political instability corruption and policy formation the case of environmental policy abstract this paper develops a theory of environmental policy formation taking into consideration the degree of corruptibility and political turbulence the predictions that emerge are that the interaction between the two variables is important political instability has a negative effect on the stringency of environmental regulations if the level of corruption is low but a positive effect when the degree of corruption is high corruption reduces the stringency of environmental regulations but the effect disappears as political instability increases the empirical findings are fully consistent with the predictions of the model

estimating the social cost of pesticide use an assessment from acute poisoning in brazil abstract the intensive use of pesticides in countries like brazil has ignored structural and institutional shortfalls such as the lack of workforce training for the new difficult to implement technologies and the institutional vulnerability of the environmental protection health and safety sectors as a result we have invisible or social environmental and health costs which end up being socialised with the farmer in general having no incentives to recognise and internalise them this study is intended to review and develop this problem in the light of the brazilian reality to this end we make use of an empirical exercise to illustrate estimation of the social cost associated with acute poisoning by pesticide using the prevs ibge data harvest forecast research in the state of parana brazil the results suggest that for maize the costs of acute poisoning could represent 64 of the benefits of using herbicides and insecticides and in the best of hypotheses when some risk factors are eliminated they may reach 8 of the benefits of the use of these products similarly when we examine future scenarios for five and ten years we find less encouraging results as in ten years the costs of acute poisoning could reach around 85 of the benefit of using insecticides and herbicides for maize however there is the encouraging news that if preventive measures were taken during this time the gains would be considerable about 6 5 times greater we conclude that an assessment of the real benefits involved with pesticides in brazil is required principally in regard to the smallholder where farmers need more training in the use or even the elimination of these hazardous substances there are sustainable technological options available which are economically efficient especially if we consider the social environmental and health costs in this context it is worth highlighting the role of regulatory measures as a mechanism which can reorient generation of negative external costs through the reduction of current incentives in the socialisation of private costs

agrifood supply chain private sector standards and farmers health evidence from kenya this article evaluates the impact of adoption of european union eu private sector standards on farmers health in rural kenya the study utilizes cross sectional farm household level data collected in 2006 from a randomly selected sample of 439 small scale export farmers we estimate the casual impact by utilizing a two stage poisson regression model two stage standard treatment effect model as well as by regression based on propensity score to assess the robustness of the results using these techniques we demonstrate that the pesticide ascribed incidence of acute illness symptoms and the associated cost of illness significantly decrease with the adoption of standards ceteris paribus farmers who adopt standards experience 70 lesser incidence of acute illness and spent about 50 60 less on restoring their health than nonadopters although standards can potentially prevent resource poor smallholders from maintaining their position in lucrative export markets they can also result in positive changes in the health of those farmers who do adopt them as shown by these results this implies that if adopted on a large scale standards may reduce production externalities corroborating the view that they may serve as a catalyst to transform production systems in developing countries

legislative organization and pollution taxation the role of political institutions in shaping public policy has been analyzed in isolation from corruption and legislative organization specifically bicameralism has received minimal attention we analyze pollution taxation when decisions are influenced by several veto players such as legislative chambers our theory predicts that an increase in the number of veto players e g moving from uni to bi cameralism pushes the pollution tax towards the social optimum with the effect being conditional on corruption as such dispersion around the optimal tax is lower under bicameralism empirical tests using data from 86 countries support the theory

bicameralism and its consequences for the internal organization of legislatures theories of organization of legislatures have mainly focused on the u s congress explaining why committee systems emerge there but not explaining variance in organization across legislatures of different countries to analyze the effects of different constitutional features on the internal organization of legislatures we adopt a vote buying model and consider the incentives to delegate decision rights in a game among legislative chambers we show how presidential veto power and bicameral separation can encourage a legislative chamber to create internal veto players or supermajority rules while a unicameral structure can encourage legislators to delegate power to a leader

separation of powers and political accountability political constitutions are incomplete contracts and therefore leave room for abuse of power in democracies elections are the primary mechanism for disciplining public officials but they are not sufficient separation of powers between executive and legislative bodies also helps to prevent the abuse of power but only with appropriate checks and balances checks and balances work by creating a conflict of interest between the executive and the legislature yet requiring both bodies to agree on public policy in this way the two bodies discipline each other to the voters advantage under appropriate checks and balances separation of powers also helps the voters elicit information

corruption federalism and policy formation in the oecd the case of energy policy we investigate whether the effect of government corruption is conditional on a country s institutional structure federal systems have an additional layer of government making lobbying relatively more costly we investigate whether the effect of government corruption on environmental policy in the form of restrictions on energy use is conditional on a federal system being in place using 1982 96 data from 11 industry sectors in 12 oecd economies we find that while greater government corruption reduces the stringency of environmental policy the effect declines in federal systems

what mean impacts miss distributional effects of welfare reform experiments labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings transfers and income yet most welfare reform research focuses on mean impacts we investigate the importance of heterogeneity using random assignment data from connecticut s jobs first waiver which features key elements of post 1996 welfare programs estimated quantile treatment effects exhibit the substantial heterogeneity predicted by labor supply theory thus mean impacts miss a great deal looking separately at samples of dropouts and other women does not improve the performance of mean impacts we conclude that welfare reform s effects are likely both more varied and more extensive than has been recognized

political internalization of economic externalities and environmental policy abstract this paper derives the characteristics of endogenous environmental policy in a common agency model of politics and proceeds to show that competition between lobby groups is an important source of internalization of economic externalities our analysis generalizes bhagwati s principle of targeting to the case of distorted political markets moreover we show that the politically optimal structure of environmental taxes incorporates a pigouvian adjustment however since lobby groups care about the distribution of income as well as about efficiency the equilibrium structure of taxes differs considerably from the pigouvian rule

the impact of bt cotton on poor households in rural india the impact of genetically modified gm crops on the poor in developing countries is still the subject of controversy while previous studies have examined direct productivity effects of bacillus thuringiensis bt cotton and other gm crops little is known about wider socioeconomic outcomes we use a microeconomic modelling approach and comprehensive survey data from india to analyse welfare and distribution effects in a typical village economy bt cotton adoption increases returns to labour especially for hired female workers likewise aggregate household incomes rise including for poor and vulnerable farmers hence bt cotton contributes to poverty reduction and rural development

surplus distribution from the introduction of a biotechnology innovation we examine the distribution of welfare from the introduction of bt cotton in the united states in 1996 the welfare framework explicitly recognizes that research protected by intellectual property rights generates monopoly profits and makes it possible to partition these rents among consumers farmers and the innovating input firms we calculate a total increase in world surplus of 240 3 million for 1996 of this total the largest share 59 went to u s farmers the gene developer monsanto received the next largest share 21 followed by u s consumers 9 the rest of the world 6 and the germplasm supplier delta and pine land company 5

games played through agents in the laboratory a test of prat rustichini s model abstract from the regulation of sports to lawmaking in parliament in many situations one group of people agents make decisions that affect the payoffs of others principals who may offer action contingent transfers in order to sway the agents decisions prat and rustichini 2003 characterize pure strategy equilibria of such games played through agents specifically they predict the equilibrium outcome in pure strategies to be efficient we test the theory in a series of experimental treatments with human principals and computerized agents the theory predicts remarkably well which actions and outcomes are implemented but subjects transfer offers deviate systematically from equilibrium we show how quantal response equilibrium accounts for the deviations and test its predictions out of sample our results show that quantal response equilibrium is particularly well suited for explaining behavior in such games

the provision of public goods under alternative electoral incentives politicians who care about the spoils of office may underprovide a public good because its benefits cannot be targeted to voters as easily as pork barrel spending we compare a winner take all system where all the spoils go to the winner to a proportional system where the spoils of office are split among candidates proportionally to their share of the vote in a winner take all system the public good is provided less often than in a proportional system when the public good is particularly desirable we then consider the electoral college system and show that it is particularly subject to this inefficiency

electoral rules and environmental policy abstract this paper investigates the effect of electoral rules on environmental policymaking using several estimators from the program evaluation literature we find that governments set stricter environmental policies under proportional as opposed to majoritarian systems

does electoral accountability affect economic policy choices evidence from gubernatorial term limits this paper analyzes the behavior of u s governors from 1950 to 1986 to investigate a reputation building model of political behavior we argue that differences in the behavior of governors who face a binding term limit and those who are able to run again provides a source of variation in discount rates that can be used to test a political agency model we find evidence that taxes spending and other policy instruments respond to a binding term limit if a democrat is in office the result is a fiscal cycle in term limit states which lowers state income when the term limit binds

the size and scope of government comparative politics with rational politicians we try to demonstrate how economists may engage in research on comparative politics relating the size and composition of government spending to the political system a downsian model of electoral competition and forward looking voting indicates that majoritarian as opposed to proportional elections increase competition between parties by focusing it into some key marginal districts this leads to less public goods less rents for politicians more redistribution and larger government a model of legislative bargaining and backward looking voting indicates that presidential as opposed to parliamentary regimes increase competition between both politicians and voters this leads to less public goods less rents for politicians less redistribution and smaller government we confront these predictions with cross country data from around 1990 controlling for economic and social determinants of government spending we nd strong and robust support for the prediction that the size of government is smaller under presidential regimes and weaker support for the prediction that majoritarian elections are associated with less public goods

electoral systems and public spending we study the effects of electoral institutions on the size and composition of public expenditure in oecd and latin american countries we emphasize the distinction between purchases of goods and services which are easier to target geographically and transfers which are easier to target across social groups we present a theoretical model in which voters anticipating government policymaking under different electoral systems have an incentive to elect representatives more prone to transfer public good spending in proportional majoritarian systems the model also predicts higher total primary spending in proportional majoritarian systems when the share of transfer spending is high low after dee ning rigorous measures of proportionality to be used in the empirical investigation we e nd considerable support for our predictions

the costs and benefits of refuge requirements the case of bt cotton abstract refuge requirements have been the primary regulatory tool to delay pest resistance to bt crops this paper presents a simple method to estimate the annual cost of refuges to producers applying it to bt cotton it also examines broader welfare impacts estimating how bt cotton acreage restrictions affect producer surplus consumer surplus seed supplier profits and commodity program outlays the implications of grower adoption behavior partial adoption aggregate adoption and refuge choice for regulatory costs are examined empirical examples illustrate how providing multiple refuge options significantly reduces regulatory costs

fifteen years of bt cotton in china the economic impact and its dynamics summary even though the economic benefit of bt cotton adoption in the short run has been well documented the dynamics of this benefit remain unclear in particular the possibility of pest resistance build up and secondary pest outbreaks has caused concern regarding the sustainability of this economic benefit in the long run hence this study analyzes the economic impact of bt cotton and its dynamics in china using nationally representative long panel data for 1997 2012 we show that this economic benefit continues 15 years after the commercialization of bt cotton

valuing environmental and health risk in agriculture a choice experiment approach to pesticides in italy abstract the widespread use of pesticides in agriculture shows a complex ramification of multiple negative externalities ranging from food safety related effects to the deterioration of farmland ecosystems recent research has demonstrated that the assessment of the economic implications of such negative processes is fraught with many uncertainties this paper presents the results of an empirical study recently conducted in northern italy aimed at estimating the economic value of reducing the wide ranging impacts of pesticide use by deploying a choice experiment approach the experimental design provides a meaningful tool to assign monetary values to the negative environmental effects associated with agrochemicals use in this connection the paper addresses in particular the reduction of farmland biodiversity groundwater contamination and harm to human health the resulting estimates confirm that on average respondents demonstrate a substantial willingness to pay a premium for agricultural goods in particular foodstuffs produced in environmentally benign ways

dynamic common agency a general model of dynamic common agency with symmetric information is considered the set of truthful markov perfect equilibrium payoffs is characterized and the efficiency properties of the equilibria are established a condition for the uniqueness of equilibrium payoffs is derived for the static and the dynamic game the payoff is unique if and only if the payoff of each principal coincides with his marginal contribution to the social value of the game the dynamic model is applied to a game of agenda setting

biofuels adoption in nigeria attaining a balance in the food fuel feed and fibre objectives abstract the drive towards economic development in nigeria brings about the pursuit of many competing objectives whose attainments depend on limited resources biofuels adoption has been set as an important path among other options for pursuing economic growth and development for the country the federal government of nigeria fgn is currently promoting the production processing and utilization of biofuels in the transport and energy sectors the article examines biofuels adoption in nigeria vis a vis the attainment of a balance in the food fuel feed and fibre objectives crops already profiled as preferred sources of feedstock for the primary biofuels production are also crucial for food feed and fibre the resources needed for producing these crops are limited hence the need for a balance this paper derived data from secondary sources including the food and agriculture organization fao the paper explores some aspects of biofuels sustainability and present recommendations for attaining a balance in the multiple objectives for attaining socioeconomic development

corruption and development a review of issues in this paper we start with a discussion of some of the different denotations of the problem of corruption we then consider the ways in which the damaging consequences of corruption operate in a developing economy while not ignoring its possible redeeming features in some cases we pursue the question of why corruption is perceptibly so different in different societies and also persistent finally we examine the feasible policy issues that arise in this context

potential impacts of bt eggplant on economic surplus and farmers health in india in this article the potential impacts of bt eggplant technology in indian agriculture are analyzed several proprietary bt hybrids are likely to be commercialized in the near future based on field trial data it is shown that the technology can significantly reduce insecticide applications and increase effective yields comprehensive farm survey data are used to project farm level effects and future adoption rates simulations show that the aggregate economic surplus gains of bt hybrids could be around us 108 million per year consumers will capture a large share of these gains but farmers and the innovating company will benefit too as the company has also shared its technology with the public sector bt open pollinated varieties might become available with a certain time lag this would make the technology more accessible especially for resource poor farmers entailing further improvements in welfare and distribution effects the wider implications of the private public technology transfer are discussed furthermore the potential benefits for farmers health resulting from reduced insecticide applications are examined using an econometric model and a cost of illness approach these benefits are worth an additional 3 4 million per year yet they constitute only a small fraction of the technology s environmental and health externalities more research is needed for comprehensive impact analysis

governing uncertain and unknown effects of genetically modified crops this paper analyzes the capabilities of three different governance regimes for adequately handling uncertain and unknown effects of genetically modified gm crops adequate handling requires the development of sound procedures for identification of uncertainty and ignorance ui gm crops are produced by private firms and the government decides whether the crops should be marketed gr2 and gm crops are produced and the government decides whether the crops should be marketed gr3 the effect of bringing the civil society into the decision making process is also analyzed gr3 will be stronger in cooperative adaptation and communicative rationality than gr2 public research organizations have fewer conflicts of interest with the government than private firms and academic norms are important difficulties in proving harm and identifying the responsible firm will make gr1 weak in cooperative adaptation and communicative rationality

electoral rules and corruption is corruption systematically related to electoral rules recent theoretical work suggests a positive answer but little is known about the data we try to address this lacuna by relating corruption to different features of the electoral system in a sample of about eighty democracies in the 1990s we exploit the cross country variation in the data as well as the time variation arising from recent episodes of electoral reform the evidence is consistent with the theoretical priors larger voting districts and thus lower barriers to entry are associated with less corruption whereas larger shares of candidates elected from party lists and thus less individual accountability are associated with more corruption individual accountability appears to be most strongly tied to personal ballots in plurality rule elections even though open party lists also seem to have some effect because different aspects roughly offset each other a switch from strictly proportional to strictly majoritarian elections only has a small negative effect on corruption jel e62 h3

comparative politics and public finance we propose a model with micropolitical foundations to contrast different political regimes compared to a parliamentary regime the institutions of a presidential congressional regime produce fewer incentives for legislative cohesion but more separation of powers these differences are reflected in the size and composition of government spending a parliamentary regime has redistribution toward a majority less underprovision of public goods and more rents to politicians a presidential congressional regime has redistribution toward powerful minorities more underprovision of public goods but less rents to politicians the size of government is smaller under a presidential regime this last prediction is consistent with cross country data

energy use and economic development a comparative analysis of useful work supply in austria japan the united kingdom and the us during 100 years of economic growth this paper presents a societal level exergy analysis approach developed to analyse transitions in the way that energy is supplied and contributes to economic growth in the uk the us austria and japan throughout the last century we assess changes in exergy and useful work consumption energy efficiency and related gdp intensity measures of each economy the novel data provided elucidate certain characteristics of divergence and commonality in the energy transitions studied the results indicate that in each country the processes of industrialization urbanisation and electrification are characterised by a marked increase in exergy and useful work supplies and per capita intensities there is a common and continuous decrease in the exergy intensity of gdp moreover for each country studied the trend of increasing useful work intensity of gdp reversed in the early 1970s coincident with the first oil crisis

food versus fuel what do prices tell us abstract sorting out the impacts of biofuels on global agricultural commodity prices is impossible without turning to data and distinguishing between the short run versus the long run impacts using time series prices on fuels and agricultural commodities the aim is to investigate the long run cointegration of these prices simultaneously with their multivariate short run interactions results indicate no direct long run price relations between fuel and agricultural commodity prices and limited if any direct short run relationships in terms of short run price movements sugar prices are influencing all the other agricultural commodity prices except rice with sugar the number one world input for ethanol results indicate increased ethanol production is potentially influencing short run agricultural commodity prices overall results support the effect of agricultural commodity prices as market signals which restore commodity markets to their equilibria after a demand or supply event shock

comparative politics and environmental taxation abstract in this paper we take a step towards understanding the role of democratic institutions on the level of pollution taxation persson et al j polit economy 108 2000 1121 argue that presidential congressional regimes set lower taxes than parliamentary regimes this conclusion results from the checks and balances built into the former and the higher degree of legislative cohesion in the latter we test this prediction on gasoline and diesel prices using the method of propensity score matching along with data from 86 democratic countries the empirical evidence is consonant with the theory we find that ceteris paribus the average price of super gasoline is 0 14 0 20 less per liter in presidential congressional systems the average price of diesel gasoline is 0 11 0 14 less per liter

dynamic modeling of causal relationship between energy consumption co2 emissions and economic growth in india abstract the paper investigates the causality relationships among energy consumption carbon dioxide co2 emissions and income in india using a dynamic modeling approach the paper also utilises an innovation accounting method to investigate profiles of the macroeconomic variables persisting from an unanticipated shock in innovation our results provide evidence of the existence of bi directional granger causality between energy consumption and co2 emissions in the long run but neither co2 emissions nor energy consumption causes movements in real income there is no causality relationship between energy consumption and income in any direction in the long run implying that india could follow energy conservation and efficiency improvement policies without impeding economic growth this will allow india to reduce co2 emissions without affecting its economic growth and contribute significantly towards combating global warming as well

estimating the adoption of bt eggplant in india who benefits from public private partnership the study analyzes ex ante the adoption of insect resistant bt eggplant technology in india farmers willingness to pay wtp is estimated using the contingent valuation method given the economic importance of insect pests in eggplant cultivation the average wtp for bt hybrids is more than four times the current price of conventional hybrid seeds since the private innovating firm has also shared its technology with the public sector proprietary hybrids will likely get competition through public open pollinated bt varieties after a small time lag this will reduce farmers wtp for bt hybrids by about 35 thus decreasing the scope for corporate pricing policies nonetheless ample private profit potential remains analysis of factors influencing farmers adoption decisions demonstrates that public bt varieties will particularly improve technology access for resource poor eggplant producers the results suggest that public private partnership can be beneficial for all parties involved 2006 published by elsevier ltd

the economics of biotechnology under ecosystem disruption abstract economic analysis of chemical pesticide use has shown that the interactions between plants pests damage control technology and state of the ecosystem are important variables to be considered hence a bio economic model was developed for the assessment of bt variety and pesticide based control strategies of the cotton bollworm in china the model simulates plant growth the dynamics of pest populations and of natural enemies the model predictions are used as major inputs for a stochastic micro level profit model of alternative control strategies results show that 1 productivity effects of bt varieties and pesticide use depend on the action of natural control agents and 2 the profitability of damage control measures increases with the severity of ecosystem disruption the findings highlight the importance of the choice of the counterfactual scenario in the assessment of the impact of agricultural biotechnology also some doubts are raised whether the high benefits of bt cotton varieties claimed by previous studies based on cross section comparisons are realistic

cotton farmers willingness to pay for pest management services in northern benin this study was carried out to assess cotton farmers willingness to pay wtp for pest management services in northern benin targeted staggered control tsc has been introduced to reduce pesticide use in cotton cropping and generate an estimated benefit of fcfa48 800 74 40 per cotton hectare accruing from increased productivity and reduced pesticide cost however tsc application requires extra time for pest identification and scouting and its adoption remains low due to the lack of funding to boost farmers awareness and cover training costs an interval regression model was used to analyze responses to a double bounded contingent valuation survey with data collected from 300 cotton farmers the results showed that 87 3 of cotton farmers were willing to pay for tsc services annual wtp per cotton hectare was estimated at fcfa16 962 25 80 revealing an existing demand for tsc adoption respondents wtp was driven by farm and socio economic characteristics financial mechanisms managed by farmers could thus potentially foster technology adoption and in turn generate economic and environmental benefits

corruption and the composition of government expenditure abstract this paper asks whether predatory behavior by corrupt politicians distorts the composition of government expenditure corruption is found to reduce government spending on education in a cross section of countries

sustainability of biofuels in latin america risks and opportunities several latin american countries are setting up biofuel programmes to establish alternative markets for agricultural commodities this is mainly triggered by the current success of brazilian bioethanol production for the domestic market and for export furthermore the global biofuel market is expected to increase due to ambitious biofuel programmes in the eu and in the usa colombia venezuela costa rica and guatemala are focusing on bioethanol production from sugarcane whereas biofuel production in argentina is based on soy biodiesel recent developments of the biofuel sector take place extremely rapid especially in argentina which became one of the five largest biodiesel producers in the world in 2008 till date no specific biofuel sustainability certification systems have been implemented in latin american as well as on global level this fact and the predominant use of food crops for biofuel production raise concerns about the sustainability of biofuel production related to environmental and social aspects this paper provides an overview of the hotspots of conflicts in biofuel production in latin america it investigates presently available sustainability tools and initiatives to ensure sustainable biofuel production in latin america finally it provides an outlook on how to integrate sustainability in the latin american biofuel sector

legislative organization and government spending cross country evidence abstract the law of 1 n posits that an increase in the number of elected representatives fuels excessive government spending despite its wide acceptance as a stylized fact the law of 1 n has received only limited empirical scrutiny and the existing evidence for the american states provides mixed support for the thesis this paper examines the law of 1 n in bicameral and unicameral legislative structures using a cross section of democratic countries the results indicate that legislative size matters under both legislature structures but bicameralism dampens the 1 n effect relative to unicameralism

to ban or not to ban foreign lobbying and cross national externalities this paper studies the costs and benefits of foreign lobbying we show how and when foreign lobbying can help internalize cross national externalities we argue that this is an often overlooked benefit of foreign lobbying we also study under what conditions a constitutional rule banning foreign lobbying is in the national interest of a country a key factor in this calculus is whether the interests of foreign lobby groups and domestic unorganized groups coincide or not we illustrate the logic with examples from trade policy and environmental regulation bannir ou ne pas bannir lobbying etranger et effets externes transnationaux ce texte etudie les couts et avantages du lobbying etranger on montre quand et comment que le lobbying etranger peut aider a internaliser des effets externes transnationaux on suggere que c est souvent un avantage qu on est porte a negliger du lobbying etranger on etudie sous quelles conditions une regle constitutionnelle bannissant le lobbying etranger peut etre dans l interet national d un pays un facteur cle dans ce calcul est le fait que les interets des groupes etrangers coincident ou non avec ceux des groupes nationaux non organises on illustre la logique sous jacente a l aide d exemples portant sur la politique commerciale et la reglementation environnementale

pesticide risk valuation in empirical economics a comparative approach abstract pesticide use in agriculture poses several risks to both human health and nontarget agro ecosystems due to lack of information on the monetary value of reducing pesticide risks it is difficult to perform an economic analysis that addresses social efficiency of policy and draws conclusions about the appropriate degree of regulation the aim of the current paper is to present a critical overview of the empirical literature on pesticide risk valuation that provides disaggregate willingness to pay estimates wtps of pesticide risks reduction recent multidimensional classification methods such as coined decision tree analysis are used in a comparative approach as tools for explaining the differences in empirical research findings the analysis shows that the order of magnitude of wtps is related to both the valuation technique and to the data available from biomedical and ecotoxicological literature it also shows that wtp estimates of pesticide risks cannot be simply averaged over several empirical studies the order of magnitude of a wtp estimate is in fact related to the specific type of risk and to the nature of the risk scenario considered as well to lay people s subjective perception of risks

valuing financial health and environmental benefits of bt cotton in pakistan data from a farm survey and choice experiment are used to value the benefits of bt cotton in pakistan unlike previous research on the economic impacts of bt which mostly concentrated on financial benefits in terms of gross margins we also quantify and monetize positive externalities associated with technology adoption due to lower chemical pesticide use on bt cotton plots there are significant health advantages in terms of reduced incidence of acute pesticide poisoning and environmental advantages in terms of higher biodiversity and lower soil and groundwater contamination these positive externalities are valued at us 79 per acre of which half is attributable to health and the other half to environmental improvements adding average gross margin gains of us 204 results in an aggregate benefit of us 283 per acre of bt or us 1 7 billion for the total bt cotton area in pakistan

energy consumption and economic growth in the usa evidence from renewable energy abstract recent debates about renewable energy consumption manifest two main expectations firstly renewable energy consumption should contribute to economic growth and secondly it should not cause damage on environment this study focuses on the first issue by applying toda yamamoto procedure and bootstrap corrected causality test for the us since empirical literature criticizes the toda yamamoto test which bases on asymptotic distribution the models consist of real gdp employment investment and kinds of renewable energy consumption only one causal relationship was found from biomass waste derived energy consumption to real gdp no causal relationship was found between real gdp and all of the other renewable energy kinds total renewable energy consumption geothermal energy consumption hydro electric energy consumption biomass energy consumption and biomass wood derived energy consumption that is using of energy from waste cause not only solving the dumping problems but also it contributes to real gdp for policy purpose the results of this study suggest that countries should concentrate on energy producing from waste as an alternative energy resource

corruption pollution and the kuznets environment curve abstract this paper examines the implications of corruption and rent seeking behavior by the government for the relationship between pollution and growth cases of both cooperative and non cooperative interaction between the government and the private firm are studied it is shown that corruption is not likely to preclude the existence of an inverted u shaped kuznets environmental curve under both these cases however for any level of per capita income the pollution levels corresponding to corrupt behavior are always above the socially optimal level further the turning point of the kuznets curve takes place at income and pollution levels above those corresponding to the social optimum

do constitutions cause large governments quasi experimental evidence abstract how do constitutional rules for elections and legislation affect the size of government we ask this question in a new sample of about 80 countries in the 1990s in addition to conventional regression methods we use quasi experimental matching methods which more convincingly address legitimate criticisms of causal inference from cross country data both sets of estimates suggest that presidential regimes and majoritarian elections produce smaller governments

when the weak win the role of investment in environmental lobbying abstract old and environmentally damaging industries often lobby effectively for less stringent regulations and are slow to adopt new and cleaner technologies this paper explains the lobbying success of these industries in terms of the strategic role of investment as a credible commitment device it is demonstrated that if governments are predisposed to special interest groups underinvestment in new technology enables firms to lobby more effectively such industries are shown to be better placed to extract policy concessions despite contributing less to the government in political donations the analysis therefore suggests that political considerations may provide a significant incentive for firms to reject environmentally beneficial investments even when these lower production costs

testing assumptions underlying economic research on transgenic food crops for third world farmers evidence from cuba guatemala and mexico abstract transgenic crop varieties tgvs are being promoted as essential for improving small scale third world sstw agriculture most economic research on this topic makes critical untested assumptions including that farmers will choose tgvs over other varieties because tgvs are economically optimal and because farmers are risk neutral profit maximizers we tested these assumptions using data from a survey of 334 farmers in 6 communities in cuba guatemala and mexico in which farmers ranked 4 real and hypothetical maize varieties for eating and sowing our results did not support these assumptions most farmers preferred farmer varieties for sowing and especially for eating avoiding tgvs a preference associated with being risk averse and with non monetary preferences farmers more integrated into modern agriculture were more likely to choose tgvs these results suggest that farmers most in need of support and most important for conserving genetic diversity are least favorable toward tgvs and that alternative ways of improving sstw agriculture should receive more attention

impact of bt cotton on pesticide poisoning in smallholder agriculture a panel data analysis while substantial research on the productivity and profit effects of bt cotton has been carried out recently the economic evaluation of positive and negative externalities has received much less attention here we focus on farmer health impacts resulting from bt related changes in chemical pesticide use previous studies have documented that bt cotton has reduced the problem of pesticide poisoning in developing countries but they have failed to account for unobserved heterogeneity between technology adopters and non adopters we use unique panel survey data from india to estimate unbiased effects and their developments over time bt cotton has reduced pesticide applications by 50 with the largest reductions of 70 occurring in the most toxic types of chemicals results of fixed effects poisson models confirm that bt has notably reduced the incidence of acute pesticide poisoning among cotton growers these effects have become more pronounced with increasing technology adoption rates bt cotton now helps to avoid several million cases of pesticide poisoning in india every year which also entails sizeable health cost savings

bicameral legislatures and fiscal policy john stuart mill s observation in the mid 19th century is clearly outdated the two chamber question receives scant attention in modern political economy the absence of continued debate might simply reflect a general satisfaction with the dual chambered structure as a desirable democratic institution most developed democracies and all but one of the american states have adopted a bicameral legislative structure in this paper we stress the many variations in bicameralism even among the american states and the effects these variations have on policy making and fiscal outcomes put simply bicameralism is not an all or none institution instead bicameralism is a variable institution that alters the identity of the median legislator within each chamber and determines the similarity of the dominant coalitions between the two chambers in this perspective the impact of bicameralism on policy comes principally from the different bases of representation across the two chambers moreover the analysis stresses that the degree of bicameralism changes regularly as a consequence of the redistricting process the remainder of the paper is organized as follows section 2 reviews the main conceptual arguments underlying the function of a bicameral organization section 3 examines implications for fiscal policy using data from the american states we develop several measures of bicameralism using detailed constituency data on economic and demographic characteristics at the level of state legislative districts we then use these measures to examine the effect of interdistrict constituent homogeneity on total state government spending as well as on the major com
