the private wage sector in cote d ivoire homogeneity or heterogeneity one dominant feature of economic development is change in the structure of the economy some sectors expand while others shrink in response to changes in output markets considerable adjustments must take place in factor markets as well development will therefore proceed more speedily when barriers in the factor markets are minimal whether or not barriers in the labor market exist macroeconomic discussions of labor markets usually assume uninhibited flows between sectors 13 similarly a large literature on earnings of wage workers has treated the wage sector as a homogeneous part of the labor market yet if the wage sector is heterogeneous model estimates have no empirical meaning and policy recommendations have no foundation

smoking drinking and income in an effort to increase understanding of the alcohol income puzzle the finding that drinking appears to lead to higher income this paper presents maximum simulated likelihood estimates of a system of limited dependent variables governing smoking and drinking patterns and income with all else held constant moderate drinking is associated with 10 percent higher income and heavy drinking associated with 12 percent higher income than drinking abstention smoking is associated with larger effects on income than drinking single equation estimates suggest smokers earn 8 percent less than nonsmokers and the smoking penalty rises to 24 percent after correcting for endogeneity

what price drug use the contribution of economics to an evidence based drugs policy abstract this paper presents a review of the recent economics literature in the area of illicit drug use particular attention is paid to the economics of addiction and the rational addiction model the welfare economics framework for analysing the social costs of drug use and the attempts that have been made by economists to evaluate recent or proposed policy interventions a dominant theme in this review is the problem of poor data availability this is particularly true when it comes to implementing the rational addiction model but it is also apparent in the literature on estimating the costs of illicit drug use to society as a whole one of the main conclusions of this review is that until recently public policy has not been particularly influenced by research carried out by economists it is not clear whether this is because economists have had to grapple with inadequate data and hence their conclusions are couched in uncertainty or whether it is because drugs researchers have assumed a very limited role for economists in their analysis

home energy use in nine oecd countries 1960 1980 abstract government institutions and individuals have responded to fluctuations in energy supply and price with the implementation of policies and the initiation of conservation while these activities have resulted in noticeable conservation of energy primarily through behavioural actions further savings could be achieved through the exchange of information regarding promising policies and technologies toward this end data on residential sector energy use for nine oecd countries canada denmark france west germany italy japan sweden the uk and the usa have been collected over the period 1960 1980 and have been analysed using both indicators of energy use intensity and econometric methods

the morning after alcohol misuse and employment problems using a rich recent and nationally representative longitudinal survey specifically designed to examine alcohol use and associated problems we investigate the effects of alcohol misuse on a series of understudied and perhaps less common employment problems such problems include being fired or laid off from a job sustained unemployment and conflicts with a supervisor and or co worker after controlling for time invariant omitted variables via fixed effects estimation we find evidence that three measures of alcohol misuse are significantly related to employment problems the results offer new information on the potential adverse labour market effects of alcohol misuse and shed light on potential mechanisms through which alcohol misuse may impact intensive labour supply and or wages

do drinkers know when to say when an empirical analysis of drunk driving this paper presents empirical evidence that an individual s decision to drive while drunk is negatively affected by the expected full price of driving drunk the analysis usa a unique data set containing information on self reported drunk driving matched to state level drunk driving policies as well as to state excise taxes on beer these are hypothesized and found to affect drunk driving further we find interesting racial differences but surprisingly small differences by gender in the effect of socioeconomic and policy variables on drunk driving propensities

estimating wage discrimination in the labor market if labor supply curves are not perfectly inelastic wage discrimination induces some minority workers to leave the labor force studies of discrimination that focus only on wage differentials overlook these disincentive effects on minority employment

the labor market effects of disability discrimination laws we present new evidence on the effects of disability discrimination laws based on variation induced by state level antidiscrimination measures passed prior to the americans with disabilities act ada the evidence expands upon other research that focuses solely on the impact of the ada by using a quasi experimental framework that generates treatment and comparison groups we find that disability discrimination laws are associated with lower relative earnings of the disabled with slightly lower disabled relative labor force participation rates but are not associated with lower relative employment rates for the disabled once we control for preexisting employment trends among the disabled

impact of off farm income on food expenditures in rural bangladesh an unconditional quantile regression approach this study examines the effects of off farm income on food expenditures of rural bangladeshi households our analysis yields unbiased estimates of the unconditional impact of off farm income on food expenditures and reveals the heterogeneous effects that occur across the distribution of total food consumption expenditures the findings suggest that the impacts of off farm income are uniformly positive across the unconditional quantile regression and significantly increase food consumption expenditures for all quantiles except for the 25th quantile in addition we found that schooling experience and location of the household increase the food expenditures of rural households most importantly this article argues that female headed rural households in which the female works off the farm tend to have significantly lower food expenditures

the saving behaviour of a two person household the facts that wives are typically younger than their husbands and that women typically live longer than men imply that wives may have more incentive to save for old age than do husbands a theoretical model of the determination of household saving and portfolio choice is introduced which takes into account differences in preferences for saving the most important result is that the level and the composition portfolio of saving and the time path of consumption are dependent on the distribution of income within the household women typically live longer than men and wives are typically younger than their husbands these two facts imply that preferences about saving for old age in married households with forward looking members may differ between husband and wife this paper presents a theoretical analysis of saving and portfolio behaviour if the members of the household have differ ent preferences over future consumption as compared to current consump tion the analysis stands in contrast to unitary models of household intertemporal allocation which assume that the household has a single utility function thus this paper is a contribution in a novel context to the burgeoning literature on intra household decision making the base case analysis is for a simple two person husband and wife1 two period model in which there is only one asset saving it is assumed that because of the two facts given at the start of the introductory paragraph the husband discounts the future more than the wife in section ii the implications of a non cooperative decision making process for the base case are derived see ulph 1988 for a non cooperative model of demand and

the impact of alcohol consumption on occupational attainment in england in this study we provide evidence on the effect of alcohol consumption on occupational attainment in england to do this we use samples of employees from the health survey for england between 1992 and 1996 we find that owing to the endogenous nature of alcohol consumption ols estimates may provide a biased picture of the impact of alcohol consumption on occupational attainment using various sets of instrumental variables we find positive and significant returns to moderate levels of drinking for male and female employees which drop off rapidly as consumption increases

the economic well being of the disabled 1962 84 this paper focuses on the disabled working age population and tracks the changes in their labor market performance their receipt of public income transfers and their economic well being over the 1962 1984 period the changes over time in these indicators are compared with those of the nondisabled population the paper concludes that from the 1960s until the mid 1970s the disabled improved their performance in the labor market their real earnings rose both absolutely and relatively the economic well being of disabled males also increased rapidly during this period however in the last half of the 1970s the earnings of the disabled population fell rapidly although the rapid growth of transfer income cushioned this fall until the late 1970s then and especially after 1980 the controversial retrenchment in disability benefit programs struck and the well being of the disabled fell further

wage discrimination against handicapped men and women the extent of discrimination against handicapped men and women is estimated in this paper observed wage differentials are corrected for selectivity bias the results indicate that almost one third of the wage differential for men and close to one half for women can be attributed to discrimination interestingly handicapped women are also subjected to sex discrimination

the production of functionality by the elderly a household production function approach this paper extends becker s model of the household production function of human capital to the production of elderly functionality in this model elderly functionality is produced with the direct inputs of assistive devices personal assistance and nutritional intake education endowment variables like genetic endowment and sex and health conditions like stroke determine the production function environment data from the survey of asset and health dynamics among the oldest old ahead are used to estimate a production function of bathing functionality using a two stage estimation procedure in the first stage input demands for the endogenous functionality inputs are estimated recognizing health heterogeneity the results suggest that reverses in functionality caused by age and health conditions can be partially compensated for by the use of assistive devices like grab bars and bathing equipment secure nutritional intake and moderate alcohol consumption however non inputs like chronic healt

impacts of disability on poverty quasi experimental evidence from landmine amputees in cambodia abstract this paper examines the impacts of disability on poverty in rural cambodia i combine a natural experiment and spatial blocking first i focus on amputation among adults due to landmines which is free from measurement errors and the onset of which is an exogenous shock second i conduct an original survey stratified by disability status within villages where people have shared the same local vulnerability to landmine accidents this research design enables matching analysis within small geographic areas treating demographic factors such as household formation and fertility as endogenous this quasi experimental study finds that amputation greatly reduces consumption and income but not subjective well being i e adaptation increasing poverty and augmenting its magnitude disability triggers a vicious circle of reduced work low earnings and limited accumulation of productive assets and social capital this work cum asset channel leads to adverse intergenerational effects on child schooling and child labor

quasi maximum likelihood estimation of multivariate probit models farm couples labor participation joint estimation of farmers farm and off farm work participation requires a multivariate probit model in which the number of equations is twice the number of household members where there are more than two such equations i suggest a quasi maximum likelihood method which requires only two levels of numerical integration the method maximizes the use of sample information given this numerical feasibility condition it is used for estimating a joint participation model of farm couples farm and off farm work the model yields conclusions about comparative advantages of men and women in farm off farm and housework which cannot be obtained with a more limited setup

disability cash transfers in the context of poverty and unemployment the case of south africa summary south africa s disability grant dg program has been criticized for its poor administration and the dependency culture it promotes this paper assesses the program s targeting effectiveness and its effects on labor supply using disability self reports and standard measures of economic well being the results suggest that dg s inclusion errors are relatively limited but exclusion errors are substantial and serious the paper also shows that increased leniency in disability screening policy in the gauteng province in the early 2000s does not appear to have altered labor market behaviors relative to northern cape a province where there was no change in policy

non farm work and food security among farm households in northern ghana this paper examines the impact of non farm work on household income and food security among farm households in the northern region of ghana we analyze the impact by employing propensity score matching method that accounts for self selection bias the matching results show that participation in non farm work exerts a positive and statistically significant effect on household income and food security status supporting the widely held view that income from non farm work is crucial to food security and poverty alleviation in rural areas of developing countries

measuring the effect of disability on labor force participation this paper estimates the effect of disability on labor force participation by using symptoms or diseases as instruments in a simultaneous equations model of endogenous reported disability and labor force participation the results show that each measure of disability explains a significant amount of variation in labor force participation though the two are not perfect substitutes there is only weak evidence of endogeneity of the disability variables for cases where there is evidence of endogeneity the bias it causes has the opposite effect of that hypothesized in the literatute i e stress causes health to deteriorate with labor force participation furthermore it has only insignificant effects on the coefficients for other variables

health and labor market performance the case of diabetes technological innovation has reduced the effect of diabetes diabetic behavioral modification in the face and expectation of medical improvement should lead to improved labor market outcomes this article uses three cross sectional data sets from 1976 1989 and 1992 to document improvements in diabetic labor market performance women diabetics have significantly increased their labor force participation while male diabetics have slightly reduced their participation relative to nondiabetics

disability earnings income and consumption using longitudinal data for the period 1968 2005 for a sample of male household heads we determine the prevalence of disability during the working years and examine how the extent of disability affects a range of outcomes including earnings income and consumption we have seven main findings first disability rates are high we divide the disabled along two dimensions based on the persistence and severity of their work limiting condition we estimate that a person reaching age 56 has a 53 percent chance of having been disabled at least once during his working years and a 19 percent chance that he has begun a chronic and severe disability second the economic consequences of disability are frequently profound ten years after disability onset a person with a chronic and severe disability on average experiences a 68 percent decline in earnings a 32 percent decline in after tax income a 22 percent decline in food and housing consumption and a 21 percent decline in food consumption third the various economic consequences differ sharply across disability groups the outcome declines for those with a chronic and severe disability are often more than twice as large as those for the average disabled fourth our findings show the partial and incomplete roles that individual savings family support and social insurance play in reducing the consumption drop that follows disability only about half of this most disabled group reports receiving social security disability insurance or supplemental security income fifth we find a noticeable fall in earnings and income prior to the onset of a reported disability consumption also falls somewhat suggesting that future disability is partially but incompletely predictable in the short run sixth time use and detailed consumption data further indicate that disability is associated with a decline in well being seventh the quantities we have estimated combined with elasticities from the literature allow us to examine the optimality of current compensation for the disabled we find that the current compensation for our most disabled group appears to be lower than is optimal

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

the impact of work limiting disabilities on earnings and income mobility this article uses the 1968 2007 waves of the panel study of income dynamics psid to examine how work limiting disabilities influence the intragenerational earnings and income mobility of individuals the results show that work limiting disabilities increase the probability of downward mobility for several years after onset furthermore the probability of being in the bottom portions of the distributions increases significantly not only during the year of onset but also for at least 10 years afterwards these results are more pronounced for those individuals suffering from a disability that is more chronic or severe in nature income from spousal earnings and government transfer payments offers some protection against disability s adverse effect with more protection being provided to those who are more chronically disabled

health and wage a simultaneous equation model with multiple discrete indicators in this article we propose all econometric approach for estimating the simultaneouls effects of health and wages in a structural equations framework in the theoretical works of grossmana 1972a 1972b health is viewed as anl elldogen1oulsly determined capital stock the demand for health should rise with the wage rate as the rate of return to health investment increases with wage onl the other hand better health should raise market productivity and hence wages since health capital is an abstract theoretical concept it can hardly be measured quantitatively however most population surveys include various health indicators these indicators are usually discrete variables in the empirical work of grossman and benham 1974 these qualitative indicators are treated as continuous variables and two stage least squares estimation techniques are used this specification raises various econometric problems see e g goldberger 1964 pp 248 255 domencich and mcfadden 1975 and nerlove and press 1973 a satisfactory specification should take into account the discrete nature of the indicators our specification generalizes the dummy variables simultaneous equations system of heckman 1978 the measurement models of joreskog and goldberger 1975 and is closely related to the models of muthe n 1976 1979 muthen studies full information maximum likelihood procedures for estimation except for very simple cases this does not generally yield feasible or tractable procedures in this article we introduce a tractable procedure for statistical estimation and testing this specification and the estimation procedure is then applied to study the joint dependence of health and wages another departure of our approach from others is that we will test and correct the possible incompatibility of the various health capital indicators in the population surveys one may have subjective health indicators such as self evaluation of health which may reflect different populations perception of health we propose a statistical procedure for testing measurement compatibility and if required for correcting this problem this article is divided into two parts initially we describe the model specification estimation and statistical tests in a general simultaneous equation model with multiple discrete indicators in the second part of the paper we consider specification of a simultaneous equation model for health and wages the model

off farm work decisions of farm couples and land transfer choices in rural china although previous studies have widely examined the association between off farm work participation and land use behaviours of rural households little attention has been paid to the effects of the

oil supply disruptions and modelling methodologies the role of lp models abstract this paper has three main objectives first an argument is made that oil vulnerability is not a problem of the past but remains a significant concern for all oil consuming countries especially beyond 1990 second it is suggested that the severity of past disruptions can be attributed in part to physical and institutional constraints that prevented the oil market from reacting quickly to what were relatively minor supply disruptions the currently changing structure of the world oil market in particular the evolving sales agreements under which an increasing percentage of world oil is traded and the vertical integration of major opec members into areas such as refining could decrease the ability of the market to adjust to future disruptions third it is suggested that linear programming lp models offer unique capabilities in assessing the degree to which the world and domestic oil markets could adjust to short term supply disruptions given constraints on transport trade and refining possibilities imposed by the physical structures of those market sectors or by control of those sectors by increasingly powerful producing countries the assessment of this flexibility will help pinpoint areas needing attention and also contribute indirectly to the evaluation of short run demand elasticities for world oil the us department of energy s petroleum allocation pal model is used as an example of one lp model that can address such issues

off farm labour allocation decisions in small scale rural households in zimbabwe the double hurdle model is used to analyse the off farm labour decisions of small scale agricultural household members in the shamva district of zimbabwe the approach permits the joint modelling of the decision to participate in the labour market and the decision regarding the amount of time allocated to work results indicate that a number of variables notably gender education and assets indeed have effects which are qualitatively and quantitatively different in terms of participation and hours worked overall the empirical analysis confirms the importance of individual characteristics such as gender and education and household farm characteristics e g land area accessible to the household productive assets remittances and the agricultural terms of trade in influencing the labour market decisions of rural household members

the longitudinal structure of earnings losses among work limited disabled workers this paper asks what are the dynamic effects of disability on earnings unlike most of the previous literature it uses panel data and fixed effects methods are used to assess how the earnings of disabled workers depart from expected levels over many years before and after the date of onset of their disability the paper also examines how worker characteristics affect earnings losses from disability with particular attention paid to the age at which the person suffers onset disabled men are found to experience sharp drops in earnings that predate the measured date of onset earnings recover rapidly soon after onset with much of the immediate reduction made up in the first two post onset years a modest downward trendfollows resulting in significant long term losses in expected annual earnings of about 12 percent per year being older at onset nonwhite more chronically disabled and less educated cause the losses from disability to be larger and the recovery smaller a large portion of these differences across groups appear to derive from industry affiliation after onset the paper argues the facts are all consistent with a simple human capital explanation of the disability process

determinants of nonfarm earnings of farm based husbands and wives in northern ghana the nonfarm work participation decisions of married men and women in rural northern ghana were jointly and separately estimated for married couples through a bivariate probit using recent survey data selectivity bias was corrected for in estimating wage offer and labor supply equations using heckman s procedure education experience infrastructure distance to the capital and population density as well as interactions between education and infrastructure and between education and distance to the city were found to be significantly related to the probability of nonfarm labor market participation wages and the amount of nonfarm labor performed with significant differences by gender

work limiting health earnings and employment an analysis with sipp data abstractthis study examines the role of work limiting health conditions on employed people s earnings employment status and working hours and distinguishes between the different degree and sever

gender differences in labor market effects of alcoholism little is known about the role of specific health problems in affecting labor market productivity even less is known about gender differences in the labor market effects of such health problems current knowledge of health effects is based largely on samples composed exclusively of men a common practice in both economics and health research in the latter case even a congressional mandate to incorporate females in study samples is reputed to have had little effect patricia schroeder 1990 in this study we attempt to determine the structure of gender differences in labor market responses to alcoholism we use a relatively new data source that allows such comparisons by gender in a large community based sample previous studies have established that there are significant gender differences in labor market behavior differences in prevalence rates of alcoholism by gender are also well established it is estimated that 3 percent of females are currently suffering from alcoholism and twice that many have exhibited symptoms at some time for males the numbers are 10 and 20 percent respectively there is some medical evidence to indicate that physiologically women and men respond differently to alcohol for example a recent study suggests that women have greater vulnerability to the acute and chronic health conditions associated with alcoholism mario frezza et al 1990

income strategies among rural households in mexico the role of off farm activities abstract off farm activities generate on average more than half of farm households incomes in the mexican ejido sector participation in these activities helps reduce poverty and contributes to greater equality in the distribution of income this paper analyzes the determinants of access to off farm sources of income across households we find that education plays a major role in accessing better remunerated nonagricultural employment adults of indigenous ethnic origin suffer from an educational lag and have less access to off farm nonagricultural employment than non indigenous adults at identical educational levels the regional availability of off farm employment strongly affects participation in addition women are differentially limited by distance to urban centers in their ability to gain off farm employment

the welfare implications of increasing disability insurance benefit generosity abstract in order to evaluate whether workers are over or under insured through the disability insurance di program we develop a framework that allows us to simulate the benefits as well as the costs associated with marginal changes in payment generosity from a representative cross sectional sample of the population under the assumption that individuals are reasonably risk averse we find that the typical worker would value increased benefits somewhat above the average costs of providing them however whether the benefit increases tend to lower or raise utility when we average across all individuals in our sample is sensitive to assumptions that affect the relative marginal utility of income to disabled individuals

migration and incomes in source communities a new economics of migration perspective from china the objective of this paper is to understand the effects of china s migration on source communities and to discuss their policy implications we draw from new economics of labor migration nelm theory to understand how migration and migrant remittances can relax or tighten market constraints in china s rural economy using simultaneous equation econometric techniques and household survey data from china we estimate net sectorspecific effects of migration on rural household income focusing on farm production and self employment our econometric findings indicate that the loss of labor to migration has a negative effect on household cropping income in source areas however we provide evidence that remittances sent home by migrants positively compensate for this lost labor effect contributing to household incomes directly and indirectly by stimulating crop and possibly self employment production this finding offers evidence in support of the nelm hypothesis that remittances loosen constraints on production in the imperfect market environments characterizing rural areas in less developed countries taking into account both the multiple effects of migration and the change in household size participating in migration increases household per capita income between 14 and 30 percent migration and incomes in source communities a new economics of migration perspective from china china is experiencing the largest peacetime flow of labor out of agriculture ever witnessed in world history solinger 1999 rozelle et al 1999 despite the rapid expansion of labor migration china s work force is still disproportionately employed in agriculture compared to other countries at similar levels of per capita gdp taylor and martin 2001 hence as china s economy continues to expand the flow of labor to urban areas will continue and even accelerate johnson 1999 the massive flow of labor away from farms has intensified research interest in china s migration in recent years however as in the broader literature on migration in less developed countries most recent studies on china s migration have focused on determining the size and composition of the labor flow macroeconomic implications of increased migration and the effects of migration on urban areas zhao 1999 yang 1999 1997 less emphasis has been placed on researching the effects of migration on the rural communities that migrants leave even though evidence shows that the rural household in the village of origin is typically the central concern of all those involved in migration both those who leave and those who stay behind exceptions include wang and zuo 1999 bai 2001 moreover the recent increase in migration has left policy makers particularly concerned regarding the way source communities will be affected moa 1999 they are concerned that as labor flows away from farms food production and crop income will decline potentially threatening china s food security furthermore policy makers are concerned about the increasing gap between urban and rural household incomes if migration exacerbates this gap some fear that as it grows rural residents eventually will flood cities ill equipped to absorb them others fear that discontent over a rising urban rural income gap could even spill over into political unrest yang 1999 because china s markets and other modern economic institutions are still relatively undeveloped migration may play a pivotal role in creating or overcoming constraints caused by the lack of well functioning markets and or institutions knight and song 1999 benjamin and brandt 2000 the new economics of labor migration nelm literature analyzes migration as a household decision rather than as an individual decision stark 1991 the nelm hypothesizes that rural households facing imperfect market environments decide

labor market discrimination against hispanic and black men h ispanic american men have lower average wage rates than white non hispanics in 1975 the average white non hispanic male wage earner in the united states earned 5 97 an hour mexican men earned 4 31 72 as much as white non hispanics puerto rican men earned 4 52 76 as much and cuban men earned 5 33 89 as much as white non hispanics by way of comparison black men s average wages in 1975 were 4 65 78 of the white male wage several possible reasons for the hispanics lower wages come to mind among them are age and education geographic location immigration language difficulties and discrimination for example as shown in table 1 mexicans and puerto ricans are younger on average than the white non hispanic population and earnings tend to rise with age hispanics have lower average levels of education than white non hispanics and wages are positively associated with education many mexican americans live in the southwest where prices are relatively low moreover hispanics are more likely to be recent immigrants and to lack fluency in english than white non hispanics and so to be at a disadvantage in the labor market in addition there is a widespread belief that hispanics suffer from employment discrimination and cannot obtain the wages that their human capital would command if they were non hispanic whites how much of the wage differentials described above are due to each of these factors and to other inter group differences in wage related characteristics in particular how much impact does labor market discrimination have on the average hispanic man s wage and how does this compare with discrimination against blacks this paper provides answers to these questions a few other efforts have been made to analyze the relative earnings of hispanic and white nonhispanic men using 1960 and 1970 census data fogel 1966 poston and alvirez 1973 poston alvirez and tienda 1976 long 1977 and gwartney and long 1978 we use more recent data from the 1976 survey of income and education this data set enables us to measure wage rates more accurately and to specify the wage function more completely than does the census unlike previous analysts in estimating the wage function we take account of possible selectivity bias due to the distinction between average wage offers and average observed wages thus we hope to obtain a more accurate and up to date measure of labor market discrimination against hispanic men section ii explains the method used to separate the minority white non hispanic wage differential into the portions due to differences in average characteristics and the portion due to differences in unobserved factors and discrimination taking into account the possibility of selectivity bias in the observed wage sample section iii describes the data used in the study and the specification of the wage equation the breakdown of the observed wage differentials into components due to differences in participation in the wage and salary sector local price levels average characteristics and discrimination are presented in section iv section v summarizes our findings and discusses their implications for efforts to improve the economic situation of hispanics in the united states

the potential of land rental markets in the process of economic development evidence from china abstract we develop a model of land leasing with agents characterized by unobserved heterogeneity in ability and presence of an off farm labor market in this case decentralized land rental may contribute to equity and efficiency goals and may have several advantages over administrative reallocation the extent to which this is true empirically is explored using data from three of china s poorest provinces land rental markets and administrative reallocation reallocate land to those with lower endowments but the former are more effective in doing so and have a bigger productivity enhancing effect information on hypothetical market participation suggests that reducing transaction costs in land rental markets could help to realize significant additional productivity gains

disability and the labour market an analysis of british males this paper attempts using data from the british labour force survey 1996 to examine to what extent differences in labour market outcomes between able bodied and disabled men may be attributed to differences in endowments of human capital and associated productivity differences both labour force participation and selectivity corrected human capital equations are estimated and decomposition techniques applied to them using the methodology of baldwin and johnson baldwin m johnson w g 1994 labor market discrimination against men with disabilities journal of human resources xxix 1 winter 1 19 the employment effects of wage discrimination against the disabled are also estimated evidence of both substantial wage and participation rate differences between able bodied and disabled men are found which have implications for the operation of the 1995 disability discrimination act

illicit drug use unemployment and occupational attainment in this paper we use data from the british crime survey bcs to examine the effect of illicit drug use on labour market outcomes we find very little evidence to support any relationship between drug use hard or soft and occupational attainment however we find compelling evidence to suggest that drug use particularly the use of opiates cocaine and crack cocaine is associated with an increased risk of unemployment regardless of age or gender

gender differences in wage losses from impairments estimates from the survey of income and program participation this article develops a model of the relationships among functional impairments work disability employment participation and wage offers the model is estimated separately for males and females with data from the 1984 survey of income and program participation using estimates of disability and wage equations we rank 25 functional impairments by severity of disability and estimate the wage penalty associated with each impairment the results show that limitations to mobility and strength are relatively more disabling for males than for females while the opposite is true for limitations to sensory capacities and appearance

adolescent alcohol use sociability and income as a young adult we use data from the national longitudinal survey of adolescent health add health to study how sociability and adolescent alcohol use impact personal income as a young adult we find that factors which enhance not only individual sociability but also social interaction at the community level are positively linked to future earnings of adolescents adolescents whose friends and friends of friends have greater sociability reap long term labour market rewards into adulthood after adjusting for individual and community sociability the effect of teenage alcohol consumption on labour market earnings as young adults is reduced our results suggest that earnings premiums associated with adolescent alcohol consumption may be partially explained by social network dynamics

saying i don t the effect of the affordable care act young adult provision on marriage this paper investigates the effect of the affordable care act young adult provision on the propensity to marry the young adult provision expanded options for obtaining insurance coverage outside of marriage young adults affected by the provision might have less incentive to marry since one avenue for obtaining health insurance coverage is through marriage this paper examines this question by applying difference in differences type methods using the 2008 2013 american community survey results suggest that the provision is associated with decreases in the likelihood of marrying cohabitation and spousal health insurance coverage and an increase in the probability of divorce

employment wages and alcohol consumption in russia 1 introductionconcerns regarding the relationship between alcohol consumption and labor market productivity are well grounded if problem drinking or alcoholism is considered a disease then it may have depressant effects on labor market productivity causing reductions in employment earnings and other labor market outcomes mullahy and sindelar 1993 1996 kenkel and ribar 1994 however there is a medical literature that documents a u shaped relationship between alcohol consumption and the risk of cardiovascular disease according to this literature moderate drinkers have a lower risk of cardiovascular disease than do either abstainers or heavy drinkers beaglehole and jackson 1992 doll et al 1994 consistent with this evidence several economists have found a positive association between moderate drinking and earnings berger and leigh 1988 french and zarkin 1995 heien 1996 hamilton and hamilton 1997 zarkin et al 1998 macdonald and shields 2001 this article investigates the impact of alcohol consumption on employment and wages in russia the primary contributions of the article are twofold first it enhances the economic literature on the relationship between alcohol consumption and labor market behavior by using data from a longitudinal survey the use of a longitudinal data set enables the estimation of a fixed effects model which helps avoid the potential bias caused by unobserved individual factors not captured in cross sectional models the use of a fixed effects model is an important extension to the literature because the data sets used in previous studies are cross sectional and usually lack adequate variables that could serve as identifying instruments to control for the endogeneity of alcohol consumption 1 furthermore the richness of the data set used in this article allows for the application of three alternative measures of alcohol consumption in the empirical analysis this is important because the relationship between alcohol consumption and labor market outcomes may be sensitive to the alcohol measure that is used the second notable contribution of this article is that it provides the first empirical evidence on the association between alcohol consumption and labor market outcomes in russia excessive alcohol consumption is a widespread problem in russia where per capita alcohol consumption is around 14 liters per year the world health organization who considers 8 liters to be a sign that a country has a critical consumption level for health problems quinn judge 1997 furthermore the dramatic fluctuations in mortality rates experienced in russia over the past 15 years have generated considerable attention to the potential effect of alcohol consumption on the overall health of the russian population it is important to investigate how labor market outcomes would be affected by alcohol consumption in a country which demonstrates such dramatic fluctuations in alcohol consumption and mortality consistent with the previous studies cross sectional results generally support the hypothesis of an inverse u shaped relationship between alcohol consumption and wages and employment results from the fixed effect models are found to be quite different from those of cross sectional models the positive effect of alcohol consumption on employment disappears for both males and females once the individual fixed effects are controlled for the results of the wage model lend support to a small and linear return to alcohol consumption but the effects are significant only at the 10 level the fixed effects estimates are smaller in magnitude and estimated with less precision compared with cross sectional estimates section 2 reviews the previous literature section 3 discusses the conceptual issues and empirical strategy section 4 introduces the data set section 5 provides a discussion of the results and sensitivity analyses section 6 concludes the article

oil trends and prices in the next decade an aggregate analysis abstract in 1973 the oecd required about 0 5 tonnes of oil for the production of 1000 of output ten years after in 1983 for the production of output the requirements for oil had dropped to slightly over 0 3 tonnes this dramatic decline in the oil intensity of the oecd economy has led to a new era of oil oversupply marked by soft oil prices and uncertainty about the future market for petroleum products

alcohol and earnings does drinking yield a wage premium this paper examines the relationship between alcohol consumption and earnings for prime age males wage differentials for non moderate and heavy drinkers are estimated using a polychotomous choice model which accounts for the endogenous relationship be tween drinking and earnings we find that moderate alcohol consumption leads to increased earnings relative to abstention however heavy drinking leads to reduced earnings relative to moderate drinking heavy drinkers possess flatter age earnings profiles and attain lower returns for higher education than non and moderate drinkers these results are in contrast to previous research on substance abuse which finds no earnings drop off for heavy users

health a source of bias in labor supply models the inconsistency of the labor supply estimates using nonexperimental data has led to the costly income maintenance experiments that have taken place in various parts of the country in addition to being costly the analyses of experimental data also have their share of econometric problems 1 both experimental and nonexperimental studies face the problems of sample selection model specification and variable measurement in order to determine what effects the variables of interest have on labor supply all relevant factors must be included one of these control variables namely health is often included in a form which results in biased estimates in this paper we hope to show that the analysis of experimental and nonexperimental labor supply data must carefully address the health variable problem before meaningful estimates can be obtained in general three treatments emerge in the literature no control for health is used a binary variable which we shall call a disability variable is included in the model as an exogenous variable or the disability variable is used as a partitioning criterion to obtain a sample of able bodied men or women the disability variable is often the response to the question does your health prevent you from working altogether or does your health limit the kind or amount of work you could do this study will examine the bias created by each of these approaches and will suggest a method of measurement for health which does not produce biased estimates 2 health and labor supply

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item

employment unemployment and problem drinking the misuse of alcohol is estimated to result in enormous economic costs composed largely of reduced labor market productivity however there has been debate on this issue the purpose of this paper is to help to resolve this debate by presenting sound structural estimates of the relationship between measures of problem drinking and of employment and unemployment the analysis is based on the 1988 alcohol supplement of the national health interview survey we find that for both men and women problem drinking results in reduced employment and increased unemployment
