engendering an inclusive low carbon energy transition in japan considering the perspectives and awareness of the energy poor abstract engendering a low carbon energy transition is necessary to limit climate change impacts and temperature rises ideally this transition would be inclusive incorporating all stakeholders however the issue of energy or fuel poverty is a major obstacle to this goal this research investigates energy poverty in japan using a subjective multidimensional energy poverty measure clarifying the linkages between energy poverty and an inclusive just transition in terms of energy system and policy awareness behavior and preferences through the analysis of an original survey we uncover that there is a marked difference between low income and energy poverty households environmental awareness and their subsequent attitude toward the low carbon energy transition currently the energy poor have a negative attitude toward the low carbon energy transition in japan causing a lack of self reported engagement which will not engender an inclusive just transition our findings suggest that if the japanese low carbon energy transition were to be inclusive a further 5 percent of households could participate in the low carbon energy transition through access to solar or renewable energy capital findings identify the need for policies targeted at the energy poor specifically promoting access to solar capital and low carbon technologies in addition to existing policies targeted at low income households

occupational self selection a human capital approach to sex differences in occupational structure a rich and diverse literature exists concerning the distribution of labor incomes one approach namely that of human capital concentrates on lifetime accumulation paths of earnings capacity units human capital individual variations in human capital imply differences in earnings power thereby yielding strong implications concerning earnings distribution within a population despite its explanatory power the human capital model has been widely criticized one criticism centers on its inability to obtain inferences concerning occupational distribution the purpose of this paper is to alleviate at least some such criticism by applying the hedonic price approach so as to embed occupational choice into the human capital framework the significance is that neoclassical economic theory can be used to obtain implications concerning the determinants of occupational structure excerpt

interrupted work careers depreciation and restoration of human capital the quantitative effects and even the existence of a human capital depreciation phenomenon have been a subject of controversy in the recent literature prior work however was largely cross sectional and the longitudinal dimension if any was retrospective using longitudinal panel data on married women in nls we have now established that real wages at reentry are indeed lower than at the point of labor force withdrawal and the decline in wages is greater the longer the interruption another striking finding is a relatively rapid growth in wages after the return to work this rapid growth appears to reflect the restoration or repair of previously eroded human capital the phenomenon of depreciation and restoration is also visible in data for immigrants to the united states however while immigrants eventually catch up with and often surpass natives returnees from the nonmarket do not fully restore their earnings potential

an economic approach to the study of the relationship between housing hazards and health the case of residential fuel poverty in france abstract the impact of housing hazards on health outcomes is becoming a major issue especially given the recent and on going reviews of energy legislation in many european countries a large body of epidemiological literature argues that fuel poverty a frequently debated example of a housing hazard involving low indoor temperatures is associated with heightened health risks by using a large scale nationally representative dataset i seek in this article to delve into this alleged association and uncover a causal relationship between fuel poverty and self assessed health coming from an economics standpoint i used a panel approach based on an instrumental fixed effects model which allow me to analyse causality i used both objective and subjective fuel poverty indicators the results show that there is a significant causal relationship between fuel poverty and self assessed health status the estimated causality is exacerbated when subjective fuel poverty indicators are used the results also show that the negative impact of fuel poverty on health is deferred meaning that fuel poverty takes time to manifest itself in terms of poor health in policy terms this study adds to the debate on investing in housing energy efficiency schemes to reduce fuel poverty and thereby improve health outcomes it also lends support to the argument according to which improving housing conditions to curb fuel poverty is a lever for reducing pubic expenditures on health care

gender differences in training capital and wages this paper constructs an equilibrium job matching model where workers differ in their attachment to the labor force the model predicts that workers with weaker attachment to the labor market will receive lower starting wages and lower post training wages and will be placed in jobs that offer less training and use less capital the implications of the model for gender differences in pay and job assignment are tested with the eopp data set ourfindings suggest that while training intensity during the first three months of employment is similar in positions filled by males and females females are employed in positions that have a shorter duration of on the job training and that use less capital these differences in on the job training and capital in positions filled by men and women as well as a lower market value for women s prior labor market experience account for a substantial part of the gap in wages between males and females

fuel poverty in the uk is there a difference between rural and urban areas abstract fuel poverty is a significant policy issue an argument often made is that rural households are more likely to be fuel poor due to the nature of rural housing stock and the more limited choice of energy sources in rural areas this paper uses panel data to compare the level and dynamics of fuel poverty in rural and urban areas of the uk in addition to descriptive analysis discrete hazard models of fuel poverty exit and re entry are estimated and used to assess the influence of housing and personal characteristics on the time spent in fuel poverty the results indicate that on average the experience of fuel poverty in urban areas is longer with a higher probability of fuel poverty persistence however on average the rural fuel poor appear more vulnerable to energy price increases while living in private accommodation or a flat increases their probability of remaining fuel poor relative to their urban counterparts these results indicate policy effectiveness may differ across rural and urban space however they also emphasise the limits of spatial targeting monitoring the dynamics of fuel poverty is important for ensuring that policy targets are effective and reaching those most in need

objective vs subjective fuel poverty and self assessed health abstract identification of fuel poverty and its impact on individuals is a growing social issue classifying households using subjective measures of fuel poverty yields different results than when objective measures are used moreover there are assessment related difficulties in establishing the effects on health and wellbeing which hinders policy design to tackle this problem in this paper we propose a latent class ordered probit model to control for subjectivity when analysing the influence of fuel poverty on self reported health this methodology is applied to a sample of 25 000 individuals in 11 000 households for the 2011 2014 period in spain where 5 1 million people 11 of the population could not afford to heat their homes to an adequate temperature in 2014 the results show that poor housing conditions low income material deprivation and fuel poverty have a negative impact on health we also find that the effect of objective fuel poverty and other poverty related factors on health are stronger when we control for unobserved heterogeneity among individuals since objective measures alone may not fully capture the adverse effect of fuel poverty on health we advocate policy approaches that combine both objective and subjective measures and its application by policymakers

energy affordability in the eu the risks of metric driven policies abstract this paper provides a pan eu mapping of energy affordability using energy expenditure shares large variations in energy expenditure shares are identified with the shares being significantly higher in new member states than the eu15 first these variations indicate that a single expenditure based pan eu fuel poverty metric is problematic there is a trade off between a metric identifying households in most need within individual member states and one identifying households in a similar position across member states second household level data from the uk france and the republic of ireland are used to simulate the impact of policy interventions involving energy expenditure reductions or income increases on the recorded rate of fuel poverty these simulations highlight that emphasising high level fuel poverty metrics may distort policymakers choices towards improving the picture of fuel poverty rather than maximising welfare improvements robust impact assessments identifying the fuel poverty interventions which deliver the greatest welfare increases for a given cost offer a better means of policy evaluation

empowered examining self disconnection in a postal survey of electricity prepayment meter consumers in new zealand abstract prepayment metering is an electricity payment method often used by low income consumers fuel poverty is an important public health problem in new zealand and is likely to be a particular problem for those using prepayment metering this paper details a nationwide postal survey of consumers undertaken with the support of three major electricity retailers which investigated the advantages and disadvantages of using prepayment metering from a consumer perspective the study surveyed a total pool of 359 randomly selected consumers across the three companies a response rate of 48 the study found that while almost all respondents felt the benefits of using prepayment outweighed the risks of running out of credit or self disconnection 53 of respondents experienced self disconnection in the past year of concern over a third of respondents experiencing self disconnection were without electricity for more than 12 h the frequency of self disconnection was also high with 17 of those disconnecting reporting six or more events in the past year government intervention could reduce the risks and disadvantages involved with using prepayment metering which could then support initiatives aimed at reducing fuel poverty

the gender gap in early career wage growth in the uk the gender pay gap on entry to the labour market is approximately zero but ten years after labour market entry there is a gender wage gap of almost 25 log points this article explores the reason for this gender gap in early career wage growth considering three main hypotheses human capital job shopping and psychological theories human capital factors can explain about 11 log points job shopping about 1 5 log points and the psychological theories up to 4 5 log points depending on the specification but a substantial unexplained gap remains women who have continuous full time employment have had no children and express no desire to have them earn about 8 log points less than equivalent men after 10 years in the labour market

discrimination empirical evidence from the united states the study of discrimination received a major impetus in the 1960 s when increasing social attention focused upon race and gender differentials in market outcomes gary becker s the economics of discrimination 1957 strongly influenced empirical research by providing a definition of wage discrimination and suggesting a specific way in which it might operate during the following years new theories were developed and refined in an attempt to explain why there appears to be continued discrimination in spite of market forces presumably operating against it similarly a large amount of empirical work has been done to determine whether and how much discrimination actually exists and to a lesser extent to test the implications of the various theories even so the hope expressed by becker in the preface of the second edition 1971 that our understanding of discrimination would increase so rapidly that the materials in his book would become obsolete before another decade began has clearly not been fulfilled here we review what has been learned in the intervening years and suggest some fruitful directions for future research 1 the focus of this paper like that of most of the empirical research in this area is on determining the extent of discrimination rather than on testing alternative models of discrimination

fuel poverty and access to electricity comparing households when they differ in needs although sequential stochastic dominance techniques have been used in the literature to make comparisons of income poverty which are robust to the assumptions made about the economies of scale within households the techniques could be applied to a much wider set of issues in this paper these techniques are applied to energy deprivation in guatemala fuel poverty is compared among households with and without access to electricity and it is assessed whether access to electricity for those who do not have access currently would eliminate the observed difference in fuel poverty between the two groups of households

measuring energy poverty in japan 2004 2013 abstract this paper first examines energy or fuel poverty in japan from 2004 to 2013 especially around the time of the 2011 great east japan earthquake geje to analyze the issue the paper employs various poverty and vulnerability measures with the assistance of our unique dataset the results indicate the aggravation of energy poverty among lower income and vulnerable households during the past decade resulting from both the escalation of energy prices and lowering of income the analysis also employs a new decomposition technique and identifies the explanatory factors associated with the increase in energy poverty these results suggest there were major changes in the forces driving the increase in energy poverty before and after the geje after 2011 income alleviates energy poverty in japan with energy prices becoming the main driving factor

measuring energy poverty in greece a comprehensive research in the field of energy poverty is undertaken in this paper in an attempt to highlight the great vulnerability of greek households on energy poverty in the middle of a severe economic crisis till now greek energy policy has been considered insufficient to tackle energy poverty issues as focusing mainly on short term rather than permanent solutions a primary survey has been conducted recording objective data of energy expenses as well as subjective perceptions about housing conditions the findings showed that under the objective expenditure based method 58 of greek households are energy poor among households under the poverty threshold the energy poverty rate exceeds 90 existing and new subjective indicators shed light on other aspects of energy poverty such as the level of thermal comfort at home damp problems detected restriction of other essential needs in order to manage energy payments etc some interesting conclusions are also drawn by exploring the relationship between various indicators it appears that households considered energy poor are not identical when examined by objective and subjective indicators however different indicators complement each other by capturing different aspects of the problem and provide a broader overview of the issue

does france have a fuel poverty trap abstract in this article we focus on fuel poverty dynamics by answering two questions does france have a fuel poverty trap and what are the determinants of staying in or moving out of fuel poverty first we define three states into which individuals may be placed which are as follows the non fuel poverty state the fuel poverty state and the severe fuel poverty state second we use a mover stayer model that divides the population into the following two types of individuals those who remain in the same state during the observation period the stayers and those who move across states the movers this model applies to longitudinal data from mainland france showing that fuel poverty is not an absorbing state indeed a majority of the fuel poor and the severely fuel poor move to another better state therefore we can argue that france has no fuel poverty trap using two econometric models logit and multinomial logit we identify the stability and mobility determinants in different states as expected there is a relationship between income and the likelihood of an individual remaining in a particular state furthermore poor housing implies a greater likelihood of stability in fuel poverty or severe fuel poverty another result is that deterioration in fuel poverty status seems to stem more from difficult financial situations than from bad dwelling conditions

objective and subjective measures of fuel poverty as energy prices continue to rise to reflect the real cost of carbon the numbers of households in fuel poverty is increasing rapidly this paper uses a unique data set to explore one alternative measure of fuel poverty based on whether consumers feel able to afford their energy similar to one introduced by the government a few years ago we explore the links between an expenditure based and our subjective measure of fuel poverty and compare these differences with those between official measures amongst low income households 28 spent more than a tenth of their income on energy in the home and so would be likely to qualify as fuel poor under the most usual definition but only 16 felt unable to afford sufficient energy to keep their homes warm amongst this group who felt they had difficulty in affording sufficient energy less than half were expenditure fuel poor the paper argues that reintroduction of a self reported measure by the government would be a valuable aid to policy development

densification what does it mean for fuel poverty and energy justice an empirical analysis energy is increasingly at the forefront of the global political agenda while there is a longstanding literature relating to fuel poverty and increasingly energy justice there remains little evidence which explores its link with the urban form specifically the purpose of this study is to explore the relationship between the urban consolidation hypothesis and the cultivation of energy justice in australia this study uses data from the household income and labour dynamics in australia hilda survey years 2007 2014 a national probability sample and indefinite life panel the substantive findings of this study demonstrate that for low income and renting households greater urban density corresponds to a higher likelihood of experiencing fuel poverty further for households with a dwelling type described as an apartment two or three storeys there is a separate and quite generalisable indication that this type of dwelling is associated with a lower likelihood of experiencing fuel poverty this study connects the debate regarding urban consolidation and energy consumption to the fuel poverty and energy justice literature alongside this contribution this study also provides policymakers and planners with new evidence to inform remediation policies that are directed at supporting the fuel poor

equilibrium dynamics in a two sector model with taxes in this paper we are concerned with the equilibrium dynamics of a two sector model of endogenous growth with distortionary taxes we show that for certain parameters values and tax schemes every equilibrium orbit except the steady state solution is non interior i e there are times in which one of the sectors is inactive this analysis confirms that in multisector models the set of easily checkable universal conditions that can guarantee the interiority of equilibrium solutions is rather limited journal of economic literature classification numbers d90 e22

on the power of indicators how the choice of fuel poverty indicator affects the identification of the target population in light of the creation of the eu energy poverty observatory epov in january 2018 and the increase in debates on how fuel poverty is measured we propose a critical analysis of fuel poverty indi

subjective versus objective energy burden a look at drivers of different metrics and regional variation of energy poor populations abstract energy poverty is typically assessed using the energy expenditure to income ratio as a metric this metric fails to account though for residents demographics and regional variation in energy consumption in the united states policymakers dealing with energy poverty have faced challenges estimating the needs for energy assistance programs this study seeks to explore regional variations in energy poverty using texas as the region of study this work also explores differences in the populations captured via objective and subjective metrics i e those who are unable to pay their bill and those who state they struggle to do so drawing on survey data this work uses statistical analyses to 1 assess the regional variation of energy poverty defined as a ratio of household income spent on electricity bills 2 determine if there is an association between objective and subjective metrics of energy poverty and 3 identify statistical drivers of objective and subjective energy poverty metrics of respondents 51 of objectively energy burdened individuals indicated they struggled to pay electricity bills and 53 faced great stress due to the electricity bill if policymakers can use metrics that are more accurate in capturing populations facing energy poverty more effective energy poverty policies might be formulated

fuel poverty and well being a consumer theory and stochastic frontier approach abstract evidence and conventional wisdom suggest that general poverty has a negative effect on the well being of individuals however the mechanisms through which this effect occurs are not well understood through economic approach in this paper we analyse the influence of general and fuel poverty as well as the social dimension through peer comparison on the subjective well being of households we develop a novel approach to analyse fuel poverty and well being based on consumer theory individual preferences are modelled using indifference curves and a distance function where the preferences of individuals are affected by their poverty status we use the survey data from the official spanish life condition survey for 2013 which contains over 16 608 observations on household members the results show that both general and fuel poverty influence the reference indifference curve but that individuals also compare themselves with their peers the proposed model also allows us to corroborate how general and fuel poverty affect well being and how effective policies can be designed to improve social welfare

the mediating role of social workers in the implementation of regional policies targeting energy poverty abstract this paper aims to provide a socio political reflection of the role played by social workers in regional policies and of the real needs of households affected by energy poverty the paper also examines the impact of technical specialised training on the ability of social workers to prevent and mitigate conditions of household energy poverty in europe the adoption of a research action participation methodological framework and a training research approach has permitted the opinions of social workers to be collected through surveys and their central role in implementing regional policies to be highlighted the conclusions obtained have made possible the construction of a self diagnosis and data collection tool which increases the ability of social workers to mediate and implement urgent mitigation measures for energy poverty finally regional policies which aim to mitigate household energy poverty are examined from the professional perspective of social workers

ethnic diversity energy poverty and the mediating role of trust evidence from household panel data for australia abstract energy poverty is now a major concern on the public policy agenda in many countries however evidence on the determinants of energy poverty is relatively scant our study contributes to the debate on the determinants of energy poverty by being the first to examine the impact of ethnic diversity on household energy poverty using 12 waves of longitudinal data from the household income and labour dynamics in australia hilda survey we find that in australia ethnic diversity is positively associated with energy poverty our preferred instrumented estimates suggest that a standard deviation increase in ethnic diversity is associated with a 0 103 0 422 standard deviation increase in energy poverty depending on how energy poverty is measured this finding is generally robust to alternative ways of measuring ethnic diversity and energy poverty we identify trust as an important channel through which ethnic diversity operates and point to the need for policies that engender social capital in multicultural societies as a means to harness the benefits of diversity

will you marry me a perspective on the gender gap abstract this paper develops a general equilibrium model of the gender wage gap the difference in earnings is a consequence of a demographic regularity that men tend to marry younger women which may limit women s labor mobility and hence their average earnings however couples are always free not to marry and do so only if it is in each s self interest the intrafamily allocation of resources is determined via non cooperative bargaining this leads to interesting interactions between the game played by husband and wife on the one hand and the competitive environment in which they are immersed on the other the predictions resulting from this model s interplay between locational choice and family bargaining are consistent with the observation that the increasing stress put by women on their careers over the past 30 years has been contemporaneous with reductions in both marriage rates and the gender gap the model provides insight into the consequences of this for the relative welfare of men and women as well as exploring its wider economic implications

discrimination and job uncertainty abstract in this paper i incorporate group behaviour into a model of the labour market and show that discrimination can be the result of competition between coalitions of workers and bosses for jobs if the probability of correctly assessing the productivity of individual workers decreases coalition formation on the basis of recognisable characteristics becomes relatively more rewarding than coalition forming on the basis of productivity the conditions are under which each individual in the endogeneously defined group actively discriminates persons with different recognisable characteristics independent of productivity

outside offers and the gender pay gap empirical evidence from the uk academic labour market using a unique data source on academic economist labour market experiences we explore gender pay and promotions in addition to earnings and productivity measures we have information on outside offers and perceptions of discrimination we find both a gender promotions gap and a within rank gender pay gap a driving factor may be outside offers men receive more outside offers than women of comparable characteristics and gain higher pay increases in response this may arise due to discrimination we find that perceptions of discrimination and also outside job applications correlate with an individual receiving earnings below that expected given their characteristics

the elephant in the energy room establishing the nexus between housing poverty and fuel poverty abstract this paper contributes to the literature on fuel poverty by bringing together the housing cost induced poverty definition and the low income high cost indicator relying on the housing cost induced poverty definition this paper identifies three dimensions of fuel poverty 1 income poverty high cost 2 housing cost induced poverty high cost and 3 fuel cost induced poverty high cost after breaking down the underlying structure of the low income high cost framework this paper proposes an alternative conceptual definition of fuel poverty and puts forward an empirical strategy which can help to identify the households most in need of financial and energy related support an application based on energy cost data in england allows us to identify several policy implications following from our proposed approach

a new measure of italian hidden energy poverty abstract as highlighted by european policymakers and academic research the global economic crisis of 2008 emphasized the energy poverty phenomenon a number of households have had to considerably reduce their energy expenditure but the traditional criteria adopted to calculate energy poverty are not able to measure their number placed in this framework the paper aims to define a new measure of hidden energy poverty suitable to identify which italian households restrain their energy consumption due to their inability to afford energy services a review of the available energy poverty metrics supports the definition of a new indicator that is able to include hidden energy poor consumers considering some key peculiarities such as the poor energy efficiency of buildings the poverty situation low energy consumption and sensitivity to the climate using data from the household budget survey provided by the italian national institute of statistics in 2018 the newly identified indicator supports the assessment of the percentage of italian households in hidden energy poverty and supplies useful insight to policymakers in their effort to support vulnerable consumers

promotion signaling gender and turnover new theory and evidence we extend promotion signaling theory to incorporate gender and across firm mobility within and across job levels evidence from worker firm linked finnish panel data supports our theory for some groups controlling for worker performance inferred from performance related pay within firm promotion probabilities are increasing and wage increases from promotion are decreasing in educational attainment for some educational groups with results stronger for first than for subsequent promotions women have lower promotion probabilities than men and a greater sensitivity of promotion probability to educational attainment across firm promotions are rare but bring wage increases exceeding those for internal promotions and across firm lateral moves

the policy implications of energy poverty indicators abstract the methodologies and indicators that have been proposed in the literature to measure energy poverty are quite diverse some are subjective approaches based on personal or third parties perceptions of affordable warmth at home whereas others calculate objective indicators although these different proposals have already been theoretically compared an empirical comparative analysis that measures in a real case study the practical impact of the theoretical limitations detected for the different indicators was still pending the goal of this paper is thus to contribute to this debate by comparing critically the different approaches used to measure energy poverty in a real case spain in 2015 and to propose a new methodology that might be able to overcome some of the major problems that affect current methods

foreign capital and gender differences in promotions evidence from large brazilian manufacturing firms proquest denotes formulae omitted widespread consensus asserts that occupational segmentation is the chief determinant for gender differences in wages in the brazilian labor market see for example oliveira 2001 although women represent 39 percent of the formal workforce in brazil they amount to only 23 percent of the employees in the sectors that pay relatively higher wages in 2004 as well the predominance of segmentation increases if one restricts attention to managerial positions of which women hold only 14 percent this suggests that limited promotion prospects for women in the brazilian job market may present barriers to their promotion to the upper rungs of the corporate ladder this paper contributes to the literature by examining data from the larg est firms of the brazilian manufacturing industry in particular our goal is to determine whether obstacles to women s ascension exist by tracking the amount of time it takes for a woman to get a promotion to a managerial posi tion the aim is to complement the literature on gender differences in promo tions whose papers mainly focus on computing the promotion rates time to promotion offers a different angle in that samples with a large time span could well present similar likelihoods of promotion for both genders even if the promotion durations are different we construct the duration variable by following from january 1996 to december 2005 every individual who enters the annual report of social information rais database between january 1991 and december 1995 we denote as nonpromoted the individuals who do not obtain a promotion to a managerial position within the sample that is the right censored observations whereas we assign duration zero to the workers who already are in managerial positions in january 1996 accordingly we label as promoted the individuals within our sample who rise to a managerial position that is those with uncensored positive durations investigating dif ferences in promotions is particularly difficult because observationally simi lar male and female workers may display equal promotion rates and durations even in the presence of gender differences for example promotions may differ in quality as far as we know this is the first study to examine gender differences in promotions using microdata from a developing country apart from the obvious interest in finding whether the main stylized facts hold in a latin american country we were also motivated by the quality and availability of the brazilian data in contrast to the many studies that employ data from individual firms see for example cabral ferber and green 1981 gerhart and milkovich 1989 baker gibbs and holmstrom 1994 our study relies on a homogeneous sample of recently hired workers from the brazilian manufac turing industry in the period from 1996 to 2005 our data set is particularly convenient first the data include a wide array of controls for worker and firm characteristics second unlike blau and devaro 2007 we observe multiple workers per establishment at different occupations and hierarchical levels as well as their career paths in terms of occupation and wage a potential limi tation is that our data set does not include any direct measure of on the job productivity and hence we must come up with indirect controls interestingly we find that there are significantly fewer gender differences in the time to promotion within foreign owned firms than within domestic firms in the brazilian manufacturing industry our findings complement to some extent the literature on the differences between multinationals and domestic firms doms and jensen 2006 greene and others 2009 as well as the evidence that gender differences may depend on the nature of the firm 1 we argue that such gender differences are consistent with statistical discrimi nation and self selection we reason as follows suppose there are relatively more women than men who prefer to dedicate more time to their family than to their careers

energy affordability and the benefits system in italy abstract in this paper we discuss a number of ways to define and measure the affordability of energy consumption and we examine the emergence of energy poverty in italy in the period from 1998 to 2011 the paper examines the eligibility criteria for claiming the benefits available to support energy consumption for vulnerable families and it identifies the potential beneficiaries the study assesses the appropriateness of the eligibility criteria by comparing the population targeted by the policy with the population actually facing affordability problems a simulation exercise using the hypothetical scenario most likely to result in energy benefits being made available shows that regardless of the affordability index adopted the provision of state energy benefits has little impact on fuel poverty

male female wage differentials in job ladders much of the male female wage differential exists because men and women are assigned to different jobs within narrow job categories there is no male female differential only a tortured taste theory of discrimination can reconcile these facts we argue that differential movement along job ladders entails comparative advantage so the ability standard for promotion is higher for women this implies that more able women will be passed over in favor of less able men women assumed to have the same ability distribution as men earn less the differential reflects females lower promotion probability not within job discrimination
