technology adoption under production uncertainty theory and application to irrigation technology we propose a theoretical framework to analyze the conditions under which a farmer facing production uncertainty due to a possible water shortage and incomplete information will adopt a more efficient irrigation technology a reduced form of this model is empirically estimated using a sample of 265 farms located in crete greece the empirical results suggest that farmers choose to adopt the new technology in order to hedge against production risk in addition we show that the farmer s human capital also plays a significant role in the decision to adopt modern more efficient irrigation equipment

women s schooling home teaching and economic growth the hypothesis that increases in the schooling of women enhance the human capital of the next generation and thus make a unique contribution to economic growth is assessed on the basis of data describing green revolution india estimates are obtained that indicate that a component of the significant and positive relationship between maternal literacy and child schooling in the indian setting reflects the productivity effect of home teaching and that the existence of this effect combined with the increase in returns to schooling for men importantly underlies the expansion of female literary following the onset of the green revolution

emigration and wages in source countries evidence from mexico abstract this paper examines empirically the effect of mexican emigration to the united states on wages in mexico using data from the mexican and us censuses from 1970 to 2000 the main result in the paper is that emigration has a strong and positive effect on mexican wages there is also evidence for increasing wage inequality in mexico due to emigration simple welfare calculations based on a labor demand supply framework suggest that the aggregate welfare loss to mexico due to emigration is small however there is a significant distributional impact between labor and other factors

two stage residual inclusion estimation addressing endogeneity in health econometric modeling the paper focuses on two estimation methods that have been widely used to address endogeneity in empirical research in health economics and health services research two stage predictor substitution 2sps and two stage residual inclusion 2sri 2sps is the rote extension to nonlinear models of the popular linear two stage least squares estimator the 2sri estimator is similar except that in the second stage regression the endogenous variables are not replaced by first stage predictors instead first stage residuals are included as additional regressors in a generic parametric framework we show that 2sri is consistent and 2sps is not results from a simulation study and an illustrative example also recommend against 2sps and favor 2sri our findings are important given that there are many prominent examples of the application of inconsistent 2sps in the recent literature this study can be used as a guide by future researchers in health economics who are confronted with endogeneity in their empirical work

female migration a way out of discrimination abstract in light of the recent feminization of migration we empirically explore to what extent worldwide female migration can be explained by perceived gender discrimination making use of unique individual level data we track women s intention and preparation to migrate from 148 countries between 2009 2013 and disentangle how individual perceptions of gender discrimination can foster or impede female migration across countries we perform extensive robustness checks to mitigate concerns about potential threats to identification posed by measurement error and unobservables our evidence indicates that women who do not feel treated with respect and dignity have a higher incentive to migrate abroad the likelihood that these migration intentions are turned into actual preparations however depends on more traditional determinants such as household income network effects and family obligations furthermore we also show that more intense gender imbalances in economic and political opportunities prevent women from actually moving abroad

a global assessment of human capital mobility the role of non oecd destinations discussions of high skilled mobility typically evoke migration patterns from poorer to wealthier countries which ignore movements to and between developing countries this paper presents for the first time a global overview of human capital mobility through bilateral migration stocks by gender and education in 1990 and 2000 and calculation of nuanced brain drain indicators building on newly collated data the paper uses a novel estimation procedure based on a pseudo gravity model then identifies key determinants of international migration and subsequently uses estimated parameters to impute missing data non oecd destinations account for one third of skilled migration while oecd destinations are declining in relative importance

the impact of private hospital insurance on the utilization of hospital care in australia abstractwe use the australian national health survey to estimate the impact of private hospital insurance on the propensity for hospitalization as a private patient we account for the potential endogeneity of supplementary private hospital insurance purchases and calculate moral hazard based on a difference of means estimator we decompose the moral hazard estimate into a diversion component that is due to an insurance induced substitution away from public patient care towards private patient care and an expansion component that measures a pure insurance induced increase in the propensity to seek private patient care our results suggest that on average private hospital insurance causes a sizable and significant increase in the likelihood of hospital admission as a private patient however there is little evidence of an expansion effect the treatment effect of private hospital insurance on private patient care is driven almost entirely by the substitution away from public patient care towards private

social security disability insurance applications awards and lifetime income flows this article provides new evidence about the impact of social security disability insurance on male labor force participation decisions based on estimates from a structural model of applications awards and state contingent lifetime income flows the lifetime framework makes it possible to consider long term opportunity costs associated with early labor force withdrawal and the disincentive to applications resulting from the statutory waiting period before benefits may be received estimation techniques account for the self selected nature of the pool of applicants when predicting the individual specific probability of acceptance and the opportunity costs of applying

women empowerment and economic development women empowerment and economic development are closely related in one direction development alone can play a major role in driving down inequality between men and women in the other direction empowering women may benefit development does this imply that pushing just one of these two levers would set a virtuous circle in motion this paper reviews the literature on both sides of the empowerment development nexus and argues that the interrelationships are probably too weak to be self sustaining and that continuous policy commitment to equality for its own sake may be needed to bring about equality between men and women

why have uk disability benefit rolls grown so much abstract over the last 30 years many countries including the uk have seen a dramatic rise in the share of the working age population receiving sickness and disability benefits hereafter disability benefits this is despite health levels that are generally thought to be slowly improving this paper describes the time path of uk disability benefit rolls and explores the existing uk literature together with literature from the usa in search of potential explanations for it since the early 1990s despite a number of detailed descriptive studies surprisingly little attention has been paid to quantifying the importance of the different factors believed to be driving the uk benefit roll growth this is all the more surprising given the continued growth and the level of policy attention recently and currently devoted to disability benefits in the uk

explaining applications to the u s disability system a semiparametric approach this study investigates the determinants of applications for u s disability benefits between 1986 and 1993 using a semiparametric discrete factor procedure separately for men and women approximating a dynamic optimization model the estimation accounts for a variety of potential biases that were unaddressed in prior studies our results indicate different responses of men and women to variations in policy measures past labor earnings and fringe benefits as well as benefit eligibility and benefit amounts clearly affect application behavior

disability transfers and the work decision of older men the potential causal relationship between the availability and generosity of disability transfers and the nonparticipation rates of older men is often asserted and much studied parsons 1980 haveman and wolfe 1984 leonard 1986 however estimates of the magnitude of this linkage vary widely the growth in transfer availability and generosity has been credited with from 30 to 100 percent of the significant post 1960 fall in older male participation rates the disparity in these research results stems primarily from 1 alternative sources of data that differentially constrain estimation of relevant expected wage and transfer incomes 2 specifications that are unable to distinguish income transfer from labor market effects and 3 reliance on measures of health status that are endogenous to the work leisure decision this study seeks to narrow the range of estimates by addressing each of these issues our utility maximization model of work status choice assumes that workers who differ in health status choose between the mutually exclusive options of working at the wage offered for their characteristics and accepting public or private disability transfers because the income flows in the two options are censored they are estimated using switching regression techniques as expectations conditional on exogenous individual characteristics hence accounting for the potentially endogenous process that separates wage earners from transfer recipients the marginal utilities of income from the two sources are allowed to differ because of stigma effects in the estimation we adjust the choice based nature of our sample employ longitudinal earnings data to measure expected changes in as distinct from the expected level of income in the two options and use a separately estimated latent health status measure largely purged of its endogeneity with the participation decision

endogenous regressor binary choice models without instruments with an application to migration abstract this paper shows identification of a semiparametric binary choice model containing an endogenous regressor when no outside instrumental variable is available a simple estimator an easy test for endogeneity and an empirical application to us migration data are provided

comparing features of convenient estimators for binary choice models with endogenous regressors abstract we discuss the relative advantages and disadvantages of four types of convenient estimators of binary choice models when regressors may be endogenous or mismeasured or when errors are likely to be heteroscedastic for example such models arise when treatment is not randomly assigned and outcomes are binary the estimators we compare are the two stage least squares linear probability model maximum likelihood estimation control function estimators and special regressor methods we specifically focus on models and associated estimators that are easy to implement also for calculating choice probabilities and regressor marginal effects we propose the average index function aif which unlike the average structural function asf is always easy to estimate

brain drain and economic growth theory and evidence we focus on the impact of migration prospects on human capital formation and growth in a small open developing economy we assume that agents are heterogeneous in skills and take their educational decisions in a context of uncertainty regarding future migrations we distinguish two growth effects an ex ante brain effect migration prospects foster investments in education because of higher returns abroad and an ex post drain effect because of actual migration flows the case for a beneficial brain drain bbd emerges when the first effect dominates i e when the average level of human capital is higher in the economy opened to migrations than in the closed economy we derive the theoretical conditions required for such a possibility to be observed using cross section data for 37 developing countries we find that the possibility of a bbd could be more than a theoretical curiosity

the rise in the disability rolls and the decline in unemployment between 1984 and 2001 the share of nonelderly adults receiving social security disability insurance income di rose by 60 percent to 5 3 million beneficiaries rapid program growth despite improving aggregate health appears to be explained by reduced screening stringency declining demand for less skilled workers and an unforeseen increase in the earnings replacement rate we estimate that the sum of these forces doubled the labor force exit propensity of displaced high school dropouts after 1984 lowering measured u s unemployment by one half a percentage point steady state calculations augur a further 40 percent increase in the rate of di receipt

psychiatric disorders and labor market outcomes evidence from the national comorbidity survey replication this paper uses the national comorbidity survey replication to estimate effects of recent psychiatric disorder on employment hours worked and earnings we employ methods proposed in altonji et al 2005a which use selection on observable traits to provide information regarding selection along unobservable factors among males disorder is associated with reductions in labor force participation and employment when selection on observed characteristics is set equal to selection on unobserved characteristics the magnitudes of these effects for males are 9 and 14 percentage point reductions for participation and employment respectively among females we find negative associations between disorder and labor force participation and employment but these estimates are more sensitive to assumptions about selection there are no effects of disorder on earnings or hours worked among employed individuals

an economic model of welfare stigma perhaps the most basic assumption of the economic theory of consumer demand is that more is better than less virtually all of the major propositions of consumer theory can in a certain sense be derived from the assumption that goods are good interestingly however this tenet seems to be violated by the behavior of many individuals in the low income population for many turn out to be eligible for a positive welfare benefit but do not in fact join the welfare rolls for example it has been estimated that in 1970 only about 69 percent of the families eligible for afdc aid to families with dependent children participated in the program see richard michel 1980 the corresponding percentage for afdc u the program for which families with an unemployed male are eligible was only 43 percent and the participation rate in the food stamp program was only 38 percent see maurice mcdonald 1977 this phenomenon has puzzled many investigators because such individuals do not locate on the boundaries of their budget sets consequently most investigators ignore the problem when studying the effects of welfare programs on behavior in this paper this seemingly irrational rejection of an increase in income is modeled as resulting from welfare stigma that is from disutility arising from participation in a welfare program per se 1 the existence of stigma has been amply documented in the sociological literature patrick horan and patricia austin 1974 lee rainwater 1979 where interviews of recipients have often uncovered feelings of lack of self respect and negative self characterizations from participation in welfare nevertheless this phenomenon has not been modeled and many questions consequently remain when is the disutility of participation strong enough to prevent participation shouldn t we expect individuals to weigh the disutility of participation against the potential benefit in their decisions what is the elasticity of participation with respect to the potential benefit also in a slightly different vein how are the work disincentives of welfare affected by stigma these questions have been given scant attention by economists yet they are crucial for our ability to predict the impact of various welfare programs on the lowincome population here these questions are addressed by modeling nonparticipation as a utility maximizing decision the model is developed and estimated for the afdc program 2 the model posits an individual utility function containing not just disposable income but

an intergenerational model of wages hours and earnings we develop a model in which a set of unobserved parental and sibling factors drives wages and work preferences these factors lead to similarities within families in wages work hours and earnings we estimate the model using data on parents and siblings in the national longitudinal surveys we find that parental and sibling wage factors influence the wages of both sons and daughters we also find strong similarities in work hours that run along gender lines and are due primarily to linkages in preferences the effect of wages on earnings is direct rather than through a labor supply response

disability capacity for work and the business cycle an international perspective important policy issues arise from the high and growing number of people claiming disability benefits for reasons of incapacity for work in oecd countries economic conditions play an important part in explaining both the stock of disability benefit claimants and inflows to and outflows from that stock employing a variety of cross country and country specific household panel data sets as well as administrative data we find strong evidence that local variations in unemployment have an important explanatory role for disability benefit receipt with higher total enrolments lower outflows from rolls and often higher inflows into disability rolls in regions and periods of above average unemployment in understanding the nature of the cyclical fluctuations and trends in disability it is important to distinguish between work disability and health disability the former is likely to be influenced by economic conditions and welfare programmes while the latter evolves in a slower fashion with medical technology and demographic changes there is little evidence of health disability being related to the business cycle so cyclical variations are driven by work disability the rise in unemployment due to the current global economic crisis is expected to increase the number of disability insurance claimants

the effect of illicit drug use on the wages of young adults this article examines the effects of cocaine and marijuana use on the wages of young adults the endogeneity of drug use in a wage equation is considered and a two stage least squares procedure is implemented the results suggest that increased use of marijuana or cocaine is associated with higher wages the positive relationship between drug use and the wage does not diminish with age i also investigate whether systematic differences in the return to measures of human capital investments can explain the positive relationship between drug use and wages

the retirement health nexus a new measure of an old puzzle traditional empirical models of retirement which use a self assessed health measure have often found that the wage rate has a surprisingly small effect on retirement using both a self reported health measure and one not based on self report subsequent mortality experience in a more general reduced form joint demand framework we test the importance of the interaction effects of health and retirement our findings are consistent with a joint determination of health and retirement the wage elasticity using either health measure is about equal to that found in a single equation model when a mortality measure is used but all three elasticities are five times greater than one found using self reported health in a traditional single equation model

illegal drug use and employment this article investigates the relationship between employment and the use of marijuana and cocaine for males in national longitudinal survey of youth data from 1984 and 1988 previous studies yielding mixed evidence may have inadequately accounted for the simultaneity between drug consumption and employment i implement an instrumental variable procedure that identifies drug use with variables that are empirically unrelated to employment including the regional cocaine price and a state marijuana decriminalization indicator results indicate that the use of each drug substantially reduces the likelihood of employment exogeneity tests reveal that standard probit estimates are severely biased toward zero

the demand for illicit drugs i introduction illicit drug use and alcohol abuse imposes significant costs on society and on the individual users these costs include increased crime health problems and employment problems because of these considerable costs government at all levels has made drug control and the control of alcohol abuse important priorities the federal government has undertaken an aggressive program of interdiction of drug shipments and eradication of drug crops in the field the federal government and the state governments have also increased their criminal justice efforts in analyzing the effect of government drug control programs economists have applied the conventional supply and demand model to illicit drug markets the model includes a demand function that is downward sloping with respect to price and a supply function that is upward sloping or horizontal with respect to price drug programs like interdiction and drug sanctions are assumed to reduce supply and raise equilibrium price other policy options such as some form of drug legalization could increase supply and reduce equilibrium price the effect of these policies on equilibrium quantity is dependent on the elasticity of demand and on whether demand shifts since not much is known about drug price elasticities the potential effects of various drug control policies remain a speculative exercise the purpose of this paper is to estimate the effects of alcohol and drug prices on alcohol use and drug participation both own price and cross price effects are estimated there are few prior empirical studies of the effect of drug prices because data have been difficult to acquire this paper makes use of newly available data on drug prices and is the first paper to link these data to a nationally representative drug use data set of 49 802 individuals estimates of drug price elasticities are important empirical evidence that drug sales can be characterized by market forces drug price elasticities are also important in estimating the likely impact of policies that affect drug prices and in estimating the effects of drug prohibition cross price elasticities are important to estimate since they suggest the likely effects of policies such as an increase in alcohol taxes on illicit drug participation and the effects of marijuana decriminalization on alcohol cocaine and heroin use ii prior studies while there are a number of prior studies of the effects of alcohol prices and policies there are few prior studies of drug prices and polices the reason for so few prior drug studies is the limited amount of data on drug prices and the limited options for linking these data to an individual record by residential area this study uses a new data set of cocaine and heroin prices from the drug enforcement agency that was linked to individual records by the office of applied studies at the substance abuse and mental health services administration leung and phelps 1993 provide a review of a number of recent alcohol demand studies the empirical literature provides considerable evidence that shows increasing the price of alcoholic beverages to decrease alcohol use alcohol demand studies generally estimate price elasticities for beer wine and spirits separately most studies employ aggregate data but a few use individual data studies using aggregate data find price elasticities for beer from about 2 to about 1 0 for wine from about 3 to about 1 8 and for spirits from about 3 to about 1 8 studies using individual data estimate price elasticities for beer from about 5 to about 3 0 for wine at about 5 and for spirits from about 5 to about 4 0 the few prior studies of the effect of decriminalization on marijuana use generally find that marijuana decriminalization has no effect on participation pacula 1994 thies and register 1993 dinardo and lemieux 1992 and johnston o malley and bachman 1981 all used samples of young people and found no effect of marijuana decriminalization

labor market effects of marijuana and cocaine use among young men using data on marijuana and cocaine use from the 1984 national longitudinal survey of youth the authors examine the hypothesis that drug use reduces labor market productivity as measured by wages from an analysis that controls for the probability of employment and the endogeneity of drug use they find that although long term and on the job use of marijuana negatively affected wages the net productivity effect for all marijuana users both those who engaged in long term or on the job use and those who did not was positive no statistically significant association was found between cocaine use and productivity

a structural model of social security s disability determination process we estimate a multistage sequential logit model reflecting the structure of the disability determination process of the social security administration ssa the model is estimated using household survey information exact matched to ssa records on disability adjudications from 1989 to 1993 under program provisions different criteria dictate outcomes at different steps of the determination process we find that without the multistaged structural approach effects of many important health disability and vocational factors are not readily discernible as a result split sample predictions of overall allowance rates from the sequential model perform considerably better than do those for the conventional allowed denied logit regression

disability insurance benefits and labor supply some additional evidence this article examines the effects of a change in the canada quebec pension plan c qpp disability benefits on the labor supply of older canadian workers i obtain my estimates by exploiting a large increase in benefits that only occurred in the qpp program which only operates in quebec while benefits in the cpp program which operates in the rest of canada were unaffected unlike the existing estimates from the united states as well as earlier canadian obtained by gruber i find that disability benefits are not associated with a large increase in the nonparticipation of older men

women s liberation what s in it for men the nineteenth century witnessed dramatic improvements in the legal rights of married women given that these changes took place long before women gained the right to vote they amounted to a voluntary renouncement of power by men in this paper we investigate men s incentives for sharing power with women in our model women s legal rights set the marital bargaining power of husbands and wives we show that men face a tradeoff between the rights they want for their own wives namely none and the rights of other women in the economy men prefer other men s wives to have rights because men care about their own daughters and because an expansion of women s rights increases educational investments in children we show that men may agree to relinquish some of their power once technological change increases the importance of human capital we corroborate our argument with historical evidence on the expansion of women s rights in england and the united states

why do disability benefit rolls vary between regions a review of the evidence from the usa and the uk mcvicar d 2006 why do disability benefit rolls vary between regions a review of the evidence from the usa and the uk regional studies 40 519 533 over the last 30 years many organization for economic co operation and development oecd countries have seen a dramatic rise in the share of the working age population receiving earnings replacement sickness and disability benefits the reasons behind this growth particularly for the usa but also to a lesser extent elsewhere have been extensively researched in the economics literature what have been less well researched are the large spatial differences in the size of disability benefit rolls that have emerged in some countries over this period the uk displays a distinct regional pattern where working age men and women in the north are considerably more likely to be claiming disability benefits than those in the south the usa has its own version of the north south divide with many southern states displaying disproportionately large disabilit

south south migration and discrimination against women in social institutions a two way relationship summary using the social institutions and gender index sigi from the oecd development centre this paper provides evidence on the two way relationship between discrimination against women in social institutions and south south migration on the one hand discriminatory social institutions in both origin and destination countries are an additional determinant of female migration on the other hand migration implies changes in discrimination against women according to the level of gender inequalities at destination specifically migration toward countries with low levels of discrimination promotes gender equality in social institutions at home while migration toward destinations with high levels of discrimination has the reverse effect

disability benefits replacement ratios and the labour market a time series approach in this paper a study of factors affecting the number of disability beneficiaries in norway is presented equations determining entry rates into the disability benefit system are estimated using aggregated time series data grouped by sex and age unemployment is found to influence disability entry the results regarding effects of the replacement ratio are ambiguous a model determining the number of beneficiaries including the estimated entry equations is presented the model is used to simulate the effect of counterfactual changes in exogenous variables on the number of disability beneficiaries

the effects of male and female labor supply on commodity demands we examine the effects of male and female labor supply on household demands and present a simple and robust test for the separability of commodity demands from labor supply using data on individual households from six years of the uk fes we estimate a demand system for seven goods which includes hours and participation dummies as conditioning variables allowance is made for the possible endogeneity of these conditioning labor supply variables we find that separability is rejected furthermore we present evidence that ignoring the effects of labor supply leads to bias in the parameter estimates

disability transfers self reported health and the labor force attachment of older men evidence from the historical record we use trends in self reported disability to gauge the impact of the growth of disability transfer programs on the labor force attachment of older working aged men our tabulations suggest that between 1949 and 1987 about half of the 4 9 percentage point drop in the labor force participation of men aged 45 54 and between one quarter and one third of the 19 9 point drop among men aged 55 64 represented a movement of men out of the labor force and onto the rolls of transfer programs targeted at the disabled since the expansion of transfer programs represents only one of the forces behind this movement these figures represent upper bounds on the impact of such programs on work force attachment

how different are the british in their willingness to move evidence from international social survey data drinkwater s and ingram p how different are the british in their willingness to move evidence from international social survey data regional studies this paper analyses people s willingness to move using data from the 1995 british social attitudes survey and international social survey programme the personal characteristics and sub regional indicators that are important in explaining the willingness to move within britain are identified it is also found that the willingness to move is only higher in a few other countries including the usa the equivalent desire to move is found to be much lower in eastern european countries and in several other european union member states compositional effects such as age and education are generally important in explaining differences in attitudes towards migration in comparison with other western economies however structural effects such as institutions history and culture tend to play a more dominant role in explaining differences compared with countries

cannabis use and its effects on health education and labor market success cannabis is the most popular illegal drug its legal status is typically justified on the grounds that cannabis use has harmful consequences empirically investigating this issue has been a fertile topic for research in recent times we provide an overview of this literature focusing on studies which seek to establish the causal effect of cannabis use on health education and labor market success we conclude that there do not appear to be serious harmful health effects of moderate cannabis use nevertheless there is evidence of reduced mental well being for heavy users who are susceptible to mental health problems while there is robust evidence that early cannabis use reduces educational attainment there remains substantial uncertainty as to whether using cannabis has adverse labor market effects

immigrant selectivity and wages the evidence for women in an effort to extend the analysis of selectivity to female immigrants this paper examines the impact of economic conditions at the time of migration on the subsequent wages of foreign born women in the united states in addition the variables chosen to describe the migration decision have been expanded to include the effects of household status and immigration policy these results are compared to previous results for men and provide additional evidence about how the context of the migration decision affects the subsequent success of immigrants in the united states the sample for this project comes from the april 1983 current population survey and consists of married native and foreign born women between the ages of 16 and 64 excerpt

estimation in a class of simultaneous equation limited dependent variable models estimation in a class of simultaneous equation limited dependent variable models is considered the minimum chi squared method is used to compare the asymptotic relative efficiency of marginal and new conditional maximum likelihood estimators for this class of models efficient minimum chi squared estimation procedures are described a two step algorithm based on a conditional maximum likelihood estimator provides a natural framework for both computing a linearized and locating the joint maximum likelihood estimator the unimodality of the simultaneous equation tobit likelihood function is proved and this model is used to illustrate the empirical application of some of the estimators considered in the paper the relative efficiency of these estimators in the simultaneous equation tobit model is examined in a set of monte carlo experiments many applications of microeconomic theory to individual data face the joint problems of censoring and simultaneity in particular the dependent variable under investigation may not be continuously observed and some of the conditioning variables representing the outcome of other decisions by the individual may be simultaneously determined smith and blundell 1986 developed an asymptotically efficient test for exogeneity or simultaneity in the simultaneous equation tobit model as a byproduct a conditional maximum likelihood estimator was obtained which is consistent under the alternative hypothesis of simultaneity nelson and olsen 1978 amemiya 1978 1979 and heckman 1978 consider a number of consistent marginal maximum likelihood estimators based on marginal maximum likelihood estimators of the reduced form parameters for the probit and tobit models in contrast the estimator derived from smith and blundell 1986 is based on the corresponding conditional maximum likelihood estimators this paper is concerned with estimation in a class of simultaneous limited dependent variable regression models which includes the simultaneous probit and tobit models as special cases analogous marginal and conditional maximum likelihood estimators to those of nelson and olsen 1978 amemiya 1978 1979 heckman 1978 and smith and blundell 1986 are derived and other new estimators are suggested the minimum chi squared approach discussed by ferguson 1958 malinvaud 1970 and rothenberg 1973 is used to compare the asymptotic relative efficiency of various estimators considered a simple two step algorithm based on the conditional maximum likelihood

alcoholism work and income this article reports on an empirical analysis of the relationships between alcoholism and income and working we show that the relationships between alcoholism and labor market success have important age or life cycle dimensions we present evidence that alcoholism may affect income more by restricting labor market participation than by affecting the wages of workers finally we demonstrate that the effects of alcoholism on earnings depend on the extent to which one controls for other covariates associated with alcoholism as such we suggest that there may be important indirect as well as direct effects of alcoholism on labor market success

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

the demand for cocaine by young adults a rational addiction approach abstract this paper applies the rational addiction model to the demand for cocaine by young adults in the monitoring the future panel the price of cocaine is added to this survey from the drug enforcement administration s system to retrieve information from drug evidence results suggest that annual participation and frequency of use given participation are negatively related to the price of cocaine in addition current participation frequency is positively related to past and future participation frequency the long run price elasticity of total consumption participation multiplied by frequency given participation of 1 35 is substantial

the early retirement decision new empirical evidence on the influence of health many studies have examined the influence of health on retirement but there may be problems with the various health measures used a major criticism of the most frequently used variables is that they may reflect ex post rationalizations of retirement in this paper i examine a variety of health variables focusing directly on the health measurement issue as it relates to retirement research new measures of health are developed with individual self evaluations of health status unlike most previous findings the empirical results suggest that economic variables play a more important role than health in retirement decisions

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

exogenous shocks and related goods drinking and the legalisation of marijuana abstract the paper uses the substitutability between goods to model the transmission to other products of a consumption shock to one product the framework is used to analyse the impact on drinking of legalisation of marijuana for all types of consumers for example the results indicate that legalisation would lead to approximately a 4 increase in marijuana consumption while beer wine and spirits consumption would fall by 1 2 and almost 4 respectively

imperfect tagging in social insurance programs abstract this paper derives the optimal benefit structure of an earnings insurance program when a characteristic or tag imperfectly identifies those unable to work with a two sided classification error the optimal program is a dual work incentive system with a work non work consumption differential maintained for the tagged and untagged just sufficient to induce the able in each group to work and with more generous payments to tagged than to untagged individuals of the same work status it includes premiums to program eligible individuals who work a price missing in the u s social security disability system and in earlier attempts to characterize the optimal disability program

help or hindrance religion s impact on gender inequality in attitudes and outcomes summary this paper investigates the effect of religiosity on attitudes toward gender equality using world values survey data results indicate that religiosity is strongly correlated with gender inequitable attitudes across countries further ols tsls and 3sls regression estimates reveal that gender inequitable attitudes are associated with negative effects on seven measures of gender equality of well being and public policy no single religion stands out as more gender inequitable than others the impact of religiosity is likely transmitted via stealth effects on everyday behavior in economic transactions in labor markets household resource allocation and government spending

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

out migration wealth constraints and the quality of local amenities the relation between income and migration intentions can be monotonically decreasing increasing or inverse u shaped dependent on the level of migration cost relative to wealth and if individuals are credit constrained using unique individual level data covering countries in three geographic regions sub saharan africa asia and latin america we show that migration intentions respond to individual wealth and that the pattern differs across the country groups studied in a manner compatible with the predictions of our simple model we also show that contentment with various dimensions of local amenities such as public services and security are key determinants of migration intentions
