regional earnings differences in great britain evidence from the new earnings survey hemmings p j 1991 regional earnings differences in great britain evidence from the new earnings survey reg studies 25 123 133 previous analysis comparing earnings between regions of great britain has concentrated upon the earnings of male employees using a large micro data base this paper takes a broader approach by examining earnings differences for female and part time employees as well as male employees human capital models are used to explain the variation in earnings in terms of characteristic differences and reward effects a restricted model with no regional element is tested against more general models which allow for regional variation in the constant term only and in both the constant and coefficients of the equations the most general model indicates that equations for the earnings of males display greater regional heterogeneity than those for females whilst the south east of england is the most distinctive region in terms of employee characteristics and in the returns to those e

double dividend effectiveness of energy tax policies and the elasticity of substitution a cge appraisal there is a considerable body of literature that has studied whether or not an adequately designed tax swap whereby an ecotax is levied and some other tax is reduced while keeping government income constant may achieve a so called double dividend that is an increase in environmental quality and an increase in overall efficiency arguments in favor and against are abundant our position is that the issue should be empirically studied starting from an actual non optimal tax system structure and by way of checking the responsiveness of equilibria to revenue neutral tax regimes under alternate scenarios regarding technological substitution with the use of a cge model we find that the most critical elasticity for achieving a double dividend is the substitution elasticity between labor and capital whereas the elasticity that would generate the highest reduction in carbon dioxide emissions is the substitution elasticity among energy goods

the north south divide questions of existence and stability this paper investigates the relationship between regional earnings and unemployment by use of information primarily from the general household surveys of 1975 and 1982 conventional earnings functions are augmented to capture the effects of the level and duration of unemployment and of regional differences in living costs in common with previous studies the authors find personal characteristics and the occupation or industry of employment to be important in earnings determination in this paper however they generally find that although higher unemployment is associated with reduced regional earnings ceteris paribus long term unemployment has little influence in regional earnings determination copyright 1990 by royal economic society

joint confidence intervals for income shares and lorenz curves in a recent paper beach and davidson 1983 extended the principles of statistical inference to lorenz curves and income shares by establishing the asymptotic distribution and covariance structure of a vector of lorenz curve ordinates corresponding to a set of quantile abscissae one can thus use the lorenz curve and income shares no longer just as descriptive devices for summarizing distribution information but now also as analytical tools for comparing alternative distributions and carrying out conventional statistical inference on them it would clearly be desirable however to extend and complement this work by providing a method for computing a set of joint confidence intervals about these income shares and for illustrating graphically a joint confidence band about a set of estimated lorenz curve ordinates the present paper provides a new and simple technique for doing this when analyzing differences between sets of income shares or lorenz curves one typically wants to elicit more detailed information than is provided by a standard joint chi square test on the overall set of shares that is when the hypothesis of two sets of shares being the same is rejected we generally want to know further which particular differences in shares are different from zero and of these nonzero differences which are positive and which negative savin 1980 a natural way of providing such information is through multiple comparison procedures developed in this paper in a recent work richmond 1982 has developed a general method of finding multiple comparison intervals that is particularly suited to the present problem and in this situation appears to dominate other conventional alternatives in contrast for example to scheff s s projection method richmond s approach focuses on a set of primary points of interest income shares among a more general set of points including the lorenz curve ordinates and optimizes the joint confidence interval lengths on this primary set of points since estimated lorenz curve ordinates are built up from underlying income shares these shares perhaps further supplemented are natural choices for the primary set the method however also provides a joint confidence band that geometrically bounds the set of lorenz curve ordinates and interpolated segments between them the present

international comparisons of welfare and poverty dominance orderings for ten countries inference based stochastic dominance procedures are applied to luxembourg income study data to rank ten western countries in terms of standards of living and poverty first order dominance comparisons ranks more than 50 percent of all pairwise comparisons and second order generalized lorenz dominance adds another 25 percent truncated dominance analysis is used to make inferences about poverty and up to 98 percent of the truncated distributions are ordered the results differ substantially from those obtained when only relative incomes and inequality are considered

inequality in male and female earnings the role of hours and wages the authors decompose annual earnings into hours of work and hourly earnings and analyze male female differences in earnings inequality using canadian data their results indicate that the larger female inequality in earnings is due to a greater inequality in the distribution of hours of work the distributions of wages for men and women are either statistically indistinguishable or more equal for women the authors compare two data points 1988 and 1981 and find the same structure in the gender comparisons also changes between 1988 and 1981 in earnings inequality are generated from movements in the hours distributions copyright 1996 by mit press

testing for poverty dominance an application to canada the paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices this helps provide both normative and statistical confidence in establishing poverty rankings across distributions the tests which can take into account the complex sampling procedures that are typically used by statistical agencies to generate household level surveys are implemented using the canadian survey of labour and income dynamics slid for 1996 1999 and 2002 although the yearly cumulative distribution functions cross at the lower tails of the distributions the more recent years tend to dominate earlier years for a relatively wide range of poverty lines failing to take into account slid s sampling variability as is sometimes done can inflate significantly one s confidence in ranking poverty taking into account slid s complex sampling design as has not been done before can also decrease substantially the range of poverty lines over which a poverty ranking can be inferred

the impact of food stamps on us poverty in the 1980s a marginal dominance analysis the relative effectiveness of the us food stamp program in reducing the incidence and depth of poverty is compared at a number of poverty lines across time the analysis is based upon an extension of dominance methods for ordering poverty recently developed statistical inference procedures and a merged data set that permnits an unusually comprehensive measure of income the comparative effectiveness of the food stamp program in reducing headcount poverty over time is contingent on the poverty line selected however the reduction in poverty gaps is greater in 1990 than in 1982 regardless of the poverty line chosen the sensitivity of the results to the income concept equivalence scale and time period used for measuring income are also considered

consistent testing for stochastic dominance under general sampling schemes we propose a procedure for estimating the critical values of the extended kolmogorov smirnov tests of stochastic dominance of arbitrary order in the general k prospect case we allow for the observations to be serially dependent and for the first time we can accommodate general dependence amongst the prospects which are to be ranked also the prospects may be the residuals from certain conditional models opening the way for conditional ranking we also propose a test of prospect stochastic dominance our method is based on subsampling and we show that the resulting tests are consistent and powerful against some n 1 2 local alternatives we also propose some heuristic methods for selecting subsample size and demonstrate in simulations that they perform reasonably we describe an alternative method for obtaining critical values based on recentring the test statistic and using full sample bootstrap methods we compare the two methods in theory and in practice

testing for marginal changes in income distributions with lorenz and concentration curves asymptotically distribution free statistical tests for comparing absolute and relative lorenz and concentration curves are provided the procedures do not require independent samples and can be used to test for marginal changes in income distributions the tests are illustrated using a large sample of tax returns that have been randomly selected for audit by the internal revenue service the tests reveal the marginal effects of systematic underreporting of income and tax liabilities on the u s income distribution copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

brain waste educated immigrants in the u s labor market the authors investigate the occupational placement of immigrants in the u s labor market using census data they find striking differences among highly educated immigrants from different countries even after they control for individuals age experience and level of education with some exceptions educated immigrants from latin american and eastern european countries are more likely to end up in unskilled jobs than immigrants from asia and industrial countries a large part of the variation can be explained by attributes of the country of origin that influence the quality of human capital such as expenditure on tertiary education and the use of english as a medium of instruction performance is adversely affected by military conflict at home which may weaken institutions that create human capital and lower the threshold quality of immigrants the selection effects of u s immigration policy also play an important role in explaining cross country variation the observed under placement of educated migrants might be alleviated if home and host countries cooperate by sharing information on labor market conditions and work toward the recognition of qualifications

which is a better investment choice in the hong kong residential property market a big or small property the relationship between property size and property investment yield is an interesting issue in the real estate market previous studies usually use the mean variance criterion to compare the return risk profiles of the yields of different property sizes in the united states however this criterion has a few shortcomings this article provides the first attempt to use a stochastic dominance approach to analyse this issue we adopt two powerful stochastic dominance tests to compare the yields of five property size classes in the hong kong residential property market in our study we analyse two possible investment outcomes 1 investors could not rent out their properties and thus they would gain lose from the appreciation depreciation of residential property prices 2 investors could also gain from rental incomes our empirical results provide strong evidence to show that the yields of smaller property classes stochastically dominate the yields of bigger property classes suggesting that buying smal

monetary policy natural resources and federal redistribution can monetary policy shocks induce redistribution across natural resource rich and poor states within a federation we conjecture that resource rich states are capital intensive hence their investment is more responsive to changes in monetary policy consequently contractionary monetary policy shocks e g increases in the interest rate may induce redistribution from resource poor states to resource rich ones via an equalizing federal transfer scheme because investment is reduced more strongly in the latter we test these hypotheses using a panel of u s states covering several decades and find that 1 resource rich states are significantly and persistently more capital intensive 2 contractionary monetary policy shocks induce a relative drop increase in investment federal transfers in resource rich states over the course of four years 3 these patterns are driven by resource induced differences in the capital share in the economy we estimate that a one standard deviation contractionary monetary shock induces within the first year federal redistribution of approximately 2 5 billion from the resource poor to the resource rich states representing about 11 of the total average annual federal transfers received by the latter states

will export rebate policy be effective for co2 emissions reduction in china a ceepa based analysis china has adopted cancellation of export tax rebate policies on many occasions to push ahead energy conservation and emission reduction since 2007 by applying a ceepa china energy environmental policy analysis system model this paper simulates the impacts of the cancellation of export rebates on co2 emissions and socio economic consequences in different scenarios so as to figure out whether it works this paper covers three export rebate scenarios and makes comparisons between the impacts of export rebates on emission reduction effects and that of carbon tax policies the conclusions are 1 the current policy which cancels export rebates for key sectors can cut emissions at huge economic cost yet it is unsustainable 2 the policy which cancels export rebates for key sectors and meanwhile subsidizes sectoral outputs yields double dividends in the short term thus can facilitate emission reduction yet the boost is limited 3 the policy which cancels export rebates and boosts domestic demand helps improving residents welfare in the short term while it may inflict pronounced social and economic impacts in the long run so policy of this kind should be adopted with great caution 4 export rebates generate far more economic costs than carbon tax policies in the long term and don t contribute to optimizing the energy mix as well as the latter in summary canceling export rebates should not be regarded as a priority to encourage emission reduction

norwegian climate policy reforms in the presence of an international quota market abstract this study shows that the second best optimal difference between tax rates on goods that generate greenhouse gas emissions and non polluting goods is equal to the quota price plus a ramsey tax on the quota price when emission quotas are traded between governments and the price elasticity of these goods is identical this tax difference exceeds the second best optimal difference between tax rates on goods that generate a negative externality equivalent to the quota price and non polluting goods model simulations show that a unilateral increase in emission tax to above the international quota price generates a welfare gain for norway model simulations also show that an international tax quota price increase generates a welfare gain loss for norway if norwegian imports of oil become substantial marginal in the long run

alternative models of earnings determination and labor market structures there are three distinct research traditions in the analysis of individual earnings determination human capital or earnings function analyses aggregate wage analyses and labor demand analyses an important and incongruous aspect of each is the treatment of geographical differences in labor markets this paper first investigates the magnitude and character of geographical wage differentials the sizable differences discovered there are then related to the existing and highly simplified models of labor market differences while the two major classes of models compensating differentials and labor demand differ significantly in assumptions and implications it is impossible to distinguish adequately between them there appears to be a clear need for more structural analyses of labor market operations

have air pollutant emissions converged among u s regions evidence from unit root tests previous studies of income distribution have found evidence indicating that incomes across u s regions have converged supporting the prediction of the neoclassical growth model a potential shortcoming in these studies is that only one measure of well being is considered a measure of wealth linked to incomes or production this paper examines whether income convergence was accompanied by air pollutant emission convergence results from unit root tests provide some evidence that indicators of environmental quality have converged across u s regions during the 1929 1994 period

economic and welfare influences of an energy excise tax in jiangsu province of china a computable general equilibrium approach abstract in recent years although china s energy intensity has gradually decreased the total consumption of energy commodities has increased sharply levying an excise tax on energy commodities is one of the keys to control energy consumption this paper constructed a computable general equilibrium model to simulate levying an energy excise tax in jiangsu province which is one of china s strong economic provinces with lower endowments of energy resources the results show that the energy excise tax is beneficial for energy saving while levying energy will cause economic and welfare declines when at a level tax rate of 5 10 and 15 the loss of gdp will reach 0 27 0 66 and 1 13 respectively and the incomes of inhabitants and enterprises alike will decrease when the energy tax revenue used to compensate for the welfare losses suffered by inhabitants or enterprises there is a double dividend effect energy saving and increasing income moreover the simulation indicated that a 5 improvement of energy efficiency brings about a backfire phenomenon with an increase of 142 in energy consumption however when considering the cost of energy efficiency improvements the rebound effect will be significantly decreased policy suggestions are further recommended to help improve the energy policy in regard to reducing energy consumption

regional convergence and national inequality this paper explores the implications of regional income convergence for measures of inequality at the national level in general such convergence occurs as poorer regions overtake more developed ones it is difficult to imagine any realistic scenario in which rising incomes in poorer regions would not have the effect of reducing absolute poverty at the same time it seems reasonable to assume that national inequality would fall as the mean incomes in the various regions converge given these general presumptions the recent economic history of regional convergence between the southern united states and the rest of the nation is quite puzzling over the last twenty five years mean family income in the southern united states has gone from about 80 of the national mean to about 93 at the same time inequality in the south and that in the non south have been changing only slightly when measured by gini coefficients under these circumstances with no serious deterioration in intraregional measures of inequality we would expect to observe a substantial reduction in national inequality as these two broad regions converge in mean incomes nevertheless there has been no significant decline in the national gini coefficient this apparent paradox is in contrast to an earlier period in u s history in which regional convergence occurred while national inequality was falling smolensky 1961 1963 the purpose of this paper is to demonstrate that the relationship between regional convergence and overall inequality is far from obvious in particular we shot that the convergence of mean incomes among regions ceteris paribus is not a sufficient condition for a reduction in common measures of ov erall inequality such as the gini coefficient the ceteris paribas conditions here are that the distribution of population across regions and the relative distribution of income within each region are held constant the proof of this assertion is made in section ii in section iii we demonstrate the relevance of this analysis to the u s case we show that the simple mean convergence of family incomes between the southern united states and the rest of the nation over the last twenty five years should not have been expected to have a direct effect on national inequality the naive link between regional income convergence and national income distribution does not hold up in this important case hence the arguments of section ii are more than analytical curiosa in a situation where the direct effects of income convergence are insufficient to reduce overall inequality there is the possibility that the broader process of regional convergence achieves this result more indirectly regional convergence may involve economic changes that work on intra regional income distributions or the distribution of population across regions in ways favorable to greater national equality in section iv we speculate on such indirect effects from a theoretical point of view we conclude that the direction and extent of such interactions are not obvious

accounting for south non south real wage differentials and for changes in those differentials over time a unified accounting framework for analyzing differences in real wages between the south and non south in 1979 and for changes in south non south wage ratios between 1973 and 1979 is outlined cross section analysis of real wage differentials allows two sources of regional wage variation 1 worker and job characteristics and 2 returns to those characteristics our results suggest that differences in the latter may be as important in accounting for regional wage differentials as the former an interactive specification permits decomposition of changes in regional wage ratios into direct effects of changes in characteristics and indirect effects of region year and region year variations in returns more than half the predicted changes in south non south wage ratios can be accounted for by changing relative returns to characteristics between the south and non south

the theory of reform and indian indirect taxes abstract given a set of value judgements an initial state and a model of the economy one can ask whether some feasible tax change would increase welfare we do this by defining the marginal cost in terms of welfare of raising an extra rupee from the i th good the inverse optimum problem is the calculation of non negative welfare weights on households which imply that the initial state is optimum if no such welfare weights exist then a pareto improvement is possible we illustrate the concepts and results using data from the indian economy for 1979 1980 directions of tax reform for a number of specific social welfare functions and for pareto improvements are presented

once in the door gender tryouts and the initial salaries of managers although women pursue managerial credentials at nearly the same rate as men gender disparities in wages exist because of the shortfall in wages women sustain relative to men at the onset of their careers this article develops a tryout approach to test for the presence of demand side contributions to initial wage inequality while also developing and testing theory on why it may be lessened through internships using detailed data on graduates from an elite management program from 2009 2010 our analyses reveal that internships are associated with the gap in men s and women s initial salaries for men there is no difference in salary offers from employers where an internship occurs versus one where an internship does not occur however women receive higher salaries from employers where an internship first takes place this paper was accepted by olav sorenson organizations

mobility and modality trends in us state personal income we examine the mobility and modality trends in us state per capita personal income and its components during the 1929 1999 period we find strong evidence of convergence for states but that the tendency towards convergence and the associated mobility within the distribution varies during the period and especially for the 1980s our analysis of convergence by income component suggests that transfer income contributes more to the observed convergence than does asset income we also note that distributional mobility need not be accompanied by high rank mobility and find that trends toward convergence in the us have tended to preserve rank ordering cet article cherche a examiner les tendances de mobilite et de modalitequant aux revenus personnels par tete et a ses composants aux etats unis pendant la periode qui va de 1929 a1999 il s avere de fortes preuves d une convergence entre etats qui varie au cours de la periode etudiee et qui va de pair avec une variation de la mobilite associee au sein de

the economic incorporation of immigrants in 18 western societies origin destination and community effects this article examines differences in labor market participation and unemployment between immigrant groups in different countries the authors argue that two macro designs must be combined to provide a more comprehensive perspective on the economic integration of immigrant groups instead of reliance on observations of multiple origin groups in a single destination or a single origin group in multiple destinations multiple origins in multiple destinations are compared suggesting that the economic status of immigrants may be affected by the country from which they come origin effect the country to which they migrate destination effect and the specific relations between origins and destinations community effect from the human capital theory compositional hypotheses are derived which predict that these macro effects can be attributed to the selection of human capital from discrimination theories contextual hypotheses are deduced which maintain that macro effects can be ascribed to in gro

identifying productivity and amenity effects in interurban wage differentials this study focuses on the relative importance of amenity and productivity differences in determining wage differentials across urban areas the approach developed takes advantage of the connection between land and labor market clearing conditions required for locational equilibrium of households and firms data on recent movers are used to estimate equilibrium wages and rents for a sample of metropolitan areas this information is then used to identify amenity and productivity components of wages for each city in the sample using national estimates of the relative share of land in consumption and production differences in productivity and amenities are found to be roughly equal sources of wage variation across the sample

amenities and regional differences in returns to worker characteristics average wages in regions in the united states vary considerably in trying to explain these differences in the average wage across regions a number of studies have found that differences in the returns to characteristics of workers such as years of schooling are as important as differences in the skill composition of the labor force 4 6 10 141 these differences in returns are generally interpreted as reflecting regional differences in demand for worker characteristics coupled with barriers to factor mobility this interpretation is based on the argument that the presence of at least one perfectly mobile factor with perfect information will cause spatial convergence in characteristic prices as that particular factor exploits any spatial price differential 4 p 2161 this paper suggests an alternative to this demand based explanation for regional differences in the structure of wages one based on regional differences in the supply of worker characteristics this explanation does not rely on impediments to the movement of workers or firms and is consistent with an equilibrium view of wages in which regional wage differentials are viewed as compensation for local amenities the theoretical model presented in the following section assumes capital and labor are perfectly mobile with perfect information implying that in equilibrium the utility of workers with similar characteristics is the same in all locations this convergence of utility however does not necessarily imply convergence of characteristic prices equilibrium differences in the returns to a specific worker characteristic can exist if worker characteristics affect an individual s valuation of an area s amenities relative to the individual s demand for land

innis lecture inference on income distributions this paper attempts to provide a synthetic view of varied techniques available for performing inference on income distributions two main approaches can be distinguished one in which the object of interest is some index of income inequality or poverty the other based on notions of stochastic dominance from the statistical point of view many techniques are common to both approaches although of course some are specific to one of them i assume throughout that inference about population quantities is to be based on a sample or samples and formally all randomness is due to that of the sampling process inference can be either asymptotic or bootstrap based in principle the bootstrap is an ideal tool since in this paper i ignore issues of complex sampling schemes and suppose that observations are iid however both bootstrap inference and to a considerably greater extent asymptotic inference can fall foul of difficulties associated with the heavy right hand tails observed with many income distributions i mention some recent attempts to circumvent these difficulties ce memoire tente de fournir une vue synthetique des diverses techniques disponibles pour faire des inferences a partir des repartitions de revenus on peut distinguer deux approches principales l une dans laquelle l objet vise est un indice d inegalite de revenus ou de pauvrete l autre est construite sur des notions de dominance stochastique d un point de vue statistique plusieurs techniques sont utilisees par les deux approches mais certaines techniques sont specifiques a l une ou a l autre approche l auteur postule que l inference a propos de quantites demographiques est fondee sur un echantillon ou des echantillons et que formellement tout le caractere aleatoire est attribuable au processus d echantillonnage l inference est soit asymptotique soit derivee par des technique de bootstrap en principe la seconde facon de proceder est un outil ideal puisque dans ce memoire l auteur ignore les problemes de procedures d echantillonnage complexes et presume que les observations sont idd cependant la seconde facon de proceder et encore plus la premiere peuvent rencontrer des difficultes associees au fait que l on observe des queues de distribution epaisses vers la droite dans plusieurs profils de repartition des revenus l auteur mentionne certains efforts recents pour contourner ces difficultes

trickling down the rising tide new estimates of the link between poverty and the macroeconomy this paper uses pooled time series regressions of regional data to reexamine the link between poverty and the macroeconomy the use of disaggregated data provides additional degrees of freedom and permits the inclusion of controls for demographic changes and increased income inequality the results indicate a stronger relationship between poverty rates and the macroeconomy in the 1980s than that found in prior research and confirm that the dramatic reduction in unemployment during the late 1990s was instrumental in reducing poverty rates the estimated results for the 1990s imply a 0 4 0 9 increase in the poverty rate for each 1 increase in the unemployment rate

effects and mechanism of influence of china s resource tax reform a regional perspective abstract china s resource tax reform beginning with xinjiang as a pilot area in june 2010 marked a new stage in the progression of china s resource tax system based on the 2007 social accounting matrix sam for xinjiang constructed by ourselves this paper takes a regional perspective on china s resource tax reform to quantitatively calculate its degree of influence and qualitatively analyze its mechanism of influence by adopting an energy computable general equilibrium cge model and a sam price model the results show that the main significance of the reform lies in bolstering local government finances rather than energy conservation or carbon reduction this is because revenue will be transferred from resource enterprises and the central government to the local government while simultaneously the low tax rate narrow tax scope and unreasonable price mechanism will combine to prevent the reform from reaching its environmental goals promoting resource price mechanism reform and deepening resource tax reform will be two key elements of china s future energy strategies because resource enterprises will bear the increased burden caused by the reform the degree of sectoral price increases will be limited therefore the fear that resource tax reform will push up inflation is unnecessary and should not be a barrier to reform

the effect of fossil energy and other environmental taxes on profit incentives for change in an open economy evidence from the uk this paper argues that the underlying supply and demand analysis of fossil energy and other environmental taxes needs further elaboration when a country a introduces national fossil energy or environmental taxes and b is open to international trade at given world prices we provide evidence that such conditions are plausible for many sectors in the uk a key implication is that the short run effects of such taxes should not be felt in final good prices since these are determined in world markets but in terms of underlying profitability these changes in underlying profits provide two key incentives for producers to change to more environmentally friendly production techniques and to switch resources to production of less environmentally harmful goods using input output techniques we provide evidence for the uk to show how existing fossil energy and other green taxes have affected underlying profitability the evidence shows quite strong profit incentives to shift resources from a small number of energy intensive industries to others

carbon taxation and market structure a cge analysis for russia abstract russia is one of the world s major sources of carbon based energy as well as one its most intensive users introducing carbon taxes can lead to a reduction in emissions and encourage investment in energy efficiency we investigate the economic effects of carbon taxes on the russian economy under perfect competition and a cournot oligopoly in output markets the main findings are i substituting carbon taxes for labour taxes can yield a strong double dividend in russia however welfare gains strongly depend on the labour supply elasticity and elasticities of substitution between capital labour and energy ii under the assumption of a cournot oligopoly with homogenous products and symmetric firms in the markets for natural gas petroleum and chemical products metals and minerals welfare costs of the environmental tax reform can be higher than under perfect competition this is because introducing carbon taxes leads to a reduction in already sub optimal output thereby exacerbating pre existing distortions arising from imperfect competition iii furthermore increases in energy costs can result in higher mark ups in some markets because of less competition resulting from firms exit

how shifting investment towards low carbon sectors impacts employment three determinants under scrutiny abstract the threat of climate change requires redirecting investment towards low carbon sectors and this shift generates heated debates about its impact on employment many studies exist most of which use cge or input output io models however the economic mechanisms at play remain unclear this paper disentangles the channels of job creation and studies to what extent the results of simpler io models diverge from cge results using stylized models we show that a shift in investment creates jobs in io if it promotes sectors with a higher share of labour in value added lower wages or a lower import rate in cge the first two channels also yield job creation but there is no positive impact of targeting low imports sectors unless these do not export then we undertake a numerical analysis of two policies the installation of solar panels and weatherization in france both policies have a positive effect on employment in both models due to the high share of labour and low wages in these sectors io results provide a good approximation of cge results for solar 14 to 34 and are slightly higher for weatherization 22 to 87 our findings challenge the idea that renewables boost employment by reducing imports but they also suggest that a double dividend can be achieved by encouraging low carbon labour intensive sectors

you can t take it with you immigrant assimilation and the portability of human capital the national origin of an individual s human capital is a crucial determinant of its value education and labor market experience acquired abroad are significantly less valued than human capital obtained domestically this difference can fully explain the earnings disadvantage of immigrants relative to comparable natives in israel variation in the return to foreign schooling across origin countries may reflect differences in its quality and compatibility with the host labor market the return to foreign experience is generally insignificant acquiring additional education following immigration appears to confer a compound benefit by raising the return to education acquired abroad

self selection and the earnings of immigrants this paper analyzes the way in which the earnings of the immigrant population may be expected to differ from the earnings of the native population because of the endogeneity of the decision to migrate the empirical study shows that differences in the u s earnings of immigrants with the same measured skills but from different home countries are attributable to variations in political and economic conditions in the countries of origin at the time of migration excerpt

statistical inference for the measurement of the incidence of taxes and transfers we establish the asymptotic sampling distribution of general functions of quantile based estimators computed from samples that are not necessarily independent the results provide the statistical framework within which to assess the progressivity of taxes and benefits their horizontal inequity and the change in the inequality of income which they cause by the same token these findings characterise the sampling distribution of a number of popular indices of progressivity horizontal inequity and redistribution they can also be used to assess welfare and inequality changes using panel data and to assess poverty when it depends on estimated population quantiles we illustrate these results using micro data on the incidence of taxes and benefits in canada

lorenz dominance and welfare changes in the u s distribution of income 1967 1986 this paper examines income inequality in the untied states over the period 1967 86 using recently developed tests for differences in lorenz curves the authors are able to rank eighteen of nineteen annual comparisons in contrast standard techniques are able to rank only twelve these results suggest that the lorenz dominance principle is more empirically relevant than previously thought the tests reveal a sharp rise in u s inequality between 1978 and 1982 as well as a shift toward greater inequality over the entire period the authors also examine changes in economic welfare using the joint mean lorenz dominance principle copyright 1991 by mit press

the measurement and trend of housing inequality in the united states 1978 85 inequality in housing services for renters owners and all households in the united states is estimated for 1978 and 1985 hedonic techniques are applied to data from the american housing survey to derive values for housing services that include publicly provided as well as subsidized housing we find significant disparities in housing but substantially less inequality than in incomes in 1978 the top decile garnered 19 2 of housing services while the bottom decile received only 5 1 the trend however is towards greater equality in housing with large and statistically significant shifts across all deciles by 1985 the share of the top decile dropped to 16 3 a percentage decrease in share of 15 3 while that of the bottom decile rose to 5 7 a percentage increase of 11 4

information learning and wage rates in low income rural areas in this essay we present evidence that employers in rural areas of developing countries have imperfect information with regard to the productivity of heterogeneous workers in addition to obtaining direct measures of the completeness of employer information we consider the implications of information asymmetries for the structure of casual labor markets we then evaluate the extent to which casual labor markets do in fact exhibit these attributes we find that 1 there is adverse selection out of the time rate labor market 2 employers discriminate statistically given two workers with different observed characteristics but the same actual productivity the worker from the group with the higher average productivity will have a higher wage 3 employers exhibit learning over time the extent of employer ignorance is negatively related to labor market exposure on the part of the workers and 4 calorie consumption affects productivity but is not rewarded in the time rate labor market in concluding we argue that an analysis of wage and employment patterns and the implications of these patterns for human capital investment in rural areas of developing countries that ignored the role of information problems could yield misleading conclusions

sources of inequality in the philippines insights from stochastic dominance tests for richness and poorness new stochastic dominance sd tests of richness and poorness are applied to income and expenditure distributions in the philippines to measure relative welfare levels and investigate sources of inequality from 2000 to 2012 we successfully demonstrate that welfare analyses based on ascending and descending sd principles offer a stronger characterisation of changing levels of welfare in a population than what could be obtained using standard sd approach alone empirically our results show that large improvements in relative welfare over time in the philippines favoured older and female headed households mainly in the urban areas further female headship and more years in education promoted higher welfare within and among the population groups on the other hand the growth of remittance incomes may have caused the greater imbalance in the distributions found in more recent years analysis by age groups meanwhile showed that over time there are increasing concentrations of poorer households among the youngest cohort 30 and under at the same time that there are also increasing concentrations of richer households among the over 60s the combined impact of these factors provides a viable explanation as to why the gap between the rich and the poor has remained high in the philippines for a very long time now

nutrition and nonparticipation in the us food stamp programme microdata from the national food consumption survey are used to test for differences in caloric and protein intake distributions we compare poor households that participate in the us food stamp programme to eligible households that do not participate tests for stochastic dominance provide unambiguous evidence that eligible nonparticipants suffer from relative undernutrition compared to participating households probit analysis is used to identify characteristics of participating and nonparticipating households

accounting for the gap a firm study manipulating organizational accountability and transparency in pay decisions great progress has been made in documenting how employer practices may shape workplace inequality less research attention however has been given to investigating which organizational strategies are effective at addressing gender and racial inequality in labor markets using a unique field study design this article identifies and tests for the first time whether accountability and transparency in pay decisions two popular organizational initiatives discussed among scholars and practitioners may reduce the pay gap by employee gender race and foreign nationality through a longitudinal analysis of a large private company i study the performance based reward decisions concerning almost 9 000 employees before and after high level management adopted a set of organizational procedures introducing accountability and transparency into the company s performance reward system before such procedures were introduced there was an observed gap in the distribution of performance based rewards where women ethnic minorities and non u s born employees received lower monetary rewards compared with u s born white men having the same performance evaluation scores and working in the same job and work unit with the same manager and the same human capital characteristics analyses of the company s employee performance reward data after the adoption of accountability and transparency procedures show a reduction in this pay gap i conclude by discussing the implications of this study for future research about employer strategies targeting workplace inequality and diversity

theories of risk testing investor behaviour on the taiwan stock and stock index futures markets investor behavior towards risk lies at the heart of economic decision making in general and modern investment theory and practice in particular this paper uses both the mean variance mv criterion and stochastic dominance sd procedures to analyze the preferences for four of the most widely studied investor types in the taiwan stock and stock index futures market we find that risk averters concave utility function prefer spot to futures whereas risk seekers convex utility function prefer futures to spot our findings also show that investors with s shaped utility functions prefer spot futures to futures spot when markets move upward downward finally our results imply that investors with reverse s shaped utility functions prefer futures spot to spot futures when markets move upward downward these results are robust with respect to sub periods spot returns including dividends and diversification although we do not check whether risk averters risk seekers and investors with s shaped and reverse sshaped utility functions actually exist in the market we do show that their existence is plausible the implications of our findings on market efficiency and the existence of arbitrage opportunities are also discussed in this study

regional earnings inequality in great britain a decomposition analysis this paper investigates the degree of earnings inequality in great britain over the period 1975 96 using individual based data it finds that the contribution of within group inequality to both earnings inequality cross sectionally and to its trend over time is substantially more important than the contribution of between group inequality thus the primary source of increasing inequality in the overall earnings distribution is increasing inequality within regions and not differences in average earnings between regions a decomposition of the gini coefficient is also adopted to illustrate how regional convergence in average earnings has been accompanied by increasing overall earnings inequality in the uk a partir des donnees aupres des particuliers cet article cherche a examiner l importance de l inegalite des revenus regionaux en grande bretagne de 1975 a 1996 il en resulte que la contribution de l inegalite a l interieur du groupe a l inegalite des revenus par echantillon et sur le temps s avere nett

convergence of the south and non south income distributions 1969 1979 income distribution and inequalities in the southern united states are analyzed and compared with data for the rest of the country the evidence presented in this paper reveals that in the 1970s the souths income distribution either converged or moved significantly closer to the income distribution of the rest of the country the degree of convergence depends on the definition of the recipient unit and to a degree on the particular cost of living index used to deflate southern and non southern incomes the convergence is attributed in part to the labor unionization in the northeast and the resulting relocation of companies to the south data are from the 1970 and 1980 censuses and concern total household income excerpt

equality of opportunity and luck definitions and testable conditions with an application to income in france abstract we offer a model of equality of opportunity that encompasses different conceptions expressed in the public and philosophical debates in addition to circumstances whose effect on outcome should be compensated and effort which represents a legitimate source of inequality we introduce a third factor luck that captures the random factors whose impact on outcome should be even handed for equality of opportunity to be satisfied then we analyze how the various definitions of equality of opportunity can be empirically identified given data limitations and provide testable conditions definitions and conditions resort to standard stochastic dominance tools lastly we develop an empirical analysis of equality of opportunity for income acquisition in france over the period 1979 2000 which reveals that the degree of inequality of opportunity tends to decrease and that the degree of risk of income distributions conditional on social origin appears very similar across all groups of social origins

cumulative gender disadvantage in contract employment women s wages do not grow with experience or tenure as much as men s do many accounts of this cumulative gender disadvantage attribute it to women s underinvestment in firm specific skills yet if that were true this disadvantage would not exist where firm specific skills are not rewarded by the labor market this article investigates this argument in the context of contract employment where demand for firm specificity is minimal contrary to expectations men still receive higher rewards than women over time drawing on quantitative evidence and qualitative fieldwork using job histories of high skill contractors affiliated with a staffing firm the author finds support for two sources of women s disadvantage lower rates of movement across clients on the supply side and unmeasured demand side factors by which similar levels of tenure and client transitions accrue lower rewards to women implications for research on gender stratification and career advancement in nonformalized labor markets are discussed

the impacts of carbon pricing on coastal megacities a cge analysis of singapore abstract pricing carbon is a widely used policy instrument for climate change mitigation quantitative analysis of carbon pricing are mainly conducted at the regional and national level rarely at the city level due to data availability as a representative of coastal megacities that are vulnerable to both climate change and climate policies singapore has announced to impose carbon tax on large direct emitters as a complementary mitigation option to technical measures a city level computable general equilibrium cge model is developed to simulate potential impacts of carbon pricing on the city including paying border carbon adjustment bca on exports or introducing a domestic carbon tax different sector coverages and carbon tax revenue recycling schemes are investigated for domestic carbon tax the simulation results show that a domestic carbon tax is a more cost effective option than paying bca given an identical carbon price at s 10 t co 2 gdp total exports and household consumption would decline less and average abatement cost is much smaller in the carbon tax scenarios compared to the bca scenario in terms of absolute emissions reduction a carbon tax that covers energy manufacturing and land transport sectors would be preferred making emissions around 2 7 lower than 2010 baseline level
