the crowding hypothesis and comparable worth although women s pay and occupational distribution have improved during the past few years it is still true that women earn considerably less than men and that their occupational distribution is substantially different because progress has been slow toward equality in the labor market some have called for a comparable worth policy proponents of this approach argue that occupational segregation contributes to the earnings disparity between women and men one theoretical justification for this position is the crowding hypothesis this paper first explains this theory and presents a method used to test its principal hypothesis it then describes an extension of this design for estimating the phenomenon that comparable worth policies address empirical studies conducted in this area are viewed and new findings are presented finally limitations of this analysis are discussed i introduction

is there a glass ceiling in sweden using 1998 data we show that the gender log wage gap in sweden increases throughout the wage distribution and accelerates in the upper tail we interpret this as a strong glass ceiling effect we use quantile regression decompositions to examine whether this pattern can be ascribed primarily to gender differences in labor market characteristics or in the rewards to those characteristics even after extensive controls for gender differences in age education both level and field sector industry and occupation we find that the glass ceiling effect we see in the raw data persists to a considerable extent

measuring and decomposing the gender pay gap a new frontier approach abstract the gender pay gap measures the differences in the wages earned by female workers when compared to male workers accurately measuring the gender pay gap is an important exercise in order to assess how far we are from the ideal of equal pay for work of equal value determining the different sources of the gender pay gap is also very important in order to design appropriate policies for eliminating this gap we develop an enhanced method to measure and decompose the gender pay gap this method is based on the data envelopment analysis dea technique and on the malmquist index mi we use dea and the mi to construct an index reflecting an adjusted measure of the gender pay gap taking into account multiple productive characteristics and multiple types of pay furthermore we propose a decomposition of the gender pay gap into four components same gender pay gap cross gender frontier gap magnitude productive characteristics bias and pay package bias the method is applied to data relative to 15 712 men and 17 175 women working as business and administration associate professionals in the finance and insurance industry in 20 countries the results reveal the existence of a gender pay gap in all countries and that the value of the gap and of its components vary considerably between countries requiring different policies to tackle it

why do women still earn less than men decomposing the dutch gender pay gap 1996 2006 despite major improvements in women s labour market attachment women still earn considerably less than men international research shows that the persistence of the gender pay gap may be due to the fact that although the gap in characteristics between men and women is diminishing changes in the wage structure counteract this change this article will study whether this swimming upstream phenomenon is also playing a role in the rather slow convergence between male and female wages in the netherlands our results indicate that this is not the case most of the changes in the dutch wage structure have been rather favourable to women the lacking convergence in wages has to be explained from the fact that despite the favourable changes the dutch wage structure still contains a considerable implicit gender bias

the structure of the female male wage differential is it who you are what you do or where you work the efficacy of policies to narrow the malelfemale wage differential depends partly on the size of the portion s of the gap targeted previous research finds no between sex wage gap within occupations within employer job cell this is the first study to disentangle segregation by occupation from that based on employer or on job cell in five industries controlling for other forms of segregation occupational segregation produces a gap of 11 percent manufacturing to 26 percent services the wage gaps from establishment and job cell segregation are about 6 percent each since comparable worth acts on the occupation and job cell components it has a potentially large impact

does marriage really make men more productive this paper presents new descriptive evidence regarding marital pay premiums earned by white males longitudinal data indicate that wages rise after marriage and that cross sectional marriage premiums appear to result from a steepening of the earnings profile data from a company personnelfile that includes information on job grades and supervisor performance ratings reveal large marital status pay differences within a narrow range of occupations managers and professionals and environments a single firm married workers tend to be located in higher paying job grades there are very small pay differentials within grades married men receive higher performance ratings than single men as a result they are much more likely to be promoted controlling for rated performance however eliminates the promotion differential sanders korenman is an assistant professor of economics and public affairs at princeton university and is a faculty associate of the office of population research at princeton university and a research affiliate of the national bureau of economic research nber david neumark is an assistant professor of economics at the university of pennsylvania and a research affiliate of the nber korenman wishes to acknowledge the hewlett foundation and the harvard university center for population studies for financial support the authors are grateful to james medofffor making available an extract from the company personnelfile questions regarding data availability should be directed to professor james

residual load renewable surplus generation and storage requirements in germany abstract i examine the effects of increasing amounts of fluctuating renewable energy on residual load which is defined as the difference between actual power demand and the feed in of non dispatchable and inflexible generators i draw on policy relevant scenarios for germany and make use of extensive sensitivity analyses whereas yearly renewable surplus energy is low in most scenarios analyzed peak surplus power can become very high decreasing thermal must run requirements and increasing biomass flexibility substantially reduce surpluses i use an optimization model to determine the storage capacities required for taking up renewable surpluses allowing curtailment of 1 of the yearly feed in of non dispatchable renewables would render storage investments largely obsolete until 2032 under the assumption of a flexible power system further restrictions of curtailment as well as lower system flexibility strongly increase storage requirements by 2050 at least 10 gw of storage are required for surplus integration of which a sizeable share is seasonal storage results suggest that policy makers should work toward avoiding surplus generation in particular by decreasing the must run of thermal generators concerns about surpluses should not be regarded as an obstacle to further renewable expansion the findings are also relevant for other countries that shift toward fluctuating renewables

effects of family background on earnings and returns to schooling evidence from brazil we investigate whether omitted family background variables are responsible for high returns to schooling estimated in brazil returns to schooling fall by about one third when parental schooling is added to wage equations surprisingly the schooling of fathers in law has larger effects on wages than the schooling of fathers on the basis of a model of assortative mating we interpret this as evidence that parental characteristics represent unobservable worker attributes rather than nepotism in the labor market we conclude that the family background bias in returns to schooling is modest and need not imply returns to family connections

understanding the family gap in pay for women with children as the gender gap in pay between women and men has been narrowing the family gap in pay between mothers and nonmothers has been widening one reason may be the institutional structure in the united states which has emphasized equal pay and opportunity policies but not family policies in contrast to other countries that have implemented both the authors now have evidence on the links between one such family policy and women s pay recent research suggests that maternity leave coverage by raising women s retention after childbirth also raises women s levels of work experience job tenure and pay

are those paid more really more productive the case of experience this study uses computerized personnel microdata on the white male managerial and professional employees at a major u s corporation to address the following question can the additional earnings which are associated with more labor market experience at a point in time really be explained by higher productivity at the same point in time our answer to this question based on both cross sectional and longitudinal information is that performance plays a substantially smaller role in explaining cross sectional experience earnings differentials and earnings growth than is claimed by those who have adopted the human capital explanation of the experience earnings profile this response depends critically on our assumption that the performance ratings which supervisors give to their white male managerial and professional subordinates adequately reflect the subordinates relative productivity in the year of assessment we present a great deal of evidence which strongly supports this assumption

the career costs of children this paper analyzes the life cycle career costs associated with child rearing and decomposes their eects into unearned wages as women drop out of the labor market loss of human capital and selection into more child friendly occupations we estimate a dynamic life cycle model of fertility occupational choice and labor supply using detailed survey and administrative data for germany for numerous birth cohorts across dierent regions we use this model to analyze both the male female wage gap as it evolves from labor market entry onward and the eect of pro fertility policies we show that a substantial portion of the gender wage gap is explainable by realized and expected fertility and that the long run eect of policies encouraging fertility are considerably lower than the short run eects typically estimated in the literature

occupational attainment and gender earnings differentials in mexico women earned about 20 8 less than men in mexico in 1987 a difference that increased to 22 0 by 1993 using 1987 93 data from mexico s national urban employment survey the authors study the role of occupational attainment in this wage differential most of the 1987 93 increase in the gender log monthly earnings gap they find can be explained by relative chnges in human capital endowments wage coefficient changes would have slightly reduced the gap all else equal the increasing male female earnings differential was tempered by a substantial decline in gender differences in occupational attainment from 1987 to 1993 most of the male female differences in earnings in both 1987 and 1993 can be explained by differences in rewards to individual endowments rather than gender differences in endowments

is there a glass ceiling over europe exploring the gender pay gap across the wages distribution using harmonised data from the european union household panel we analyse gender pay gaps by sector across the wages distribution for ten countries we find that the mean gender pay gap in the raw data typically hides large variations in the gap across the wages distribution we use quantile regression qr techniques to control for the effects of individual and job characteristics at different points of the distribution and calculate the part of the gap attributable to differing returns between men and women we find that first gender pay gaps are typically bigger at the top of the wage distribution a finding that is consistent with the existence of glass ceilings for some countries gender pay gaps are also bigger at the bottom of the wage distribution a finding that is consistent with sticky floors third the gender pay gap is typically higher at the top than the bottom end of the wage distribution suggesting that glass ceilings are more prevalent than sticky floors and that these prevail in the majority of our countries fourth the gender pay gap differs significantly across the public and the private sector wages distribution for each of our eu countries

the accumulation of human capital during marriage by males married males have significantly higher wage rates than never married widowed or divorced males even when differences in educational attainment experience race and so on are controlled for evidence presented in this paper suggests that most of the unexplained wage differential associated with marital status in earnings regressions results from males accumulating human capital more rapidly when they are married than when those same males are not married the hypothesis that married males earn more than unmarried males because marriage facilitates the financing of human capital accumulation is supported by this and other evidence

household specialization and the male marriage wage premium empirical research has consistently shown that married men have substantially higher wages on average than otherwise similar unmarried men one commonly cited hypothesis to explain this pattern is that marriage allows one spouse to specialize in market production and the other to specialize in home production enabling the former usually the husband to acquire more market specific human capital and ultimately earn higher wages the authors test this hypothesis using panel data from the national survey of families and households the data reveal that married men spent virtually the same amount of time on home production as did single men albeit on different types of housework estimates from a fixed effects wage equation indicate that the male marriage wage premium is not substantially affected by controls for home production activities household specialization the authors conclude does not appear to have been responsible for the marriage premium in this sample

against the wind bargaining recentralisation and wage inequality in norway 1987 91 in the late 1980s norway s labour market experienced similar supply and demand shifts for skills to other countries but unlike other oecd nations norway s wage setting system became more centralised the pay distribution in norway became more compressed at the bottom from 1987 to 1991 while low wage workers in other countries lost ground relatively using norwegian microdata for 1987 and 1991 i found that changing labour market prices helped cause this wage compression further the less educated had declining relative overall employment but increasing relative public sector employment both possible labour market responses to the wage compression

market specific effects of rail deregulation since partial deregulation of the railroad industry in 1980 real rail rates have fallen yet previous studies are inconclusive in identifying deregulation as the reason for lower rates in this paper the author develops a model that tests a variety of deregulation effects on the rates charged for transporting thirty four different commodities the results suggest that deregulation has significantly affected almost all commodities and that the effects vary by commodity and through time initially deregulation increased rates for some commodities had no effect on others and decreased rates on still others however by 1988 deregulation lowered rates significantly for almost all commodities copyright 1994 by blackwell publishing ltd

family background and the estimated return to schooling earnings regressions for married and cohabiting swedish males in 1993 indicate that controlling for family background reduces the measured return to education by about 9 percent net of measurement error bias the swedish evidence is generally consistent with the hypothesis that family background effects are primarily a result of an efficient marital sorting

a cross national comparison of the gender gap in income this article examines national labor market samples from two dualist countries the united states and canada and two corporatist countries norway and sweden labor market location is less powerful in predicting income in norway and sweden where they have more inclusive employment policies in sweden though the labor market variables are more important in explaining the income gap family effects marital status and number of children are weak everywhere but especially in scandinavia nevertheless because it is encouraged by policies designed to integrate employment and family part time paid work has a major effect on the gender gap in income in norway and sweden women however pay more of a penalty than men for part time employment in north america

unequal pay or unequal employment a cross country analysis of gender gaps we analyze gender wage gaps correcting for sample selection induced by nonemployment we recover wages for the nonemployed using alternative imputation techniques simply requiring assumptions on the position of imputed wages with respect to the median we obtain higher median wage gaps on imputed rather than actual wage distributions for several oecd countries however this difference is small in the united states the united kingdom and most central and northern eu countries and becomes sizable in southern eu countries where gender employment gaps are high selection correction explains nearly half of the observed negative correlation between wage and employment gaps

the development of the neoclassical tradition in labor economics this essay on labor economics examines neoclassical theory s rise to ascendancy following the second world war with a secondary focus on the relative decline but continued influence of institutionalist economic theory the authors describe the evolution of institutional and neoclassical theory from the late nineteenth to mid twentieth centuries examine some early intellectual debates between the two camps briefly describe the work of neoclassical labor economics pioneers and look at major developments over the past 30 years they argue that neoclassical economists increasing intellectual breadth and influence in public policy have led them to pay closer attention to issues that have long been of concern to institutionalists and neoinstitutionalists

language and the estimates of the gender wage gap in this paper we link the estimates of the gender wage gap with the gender sensitivity of the language spoken in a given country we find that nations with more gender neutral languages tend to be characterized by lower estimates of gwg the results are robust to a number of sensitivity checks

occupational segregation and the gender wage gap in a dynamic east asian economy labor markets in the east asian miracle economies have undergone profound changes in recent decades as their comparative advantage in low wage labor diminished and jobs shifted toward higher skill manufacturing and services this study uses an occupational decomposition technique to examine how such shifts in east asia s occupational structures have affected trends in their gender wage gaps the wage gap is decomposed into across occupation and within occupation factors that are each further separated into wage and employment components results based on a comprehensive labor force data set for taiwan show that within occupation pay discrepancies account for the bulk of gender wage inequity

renewable electric energy integration quantifying the value of design of markets for international transmission capacity abstract integrating large quantities of variable renewable electricity generation remains a political and operational challenge one of the main obstacles in europe to installing at least 200 gws of power from variable renewable sources is how to deal with the insufficient network capacity and the congestion that will result from new flow patterns we model the current methodology for controlling congestion at international borders and compare its results under varying penetrations of wind power with models that simulate an integrated european network using nodal localised marginal pricing the nodal pricing simulations illustrate that congestion and price patterns vary considerably between wind scenarios and within countries and that a nodal price regime could make better use of existing network capacity introducing substantial operational cost savings and reducing marginal power prices in the majority of european countries

trends in the gender earnings differential in urban china 1988 2004 this paper analyzes changes in the gender earnings gap in urban china over the period 1988 2004 using urban household survey data the mean female male earnings ratio declined from 86 3 to 76 2

on the economics of electrical storage for variable renewable energy sources abstract the use of renewable energy sources is a major strategy to mitigate climate change yet sinn 2017 argues that excessive electrical storage requirements limit the further expansion of variable wind and solar energy we question and alter strong implicit assumptions of sinn s approach and find that storage needs are considerably lower up to two orders of magnitude first we move away from corner solutions by allowing for combinations of storage and renewable curtailment second we specify a parsimonious optimization model that explicitly considers an economic efficiency perspective we conclude that electrical storage is unlikely to limit the transition to renewable energy

trends in earnings differentials by gender 1971 1981 this paper clarifies trends in relative earnings by sex over the decade 1971 1981 and decomposes these trends to determine which factors contributed to a decline and which to an increase our analyses are based upon data from the annual demographic files of the current population survey for 1972 and 1982 this study is unique in that it estimates earnings functions in each year which are corrected for selectivity bias it is found that such a correction markedly raises the progress of white women relative to men among blacks the impact of the selectivity bias correction was to substantially lower the relative earnings increase of women however the coefficients on the selectivity variable were not significant the findings suggest declining sex role specialization and discrimination as conventionally measured over the decade on the other hand contrary to expectations the total effect of variables reflecting the sex composition of the individuals occupation worked to widen the sex differential over the period the sex differential was also adversely affected by a decline in the relative return to education especially for whites authors modified

competing land uses and fossil fuel and optimal energy conversion rates during the transition toward a green economy under a pollution stock constraint abstract we study the transition to a carbon free economy in a model with a polluting non renewable resource and a clean renewable resource transforming primary energy into ready to use energy services is costly and more efficient energy transformation rates are more costly to achieve renewable energy competes with food production for land and the food productivity of land can be improved at some cost to avoid catastrophic climate damages the pollution stock is mandated to stay below a given cap when the economy is not constrained by the cap the efficiency of energy transformation increases steadily until the transition toward the ultimate green economy when renewable energy is exploited its land use rises at the expense of food production food productivity increases together with the land rent but food production drops the food and energy prices increase and renewables substitute for non renewable energy during the constrained phase the economy follows a constant path of prices quantities efficiency rates food productivity and land rent a phenomenon we call the ceiling efficiency paradox

some inconvenient theses there is a strong tendency for energy technologists and policy analysts to believe that energy demand can be met and associated problems including climate change can be solved and to focus attention on finding the best technologies to achieve these goals they tend not to be comfortable with any suggestion that there might be insurmountable limits and insoluble problems or that the problems they are working on require social solutions rather than technical solutions various contributions to this special edition provide illustrations this paper explores some challenges to the dominant promethian world view these include a consideration of the magnitude of the energy and other problems the possibility that renewable energy cannot solve them the significance of energy and of declining eroi for economic growth and the possible effects of rising resource input costs and unstable capital markets for energy investment finally the ultimate heresy is considered the possibility that access to abundant energy would not be good for us in summary it is suggested that coercive limits to growth are being encountered and that the resulting problems cannot be solved by action on the supply side but will require a radical rethinking of social goals systems and values

unions and nonunion wage dispersion previous research has found that union standard rate policies lower the dispersion of union wages and that unions indirectly raise nonunion wage levels as firms weigh the probability of unionizing and wage costs these two findings imply that unions lower the dispersion of nonunion wages since for a given payroll a nonunion firm can achieve the greatest reduction in the probability of unionism by giving raises to those who would benefit most from a union this hypothesis is confirmed on current population survey data taking into account the endogeneity of unionism ceteris paribus nonunion wage dispersion is lower in more highly unionized industries copyright 1987 by mit press

marital status child rearing and earnings differentials in the graduate labour market differential the importance of family role specialisation for the measurement of the residual earnings differential is examined within a sample selection model of participation and earnings the earnings differential between men and women may be divided into that explained by different characteristics and attributes and that due to residual factors one element of this residual may be discrimination although other factors may be incorporated in the unexplained component the residual also incorporates the effects on earnings associated with the production of home goods see polachek ig75 a b these will occur

gender wage inequality during sri lanka s post reform growth a distributional analysis abstract this paper investigates gender wage inequality in sri lanka during 1992 2014 a period of robust economic growth following pro market reforms the gap in mean wages between men and women decreased steadily over this period unconditional quantile regression reveals the decline in gender wage inequality was driven by the upper half of the distribution and was due to improvements in women s observable human capital yet the pay structure became more unequal indicating widening gender gaps in the returns to labor market characteristics and in unobservable determinants of wages the gender gap in pay structure widened disproportionately in the lower half of the distribution coinciding with falling absolute and relative returns to women in manufacturing industries and production occupations facing greater international competition the study also demonstrates selection bias underestimates the gender wage gap and overestimates the gains in equality over time factors that hinder gender equality in the labor market are discussed along with policy implications

why the gender gap in wages narrowed in the 1980s since 1976 the gender gap in wages on average declined by about 1 per year this article focuses on identifying the factors underlying this trend three data sets are analyzed the current population survey the panel study of income dynamics and the national longitudinal survey we find that convergence in measurable work related characteristics schooling and work experience explains one third to one half the narrowing the remainder is attributable to a relative increase in women s returns to experience as well as to declining wages in blue collar work and other factors

on the economics of renewable energy sources abstract with the global expansion of renewable energy re technologies the provision of optimal re policy packages becomes an important task we review pivotal aspects regarding the economics of renewables that are relevant to the design of an optimal re policy many of which are to date unresolved we do so from three interrelated perspectives that a meaningful public policy framework for inquiry must take into account first we explore different social objectives justifying the deployment of re technologies and review model based estimates of the economic potential of re technologies i e their socially optimal deployment level second we address pivotal market failures that arise in the course of implementing the economic potential of re sources in decentralized markets third we discuss multiple policy instruments curing these market failures our framework reveals the requirements for an assessment of the relevant options for real world decision makers in the field of re policies this review makes it clear that there are remaining white areas on the knowledge map concerning consistent and socially optimal re policies

is there a wage bonus from drinking unobserved heterogeneity examined while the result that drinkers earn more than abstainers has been remarkably persistent only one paper in the literature on drinking and earnings has been written where individual fixed effects are included this study improves the current literature by utilizing a much longer panel and focuses on the low end of drinking while controlling for unobserved heterogeneity with the inclusion of individual specific effects it is found that while ols specifications yield a positive significant coefficient on current drinking even when a rich set of covariates is controlled for including individual fixed effects renders the coefficient statistically insignificant

wage structure and gender earnings differentials an international comparison using microdata to analyse the gender pay gap in ten industrialized nations we focus on the role of wage structure the prices of labour market skills in influencing the gender gap we find wage structure enormously important in explaining why the us gender gap is higher than that in most other countries we conclude that the us gap would be similar to that in sweden and australia the countries with the smallest gaps if the united states had their levels of wage inequality this finding reflects the larger penalty in the united states for those with low skill levels or employed in low wage sectors 650 o 75 the united states was amoung the countries with the largest differ entials oecd ilo usbls this paper uses microdata to analyse inter national differences in the gender pay gap among a sample of ten industrialized nations we focus particularly on explaining the surprisingly low ranking of the united states in comparison with other industrialized countries an advan tage of an international perspective is that countries vary considerably with respect to governmental policies women s relative labour market qualifications and wage setting institutions such variability allows one to infer reasons for differences in the pay gap and by implication the impact of alternative govern ment policies empirical research on gender pay gaps has traditionally focused on the role of gender differences in qualifications and on differences in the treatment of otherwise equally qualified male and female workers i e labour market dis crimination analyses of trends over time in the gender differential within countries as well as inter country comparisons of gender earnings ratios have tended to emphasize these types of gender specific factors an innovative feature of our study is to focus on the role of wage structure as an additional factor influencing the gender gap to analyse the impact of wage structure we adapt a framework developed by juhn et al 1991 to analyse trends over time in race differentials in the united states our findings suggest that labour market institutions that affect overall wage inequality have an extremely impor tant effect on the gender earnings gap wage structure describes the array of prices set for various labour market skills measured and unmeasured and rents received for employment in par

the effects of competition and equal treatment laws on gender wage differentials discrimination if it is inefficient can be eliminated by competition in most countries it is also forbidden by law this paper evaluates the influence of economic and legal factors on the portion of male female wage differentials that is not explained by other worker characteristics and may be due to discrimination we use a new international data set of suitable gender wage gap measures constructed from the results of existing studies meta analysis of the data shows that increased competition and adoption of international conventions concerning equal treatment laws both reduce gender wage gaps while legislation that prevents women from performing strenuous or dangerous jobs tends to increase it doris weichselbaumer and rudolf winter ebmer

examining equality between public and private sector wage distributions i introduction institutional political and economic factors all contribute to the determination of public sector wages for example the public sector is almost the only place in many advanced economies where unions continue to have a significant presence and an influential voice in setting wages and conditions of work political factors such as desiring to be a good employer may also influence the public sector wage structure as a good employer governments may offer low skilled workers higher rates of pay than they might get in the private sector on the other hand the public sector may be adverse to paying very skilled workers high rates of pay if the public does not like to see public sector workers earning too much economic factors such as spending and tax receipt limits can also affect the wage structure in the public sector all of these factors could make the public sector labor market be less efficient than that of the private sector from an economic perspective if government workers are paid more than private sector workers ceteris paribus then taxes are being wasted if private sector workers are paid more than government workers governments cannot recruit and retain appropriately skilled and productive workers to make the wage structures comparable many countries use surveys to ascertain the prevailing earnings levels for jobs in the private sector that are similar to public sector jobs however as fogel and lewin 1974 and gregory 1990 point out these survey methods are fraught with biases that may affect comparability of wages indeed there is little empirical evidence that wages between the two sectors are equal bender 1998 and gregory and borland 1999 survey the current literature on public private wage differentials and report that most studies find that central governments pay more on average compared to the private sector even after controlling for differences in the productive characteristics of workers furthermore as elliott et al 1999 find comparability in pay is currently important in the debates over public sector pay reform particularly in europe the institutional and political factors outlined above are waning in importance and economic considerations are seemingly coming to the fore because of perceptions of the overpayment of public sector workers and the desire to cut government wage bills politicians in these countries are devising policies to align average rates of pay by slowing the relative rate of public sector wage growth the policies should be different however if wage distributions are not the same indeed there is some evidence that the distributions differ as found in the double imbalance concept articulated by schager 1993 katz and krueger 1993 and elliott and duffus 1996 this imbalance is characterized by public sector workers at the lower end of the occupational hierarchy receiving the largest wage premia and workers at the upper end earning less than their private sector counterparts if the distributions are incomparable ceteris paribus mandating equal average rates of pay growth will not ensure comparability policies aimed at realigning wage structures at the ends of the distribution should then be followed to promote comparability this article compares public and private sector wage distributions and examines the extent to which focusing exclusively on differences in mean wages obscures the true nature of the wage relativities data from the british social change and economic life initiative sceli are employed to investigate comparability this data set is well suited for a comparability study given the range of personal and job characteristics that control for differences in public and private sector jobs moreover the data were collected in 1986 before substantial reform of public sector pay in the united kingdom reviewed in bender and elliott 1999 this offers a test to see if the reform policies were appropriate to promote wage comparability

marital status and earnings of young men a model with endogenous selection it is a matter of course in applied labor economics to presume that marital status is a predetermined contributor to earnings among young males we find no evidence to support that proposition we estimate a model of earnings determination that permits endogenous selection of marital status our estimates are based on a sample of young employed males from the michigan panel survey of income dynamics they indicate that marital status viewed in this manner does not significantly shift the mean earnings profile our sensitivity tests indicate that this conclusion is robust with respect to a variety of alternative specifications excerpt

theories of regulation and the deregulation movement we started this paper with what seemed a paradox no sooner had the various special interest theories of regulation achieved a degree of acceptance than regulatory reforms were instituted in many industries consistent with the public interest on the face of it this appeared to give reason to doubt the validity of the special interest theories

buffering volatility a study on the limits of germany s energy revolution squaring hourly demand and wind solar production data for germany and a number of neighbouring countries with the results of the eu s estorage project this paper studies the limits of germany s energy revolution in view of the volatility of wind and solar power in addition to pumped storage it considers double structure buffering demand management norwegian hydro dam buffering and international diversification via grid expansion if germany operated in autarchy and tried to handle the volatility of wind solar production without using stores while replacing all nuclear and fossil fuel in power production on average 61 and at the margin 94 of wind solar production would have to be wasted given the current level of other renewables to avoid any waste the wind solar market share in an autarchic solution must not be expanded to more than 30 by using norway s hydro plants the share could be expanded to 36 if norway were to build all the pumped storage plants the estorage study deems feasible germany s wind solar market share could be expanded by another 24 percentage points to about 60 which corresponds to 48 of the combined german and norwegian markets additionally expanding the market to switzerland austria and denmark and building the maximal number of pumped stores would increase the combined wind solar market share for all five countries to nearly 50 c 2017 the author s published by elsevier b v

the impact of employer provided health insurance on dynamic employment transitions we estimate the impact of employer provided health insurance ephi on the job mobility of males over time using a dynamic empirical model that accounts for unobserved heterogeneity previous studies of job lock reach different conclusions about possible distortions in labor mobility stemming from an employment based health insurance system a few authors find no evidence of job lock although most find reductions in the mobility of insured workers of between 20 and 40 percent we use data from the national longitudinal survey of youth which includes variables describing the health insurance an individual holds as well as whether he is offered insurance by his employer this additional information allows us to model the latent individual characteristics that are correlated with the offer of ephi the acceptance of ephi and employment transitions our results provide an estimate of job lock unbiased through correlation with positive job characteristics and individual specific turnover propensity we find no evidence of job lock among married males and produce small estimates of job lock among unmarried males of between 10 and 15 percent

railroad deregulation pricing reforms shipper responses and the effects on labor the staggers rail act of 1980 relaxed restrictions on pricing and eased abandonment procedures in the railroad industry although the act made virtually no reference to labor its impact on labor has been dramatic the long term contraction of industry employment accelerated quite sharply after 1980 wages increased until 1985 then declined substantially the authors whose empirical analysis uses data on aggregate rail employment for the years 1963 90 current population survey data for 1973 88 and evidence from collective bargaining agreements for 1971 90 argue that pricing adjustments under the staggers act led to changes in shipper behavior which in turn allowed for large declines in the derived demand for rail labor despite increasing output and the observed pattern of wage change followed from the realization of the act s eventual effects on employment

balancing power and variable renewables three links abstract balancing power is used to quickly restore the supply demand balance in power systems the need for this tends to be increased by the use of variable renewable energy sources vre such as wind and solar power this paper reviews three channels through which vre and balancing systems interact the impact of vre forecast errors on balancing reserve requirements the supply of balancing services by vre generators and the incentives to improve forecasting provided by imbalance charges the paper reviews the literature provides stylized facts from german market data and suggests policy options surprisingly while german wind and solar capacity has tripled since 2008 balancing reserves have been reduced by 15 and costs by 50

equalizing discrimination and cartel pricing in transport rate regulation there are two possible outcomes of transport regulation 1 maintaining a carrier cartel and 2 imposing equalizing discrimination against advantaged and in favor of disadvantaged shippers both functions have required a complex rate structure to enforce the respective forms of price discrimination using a sample of freight bills from motor carriers and railroads this paper demonstrates that the principal result of motor carrier regulation has been to maintain a cartel of truckers while railroad regulation has thwarted the wishes of the railroad cartel by imposing equalizing discrimination on weak and strong shippers motor carrier rates respond in an economically rational manner to costs and shipper bargaining power rail rates are either unresponsive or perversely responsive to the same factors deregulation should have divergent effects in the two industries

equal pay for equal work evidence from sweden and a comparison with norway and the u s using a new data set covering most privately employed workers in sweden we compare gender wage differences to those previously reported for norway and the u s the central finding is that the wage gap is small when comparing men and women working in the same type of occupation for the same employer segregation of men and women by occupation accounts for more of the gap in sweden than in the other two countries in all three countries we find that segregation by occupation explains more than segregation by establishment and that institutional changes over the past two decades aimed at improving the status of women had little effect on the gender wage gap jel classification j16 j71
