models for referendum data the structure of discrete choice models for contingent valuation abstract in 1979 bishop and heberlein introduced an appealing variant of the contingent valuation method which required only yes or no responses hanemann developed a utility theoretic interpretation of the yes no responses which has helped popularize the approach recently cameron has offered another interpretation also utility theoretic which she argues is more general than the hanemann random utility model this paper compares the deterministic models suggested by hanemann and cameron showing them to be dual to each other it shows that correct specification of either function must exclude endogenous variables such as quantity demanded it also demonstrates that using utility theoretic models allows one to compare travel cost models and contigent valuation models on the basis of their implied behavior not on the unobservable surplus or variation measure

empathy conditioned conservation walking in the shoes of others as a conservation farmer conservation tillage on farms can improve downstream water quality using a dual interests theoretical framework guided by the metaeconomics approach this paper examines the role of self interest and shared other interest in the conservation tillage adoption decision the data is from a 2007 survey of farmers in the blue river tuttle creek watershed of nebraska and kansas logit models show that farmers who temper their pursuit of self interest with shared other interest reflecting empathy sympathy are more likely to adopt conservation tillage habit and control also play a role farmers pursue a joint and interdependent own interest and not only self interest as presumed in microeconomics

measuring the efficiency of energy intensive industries across european countries abstract this study evaluates the energy efficiency trends of five energy intensive industries in 23 european union eu countries over the period 2000 2009 in particular the performance of the construction electricity manufacturing mining and quarrying and transport sectors is examined the analysis is based on data envelopment analysis dea combined with the malmquist productivity index mpi which allows for distinctions between efficiency and technology changes over time at the second stage of the analysis cross classified multilevel modelling is applied to analyse the main drivers behind efficiency performance using a number of sector and country characteristics based on dea results an overall improvement in efficiency is observed in all sectors over the period the decomposition of the mpi indicates that technology change is primarily responsible for the improvements achieved in most sectors the results obtained by the cross classified model show among other things that the high electricity prices energy taxes and market share of the largest generator in the electricity market have a negative effect on industrial energy efficiency

distinguishing between whole farm vs partial farm participation in the conservation reserve program by distinguishing between the decision to participate in the conservation reserve program crp and the decision for whole farm vs part farm participation we model participation as separate binary decisions our results suggest the farm characteristics and other factors affect the decision to participate in crp differently than the decision regarding whole farm vs part farm participation this model formulation also helps to clarify the conditions under which the effect of crp payments on the acreage enrolled in the program is positive or negative

do landowners respond to land retirement incentives evidence from the conservation reserve enhancement program previous research on incentive responsivness in voluntary land retirement programs has utilized either hypothetical contingent response methods or actual aggregate enrollment data both of which suffer from potential biases in this paper we analyze program participation in the binary choice setting of the conservation reserve enhancement program crep using data from six states our results suggest that landowners react positively to the incentives that are offered and that increases in one time incentives offered at the time of signup are a more cost effective means to increase enrollment than increases in the incentives offered on an annual basis

a multi criteria decision analysis model for carbon emission quota allocation in china s east coastal areas efficiency and equity abstract the allocation of carbon emission quotas is recognized as a fundamental and critical step towards the establishment of an effective nationwide carbon emissions trading cet market in china this paper aims to examine the quota allocation pertaining to china s east coastal areas these regions are pioneers in reformation and the domestic heavy emitters in this paper a multi criteria decision analysis model is proposed this model is based on the principles of efficiency and equity in order to reflect the true efficiency of carbon emissions a weighted russell direction distance model is employed three criteria namely capacity responsibility and potential are used to evaluate the degrees of equity furthermore different situations are set to evaluate the related indicators the results indicate the following 1 industrial provinces have less carbon emission quota increments 2 the yangtze river delta economic zone has notably improved energy efficiency and future quota increments correspond with the zone s current carbon emissions 3 circum bohai sea economic zone will be a major buyer of carbon emission quotas while pan pearl river delta economic zone currently receives surplus quota 4 the overall allocation of quotas converts from uneven to even as a result of gdp growth these results provide a reference for collaborative regional reductions in carbon emissions and for the construction of a cet market

resource allocation based on efficiency analysis the purpose of this paper is to develop an approach to a resource allocation problem that typically appears in organizations with a centralized decision making environment for example supermarket chains banks and universities the central unit is assumed to be interested in maximizing the total amount of outputs produced by the individual units by allocating available resources to them we will develop an interactive formal approach based on data envelopment analysis dea and multiple objective linear programming molp to find the most preferred allocation plan the units are assumed to be able to modify their production in the current production possibility set within certain assumptions various assumptions are considered concerning returns to scale and the ability of each unit to modify its production plan numerical examples are used to illustrate the approach

nonpoint pollution control inducing first best outcomes through the use of threats abstract this paper develops an economic model to analyze the use of a policy that combines a voluntary approach to controlling nonpoint source pollution with a background threat of an ambient tax if the voluntary approach is unsuccessful in meeting a pre specified environmental goal we show that such a policy can be designed to induce cost minimizing abatement without actually imposing the tax because the threat of imposition of the tax is sufficient to induce voluntary compliance thus the combined policy approach can not only be more effective in protecting environmental quality than a pure voluntary approach but can also be less costly than a pure ambient tax approach however whether the cost minimizing choices are a unique equilibrium or not depends on the design of the tax policy and whether or not it can be applied retroactively all results still hold if the background threat takes the form of a reducing in government subsidies

combining contingent valuation and travel cost data for the valuation of non market goods the travel cost method tcm has long been used to infer the economic value of nonmarket resources and public goods more recently contingent valuation cvm survey methods have gained popularity for eliciting these values here cvm survey responses are combined with tcm data on actual market behavior to estimate jointly both the parameters of the underlying utility function and its corresponding ordinary demand function this is a prototypical empirical example of a new modeling strategy variants of which should prove useful in many applications especially where reliance on a single valuation method is undesirable

does a college education cause better health and health behaviours in this article we exploit the recent higher education expansion in china to apply a regression discontinuity method to identify the causal effects of higher education on health and health behaviours we do not find causal effect of a college education on better smoking and drinking behaviours for our selected measures of health we do not find causal effect of a college education on better self assessed health less chance of having illness in the past 3 months and keeping normal body weight however we find that a college education could significantly reduce the probability of having hypertension

health related life cycle risks and public insurance abstract based on a dynamic life cycle model this study analyzes health related risks of consumption and old age poverty the model allows for health effects on employment risks on productivity on longevity the correlation between health risks productivity and preferences and the financial incentives of the german public insurance schemes the estimation uses data on male employees and an extended expectation maximization algorithm simulations suggest that health shocks induce average losses in annual consumption of about 10 and account for more than two thirds of the cases of old age poverty annuity markets that account for differences in the longevity risk by health status can effectively reduce the consumption risks but only slightly decrease old age poverty a policy analysis of minimum pension benefits indicates that a means test mitigates the associated moral hazard problem substantially

the impact of 9 year compulsory education quasi experimental evidence from taiwan using a regression discontinuity design this article investigates the causal impacts of 9 year compulsory education on students educational attainment and dropout rate by taiwan population and ho

health behavior health knowledge and schooling the positive correlation between schooling and good health is well documented one explanation is that schooling helps people choose healthier life styles by improving their knowledge of the relationship between health behaviors and health outcomes that is schooling improves the household s allocative efficiency in producing health this empirical study uses direct measures of health knowledge to test this explanation part of the relationship between schooling and the consumption of cigarettes alcohol and exercise is explained by differences in health knowledge however most of schooling s effects on health behavior remain after differences in knowledge are controlled for

utility consistent discrete continuous choices in soil conservation a utility consistent model of participation and participation intensity choices for a voluntary soil conservation program is developed a modified form of roy s identity is used to derive a two equation system that links the discrete dichotomous choice participation and the continuous choice intensity to the same utility function the model corrects for selectivity bias that arises in single equation approaches an application to a filter strip program in two counties in illinois and michigan demonstrates that different factors affect responses to the program across the sample regions estimated willingness to accept payments for participation in the program suggest policy impacts are not uniform across locations

consumption risk farm characteristics and soil conservation adoption among low income farmers in the philippines abstract this paper investigates patterns of soil conservation adoption among low income farmers in the philippines a model is presented that focuses attention on the role of assets and consumption risk in influencing soil conservation adoption decisions results from a reduced form probit model of adoption are reported these econometric findings indicate that patterns of soil conservation adoption reflect relative risk considerations in addition to farm and household characteristics farm size tenure security labor availability and land quality all exhibit a positive association with soil conservation adoption in contrast controlling on these and other household characteristics the probability of adoption falls as consumption risk rises these results underscore a need for greater sensitivity among policymakers to the role of consumption risk in influencing soil conservation decisions in low income settings

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

cost based modelling of optimal emission quota allocation abstract given that a fixed national emission reduction target could be achieved by imposing emission quotas among multiple decision making units under administration a novel nonlinear programming approach is proposed in this paper to obtain an optimal emission quota allocation in a least cost way marginal emission abatement cost curves are simulated based on the environmental performance and marginal emission abatement costs measured in a set of parametric directional output distance functions with multi inputs and multi outputs further the proposed model is applied to empirically investigate the optimal carbon emission quota allocation for china s building construction industry among thirty three provinces in three different regions the results indicate that the relatively developed eastern region in china has higher marginal emission abatement cost and can be imposed with more emission quotas while the central and western regions can undertake more emission reduction approximately 74 million rmb can be saved by implementing the optimal emission allocation proposed in this paper as compared to a uniform emission quota allocation the findings are of great theoretical methodological and practical significance for policymakers and social science researchers in terms of climate change mitigation

efficient allocation of co2 emissions in china a zero sum gains data envelopment model abstract the appropriate allocation of co 2 emission quotas can build up a solid foundation for future emissions trading building co 2 emissions allocation mechanism has significant practical implications based on radial zero sum gains data envelopment zsg dea allocation model this paper uses a non radial zsg dea model to allocate co 2 emissions between different chinese provinces unlike previous studies treating co 2 as the input variable we treat co 2 as the undesirable output variable the modified model can better reflect macro production process while earlier relevant models treated co 2 emissions as inputs this paper contributes to the existing resource allocation method and allocates china s provincial co 2 emissions from the view of technical efficiency the results of our paper reveal that 1 between 2006 and 2010 the cumulative optimal amounts of co 2 emissions were higher than the actual amounts in 12 provinces and lower in other 18 provinces 2 several energy abundant provinces such as shanxi and inter mongolia need to take more responsibilities in co 2 emissions reduction 3 after the zsg dea allocation all provinces co 2 emissions are on zsg dea frontier which reflects the overall pareto optimality

the relationship between education and adult mortality in the united states prior research has uncovered a large and positive correlation between education and health this paper examines whether education has a causal impact on health i follow synthetic cohorts using successive u s censuses to estimate the impact of educational attainment on mortality rates i use compulsory education laws from 1915 to 1939 as instruments for education the results suggest that education has a causal impact on mortality and that this effect is perhaps larger than has been previously estimated in the literature copyright 2005 wiley blackwell

intergenerational transmission of education and mediating channels evidence from a compulsory schooling reform in germany in this paper i estimate the causal effect that an additional year of schooling for parents has on their children s education by exploiting a compulsory schooling reform that was implemented in all west german states between 1946 and 1969 although previous research indicates that the reform had no effect on earnings i find that an additional year of schooling for women strongly affects the education of their sons there is no effect for the other parent child gender pairs i investigate numerous channels that might mediate the positive effect of the education of mothers most importantly i find that individuals with more schooling value their children s educational success as more important

integrated weighting approach to carbon emission quotas an application case of beijing tianjin hebei region abstract the coordinated development of beijing tianjin hebei region has been included in the chinese 12th five year plan as a national strategy accordingly the cooperation of energy saving and environmental protection is an important part at the present stage establishing carbon emission trading market in china is regarded as an effective measure to reduce and control carbon dioxide emission meanwhile it is an important task for government to allocate carbon emission quotas among regions in order to explore the cross provincial carbon trading market mode of china this paper aims to construct a comprehensive index and use the integrated weighting approach to simulate the carbon quota allocation of beijing tianjin hebei region the results show that firstly the indicator of responsibility which is about 0 56 is given relatively more weight among the three indicators by comparison the weights of capacity and potential are 0 13 and 0 30 secondly the provinces with strong economic ability and lower carbon reduction potential may get fewer proportions of carbon emission quotas such as beijing thirdly since undertaking the function transfer and dispersal of beijing and tianjin hebei should have a relatively high carbon emission quotas in the future carbon trading market these results may provide insightful support for decision makers to promote collaborative carbon reduction and allocate carbon quotas in beijing tianjin hebei region of china

payments for ecosystem services programs predicting landowner enrollment and opportunity cost using a beta binomial model this paper concerns predicting enrollment in payment for ecosystem services pes programs to promote habitat preservation on private lands we develop a beta binomial model to address both program participation and the amount of land enrolled by each potential enrollee we apply the estimation approach to stated preference data from non industrial private forest owners in finland as an alternative econometric model we also develop a multivariate censored regression model of enrollments using cross validation we find that the beta binomial model predicts at least as well as the multivariate censored model yet has fewer parameters using our estimation results we demonstrate policy predictions regarding program enrollment and landowner opportunity cost

does longer compulsory schooling affect mental health evidence from a british reform abstract in this paper we examine whether longer compulsory schooling has a causal effect on mental health exploiting a 1972 reform which raised the minimum school leaving age from age 15 to 16 in great britain using a regression discontinuity design we find that the reform did not improve mental health we provide evidence that extending the duration of compulsory schooling impacts mental health through channels other than increased educational attainment we argue that these effects may mitigate or offset the health returns to increased educational attainment

valuing soil conservation benefits of agroforestry contour hedgerows in the eastern visayas philippines abstract trees can be considered as investments made by economic agents to prevent depreciation of natural assets such as stocks of top soil and water in agroforestry systems farmers use trees in this manner by deliberately combining them with agricultural crops on the same unit of land although advocates of agroforestry have asserted that soil conservation is one of its primary benefits empirical estimates of these benefits have been lacking due to temporal and spatial complexity of agroforestry systems and the nonmarket aspect of soil capital assets this study designs and applies a bio economic framework for valuing the soil conservation benefits of agroforestry the framework is tested with econometric analysis of data from surveys of households in eastern visayas philippines where usaid government of philippines introduced contour hedgerow agroforestry in 1983 by constructing a weighted soil quality index that also incorporates measures of soil fertility texture and color in addition to erosion we extend previous economic studies of soil resources this index is regressed on a variety of farming and site specific bio physical variables next we use a cobb douglas profit function to directly relate agricultural profits and soil quality thus the value of soil conservation is measured as a quasi rent differential or the share of producer surplus associated with a change in soil quality because this framework assumes the existence of markets the assumption is tested by analysing the statistical significance of consumption side variables e g number of household members on production side variables e g profits instrumental variables are used to handle the endogeneity of the soil index in the profit equation seemingly unrelated regression sur analysis is used to accommodate correlation of errors across the soil and profit equations regression results reveal the importance of agroforestry intensity private ownership land fragmentation and familiarity with soil conservation as positive covariates of soil quality analysis of production data indicate the importance of market prices education farming experience farm size topography and soil quality as positive covariates of household profits investments in agroforestry to improve or maintain soil capital can increased annual agricultural profits by us 53 for the typical household which is 6 of total income however there are significant up front costs given that small farmers in tropical uplands are important players in the management of deteriorating soil and forest resources policy makers may want to consider supporting farmers in the early years of agroforestry adoption

pareto improvement through a reallocation of carbon emission quotas abstract this article presents a methodology that discusses a reallocation of carbon emission quotas based on the zsg dea model also introduces the process of solving the zsg dea model in extensive detail and derives theorems 1 and 2 theorem 1 shows the equivalence in competition and the cooperation case while theorem 2 indicates the correlation between quota adjustment and efficiency change through this zsg dea model the determination of carbon emission quotas is no longer subjective and reasonable carbon emission quotas among countries can be obtained the reallocation of carbon emission quotas can not only ensure that all countries have 100 efficiencies but also help all countries gain through pareto improvement the conclusions of this paper are that most developed countries should increase their carbon emission quotas and that most less developed countries need to reduce theirs including the two most populous countries of china and india the reallocation process should be paid by selling the quotas of low efficient countries so that they can obtain funds to support their development while at the same time high efficient countries can produce more due to relaxation of environmental constraints thus achieving global pareto improvement

effect of secondary school fees on educational attainment in this study the heterogeneity of the fee abolition process in west german secondary schools is used to identify the effect of school fees on educational attainment and to obtain an estimate of the price elasticity of upper secondary education the analysis is based on representative individual level data from three annual surveys of the german mikrozensus while coefficients cannot be estimated precisely the results suggest that on average upper secondary school attainment increased by at least 8 percent in response to the fee abolition the educational attainment of females appears to be more price sensitive than that of males

energy consumption for space heating a discrete continuous approach energy demand for space heating is estimated using a discrete continuous choice model which focuses on the relationship between the choice of heating equipment and energy consumption the model is estimated on norwegian micro data and the two stages of the model are estimated simultaneously the capital cost and the operating cost of the heating systems are both found to have a significant impact on the choice of heating system furthermore the results show that household characteristics are important variables in residential energy models energy price elasticities and income elasticities are also estimated

changes in compulsory schooling and the causal effect of education on health evidence from germany in this paper we investigate the causal effect of years of schooling on health and health related behavior in west germany we apply an instrumental variables approach using as natural experiments several changes in compulsory schooling laws between 1949 and 1969 these law changes generate exogenous variation in years of schooling both across states and over time we find evidence for a strong and significant causal effect of years of schooling on long term illness for men but not for women moreover we provide somewhat weaker evidence of a causal effect of education on the likelihood of having weight problems for both sexes on the other hand we find little evidence for a causal effect of education on smoking behavior overall our estimates suggest significant non monetary returns to education with respect to health outcomes and not necessarily with respect to health related behavior

regional allocation of co2 emissions allowance over provinces in china by 2020 the mitigation efforts of china are increasingly important for meeting global climate target since the rapid economic growth of china has led to an increasing share in the world s total co2 emissions this paper sets out to explore the approach for realizing china s national mitigation targets submitted to the unfccc as part of the copenhagen accord that is to reduce the intensity of co2 emissions per unit of gdp by 40 45 by 2020 as well as reducing the energy intensity and increasing the share of non fossil fuel consumption through regional allocation of emission allowance over china s provinces since the realization of china s mitigation target essentially represents a total amount emission allowance allocation problem an improved zero sum gains data envelopment analysis optimization model which could deal with the constant total amount resources allocation is proposed in this study by utilizing this model and based on several scenarios of china s economic growth co2 emissions and energy consumption a new efficient emission allowance allocation scheme on provincial level for china by 2020 is proposed the allocation results indicate that different provinces have to shoulder different mitigation burdens in terms of emission intensity reduction energy intensity reduction and share of non fossil fuels increase

how can china reach its co2 intensity reduction targets by 2020 a regional allocation based on equity and development in late 2009 the chinese government committed to cut its carbon dioxide emissions per unit of gross domestic product gdp by 40 to 45 of 2005 levels by 2020 this has raised the issue of how to allocate the co2 reduction target regionally to meet the national reduction target to meet this objective the following aspects may be taken into consideration equity principles common but differentiated responsibilities intensity reduction target fulfillment and economic difference and reduction potential among provinces this paper selects per capita gdp accumulated fossil fuel related co2 emissions and energy consumption per unit of industrial added value as indicators for emission reduction capacity responsibility and potential respectively based on these three indicators a comprehensive index is developed and an intensity allocation model constructed as decision makers may have different preferences when allocating the reduction burden we allocate different weights to the indicators analyzing the results using cluster analysis the following aspects may also be considered together with the national regional development strategy to determine how to share the burden the reduction potential of various regions implementation potential of the plans and promotion of a highly efficient low carbon economic development model

limiting environmental program contradictions a demand systems application to fishery management economically efficient natural resource policy requires the comprehensive management of environmental improvements over a system of sites use of multisite demand and benefit models can reduce the number and cost of environmental program contradictions in this paper we present a multisite demand model that incorporates several quality dimensions for a system of new mexico fishing sites use of the model permits managers to improve total welfare at lower cost by simultaneously distributing opportunity across all elements in resource users choice sets model results show that errors that result from independently adding values of interdependent program elements approach 50

econometric estimation of technical and environmental efficiency an application to dutch dairy farms in this article we estimate the technical and environmental efficiency of a panel of dutch dairy farms nitrogen surplus arising from the application of excessive amounts of manure and chemical fertilizer is treated as an environmentally detrimental input a stochastic translog production frontier is specified to estimate the output oriented technical efficiency environmental efficiency is estimated as the input oriented technical efficiency of a single input the nitrogen surplus of each farm the mean output oriented technical efficiency is rather high 0 894 but the mean input oriented environmental efficiency is only 0 441 intensive dairy farms are both technically and environmentally more efficient than extensive farms

collateral damage the german food crisis educational attainment and labor market outcomes of german post war cohorts using the german 1970 census to study educational and labor market outcomes of cohorts born during the german food crisis after world war ii i document that those born between november 1945 and may 1946 have significantly lower educational attainment and occupational status than cohorts born shortly before or after several alternative explanations for this finding are tested most likely a short spell of severe undernutrition around the end of the war has impaired intrauterine conditions in early pregnancies and resulted in long term detriments among the affected cohorts this conjecture is corroborated by evidence from austria

exclusionary manipulation of markets for pollution rights abstract strategic price manipulation can affect the distribution of transferable pollution rights across polluters and the efficiency of pollution control efforts prior research has concentrated on market manipulation by firms seeking only to minimize the sum of pollution rights costs and pollution abatement costs in this paper we explore the potential for the exclusionary manipulation of pollution permit markets intended to drive up the costs of one s rivals and we distinguish between the resource allocation effects of exclusionary manipulation and cost minimizing manipulation we find that exclusionary manipulation can sometimes worsen and sometimes ameliorate the abatement inefficiency which occurs under cost minimizing manipulation and that an overbuying rule can obviate or at least limit damages from this form of strategic behavior

allocating fixed costs and resources via data envelopment analysis abstract in this paper we show that data envelopment analysis dea can be viewed as maximising the average efficiency of the decision making units dmus in an organisation building upon this we present dea based models for a allocating fixed costs to dmus and b allocating input resources to dmus simultaneous to allocating input resources output targets are also decided for each dmu numeric results are presented for a number of example problems taken from the literature

kyoto and carbon leakage an empirical analysis of the carbon content of bilateral trade abstract has the kyoto protocol induced carbon leakage we conduct the first empirical ex post evaluation of the protocol we derive a theoretical gravity equation for the carbon dioxide content of trade which accounts for intermediate inputs both domestic and imported the structure of our new panel database of the carbon content of sectoral bilateral trade flows allows controlling for the endogenous selection of countries into the kyoto protocol binding commitments under kyoto have increased committed countries embodied carbon imports from noncommitted countries by around 8 and the emission intensity of their imports by about 3 hence kyoto has indeed led to leakage

allocation of carbon dioxide emission permits with the minimum cost for chinese provinces in big data environment abstract the environmental problem and global warming have drawn many governments attention in order to solve the problem reasonable allocation of carbon dioxide emission cde permits is an important issue because it sets the targets for the decision making units to control the amount of carbon dioxide emission in this paper a new data envelopment analysis approach is proposed to evaluate the efficiency of decision making units in a big data environment and set the carbon dioxide emission permits for each decision making unit with the minimum costs comparing with the previous works on carbon dioxide emission permits allocation we firstly allocate the amount of carbon dioxide emission permits taking account into the cost each decision making unit should take to achieve its target moreover two kinds of linear programming problems are developed under efficiency invariance principle and efficiency changeability principle respectively as the allocation of carbon dioxide emission permits causes the minimum cost the decision making units are more easily to accept the allocation alternative finally our approach is applied to the carbon dioxide emission permits allocation among chinese provinces the results show that the approach can well allocate the cde permits with the minimum cost and also reveal the relationship between the marginal cost of reducing cde permits and the adjustment on them

olympic ranking based on a zero sum gains dea model abstract it is usual to rank the participant countries in the olympic games in accordance with the number of medals they have won an alternative ranking is suggested in this paper this ranking is based on each country s ability to win medals in relation to its available resources this is an efficiency that can be measured with the help of data envelopment analysis dea for which two models exist the traditional dea model that takes into account variable returns to scale and a dea model based on the premise that the sum of the gains is zero constant sum of outputs it is the latter that is developed in this paper

market power and transferable property rights the appeal of using markets as a means of allocating scarce resources stems in large part from the assumption that a market will approximate the competitive ideal when competition is not a foregone conclusion the question naturally arises as to how a firm might manipulate the market to its own advantage this paper analyzes the issue of market power in the context of markets for transferable property rights first a model is developed that explains how a single firm with market power might exercise its influence this is followed by an examination of the model in the context of a particular policy problem the control of particulate sulfates in the los angeles region

an economy of scales a selective review of obesity s economic causes consequences and solutions this paper reviews the economic research on obesity covering topics such as the measurement of and trends in obesity the economic causes of obesity e g the monetary price and time cost of food food assistance programs income education macroeconomic conditions and peer effects and the economic consequences of obesity e g lower wages a lower probability of employment and higher medical care costs it also examines the extent to which obesity imposes negative externalities and economic interventions that could potentially internalize such externalities such as food taxes subsidies for school based physical activity programs and financial rewards for weight loss it discusses other economic rationales for government intervention with respect to obesity such as imperfect information time inconsistent preferences and irrational behavior it concludes by proposing a research agenda for the field overall the evidence suggests that there is no single dominant economic cause of obesity a wide variety of factors may contribute a modest amount to the risk there is consistent evidence regarding the economic consequences of obesity which are lower wages and higher medical care costs that impose negative externalities through health insurance studies of economic approaches to preventing obesity such as menu labeling taxes on energy dense foods and financial rewards for weight loss find only modest effects on weight and thus a range of policies may be necessary to have a substantial effect on the prevalence of obesity

zero returns to compulsory schooling in germany evidence and interpretation abstract we estimate the impact of compulsory schooling on earnings using changes in compulsory schooling laws in west germany after world war ii most estimates in the literature indicate returns in the range of 10 to 15 while our research design is very similar to studies for various other countries we find a zero return we find no evidence that this is due to labor market institutions or the apprenticeship training system in germany the result might be due to the fact that the basic skills most relevant for the labor market are learned earlier in germany than in other countries

efficiency and allocation of emission allowances and energy consumption over more sustainable european economies abstract efficient use of energy reduction in fossil fuel dependence and control of co2 emissions are all fundamental to development of a sustainable economy competitiveness in energy use saves imports of oil and gas increases gross domestic product and creates new jobs in the renewable energy and energy efficiency sectors this study identifies the more or less competitive european union member states in terms of sustainable growth using data envelopment analysis dea model and proposes new allocations of country greenhouse gas limits and energy consumption using a zero sum gains dea model the analysis of european countries fills a gap in the existing literature and contributes to the discussion on the 2020 2030 european strategy proposing an efficiency based indicator which measures country performance in terms of economic social and environmental factors gdp represents the economic factor population represents the social factor and emissions final and renewable energy consumption are the environmental factors the numerical results show that the initial allocations are inefficient applying the modelled reallocation the most efficient countries are rewarded by potential increases in emission and energy consumption while the least efficient countries must bring about decreases to achieve full efficiency

a dea approach for estimating the agricultural energy and environmental efficiency of eu countries this study attempts to evaluate the energy and environmental efficiency of the primary sectors of the eu member state countries the evaluation is based on a non radial data envelopment analysis dea model which allows for non proportional adjustments to energy inputs and undesirable outputs and thus it provides different estimations for energy and environmental efficiency scores the 2001 2008 time period was selected for this research one of the most important findings is that countries like germany sweden or austria with strong environmental protection standards appear to be less energy and environmentally efficient compared with countries like denmark belgium spain france or ireland in addition a series of eastern european countries achieve low efficiency scores which can be characterized as expectable due to low technology level being implemented in the primary production process there are also two sub periods for this research the first one 2001 2006 covers the fully coupled with specific cultivations period for subsidy administation and the second 2007 2008 where the new decoupled subsidy scheme was implemented there are significant hints for considerable changes of energy and environmental efficiency after the implementation of the the new cap with the new member states siginificantly differ of both energy and environmental efficiency copmared with the older ones

a preliminary analysis of texas ranchers willingness to participate in a brush control cost sharing program to improve off site water yields abstract brush cover of 30 is estimated to be economically optimal for ranches on the edwards plateau texas this contrasts with a regional objective to increase off site water yield which is maximized if brush cover is removed survey research was conducted to assess ranchers willingness to enter a 10 year easement contract to clear brush to 3 for a fixed cost share payment to offset their opportunity costs of participation sixty six percent of the 119 ranchers surveyed were willing to enroll ranch size income from livestock and deer hunting enterprises and perceptions about brush control costs were important explanatory variables in statistical analysis using probit and cragg models

estimating average and local average treatment effects of education when compulsory schooling laws really matter the change to the minimum school leaving age in the united kingdom from 14 to 15 had a powerful and immediate effect that redirected almost half the population of 14 year olds in the mid twentieth century to stay in school for one more year the magnitude of this impact provides a rare opportunity to a estimate local average treatment effects late of high school that come close to population average treatment effects ate and b estimate returns to education using a regression discontinuity design instead of previous estimates that rely on difference in differences methodology or relatively weak instruments comparing late estimates for the united states and canada where very few students were affected by compulsory school laws to the united kingdom estimates provides a test as to whether instrumental variables iv returns to schooling often exceed ordinary least squares ols because gains are high only for small and peculiar groups among the more general population i find instead that the benefits from compulsory schooling are very large whether these laws have an impact on a majority or minority of those exposed

schooling health knowledge and obesity the connection between schooling and health is well documented an important empirical issue that needs to be examined however is whether schooling s effects are due to individual health knowledge differences this empirical study examines this issue with an increasingly important health indicator obesity since provision of health knowledge is a major tool of public agencies promoting health this empirical study uses a new direct measure of health knowledge to test this hypothesis the results show that knowledge is inversely related to the probability that an individual is obese schooling s effects on relative weight and the probability of being obese are explained by differences in knowledge this result may imply that schooling s effect on the allocative efficiency of the household production of health is the main reason schooling is linked to health behaviour the result also may imply that the most effective method of health education is to highlight the disease element of poor dietary habits a

voluntary environmental agreements good or bad news for environmental protection abstract there has been growing interest in the use of voluntary agreements vas as an environmental policy tool this article uses a simple model to determine whether vas are likely to lead to efficient environmental protection we consider cases where polluters are induced to participate either by a background threat of mandatory controls the stick approach or by cost sharing subsidies the carrot approach the results suggest that the overall impact on environmental quality could be positive or negative depending on a number of factors including the allocation of bargaining power the magnitude of the background threat and the social cost of funds

a more scientific allocation scheme of carbon dioxide emissions allowances the case from china abstract efficient allocation of carbon dioxide co2 emissions allowances is essential to the realization of the emissions reduction goal using china as an example this study applies a zero sum gains data envelopment analysis zsg dea model to translate the country s reduction target into provincial goals based on the chinese government s 2020 reduction goal to evaluate efficiency scores we employ the epsilon based measure model that combines radial and non radial characteristics different from prior studies we emphasize the effect of industrial structure on co2 emissions and calculate a composite gross domestic product gdp index as one of the output variables by utilizing the zsg dea model and based on china s provincial co2 emissions allowances as the input variable the composite gdp index and the population as the output variable we obtain an optimal reallocation scheme after four iterations a comparison between the results and official reduction goals shows that the government should increase co2 emissions allowances appropriately for most provinces with high proportions more than 40 of second industry increment in gdp thereby carrying implications for policymakers with china as an example these findings have global implications as regards developing a more scientific allocation scheme especially for regions with unbalanced industrial structures
