how urbanization affects co2 emissions in malaysia the application of stirpat model we investigate the impact of urbanization on co2 emissions by applying the stochastic impacts by regression on population affluence and technology stirpat in the case of malaysia over the period of 1970q1 2011q4 empirically after testing the integrating properties of the variables using the unit root test we applied the bayer hanck combined cointegration approach to examine the cointegration relationship between the variables further we tested the robustness of the long run relationship in the presence of structural breaks using ardl bounds testing approach the causal relationship between the variables is investigated by applying the vecm granger causality test our results validate the existence of cointegration in the presence of structural breaks the empirical results exposed that economic growth is a major contributor to co2 emissions besides energy consumption raises emissions intensity and capital stock boosts energy consumption trade openness leads affluence and hence increases co2 emissions more importantly we find that the relationship between urbanization and co2 emissions is u shaped i e urbanization initially reduces co2 emissions but after a threshold level it increases co2 emissions the causality analysis suggests that the urbanization granger causes co2 emissions

the environment and welfare implications of trade and tax policy developing countries with comparative advantage in dirty industries face the risk of environmental degradation unless appropriate policies are implemented using applied general equilibrium analysis we examine how trade influences the environment and assess the welfare and environmental implications of alternative pollution abatement policies for indonesia our results indicate that unilateral trade liberalization by indonesia would increase the ratio of emission levels to real output for almost all major pollution categories more importantly when tariff removal is combined with a cost effective tax policy the twin objectives of welfare enhancement and environmental quality improvement appear to be feasible this sheds new and positive light on the role of trade in sustainable development

energy consumption carbon emissions and economic growth in saudi arabia an aggregate and disaggregate analysis the objective of this study is to examine the relationship among economic growth carbon emissions and energy consumption at the aggregate and disaggregate levels for the aggregate energy consumption model we use total energy consumption per capita and co2 emissions per capita based on the total energy consumption for the disaggregate analysis we used oil gas and electricity consumption models along with their respective co2 emissions the long term income elasticities of carbon emissions in three of the four models are positive and higher than their estimated short term income elasticities these results suggest that carbon emissions increase with the increase in per capita income which supports the belief that there is a monotonically increasing relationship between per capita carbon emissions and per capita income for the aggregate model and for the oil and electricity consumption models the long and short term income elasticities of carbon emissions are negative for the gas consumption model this result indicates that if the saudi arabian economy switched from oil to gas consumption then an increase in per capita income would reduce carbon emissions the results also suggest that electricity is less polluting than other sources of energy

environmental kuznets curve hypothesis in pakistan cointegration and granger causality abstract the paper is an effort to fill the gap in the energy literature with a comprehensive country study of pakistan we investigate the relationship between co2 emissions energy consumption economic growth and trade openness in pakistan over the period of 1971 2009 bounds test for cointegration and granger causality approach are employed for the empirical analysis the result suggests that there exists a long run relationship among the variables and the environmental kuznets curve ekc hypothesis is supported the significant existence of ekc shows the country s effort to condense co2 emissions and indicates certain achievement of controlling environmental degradation in pakistan furthermore we find a one way causal relationship running from economic growth to co2 emissions energy consumption increases co2 emissions both in the short and long runs trade openness reduces co2 emissions in the long run but it is insignificant in the short run in addition the change of co2 emissions from short run to the long span of time is corrected by about 10 yearly

environmental kuznets curve in romania and the role of energy consumption abstract the aim of present study is to probe the dynamic relationship between economic growth energy consumption and co 2 emissions for period of 1980 2010 in case of romania in doing so ardl bounds testing approach is applied to investigate the long run cointegration between these variables our results confirm long run relationship between economic growth energy consumption and energy pollutants the empirical evidence reveals that environmental kuznets curve ekc is found both in long and short runs in romania further energy consumption is major contributor to energy pollutants democratic regime shows her significant contribution to decline co 2 emissions through effective implementation of economic policies and financial development improves environment i e reduces co 2 emissions by redirecting the resources to environment friendly projects

binary choice models with social network under heterogeneous rational expectations abstract this paper extends brock and durlauf s 2001a 2001b binary choice complete network or group interaction model with homogeneous rational expectations to a general network model with heterogeneous rational expectations in our model individuals will form expectations regarding peers behaviors taking into account their characteristics endogenous contextual and correlated effects are all identifiable conditions for unique equilibrium are established for a complete network with heterogeneous rational expectations multiple equilibria can be characterized by an aggregate scalar index the empirical results on adolescents smoking behaviors show significant endogenous and contextual effects even after controlling for school grade random effects and school fixed effects

social interactions and schooling decisions abstract the aim of this paper is to study whether a child s schooling choices are affected by the schooling choices of other children identification is based on a randomized targeted intervention that grants a cash subsidy conditional on school attendance to a subgroup of eligible children within small rural villages in mexico progresa this policy change spills over to ineligible children if social interactions are relevant results indicate that the eligible children tend to attend school more frequently and the ineligible children acquire more schooling when the subsidy is introduced in their local village moreover the overall effect of progresa on eligible children is the sum of a direct effect due to cash transfers and an indirect effect due to changes in peer group schooling interestingly the social interactions effect is almost as important as the direct effect

the structure of demand for health care latent class versus two part models we contrast the two part model tpm that distinguishes between users and non users of health care with a latent class model lcm that distinguishes between infrequent and frequent users in model comparisons using data on counts of utilization from the rand health insurance experiment rhie we find strong evidence in favor of the lcm we show that individuals in the infrequent and frequent user latent classes may be described as being healthy and ill respectively although sample averages of price elasticities conditional means and event probabilities are not statistically different the estimates of these policy relevant measures are substantively different when calculated for hypothetical individuals with specific characteristics

bayesian analysis of the two part model with endogeneity application to health care expenditure this paper studies the effect of managed care on medical expenditure using a model in which the insurance status is assumed to be endogenous insurance plan choice is modeled through the multinomial probit model the medical expenditure variable the outcome of interest has a significant proportion of zeros that are handled using the two part model extended to handle endogenous insurance the estimation approach is bayesian based on the gibbs sampler the model is applied to a sample of 20 460 individuals obtained from the medical expenditure panel survey the results provide substantial evidence of selectivity copyright 2006 john wiley sons ltd

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

the relationship between energy and production evidence from turkish manufacturing industry this paper investigates the relationship between energy and production at the industry level in an emerging market turkey in a multivariate framework the electricity consumption and value added relation is examined in the turkish manufacturing industry while also accounting for labor and fixed investment we find that labor fixed investment electricity consumption and value added are related via three cointegrating vectors the vec results indicate uni directional causality running from electricity consumption to value added generalized impulse response and variance decomposition analyses confirm these results thus energy input appears to be closely related to production hence energy saving technologies and increased energy efficiency may increase the growth in manufacturing value added

on a clear day you might see an environmental kuznets curve we shed some new light on the environmental kuznets curve ekc and show how it can be viewed as a particular form of equilibrium relationship where technology and preference parameters determine the shape of the curve in contrast to most of the literature on the ekc we estimate a theoretically consistent model on long run data swedish sulfur emission covering the period 1900 2002 furthermore we test and date structural change the model suggests four regimes 1900 1918 1919 1933 1934 1967 and 1968 2002 generating four rather different patterns for pollution over time the policy conclusions are consonant with pearce s general view about the ekc there is no theoretical presumption that it has an inverted u shape nor should any country try to grow out of the environmental problems without analyzing the benefits and costs of so doing

the impact of economic growth on co2 emissions in azerbaijan abstract this paper investigates the relationship between the economic growth and co2 emissions in azerbaijan a cointegration analysis is conducted over the period 1992 2013 for getting more robust results johansen ardlbt dols fmols and ccr methods are employed to explore cointegration and estimate long run coefficients we use cubic quadratic and linear specifications and conclude that the last one is an adequate representation for the impact of the economic growth on co2 emissions in azerbaijan the results from the different cointegration methods are consistent with each other and show that the economic growth has a positive and statistically significant impact on the emissions in the long run implying that the ekc hypothesis does not hold for azerbaijan the income elasticity of co2 emissions using different methods is found to be between 0 7 and 0 8 moreover we find that any short run imbalance can be adjusted towards the long run equilibrium path within less than one year the paper concludes that measures to increase energy efficiency carbon pricing instruments in production and international domestic trade activities and nationwide social awareness programs to instruct about the negative consequences of pollution can be considered as relevant environmental policies aimed at reducing carbon emissions

the relationship between energy demand and real gdp growth rate the role of price asymmetries and spatial externalities within 34 countries across the globe abstract the aim of this paper is to empirically explore the relationship between energy demand and real gross domestic product gdp growth and to investigate the role of regional externalities on per capita final energy consumption fec in 34 countries during the period from 2005 to 2013 the paper utilizes a dynamic panel generalized method of moments dpggm approach and spatial econometric techniques in order to analyse the effect of real gdp growth rate on fec through an error correction model ecm and to examine clustered patterns of energy consumption the results show that a the demand is elastic both in the industrial and the household services sectors b electricity and natural gas are demand substitutes c the relationship between real gdp growth rate and per capita energy consumption exhibits an inverted u shape for all the sample countries under scrutiny 34 countries eurozone and eu28 but not for all the employed sectors of the economy d price electricity and gas and gdp growth asymmetries are supported from the employed parametric tests and e distance does not affect per capita fec but economic neighbours have a strong positive effect

the pollution concern in the era of globalization do the contribution of foreign direct investment and trade openness matter abstract this analysis aims to treat the contribution of the foreign direct investment inflows and trade openness to environmental degradation drawing on the data for 27 african countries over the period from 1990 to 2013 we develop an empirical model based on a set of panel methods this approach includes westerlund 2007 panel cointegration technic common correlated effects mean group cce mg estimation procedure and the granger causality test in terms of long term causality our findings reveal bidirectional long term causality between co2 nox emissions gdp trade openness and foreign direct investment besides in the short run the results recorded a unidirectional causality running from gdp to co2 and from fdi to co2 however bidirectional causality nexus was detected between trade openness and co2 additionally the findings portray bidirectional causality between gdp and nox and between trade openness and nox while a unidirectional causality from foreign direct investment to nox our analysis substantiates the importance of the foreign direct investment inflows and trade openness in mitigating the adverse effect of heavy pollutant activities and resolving the environmental puzzle growing without polluting consistent with the millennium development goals mgds of the un background

does globalization affect growth evidence from a new index of globalization the study develops an index of globalization covering its three main dimensions economic integration social integration and political integration using panel data for 123 countries in 1970 2000 it is analysed empirically whether the overall index of globalization as well as sub indexes constructed to measure the single dimensions affect economic growth as the results show globalization indeed promotes growth the dimensions most robustly related with growth refer to actual economic flows and restrictions in developed countries although less robustly information flows also promote growth whereas political integration has no effect

how economic growth affects emissions an investigation of the environmental kuznets curve in portuguese and spanish economic activity sectors abstract it is a disquieting reality that increased economic growth for many years now in the western world is at odds with environmental degradation in this paper the relationship between economic growth and environmental variables is analyzed under two non linear specifications a quadratic and a cubic specification the study is conducted for portugal and spain in the period 1975 2012 using data for 13 sectors gva is used as proxy for income while energy use and carbon dioxide account for environmental degradation there is evidence for an inverted u shaped ekc however there are also other inverted n shaped functions that explain the relationship between economic growth and emissions altogether empirical results do indicate particular differences between portuguese and spanish sectors the results are of interest not only for researchers but also for policy makers political mitigation measures are also analyzed

the role of trade and fdi for co2 emissions in turkey nonlinear relationships abstract this paper examines the effects of foreign trade and foreign direct investment fdi on co 2 emissions in turkey we consider linear and nonlinear ardl models and find significant asymmetric effects of exports imports and fdi on co 2 emissions per capita however fdi has no statistically significant long run effects in the long run decreases in exports reduce co 2 emissions per capita but increases in exports have no statistically significant effects increases in imports push up co 2 emissions per capita while decreases in imports have no long run effects on the other hand co 2 intensity which measures co 2 emissions per unit of energy is not influenced by exports and imports nor by fdi instead it is affected positively by financial development and urbanization also we find that an environmental kuznets curve is present for both co 2 measures so that increases in real gdp per capita have led to reductions in co 2 emissions for at least the most recent decade controlling for other confounding factors furthermore the sectoral shares of co 2 emissions in total co 2 emissions change asymmetrically with foreign trade for two of four sectors with export increases leading to lower co 2 shares and imports having the opposite effect

free trade and the environment development system abstract we develop a simulation model to analyze the trade environment development system that contains a number of important advances over the earlier and current theoretical models our model like other models has an income induced pollution policy allows country factor endowments to influence trade patterns and allows production factors to be mobile intersectorally unlike other theoretical models our model treats pollution stemming from both production and consumption in a way that does justice to empirical observations we model pollution policy explicitly as an abatement investment thus effectively allowing for differences in pollution intensive technology across countries in addition we allow for an internationally traded intermediate good a natural resource as a result of this novel approach we find that 1 the benefits of trade i can be either positive or negative and ii depend on country endowments and 2 the pollution effects of trade are closely tied to the benefits of trade our model generally shows higher pollution levels under free trade than autarky however our results do not support the pollution haven hypothesis i e trade causes less pollution in developed countries and more pollution in developing ones some developing countries produce more of the pollution intensive good but ultimately consume less pollution under autarky because they have higher per capita income and thus invest more heavily in environmental upgrading under autarky

credibly identifying social effects accounting for network formation and measurement error understanding whether and how connections between agents networks such as declared friendships in classrooms transactions between firms and extended family connections influence their socio economic outcomes has been a growing area of research within economics early methods developed to identify these social effects assumed that networks had formed exogenously and were perfectly observed both of which are unlikely to hold in practice a more recent literature both within economics and in other disciplines develops methods that relax these assumptions this paper reviews that literature it starts by providing a general econometric framework for linear models of social effects and illustrates how network endogeneity and missing data on the network complicate identification of social effects thereafter it discusses methods for overcoming the problems caused by endogenous formation of networks finally it outlines the stark consequences of missing data on measures of the network and regression parameters before describing potential solutions

bayesian spatial probit estimation a primer and an application to hyv rice adoption increasingly spatial econometric methods are becoming part of the standard toolkit of applied researchers in agricultural environmental and development economics nonetheless applications in discrete choice settings remain few and despite its appeal applications of the bayesian paradigm in these settings are still fewer we provide a primer to the bayesian spatial probit with the objective of making accessible to non users a class of iterative estimation methods that have become fairly routine in bayesian circles offer an extremely powerful addition to applied researchers toolkits and are essential in bayesian implementation of spatial econometric models we demonstrate the methods and apply them to estimate the neighbourhood effect in high yielding variety hyv adoption among bangladeshi rice producers we estimate the strength of this relationship using a standard spatial probit model and compare the policy conclusions with and without the neighbourhood effect included

the effect of incentive policies on the practice location of doctors a multinomial probit analysis in this article we estimate a spatial autoregressive multinomial probit model of the choice of location by general practitioners for establishing their initial practice this model allows us to account for potential interdependencies among location choices the model is used to assess the effect of various incentive measures introduced in quebec canada to influence the geographical distribution of physicians across 18 regions our data set covers subperiods before and after the introduction of these measures incentive policies are captured through price and income effects our results provide evidence that these measures had a significant effect on location choices

time varying analysis of co2 emissions energy consumption and economic growth nexus statistical experience in next 11 countries this paper detects the direction of causality among carbon dioxide co2 emissions energy consumption and economic growth in next 11 countries for the period 1972 2013 changes in economic energy and environmental policies as well as regulatory and technological advancement over time cause changes in the relationship among the variables we use a novel approach i e time varying granger causality and find that economic growth is the cause of co2 emissions in bangladesh and egypt economic growth causes energy consumption in the philippines turkey and vietnam but the feedback effect exists between energy consumption and economic growth in south korea in the cases of indonesia and turkey we find the unidirectional time varying granger causality running from economic growth to co2 emissions thus validates the existence of the environmental kuznets curve hypothesis which indicates that economic growth is achievable at the minimal cost of environment the paper gives new insights for policy makers to attain sustainable economic growth while maintaining long run environmental quality

co2 emissions energy consumption and economic growth in turkey abstract this paper examines the long run and causal relationship issues between economic growth carbon emissions energy consumption and employment ratio in turkey by using autoregressive distributed lag bounds testing approach of cointegration empirical results for turkey over the period 1968 2005 suggest an evidence of a long run relationship between the variables at 5 significance level in turkey the estimated income elasticity of carbon emissions per capita is 0 606 and the income elasticity of energy consumption per capita is 1 375 results for the existence and direction of granger causality show that neither carbon emissions per capita nor energy consumption per capita cause real gdp per capita but employment ratio causes real gdp per capita in the short run in addition ekc hypothesis at causal framework by using a linear logarithmic model is not valid in turkish case the overall results indicates that energy conservation policies such as rationing energy consumption and controlling carbon dioxide emissions are likely to have no adverse effect on the real output growth of turkey

how economic growth renewable electricity and natural resources contribute to co2 emissions abstract this study explores the relationship between economic growth and co2 emissions in the so called european union 5 eu 5 countries germany france italy spain and the united kingdom for the 1985 2016 period in doing so we employ a carbon emission function to investigate the environmental kuznets curve phenomenon which describes a relationship between economic growth and environmental degradation the empirical results confirm the existence of an n shaped relationship between economic growth and co2 emissions in the eu 5 countries we incorporate additional variables such as renewable electricity consumption trade openness natural resource abundance and energy innovation to augment the carbon emission function renewable electricity consumption natural resources and energy innovation improve environmental quality while trade openness and the interaction between economic growth and renewable electricity consumption exert a positive impact on co2 emissions this study is novel in that it presents an interaction between economic growth and renewable electricity consumption we also confirm the need for renewable energy regulations related to increasing renewable sources and promoting energy innovation to reduce the negative effects of energy and fossil energy resources on environmental degradation

the socioeconomic determinants of ill gotten gains within person changes in drug use and illegal earnings generalizing from the sociology of earnings attainment we develop a conceptual model of social embeddedness in conventional and criminal activities to explain illegal earnings among criminal offenders to isolate the effects of time varying factors such as legal earnings drug use and criminal opportunities we use data from the national supported work demonstration project to estimate fixed effects models predicting month to month changes in illegal earnings we find that criminal earnings are sensitive to embeddedness in conforming work and family relationships criminal experience and the perceived risks and rewards of crime moreover heroin and cocaine use creates a strong earnings imperative that is difficult to satisfy in the low wage labor market and offenders earn far more money illegally when they are using these drugs than during periods of abstinence

community and capital in entrepreneurship and economic growth we argue that social integration in the sense of within community interconnectedness and venture capital have a complementary relationship in fostering innovation entrepreneurship and economic gr

carbon emissions energy consumption and economic growth an aggregate and disaggregate analysis of the indian economy abstract this study investigates the long and short run relationships among carbon emissions energy consumption and economic growth in india at the aggregated and disaggregated levels during 1971 2014 the autoregressive distributed lag model is employed for the cointegration analyses and the vector error correction model is applied to determine the direction of causality between variables results show that a long run cointegration relationship exists and that the environmental kuznets curve is validated at the aggregated and disaggregated levels furthermore energy total energy gas oil electricity and coal consumption has a positive relationship with carbon emissions and a feedback effect exists between economic growth and carbon emissions thus energy efficient technologies should be used in domestic production to mitigate carbon emissions at the aggregated and disaggregated levels the present study provides policy makers with new directions in drafting comprehensive policies with lasting impacts on the economy energy consumption and environment towards sustainable development

binary choice under social interactions an empirical study with and without subjective data on expectations this paper examines two methods of modeling binary choice with social interactions models assuming homogeneous rational expectations and models using subjective data on expectations exploiting a unique survey conducted during the 1996 us presidential election that was designed to study voting behavior under social context we find that in various model specifications using subjective expectations consistently improves models goodness of fit and that subjective expectations are not rational as formulated by brock and durlauf specifically members characteristics are individually important in forming expectations we also include correlated effect in the rational expectation model this extension provides a remedy to the selection issues that often arise in social interaction models copyright 2008 john wiley sons ltd

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

the multinomial probit model revisited a discussion of parameter estimability identification and specification testing in this paper we examine the multinomial probit model in the light of recent developments in the field of simulation based inference we focus upon five broad areas specification of multinomial choice models parameter estimability and the use of simulation techniques parameter identification specification testing and practical issues in simulation based inference although the substitution of simulated probabilities for difficult to compute multidimensional integrals represents a significant step by examining the more tenuous task of identification and in particular the identification of covariance parameters we show how the specification and estimation of the multinomial probit still represents a formidable task

demand for medical care by the elderly a finite mixture approach summary in this article we develop a finite mixture negative binomial count model that accommodates unobserved heterogeneity in an intuitive and analytically tractable manner this model the standard negative binomial model and its hurdle extension are estimated for six measures of medical care demand by the elderly using a sample from the 1987 national medical expenditure survey the finite mixture model is preferred overall by statistical model selection criteria two points of support adequately describe the distribution of the unobserved heterogeneity suggesting two latent populations the healthy and the ill whose fitted distributions diaer substantially from each other 1997 by john wiley sons ltd

the causality between energy consumption and economic growth in turkey abstract this paper applies the causality test to examine the causal relationship between primary energy consumption ec and real gross national product gnp for turkey during 1970 2006 we employ unit root tests the augmented dickey fuller adf and the philips perron pp johansen cointegration test and pair wise granger causality test to examine relation between ec and gnp our empirical results indicate that the two series are found to be non stationary however first differences of these series lead to stationarity further the results indicate that ec and gnp are cointegrated and there is bidirectional causality running from ec to gnp and vice versa this means that an increase in ec directly affects economic growth and that economic growth also stimulates further ec this bidirectional causality relationship between ec and gnp determined for turkey at 1970 2006 period is in accordance with the ones in literature reported for similar countries consequently we conclude that energy is a limiting factor to economic growth in turkey and hence shocks to energy supply will have a negative impact on economic growth

self employment and the earnings of immigrants we examine the question of the economic returns to immigrants engaged in self employment based on samples of four entrepreneurial immigrants plus control samples of blacks and whites from the 1980 u s public use microdata sample we find large differences in the net effect of self employment depending on the use of a linear absolute dollar values or loglinear relative returns form we examine various explanations for the discrepancy and identify the role of outliers as significant the loglinear form fits the data better but at the cost of obliterating substantively important information namely the preponderance of the self employed among positive outliers effects of excluding the latter from the linear form and the theoretical and policy implications of alternative specifications of the earnings equation are examined excerpt

what drives carbon dioxide emissions in the long run evidence from selected south asian countries abstract this study empirically investigates the relationship between co 2 emission and four of its potentially contributing factors i e energy consumption income trade openness and population using time series data from 1971 to 2013 on five selected economies of south asia after confirming that all the series are stationary using unit root test process the study incorporates three different and advance panel cointegration tests i e pedroni kao and johansen fisher panel cointegration all the panel cointegration tests confirm that all the variables cointegrated the long run association between the variables is checked using fmols grouped and individual cross section country in the panel the fmols grouped results show that energy consumption trade openness and population increases environmental degradation in the panel countries with exception of income which has negative impact and sounds the existence of environmental kuznet curve between income and emission the innovative accounting approach using variance decomposition test and impulse response function is applied to examine the causality amongst the underlined vectors the results show that there is bidirectional causality between energy consumption and trade openness and uni directional causality running from energy consumption trade openness and population to co 2 emission the results enumerate that the energy consumption and population density will increase in long run and foresee further environmental degradation in the region

impact of corruption in public sector on environmental quality implications for sustainability in brics and next 11 countries abstract this study investigates the impact of corruption in public sector on carbon emissions in presence of energy use segregation following the environmental kuznets curve ekc framework the study has been carried out for brazil russia india china south africa brics and next 11 countries over the period of 1990 2017 along with the finding of inverted n shaped ekc for both the cases we find that incidents of corruption enhance environmental degradation by reducing the positive impact of renewable energy consumption on environmental quality and increasing the negative impact of fossil fuel consumption this study has also divulged that the corruptive practices are more prone in case of the countries where the development is mature and institutionalization is more stringent based on these findings we suggest that environmental policies should take account of the corruption and thereby making the policies more robust and effective

semi parametric estimation of hurdle regression models with an application to medicaid utilization this paper develops a semi parametric estimation method for hurdle two part count regression models the approach in each stage is based on laguerre series expansion for the unknown density of the unobserved heterogeneity the semi parametric hurdle model nests poisson and negative binomial hurdle models which have been used in recent applied literature the empirical part of the paper evaluates the impact of managed care programmes for medicaid eligibles on utilization of health care services using a key utilization variable the number of doctor and health centre visits health status measures and age seem to be more important in determining health care utilization than other socio economic and enrollment variables the semi parametric approach is particularly useful for the analysis of overdispersed individual level data characterized by a large proportion of non users and highly skewed distribution of counts for users 1997 john wiley sons ltd

decomposition of co2 emissions over 1980 2003 in turkey abstract there is a multi dimensional need for studying the energy situation in turkey and to obtain insight into the development of co2 emissions on the one hand recent projections of the oecd show that turkey has a yearly gdp growth potential of over 7 on the other hand recent projections of undp and world bank indicate that the level of co2 emission is going to rise six fold by 2025 with respect to the level of emissions in 1990 it is a great challenge to both meet the growth target and keep the co2 under control thereupon this paper tries to unfold factors that explain co2 emissions by undertaking a complete decomposition analysis for turkey over the period 1980 2003 the analysis shows as is common to relatively fast growing economies that the biggest contributor to the rise in co2 emissions is the expansion of the economy scale effect the carbon intensity and the change in composition of the economy which nearly move in tandem also contribute to the rise in co2 emissions albeit at a slower rate the energy intensity of the economy which is decreasing is responsible for a modest reduction in co2 emissions hence in congruence with the scale effect a decoupling of carbon emissions and economic growth is not found in turkey over the period 1980 2003

literature survey on the relationships between energy environment and economic growth abstract the aim of this study is to exhibit an exhaustive survey which is related to the great flight of the literature of energy environment growth nexus at the individual and regional scale studies covering the period from 1978 to 2014 the survey takes into consideration the sample country region etc periods covering econometric strategies and conclusions our survey is based on the causality direction among i the energy use variables electricity nuclear renewable and non renewable and output growth ii between economic growth and environment and between the three variables at the same time globally these surveys provide paradoxical and not conclusive results which energy consumption can boost economic growth through the productivity enhancement and it can boost also the environmental damages through the enhancement of pollutant emissions our survey sheds more the lights on the energy environment growth literature by giving an extensive listing 1978 2014 of these causal linkages among the energy use variables environment and economic growth for both individual and collective cases there is a unanimous consensus about the importance of dealing with such dynamic relationship which is seems to be a cornerstone element in setting any ambition strategies energy ecological and economics

validating the environmental kuznets curve hypothesis in india and china the role of hydroelectricity consumption abstract the aim of this research is to examine the link between co 2 emissions hydroelectricity consumption urbanisation and real gdp in china and india during the period of 1965 2013 the long run cointegration is investigated by the autoregressive distributed lag ardl bounds testing approach which is augmented with structural breaks we employ the ardl cointegration test to establish long run relationship in the variables furthermore we use the ardl to show that real gdp and urbanisation have long run positive impact on emission while hydroelectricity consumption exerts long run negative impact on emission in both countries the results support the existence of environmental kuznets curve ekc hypothesis in china and india besides the paper assesses the causal link between the variables by using granger causality procedures and the results show that there is long run bidirectional relationship between the variables in both countries

spatial price competition a semiparametric approach we investigate the nature of price competition among firms that produce differentiated products and compete in markets that are limited in extent we propose an instrumental variables series estimator for the matrix of cross price response coefficients demonstrate that our estimator is consistent and derive its asymptotic distribution our semiparametric approach allows us to discriminate among models of global competition in which all products compete with all others and local competition in which products compete only with their neighbors we apply our semiparametric estimator to data from u s wholesale gasoline markets and find that in this market competition is highly localized

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

exploring the relationship between energy usage segregation and environmental degradation in n 11 countries numerous studies regarding the economic growth environmental pollution link have struggled to determine the effects of various forms of energy consumption on environmental degradation particularly in the context of emerging economies this study examines the environmental kuznets curve ekc for co2 emissions in n 11 countries during 1990 2014 by segregating three forms of energy consumption renewable biomass and non renewable urbanization and trade openness are additional explanatory variables that are used in the empirical framework using the generalized moments method gmm the empirical evidence confirms the presence of an n shaped relationship between economic growth and environmental degradation for n 11 countries this study analyzed the interaction effects among trade openness biomass consumption and economic growth these interactions had a negative impact on co2 emissions levels of n 11 countries suitable policy recommendations have been provided based on the detailed results

sectoral energy consumption by source and economic growth in turkey this paper provides a detailed analysis of the energy consumption in turkey during the last 40 years it investigates the causal relationships between income and energy consumption in two ways first the relationship is studied at the aggregate level then we focus on the industrial sector previous findings suggest that in the case of turkey there is a unidirectional causality running from energy consumption to growth however our findings suggest that in the long run income and energy consumption appear to be neutral with respect to each other both at the aggregate and at the industrial level we also find a strong evidence of instantaneous causality which means that contemporaneous values of energy consumption and income are correlated furthermore a descriptive analysis is conducted in order to reveal the differences in the use of energy resources we conclude that energy conservation policies are necessary for environmental concerns and our empirical results imply that such policies would not impede economic growth in the long term

why cooperate public goods economic power and the montreal protocol this paper develops a correlated probit model to describe dichotomous choices that may contain a public goods component or some other forms of interdependency the key contribution of the paper is to formulate tests for interdependent behavior among agents in particular we examine the decisions by nations whether or not to ratify the montreal protocol on substances that deplete the ozone layer specifically we reject free riding as a motive for not ratifying the protocol and we find little evidence that individual nations were influenced by the behavior of their largest trading partners hence the data suggest that with respect to the montreal protocol most nations acted without regard for the actions of other nations

trade politics and the environment tailpipe vs smokestack abstract the vast majority of economic research on environmental regulation in open economies focuses on producer generated smokestack pollution we instead consider consumer generated tailpipe pollution we examine how political opposition to environmental regulation varies with a country s trade regime and show that the impact on environmental policy of a move from autarky to free trade can depend critically on who ultimately generates pollution producers or consumers we find that opening to trade may raise industry opposition to smokestack regulation but reduce its opposition to strict tailpipe policy

immigrant self employment the family as social capital and the value of human capital we examine how self employment among asian and hispanic immigrants is affected by family composition and human capital class resources because of collective interests and strong personal ties the family facilitates the pooling of labor power and financial resources enterprising immigrants draw on these resources when establishing and operating small businesses our findings also show the importance of human capital class resources in accounting for immigrant self employment although foreign earned human capital is usually not highly valued in the host labor market immigrants successfully use this human capital to achieve business ownership interethnic variation in personal human capital and family composition accounts for a substantial portion of the observed interethnic variation in self employment the data are drawn from the 1980 five percent pums for greater new york city and los angeles excerpt

structural break unit root and the causality between energy consumption and gdp in turkey abstract this paper tries to investigate a series of unit root and causality tests to detect causality between the gdp and energy consumption in turkey employing hsiao s version of granger causality method for the 1950 2000 period the conventional unit root tests indicate the series are i 1 whereas the endogenous break unit root tests proposed by zivot and andrews zivot e and andrews d w k 1992 further evidence on the great crash the oil price shock and the unit root hypothesis journal of business and economics statistics 10 251 270 and perron perron p 1997 further evidence on breaking trend functions in macroeconomic variables journal of econometrics 80 355 385 reveal that the series are trend stationary with a structural break therefore it is inappropriate to take the first difference of the data to achieve stationarity the main conclusion of this study is that there is no evidence of causality between energy consumption and gdp in turkey based on the detrended data

does trade liberalization harm the environment a new test recent events such as the nafta and the completion of the uruguay round have raised concern over the impact of trade liberalization on the environment in particular it is believed that less stringent environmental standards in developing countries will give them a comparative advantage in pollutionintensive goods using single equation models existing empirical studies have found either no relationship between environment and trade flows or a positive relationship between trade liberalization and the environment this paper develops a simultaneous equations model to estimate this relationship directly incorporating the effects of openness on growth of income and of income growth on environmental damage a two good trade model with endogenous factor supply is estimated using pooled provincial data on chinese water pollution from 1987 1995 estimation of this model reveals that trade liberalization directly aggravates environmental damage via its influence on the terms of trade but indirectly mitigates it via its effect on income growth simulations suggest that trade reform during the period may have had a net beneficial impact on emissions growth

the choice of medical providers in rural benin a comparison of discrete choice models in this paper we estimate three different discrete choice models of provider choice using data from the rural district of ouidah in benin these three model are multinomial logit ml 2 independent multinomial probit imp 3 multinomial probit mp a comparison of imp and mp allows us to reject the independence assumption between providers furthermore the cross price elasticities computed from the restrictive specifications ml and imp are dramatically different from those computed from the more general one mp these results cast some doubt on the validity of the previous findings and policy recommendations that are typically based on the ml specification

the link between green taxation and economic growth on co2 emissions fresh evidence from malaysia abstract this paper explores how carbon taxation and economic growth affect environment hazards in malaysia using time series data over the period 1974 2010 we applied cointegration and causality approaches to determine the long term cointegration and direction of causal relationship between these variables based on the results we found the cointegration relationship between the variables furthermore we noted that although kuznets theory i e inverted u shaped curve between economic growth and co 2 emissions is valid for malaysia the carbon taxation policy is ineffective to control co 2 emissions the causality analysis revealed that there is a bidirectional relationship between carbon tax and co 2 emissions economic growth granger causes co 2 emissions and carbon tax granger causes economic growth to enhance the awareness concerning pollution issues governments should rely on alternative instruments that may give benefit to the taxpayers and reduce pollution which is the pivotal issue to be tackled globally

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

revisiting the environmental kuznets curve in a global economy the present study deals with an empirical investigation between co2 emissions energy intensity economic growth and globalization using annual data over the period of 1970 2010 for turkish economy we applied unit root test and cointegration approach in the presence of structural breaks the direction of causality between the variables is investigated by applying the vecm granger causality approach our results confirmed the existence of cointegration between the series the empirical evidence reported that energy intensity and economic growth globalization increase condense co2 emissions the results also validated the presence of environmental kuznets curve ekc the causality analysis shows bidirectional causality between economic growth and co2 emissions this implies that economic growth can be boosted at the cost of environment

heterogeneity in ordered choice models a review with applications to self assessed health discrete variables that have an inherent sense of ordering across outcomes are commonly found in large data sets available to many economists and are often the focus of research however assumptions underlying the standard ordered probit which is usually used to analyse such variables are not always justified by the data this study provides a review of the ways in which the ordered probit might be extended to account for additional heterogeneity differing from other reviews in scope application and relevance in economic settings a series of issues pertaining to choices of variables and the economic assumptions underlying each model are discussed in the context of measuring the underlying health of respondents the models are applied to a wave of the household income and labour dynamics in australia survey in order to check the appropriateness of such assumptions in an applied context

energy consumption economic growth and carbon emissions challenges faced by an eu candidate member abstract this paper investigates the long run granger causality relationship between economic growth carbon dioxide emissions and energy consumption in turkey controlling for gross fixed capital formation and labor the most interesting result is that carbon emissions seem to granger cause energy consumption but the reverse is not true the lack of a long run causal link between income and emissions may be implying that to reduce carbon emissions turkey does not have to forgo economic growth

the impact of foreign direct investment on environmental quality a bounds testing and causality analysis for turkey abstract this study aims to investigate the impact of foreign direct investment fdi together with gross domestic product gdp the square of gdp and energy consumption on carbon dioxide co2 emissions in turkey over the period 1974 2010 we employ both the bounds test approach which has superior properties especially in small samples and the hatemi j test which takes structural breaks into consideration in the co integration analysis due to the co integration relationship between co2 emissions and other variables the autoregressive distributed lag ardl model is used in order to investigate short and long run elasticity between the variables the long run coefficients of the ardl model indicate that the effect of fdi on co2 emissions is positive but relatively small while the effects of the gdp and energy consumption on co2 emissions are quite considerable moreover the short run coefficients obtained by the error correction model ecm are found to be similar to those of the long run model the findings support the validity of the environmental kuznets curve ekc hypothesis in both time horizons the vector ecm based granger causality test is also applied to investigate the causal link the causality test results indicate the existence of a causality running from all explanatory variables to co2 emissions in the long run overall the findings suggest that turkey should promote energy efficiency with sustainable growth and encourage more fdi inflows particularly in technology intensive and environment friendly industries to improve environmental quality

ethnic enclaves and the earnings of self employed latinos in the investigation reported here i have tested the ethnic enclave hypothesis focusing on self employed cuban and mexican immigrants specifically i have compared the economic returns for self employed cuban immigrants in florida with those of mexican immigrants in california and texas the analysis shows that self employed mexican immigrants who remain within mexican enclaves earn substantially lower earnings than those in non enclave environments in contrast the earnings of cuban immigrants self employed within cuban enclaves are comparable to those earned by cubans employed within the general labor market overall my findings are contrary to the ethnic enclave hypothesis which suggests that there are economic advantages associated with owning firms in ethnic enclaves

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
