recall in consumer search abstract this paper experimentally examines individual decision making in a sequential search environment when consumers sequentially search for the lowest price from a known distribution of prices theory suggests that decisions will be based on a comparison of the marginal cost of an additional search and the expected return from that search additionally in a finite time horizon model it is possible that individuals may choose to return to a price previously rejected exercise recall the data are used to determine if individuals do exercise recall the extent to which that option is chosen and to determine if the use of recall is dependent on the cost of search

which industry is greener an empirical study of nine industries in oecd countries abstract this study analyzed the relationship between the co2 emissions of different industries and economic growth in oecd countries from 1970 to 2005 we tested an environmental kuznets curve ekc hypothesis and found that total co2 emissions from nine industries show an n shaped trend instead of an inverted u or monotonic increasing trend with increasing income the ekc hypothesis for sector level co2 emissions was supported in the 1 paper pulp and printing industry 2 wood and wood products industry and 3 construction industry we also found that emissions from coal and oil increase with economic growth in the steel and construction industries in addition the non metallic minerals machinery and transport equipment industries tend to have increased emissions from oil and electricity with economic growth finally the ekc turning point and the relationship between gdp per capita and sectoral co2 emissions differ among industries according to the fuel type used therefore environmental policies for co2 reduction must consider these differences in industrial characteristics

income resources and electricity mix this paper presents evidence on a national level electricity ladder which sees countries transition toward coal and natural gas and finally nuclear power and modern renewables such as wind power for their electricity needs as they develop the extent to which countries climb the electricity ladder is dependent on energy endowments the results imply that the environmental implications of economic development differ in countries with different energy resource endowments an effective global carbon mitigation strategy will require developing countries to leapfrog the middle rungs of the electricity ladder

co2 emissions and income dynamics what does the global evidence tell us this paper analyzes the co evolution of two major determinants of social welfare namely income and carbon emissions in particular by using a distribution dynamics approach based on markov chains we investigate the shape and behavior of the joint distribution of per capita income and carbon dioxide emissions we arrive at several interesting conclusions especially in the context of international negotiations on climate change first evidence does not support theoretical models predicting the existence of a poverty environment trap specifically in the long run two main groups of countries will emerge poor versus polluting countries second the typical development path leads initially to high emission levels and subsequently to high income third the convergence process towards the stationary distribution is very slow finally for carbon emissions whenever it is observed the environmental kuznets curve seems to be only a transitory phenomenon

industrial pollution in economic development the environmental kuznets curve revisited abstract using new international data this paper tests the environmental kuznets curve ekc hypothesis for industrial water pollution we measure the effect of income growth on three determinants of pollution the share of industry in national output the share of polluting sectors in industrial output and end of pipe eop pollution intensities per unit of output in the polluting sectors we find that the industry share of national output follows a kuznets type trajectory but the other two determinants do not when combined our results imply rejection of the ekc hypothesis for industrial water pollution it rises rapidly through middle income status and remains roughly constant thereafter

ageing and unused capacity in europe is there an early retirement trap we address the issue of how early retirement may interact with limited use of financial markets in producing financial hardship later in life when some risks such as long term care are not insured we argue that the presence of financially attractive early retirement schemes in a world of imperfect financial and insurance markets can lead to an early retirement trap indeed europe witnesses many early retired individuals in financial distress in our analysis we use data on 10 european countries which differ in their pension and welfare systems in prevailing retirement age and in households access to financial markets we find evidence that an early retirement trap exists particularly in some southern and central european countries people who retired early in life are more likely to be in financial hardship in the long run our analysis implies that governments should stop making early retirement attractive let retirees go back to work improve access to financial markets and make sure long term care problems are adequately insured viola angelini agar brugiavini and guglielmo weber

asymmetric effects of the business cycle on carbon dioxide emissions abstract long term carbon dioxide emissions forecasts rely on the assumption that the economic growth rate is constant over long time horizons and exclude the business cycle thereby ignoring a fundamental component of the macroeconomy this paper considers how the business cycle affects emissions forecasts and shows the implicit assumption in current forecasts that the elasticity of emissions is constant with respect to gdp is wrong in the united states emissions fall more sharply when gdp declines than they rise when gdp increases this is partly due to a decrease in industrial energy intensity as gdp declines a simulation shows that accounting for the business cycle results in 5 lower cumulative emissions through 2050 relative to the baseline forecast

direct tests of the reservation wage property this paper provides the first direct experimental tests of the reservation wages predicted by finite horizon job search models previous indirect tests were based on search duration and search income the authors show that such indirect tests are weak by demonstrating that a naive rule performs essentially as well as the risk neutral model in predicting search duration in contrast direct tests of predicted reservation wages imply rejections of both the naive rule and the risk neutral model the general concave model survives direct tests with reservation wage data as does a specific logistic concave model copyright 1992 by royal economic society

another look at the income elasticity of non point source air pollutants a semiparametric approach in this paper a semiparametric model is used to examine the relationship between pollution and income for three non point source pollutants statistical tests reject the quadratic specification in favor of the semiparametric model in all cases however the results do not support the inverted u hypothesis for the pollution income relationship

retirement effects on health in europe what are the health impacts of retirement as talk of raising retirement ages in pensions and social security schemes continues around the world it is important to know both the costs and benefits for the individual as well as the governments budgets in this paper we use the survey of health ageing and retirement in europe share dataset to address this question in a multi country setting we use country specific early and full retirement ages as instruments for retirement behavior these statutory retirement ages clearly induce retirement but are not related to an individual s health exploiting the discontinuities in retirement behavior across countries we find significant evidence that retirement has a health preserving effect on overall general health our estimates indicate that retirement leads to a 35 percent decrease in the probability of reporting to be in fair bad or very bad health and an almost one standard deviation improvement in the health index while the self reported health seems to be a temporary impact the health index indicates there are long lasting health differences

quality matters the expulsion of professors and the consequences for phd student outcomes in nazi germany i investigate the effect of faculty quality on phd student outcomes to address the endogeneity of faculty quality i use exogenous variation provided by the expulsion of mathematics professors in nazi germany faculty quality is a very important determinant of short and long run phd student outcomes a one standard deviation increase in faculty quality increases the probability of publishing the dissertation in a top journal by 13 percentage points the probability of becoming a full professor by 10 percentage points the probability of having positive lifetime citations by 16 percentage points and the number of lifetime citations by 6 3

carbon dioxide emissions and economic growth panel data evidence from developing countries in this paper we test the environment kuznet s curve ekc hypothesis for 43 developing countries we suggest examining the ekc hypothesis based on the short and long run income elasticities that is if the long run income elasticity is smaller than the short run income elasticity then it is evident that a country has reduced carbon dioxide emissions as its income has increased our empirical analysis based on individual countries suggests that jordan iraq kuwait yemen qatar the uae argentina mexico venezuela algeria kenya nigeria congo ghana and south africa approximately 35 per cent of the sample carbon dioxide emissions have fallen over the long run that is as these economies have grown emissions have fallen since the long run income elasticity is smaller than the short run elasticity we also examine the ekc hypothesis for panels of countries constructed on the basis of regional location using the panel cointegration and the panel long run estimation techniques we find that only for the middle eastern and south asian panels the income elasticity in the long run is smaller than the short run implying that carbon dioxide emission has fallen with a rise in income

economic development and co2 emissions a nonparametric panel approach we examine the empirical relation between co2 emissions per capita and gdp per capita during the period 1960 1996 using a panel of 100 countries relying on the nonparametric poolability test of baltagi et al baltagi b h hidalgo j li q 1996 a nonparametric test for poolability using panel data journal of econometrics 75 345 367 we find evidence of structural stability of the relationship we then specify a nonparametric panel data model with country specific effects estimation results show that this relationship is upward sloping nonparametric specification tests do not reject monotonicity but do reject the polynomial functional form which leads to the environmental kuznets curve in several studies

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

testing the kuznets curve hypothesis for qatar a comparison between carbon dioxide and ecological footprint abstract this paper explores the validity of the environmental kuznets curve ekc using two different environment indicators the carbon dioxide emissions co2 and the ecological footprint ef in qatar over the 1980 2011 period to this end we investigate the impact of real gross domestic product rgdp the square of rgdp the energy use the financial development and the trade openness on the co2 emissions and the ef we employ the autoregressive distributed lag ardl model with the presence of unknown structural breaks in order to study short run and long run elasticity between the variables the findings infer that there is a long run relationship among the selected variables with a shift in the cointegration vector in 1991 and 2000 the empirical result indicates that the inverted u shaped hypothesis is not valid in qatar when we use the co2 emissions whereas the inverted u shaped held when using the ef furthermore the error correction results confirm that the convergence towards the long run equilibrium will mostly occur within one year after a short run shock generally the findings suggest that qatar should invest more in efficient energy and continue sustained its growth moreover more efforts are needed for diversification particularly in technology intensive and environment friendly industries to improve environmental quality

testing for convergence in carbon dioxide emissions using a bayesian robust structural model we address international convergence in carbon dioxide emissions per capita and per value added derived from emission inventories based on production and consumption patterns we propose a bayesian structural model that accounts for heteroscedasticity and endogeneity between emissions and economic growth and tests for the existence of group specific convergence via shrinkage priors we find evidence for country specific conditional convergence in all emission inventories implying a half life of 2 7 3 1 years for production based emissions and 3 6 4 7 years for consumption based emissions when testing for global convergence without allowing for individual specific convergence paths the half life of hbox co 2 per capita increases to 15 26 years whereas emission intensities show a half life of 44 45 years our results highlight the current incompatibility between emission targets and economic growth and the need for faster diffusion of green technologies moreover there is no evidence for specific convergence dynamics in the european union the oecd or the countries that are subject to binding emission constraints specified in the kyoto protocol the institutional frameworks implemented in industrialized countries did not induce faster convergence among developed economies

a multiscale reassessment of the environmental kuznets curve for energy and co2 emissions abstract this paper investigates the environmental kuznets curve hypothesis for total primary energy supply and co2 from fuel combustion over the period 1971 2015 our analysis has two distinguishing features firstly it adopts a robustness approach by a using both parametric and semi parametric methods and b analysing different geographical scales secondly it strictly adheres to the ekc narrative by a not using control variables and b taking energy and co2 in absolute rather than in per capita terms which is consistent with the fact that nature cares about absolute pressures we show how evidence for ekc changes depending on the model specification the sample and the used variables hence this paper contributes to explaining why the literature on the ekc gives mixed results the multiscale perspective and some theoretical considerations however tell how to perform the analysis appropriately thus we can affirm that both for co2 and energy the fragile evidence of ekc that was emerging at the end of the last century has vanished with the new wave of globalization there is only evidence of decreasing elasticities for very high income countries interestingly the great recession might have produced structural reductions in tpes and co2 in the affected countries finally the case of germany which shows ekc patterns indicates that active energy policies can reduce energy and co2 without harming the economy

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

identifying reduced form relations with panel data the case of pollution and income abstract in this paper we propose a solution to the non robustness that plagues the estimation of inverted u shaped relationships using panel data such as the relation between pollution and income when dependent and independent variable like pollution and income are both time related separating the effect of the independent variable from time effects brings about a fundamental identification dilemma the imposition of restrictions on the controls might drive the shape of the relationship between the dependent pollution and independent income variables our solution consists of imposing the very weak constraint that arbitrary cross sectional units have the same relationship we apply our methodology to two widely studied cases namely so 2 and co 2 emissions interestingly our estimates are insensitive to the required subjective choices but also strongly differ from the literature so far we find consistent positive income effects for both cases and time effect estimates with a clear u shaped trend for so 2 emissions but only slightly so for co 2 emissions

on the relationships between co2 emissions energy consumption and income the importance of time variation abstract the environment that governs the relationships between energy consumption carbon dioxide co2 emissions and gross domestic product gdp in the g7 countries changes over time due to variations in economic growth regulatory policy and technology using a novel approach that may detect causalities when the time constant hypothesis is rejected we find significant time varying granger causalities among the variables under consideration there is bidirectional causality between gdp and energy consumption for japan unidirectional causality running from gdp to energy consumption for italy and unidirectional causality running from energy consumption to gdp for the resource country canada moreover the results also show a bidirectional time varying causality between energy consumption and co2 emissions for the united states and causality from energy consumption to co2 emissions for france finally while we find significant time varying causalities running from gdp to co2 emissions for italy and japan the finding of inverted n shaped curves italy and japan lends no support to the traditional environmental kuznets curve ekc hypothesis for these countries it implies that environmental policy and economic growth should go hand in hand other policy implications of the empirical results have been proposed

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

the environmental kuznets curve ekc theory part a concept causes and the co2 emissions case abstract the main purpose of this study is to capture the main features of the environmental kuznets curve ekc concept according to the ekc theory the process of economic growth is expected eventually to limit the environmental degradation created in the early stages of development the ekc concept leads many researchers from the early 1990s to assume that each economy should focus on its growth and any environmental problems will be eventually eliminated by the process of economic growth several studies attempt to test empirically the ekc hypothesis using data on many countries and examining various types of environmental degradation while other studies examine the underlying factors that may drive such a relationship this article reviews the evolution of the ekc concept and the possible causes of an ekc pattern like the distribution of income the international trade pollution haven hypothesis structural changes technical progress and improvements in energy efficiency institutions and governance and consumer preferences as co2 emissions are a pollutant with global effects several studies deal with the possible ekc pattern for co2 emissions and these studies are discussed separately the various critiques on the ekc concept are reviewed in the second article of this work

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

the determinants of atmospheric so2 concentrations reconsidering the environmental kuznets curve this analysis explores the effects of income and the spatial intensity of economic activity on the atmospheric concentration of sulfur dioxide the results indicate that there is a u shaped relation between income and atmospheric concentration of so2 and an inverted u shaped relation between the spatial intensity of economic activity and so2 concentrations these results suggest that the spatial intensity of economic activity rather than income provides the impetus for policies and technologies that reduce so2 emissions based on this result the atmospheric concentration of so2 in developing nations may decline faster than indicated by previous analyses the potential for this decline depends on the rate at which income grows relative to population the trade off between the effects of income gains and the spatial intensity of economic activity on the atmospheric concentration of so2 is consistent with the notion that some environmental problems can be ameliorated by slowing population growth and increasing income levels

environmental kuznets curve for co2 in canada abstract according to the environmental kuznets curve hypothesis the relationship between per capita gdp and per capita pollutant emissions has an inverted u shape this implies that past a certain point economic growth may actually be profitable for environmental quality most studies on this subject are based on estimating fully parametric quadratic or cubic regression models while this is not technically wrong such an approach somewhat lacks flexibility since it may fail to detect the true shape of the relationship if it happens not to be of the specified form we use semiparametric and flexible nonlinear parametric modeling methods in an attempt to provide more robust inferences we find little evidence in favour of the environmental kuznets curve hypothesis our main results could be interpreted as indicating that the oil shock of the 1970s has had an important impact on progress towards less polluting technology and production

is there an environmental kuznets curve for deforestation abstract this paper examines the relationship between deforestation and gross domestic product gdp per capita in particular whether an inverted u relationship indicative of worsening then improving deforestation exists between them we note that previous work has used models with restrictive assumptions and recommend a more flexible random coefficients specification which allows for a greater degree of cross country heterogeneity empirical results using data for 76 developing countries between 1961 1992 suggest that the inverted u shaped relationship observed in other studies does not appear to be an empirical regularity with our less restrictive specification statistical tests indicate that this specification is supported by the data we argue that such results are not surprising in view of the wide diversity of physical and social characteristics that exist across countries

a test for parameter homogeneity in co2panel ekc estimations this paper casts doubt on empirical results based on panel estimations of an inverted u relationship between per capita gdp and pollution using a new dataset for oecd countries on carbon dioxide emissions for the period 1960 1997 we find that the crucial assumption of homogeneity across countries is problematic decisively rejected are model specifications that feature even weaker homogeneity assumptions than are commonly used furthermore our results challenge the existence of an overall environmental kuznets curve for carbon dioxide emissions

the personal discount rate evidence from military downsizing programs the military drawdown program of the early 1990s provides an opportunity to obtain estimates of personal discount rates based on large numbers of people making real choices involving large sums the program offered over 65 000 separatees the choice between an annuity and a lump sum payment despite break even discount rates exceeding 17 percent most of the separatees selected the lump sum saving taxpayers 1 7 billion in separation costs estimates of discount rates range from 0 to over 30 percent and vary with education age race sex number of dependents ability test score and the size of payment

environmental performance corruption and economic growth global evidence using a new data set abstractthis study investigates the relationship between environmental performance corruption and economic growth using panel data of 87 countries covering the period from 2002 to 2012 the environmental performance index is used for the first time to evaluate the environmental quality on economic growth by employing both static and dynamic panel models we find that environmental performance is positively related to economic growth and is more significant in non organization for economic cooperation development oecd countries moreover when corruption is incorporated the empirical estimation results indicate that although lower corruption helps economic growth in non oecd countries the negative coefficients of the three interactive terms show that the positive effect of environment performance on economic growth will drop while greater environmental performance combined with natural resource abundance inevitably leads to inefficient bureaucracies and hence disadvantageous economic growth as

financial development environmental quality trade and economic growth what causes what in mena countries this paper examines the relationship between financial development co2 emissions trade and economic growth using simultaneous equation panel data models for a panel of 12 mena countries over the period 1990 2011 our results indicate that there is evidence of bidirectional causality between co2 emissions and economic growth economic growth and trade openness are interrelated i e bidirectional causality feedback hypothesis is validated between trade openness and financial development neutrality hypothesis is identified between co2 emissions and financial development unidirectional causality running from financial development to economic growth and from trade openness to co2 emissions is identified our empirical results also verified the existence of environmental kuznets curve these empirical insights are of particular interest to policymakers as they help build sound economic policies to sustain economic development and to improve the environmental quality

the environmental kuznets curve semi parametrically revisited this paper re examines the existence of an environmental kuznets curve ekc across countries using a semi parametric regression estimator which places no restrictions on the functional form our results using cross country panel data on sulfur and carbon dioxide strongly suggest that the relationship between wealth and environmental degradation is not bell shaped as suggested by an ekc rather that there is a positive link for the very poorest countries and no clear relationship for richer countries

applying real options analysis to assess cleaner energy development strategies abstract the energy industry accounts for the largest portion of co 2 emissions is facing the issue of compliance with the national clean energy policy the methodology for evaluating the energy mix policy is crucial because of the characteristics of lead time embedded with the power generation facilities investment and the uncertainty of future electricity demand in this paper a modified binomial model based on sequential compound options which may account for the lead time and uncertainty as a whole is established and a numerical example on evaluating the optional strategies and the strategic value of the cleaner energy policy is also presented it is found that the optimal decision at some nodes in the binomial tree is path dependent which is different from the standard sequential compound option model with lead time or time lag concept the proposed modified binomial sequential compound real options model can be generalized and extensively applied to solve the general decision problems that deal with the long lead time of many government policies as well as capital intensive investments

carbon intensity and economic development 1962 1991 a brief exploration of the environmental kuznets curve the relationship between national carbon dioxide emissions intensity co2 emitted per unit of gross domestic product and level of economic development has changed from essentially linear in 1962 to strongly curvilinear in 1991 the inverted u curve reached statistical significance briefly in the early 1970s and increasingly since 1982 this is the result not of groups of countries passing through stages of development but of efficiency improvements in a small number of wealthy countries combined with worse performance in poor and middle income countries the curvilinear relation is deepening and is likely to persist due to constraints on poorer countries in the world economy

carbon dioxide emissions and economic growth an assessment based on production and consumption emission inventories working with a new dataset on comparable global co2 production and consumption inventories spanning the 1997 2011 period we investigate the relationship between real gross domestic product gdp per capita and co2 emissions per capita associated with both production and consumption activities by including linkages between production based emissions in one country and final consumption in another via cross border value chains we focus on the entire carbon chain we estimate polynomial and threshold models accounting for reverse causality and identification problems we find that the income elasticity for both inventories is regime dependent and reflects small carbon efficiency gains from economic development carbon footprints show larger income elasticities while national policy instruments targeting production can clearly be circumvented by carbon embodied in intermediate trade this implies problems of environmental sustainability that may require consumption based policy instruments

assessing the relationship between economic and ecological performance distinguishing system levels and the role of innovation in this article we critically discuss the different perspectives that are currently in use for assessing the relationship between ecological and economic performance based on a review of the literature we propose that research up till now has made use of four distinct system boundaries the firm markets production and consumption systems and economic systems making these boundaries explicit is helpful in interpreting the mixed results that have been obtained we describe the consequences of the choice for each of these system boundaries and look at implications for innovation we also argue that the production and consumption system boundary offers potential for further advances in the field and deserves more attention in future research

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

why do most italian youths live with their parents intergenerational transfers and household structure more than 80 of italian men aged 18 30 live with their parents we argue that one contributing factor to this remarkably high rate of cohabitation is parents tastes for co residence in order to investigate the role of parental preferences we estimate the effect of exogenous changes in parental income on rates of cohabitation in italy using shiw micro data from 1989 to 2000 the key econometric issue is the potential endogeneity of parental income in order to identify a source of exogenous variation in parental income we use changes in fathers retirement age induced by the 1992 reform of the italian social security system as an instrumental variable for parental income by raising retirement age this reform forced some fathers to remain in the labour market longer than they would have otherwise therefore raising their disposable income we use a two sample instrumental variable tsiv strategy our tsiv estimates indicate that a rise in parents income significantly raises the children s propensity to live at home a 10 increase in annual parental income results in approximately a 10 rise in the proportion of boys living with their parents although we cannot definitely rule out alternative interpretations these results are consistent with our hypothesis that cohabitation is a normal good for italian parents

estimating country specific environmental kuznets curves from panel data a bayesian shrinkage approach designing an efficient global climate policy turns out to be a difficult yet crucial task since there are noteworthy cross country differences in energy and carbon intensities in this article the environmental kuznets curve ekc hypothesis is tested for carbon dioxide co2 emissions and as a modelling technique the iterative bayesian shrinkage procedure is employed to handle the cross country differences the results suggest that first the ekc hypothesis is rejected for 47 out of the 51 countries considered when the heterogeneity in countries energy efficiencies and cross country differences in the co2 emissions trajectories are accounted for second a classification of the results with respect to the development levels of the countries concerned reveals that the emergence of an overall inverted u shaped curve is due to the fact that in high income countries increase in gross domestic product gdp decreases emissions while in low income countries emissions and gdp are positively correlated

the retirement consumption puzzle evidence from a regression discontinuity approach in this paper we investigate the size of the consumption drop at retirement in italy we use micro data on food and total non durable household spending covering the period 1993 2004 and evaluate the change in consumption that accompanies retirement by exploiting the exogenous variability in pension eligibility to correct for the endogenous nature of the retirement decision we take a regression discontinuity design approach and make the identifying assumption that consumption would be the same around the threshold for pension eligibility if individuals would not retire we check in our data that a non negligible fraction of individuals retire as soon as they become eligible and estimate at 9 8 the part of the non durable consumption drop that is associated with retirement induced by eligibility we show that such fall is not driven by liquidity problems for the less well off in the population and can be accounted for by drops in goods that are work related expenses or leisure substitutes however we also show that retirement induces a significant drop in the number of grown children living with their parents and this can account for most of the retirement consumption drop

ageing cognitive abilities and retirement we investigate the relationship between ageing cognitive abilities and retirement using the survey on health ageing and retirement in europe share a household panel that offers the possibility of comparing several european countries using nationally representative samples of the population aged 50 the human capital framework suggests that retirement may cause an increase in cognitive decline since after retirement individuals lose the market incentive to invest in cognitive repair activities our empirical results based on an instrumental variable strategy to deal with the potential endogeneity of retirement confirm this key prediction they also indicate that education plays a fundamental role in explaining heterogeneity in the level of cognitive abilities

the nature of co2 emission kuznets curve this paper reveals that co2 emission kuznets curve merely reflects the peak theory of energy intensity the situation of real energy use should be used as a fundamental stone for both energy and environmental policy making

distance to retirement and older workers employment the case for delaying the retirement age this paper presents empirical evidence and a theoretical foundation in favor of the view that the retirement age decision affects older workers employment prior to retirement to the extent that there are search frictions on the labor market the return on jobs is determined by their expected duration the time to retirement is then key to understanding older workers employment countries with a retirement age of 60 are indeed characterized by lower employment rates for workers aged 55 59 based on the french labor force survey we show that the likelihood of employment is significantly affected by the distance to retirement in addition to age and other relevant variables we then extend mccall s job search model by explicitly integrating life cycle features with the retirement decision using simulations we show that the distance effect in interaction with the generosity of unemployment benefits and the depressed demand for older workers explains the low rate of employment just before the eligibility age for the social security pension finally we show that implementing actuarially fair schemes not only extends the retirement age but also encourages a more intensive job search by older unemployed workers jel j22 j26 h55

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

the effect of pension reform on pension benefit expectations and savings decisions in japan using the japanese study of aging and retirement jstar which is a new japanese panel survey of people aged 50 and over we find that more japanese in their early 50s expect their level of public pension benefits to decline compared with those in their late 50s and early 60s we also find that recent pension reforms that raised the pensionable age affected the japanese population by increasing the age at which they expect to claim their benefits by almost the exact same amount as the increase in the pensionable age the reforms have also decreased the population s expectations about receiving public pension benefits although this effect is not necessarily significant we also find evidence that anxiety about the public pension programme s future increases private savings

economic search an experimental study this paper presents results of experiments designed to test several of the hypotheses present in the theoretical literature on optimal economic search first we test whether the subjects searchers actually search for wages in ways that are consistent with setting an optimal reservation wage we then proceed to determine experimentally the effects of risk aversion increased search costs changes in risk brought about by a mean preserving transformation of the distribution of wage offers the presence or absence of recall the existence of a finite horizon and the searcher s state of knowledge about the underlying distribution of wages in general we find that the searchers exhibit behavior that is consistent with that predicted by theory differences between risk neutral and risk averse searchers are found and the responses of both groups to changes in search costs in the degree of risk or in the state of knowledge are consistent with theoretical predictions

gdp and environment pressure the role of energy in latin america and the caribbean abstract this paper analyzes the relationship between economic growth and energy consumption for a sample of 21 latin american and caribbean countries during the 1970 2007 period the investigation is made on the bases of the energy environmental kuznets curve eekc hypothesis using a panel data analysis energy consumption at aggregate level is used as an indicator of human environmental pressure and gdp per capita as an indicator of economic activity based in a cointegration approach our results does not support the existence of a stable long run relationship between the series rejecting the validity of such hypothesis for the selected sample over the 1970 2007 period

modeling the nexus between carbon dioxide emissions and economic growth the effects of economic growth on the environment have received increased attention as global warming and other environmental problems become more serious many empirical studies explain the nexus between carbon dioxide emissions and economic growth with such models as the environmental kuznets curve ekc theory however the assumptions of these models have never received strict verification with a large available data set and therefore may not be appropriate to describe the relationship in this study the nexus is modeled for 67 countries from 1971 to 2010 using a novel symbolic regression method from the experimental results several conclusions as follows could be reached firstly there is no universal model fitting every country and symbolic regression could discover a set of reasonable models for a specific country or region secondly four models including the inverted n shaped m shaped inverted u shaped and monotonically increasing are frequently found without domain experts intervention in these countries whereas the m shaped model has received little attention in previous studies but exhibits promising performance thirdly the relationship is diversified due to the difference of regions and economic development where developed countries generally follow the inverted n shaped and m shaped models to explain the relationship whereas developing countries are more likely to refer to the inverted n shaped inverted u shaped and monotonically increasing models finally several policy suggestions are presented

economic growth energy and environmental kuznets curve the aim of this study is to investigate the relationship between income and carbon dioxide co2 emissions in the context of the environmental kuznets curve ekc which posits the existence of an inverted u shape relationship between environmental degradation and economic development for this purpose two empirical models are examined for both models the relationship between per capita income and per capita co2 emissions and the relationship among per capita income per capita energy use and per capita co2 emissions are analyzed respectively between 1980 and 2010 using the panel data estimation techniques with the application of driscoll kraay standard errors yet for the first model data are analyzed for 26 oecd countries with high income levels while for the second model data are examined for 52 emerging countries the results of both models show that n shape and an inverted n shape relationship for cubic functional form are observed thus the results do not support the ekc hypothesis which implies that environmental degradation cannot be solved automatically by economic growth

searching for a kuznets curve in environmental efficiency using kernel estimation abstract the paper constructs environmental efficiency indexes for a sample consisting of high and low income countries using nonparametric production frontier techniques and then establishes an environmental kuznets relationship for environmental efficiency by nadaraya watson kernel estimation methodology

does postponing minimum retirement age improve healthy behaviors before retirement evidence from middle aged italian workers abstract by increasing the residual working horizon of employed individuals pension reforms that rise minimum retirement age can affect individual investment in health promoting behaviors before retirement using the expected increase in minimum retirement age induced by a 2004 italian pension reform and a difference in differences research design we show that middle aged italian males affected by the reform reacted to the longer working horizon by increasing regular exercise with positive consequences for obesity and self reported satisfaction with health

sustainable economic development and the environment theory and evidence the relationship between growth and pollution is studied through a vintage capital model where new technologies are more environmentally friendly we find that once the optimal scrapping age of technologies is reached an economy may achieve two possible cases of sustainable development one in which pollution falls and another in which it stabilizes or a catastrophic outcome where environmental quality reaches its lower bound the outcome will depend on countries investment path and their propensity to innovate in environmentally clean technologies both of which are likely to differ across economies empirical results using long time series for a number of developed and developing countries indeed confirm heterogenous experiences in the pollution output relationship

richer and cleaner a study on carbon dioxide emissions in developing countries abstract the climate change debate has drawn attention to the problem of greenhouse gases emissions into the atmosphere one of the most important issues in the policy debate is the role that should be played by developing countries in joining the commitment of developed countries to reduce ghg emissions and particularly co2 emissions this debate calls into play the relationship between energy consumption co2 emissions and economic development in this paper we use a panel data model for 110 world countries to estimate the relationship between co2 emissions and gdp and to produce emission forecast the paper contains three major results i the empirical relationship between carbon dioxide and income is well described by non linear gamma and weibull specifications as opposed to more usual linear and log linear functional forms ii our single equation reduced form model is comparable in terms of forecasted emissions with other more complex less data driven models iii despite the decreasing marginal propensity to pollute our forecasts show that future global emissions will rise the average world growth of co2 emissions between 2000 and 2020 is about 2 2 yr while that of non annex 1 countries is posted at 3 3 yr

nonlinearities and heterogeneity in environmental quality an empirical analysis of deforestation we use a panel data set of 59 developing countries over the 1972 1994 period to study the deforestation process relying on both parametric and semiparametric models we examine nonlinearities and heterogeneity in the deforestation process we first study the existence of an environmental kuznets curve ekc and then analyze determinants of deforestation our data sample provides no evidence of an ekc we also find that political institution failures may worsen the deforestation process in developing countries

do countries influence neighbouring pollution a spatial analysis of the ekc for co2 emissions abstract by considering spatial relationships this study aims to analyse to what extent per capita co2 emissions are determined by renewable energy consumption the share of the services sector in gdp energy intensity and real per capita income a panel data set composed of 173 countries over the 1990 2014 period is used to estimate an environmental kuznets curve ekc augmented by neighbouring per capita income and energy intensity both standard and spatial forms are estimated for seven different sets of countries to assess the robustness of the results finally several forecasts are performed to verify global sustainability and to provide some policy suggestions for the period 2015 2100 the empirical results indicate that i most areas support the standard ekc ii there seems to be an inverted u shaped relationship between neighbouring per capita income and national per capita emissions in europe asia and the world as a whole iii neighbouring energy intensity increases national per capita emissions and iv forecasts show that economic growth will accelerate climate change however a steady annual growth in renewable energy consumption and a steady decrease in energy intensity both close to 2 5 may guarantee environmental sustainability prior to 2100

co2 response to business cycles new evidence of the largest co2 emitting countries in asia and the middle east abstract this paper examines co2 response to business cycles of six large co2 emitting countries in asia and the middle east namely china india japan iran saudi arabia and south korea by using a markov switching autoregressive models emissions are cyclically more volatile than gdp in a typical country except for iran it is observed that emissions are procyclical in all studied countries except for india but the elasticity of the emission with respect to gdp significantly depends on regimes in japan and south korea elasticity of co2 emissions with respect to gdp during expansions is significantly larger than during recessions in iran and saudi arabia elasticity of co2 emissions with respect to gdp is significantly smaller than 1 but the co2 emissions response to gdp during recessions is significantly larger than during expansions in china elasticity of co2 emissions to gdp is significantly larger than 1 during recessions and normal and co2 emissions response to gdp during recessions is significantly larger than during expansions these results have implications for environmental policy makers the optimal response of pollution abatement costs in japan and south korea should be high low during expansions recessions and in china iran and saudi arabia should be low high during expansions recessions after releasing a positive productivity shock

taking the u out of kuznets a comprehensive analysis of the ekc and environmental degradation unlike most environmental kuznets curve ekc studies which focus on narrow measures of pollution as proxies for environmental quality we test the validity of the ekc using the ecological footprint ef a more comprehensive measure of environmental degradation we find no empirical evidence of an ekc relationship between the ef and economic development and only limited support for such a relationship among the components of the ef in addition we discover that energy is largely responsible for the lack of an ekc relationship and that energy consumption levels would have to be cut by over 50 in order for a statistically significant ekc relationship to emerge from the data overall these results suggest that growth alone will not lead to sustainable development

retirement expectations pension reforms and their impact on private wealth accumulation abstract we estimate the effect of pension reforms on households expectations of retirement outcomes and private wealth accumulation decisions exploiting a decade of intense italian pension reforms as a source of exogenous variation in expected pension wealth the survey of household income and wealth a large random sample of the italian population elicits expectations of the age at which workers expect to retire and of the ratio of pension benefits to pre retirement income between 1989 and 2002 we find that workers have revised expectations in the direction suggested by the reform and that there is substantial offset between private wealth and perceived pension wealth particularly by workers that are better informed about their pension wealth

time to burn calories the impact of retirement on physical activity among mature americans abstract physical activity is crucial for maintaining and improving health especially at advanced ages while retirement increases the amount of time available for physical activity there is only limited evidence regarding the causal effect of retirement on recommended levels of physical activity addressing this gap in the literature we use data from the u s health and retirement study to estimate the causal impact of retirement on meeting the federal government s 2008 physical activity guidelines for americans using official early and normal retirement ages as instruments for retirement our causal iv analyses suggest significant positive effects of retirement on meeting the guidelines these effects are robust with regard to the treatment of unobserved individual specific heterogeneity the measurement of guideline compliance the definition of retirement and respondents health insurance status we also show that the effects of retirement on physical activity are larger for persons with higher levels of education and wealth

the environmental kuznets curve does one size fit all abstract this paper uses a new panel data set on state level sulfur dioxide and nitrogen oxide emissions from 1929 1994 to test the appropriateness of the one size fits all reduced form regression approach commonly used in the environmental kuznets curve literature empirical results provide initial evidence that an inverted u shape characterizes the relationship between per capita emissions and per capita incomes at the state level parameter estimates suggest however that previous studies which restrict cross sections to undergo identical experiences over time may be presenting statistically biased results

a consumption based approach to environmental kuznets curves using the ecological footprint indicator recent research suggests that consumption based measures offer an insightful perspective on the debate on the relationship between economic growth and the environment in this article we deepen the

consumer search behavior and sunk costs abstract this paper presents the results of four economic experiments involving 41 undergraduate students who were assigned the task of searching for the lowest price from a known distribution of prices economic theory predicts that individuals should continue to draw until the expected gain of another search is less than the marginal search cost additionally once individuals have made a draw and then continued they should never return to a price drawn earlier exercise recall both of these predictions are tested in the paper and the results show that behavior is not always consistent with them it appears that individuals are making decisions based on the total return from searching rather than simply the marginal return from another draw

sunk costs and travel cancellation focusing on temporal cost abstract tourism products differ from ordinary retail products in terms of the spatial and temporal separation between the purchase and experiencing the product despite its importance temporal separation has not drawn much attention in tourism research the main objective of this study is to understand the effects of temporal sunk costs on potential travelers cancellation intentions in addition to monetary sunk costs the results of this study suggested the possibility that temporal costs can be converted into monetary costs but the conversion relationship may not be linear this study also indicated that travelers intentions to cancel a travel product decreased as the temporal and monetary sunk costs increased further prior experience moderated the relationship when temporal sunk costs were involved suggesting that repeat visitors intentions to cancel their reservations are more influenced by temporal sunk costs than first time visitors further discussion and implications are provided in the main body of this paper

is there an environmental kuznets curve for sulfur abstract most existing estimates of the environmental kuznets curve ekc for sulfur which use samples of mainly high income countries indicate a maximum emissions turning point at middle to lower high income levels of gdp per capita we use a larger and more globally representative sample than previous sulfur ekc studies we find that sulfur emissions per capita are a monotonic function of income per capita when we use a global sample and an inverted u shape function of income when we use a sample of high income countries a model estimated in first differences results in a monotonic ekc when estimated with both high income and global samples reductions in emissions are time related rather than income related

aspects of governance and hbox co _2 co 2 emissions a non linear panel data analysis the reduction of hbox co 2 emissions has been at the centre of worldwide debates on environmental issues though its inclusion as one of the millennium development goals mdgs by the united nations has changed the focus of relative literature among many one of the world bank s recipes to achieve a higher position toward mdgs has been to undertake reforms for a better governance while the majority of researches focus has been on one single aspect and its relationship with the environment some studies have simultaneously considered two governance dimensions in this paper we focus on the role of several aspects of governance on hbox co 2 emissions this provides us with a chance to explore the possible impacts of all aspects of governance on a more direct measure of emissions that is different to previous researches which have focused on the indirect transmission and considered the maximum of two using the iv method within panel data analysis we show that only one single aspect of governance control of corruption has a negative significant effect on hbox co 2 emissions and its effect has a non linear relationship the non linearity exists in both parametric and nonparametric analysis after controlling for endogeneity

correlation analysis of co 2 emissions material stocks and economic growth nexus evidence from chinese provinces abstract a better understanding of the economy material emissions nexus is fundamental in order to reveal the interactions between human development and the natural environment and more importantly to design integrated de carbonization and de materialization policies in this paper we conducted a decoupling analysis of fossil fuel induced co2 emissions and in use material stocks in infrastructure to economic growth at the provincial level in china and investigated the trilateral causal relationships among the three indicators the results show that the average elasticity of co2 emissions and material stocks to economic growth was smaller than 1 representing a status of relative decoupling however in many less developed provinces in central and western china we observed increasing trends of elasticity in the past three decades which suggest their economic growth became more tightly linked to co2 emissions and the accumulation of material stocks granger tests suggest that in the long run there existed a unidirectional causality running from co2 emissions economic growth and urbanization to material stocks in the short run a bi directional causality between co2 emissions and economic growth and a unidirectional causality from material stocks to co2 emissions were detected policy implications for the de carbonization and de materialization transition include enhancing renewable energy utilization upgrading industries to less carbon intensive ones developing compact cities prolonging the lifespan of infrastructure and strengthening the life cycle carbon management of infrastructure

regional differences in the dynamic linkage between co2 emissions sectoral output and economic growth environmental degradation measured by co2 emissions is a significant challenge to sustainable economic development owing to significant differences in the empirical relationship between the economic growth and co2 emissions and policies adopted by different countries to overcome the challenge are not decisive this study aims to generalize our knowledge about the relationship between co2 emissions per capita and economic growth across the world for 1980 2009 periods besides it explores whether the transformation of different economies e g agrarian to industrial and industrial to sophisticated service economy over the past few decades yielded any significant positive impact towards sustainable economic development by reducing the level of co2 emission empirical results suggest that i except for high income countries environmental kuznets curve ekc is a general phenomenon across the world and ii the transformation of different economies towards a service economy has produced more pollution in high income countries and less pollution in low and middle income countries

energy consumption and income a semiparametric panel data analysis this paper proposes a semiparametric analysis for the study of the relationship between energy consumption per capita and income per capita for an international panel dataset it shows little evidence for the existence of an environmental kuznets curve for energy consumption energy consumption increases with income for a majority of countries and then stabilizes for very high income countries neither changes in energy structure nor macroeconomic cycle technological change have significant effect on energy consumption
