foreign direct investment in turkey regional determinants the uneven regional distribution of foreign direct investment fdi in turkey poses an interesting question from the perspective of multinational firms mnfs and policy makers alike this paper focuses on the factors governing the location decisions of mnfs within turkey with specific reference to policy implications using a conditional logit model it is found that agglomeration depth of local financial markets human capital and coastal access dominate location decisions for the aggregate sample of foreign investors in turkey this study reveals no evidence that public investment is successful in attracting mnfs to particular regions also importantly the location determinants vary dramatically by broad industrial category investment composition and origin country characteristics including income category and region

does foreign direct investment impede environmental quality in high middle and low income countries abstract under a multivariate framework this paper aims to investigate the nonlinear correlation between foreign direct investment and environmental degradation for high middle and low income countries with economic growth and energy consumption as additional determinants of environmental degradation all variables were found to be nonstationary and cointegrated based on recent panel data unit root tests and cointegration techniques on applying fully modified ordinary least squares fmols the long run results suggest the presence of an environmental kuznets curve in turn foreign direct investment increases environmental degradation thus confirming the pollution haven hypothesis phh moreover the bidirectional causality between co2 emissions and foreign direct investment is observed globally the findings are sensitive to different income groups and regional analyses in particular these empirical findings aid sound economic policymaking for improving environmental quality and sustainable economic development

long run effects of public sector sponsored training in west germany between 1991 and 1997 west germany spent on average about 3 6 bn euro per year on public sector sponsored training programmes for the unemployed we base our empirical analysis on a new administrative data base that plausibly allows for selectivity correction by microeconometric matching methods we identify the effects of different types of training programmes over a horizon of more than seven years using bias corrected weighted multiple neighbours matching we find that all programmes have negative effects in the short run and positive effects over a horizon of about four years however for substantive training programmes with duration of about two years gains in employment probabilities of more than 10 points appear to be sustainable but come at the price of large negative lock in effects

foreign investment and spillover efficiency in an underdeveloped economy evidence from the mexican manufacturing industry abstract in this paper we consider the question whether differences in technical efficiency of mexican plants in part derive from spillover efficiency associated with foreign direct investment we use labour productivity as a measure of technical efficiency and relate this to capital intensity labour quality and scale of production we measure the degree of competition by different concentration indices and the final factor determining efficiency is the presence of foreign subsidiaries if there is a positive relation between efficiency of domestic plants and the foreign participation of various industries we conclude that there is a spillover of technical efficiency the empirical evidence from the study indicates that this is the case

optimal welfare to work programs a welfare to work wtw program is a mix of government expenditures on various labour market policies targeted to the unemployed e g unemployment insurance m job search monitoring m social assistance sa wage subsidies this paper provides a dynamic principal agent framework suitable for analysing chief features of an optimal wtw program such as the sequence and duration of the different policies the dynamic pattern of payments along the unemployment spell and the emergence of taxes subsidies upon re employment the optimal program endogenously generates an absorbing policy of last resort social assistance characterized by a constant lifetime payment and no active participation by the agent human capital depreciation is a necessary condition for policy transitions to be part of an optimal wtw program the typical sequence of policies is quite simple the program starts with standard ui then switches into monitored search and finally into sa the optimal benefits are decreasing during unemployment insurance and constant during both jm and sa whereas taxes subsidies can be either increasing or decreasing with duration during ui they must decrease increase during a phase of jm in a calibration exercise we use our model to analyse quantitatively the features of the optimal program for the u s economy with respect to the existing u s system the optimal wtw scheme delivers sizeable welfare gains to unskilled workers because the incentives to search for a job can be retained even while delivering more insurance and using costly monitoring less intensively

job search and unemployment insurance new evidence from time use data article i nfo this paper provides new evidence on job search intensity of the unemployed in the u s modeling job search intensity as time allocated to job search activities the major findings are 1 the average u s unemployed worker devotes about 41 min to job search on weekdays which is substantially more than their european counterparts 2 workers who expect to be recalled by their previous employer search substantially less than the average unemployed worker 3 across the 50 states and d c job search is inversely related to the generosity of unemployment benefits with an elasticity between 1 6 and 2 2 4 job search intensity for those eligible for unemployment insurance ui increases prior to benefit exhaustion and 5 time devoted to job search is fairly constant regardless of unemployment duration for those who are ineligible for ui

does foreign direct investment lead to lower co2 emissions evidence from a regional analysis in china abstract existing studies have been concerned with the relationship between foreign direct investment and co2 emissions in recent years however little attention has been paid to regional differences in china this paper investigates the impact of fdi on china s co2 emissions at the national and regional levels using provincial panel data from 1995 to 2010 the stochastic impacts by regression on population affluence and technology stirpat model was adopted the results suggest that fdi contributes to co2 emission reductions in china fdi s impact on co2 emissions decreases from the western region to the eastern and central regions our findings support the pollution halo hypothesis which claims that foreign firms can export greener technologies from developed to developing countries and conduct business in an environmentally friendly manner

the relevance of p star analysis to uk monetary policy recent articles have attempted to restore the use of a simple measure of the money supply as an indicator of future price levels p star and to reestablish a causal link from money to prices in this paper we argue that the p star approach is flawed it is certainly more complex than traditional monetarist approaches but the fundamental questions of causality are in no way either affected or resolved we argue that the p star relationship does not have a causal link with prices but rather the causality runs from prices to money we also find that there is some causality running from money to real income so that monetary conditions do seem to have some predictive power for future levels of activity copyright 1994 by royal economic society

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

pollution energy use gdp and trade estimating the long run relationship for vietnam abstractsince the beginning of economic reform in the 1980s and in particular with its openness to international trade accelerating since the 1990s the vietnamese economy has registered significant growth at the same time energy consumption and the level of pollution in vietnam has also increased this article aims to focus on the link between openness to trade and pollution in vietnam due to lack of data very few existing studies have focused on vietnam using annual data from1980 to 2011 and employing the bounds testing approach to cointegration based on an autoregressive distributed lagged ardl model we find that there is a statistically significant long run relationship amongst pollution openness to trade energy consumption and real national income in vietnam this conclusion continues to hold when the possibility of a structural break in the relationship is allowed for using the gregory hansen approach to cointegration analysis of the cointegration relationship suggests that in respons

a var approach to the economics of fdi in china using a vector autoregression var approach this study re examines several hypotheses suggested by the economic literature on the economics of fdi applying quarterly time series data from china a country which has recently become the second largest host country for fdi innovation accounting variance decomposition and impulse response function analysis is applied to analyse the various interrelationships between fdi and other economic variables of interest in a var system the empirical research using this method in the case of china is limited the study therefore provides an interesting advance in the literature on the economics of fdi in china

investigation of the environmental kuznets curve for carbon emissions in malaysia do foreign direct investment and trade matter abstract environmental degradation has become a central issue of discussion among the economists and environmentalists in view of malaysia s position as one of the main contributors to co2 emissions in asia and its status as a fast growing economy it is vital therefore to conduct a study to identify the relationship between economic growth and co2 emissions for malaysia this study attempts to examine empirically the environmental kuznets curve hypothesis for malaysia in the presence of foreign direct investment and trade openness both in the short and long run for the period 1970 to 2008 the bounds testing approach and granger causality methodology are applied to test the interrelationships of the variables the results of our study indicate that the inverted u shaped relationship does exist between economic growth and co2 emission in both the short and long run for malaysia after controlling for two additional explanatory variables namely fdi and trade importantly the results of the study also provide some crucial policy recommendations to the policy makers

female headed households poverty and the welfare of children in urban brazil this study describes female headed households and analyzes the determinants of poverty among these households and the consequences for children data are obtained from the brazilian pesquisa national por amostra de domicilios pnad for mostly 1984 and some other years historically brazil has always had a large proportion of female headed households in part due to the plantation culture and the need for male labor migration to plantations this study focuses on households in recife sao paulo and porto alegre these metro areas reflect a variety of socioeconomic conditions two alternative definitions of headship are compared and caution is urged in using too narrow a concept of headship in situations such as in this study where households depend upon more than one income earner income levels varied across the three regions mean income in sao paulo and porto alegre was similar income in recife was much lower there were more female headed households per capita in recife the general trend was that the lower the relative income the higher the likelihood of being a female headed household female headed households with minors and moynihan type households had the greatest proportion in the lower income groups it is concluded that 1 female headships were heterogenous 2 the extent of poverty of female headed households varied by region and was the greatest in the northeast and 3 female headed households were poorer because females earned less than males lower female income was related to lower hours worked and the tendency of women to work in occupations that paid lower salaries or to hold low status occupations employers were faulted for failing to hire women for higher paying jobs or to pay salaries on par with male counterparts single mother headed households in urban areas were 3 4 of households but these households with children tended to be poor and were designated a vulnerable group not all female headed households were vulnerable particularly those in the south interventions should be targeted at children who are most at risk for poor school attendance at ages 10 14 years in poor female headed households children were worse off in recife where there was a stronger association between poverty and female headship only children in female headed households had decreased school attendance with increasing age the analysis of the poverty effect on children indicated different impacts in each metro area

relationships between economic growth foreign direct investment and trade evidence from china this study investigates the causal links between trade economic growth and inward foreign direct investment fdi in china at the aggregate level the integration and cointegration properties of quarterly data are analysed long run relationships between growth exports imports and fdi are identified in a cointegration framework in which this paper finds bi directional causality between economic growth fdi and exports economic development exports and fdi appear to be mutually reinforcing under the open door policy

does human capital constrain the impact of foreign direct investment and remittances on economic growth in ghana this article empirically investigates whether human capital constrains the impact of foreign direct investment fdi and remittances on economic growth in ghana an economic growth model for ghana is specified and estimated using fully modified ordinary least squares fmols estimator and employing annual data spanning the period 1965 to 2008 empirical results indicate that fdi and remittances are key determinants of economic growth in ghana results indicate that human capital enhances the impact of fdi and remittances on economic growth although both government expenditure and trade openness are growth enhancing government expenditure appears to crowd out private investment empirical results also indicate that domestic inflationary pressures unstable political environment and volatile global economy exert a negative impact on economic growth in ghana

causality between income and emission a country group specific econometric analysis abstract empirical studies of the environmental kuznets curve ekc examine the presence or otherwise of an inverted u shaped relationship between the level of pollution and the level of income customarily in the diagram of ekc the level of income is shown on the horizontal axis and that of pollution on the vertical axis thus it is presumed that the relationship between income and pollution is one of unidirectional causality with income causing environmental changes and not vice versa the validity of this presumption is now being questioned it is being asserted that the nature and direction of causality may vary from one country to the other in this paper we present the results of a study of income co 2 emission causality based on a granger causality test to cross country panel data on per capita income and the corresponding per capita co 2 emission data briefly our results indicate three different types of causality relationship holding for different country groups for the developed country groups of north america and western europe and also for eastern europe the causality is found to run from emission to income for the country groups of central and south america oceania and japan causality from income to emission is obtained finally for the country groups of asia and africa the causality is found to be bi directional the regression equations estimated as part of the granger causality test further suggest that for the country groups of north america and western europe the growth rate of emission has become stationary around a zero mean and a shock in the growth rate of emission tends to generate a corresponding shock in the growth rate of income in contrast for the country groups of central and south america oceania and japan a shock in the income growth rate is likely to result in a corresponding shock in the growth rate of emission finally causality being bi directional for the country groups of asia and africa the income and the emission growth rates seemed to reinforce each other

optimal unemployment insurance with human capital depreciation and duration dependence this paper studies the effect of human capital depreciation and duration dependence on the design of an optimal unemployment insurance ui scheme our results partially confirm those obtained in most previous studies benefits should decrease with unemployment duration the optimal program also generates two main novel features which are not present in stationary models first if human capital depreciates rapidly enough during unemployment ui transfers are bounded below by a minimal assistance level that arises endogenously in the efficient program second we study the optimality of imposing a history contingent wage tax after reemployment our numerical simulations based on the spanish and us economies show that the wage tax should decrease with the length of worker s previous unemployment spell and become a wage subsidy for long term unemployed workers as a by product of our study we develop a systematic approach suitable for studying recursively a wide range of dynamic moral hazard problems and other models with similar characteristics

moral hazard vs liquidity and optimal unemployment insurance this paper presents new evidence on why unemployment insurance ui benefits affect search behavior and develops a simple method of calculating the welfare gains from ui using this evidence i show that 60 percent of the increase in unemployment durations caused by ui benefits is due to a liquidity effect rather than distortions on marginal incentives to search moral hazard by combining two empirical strategies first i find that increases in benefits have much larger effects on durations for liquidity constrained households second lump sum severance payments increase durations substantially among constrained households i derive a formula for the optimal benefit level that depends only on the reduced form liquidity and moral hazard elasticities the formula implies that the optimal ui benefit level exceeds 50 percent of the wage the exact identification approach to welfare analysis proposed here yields robust optimal policy results because it does not require structural estimation of primitives

foreign direct investment pollution and economic growth evidence from malaysia the bounds test developed by pesaran et al 2001 is applied to examine the existence of a long run relationship between foreign direct investment fdi inflows pollution and output of malaysia granger causality tests are also utilized to test for the presence of the short run and long run causal relationship between these variables both fdi inflows and pollution have short run causal relationship on output output only has long run causal relationship on fdi inflows

foreign direct investment and growth in india a cointegration approach the two way link between foreign direct investment and growth for india is explored using a structural cointegration model with vector error correction mechanism the existence of two cointegrating vectors between gdp fdi the unit labour cost and the share of import duty in tax revenue is found which captures the long run relationship between fdi and gdp a parsimonious vector error correction model vecm is then estimated to find the short run dynamics of fdi and growth our vecm model reveals three important features a gdp in india is not granger caused by fdi the causality runs more from gdp to fdi b trade liberalization policy of the indian government had some positive short run impact on the fdi flow and c fdi tends to lower the unit labour cost suggesting that fdi in india is labour displacing

investigating the validity of pollution haven hypothesis in the gulf cooperation council gcc countries this study investigated the validity of the pollution haven hypothesis in the gulf cooperation council gcc countries using a multivariate framework to achieve the goal of this study the non stationary panel techniques were used to examine the hypothesis from 1980 to 2009 based on the pedroni cointegration test results it was found that the variables are cointegrated moreover the fully modified ols results showed that energy consumption and gdp growth increase co2 emission while foreign direct investment inflows have a long run negative relationship with co2 emission furthermore based on the short run granger causality test results fdi has no short run causal relationship with co2 emission and energy consumption while energy consumption and gdp growth have a positive causal relationship with co2 emission thus the results of this study indicate that energy consumption and gdp growth are the source of pollution in the gcc countries and not the foreign direct investment inflows thus the study recommended that these countries should utilize policies to encourage inward foreign investment since it plays an important role in stimulating gdp growth

training and search during unemployment displaced workers often experience large losses in earnings even a long time after reemployment training programs during unemployment mitigate these losses but also affect the unemployed s willingness to search this paper analyzes how mandatory training programs affect the optimal design of unemployment insurance and how the training intensity should evolve during the unemployment spell the introduction of training reverses the optimal consumption dynamics during the unemployment spell and makes it optimal to incentivize the long term unemployed to find employment despite the depreciation of their human capital targeting training programs towards the long term unemployed however is optimal only if the fall in human capital upon displacement is small relative to the depreciation during unemployment

public policy in a model of long term unemployment this paper considers a model in which the unemployed have to incur a cost to maintain their skills if whether they have done so is not observable the economy has multiple equilibria supported by self fulfilling beliefs on the part of the employers one of these equilibria which we argue is more likely to arise has equilibrium discrimination against the long term unemployed who in response decide to let their skills atrophy as a result in this equilibrium the exit probabilities from unemployment are duration dependent it is shown that equilibrium discrimination survives even if workers are allowed to accept negative wages at the beginning of the employment relation since this equilibrium is highly inefficient constructive government action in the form of positive discrimination subsidies and labour market policies are suggested to correct the market failures however subsidies and positive discrimination by private firms are shown not to have beneficial effects labour market policies in the form of retraining of the long term unemployed are beneficial but reduce the likelihood of a switch to the pareto preferred equilibrium the most useful policy appears to be a limited form of positive discrimination by a government sector

wage risk and employment risk over the life cycle we specify a structural life cycle model of consumption labour supply and job mobility in an economy with search frictions that allows us to distinguish between different sources of risk and to estimate their effects the sources of risk are shocks to productivity job destruction the process of job arrival when employed and unemployed and match level heterogeneity our model allows for four main social insurance programmes in contrast to simpler models that attribute all income fluctuations to shocks our framework allows us to disentangle the effects of the shocks from the responses to these shocks estimates of productivity risk once we control for employment risk and for individual labour supply choices are substantially lower than estimates that attribute all wage variation to productivity risk increases in productivity risk impose a considerable welfare loss on individuals and induce substantial precautionary saving increases in employment risk have large effects on output and primarily through this channel affect welfare the welfare value of government programs such as food stamps which partially insure productivity risk is greater than the value of unemployment insurance which provides partial insurance against employment risk and no insurance against persistent shocks

liquidity and insurance for the unemployed we study the optimal design of unemployment insurance for workers sampling job opportunities over time we focus on the optimal timing of benefits and the desirability of allowing workers to freely access a riskless asset when workers have constant absolute risk aversion preferences it is optimal to use a very simple policy a constant benefit during unemployment a constant tax during employment that does not depend on the duration of the spell and free access to savings using a riskless asset away from this benchmark for constant relative risk aversion preferences the welfare gains of more elaborate policies are minuscule our results highlight two largely distinct roles for policy toward the unemployed a ensuring workers have sufficient liquidity to smooth their consumption and b providing unemployment benefits that serve as insurance against the uncertain duration of unemployment spells

optimal unemployment insurance this paper considers the design of an optimal unemployment insurance system the problem is modeled as a repeated principalagent problem involving a risk averse agent the unemployed worker and a risk neutral principal which cannot monitor the agent s search effort the optimal long term contract subject to the associated incentive constraints is characterized this contract involves a replacement ratio that decreases throughout the unemployment spell and a wage tax after reemployment that under some mild regularity conditions increases with the lenght of the unemployment spell some numerical results are presented that suggest that the gains from switching to this optimal unemployment insurance scheme could be quite large the performance of this optimal contract is also compared to alternative liquidity provision mechanisms

optimal unemployment insurance and employment history in existing unemployment insurance programmes it is standard to condition eligibility on the previous employment record of unemployed workers the purpose of this article is to study conditions under which the efficient contract exhibits these properties in order to do so we characterize the optimal unemployment insurance contract in asymmetric information environments in which workers experience multiple unemployment spells we show that if quits cannot be distinguished from layoffs it is optimal to condition the benefits paid to unemployed workers on their employment history in particular the coverage should increase with the length of previous employment spells copyright wiley blackwell

electricity use and economic development abstract a study of the relationship between electricity use and economic development in over one hundred countries constituting over 99 of the global economy has been undertaken correlations between electricity consumption capita and gdp capita have been analysed and compared with those between total primary energy supply capita and gdp capita a supporting analysis has correlated the proportion of energy used in the form electricity the e e ratio with gdp capita the general conclusions of this research are that wealthy countries have a stronger correlation between electricity use and wealth creation than do poor countries and that for the global economy as a whole there is a stronger correlation between electricity use and wealth creation than there is between total energy use and wealth the study also shows that in wealthy countries the increase in wealth over time correlates with an increase in the e e ratio the results imply that the energy ratio toe should be replaced by the electricity ratio kwh as a development indicator and more precisely by the e e ratio kwh toe

attendance and pricing at sporting events empirical results from granger causality tests for the melbourne cup this study applies granger causality tests to examine the relationship between attendance admission prices and real income at the melbourne cup which is australia s premier horseracing event and one of the world s leading handicap races the motivation for the paper is that while market demand suggests that causation should run from admission price to attendance it is equally plausible that sporting authorities could alter admission prices in response to a change in demand reflected in attendance the main findings are that in the short run there is unidirectional granger causality running from income to attendance attendance to admission price and income to admission price while in the long run both admission price and income granger cause attendance

ranking unemployment duration and wages it explores the implication of one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time this assumption ranking is contrasted with the assumption of random hiring no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching the joint behaviour of unemployment the distribution of unemployment durations and wages are characterized the implication that the re employment prospects of employed workers were they to become unemployed are better than those of the currently unemployed appears to have been an important feature of european unemployment experience in the 1980 s this paper examines the effects of the composition of unemployment on wage determination it explores one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time we refer to this assumption as ranking and contrast it throughout to the assumption of random hiring or no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching we characterize the joint behaviour of unemployment the distribution of unemployment durations and wages ranking has a number of important implications first in addition to the obvious result that the exit rate from unemployment is a decreasing function of duration we show that the effect of duration is stronger the higher the rate of unemployment second with the wage depending on the distributions of prospective unemployment durations the presence of long term unemployed per se has little effect on wages third looking at the relation between the wage and the aggregate level of unemployment and comparing ranking to the case of no ranking the wage moves less with the level of unemployment but more with the change in unemployment put simply ranking and no ranking models show exactly the same aggregate unemployment slightly different long run responses of wages to unemployment and sharply different wage dynamics the paper is organized as follows section i characterizes the matching process and derives a matching function based on an urn ball process with vacancies as urns and applications by unemployed workers as balls thus the distribution of applications per vacancy depends on aggregate unemployment and vacancies vacancies with at least one acceptable application are filled when a vacancy receives more than one acceptable application firms use a rule to choose among applicants thus the rule determines who is hired but does not affect the number of hires section ii uses this matching function in a model of the labour market with continual job creation and destruction and characterizes the equilibrium values of unemployment vacancies and hires

reference dependent job search evidence from hungary we propose a model of job search with reference dependent preferences with loss aversion relative to recent income the reference point in this model newly unemployed individuals search hard since consumption is below their reference point over time though they get used to lower income and thus reduce their search effort in anticipation of a benefit cut their search effort rises again then declines once they get accustomed to the lower postcut benefit level the model fits the typical pattern of exit from unemployment even with no unobserved heterogeneity to distinguish between this and other models we use a unique reform in the unemployment insurance ui benefit path in 2005 hungary switched from a single step ui system to a two step system with overall generosity unchanged the system generated increased hazard rates in anticipation of and especially following benefit cuts in ways the standard model has a hard time explaining we estimate a model with optimal consumption endogenous search effort and unobserved heterogeneity the reference dependent model fits the hazard rates substantially better than plausible versions of the standard model including habit formation our estimates indicate a slow adjusting reference point and substantial impatience likely reflecting present bias jel codes d03 j64 j65

on repeated moral hazard with discounting in this paper we analyze optimal contracts in an infinitely repeated agency model in which both the principal and agent discount the future we show that there is a stationary representation of the optimal contract when the agent s conditional discounted expected utility is used as a state variable this representation reduces the multi period problem to a static variational problem which can be analyzed using standard variational techniques this reduction is used to obtain several properties of the contract

on optimal unemployment compensation abstract the design of an optimal unemployment compensation scheme is analyzed using a dynamic principal agent relationship between a risk neutral planner the principal and risk averse workers the agents where the planner s inability to observe workers job search efforts creates a moral hazard problem to design an implementable scheme we require that each agent is guaranteed a minimum level of expected discounted utility regardless of his past history in contrast with previous studies we find that the optimal contract is quite close to actual unemployment compensation schemes both qualitatively and quantitatively

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

cash on hand and competing models of intertemporal behavior new evidence from the labor market this paper presents new tests of the permanent income hypothesis and other widely used models of household behavior using data from the labor market we estimate the excess sensitivity of job search behavior to cash on hand using sharp discontinuities in eligibility for severance pay and extended unemployment insurance ui benefits in austria analyzing data for over one half million job losers we obtain three empirical results 1 a lump sum severance payment equal to two months of earnings reduces the job finding rate by 8 12 on average 2 an extension of the potential duration of ui benefits from 20 weeks to 30 weeks similarly lowers job finding rates in the first 20 weeks of search by 5 9 and 3 increases in the duration of search induced by the two programs have little or no effect on subsequent job match quality using a search theoretic model we show that estimates of the relative effect of severance pay and extended benefits can be used to calibrate and test a wide set of intertemporal models our estimates of this ratio are inconsistent with the predictions of a simple permanent income model as well as naive rule of thumb behavior the representative job searcher in our data is 70 of the way between the permanent income benchmark and credit constrained behavior in terms of sensitivity to cash on hand

how shortening the potential duration of unemployment benefits affects the duration of unemployment evidence from a natural experiment in this article we investigate the disincentive effects of shortening the potential duration of unemployment insurance ui benefits we identify these disincentive effects by exploiting changes in slovenia s unemployment insurance system a natural experiment that involved substantial reductions in the potential duration of benefits for four groups of workers plus no change in benefits for another group which served as a natural control we find that the change had a positive effect on the exit rate from unemployment to new jobs and other options for unemployment spells of various lengths and for several categories of unemployed workers
