the environmental kuznets curve environmental protection policy and income distribution abstract the effect of economic growth on pollution emissions differs substantially among high income countries i address this issue by analyzing public environmental policy decisions individual heterogeneity relative income effect and the political framework in which policy decisions are taken determine the emergence of the downward sloping segment of the environmental kuznets curve ekc income inequality produces a gap between the country s ability to pay for environmental protection and a country s willingness to pay i test this result by using oecd data on public r d expenditure for environmental protection the conclusion is that contrary to the ek hypothesis moments of the income distribution function other than the mean may be important for the emergence of a virtuous path of sustainable growth in high income countries

energy market liberalization and renewable energy policies in oecd countries abstract this paper investigates the effect of energy liberalization compared to other drivers on policies that support renewable energy in a long panel of oecd countries we estimate this effect by accounting for the endogeneity of liberalization related to joint decisions within a country s energy strategy using regulation in other industries as instruments we find that energy liberalization increases public support for renewable energy the effect of liberalization is the second largest after the effect of per capita income and is mostly driven by reductions in entry barriers while the effect of privatization is unclear this finding suggests that a reduction in the monopolistic power of state owned utilities has a positive effect on renewable energy policies when various types of actors are ensured access to the grid instead of it being provided to only a few large private firms

the solution to the tullock rent seeking game when r 2 mixed strategy equilibria and mean dissipation rates in tullock s rent seeking model the probability a player wins the game depends on expenditures raised to the power r we show that a symmetric mixed strategy nash equilibrium exists when r 2 and that overdissipation of rents does not arise in any nash equilibrium we derive a tight lower bound on the level of rent dissipation that arises in a symmetric equilibrium when the strategy space is discrete and show that full rent dissipation occurs when the strategy space is continuous our results are shown to be consistent with recent experimental evidence on the dissipation of rents

structural change and income distribution an inverted u relationship abstract this paper constructs a disequilibrium model in order to analyse the structural transition characterized by the emergence of a new sector we show that in an economy where preferences and technology adapt over time multiple long term outcomes are mainly brought about by different distributive rules governing the assignment of innovative rents between workers and entrepreneurs we robustly establish that a successful transition to a two sector economy is ensured by a balanced distribution restoring the co ordination of investment and consumption plans instead when innovative rents are too concentrated in favor of either workers or entrepreneurs the system does not fully accomplish the transition and unemployment might emerge in contrast with the standard view of a negative relationship between real wages and employment

using weather index insurance to improve drought response for famine prevention there is a strong link between weather and the welfare of poor populations low frequency short term but catastrophic weather shocks can trigger destructive coping responses to disaster for example withdrawal of children from school distress sale of assets refugee migration crime and severe human suffering moreover these adverse impacts often persist as children s physical growth falters and household productivity asset accumulation and income growth are dampened dercon and krishnan 2000 hoddinott and kinsey 2001 hoddinott 2006 the prospect of such shocks may also induce underinvestment in assets at risk limiting poor households ability to grow their way out of poverty over time carter and barrett 2006 the problem originates with the difficulty poor households face in insuring covariate risk while informal social insurance arrangements and flexible credit contracts often

structural changes and sustainability a selected review of the empirical evidence abstract the paper offers a review of selected topics in the empirical literature on structural change and sustainability we focus on aspects of structural change that directly affect emissions and energy intensity changes of the sectoral composition of economies trade and international fragmentation of production technological change and innovation and demand we identify several empirical facts first only a few countries have experienced a decoupling between growth and emissions due to proportionately faster growth rather than greater energy efficiency second the long term shift from manufacturing to services has not led in all cases to the de materialisation of economies and a lower environmental burden exploitation of energy efficiency increases depends on the ability of the service sectors to incorporate technical changes to reduce energy intensity third global trade and energy and emissions intensity trends support the pollution haven hypothesis which predicts displacement of the environmental burden from developed to emerging countries the pursuit by developing countries of a long term strategy of trading jobs for emissions is likely to exacerbate the asymmetry related to emissions intensities between developed and less developed economies the review should inform debate on environmental policy within the broader context of innovation and development policies

fossil resource trade balances emerging trends for the uk abstract the aim of this paper is to examine the extent to which the uk can be classified as a net importer of fossil resources and a creator of pollution havens abroad between 1968 and 2000 using input output techniques and a derived resource flow classification system both the physical trade balance ptb and pollution trade balance utb associated with fossil resource use are computed the ptb shows that between 1968 and the early 1980 s the uk is presented as a net importer of direct fossil resource flows between 1984 and 2000 the uk is identified as a net exporter of direct fossil resources these trends are primarily explained by the uk s discovery and commercial production of north sea oil and gas fields in the late 1970s on the other hand the utb shows that over the whole period the indirect used flows attributable to the uk s exports are higher than those attributable to its imports these findings suggest that the uk did not create pollution havens abroad from the use of fossil resources between 1968 and 2000 however it is noticeable in both cases that from 1995 the uk s position as a net exporter has been decreasing considerably maturing north sea oil and gas fields set against increasing demands for fossil fuels and imported goods is signalling a return to the uk s pre 1984 dependence on direct imported fossil resources and the possible creation of pollution havens abroad knowledge of these trends contributes to the evidence base for the uk s changing import and export structure and the potential environmental repercussions at home and abroad

do individual preferences explain the environmental kuznets curve abstract some economists maintain the optimistic view that individual preferences of rich people eventually lead to a virtuous circle relationship between rising income and environmental degradation in this article i review some of the models that establish a relationship between individual preferences and environmental quality these models provide a basis for discussion of the key role played by two factors individual preferences and technology they do not however capture the distributive conflicts that occur between different social groups in the process of defining environmental policy neither do they provide a good basis for distinguishing between environmental costs caused by the decisions of particular consumers and those which affect the same consumers this point is related to the various manners in which environmental costs are displaced displacement often occurs within a country for current costs and is even clearer and more relevant when costs are transferred across a great distance or to a remote future in such cases there are few incentives to reduce consumption or alter its composition displacement moreover can become a strategy pursued more or less consciously for maintaining high and rising levels of consumption without dealing with the associated environmental costs

statistical measures of unsustainability abstract statistical measures are needed to reveal at a glance how far or near various countries are to meeting the conditions of long run sustainability and how conditions are changing on a year to year basis i e whether sustainability is being approached or not the scheme proposed in this paper presents numerical comparisons of energy and materials use in the real world vis a vis an ideal case where all of the identifiable criteria for sustainability are satisfied apart from population stabilization five general but quantifiable criteria for sustainability are suggested including 1 stabilization of greenhouse gas concentrations in the atmosphere 2 stabilization of acidity ph in rainfall 3 reduction of dissipative uses and wastes of heavy metals to natural mobilization rates or lower 4 elimination of agriculture based on pumping fossil water from non renewable aquifers and 5 elimination of loss of arable land because of salination or erosion other criteria such as preservation of biodiversity and socio economic equity between countries and generations might be added to the list they introduce more difficult measurement problems however which are not considered further in the paper having fixed the list of criteria the next step is to identify measures that either go to zero or unity as the system approaches more and more closely to sustainability at least in the limited sense defined above various types of measures of sustainability unsustainability can be developed viz i measures of relative dependence of the economy on non renewable sources of energy and materials ii measures of the productivity of energy and materials consumed by the economic system and iii measures of dissipative loss especially of toxic and hazardous substances specific examples of each type are discussed

the impacts of petroleum price fluctuations on income distribution across ethnic groups in malaysia crude oil price hikes have compelled governments of developing countries to let domestic prices of energy increase fiscal priorities made it impossible to fully compensate the hikes by raising energy subsidies this paper examines the potential impacts of a limited deregulation of the petroleum price on the income distribution in malaysia paying specific attention to differences in impacts on major ethnic groups we introduce an extended social accounting matrix sam model which not only incorporates substitution possibilities among production inputs and consumption goods but also allows for the exogenous determination of the price of intermediate inputs the results of simulations indicate that distributional impacts of rising petroleum prices tend to be regressive affecting poor people more severely than richer people all ethnic groups experience income loss with the real incomes of malay households which are relatively poor on average more than the chinese and indian households which are the generally richer

who should abate carbon emission we review the optimal pattern of carbon emission abatements across countries in a simple multi country world we model explicitly with the model in chichilnisky 4 the fact that the atmosphere is a public good within this framework we establish conditions for it to be necessary for optimality that the marginal cost of abatement be the same in all countries these condition are quite restrictive and amount to either ignoring distributional issues between countries or operating within a framework within which lump sum transfers can be made between countries these results have implications for the use of tradeable emission permits which as normally advocated will lead to the equalization of marginal abatement costs across countries the observation that the atmosphere is a public good implies that we may need to look at a lindahl equilibrium rather than a walrasian equilibrium in tradeable permits

environmental kuznets curves real progress or passing the buck abstract recent research has examined the hypothesis of an environmental kuznets curve ekc the notion that environmental impact increases in the early stages of development followed by declines in the later stages these studies have focused on the relationship between per capita income and a variety of environmental indicators results imply that ekcs may exist for a number of cases however the measures of environmental impact used generally focus on production processes and reflect environmental impacts that are local in nature and for which abatement is relatively inexpensive in terms of monetary costs and or lifestyle changes significantly more consumption based measures such co2 emissions and municipal waste for which impacts are relatively easy to externalize or costly to control show no tendency to decline with increasing per capita income by considering consumption and trade patterns the author re examines the concept of the ekc and proposes the use of alternative consumption based measures of environmental impact the author 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

income inequality and the environment aggregation bias in environmental kuznets curves abstract the environmental kuznets curve assumes an inverted u shaped relation between environmental damage and per capita income recently it has been argued in the literature that in addition to income levels the inequality in the distribution of power and income is positively related to environmental degradation we provide an additional argument based on simple aggregation for including a measure of income dispersion in empirical analyses when the relationship between environmental damage and household income is concave e g resembles an environmental kuznets curve then income inequality is negatively related to total environmental damage results from an empirical analysis of cross national variation indicate that the aggregation effect can run counter to and outweigh the political economy effect for some environmental indicators

political and economic inequality and the environment abstract this paper analyzes and tests the hypothesis that political and economic equality result in lower levels of environmental degradation based on formal statements of the argument put forward by boyce r 1994 ecological economics 11 169 178 i show that equality may or may not be necessary to minimize degradation under some plausible conditions greater inequality may even be conducive to lower degradation actual results depend primarily on the intersection between the distribution of preferences across groups and the institutional rules two cross national empirical tests tend to support the contention that distributional issues do not systematically explain variations in environmental quality the results reinforce the conclusion that assumptions about the structure of preferences and workings of social choice institutions ignore complex interactions which influence the relationship between degradation and equality

trade environment and development the issues in perspective abstract this special issue on trade and the environment brings together a number of papers that are constructively critical of the conventional economic wisdom on the topic we think that this criticism is warranted because of the decidely uncritical way in which free trade has been advocated in much of the literature and especially in policy the papers analyse the validity of the underlying assumptions on which the conventional wisdom is based and provide suggestions for ways to facilitate trade that is also adequately protective of the environment sustainability and other social values in this introductory piece we discuss trade the environment and sustainability summarizing arguments in the papers included in this issue and adding a few additional points not covered by them

energy burden alleviation and greenhouse gas emissions reduction can we reach two objectives with one policy in this article we assess french current public policies designed to reduce greenhouse gas ghg emissions and abate household energy burden through a simulation of changes in residential sector characteristics over the long run we build on an existing partial equilibrium model to take into consideration key determinants of excessive energy burden among vulnerable households this analysis reveals that current public policies are not sufficient to reach the ambitious objectives for reducing energy consumption and ghg emissions in france moreover the decreases that might occur mask significant social disparities across households the joint implementation of multiple instruments leads to interactions that diminish overall policy outcomes overall current public policies produce estimated free riding rates of 75 energy efficiency measures are thus insufficient in themselves the government should focus more on monetary poverty as a cause of low home improvement rates and consider subsidizing renovation costs as a potential solution

dissipation of contestable rents by small numbers of contenders the theory of rent seeking with its origins in the observations of gordon tullock 1967 or to use jagdish bhagwati s 1982 proposed term the theory of directly unproductive profit seeking activities is concerned with the potentially adverse effects on resource allocation of incentives to cap ture and defend artificially contrived rents and transfers the scope for so cial loss proposed by the theory derives from the relation between the value of a contestable prize and the value of the resources attracted into the con test to determine the beneficiary of the prize underlying this social loss is a specification of how rational behavior by optimizing agents links the value of the prize sought to the resources expended it has been traditional to assume competitive behavior in describing the activities of lobbying and influence seeking then if some further condi tions are satisfied l the total value of the resources expended precisely equals the value of the prize sought so dissipation is complete 2 conse quently the social cost associated with contestability of a rent can be in ferred from the value of the rent itself and the detailed and hard to come by information on individual outlays made in the course of the contest be comes unnecessary by basing their analyses on competitive dissipation contributors to the rent seeking literature see the review by robert tollison 1982 have been able to presume that the observed value of a contested rent is an exact measure of the associated social cost of monopoly power or regu lation similarly in the trade theoretic literature where the rights contested are to quota premia or revenues from trade taxes krueger 1974 bhagwati

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

developments in the throughput income relationship theoretical and empirical observations abstract it has been suggested that the relationship between income and the associated environmental pressure in terms of derived materials inputs and pollution levels may take an inverted u shape indicating a delinking of environmental pressure from economic growth in relation to rising per capita incomes the likelihood of such a relationship being persistent is discussed in the context of a simple macro model of industrial metabolism and the possibility of relinking clearly emerges data on specific indicators of environmental pressure i e the throughput of materials energy and the volume of transport in 19 countries have been used to investigate patterns of delinking the results suggest that delinking may not be persistent already some advanced economies may be entering a new period of relinking the relationships between environmental pressure and welfare in the medium long term may be n shaped rather than inverted u shaped

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

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

tailored to the extremes quantile regression for index based insurance contract design a new approach for weather index based insurance design based on quantile regression qr to condition the yield index dependency is developed and compared to standard regression technique three conceptual different risk measures i e expected utility expected shortfall and a spectral risk measure are used to evaluate the risk reducing properties of these contracts our findings show that qr is much more powerful in establishing the yield index dependency and lead for all risk measures to a higher risk reduction than the standard technique ordinary least squares ols thus qr leads to a more efficient contract design which is beneficial for both the insurer smaller remaining risk and the insured higher demand and willingness to pay our empirical application is based on a 31 years long time series of wheat yield data from northern kazakhstan

lead markets and regulation a framework for analyzing the international diffusion of environmental innovations abstract environmental regulations are often intended to stimulate the generation and adoption of eco efficient innovations an important argument in the public debate is also the creation of new markets for environmentally benign products processes and services in other countries and the generation as a result of export opportunities for the pioneering country lead markets research on lead markets has not however focused on environmental innovations to date we therefore extend the lead market model to environmental innovations and take particular account of the peculiarities of such innovations in particular the public good character of environmental benefits and the role of regulations this approach is applied to two case studies wind energy and fuel efficient passenger cars in both cases the innovation was initially adopted in one country other countries subsequently adopted the same innovation design favored by the lead market which in turn developed into a large exporter in the wind generation and car industries respectively we discuss the regulations employed and the reasons for the international success of the innovations induced by them our findings demonstrate that when supported by global demand or regulatory trends strict regulation results in the creation of lead markets finally we provide recommendations on how our model could be used for further research and in the development of a coordinated environmental and innovation policy

inequality as a cause of environmental degradation abstract this paper advances two hypotheses first the extent of an environmentally degrading economic activity is a function of the balance of power between the winners who derive net benefits from the activity and the losers who bear net costs second greater inequalities of power and wealth lead all else equal to more environmental degradation

economic growth and environmental degradation the environmental kuznets curve and sustainable development abstract in this paper we critically examine the concept of the environmental kuznets curve ekc it proposes that there is an inverted u shape relation between environmental degradation and income per capita so that eventually growth reduces the environmental impact of economic activity the concept is dependent on a model of the economy in which there is no feedback from the quality of the environment to production possibilities and in which trade has a neutral effect on environmental degradation the actual violation of these assumptions gives rise to fundamental problems in estimating the parameters of an ekc the paper identifies other econometric problems with estimates of the ekc and reviews a number of empirical studies the inference from some such ekc estimates that further development will reduce environmental degradation is dependent on the assumption that world per capita income is normally distributed when in fact median income is far below mean income we carry out simulations combining ekc estimates from the literature with world bank forecasts for economic growth for individual countries aggregating over countries to derive the global impact within the horizon of the bank s forecast 2025 global emissions of so 2 continue to increase forest loss stabilizes before the end of the period but tropical deforestation continues at a constant rate throughout the period

the determinants of atmospheric so2 concentrations reconsidering the environmental kuznets curve this analysis explores the effects of income and the spatial intensity of economic activity on the atmospheric concentration of sulfur dioxide the results indicate that there is a u shaped relation between income and atmospheric concentration of so2 and an inverted u shaped relation between the spatial intensity of economic activity and so2 concentrations these results suggest that the spatial intensity of economic activity rather than income provides the impetus for policies and technologies that reduce so2 emissions based on this result the atmospheric concentration of so2 in developing nations may decline faster than indicated by previous analyses the potential for this decline depends on the rate at which income grows relative to population the trade off between the effects of income gains and the spatial intensity of economic activity on the atmospheric concentration of so2 is consistent with the notion that some environmental problems can be ameliorated by slowing population growth and increasing income levels

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

how does income inequality affect energy efficiency empirical evidence from 33 belt and road initiative countries abstract at present income distribution and environmental pollution are serious issues faced by the belt and road initiative bri countries and exploring the impact of income inequality on energy efficiency is meaningful for the sustainability of bri countries using the panel data of 33 bri countries from 2000 to 2016 we first evaluate the energy efficiency of the countries by dynamic dea model and then adopt the tobit regression model to investigate the nonlinear effect of income inequality on energy efficiency the results suggest that first during 2000 2016 the overall energy efficiency of 33 bri countries is relatively low falling to 0 38 while the overall energy efficiency of high income bri countries is much higher than that of the middle and low income bri countries second the average energy efficiency of the bri countries has declined since year 2013 third there is an inverted u type effect of income inequality on energy efficiency in the whole sample but the impact of income inequality on energy efficiency is heterogeneous for countries at different income levels specifically in high income bri countries income inequality shows a u type effect on energy efficiency while in middle and low income bri countries the relationship between income inequality and energy efficiency is an inverted u type moreover economic growth positively impacts the energy efficiency while industrialization and energy structure negatively influence the energy efficiency

the interaction of population growth and environmental quality an important question for policy is whether holding constant per capita income and other relevant factors population pressures have a significant effect upon environmental degradation the authors examine the effect of population pressures upon deforestation in 64 developing countries in an attempt to provide relevant empirical findings data on deforestation were drawn from the food and agriculture organizations production yearbook results suggest that a relationship exists between per capita income and deforestation and that for africa rural population density shifts the relationship upward the increase in the rate of deforestation levels off as income increases the rate of growth in per capita income also has a significant negative impact upon deforestation although the magnitude of the effect is small the authors close in stressing that reducing the rate of population growth is not necessarily the best way to reduce the rate of deforestation deforestation in developing countries is really a problem of market failure since property rights are often neither defined nor enforced there is essentially no private cost of deforestation with no long term stake in the land people have no incentive to use land efficiently this situation must be addressed in conjunction with the problems of poverty and population growth

who should abate carbon emissions an international viewpoint abstract we review the optimal pattern of carbon emission abatements across countries in a simple multi country world we model explicitly with the model in chichilnisky 1993b the fact that the atmosphere is a public good within this framework we establish conditions for it to be necessary for optimality that the marginal cost of abatement be the same in all countries these conditions are quite restrictive and amount to either ignoring distributional issues between countries or operating within a framework within which lump sum transfers can be made between countries these results have implications for the use of tradeable emission permits which as normally advocated will lead to the equalization of marginal abatement costs across countries the observation that the atmosphere is a public good implies that we may need to look at a lindahl equilibrium rather than a walrasian equilibrium in tradeable permits

does inequality affect environmental quality evidence from major japanese cities abstract this study investigates whether income inequality affects environmental degradation we use city level data in japan where local governments have limited authority and often use voluntary agreements with private firms we test the hypothesis that inequality weakens residents bargaining power over polluters and has a negative effect on environmental quality our results show that inequality negatively affected air quality in residential and commercial areas during the 1990s but not in industrial areas this evidence suggests that the inequality pollution relationship is not just a correlation but reflects a causal effect of residents bargaining power on environmental quality this implies that equal communities can pressure firms into accepting pollution prevention agreements

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

a household level environmental kuznets curve abstract richer households may create more vehicle emissions because they own more vehicles and drive more poorer households may pollute more because they use high polluting vintages and maintain them less well this paper uses 1993 california vehicle microdata to show that there is a kuznets u shaped hydrocarbon emissions relation

statistical analysis of rainfall insurance payouts in southern india using 40 years of historical rainfall data this paper estimates a distribution for payouts on rainfall insurance policies offered to farmers in the state of andhra pradesh india in 2006 the authors find that the contracts primarily protect households against extreme tail events half the expected value of indemnities paid by the insurance are generated by only 2 percent of rainfall realizations contract payouts are significantly correlated cross sectionally and also inversely associated with real gdp growth the paper discusses the implications of these findings for the potential benefits of insurance to households the risks facing a financial institution underwriting rainfall insurance contracts and pricing

tullock s rent seeking contest with a minimum expenditure requirement vol 93 pg 477 1997 we consider a rent seeking contest of the kind introduced by tullock 1980 in which two players compete for a monopoly rent we extend the contest by requiring that if a player puts forward an effort his expenditures must be larger than or equal to some minimum level we show that depending on the model parameters the number of nash equilibria of the extended model can be zero one two or four furthermore it turns out that the extent of rent dissipation in a nash equilibrium of the extended model can be larger than equal to or smaller than the extent of rent dissipation in the unique nash equilibrium of the original model

insurance credit and technology adoption field experimental evidence from malawi this brief summarizes the insurance credit and technology adoption field experimental evidence from malawi the farmers were offered loans for the november 2006 planting season does production risk suppress the demand for credit the author implemented a randomized field experiment to ask whether provision of insurance against a major source of production risk induces farmers to take out loans to adopt a new crop technology the study sample was composed of roughly 800 maize and groundnut farmers in malawi where by far the dominant source of production risk is the level of rainfall the author randomly selected half of the farmers to be offered credit to purchase high yielding hybrid maize and groundnut seeds for planting in the november 2006 crop season the other half of farmers were offered a similar credit package but were also required to purchase at actuarially fair rates a weather insurance policy that partially or fully forgave the loan in the event of poor rainfall surprisingly take up was lower by 13 percentage points among farmers offered insurance with the loan take up was 33 0 percent for farmers who were offered the uninsured loan there is suggestive evidence that reduced take up of the insured loan was due to farmers already having implicit insurance from the limited liability clause in the loan contract insured loan take up was positively correlated with farmer education income and wealth which may proxy for the individual s default costs by contrast take up of the uninsured loan was uncorrelated with these farmer characteristics

carbon intensity and economic development 1962 1991 a brief exploration of the environmental kuznets curve the relationship between national carbon dioxide emissions intensity co2 emitted per unit of gross domestic product and level of economic development has changed from essentially linear in 1962 to strongly curvilinear in 1991 the inverted u curve reached statistical significance briefly in the early 1970s and increasingly since 1982 this is the result not of groups of countries passing through stages of development but of efficiency improvements in a small number of wealthy countries combined with worse performance in poor and middle income countries the curvilinear relation is deepening and is likely to persist due to constraints on poorer countries in the world economy

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

trade and the environment a partial synthesis there is an emerging consensus in the environmentalist community opposing free trade while some economists view this as simply another outlet for protectionism recent work has begun to move beyond the rhetoric to probe more deeply into the theoretical and empirical relationships between international trade and environmental quality the purpose of the present paper is twofold we first integrate some of the existing literature by using the simple concepts of general equilibrium pollution supply and demand our survey of the trade and environment literature is more

potential demand for drought insurance in burkina faso and its determinants the objectives of this paper are twofold a to estimate demand for formal drought insurance using farm household data in burkina faso and b to find what determines insurance demand the following findings are salient first effective demand is found in all zones which implies inadequacies in households current self insurance strategies second there is much heterogeneity in the strategies to self insure even within zones third the expectation of public food aid decreases demand for drought insurance which suggests that food aid is causing moral hazard fourth households with large livestock holdings can reduce the size of herd by substituting drought insurance for livestock holdings

optimal insurance against climatic experience an optimal insurance contract against a climatic risk is derived in the presence of an uninsurable and dependent aggregate production risk the optimaldesign depends on the stochastic dependency between both sources of uncertainty and on the producer s attitude towards risk especially on his prudent behavior rationalweather insurance purchasing decisions are al so derived the prudent producer responds to actuarially fair weather insurance by increasing his exposure towards risk the u s multiple peril crop insurance program in which indemnity payments are based on the producer s individualyiel ds has been disappointing in that premiums have not been sufficient to cover indemnity payments and administrative costs this failure has induced the u s government to promote alternative insurance policies since 1993 the risk management agency has offered areayield contracts under its group risk plan in selected counties skees black and barnett another alternative is to base the indemnity on a weather index such as rainfall or temperature this policy was proposed in the past by sanderson but has failed to gain acceptance among policy makers the difficulties of rainfall insurance were a subject of debate in australia e g bardsley abey and davenport quiggin 1986 patrick the recent development of weather based instruments on financialmarkets known as weather derivatives for which the payoff depends on the cause of risk rather than on its effect on yield provide new opportunities for covering exposure to unfavorable weather events the objective of this article is threefold first a stochastic production function affected by a climatic risk and by an aggregate production risk where both sources of risk are stochastically dependent is de

end of pipe or cleaner production how to go green in presence of income inequality and pro environmental behavior in this paper we consider a vertically differentiated duopoly model in which a green producer competes with a brown rival in a market in which consumers are environmentally concerned in particular consumers are assumed to value not only the intrinsic quality of a certain product but also its environmental impact this environmental valuation has a positional content consumers attach a positive attribute to the green product while penalizing the brown one in this context we consider the choice of the green firm between cleaner and end of pipe abatement efforts we find that the interplay between the intensity of market competition consumers income disparity and environmental concern can play a crucial role in directing the green producer towards one or the other technological choice more precisely the adoption of cleaner production technologies can be discouraged by low average income and by tough competition while it can be spurred by the moral social incentive towards pro environmental behavior

empirical generalizations in eco innovation a meta analytic approach abstract although discussions on eco innovation are ongoing and the concept is evolving its central idea is highly stimulating thus a great number of studies has been conducted in recent years around the world based on different perspectives contexts and outcomes therefore the identification and analysis of factors related to eco innovation are essential if knowledge in this field is to be improved and consolidated this research aimed to advance our understanding of the different dimensions of eco innovation through a meta analytical review of its antecedents or drivers consequents and moderators thus a total of 71 studies was analysed generating 818 effect sizes and 220 582 cumulative samples the main findings revealed that barriers company capabilities environmental regulation market turbulence information sources r d and company size were significant antecedents to eco innovation it was also noted that a significance relationship exists between eco innovation and firm performance regarding the moderating effect it was observed that culture the economic situation of the country and context influence the relationship between eco innovation and performance the results revealed that countries with a lower hdi presented stronger effects between eco innovation and firm performance than countries with a higher hdi these findings were interesting because they could demonstrate that eco innovation tends to promote more competitive advantage in countries with environmental problems and consequently a lower hdi

a role for capital markets in natural disasters a piece of the food security puzzle abstract natural disaster can create significant shocks in food supplies for small country states these events are very disruptive to the development process market based means for managing natural disaster risk are emerging for example despite the failure of government subsidized crop insurance around the world it is now possible to create index based contracts that would trigger when events that create serious crop failure problems occur this paper investigates the logic for such contracts and some basic designs using measures of rainfall

municipal waste kuznets curves evidence on socio economic drivers and policy effectiveness from the eu waste generation and waste disposal are becoming increasingly prominent in the environmental arena from a policy perspective and in the context of delinking analysis in general waste generation is still increasing proportionally with income and economic and environmental costs associated to landfilling are also increasing this paper provides a comprehensive analysis of waste generation incineration and landfill dynamics based on panel data for the eu25 to assess the effects of different drivers economic structural policy and the eventual differences between western and eastern eu countries we show that for waste generation there is still no waste kuznets curve wkc trend although elasticity to income drivers appears lower than in the past landfill and other policy effects do not seem to provide backward incentives for waste prevention and in terms of landfill and incineration as expected they are respectively decreasing and increasing with policy acting as a strong driver eastern countries appear to be performing generally quite well thus benefiting from eu membership and related policies in terms of environmental performance we can conclude that although absolute delinking is far from being achieved for waste generation there are some first positive signs of an increasing relative delinking for waste generation and robust landfill diversion and varying evidence of a significant role of the eu waste policies implemented in the late 1990s and early 2000s our evidence suggests that if while landfill diversion is currently associated to a delinking partly explained by eu policies waste prevention must be the next objective of waste regulation efforts

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

innovation in pollution control comparisons of the various institutional arrangements for controlling pollutant emissions from individual sources effluent fees effluent control subsidies marketable permits and direct command and control regulation have usually focused on their static efficiency properties and institutional feasibility e g dales 1968 zerbe 1970 baumol and oates 1975 kneese and schultze 1975 marin 1978 mills and white 1978 spence and weitzman 1978 russell 1979 a relatively neglected area has been the study of how each arrangement influences innovation in pollution control a few studies e g kneese and schultze 1975 marin 1978 mills and white 1978 russell 1979 have casually claimed that the control methods that rely on economic incentives provide superior incentives for innovation but there have been few systematic studies of the question this paper provides a simple model of pollution control innovation by a profitmaximizing polluter who is subject to the various control methods the consequences of the methods will be explored in three major contexts first we assume that the polluter and the innovation is a small enough part of the overall pollution problem so that none of the important marginal conditions are changed by the innovation second we assume that the polluter and the innovation are important enough so that marginal conditions are changed by the innovations but that the governmental authority determining pollution control incentives or levels fails to make the appropriate adjustments third we again assume that the innovation causes marginal conditions to change but in this case the governmental authority makes the appropriate adjustments we use the term ratcheting to describe this last phenomenon in all cases we assume that the innovating polluter correctly predicts the reactions of the governmental authority and bases his innovation decisions on that prediction a profit maximizing entrepreneur would normally be expected to adopt any innovation that promised gains present discounted value to him in excess of initial

concept and unintended consequences of weather index insurance the case of mexico recently weather index insurance wii has received considerable attention as a tool to insure farmers against weather related risks particularly in developing countries donor organizations local governments insurance companies development economists as well as agricultural economists are discussing the costs and benefits of wii while the literature on wii has mainly focused on many cases in africa and asia in this article we analyze the wii program in mexico which is one of the largest wii programs worldwide in this context we discuss potentially important spill over effects on related markets which so far have not been considered in the academic literature first we argue that wii creates disincentives to invest in other non insured crops leading to potential overspecialization and monoculture secondly wii generates disincentives to invest in irrigation systems because farmers are insured only as long as production takes place on non irrigated land third in case of catastrophic events food prices can potentially inflate with indemnity payments at the expense of the uninsured poor we also suggest that in mexico the thresholds of the weather index be continuously re calibrated in order to adjust for the development of drought resistant seeds finally the index could relatively easily be extended to account for precipitation variances we argue that these factors and spillover effects should be accounted for in cost benefit analysis of wii this abstract was borrowed from another version of this item

mechanisms explaining the impact of economic inequality on environmental deterioration abstract rising economic inequality often considered intrinsically harmful is increasingly being viewed as having a number of secondary impacts as well including impacts on health and economic growth the ongoing nature of today s environmental crisis also raises questions about inequality s role in environmental deterioration despite the large number of papers that have been written on this topic no theoretical or empirical consensus presently exists firstly our article identifies that authors conclusions in this area depend on their hypotheses regarding 1 the relationship between individual income and individual environmental pressure 2 the impact of inequality on the social norms that influence individual environmental pressure 3 the interests that social groups have in degrading or protecting the environment 4 how these interests play out in terms of political demands and 5 how these political demands translate into political decisions secondly the study shows that despite enabling a general test of the causal relationship between inequality and the environment the empirical methods utilised do not account for the full range of theoretical mechanisms in play hence the suggestion that a research programme be launched to conduct empirical studies of the five aforementioned hypotheses by applying a recursive approach

income inequality and the development of environmental technologies within rich countries a large dispersion in the capacity of generating environmental innovations appears correlated to the level of inequality previous works analyze the relationship between inequality and environmental quality in a static setting this paper builds a dynamic model more suitable to analyze technological externalities driven by the emergence of a new demand for green products under fairly general assumptions on technology and preferences we show that 1 the relationship between inequality and environmental innovation is highly non linear and crucially depends on per capita income 2 an excessive inequality harms the development of environmental technologies especially in rich countries key to our results is the fact that externalities generated by pioneer consumers of green products benefit the entire population only for relatively low income distances the empirical analysis robustly confirms our theoretical results that is whereas for rich countries inequality negatively affects the diffusion of innovations per capita income is paramount in poorer ones

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

determinants of environmental innovation in us manufacturing industries abstract this paper provides new evidence on the determinants of environmental innovation we employ panel data models to study how environmental innovation by us manufacturing industries responded to changes in pollution abatement expenditures and regulatory enforcement during the period 1983 through 1992 we find that 1 environmental innovation as measured by the number of successful environmental patent applications granted to the industry responded to increases in pollution abatement expenditures however 2 increased monitoring and enforcement activities related to existing regulations did not provide any additional incentive to innovate we also find some empirical evidence that environmental innovation is more likely to occur in industries that are internationally competitive

weather index drought insurance an ex ante evaluation for millet growers in niger in the sudano sahelian region which includes south niger the inter annual variability of the rainy season is high and irrigation is limited as a consequence bad rainy seasons have a massive impact on crop yield and regularly result in food crises traditional insurance policies based on crop damage assessment are not available because of asymmetric information and high transaction costs compared to the value of production we assess the risk mitigation capacity of an alternative form of insurance which has been implemented at a large scale in india since 2003 insurance based on a weather index we compare the efficiency of various weather indices to increase the expected utility of a representative risk averse farmer we show the importance of using plot level yield data rather than village averages which bias results due to the presence of idiosyncratic shocks we also illustrate the need for out of sample estimations in order to avoid overfitting even with the appropriate index and assuming substantial risk aversion we find a limited gain of implementing insurance which roughly corresponds to or slightly exceeds the cost observed in india for implementing such insurance policies however when we separately treat the plots with and without fertilisers separately we see that the benefit of insurance is slightly higher in the former case this suggests that insurance policies may slightly increase the use of risk increasing inputs such as fertilisers and improved cultivars and hence improve average yields which remain very low in the region

demand for a labor based drought insurance scheme in ethiopia a stated choice experiment approach index based weather insurance is increasingly used to manage weather related risks in smallholder agriculture however cash constrained smallholders often lack the resources to pay an insurance premium which may undermine its wider adoption this article investigates alternative insurance payment methods that may help to enhance the adoption of index based weather insurance we use a choice experiment to elicit smallholders willingness to pay in cash or labor for index based weather insurance in four districts in the south central highlands of ethiopia the insurance schemes were created using a fractional factorial design with three factors work cash and payout rate we analyze the choice data using a random parameter mixed logit model we find that the average participants need a subsidy to pay cash for insurance because their willingness to pay is less than the expected cost of the insurance on average they are willing to pay only 0 81 etb ethiopian currency to get an expected yearly payout of 1 etb however most are willing to participate in work for insurance programs at lower daily wage rates than is common for other work programs in ethiopia

innovation and the international diffusion of environmentally responsive technology abstract new evidence is presented on environmental innovation and diffusion over the 1970s and 1980s at a global level a substantial amount of innovations occurred in the united states japan and germany the share of environmental patents in all patents varied between 0 6 and 3 and as such was higher than the corresponding share of pollution abatement expenditure in gdp japanese environmental innovation rates were consistently high certain plausible connections between environmental regulation and innovation also emerge across these three countries and over time innovation responded to pollution abatement expenditure an indicator of the severity of environmental regulations environmental patenting rates in developing countries were also high reaching 2 in many years in brazil developing country innovators obtained a non trivial number of patents most of which appear geared towards adapting imported technologies to local conditions however domestic innovation was only one path to new technologies imports of disembodied environmental technologies foreign patents registered in developing countries were substantial foreign patents were typically important or generic patents evidence also suggests that such patents protected intellectual property in equipment exported developing countries especially in east asia often chose to obtain technologies embodied in pollution abatement equipment
