can falling supply explain the rising return to college for younger men a cohort based analysis although the college high school wage gap for younger u s men has doubled over the past 30 years the gap for older men has remained nearly constant in the united kingdom and canada the college high school wage gap also increased for younger relative to older men using a model with imperfect substitution between similarly educated workers in different age groups we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups the driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries

the empirical content of the roy model this paper clarifies and extends the classical roy model of self selection and earnings inequality the original roy model based on the assumption that log skills are normally distributed is shown to imply that pursuit of comparative advantage in a free market reduces earnings inequality compared to the earnings distribution that would result if workers were randomly assigned to sectors aggregate log earnings are right skewed even if one sectoral distribution is left skewed most major implications of the log normal roy model survive if differences in skills are log concave however few implications of the model survive if skills are generated from more general distributions we consider the identifiability of the roy model from data on earnings distributions the normal theory version is identifiable without regressors or exclusion restrictions sectoral distributions can be identified knowing only the aggregate earnings distribution for general skill distributions the model is not identified and has no empirical content with sufficient price variation the model can be identified from multimarket data cross sectional variation in regressors can substitute for price variation in restoring empirical content to the roy model

assessing the equalizing force of mobility using short panels france 1990 2000 in this paper we document whether and how much the equalizing force of earnings mobility has changed in france in the 1990 s for this purpose we use a representative three year panel the french labour force survey we develop a model of earnings dynamics that combines a flexible specification of marginal earnings distributions to fit the large cross sectional dimension of the data with a tight parametric representation of the dynamics adapted to the short time series dimension log earnings are modelled as the sum of a deterministic component an individual fixed effect and a transitory component which is assumed first order markov the transition probability of the transitory component is modelled as a one parameter plackett copula we estimate this model using a sequential expectation maximization algorithm we exploit the estimated model to study employment earnings inequality in france over the 1990 2002 period we show that in phase with business cycle fluctuations a recession in 1993 and two peaks in 1990 and 2000 earnings mobility decreases when cross section inequality and unemployment risk increase we simulate individual earnings trajectories and compute present values of lifetime earnings for various horizons inequality presents a hump shaped evolution over the period with a 9 increase between 1990 and 1995 and a decrease afterwards accounting for unemployment yields an increase of 11 moreover this increase is persistent as it translates into a 12 increase in the variance of log present values the ratio of inequality in present values to inequality in one year earnings a natural measure of immobility or of the persistence of inequality remains remarkably constant over the business cycle

selection investment and women s relative wages over time in theory growing wage inequality within gender should cause women to invest more in their market productivity and should differentially pull able women into the workforce our paper uses heckman s two step estimator and identification at infinity on repeated current population survey cross sections to calculate relative wage series for women since 1970 that hold constant the composition of skills we find that selection into the female full time full year workforce shifted from negative in the 1970s to positive in the 1990s and that the majority of the apparent narrowing of the gender wage gap reflects changes in female workforce composition we find the same types of composition changes by measuring husbands wages and national longitudinal survey iq data as proxies for unobserved skills our findings help to explain why growing wage equality between genders coincided with growing inequality within gender

nonparametric estimation of sample selection models sample selection models provide an important way of accounting for economic decisions that combine discrete and continuous choices and of correcting for nonrandom sampling nonparametric estimators for these models are developed in this paper these can be used for estimating shapes and important economic quantities as in standard nonparametnc regression endogeneity of regressors of interest is allowed for series estimators for these models are developed which are useful for imposing additivity restnctions that arise from selection corrections convergence rates and asymptotic normality results are derived an application to returns to schooling among australian young females is given

introduction imperfect information and rural credit markets puzzles and policy perspectives rural credit markets have been at the center of policy intervention in developing countries over the past forty years many governments supported by multilateral and bilateral aid agencies have devoted considerable resources to supplying cheap credit to farmers in a myriad of institutional settings the results of many of these interventions have been disappointing and one explanation for this must be that they were based on an inadequate understanding of the workings of rural credit markets the articles in this symposium issue are devoted to empirical and theoretical investigations of rural credit markets in the framework of the imperfect information paradigm the authors show how this framework is useful not only in explaining puzzling features of these markets but also in providing a policy perspective to assess the successes and failures of specific interventions

an empirical investigation of rationing constraints in rural credit markets in india abstract the literature on rural credit markets has generally assumed that households are rationed in their access to subsidized formal credit the validity of this assumption depends on the level of effective demand for formal credit in turn a function of the demand for credit and its availability from informal sources this paper estimates the demand and the sector specific costs of credit and hence the extent of formal sector rationing through an analysis of household participation in both the formal and the informal credit sectors the results show that the extent of rationing is considerably less than what is conventionally assumed

counterfactual decomposition of changes in wage distributions using quantile regression we propose a method to decompose the changes in the wage distribution over a period of time in several factors contributing to those changes the method is based on the estimation of marginal wage distributions consistent with a conditional distribution estimated by quantile regression as well as with any hypothesized distribution for the covariates comparing the marginal distributions implied by different distributions for the covariates one is then able to perform counterfactual exercises the proposed methodology enables the identification of the sources of the increased wage inequality observed in most countries specifically it decomposes the changes in the wage distribution over a period of time into several factors contributing to those changes namely by discriminating between changes in the characteristics of the working population and changes in the returns to these characteristics we apply this methodology to portuguese data for the period 1986 1995 and find that the observed increase in educational levels contributed decisively towards greater wage inequality copyright 2005 john wiley sons ltd

quantile selection models with an application to understanding changes in wage inequality we propose a method to correct for sample selection in quantile regression models selection is modeled via the cumulative distribution function or copula of the percentile error in the outcome equation and the error in the participation decision copula parameters are estimated by minimizing a method of moments criterion given these parameter estimates the percentile levels of the outcome are readjusted to correct for selection and quantile parameters are estimated by minimizing a rotated check function we apply the method to correct wage percentiles for selection into employment using data for the uk for the period 1978 2000 we also extend the method to account for the presence of equilibrium effects when performing counterfactual exercises

identifying barriers in the diffusion of renewable energy sources abstract rapid diffusion of renewable energy sources res in the electricity power sector is crucial if the eu wants to fulfill its 2050 co2 reduction commitments for this reason identifying and alleviating all barriers that hinder the development of res is necessary to the successful deployment of these technologies this paper discusses the main barriers in the diffusion of wind and photovoltaic pv solar power in the greek electricity sector by drawing on the literature of technological innovation systems and system functions furthermore we provide an explanation of the different diffusion rates between the two technologies inadequate financial resources low grid capacity delays in the issuance of building permits opposition from local communities to the construction of wind farms and the lack of a stable institutional framework are among the most important barriers that inhibit the diffusion of the wind and pv solar power the nature of the barriers identified in this study calls for policy intervention

formal microlending and adverse or nonexistent selection a case study of shrimp farmers in bangladesh microcredit schemes have become a popular means of improving smallholders access to credit and making long term investment possible however it remains to be explored whether the current microcre

trouble in the tails what we know about earnings nonresponse thirty years after lillard smith and welch earnings nonresponse in household surveys is widespread yet there is limited knowledge of how nonresponse biases earnings measures we examine the consequences of nonresponse on earnings gaps and

credit as insurance in agrarian economies abstract this paper examines consumption credit as an insurance mechanism in agrarian economies it explains the more rapid adoption of new technology in the green revolution by large farmers who had greater access to consumption credit the paper also demonstrates how the emergence and expansion of consumption credit markets by mitigating the need for hoarding in order to meet consumption contingencies enhances growth by encouraging investment

changes in the u s wage structure 1963 1987 application of quantile regression the 1980 s witnessed rapid changes in the structure of wages in the united states in this study recently developed techniques for quantile regression are applied to every march current population survey since 1964 and changes in the return to schooling and experience at different points of the wage distribution are examined the quantile regression technique parsimoniously describes the entire conditional wage distribution this conditional distribution is used to examine changes in within group wage inequality as measured by the difference between conditional quantiles two linear models are considered a simple one group model and a 16 group model the results suggest that the returns to schooling and experience differ across quantiles of the wage distribution but their patterns of change are similar significant differences in wage inequality are also found across the various skill groups the paper also presents a new imputation method for cps data

do village funds improve access to finance evidence from thailand summary this paper examines whether recently introduced village funds one of the largest microfinance programs ever implemented improve access to finance village funds are analyzed in a cross sectional approach in comparison to competing financial institutions we find first that they reach the target group of lower income households better than formal financial institutions second village funds provide loans to those kinds of borrowers who tend to be customers of informal financial institutions third village funds help to reduce credit constraints thus village funds provide services in the intended direction albeit to a seemingly limited degree

do regulated microfinance institutions achieve better sustainability and outreach cross country evidence in spite of increasing pressure on microfinance institutions mfis operating in developing countries to transform into regulated financial intermediaries to date no study has investigated whether regulated mfis actually achieve better financial results and reach more poor clients than nonregulated mfis this article explores the impact of regulation on mfi performance using newly released data for 114 mfis from 62 countries in an empirical model where performance is specified as a function of mfi specific regulatory macroeconomic and institutional variables consistent with recent cross country evidence on the impact of banking regulations on bank performance barth et al 2004 this article finds that regulatory involvement does not directly affect performance either in terms of operational self sustainability or outreach the article also finds that less leveraged mfis have better sustainability the policy implication is that mfis transformation into regulated financial institutions is may not

semiparametric estimation of selection models some empirical results among the central theoretical developments in the econometric analysis of nonexperimental microeconomic data has been the analysis of selectivity bias following the work of james heckman 1974 statistical techniques were developed in the 1970s to consistently estimate the parameters of these models one potential drawback to the application of these techniques is their sensitivity to the assumed parametric distribution of the unobservable error terms in the model in recent years a number of estimation methods for selection models have been developed which do not impose parametric forms on error distributions these methods are termed semiparametric since only part of the model of interest the regression function is parametrically specified while the statistical theory of these semiparametric estimators has received much attention practical applications of the methods are lacking an exception being the paper by joel horowitz and george neumann 1987 in this paper we use semiparametric methods to reanalyze data on the labor supply of married women first studied by thomas mroz 1987 using parametric methods the object of this reanalysis is to determine whether mroz s results are sensitive to his parametric assumptions

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

interpreting aggregate wage growth the role of labor market participation a new and easily implementable framework for the empirical analysis of the relationship between aggregate and individual wages is developed aggregate real wages are shown to contain three important bias terms one associated with the dispersion of individual wages a second deriving from compositional changes in the selected sample of workers and a third reflecting the distribution of working hours their importance for interpreting the path of aggregate wages and of the returns to education for recent experience in britain is highlighted a close correspondence between the estimated biases and the patterns of differences shown by aggregate wages is established

access to capital and agrarian production organisation there are two problems both universal that entrepreneurs in any economy must contend with firstly an agent generally has access only to a limited amount of working capital secondly workers hired by an agent are subject to moral hazard and this necessitates their supervision this paper models for an agrarian economy the constraints imposed on entrepreneurs activities by these two problems and endogenously determines the various organisational forms of production as well as the allocation of resources that will obtain with a simple model we endeavour to explain a diverse set of empirical observations pertaining to the less developed countries in terms of the general processes that determine the distribution of income among the various agents and the hierarchical relationships that develop among them agricultural production typically involves a period of several months between the time the inputs are purchased and the time the output is marketed access to working capital and hence to the credit market thus plays an important role in a farmer s production decisions the distribution of access to credit in turn tends to be an important determinant of income distribution in poor agrarian economies credit is invariably rationed according to the ability to offer collateral the amount of working capital a farmer can mobilise therefore depends on the amount of land he owns which is often a good proxy for his overall wealth and thus his ability to offer collateral further since hired hands have a propensity to shirk they need to be supervised and therefore the

human capital discrimination and the gender wage gap in bangladesh summary this paper investigates changes in the gender wage gap in bangladesh over the period 1999 2009 the gap in average wages between men and women decreased by 31 over this period this paper shows that a key driver of this change was an improvement in female educational qualifications it also demonstrates that the gender wage gap across the wage distribution narrowed much more at the lower end of the wage distribution than at the upper end it attributes this mainly to a decline in discrimination against women implications for policies aimed at more equal access to education and enforcement of equal pay legislation in bangladesh are also identified

does access to formal agricultural credit depend on caste summary this paper analyzes whether caste impedes access to formal agricultural credit in india credit is provided mainly through cooperative and commercial banks using national data we find that cooperative banks discriminate against lower caste borrowers and find weak evidence that commercial banks instead bias lending in their favor in accordance with affirmative action policies we compare the organizational structures of the two types of bank and explain discrimination by cooperative banks in terms of interest group capture at the district level by showing that discrimination takes place in those districts where higher castes dominate

making the most out of programme evaluations and social experiments accounting for heterogeneity in programme impacts the conventional approach to social programme evaluation focuses on estimating mean impacts of programmes yet many interesting questions regarding the political economy of programmes the distribution of programme benefits and the option values conferred on programme participants require knowledge of the distribution of impacts or features of it this paper presents evidence that heterogeneity in response to programmes is empirically important and that classical probability inequalities are not very informative in producing estimates or bounds on the distribution of programme impacts we explore two methods for supplementing the information in these inequalities based on assumptions about participant decision making processes and about the strength in dependence between outcomes in the participation and non participation states dependence is produced as a consequence of rational choice by participants we test for stochastic rationality among programme participants and present and implement methods for estimating the option values of social programmes

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

delayed formal credit bribing and the informal credit market in agriculture a theoretical analysis abstract the paper presents a theory of interest rate determination in the informal credit market in backward agriculture the market for informal credit is created by the delay in disbursement of formal credit the delay is controlled by the official of the formal credit agency and he is bribed by the farmer to reduce the delay the official and the moneylender play a non cooperative game in choosing the bribing rate and the informal interest rate respectively the informal sector interest rate and the effective formal sector interest rate incorporating the bribe are equal in equilibrium agricultural price and credit subsidy policies may raise the interest rate in the informal credit market

household sectoral choice and effective demand for rural credit in india an analysis of the icrisat data from three indian villages raises concern about the extent of rationing mechanism inhibiting the spread of formal credit in rural india where a significant proportion of households do not have any outstanding loan or borrow from the informal sector only a limited dependent econometric analysis of the factors jointly determining household sectoral choice and effective demand for informal loan conditional on whether a formal loan is available suggests that compared to formal loan easy and adequate access and prompt recovery are significant determinants of the popularity and viability of informal rural credit among sample households also some households substitute labour income to ease the extent of credit thus rationing of the formal credit is not the only factor inhibiting the spread of formal credit in the study villages

remittances and financial inclusion evidence from el salvador this paper investigates the impact of remittances on financial inclusion this is an important issue given recent studies showing that financial inclusion can have significant beneficial effects on households using household level survey data for el salvador the authors examine the impact of remittances on households use of savings and credit instruments from formal financial institutions they find that although remittances have a positive impact on financial inclusion by promoting the use of deposit accounts they do not have a significant and robust effect on the demand for and use of credit from formal institutions if anything by relaxing credit constraints remittances might reduce the need for external financing from financial institutions while at the same time increasing the demand for savings instruments

earnings distribution of cuban immigrants in the usa evidence from quantile regression with sample selection abstractthis article analyses the conditional earnings distribution for cuban immigrants in the usa considering buchinsky sample selection in a quantile regression model the test proposed by huber and melly to test the independence between error terms and regressors conditional on the selection probability is also considered this is the first attempt in the migration literature to use quantile regression with sample selection the data used come from the us american community survey the results show that the hypothesis of conditional independence is not rejected and increments in earnings associated with the usual socioeconomic characteristics in labour studies vary between the cohorts considered the main conclusions are that a decline in returns from education may be a sign that a high level of education no longer provides a competitive advantage and that being a black person is associated with substantially lower earnings regardless of the individuals position in the earnings distribution this

rural financial markets in developing countries their use and abuse until recently the use of agricultural credit as a developmental tool seemed clear and straightforward most concerned people believed that increases in the volume of cheap credit were necessary to boost agricultural production and that the rural poor could be brought into the mainstream of development through supervised credit programs it seemed that certain ideal types of rural credit institutions offered the promise of meeting farmers credit needs and that experience in the industrialized countries with cooperatives and specialized agricultural finance institutions could be effectively transplanted to low income countries this collection of readings highlights facets of rural financial markets that have often been neglected in discussions of agricultural credit in developing countries it moves beyond a narrow concern with the simple provision of credit to a broad consideration of the performance of rural financial markets and of ways to improve the quality and range of financial services for low income farmers it reflects new thinking on the design administration evaluation and policy framework of rural finance and credit programs in developing countries

the sensitivity of an empirical model of married women s hours of work to economic and statistical assumptions this study undertakes a systematic analysis of several theoretic and statistical assumption s used in many empirical models of female labor supply using a singl e data set psid 1975 labor supply data the author is able to replic ate most of the range of estimated income and substitution effects fo und in previous studies in this field he undertakes extensive specif ication tests and finds that most of this range should be rejected du e to statistical and model misspecifications the two most important assumptions appear to be the tobit assumption used to control for sel f selection into the labor force and exogeneity assumptions on the wi fe s wage rate and her labor market experience copyright 1987 by the econometric society

estimating outcome distributions for compliers in instrumental variables models in imbens and ingrist 1994 angrist imbens and rubin 1996 and imbens and rubin 1997 assumptions have been outlined under which instrumental variables estimands can be given a causal interpretation as a local average treatment effect without requiring functional form or constant treatment effect assumptions we extend these results by showing that under these assumptions one can estimate more from the data than the average causal effect for the subpopulation of compliers one can in principle estimate the entire marginal distribution of the outcome under different treatments for this subpopulation these distributions might be useful for a policy maker who wishes to take into account not only differences in average of earnings when contemplating the merits of one job training programme vs another we also show that the standard instrumental variables estimator implicitly estimates these underlying outcome distributions without imposing the required nonnegativity on these implicit density estimates and that imposing non negativity can substantially alter the estimates of the local average treatment effect we illustrate these points by presenting an analysis of the returns to a high school education using quarter of birth as an instrument we show that the standard instrumental variables estimates implicitly estimate the outcome distributions to be negative over a substantial range and that the estimates of the local average treatment effect change considerably when we impose nonnegativity in any of a variety of ways

does school quality matter returns to education and the characteristics of public schools in the united states this paper estimates the effects of school quality measured by the pupil teacher ratio average term length and relative teacher pay on the rate of return to education for men born between 1920 and 1949 using earnings data from the 1980 census we find that men who were educated in states with higher quality schools have a higher return to additional years of schooling rates of return are also higher for individuals from states with better educated teachers and with a higher fraction of female teachers holding constant school quality measures however we find no evidence that parental income or education affects average state level rates of return

coping with the energy crisis impact assessment and potentials of non traditional renewable energy in rural kyrgyzstan the kyrgyz energy sector is characterised by a dramatic energy crisis that has deprived a substantial part of the population from access to energy non traditional renewable energy sources have emerged as a promising alternative in providing basic energy services to the rural poor based on qualitative interview data from local households and project planners this study sets out to assess impacts limitations and barriers of non traditional renewable energy projects in rural areas in kyrgyzstan this study argues that recent renewable energy efforts from multilateral international agencies the private sector and nongovernmental organisations exhibit great potential in creating tangible benefits and improving basic energy services but have so far been inefficient in establishing and replicating sustainable and long term energy solutions existing practices need to be improved by attaching greater importance to the capacities and real needs of the rural poor the guidance of integrated programmes and policies along with alternative financing schemes and awareness raising are urgently needed to leverage local success stories and to facilitate a sustainable energy development in rural kyrgyzstan

strengthening financial innovation in energy supply projects for rural exploitations in developing countries abstract sustainable energy supply models are needed to achieve the millennium development goals established by the united nations for 2015 on the other hand sustainability of agricultural exploitations in rural areas is a pre requisite to achieve the objective of halving the proportion of people that lives in poverty and productivity of such exploitations is closely related to energy supply this article analyses the results of a survey of experts suggesting that there may be good chances to innovate in the financing of agricultural electrification projects in developing countries the experts opinion suggests that new sources of financing could be mobilised and oriented towards the promotion of sustainable initiatives in developing countries financial mechanisms should be adapted to the characteristics of decentralised systems of energy production with renewable sources or with mixed technologies in order to overcome the barriers derived from the high initial price of the applications and to the specific conditions of the agricultural sector the participation of funds from the beneficiaries and the incorporation of the beneficiaries in the initial phases of project organisation would allow for the development of productive solutions with a higher potential to generate resources and to articulate sustainable proposals

the dynamics of changes in the female wage distribution in the usa a quantile regression approach this paper examines the female wage structure focusing on changes at different points in the wage distribution newly developed quantile regression methods are used in analysing data from the march current population survey the results show that while the most significant changes for the less skilled women took place at the bottom of the wage distribution for the more skilled groups changes occurred at both ends of the distribution consequently wage inequality decreased for the high school graduates and increased for the younger college graduates furthermore the more highly skilled women experienced the steepest gain in wages regardless of their position in the distribution 1998 john wiley sons ltd

changes in the distribution of male and female wages accounting for employment composition using bounds this paper examines changes in the distribution of wages using bounds to allow for the impact of nonrandom selection into work we show that worst case bounds can be informative however because employment rates in the united kingdom are often low they are not informative about changes in educational or gender wage differentials thus we explore ways to tighten these bounds using restrictions motivated from economic theory with these assumptions we find convincing evidence of an increase in inequality within education groups changes in educational differentials and increases in the relative wages of women

gender wage gap and the role of skills and tasks evidence from the austrian piaac data set we analyze the gender differences in skills tasks and skill matching of workers and the impact of these factors on the gender wage gap using the survey of adult skills a product of the oecd pro

credit rationing in rural credit markets of india this article analyses the prevalent situation of the formal financial institutions fis in rural india using data from national sample survey 54th round january june 1998 we use sample selectivity model to examine the sanction of the loan by the fis as a two stage process we model the choice of the household s credit requirement using an unordered choice model namely a multinomial logit model our results reveal that the rural households are considerably credit constrained the households who do not have an account in a fi have a lower chance of obtaining the loan and households who are credit constrained have relatively lower land holding and they do not possess livestock households who borrow for nonfarm purpose exhibit a lower chance of obtaining credit compared to those households who borrow for farm business village level infrastructure plays an important role in determining the credit rationing behaviour in rural india

intersectoral labor mobility and the growth of the service sector one of the most striking changes in the u s economy over the past 50 years has been the growth in the service sector between 1950 and 2000 service sector employment grew from 57 to 75 percent of total employment however over this time the real hourly wage in the service sector grew only slightly faster than in the goods sector in this paper we assess whether or not the essential constancy of the relative wage implies that individuals face small costs of switching sectors and we quantify the relative importance of labor supply and demand factors in the growth of the service sector we specify and estimate a two sector labor market equilibrium model that allows us to address these empirical issues in a unified framework our estimates imply that there are large mobility costs output in both sectors would have been double their current levels if these mobility costs had been zero in addition we find that demand side factors that is technological change and movements in product and capital prices were responsible for the growth of the service sector

caste and credit a woeful tale this paper examines caste based differences in farmers access to bank loans in rural india we investigate whether banks practice taste based discrimination on the basis of caste in order to identify potential discrimination we consider loan applications and approval decisions separately we find significant inter caste differences in application rates and evidence of discrimination against scheduled tribe borrowers at the approval stage to rule out the role of statistical discrimination we simulate unobserved credit histories with various distributions evidence for taste based discrimination persists despite accounting for unobservables however we find that this discrimination does not affect small farmers

the changing nature of gender selection into employment europe over the great recession the aim of this paper is to evaluate the role played by selectivity issues induced by nonemployment in explaining gender wage gap patterns in the eu since the onset of the great recession we show that male selection into the labour market traditionally disregarded has increased this is particularly the case in peripheral european countries where dramatic drops in male unskilled jobs have taken place during the crisis as regards female selection traditionally positive we document mixed findings while it has declined in some countries as a result of increasing female lfp due to an added worker effect it has become even more positive in other countries this is due to adverse labour demand shifts in industries which are intensive in temporary work where women are over represented these adverse shifts may have more than offset the rise in unskilled female labour supply

renewable energy technology uptake in kazakhstan policy drivers and barriers in a transitional economy kazakhstan has considerable renewable energy potential the development of which can provide significant environmental economic and social benefits the country s national low carbon energy strategy aims to bring the share of renewables in electricity production to 50 by 2050 despite the considerable renewable energy resource base and ambitious deployment targets the current contribution of non hydro renewable energy to final electricity demand is less than one percent adoption of renewable energy technologies in a fossil fuel resource rich country like kazakhstan remains a big challenge but current low oil prices and a weakening economy may offer new opportunities deploying an analytical hierarchy process methodology we identify the most significant barriers to uptake of renewable energy in the context of the electricity sector the main factors preventing the penetration and scale up of renewables include a political and regulatory framework which supports and promotes a continued focus on fossil fuels supported in part by regional geopolitics a lack of awareness of sustainable alternative energy generation systems and a combination of social poverty and poor education in communities that are most likely to benefit from broadly distributed renewable technologies market conditions driven by current electricity tariffs inefficient but incumbent power technologies and a high risk business environment ranking barriers by importance will provide practitioners and regulators a mechanism to improve policies and incentivize renewable energy uptake in kazakhstan and other resource rich transition economies in central asia

the changing distribution of male wages in the uk this paper uses microeconomic data from the u k family expenditure surveys fes and the general household surveys ghs to describe and explain changes in the distribution of male wages since the late 1970s wage inequality has risen very fast in the u k and this rise is characterized both by increasing education and age differentials we show that a large part of the changes in the u k can be summarized quite simply as increases in eduction differentials and a decline of growth of entry level wages which persist subsequently this fact we interpret as cohort effects we also show that like in the u s an important aspect of rising wage inequality is increased within group wage dispersion finally we use the ghs to evaluate the role of alternative education measures

interactions between institutional and informal credit agencies in rural india in an attempt to expand rural credit and displace the village moneylender india created a system of rural cooperatives in the 1950s and expanded branch banking into rural areas in the 1970s this article examines how these measures affected the rural market it begins with the question of how large the expansion of institutional credit has been and the extent to which it has dislodged the village and nonresident moneylenders a detailed comparison of three major surveys of the indian rural credit market suggests that in various guises the moneylender is still a major source of loans the article also examines the weak evidence on intermediation between the formal and informal sectors a formal model of the interaction between the informal moneylender and institutional lender is constructed under a variety of assumptions about the exclusivity of loan contracts and the competitive structure of the informal sector the conclusions are drawn together in the form of five proposals for public policy
