assessing income population and technology impacts on co2 emissions in canada where s the ekc abstract this study investigates the macroeconomic forces underlying carbon dioxide co2 emissions from fossil fuel use in canada in keeping with the relevant literature on environmental degradation three forces are expected to influence co2 emissions gross domestic product per capita gdp capita population and technological change while previous work has employed reduced form models that allow for non linear relationships between co2 and gdp capita it has been common practice to assume linear relationships between co2 and the latter two variables this study tests a more flexible model using a five region panel data set in canada over the period 1970 2000 findings indicate that gdp capita is unrelated to co2 that an inverted u shaped relationship exists with population and that a u shaped relationship exists with technology thus technological and population changes are supported over the commonly hypothesized environmental kuznets curve an inverted u shaped relationship between gdp capita and environmental degradation for affecting co2 emissions from fossil fuel use in canada

estimating the benefits of farm animal welfare legislation using the contingent valuation method abstract this paper presents the method and findings of a contingent valuation cv study that aimed to elicit united kingdom citizens willingness to pay to support legislation to phase out the use of battery cages for egg production in the european union eu the method takes account of various biases associated with the cv technique including warm glow part whole and sample response biases estimated mean willingness to pay to support the legislation is used to estimate the annual benefit of the legislation to uk citizens this is compared with the estimated annual costs of the legislation over a 12 year period which allows for readjustment by the uk egg industry the analysis shows that the estimated benefits of the legislation outweigh the costs the study demonstrates that cv is a potentially useful technique for assessing the likely benefits associated with proposed legislation however estimates of cv studies must be treated with caution it is important that they are derived from carefully designed surveys and that the willingness to pay estimation method allows for various biases

does income inequality harm the environment empirical evidence from the united states abstract this study revisits the growth inequality environment nexus in the context of country specific time series data the short and long run effects of income inequality economic growth and energy consumption on co2 emissions in the u s are examined using the autoregressive distributed lag ardl approach we find that more equitable distribution of income in the u s results in better environmental quality in the short and long run it is also found that in both the short and long run economic growth has a beneficial effect on environmental quality whereas energy consumption has a detrimental effect on the environment

economic growth and pollutant emissions in tunisia an empirical analysis of the environmental kuznets curve abstract this paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country tunisia during the period 1961 2004 the investigation is made on the basis of the environmental kuznets curve hypothesis using time series data and cointegration analysis carbon dioxide co 2 and sulfur dioxide so 2 are used as the environmental indicators and gdp as the economic indicator our results show that there is a long run cointegrating relationship between the per capita emissions of two pollutants and the per capita gdp an inverted u relationship between so 2 emissions and gdp has been found with income turning point approximately equals to 1200 constant 2000 prices or to 3700 in ppp constant 2000 prices however a monotonically increasing relationship with gdp is found more appropriate for co 2 emissions furthermore the causality results show that the relationship between income and pollution in tunisia is one of unidirectional causality with income causing environmental changes and not vice versa both in the short run and long run this implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth it could be a feasible policy tool for tunisia to achieve its sustainable growth in the long run

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

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

consumers willingness to pay for the color of salmon a choice experiment with real economic incentives in most retail markets sellers post the price and consumers choose which products to buy we designed an experimental market with posted prices to investigate consumers willingness to pay for the color of salmon salmon fillets varying in color and price were displayed in twenty choice scenarios in each scenario the participants chose which of two salmon fillets they wanted to buy to induce real economic incentives each participant drew one binding scenario the participants then had to buy the salmon fillet they had chosen in their binding scenario the choice data were analyzed with a mixed logit model

is income inequality a driver for renewable energy consumption abstract although many initiatives have been made to research the effect of income inequality on environmental issues the question of whether income inequality affects renewable energy consumption hasn t been answered this gap in the literature raises an important question that needs to be answered by researchers can the income inequality affect renewable energy consumption as far as is known the study is the first attempt to discover this relationship therefore the impact of income inequality on renewable energy consumption is examined theoretically and empirically in 43 developed and developing countries for 2000 2015 in order to avoid the omitted variable problem economic environmental and institutional variables such as gdp per capita corruption co2 emissions and trade openness are included in the model the results demonstrate that the decline in income inequality will enhance renewable energy consumption in other words policymakers have the opportunity to reduce income inequality and environmental degradation at the same time similarly corruption control and raise co2 emissions will increase also renewable energy consumption otherwise economic determinants such as economic growth and trade openness have no meaningful effect on renewable energy consumption

incentive aligned conjoint analysis abstract because most conjoint studies are conducted in hypothetical situations with no consumption consequences for the participants the extent to which the studies are able to uncover true consumer preference structures is questionable experimental economics literature with its emphasis on incentive alignment and hypothetical bias suggests that more realistic incentive aligned studies result in stronger out of sample predictive performance of actual purchase behaviors and provide better estimates of consumer preference structures than do hypothetical studies to test this hypothesis the authors design an experiment with conventional hypothetical conditions and parallel incentive aligned counterparts using chinese dinner specials as the context the authors conduct a field experiment in a chinese restaurant during dinnertime the results provide strong evidence in favor of incentive aligned choice conjoint analysis in that incentive aligned choice conjoint outperforms hypothetical choice conjo

operational research in education operational research or techniques have been applied from the early stages of the discipline to a wide variety of issues in education at the government level these include questions of what resources should be allocated to education as a whole and how these should be divided amongst the individual sectors of education and the institutions within the sectors another pertinent issue concerns the efficient operation of institutions how to measure it and whether resource allocation can be used to incentivise efficiency savings local governments as well as being concerned with issues of resource allocation may also need to make decisions regarding for example the creation and location of new institutions or closure of existing ones as well as the day to day logistics of getting pupils to schools issues of concern for managers within schools and colleges include allocating the budgets scheduling lessons and the assignment of students to courses this survey provides an overview of the diverse problems faced by government managers and consumers of education and the or techniques which have typically been applied in an effort to improve operations and provide solutions

are choice experiments incentive compatible a test with quality differentiated beef steaks this study compares hypothetical and nonhypothetical responses to choice experiment questions we test for hypothetical bias in a choice experiment involving beef ribeye steaks with differing quality attributes in general hypothetical responses predicted higher probabilities of purchasing beef steaks than nonhypothetical responses thus hypothetical choices overestimate total willingness to pay for beef steaks however marginal willingness to pay for a change in steak quality is in general not statistically different across hypothetical and actual payment settings

does income inequality facilitate carbon emission reduction in the us abstrct considering the short and long term impacts of income inequality on carbon emissions as well as the heterogeneity of the emission distribution this paper employs panel ardl and quantile regression models to analyze the effect of income inequality on carbon emissions across us states the findings suggest that higher income inequality increases us carbon emissions in the short term whereas it promotes carbon reduction in the long term furthermore we find that the absolute values for the coefficients on income inequality in the states from the 70th to the 90th quantiles are larger than those from the 10th to the 40th quantiles this indicates that income inequality reduces more carbon emissions in states with higher per capita carbon emissions the results provide important insights for policy makers to improve the quality of economic development and address climate change

reducing inequalities toward the development of a market for income inequality abstract the objective of this study is to propose the development of a market for income inequality by specifying a firm s contribution to income inequality and outlining a simple model to find the equilibrium price for a given target of income inequality reduction the paper reviews the concepts of firm heterogeneity and externalities in relation to income inequality it then proposes a model by establishing income inequality reduction targets for a population of firms presenting a marginal income inequality reduction cost curve and matching demand and supply to derive the equilibrium price and ends by simulating a market for income inequality reduction using data from a sample of fifteen firms this paper shifts the focus of income inequality research and policy to the firm and proposes a market based mechanism for firms to reduce income inequality

what experimental protocol influence disparities between actual and hypothetical stated values preferences elicited in hypothetical settings have recently come underscrutiny causing estimates from the contingent valuation method to bechallenged due to perceived hypothetical bias given that the receivedliterature derives value estimates using heterogeneous experimentaltechniques understanding the effects of important design parameters onthe magnitude of hypothetical bias is invaluable in this paper we addressthis issue statistically by using a meta analysis to examine data from 29experimental studies our empirical findings suggest that on averagesubjects overstate their preferences by a factor of about 3 in hypotheticalsettings and that the degree of over revelation is influenced by thedistinction between willingness to pay and willingness to accept publicversus private goods and several elicitation methods

anticipating the consequences of school reform a new use of dea we use dea type linear programming techniques to simulate a basic component of educational reform eliminating restrictions on the allocation of school personnel our technique allows us to identify potential output gains or equivalently potential cost savings from reform we can also identify which personnel groups are likely to gain and lose under this reform when we apply our model to a sample of texas school districts we find evidence that the educational establishment has substantial economic rents to protect from school reform and that the primary beneficiaries of reform are likely to be affluent school districts with few minority students the technique which relies on the relationship between the direct and indirect distance functions can be easily generalized to measure the potential gains from removing other input restrictions such as union work rules environmental regulations or deed restrictions

the impact of economic development and social political factors on ecological footprint a panel data analysis for 15 mena countries abstract this paper extends the work of al mulali and ozturk 2015 1 by re investigating the environment kuznets curve ekc hypothesis for 15 mena middle east and north african countries using the ecological footprint ef as a proxy of environmental degradation over the period 1975 2007 unlike the existing studies we augment the basic ekc relationship by considering life expectancy at birth fertility rate and political institutional index variables as new possible determinants of environmental degradation the estimation of this relationship has been conducted for all mena 15 countries for oil exporting and non oil exporting countries sub samples the results show that energy use worsens ecological footprint whereas real gdp per capita exhibits an inverted u shaped relationship with ef in oil exporting countries and in the sample as a whole i e the ekc hypothesis is validated for the non oil exporting countries the relationship between ef and economic growth is u shaped moreover our findings show that socio demographic variables such as urbanization life expectancy at birth and fertility rate improve the environment in the long term we also found that the improvement of political institutions in those countries has not been accompanied by a reduction of environmental stress the granger causality results support evidence of the existence of an error correction mechanism between the ef real gdp energy use and the fertility rate specifically in the short term we found strong evidence for bidirectional causality among the ecological real gdp and energy use variables

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

how closely do hypothetical surveys and laboratory experiments predict field behavior we compare the ability of three preference elicitation methods hypothetical choices nonhypothetical choices and nonhypothetical rankings and three discrete choice econometric models the multinomial logit mnl the independent availability logit ial and the random parameter logit rpl to predict actual retail shopping behavior in three different product categories ground beef wheat flour and dishwashing liquid overall we find a high level of external validity our specific results suggest that the nonhypothetical elicitation approaches especially the nonhypothetical ranking method outperformed the hypothetical choice experiment in predicting retail sales we also find that the rpl can have superior predictive performance but that the mnl predicts equally well in some circumstances experiment

ekc analysis for studying economic growth and environmental quality a case study in china compared with the extensive research on the relationship between economic growth and environmental quality in developed countries there is a paucity of an empirical research on studying the relation for developing countries based upon the environmental kuznets curve ekc theory this paper develops regression models for investigating the relationship between economic growth and environmental quality in china the ekc analysis based on six pollution indices is illustrated with a case study in jiaxing of zhejiang china

inequality and growth in the united states evidence from a new state level panel of income inequality measures i introduction rising income inequality in the united states over the past quarter century is well documented see e g gottschalk 1997 krueger 2003 levy and murnane 1992 piketty and saez 2003 whether and by how much this change in inequality is associated with a change in economic performance is an important question yet recent empirical work has been largely inconclusive positive relationships between income inequality and economic growth have been found by partridge 1997 2005 using a panel of states and by forbes 2000 using a panel of countries empirical work by panizza 2002 and quah 2001 however has found little or no stable relationship between inequality and growth the results appear to be extremely sensitive to the econometric specification additionally barro 2000 has found evidence that the relationship is nonlinear with inequality being positively related to growth among wealthier countries like the united states but negatively related to growth among low income countries much of this recent empirical literature was initiated by the important work of deininger and squire 1996 who constructed a large cross national panel of inequality measures containing several time series observations for each nation spaced over multiple decades a parallel empirical literature also emerged using u s state level data with income inequality measures typically spaced at 10 yr intervals see e g panizza 2002 partridge 1997 2005 both the state level and the cross national empirical literatures benefited by exploiting the more advanced panel data econometrics afforded by the large n small t panel dimensions in this paper we offer a new more comprehensive panel of state level income inequality measures and use this panel to reevaluate the empirical inequality growth relationship 1 this panel has the unique feature of being large in both n and t with annual observations of the 48 contiguous states for the entirety of the postwar period 1945 2004 for nearly all the states in the panel the share of income held by the top decile experienced a prolonged period of stability after world war ii followed by a substantial increase during the 1980s and 1990s these state level trends appear to closely replicate the overall trends in aggregate u s inequality found by piketty and saez 2003 exploiting the large and balanced size of our inequality panel we explore the long run relationship between inequality and growth via three alternative dynamic panel error correction estimators the fixed effects fe estimator the mean group mg estimator of pesaran and smith 1995 and the pooled mg estimator of pesaran shin and smith 1999 the greater homogeneity of state level data helps mitigate the difficulty in adequately capturing structural differences across international panels of earlier studies such as forbes 2000 and barro 2000 corruption levels labor market flexibility tax neutrality tradition of entrepreneurship and many other factors are only poorly measured if at all barro 2000 1011 and these sources of heterogeneity are much more likely to contribute to omitted variable bias across countries than across states the results from our analysis indicate that the long run relationship between the top decile share of income and economic growth is positive in nature moreover an evaluation of several alternative income inequality measures suggests that this positive relationship is driven primarily by the concentration of income in the upper end of the income distribution the structure of the paper is as follows section ii presents the new panel of annual state level inequality measures and includes an important discussion of its key limitations section iii then offers an empirical investigation on the impact of income inequality on the growth rate of real income per capita finally section iv offers a brief set of conclusions

environmental kuznets curve for carbon emissions in pakistan an empirical investigation this study investigates the relationship between carbon emissions income energy consumption and foreign trade in pakistan for the period 1972 2008 by employing the johansen method of cointegration the study finds that there is a quadratic long run relationship between carbon emissions and income confirming the existence of environmental kuznets curve for pakistan moreover both energy consumption and foreign trade are found to have positive effects on emissions the short run results have however denied the existence of the environmental kuznets curve the short run results are unique to the existing literature in the sense that none of the long run determinants of emissions is significant the contradictory results of short and long run give policy makers the opportunity to formulate different types of growth policies for the two terms taking environmental issues into consideration in addition the uni directional causality from growth to energy consumption suggests that the policy makers should not only focus on forecasting future demand for energy with different growth scenarios but also on obtaining the least cost energy furthermore the absence of causality from emissions to growth suggests that pakistan can curb its carbon emissions without disturbing its economic growth

do hypothetical and actual marginal willingness to pay differ in choice experiments application to the valuation of the environment abstract in this paper we test the validity of choice experiments with donations for environmental projects in particular we test whether or not there are differences in preferences between a hypothetical and an actual choice experiment our experiments indicate no differences in addition internal tests of validity indicate transitive and stable preferences in both experiments although there are some indications of possible learning effects during the experiment

investigating environmental kuznets curve in china aggregation bias and policy implications abstract aggregation bias may lead to a wrongly estimated environmental kuznets curve ekc and misguide the policy makers this paper aims to test the existence of aggregation bias in the environmental kuznets curve with the sulfur dioxide so2 emission the empirical methods robust to cross sectional dependence and slope heterogeneity reveals that the estimation of so2 ekc in china suffers from aggregation bias the results with the disaggregate data cannot support the ekc estimated at the aggregate level the finding of aggregation bias has several policy implications first the government should not be misled by the false relationship between the pollutant emission and the real gdp per capita at the aggregate level second the local governments should play more important roles in making environmental protection policies since the more disaggregate data can mitigate the aggregation bias to provide enough incentives to the local government the chinese national government should align the interests of the local governments with those of the national government on the other hand the findings indicate that china can stick to the policy of encouraging foreign direct investment openness and financial development since they have not influenced the so2 emission in china

comparing open ended choice experiments and experimental auctions an application to golden rice we use two experimental valuation methods to estimate consumer demand for genetically modified golden rice the first is an open ended choice experiment oece where participants name the quantities of golden rice and conventional rice demanded at each of several price combinations one of which will be randomly chosen as binding this allows us to estimate market demand by aggregating demand across participants this estimate of market demand also allows us to estimate own price elasticity and consumer surplus for golden rice comparing willingness to pay wtp estimates from the oece with those from a uniform price auction we find that oece wtp estimates exhibit less affiliation across rounds and the effects of positive and negative information under the oece are more consistent with prior expectations and existing studies we also find that while auction wtp estimates more than double across five rounds oece wtp estimates are stable across rounds and are always roughly equal to those from the final auction round

an incentive compatible conjoint ranking mechanism a simple method for making ranking based conjoint analysis incentive compatible is proposed the incentive compatible mechanism involves people purchasing a product profile with a probability proportional to its assigned rank in an empirical application related to consumer preferences for beef attributes we find that the forecasted market share for a new pasture raised steak obtained using incentive compatible rankings was significantly greater than that implied from traditional hypothetical conjoint rankings people s rankings of ground beef products were not affected by the mechanism or by information about pasture raised beef copyright 2008 oxford university press

combining the assumptions of variable and constant returns to scale in the efficiency evaluation of secondary schools our paper reports on the use of data envelopment analysis dea for the assessment of performance of secondary schools in malaysia during the implementation of the policy of teaching and learning mathematics and science subjects in the english language ppsmi the novelty of our application is that it makes use of the hybrid returns to scale hrs dea model this combines the assumption of constant returns to scale with respect to quantity inputs and outputs teaching provision and students and variable returns to scale vrs with respect to quality factors attainment levels on entry and exit and socio economic status of student families we argue that the hrs model is a better informed model than the conventional vrs model in the described application because the hrs technology is larger than the vrs technology the new model provides a tangibly better discrimination on efficiency than could be obtained by the vrs model to assess the productivity change of secondary schools over the years surrounding the introduction of the ppsmi policy we adapt the malmquist productivity index and its decomposition to the case of hrs model

the trade off between income inequality and carbon dioxide emissions abstract we investigate the theoretically ambiguous link between income inequality and per capita carbon dioxide emissions using a panel data set that is substantially larger in both regional and temporal coverage than those used in the existing literature using an arguably superior group fixed effects estimator we find that the relationship between income inequality and per capita emissions depends on the level of income we show that for low and middle income economies higher income inequality is associated with lower carbon emissions while in upper middle income and high income economies higher income inequality increases per capita emissions the result is robust to the inclusion of plausible transmission variables

the political economy of the paris agreement income inequality and climate policy abstract we empirically assess how both between country inequality and within country inequality relate to climate policy ambition as defined by ndc pledges of the paris agreement cop21 we exploit the difference between high and low ambition targets submitted by parties to construct a climate policy ambition index we find that both inequalities shape countries pledges first low income countries tend to be more ambitious in setting their pledges when external support is received second within country inequality is associated with i lower mitigation ambition in low and middle low income countries and with ii higher mitigation ambition although non statistically significant for upperhigh and high income countries our results are discussed in terms of i climate policy being a superior good in rich countries and ii elites benefiting from emitting economic activities in poorer countries

a parallel production frontiers approach for intertemporal efficiency analysis the case of taiwanese commercial banks abstract a comparison of the efficiency of a production unit at one period with those of other units at another period is challenging because the bases for calculating efficiency are usually different the malmquist productivity index mpi is an effective measure that can overcome this difficulty however the existing measures of this index have various weaknesses with regard to feasibility circularity decomposability and consistency this paper thus develops a model to construct parallel production frontiers for the units at different periods to measure the mpi this model is always feasible the calculated mpi has the property of circularity it can be decomposed into the product of efficiency change and technical change and the results are consistent an application of this model to taiwanese commercial banks for the period 2008 2013 confirms these merits the results also indicate that in general the mpis of these banks increased from 2008 to 2013 and this was attributed to improvements in technology since the efficiencies measured from the parallel model are comparable among different units and different periods they can be used for intertemporal analysis to identify the banks with unsatisfactory performance in different periods

identifying the impacts of income inequality on co2 emissions empirical evidences from oecd countries and non oecd countries abstract the emergence of environmental quality challenges is rooted in social problems which mainly come from income inequality and power gap income inequality and climate change have been highlighted as hindering the achievement of sustainable development and environmental protection globally though existing literature has estimated the influences of income inequality on co2 emissions relatively little is known about the long run and short run effects from a cross national perspective therefore the aim of this study is to shed light on the long run and short run relationships between income inequality and per capita co2 emissions based on balanced country level panel dataset for 78 countries from 1990 to 2017 in order to understand how a country s economic level affects the link between inequality and co2 emissions this study classified the sample countries into three groups oecd countries low income non oecd countries and high income non oecd countries the fmols and dols model is applied to examine the relationship between the income inequality and per capita co2 emission meanwhile the estimates of an ardl model revealed the long run and short run effects our empirical results indicate that there is a long term cointegration relationship between income inequality and per capita co2 emissions higher income inequality promotes emission reductions in oecd countries and high income non oecd countries while the influences are insignificant in low income non oecd countries in the long run per capita income carbon intensity population size and urbanization were also considered in this study the estimates of an ardl model indicate that whilst income inequality does not have a significant impact on co2 emissions in the short run per capita national income positively affects co2 emissions meaning that income growth will accelerate emissions carbon intensity positively affects co2 emissions in the long term indicating that increased income facilitates increased energy use and emissions but that progress in co2 recycling technology may ultimately reduce emissions neither population size nor urbanization rate exerted any obvious effects on per capita co2 emissions from a policy perspective governments have an onerous task ahead of them in balancing economic efficiency and distributary justice lastly we provide insights for policy makers that in order to realize the goal of emission reductions in the long run it may be best to proceed by making reasonable national income redistribution policies and by adjusting the welfare system

are valuations from nonhypothetical choice experiments different from those of experimental auctions due to the importance of comparability and external validity of results nonhypothetical experimental methods are increasingly used to elicit consumers willingness to pay for various goods two of the increasingly popular preference elicitation methods are the nonhypothetical choice experiments and experimental auctions we conduct experiments to compare willingness to pay estimates elicited from both methods our results generally suggest that valuations elicited from experimental auctions can differ from those obtained from nonhypothetical choice experiments copyright 2011 oxford university press

bounds testing approach to analysis of the environment kuznets curve hypothesis abstract this paper examines the long run and the dynamic temporal relationships between economic growth energy consumption population density trade openness and carbon dioxide co 2 emissions in brazil china egypt japan mexico nigeria south korea and south africa based on the environment kuznets curve ekc hypothesis we employ the ardl bounds test to cointegration and cusum and cusumsq tests to ensure cointegration and parameter stability the estimated results show that the inverted u shaped ekc hypothesis holds in japan and south korea in the other six countries the long run relationship between economic growth and co 2 emissions follows an n shaped trajectory and the estimated turning points are much higher than the sample mean in addition the results indicate that energy consumption granger causes both co 2 emissions and economic growth in all the countries our results are consistent with previous studies that show that there is no unique relationship between energy consumption population density economic growth trade openness and the environment across countries

economic growth and co2 emissions in malaysia a cointegration analysis of the environmental kuznets curve this paper attempts to establish a long run as well as causal relationship between economic growth and carbon dioxide co2 emissions for malaysia using data for the years from 1980 to 2009 the environmental kuznets curve ekc hypothesis was tested utilizing the auto regressive distributed lag ardl methodology the empirical results suggest the existence of a long run relationship between per capita co2 emissions and real per capita gross domestic product gdp when the co2 emissions level is the dependent variable we found an inverted u shape relationship between co2 emissions and gdp in both short and long run thus supporting the ekc hypothesis the granger causality test based on the vector error correction model vecm presents an absence of causality between co2 emissions and economic growth in the short run while demonstrating uni directional causality from economic growth to co2 emissions in the long run

the income inequality and carbon emissions trade off revisited abstract this paper investigates the marginal effect of income inequality on carbon emissions per capita we use a panel consisting of 68 countries over a 50 year period from 1961 to 2010 we report estimates that support the hypothesis that there is a trade off between carbon emissions per capita and income inequality this trade off is not homogeneous across countries and depends upon the level of development measured by income per capita using panel smooth transition regression we find that this relationship is negative for countries with low to moderate income per capita but becomes slightly positive after passing a threshold located around fifteen thousand 2011 us dollars moreover the inequality elasticity of emissions per capita is comparable in magnitude to its income elasticity therefore both inequality and income levels are crucial to define policies to reduce carbon emissions this implies a challenge to policymakers who pursue to reduce both income inequality and carbon emissions

re examining the environmental kuznets curve hypothesis in the economic community of west african states a panel quantile regression approach abstract this study investigates the validity of the environmental kuznets curve ekc hypothesis for six west african countries over 1970 2017 while using human capital and biocapacity as additional determinants of carbon emissions it uses the panel quantile regression method that provides robust results in case the classical econometric assumptions fail the empirical results revealed that a u shaped relationship between economic growth and carbon dioxide co2 emissions holds in the low middle and high emissions countries as opposed to the inverted u shaped ekc hypothesis trade openness reduces environmental performance in low emission countries financial development has mixed impacts on co2 emissions across the quantiles while financial development enhances environmental quality in the low emissions countries it exerts a detrimental impact in the middle and high emissions countries human capital has significantly positive effects on the lower middle and upper quantiles the obtained results highlight the need for raising environmental awareness and promoting green r d in addition relevant incentives are required to redirect private credits towards green projects and renewable energy development

the becker degroot marschak mechanism is not necessarily incentive compatible even for non random goods abstract this paper uses results from karni e safra z 1987 preference reversals and the observability of preferences by experimental methods econometrica 55 675 685 and karni e 1989 generalized expected utility analysis of multivariate risk aversion international economic review 30 297 305 to show that the becker degroot marschak mechanism is not always incentive compatible even when the item to be valued involves no uncertainty contrary to several recent assertions

the impact of urbanization on co2 emissions evidence from developing countries abstract this paper analyzes the impact of urbanization on co2 emissions in developing countries from 1975 to 2003 it contributes to the existing literature by examining the effect of urbanization taking into account dynamics and the presence of heterogeneity in the sample of countries the results show an inverted u shaped relationship between urbanization and co2 emissions indeed the elasticity emission urbanization is positive for low urbanization levels which is in accordance with the higher environmental impact observed in less developed regions among our contributions is the estimation of a semi parametric mixture model that allows for unknown distributional shapes and endogenously classifies countries into homogeneous groups three groups of countries are identified for which urbanization s impact differs considerably for two of the groups a threshold level is identified beyond which the emission urbanization elasticity is negative and further increases in the urbanization rate do not contribute to higher emissions however for the third group only population and affluence but not urbanization contribute to explain emissions the differential impact of urbanization on co2 emissions should therefore be taken into account in future discussions of climate change policies

returns to scale in convex production technologies the notion of returns to scale rts is well established in data envelopment analysis dea in the variable returns to scale production technology the rts characterization is closely related to other scale characteristics such as the scale elasticity most productive scale size mpss and global rts types indicative of the direction to mpss in recent years a number of alternative production technologies have been developed in the dea literature most of these technologies are polyhedral and hence are closed and convex sets examples include technologies with weakly disposable undesirable outputs models with weight restrictions and production trade offs technologies that include several component production processes and network dea models for most of these technologies the relationship between rts and other scale characteristics has remained unexplored the theoretical results obtained in this paper establish such relationships for a very large class of closed convex technologies of which polyhedral technologies are an important example

cost and learning efficiency drivers in australian schools a two stage network dea approach this article explore performance issues in australian public schools using a two stage dea network model which accounts simultaneously for both cost and learning efficiency levels in the cost efficiency stage different types of expenses and investments are employed to support a given number of students teachers and administrative staff in the learning efficiency stage these groups of individuals help to produce important outputs related to performance in student tests and school rankings results indicate that australian public schools are heterogeneous policy implications are also discussed

the effect of competition on the efficiency of secondary schools in england abstract in this paper we calculate the technical efficiencies based upon multiple outputs school exam performance and attendance rates of all secondary schools in england over the period 1993 1998 we then estimate models to examine the determinants of efficiency in a particular year and the determinants of the change in efficiency over the period our results suggest that the greater the degree of competition between schools the more efficient they are the strength of this effect has also increased over time which is consistent with the evolution of the quasi market in secondary education competition is also found to be an important determinant of the change in efficiency over time there is however some evidence of conditional convergence between schools

income inequality and carbon dioxide emissions the case of chinese urban households abstract this paper draws on chinese survey data to investigate variations in carbon dioxide emissions across households with different income levels rich households generate more emissions per capita than poor households via both their direct energy consumption and their higher expenditure on goods and services that use energy as an intermediate input an econometric analysis confirms a positive relationship between emissions and income and establishes a slightly increasing marginal propensity to emit mpe over the relevant income range the redistribution of income from rich to poor households is therefore shown to reduce aggregate household emissions suggesting that the twin pursuits of reducing inequality and emissions can be achieved in tandem

impact of income inequality and environmental regulation on environmental quality evidence from china abstract china s environmental pollution is of widespread concern and environmental governance has become the country s main method of achieving high quality development environmental quality is a comprehensive indicator which includes many factors such as air water and solid waste pollution this study did not use a single pollutant as a substitute variable for environmental quality firstly we used principal component analysis to construct a comprehensive environmental quality index secondly the stochastic impacts by regression on population affluence and technology and panel quantile regression models were used with data from 30 chinese provinces in china from 1998 to 2017 to analyze the effect of income inequality and environmental regulation on environmental quality the constructed comprehensive index revealed that china s environmental quality had an m type trend over time the mean regression results showed that income inequality and environmental regulation improved environmental quality but higher income inequality reduced environmental quality the panel quantile regression model results revealed that the coefficient of income inequality was positively significant at the 10 30 quantiles and negatively significant at the 70 90 quantiles the coefficients of the absolute value of income inequality at the 10 30 quantiles were less than those at the 70 90 quantiles this implied that higher income inequality reduced environmental quality whereas higher environmental regulations improved environmental quality considering the possible impact of environmental quality on income inequality and environmental regulations we designed a simultaneous equation model to overcome the deviation caused by bilateral causality the conclusions of this study provide policymakers with a new perspective on environmental governance and new paths for achieving high quality development

deregulation and productivity decline the case of spanish savings banks abstract during the 1980s many regulatory constraints limiting competition in spanish banking were relaxed or removed although deregulation came later to savings banks than to the rest of the banking sector two consequences of partial deregulation of savings banks have been a rapid growth in branching activity much of it geographically dispersed and a burst of merger activity in this paper we investigate productive efficiency and total factor productivity change in spanish savings banks over the 1986 1991 post deregulation period neither branching nor mergers provide an adequate explanation for the magnitude or the nature of the productivity decline we observe over the period

income inequality and carbon emissions in the united states a state level analysis 1997 2012 abstract this study investigates the relationship between u s state level co 2 emissions and two measures of income inequality the income share of the top 10 and the gini coefficient each of the inequality measures which focus on unique characteristics of income distributions is used to evaluate the arguments of different analytical approaches results of the longitudinal analysis for the 1997 to 2012 period indicate that state level emissions are positively associated with the income share of the top 10 while the effect of the gini coefficient on emissions is non significant the statistically significant relationship between co 2 emissions and the concentration of income among the top 10 is consistent with analytical approaches that focus on political economy dynamics and veblen effects which highlight the potential political and economic power and emulative influence of the wealthy the null effect of the gini coefficient is generally inconsistent with the marginal propensity to emit approach which posits that when incomes become more equally distributed the poor will increase their consumption of energy and other carbon intensive products as they move into the middle class

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

multi dimensional reference dependent preferences in sealed bid auctions how most laboratory experiments differ from the field abstract we study bidding behavior in first and second price sealed bid auctions with loss averse agents our model predicts overbidding in first price induced value auctions consistent with evidence from most laboratory experiments substantially different bidding behavior could result in commodity auctions where money and auction item are consumed along different dimensions of the consumption space differences also result in second price auctions our study thereby indicates that transferring qualitative behavioral findings from induced value laboratory experiments to the field may be problematic if subjects are loss averse
