon economy will be like it also provides a way to help evaluate the choices and pathways available

using country balance sheet data to predict debt rescheduling in this study we utilise data relating to the balance sheets of developing countries e g short term debt in a logit model of debt rescheduling we find that such variables are theoretically and empirically superior to those conventionally used such as debt export ratios the study is based upon an annual sample of 27 countries for 1977 1981 and a six monthly data set involving 59 countries from 1977 1985

trade offs in energy and environmental policy abstract the energy sector is undeniably undergoing a critical period faced with multiple challenges whether economic political or technological these challenges are related to the requirements set on the sector to meet a wide range of social demands associated with the three traditional dimensions of a sustainable energy system i e environmental sustainability security of energy supply and economic sustainability in particular the environmental pillar has gained ground after the paris agreement which has reinforced the requirement of a low carbon transformation of the sector a main challenge is to balance trade offs among competing goals when designing energy and environmental policies although making the energy sector greener is a common aspiration of governments and many countries are indeed being successful in this regard the success comes at a price in terms of the other non environmental dimensions of a sustainable energy system the aim of this special issue is to look in detail on some of the most pressing environmental challenges faced by the energy sector as well as the trade offs involved in reaching a greener energy system

asymmetries in the valuation of risk and the siting of hazardous waste disposal facilities recently several economists richard thaler 1980 jack knetsch and j a sinden 1984 following suggestions of psychologists daniel kahneman and amos tversky 1979 have argued that current economic models of consumer behavior fail to explain observed asymmetries in how individuals respond to gain vs losses in perceived entitlements attention to their arguments is increasing because they relate to many current policy issues especially those associated with undesirable land uses most of the papers suggesting this limitation with the conventional economic framework have been motivated by the large differences between the estimates of willingness to pay vs willingness to accept as measures of the change in individual well being that would result from a change in the conditions of access to or the quality of a commodity in this paper we report the first evidence of a sizable property rights effect using only willingness to pay measures this change is potentially important because both the recent appraisal of contingent valuation surveys see ronald cummings et al 1986 an important source of the available empirical evidence and laboratory experiments suggest that individuals may have difficulty in dealing with the concept of compensation this is especially true when there is no opportunity for individuals to learn about transactions that involve compensation through experience based on a contingent valuation survey of households in suburban boston we found that respondents bid significantly more to reduce risk than they indicated they were willing to pay to avoid an equivalent risk increase while our findings support suggestions that changes in the implied entitlements to safety can lead to large differences in welfare measures for risk changes several of these earlier arguments would have implied that individuals were willing to pay more to avoid a risk increase the opposite to our results thus these differences imply that the determinants of individuals valuations for risk changes are more complex than past studies have acknowledged

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

predicting the quantity of ldc debt rescheduling in this paper we estimate a type 2 tobit model to explain both the timing and quantity of developing country debt rescheduling using an annual data set for 27 countries from 1977 1981 and six monthly data for 59 countries from 1977 1985 we obtain a satisfactory model for both the timing and quantity of rescheduling which will be more useful for country risk analysis than models which predict the timing alone

property rights protest and the siting of hazardous waste facilities ture since that time no major hwf has been sited anywhere in the united states the epa had anticipated that local opposition would make finding these sites an exceptionally difficult task their pessimism was well founded and if anything understated according to the hazardous waste counsultant s latest state by state review the outlook for siting hwfs in the future is even more bleak than in the past due in large part to what they term a worsening of the emotional atmosphere surrounding siting efforts this failure to site any new hwf has come about in spite of assurances by government and company officials that new facilities built according to the present standards would pose negligible risks to the local residents attempts have been made to break the deadlock by instituting extensive public participation procedures establishing state siting boards with the power to overrule local decision makers and requiring facility owners to compensate local governments for safety services the latter provided in this paper we argue that the ambiguous nature of the present property rights governing the siting of hwfs is an important cause of the stalemate we offer a new approach to siting which recognizes the de facto property rights assumed by local communities we propose a political market via a referendum

a consumption based theory of the environmental kuznets curve abstract most theories about the inverted u relationship between pollution and income termed the environmental kuznets curve ekc are production side theories emphasizing pollution and abatement technologies production side theories are implicitly based on the assumption of low factor mobility and the absence of pollution as a variable in the utility function both assumptions are called into question by the empirical evidence of ekcs for i pollutants that are long lived and not easily shiftable and ii regional cross sections with free labor mobility hazardous waste sites are a prime example this paper develops a stylized model of the ekc based on perfect mobility of households and labor it represents the first attempt at developing a consumption side model of the ekc

discounting in the presence of scarce ecosystem services abstract the discount rate for cost benefit analysis has to take account of future scarcity of ecosystem services in consumption and production previous literature focuses on the first aspect and shows the importance of the relative price effect for given growth rates of consumption and ecosystem services this paper focuses on intermediate ecosystem services in production and shows that for limited substitutability and a low growth rate of these ecosystem services the growth rate of consumption and thus the discount rate declines towards a low value using a ramsey growth model the paper distinguishes three cases if ecosystem services can be easily substituted the discount rate converges to the usual value in the long term secondly if ecosystem services can be easily substituted in production but not in consumption the relative price effect is important finally and most interestingly if ecosystem services cannot be easily substituted in production the discount rate declines towards a low value and the relative price effect is less important another part of the previous literature has shown that a declining discount rate is the result of introducing several forms of uncertainty but this paper reaches that conclusion from an endogenous effect on the growth rate of the economy

the dynamic study on firm s environmental behavior and influencing factors an adaptive agent based modeling approach employing an adaptive agent based modeling approach the present study explored the evolvement of firms environmental behavior and influencing factors using empirical data from 167 firms in china the simulation results revealed that firms environmental behavior followed this evolvement path defensive behavior preventive behavior and enthusiastic behavior computational experiments indicated that with increased financial ability and level of environmental preparedness the number of firms in all three categories of environmental behavior increased and so did their profits with increased public pressure the number of firms with defensive environmental behavior and their profits decreased but the number of firms with preventive and enthusiastic environmental behavior and their profits increased on the other hand when managers education level increased the number of firms with defensive behavior deceased but their profits increased slightly though the number of firms with preventive and enthusiastic behavior and their profits increased sharply in addition with the increased regulation level the number of firms with a different category of environmental behavior and their profits decreased finally with increased financial subsidy and market share the number of firms with different behavior and their profits were modified slightly

the influence of financial status on the effectiveness of environmental enforcement abstract this paper analyzes the influence of financial status on the effectiveness of environmental enforcement it considers multiple dimensions of both enforcement and financial status regarding enforcement the paper considers both the likelihood of enforcement as captured by the likelihood of inspections conducted at regulated facilities and the severity of enforcement as captured by the size of sanctions imposed on polluting facilities found violating their effluent limits as indicators of corporate financial status the paper considers measures of liquidity solvency and profitability a proxy for corporate managerial skill all of which can influence the likelihood that a firm faces liquidity and or bankruptcy constraints the paper first develops a theoretical model of optimal abatement in the presence of liquidity and bankruptcy constraints and uses the model to investigate the impact of financial status on optimal abatement and the effectiveness of enforcement then the paper empirically examines the interactions between enforcement and financial status using data on wastewater discharges from us chemical manufacturing facilities for the years 1995 to 2001 empirical results suggest that the financial status dimensions considered here in general play an important role in determining the incentives created by enforcement as the most striking result we show theoretically and empirically that when financial dimensions are included in the analysis the conventional wisdom regarding the effect of enforcement likelihood on abatement no longer holds i e increased enforcement can actually lead to worse environmental performance

power distribution the environment and public health a state level analysis abstract this paper examines relationships among power distribution the environment and public health by means of a cross sectional analysis of the 50 us states a measure of inter state variations in power distribution is derived from data on voter participation tax fairness medicaid access and educational attainment we develop and estimate a recursive model linking the distribution of power to environmental policy environmental stress and public health the results support the hypothesis that greater power inequality leads to weaker environmental policies which in turn lead to greater environmental degradation and to adverse public health outcomes

causes of u s farm commodity programs this paper i s an attempt to explain variations by commodity in producer protection afforded by farm price support programs since the1930s particularly emphasized are theideas that these programs are essentially income redistributional measures and that given political forces the programs are attempts to redistribute efficiently variables associated with the cost to producers of generating political pressure and the social cost deadweight losses of redistribution are both found to be empirically important copyright 1987 by university of chicago press

on the environmental discount rate abstract in this paper i show that environmentalism itself can provide a rigorous foundation for the low and declining discount rates that environmentalists seem to favor in long term cost benefit calculations if indeed it is a stylized fact that we are moving toward a world where environmental spending is increasingly important that scenario per se may significantly lower the social rate of return a formula is derived for the ratio of social to private discount rates as a simple function of two operational environmental parameters the formula is used to explain why the social rate of return ought to be lower than the private rate and why this gap called environmental drag when measured in terms of equivalent evaporation of national income may be expected to increase over time

optimal pricing of environmental and natural resource use with stock externalities abstract underlying some of the most pressing environmental problems are the interlinked resource and environmental stock externalities with threshold effects using a simple dynamic model it is shown how in the face of such externalities the static market based policy instruments such as pigouvian taxes should be modified it is shown that even if for an initial period there is going to be no pollution stock damage the optimal policy still requires that abatement begins immediately and at increasing rates simulation of the model for the case of fossil fuel burning and the consequent global warming shows that the optimal carbon tax and therefore the optimal control strategy is particularly sensitive to changes in the marginal abatement cost and the level of fossil fuel demand policy simulations contrast the optimal control policy with and estimate the welfare losses from alternative policies deriving from arbitrary tax paths the latter include i a no tax policy ii a constant carbon tax rate iii the european community s proposed carbon tax path and iv a delayed optimal tax path

learning abatement costs on the dynamics of the optimal regulation of experience goods we study the introduction of new technologies when their costs are subject to idiosyncratic uncertainty and can only be fully learned through individual experience we set up a dynamic model of clean experience goods that replace old polluting consumption options and show how optimal regulation evolves over time in our base setting where social and private learning incentives coincide the optimal tax on the polluting consumption is increasing over time we show however that if social and private learning incentives diverge because the private discount rate exceeds the social discount rate it may be optimal to temporarily increase the tax rate beyond net marginal external damages to induce more learning before reducing the tax rate to the steady state level alternatively one could complement the tax with subsidies for first time users which can be phased out over time similar results apply if consumers have biased expectations we therefore give a rationale for introductory subsidies on new clean technologies and non monotonic tax paths from a perspective of consumer learning

why do firms engage in environmental management an empirical study in china abstract there are increasing pressures being put on firms from a number of different sources such as governmental regulation community participation and market demand to engage firms in environmental initiatives these factors play different roles at various development periods government regulation was the major pressure initially however community participation and market demand have become more and more important thus a better understanding of the determinant factors that play a role in engaging firms to take environmental management initiatives may help policy makers develop more effective environmental policies using data collected from 89 firms in wujin county of jiangsu province china this paper developed an index system to evaluate the corporate environmental management performance furthermore we used econometric methodology to identify the main factors that probably shape corporate environmental management performance including both external pressures and firm characteristics the results showed that pressures from supply chain customers and communities played positive roles in engaging firms to improve environmental management performance however the pressure from the regulatory system did not implicate positive effect on environmental management performance when basic compliance is not an issue in the region anymore the results also showed that firms with larger scale will be more active in engaging in environmental management initiatives finally our results suggest that a regulation s stimulation may be reduced as long as firms have complied with requirements of local environmental standards and other environmental laws b policy makers should pay more attention to market and information instruments c more financial and technical support should be provided to encourage small and medium sized enterprises smes to improve environmental performance

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

income environmental disamenity and toxic releases the literature argues that income growth leads to increased demand for environmental quality and thus reduction in pollution using a utility theoretic model we hypothesize that the income pollution relationship should depend on the level of disamenity of the pollutant we proxy for disamenity using the toxicity of releases for counties in the united states the functional relationship between income and releases depends on the level of disamenity the form is more concave for more toxic releases we find that environmental improvements occur at lower levels of per capita income for more toxic pollutants jel q25 q28 o13

internal migration and the environmental kuznets curve for us hazardous waste sites abstract in the recent special issue of ecological economics devoted to the environmental kuznets curve ekc hypothesis rothman speculates that what appear to be improvements in environmental quality may in reality be indicators of increased ability of consumers in wealthy nations to distance themselves from the environmental degradation associated with their consumption rothman d 1998 environmental kuznets curves real progress or passing the buck a case for consumption based approaches ecol econ 25 178 consistent with rothman s general hypothesis of distancing as a possible source of ekc results this empirical study advances and tests a line of argument in which internal migration plays a central explanatory role for an observed ekc for us hazardous waste sites two specific hypotheses tested are i proximity to hazardous waste site build up emerges as a factor in the migration decisions of individuals as per capita income increases beyond a threshold level and ii the level of income at which the ekc turns downwards is equal to the threshold level of income in i results provide evidence that migration is a contributing factor to the observed ekc

polluters and collective action theory and evidence 1 introductionthe seminal theory by olson 1965 predicts that industries with fewer firms have a greater ability to undertake collective action they organize cooperative political action more easily because greater concentration lowers the cost of political action 1 the empirical evidence is inconclusive however andres 1985 masters and keim 1985 heywood 1988 and humphries 1991 find positive effects of industry concentration on the probability of making political action committee pac contributions see also mckeown 1994 pittman 1976 finds that concentrated industries generate greater contribution levels grier munger and roberts 1991 find an inverted u shaped relationship between the level of pac formation and industry concentration with a maximum political participation rate occurring at a four firm concentration ratio around 0 45 esty and caves 1983 and zardkoohi 1985 report ambiguous effects of concentration on pac contributions 2in this paper we suggest an alternative perspective on firms ability to organize collective action which to our knowledge has been ignored so far the novel argument is that industries that face multiple regulations a greater number of policy issues find it easier to overcome collective action problems and sustain lobbying in particular we focus on the difference between firms in polluting and clean industry sectors using a simple repeated game framework similar to spagnolo 2000 we argue that firms in industries that are naturally polluting because of their input requirements and therefore incur pollution abatement costs will face an additional policy battle compared with other industries everything else equal 3 this enables such industries to sustain greater cooperation and lobbying this is because firms seeking to form a lobby group face a free riding problem due to a limited amount of enforcement power available to punish deviation and ensure cooperation firms that face multiple areas of regulation have an advantage in the formation of lobby groups because they have a greater amount of enforcement power available to reallocate between policy issues when joint lobbying gives large gains in environmental policy this surplus can be reallocated to trade policy for example free riding behavior on trade policy lobbying may more easily be disciplined the prediction that emerges from our theoretical model is that polluting industries are relatively less affected by the free riding problems involved in organizing political action and we thus expect the level of political contributions to be higher in these sectors 4we evaluate this prediction using a cross section data set of u s manufacturing industries our empirical model builds on a multiple equation model by gawande and bandyopadhyay 2000 who test the well established theory of grossman and helpman 1994 on the pattern of protection their theory takes lobby group formation as given we augment gawande and bandyopadhyay s model with an additional equation for environmental policy stringency 5 the empirical results lend support to our theory industry pac contributions and thus the level of lobby group cooperation are greater in industries with larger pollution abatement costs this result is robust to several measures of lobby group formation and environmental policy the present paper contributes to the recent literature on the formation of lobby groups in the area of pollution taxation damania and fredriksson 2000 argue that collusive industries may more easily form lobby groups that oppose such taxes using a related setup damania and fredriksson 2003 discuss the effect of exogenous trade liberalization on environmental policy formation when lobby group formation is endogenous pecorino 1998 and mitra 1999 discuss the formation of trade lobby groups 6 neither of these papers explore the relationship between collective action and the number of policy instruments however

co2 content of electricity losses abstract countries are implementing policies to develop greener energy markets worldwide in europe the 2030 energy and climate package asks for further reductions of green house gases renewable sources integration and energy efficiency targets but the polluting intensity of electricity may be different in average than when considering market inefficiencies in particular losses and therefore the implemented policy must take those differences into account precisely herein we study the importance in terms of co2 emissions the extra amount of energy necessary to cover losses with this purpose we use spanish market and system data with hourly frequency from 2011 to 2013 our results show that indeed electricity losses significantly explain co2 emissions with a higher co2 emissions rate when covering losses than the average rate of the system additionally we find that the market closing technologies used to cover losses have a positive and significant impact on co2 emissions when polluting technologies coal or combined cycle close the market the impact of losses on co2 emissions is high compared to the rest of technologies combined heat and power renewables or hydropower to the light of these results we make some policy recommendations to reduce the impact of losses on co2 emissions

bridging the trade environment divide protection for free traders this word represents the consummate evil for environmentalists it is the ultimate good of course for the trade community protection conjures up dark images of smoot and hawley while the environmental camp sees clear mountain streams lush green forests and piercing blue skies one cannot blame all of the tensions at the trade environment interface on linguistic differences but these competing perspectives are emblematic of a deep clash of cultures theories and assumptions trade officials often seek to limit efforts to link trade and environmental policy making and sometimes to prohibit such efforts altogether in this regard the narrow focus and modest efforts of the world trade organization s committee on trade and environment are illustrative 1 the launch of negotiations for a free trade area of the americas with an express decision to exclude environmental issues from the agenda provides an even starker example of the trade community s hostility toward serious environmental engagement economists have been prominent among those arguing that pollution control and natural resource management issues are best kept out of the trade policy making process cooper 1994 bhagwati 1999 other economists however have tried to set trade policy making in a broader context and to build environmental sensitivity into the international trading system runge 1994 rodrik 1997 summers 2000

simple rules for climate policy and integrated assessment a simple integrated assessment framework that gives rules for the optimal carbon price transition to the carbon free era and stranded carbon assets is presented which highlights the ethical economic geophysical and political drivers of optimal climate policy for the ethics we discuss the role of intergenerational inequality aversion and the discount rate where we show the importance of lower discount rates for appraisal of longer run benefit and of policy makers using lower discount rates than private agents the economics depends on the costs and rates of technical progress in production of fossil fuel its substitute renewable energies and sequestration the geophysics depends on the permanent and transient components of atmospheric carbon and the relatively fast temperature response and we allow for positive feedbacks the politics stems from international free rider problems in absence of a global climate deal we show how results change if different assumptions are made about each of the drivers of climate policy our main objective is to offer an easy back on the envelope analysis which can be used for teaching and communication with policy makers

early warning of debt rescheduling abstract this study addresses the early warning of debt rescheduling by developing countries the early warning capability of different statistical methods is compared by using the same data base i e 52 countries from 1974 to 1978 the results especially show that cluster analysis techniques don t do well and that multiple discriminant analysis is inferior to logit analysis the integration of qualitative and projected data is proposed in order to arrive at bank specific systems

a theory of competition among pressure groups for political influence this paper presents a theory of competition among pressure groups for political influence political equilibrium depends on the efficiency of each group in producing pressure the effect of additional pressure on their influence the number of persons in different groups and the deadweight cost of taxes and subsidies an increase in deadweight costs discourages pressure by subsidized groups and encourages pressure by taxpayers this analysis unifies the view that governments correct market failures with the view that they favor the politically powerful both are produced by the competition for political favors

investigating external and internal pressures on corporate environmental behavior in papermaking enterprises of china abstract as china s ecological environmental problem becomes severe corporate environmental behavior ceb has become the focus of a range of stakeholders policy makers and the whole society since the operating activities of companies is the main source of environmental pollution this study used a questionnaire survey and structural equation model sem to examine the relative importance of external and internal pressures eip on driving ceb data was obtained from 702 papermaking companies in china the mechanism of eip effects on ceb was tested employing sem through path analysis using amos 21 0 the results showed that government pressure economic pressure and internal pressure played significant positive roles in environmental behavior of papermaking companies in china economic pressure was the most important factor on environmental behaviors including defensive accommodative and proactive behaviors of papermaking companies furthermore the role of internal pressure on ceb defensive and proactive was second only to economic pressure while the role of government pressure on ceb was much weaker than our expectation however the role of social pressure which was imposed by general public and environmental non governmental organizations ngos was not significant thus policy makers should emphasize on the interactions of economic mechanism government regulation and internal incentive mechanism to stimulate firms to adopt active environmental behavior more concerns from the general public shall be addressed to enhance their driving effect on ceb in chinese papermaking industry

are risk regulators rational evidence from hazardous waste cleanup decisions a large literature in economics and social science focuses on how people reason about risks reactions of individuals to risk frequently depart from behavior predicted by full information variants of expected utility theory risk regulators are human and are subject to political pressures that are reflective of people s attitudes toward risk as a result the public policies they espouse may reflect errors in judgment about risk many biases stem from misperceptions of risk individuals overestimate small probabilities overestimate the risks associated with highly publicized dangers and have preferences over the manner not just the magnitude in which risks arise environmental risks associated with hazardous waste sites may be particularly prone to such errors since they involve small risks that are highly publicized indeed the general public ranks hazardous waste sites as the leading environmental risk a growing literature also analyzes how the decisions of risk regulators depart from choices predicted in a standard benefit cost framework as roger g noll and james e krier 1990 point out since regulators are both human and political their decisions may reflect risk biases regulators may exhibit these biases as individuals and because their constituents will express regulatory demands based on risk perceptions risk regulators may take into account the identity of the parties exposed to risk the level of scrutiny by interest groups the nature of congressional representation of affected constituents and the degree of political activity by potentially exposed individuals 3 errors in risk perceptions and risk decisions cause individuals to diverge from expected utility maximization similar errors by policy makers and the influence of risk politics cause regulators to diverge from social welfare maximization this paper examines decisions made by federal and state regulators at hazardous waste sites addressed by the superfund program to determine how their decisions diverge from those predicted by expected utility theory and benefitcost analysis we analyze whether risk perceptions and politics influence two decisions central to the how clean is clean debate at superfund sites the selection of chemical cleanup targets and the expenditure of remediation funds at these contaminated sites we also explore the interactive influence of risk perception factors and political demands previous research on the regulation of chemical risks in standard setting indicates that decisions reflect evidence of risk biases and responsiveness to political factors in assessing the determinants of the epa s decision to cancel pesticide registration maureen l cropper et al 1992 found that the epa was more likely to cancel a pesticide in instances featuring higher risks to the maximally exposed individual user lower benefits associated with continued use of the pesticide higher values of intervention by environmental groups mea viscusi harvard law school harvard university cambridge ma 02138 hamilton sanford institute of public policy duke university durham nc 27708 we have benefited from the comments from two referees and the excellent research assistance of jason bell kristen blann jahn hakes and robert malme research support was provided under cooperative agreement no cr 823604 01 from the u s environmental protection agency office of policy planning and evaluation dr alan carlin and dr suzanne giannini spohn served as contract officers all views and errors expressed are our own l see u s environmental protection agency epa 1987 for a report on this survey evidence 2 this theme is also articulated in richard j zeckhauser and viscusi 1990 noll 1989 provides a more general assessment of the interaction between political concerns and regulatory policy which is a central theme of this paper 3political factors have long played a prominent role in local hazardous waste policies see among others linda cohen 1981 howard kunreuther and douglas easterling 1990 1992 and kunreuther and rajeev gowda 1990

an adjustment restriction on fish quota resource rents overcapacity and recovery of fish stock management objectives of the european union for north sea fish stocks are shifting towards considering both biological sustainability and economic benefits as part of multiannual management plans an adjustment restriction on fish quota has been introduced its objective is to obtain an efficient fish stock and to reduce overcapacity for the fishing industry we develop and apply a bi level stochastic dynamic programming model to study the effect of a quota adjustment restriction on the net present value of resource rents overcapacity and fish stock when the system is recovering from a downward environmental shock at level one a policy maker sets the quota considering fishermen behavior stochastic fish stock dynamics capital stock dynamics and a quota adjustment restriction at level two fishermen harvest myopically and make long term investment decisions assuming that fish stock and quota do not change over time the two levels are linked by the quota which is optimized by the policy maker at level one and becomes a restriction for myopic harvest and long term investment decisions of fishermen at level two our analysis suggests that in the long run overcapacity can be reduced by 54 at modest costs namely at a 1 reduction in the net present value of resource rents long and short run sustainability of the fish stock is not affected

politics and social costs estimating the impact of collective action on hazardous waste facilities firms that generate negative externalities may consider the effects of their location on the surrounding environment because of the right of their prospective neighbors to demand compensation for pollution and raise the transaction costs of location since communities vary both in the value individuals place on the environment and in the ability of residents to organize politically locations that generate the least political opposition may not be the locations that result in the lowest externalities this article tests whether the degree to which firms internalize their externalities depends on the ability of affected communities to engage in collective action the results indicate that firms processing hazardous waste when deciding where to expand capacity do take into account variations in the potential for collective action to raise their costs

country balance sheet data vs traditional macro variables in a logit model to predict debt rescheduling abstract this paper presents empirical estimates of rescheduling probabilities for 68 debtor countries using semi annual data from 1981 i through 1988 ii the set of regressors integrates bis data on banks balance sheet positions e g the ratio of short term debt to total debt of developing countries or undisbursed credit commitments to total debt with traditional macro variables e g export growth or gross domestic product of the g7 all estimated equations have a high explanatory power the novel result is that as the prediction lag is lengthened the significance of the macro variables improves relative to the one of the balance sheet data this suggests that macro variables are proxies for more fundamental longer term determinants of a country s solvency whilst financial variables provide information about the country s current liquidity

relief for the environment the importance of an increasingly unimportant industrial sector deindustrialization stagnant real incomes of production workers and increasing inequality are latter day features of many economies it is common to assume that such developments pressure policymakers to relax environmental standards however when heavily polluting industries become less important economically their political importance also tends to diminish consequently a regulator may increase the stringency of environmental policies like some other studies we find that declining industrial employment translates into stricter environmental standards in contrast to previous studies but consistent with our argument we find that greater income inequality is associated with policies that promote a cleaner environment jel q58 p16 j31 c23
