economic determinants and consequences of self reported work disability this paper examines the determinants of and behavioral responses to self reported work disability in samples of older men and women stratified by race strong support is found for the hypothesis that economic factors as well as poor health influence the probability that individuals report health conditions limit the amount or kind of work they do in particular lower expected wage rates significantly raise the probability of reporting work disablement controlling for health status and health related job requirements the empirical analysis also shows that only a part of the reduced labor supply of disabled individuals is attributable to health conditions the policy and methodological implications of these findings are discussed

modelling long run scenarios this paper intends to draw overall lessons from a long term study on co2 emission in france a country with a rather low energy gdp ration and in which transition to non fossil based production of electricity has been achieved more generally it points out the importance of possible bifurcation effects and draws methodological and policy implications from these statements it discusses modelling approaches to the linkages between energy and the rest of economy and addresses the issue of difficulties in cost assessment analysis in the presence of several baseline scenarios finally it proposes a more encompassing definition of no regrets policies

the role of energy in productivity growth the objective of this paper is to analyze the role of energy in the growth of productivity the special significance of energy in economic growth was first established in the classic study energy and the american economy 1850 1975 by sam schurr and his associates 1960 at resources for the future for the period from 1920 to 1955 schurr noted that energy intensity of production had fallen while both labor and total factor productivity were rising the simultaneous decline in energy intensity and labor intensity of production ruled out the possibility of explaining the growth of productivity solely on the basis of substitution of less expensive energy for more expensive labor since the quantity of both energy and labor inputs required for a given level of output had been reduced technical change is also a critical explanatory factor an alternative explanation for growth of output with declining energy and labor intensity required an examination of the character of technical change this examination was motivated by the fact that from 1920 to 1955 the utilization of electricity had expanded by a factor of more than ten while consumption of all other forms of energy only doubled the two key features of technical change during this period were that the thermal efficiency of conversion of fuels into electricity increased by a factor of three and that the unusual characteristics of electricity had made it possible to perform tasks in altogether different ways than if the fuels had to be used directly schurr 1983 p 3 schurr 1982 has recently extended the analysis of energy and the american economy through 1981 for the period through 1969 his conclusions are as follows although the inverse relationship between total factor productivity and energy intensity virtually disappeared during the 1953 1969 period it is still noteworthy that high rates of improvement in total factor productivity were essentially not associated with increases in energy intensity 1982 p 6 schurr 1982 has analyzed the experience of the u s economy in the aftermath of the oil embargo of 1973 he points out that energy intensity of production has fallen steadily since 1973 and that the rate of decline accelerated sharply after the second oil price shock in 1979 following the iranian revolution he goes on to point out that

party systems and electoral volatility in latin america a test of economic institutional and structural explanations three different theoretical explanations are tested for the exceptionally high level of electoral volatility found in contemporary latin america economic voting institutional characteristics of political regimes and party systems and the structure and organization of class cleavages a pooled cross sectional time series regression analysis is conducted on 58 congressional elections and 43 presidential elections in 16 latin american countries during the 1980s and 1990s institutional variables have the most consistent effect on volatility while the influence of economic performance is heavily contingent upon the type of election and whether the dependent variable is operationalized as incumbent vote change or aggregate electoral volatility the results demonstrate that electoral volatility is a function of short term economic perturbations the institutional fragilities of both democratic regimes and party systems and relatively fluid cleavage structures

measuring and assessing capacity utilization in the manufacturing sectors of nine oecd countries following a tradition established by cassels klein and hickman we employ the economic theory of cost and production and define economic capacity output as that output at which short and long run average total cost curves are tangent to one another capacity utilization cu rates are then computed as the ratio of actual to capacity output we implement this framework empirically by specifying and estimating a translog variable cost function for the manufacturing sectors of nine oecd countries we find that by the end of the historical sample the early 1980s pervasive and chronic excess capacity exists while the average cost consequence of excess capacity was relatively modest in the 1960s the burden increased considerably after opec i and after opec ii the premium was as large as 15 of average total costs we also find that electricity and fuel price increases had small impacts on capacity output relative to that from labor or capital finally we adjust conventional measures of multifactor productivity growth for changes in cu and find that the adjusted growth is larger after 1973 than that based on traditional procedures

determinants of women s health status and health care utilization in a developing country a latent variable approach a latent variable representation of health is used in a system that determines health and various indicators of health and health care utilization for nicaraguan women estimates differ somewhat from standard estimates they imply that women s schooling increases health care utilization literate women report less disease incidence women s childhood backgrounds affect their adult health and health care utilization and general resources favor childbirth related care but women s full income favors general care the most significant result is that several important characteristics usually associated with development women s schooling household resources and women s labor force participation have inverse or no associations with women s health health status is hypothesized to be important in developing countries both as a direct indicator of welfare and because of its possible impact on productivity health care utilization also is of interest both because of its relation to health status and because it is a particular manifestation of demand and supply for a 1 modem service work on the determinants of health status and health care utilization in developing economies however is flawed because true health status is not directly observable the indicators of health status that have been used in empirical studies anthropometric measures days ill self reported or clinical disease records inputs such as nutrients and health care utilization indicesare imperfect indicators of underlying health status and generally do not give a congruent representation of that status thereby they may not measure adequately health status and their use may lead to biases in estimates and incorrect interpretations we use a latent variable methodology for the first time to explore health status and health care utilization in a developing country this approach employs systematic relations between various indicators of health status and health status itself and between health status and various related outcomes so that it is possible to estimate the determinants of health status and control for health status in other relations even though health status is not directly observed by using this methodology we obtain more satisfactory estimates of the determinants of health status and of health care utilization in a developing country context than previous estimates using direct but imperfect proxies this should improve the empirical bases for evaluating health and related policies in the developing world i latent variable model of health status and health care utilization in the human capital tradition of analysis of health individual health status is viewed as determined by individual demand factors given supply prices environment age and resources including genes health care utilization is a derived demand for a service which is used to produce better health to incorporate the latent variable representation of the unobserved health status we assume that the demand supply health status and health care utilization interactions as well as the relation of other health indicators to health status can be represented by the following linear system of relations

a probit latent variable model of nutrition information and dietary fiber intake nutrition information and intake data for a sample of u s household meal planners are used to estimate the effects of fiber specific information on dietary fiber intake the information variables are measured using survey questions on fiber content of foods attitude toward consuming fiber rich foods and awareness of fiber health links the evidence confirms the influence of nutrition information on fiber intake household income meal planner age smoking status vegetarian status race and ethnicity are major determinants of both information and intake education exerts a sizable intake effect by enhancing the information level direct and indirect effects of exogenous variables are reported

econometric studies in health economics a survey of the british literature this paper provides a survey of british applied econometric work in the field of health economics as well as reviewing the literature it suggests some avenues for future research it covers six main areas the supply of health care the demand for health care non medical influences on health market and non price rationing evaluation of health care systems and planning budgeting and monitoring mechanisms

long term and spillover effects of health shocks on employment and income abstract we use matching combined with difference in differences to identify the causal effects of sudden illness represented by acute hospitalizations on employment and income up to six years after the health shock using linked dutch hospital and tax register data an acute hospital admission lowers the employment probability by seven percentage points and results in a 5 percent loss of personal income two years after the shock there is no subsequent recovery in either employment or income there are large spillover effects household income falls by 50 percent more than the income of the disabled person

health and work in the family evidence from spouses cancer diagnoses abstract using canadian administrative data from multiple sources we provide the first nationally representative estimates for the effect of spouses cancer diagnoses on individuals employment and earnings and on family income our identification strategy exploits unexpected health shocks and combines matching with individual fixed effects in a generalized difference in differences framework to control for observable and unobservable heterogeneity while the effect of spousal health shocks on labor supply is theoretically ambiguous we find strong evidence for a decline in employment and earnings of individuals whose spouses are diagnosed with cancer we interpret this result as individuals reducing their labor supply to provide care to their sick spouses and to enjoy joint leisure family income substantially declines after spouses cancer diagnoses suggesting that the financial consequences of such health shocks are considerable

wages and hazardous working conditions the purpose of this paper is to provide a new empirical test for the existence of wage premiums paid to workers who are exposed to dangerous or unhealthy working conditions prior empirical studies have encountered problems with omitted ability data omitted working conditions data and measurement error the empirical model presented in this paper uses a difference specification to eliminate bias from omitted ability data by assuming that all hazardous working conditions are measured by a single endogenous unobserved variable this empirical model also eliminates bias due to omitted working conditions and measurement error the empirical model is estimated using the 1973 7 version of the quality of employment survey the unique data in this survey facilitate estimation of a model in which working conditions are assumed to be unobservable using a two stage technique for consistent and efficient estimation the empirical results reported in this paper show that a compensating difference for hazardous work

alcohol consumption and human capital a retrospective study of the literature grossman proposed an individual s health can be viewed as one aspect of their human capital following this line of thought a number of recent papers have reported a positive impact of alcohol consumption on earnings the rationale for the existence of such a relationship is the positive impact of alcohol on physical and mental health we conduct a meta analysis to determine whether such factors as the estimation technique the presence of ex drinkers in the sample possible sample selection bias and publication bias may all contribute to these findings an additional suggestion for the positive relationship between alcohol and wages is the presence of a common set of personality traits that determines drinking behaviour and also leads to higher earnings we examine this relationship by reviewing the literature that investigates if the personality influencing aspects of alcohol consumption influences measures of human capital we also survey the significant body of research that has examined how alcohol consumption has been found to influence educational outcomes and the work force participation of problem drinkers

the employment effects of wage discrimination against black men when labor supply curves are upward sloping wage discrimination against black men reduces not only their relative wages but also their relative employment rates using data from the 1984 survey o

growth accounting with intermediate inputs and the transmission of technical change abstract the aggregate rate of total factor productivity growth tfpg when there are intermediate inputs can be expressed either as a weighted average or as a weighted sum of the sectoral rates depending on the choice of sectoral rates being weighted the agrument that there is a magnification effect due to the transmission of tfpg through the intersectoral flows among sectors is therefore to be more illusory than real

nutrition and labor producvivity in agriculture estimates for rural south india using panel data for rural south india a fixed effects individual wage equation and farm production function are estimated that have calorie intake and nutritional status weight for height of workers as their arguments neither market wages nor farm output are observed to be responsive to changes in the daily energy intake of workers however both are highly elastic with respect to weight for height these results suggest that while the human body can adapt to inadequate nutrition in the short run it cannot adapt as readily to chronic malnutrition that eventually results in loss of weight for height copyright 1988 by mit press

do overarching mitigation objectives dominate transport specific targets in the eu this research investigates if the stringent 2020 and 2050 overarching co2 mitigation objectives set out by the european union dominate its 2010 to 2020 targets specific to the transportation arena specifically its biofuel penetration objectives and gram co2per kilometre emission caps using a dynamic recursive general equilibrium model imaclim r we demonstrate that these overarching targets do not dominate the interim transportation targets when the carbon policy triggering compliance with the mitigation objectives boils down to the theoretical least cost option of uniform carbon pricing ground transportation is confirmed as quite insensitive to high carbon prices even when such prices are applied over a long term it is tempting to conclude that pursuing the mitigation objectives specific to transportation will impose unnecessary costs however because of the second best conditions prevailing in actual economies and of the risk of lock in in carbon intensive trajectories we conclude with the urgent need for some ambitious transport specific policy design research agenda

women s labor market reactions to family disruptions shadow price varies over time it is shown that the change in a woman s labor supply is related to the deviation of the husband s actual work hours from the expected amount the estimation indicates that the largest response to the loss of husband s income occurs with a divorce or separation smaller effects are noted for widowhood husband s unexpected unemployment or health change m x easuring reactions of a married woman s labor supply to shocks to her household presents a research problem that is best addressed in a dynamic framework but recent empirical research on this topic has been conducted in a static environment in this study a dynamic model which allows for uncertainty is developed and empirically implemented with the goal of measuring the labor force response of a woman to changes in her husband s contribution to household earnings the model suggests a simple form to quantify the size of an unexpected shock to the household this shock resulting from changes in her marital status a worsening of her husband s health or her husband becoming unemployed the basic behavioral assumption is that a woman forms expectations of her husband s likely contribution to household income based on their prior experiences and she then reacts to the particular circumstances encountered in a given year in an uncertain world shocks almost always occur where a shock is defined as the difference between

does electoral competition exacerbate interethnic or interpartisan economic discrimination evidence from a field experiment in market price bargaining does political competition exacerbate economic discrimination between citizens on ethnic or partisan cleavages individuals often discriminate on group lines in ordinary economic activities especially in low income settings political competition and thus mobilization of partisan and ethnic groups waxes and wanes over the electoral cycle this study therefore investigates discrimination over the electoral cycle in a commonplace yet consequential economic activity market price bargaining by conducting field experiments on taxi fare bargaining at three points in time around ghana s 2008 election the research reveals that drivers accept lower prices from coethnics regardless of temporal proximity to the election however only at election time drivers accept lower prices from copartisans and demand higher prices from noncopartisans in sum political competition affects commonplace economic transactions between citizens on the partisan cleavage this study is the first to show evidence of interpartisan discrimination in everyday behavior and expands our knowledge of electoral cycle effects

the impact of electric power on productivity according to the historical record the increased use of energy in general and electric power in particular stands as one of the key factors in productivity growth growth accountants however find little support for this view rejecting claims that the productivity slowdown can be attributed to the lower rate of growth of the energy input in us manufacturing in this study an attempt at reconciling the historical record with the empirical facts is made specifically the commonly used factor income shares in the relevant divisia input growth index are replaced by the estimated output input elasticities the latter attribute a considerably larger role to electric power than previous studies indicated these are then used to reevaluate the sources of growth in us manufacturing

review of economic growth and energy consumption a panel cointegration analysis for eu countries abstract this paper examines the long run relationship between energy consumption and real gdp including fixed capital and total employment for 18 eu countries from 1995 to 2012 the analysis was based on the panel unit root tests panel cointegration test and fully modified ordinary least squares fmols estimator and dynamic ordinary least squares dols estimator data were analyzed in three groups all sample visegrad countries v4 and old 14 eu countries indeed the results demonstrate that economic growth and the variables energy consumption gross fixed capital are cointegrated for the whole panel of countries as well as for the two selected groups of countries furthermore the panel fmols and dols estimators reveal that the relationship between energy consumption gross fixed capital and economic growth is positive

the optimal stock of health with endogenous wages application to partial disability compensation the optimal quantity of health is examined in the framework of a model which posits that health capital will influence earning capacity in addition to the supply of labor utilizing data from the survey of disabled and nondisabled adults eight health capital variables are tested in models of hourly wages labor supply and yearly earnings the results for three of the health capital variables are then compared to their evaluation by the american medical association and by the new york state workers compensation program

electoral institutions ethnopolitical cleavages and party systems in africa s emerging democracies do electoral institutions and ethnopolitical cleavages shape the structure the fragmentation or concentration of party systems separately or jointly if they shape the structure of party systems jointly how can this joint effect be theoretically specified and empirically tested if ethnopolitical groups and associated ethnopolitical cleavages are not primordially fixed but constructed in the course of social economic and political interactions as the accumulated findings of over three decades of comparative research on ethnopolitics attest how can constructed ethnopolitical groups be specified and associated eth

energy prices and productivity growth the sharp decline in economic growth since 1973 presents a problem comparable in scientific interest and social importance to the problem of unemployment in the great depression of the 1930s conventional methods of economic analysis have been tried and have been found to be inadequate this paper outlines a new framework for understanding the slowdown in economic growth we find that the fall in u s economic growth since 1973 has been due to the dramatic decline in productivity growth within the new framework we identify higher energy prices as an important determinant of the productivity slowdown

estimating the intrahousehold incidence of illness child health and gender inequality in the allocation of time in this paper the authors develop and implement a method for estimating the effects of infant morbidity on the differential allocation of time of family members based on discrete indicators of health and activity participation commonly available in survey data and within the context of a household model in which health is determined endogenously their estimates that take into account the simultaneity of health activity associations indicate that increased levels of infant morbidity significantly exacerbate existing differentials in the accumulation of human capital across teenage boys and girls in indonesia copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

hourly earnings in the united states another look at unionization schooling sickness and unemployment using psid data this paper makes use of panel data to consider the effects of unionization schooling sickness and unemployment on individual earnings our results may be summarized as follows the unionization effect is around 15 20 this measure is consistently estimated controlling for both fixed individual attributes and serially uncorrelated measurement error sickness has little immediate impact but there is some indication that after 4 years earnings have fallen permanently by around 8 consequent on a 10 week spell of sickness a spell of unemployment on the other hand leads to a sharp fall in earnings but this effect decays rapidly leaving the possibility of a small permanent impact finally controlling for all fixed individual attributes we are unable to pin down the schooling effect with any accuracy owing to the absence of instruments that are both valid and effective within the data set

the demand for capital labor and energy in european manufacturing industry before and after the oil price shocks the price and substitution elasticities for factor inputs capital labor fuels and electricity are estimated for total manufacturing industry on the basis of a pooled crosscountry time series analysis for nine west european countries the impact of the economic disturbances in the 1970s on the price sensitivity of demand is analyzed by estimating a translog cost function for two separate periods 1960 72 and 1973 80 hicks neutral technical change is rejected for both periods the results indicate some quite significant changes in the elasticities over the two periods

schooling and economic well being the role of nonmarket effects standard estimates of the economic value of additional schooling based on earnings differences associated with differences in the level of schooling attained cover only a portion of the total effects of education that are valued by citizens we first identify a catalog of nonmarketed effects many of which have been recently studied by economists and then propose a procedure for estimating a willingness to pay value for these effects using empirical estimates of the magnitude of a selection of these effects found in the literature we calculate willingness to pay values using our proposed procedure these illustrative calculations suggest that standard estimates of the benefit of incremental schooling substantially understate the full value of such investments

labour force transitions among low wage married couples a simultaneous probability model interdependence in the labour force transitions of low income married couples is studied it utilizes a simultaneous probability model in which each person s job exit depends in part on the job transitions of their spouse estimates are based on data from the seattle denver income maintenance experiments the evidence appears to indicate that wives emulate the nonwork status of their husbands wives of exit prone husbands are themsleves more exit prone and less likely to enter employment evidence in favour of reverse dependence of husbands status on wives exits appears to be weak and imprecise

the economic consequences of debilitating illness the case of multiple sclerosis the economic consequences of debilitating illness are defined and then estimated for one such illness multiple sclerosis economic losses are defined as the consumption losses to the affected household because of illness these losses are measured as the change in earnings of all family members plus the increase in gross not out of pocket medical costs earnings models are specified and estimated and gross medical costs calculated for multiple sclerosis the average annual loss to the multiple sclerosis household is 5 336 per year in 1976 dollars the estimated aggregate decline in consumption for the year 1976 was 0 656 billion lifetime costs discounting by 0 06 total 207 200 per multiple sclerosis household and 25 50 billion for society as a whole for the current 1976 pool of multiple sclerosis patients and 30 45 billion for all future multiple sclerosis patients copyright 1987 by mit press

wage and labor supply effects of illness in cote d ivoire and ghana instrumental variable estimates for days disabled abstract sickness should make individuals less productive but there are problems in measuring this effect first how is adult morbidity measured in a household survey second how is the impact or morbidity on productivity inferred if earning is partly used to improve health self reported functional activity limitation due to illness is considered an indicator of morbidity for wage earners and self employed people to deal with both the measurement and joint determination problems an instrumental variable estimation approach is used where local food prices and health services instrument for disability days that reduce wages by at least 10 and hours by 3 or more

government expenditure and economic growth in the developed countries 1952 76 in the past decade or more the pace of economic growth has slowed considerably and the share of government expenditure in national product has increased considerably the average annual growth rate of per capita gdp for the 16 most important developed market economies was 6 3 from 1955 73 and 2 0 from 1973 79 the average share of government in gdp went from 27 in 1955 to 34 in 1970 to 43 in 1979 2 the simple correlation proves nothing but it suggests the growth of government might be one of the causes of the slowdown many economists have theorized that government production is staticly less efficient than private sector production with competitive markets see

the economic implications of public disability insurance in the united states a review of previous analyses of labor supply effects of social security disability insurance di concludes that estimates of labor supply effects and net social costs are upward biased because they ignore interactions between di and other insurances a model of optimal insurance postinjury accommodations and labor supply shows that reduction in labor supply and increase in consumption when disabled do not necessarily imply moral hazard optimal postinjury accommodations vary inversely with firm size the americans with disabilities act will reduce wages and labor supply of healthy workers particularly in small firms effects on labor supply of the disabled are ambiguous

modelling labour decisions of french agricultural households a joint model of labour decisions for farm couples is presented attention is given to operator and spouse participation decisions in the off farm labour market as well as the decision to use hired farm labour farm household labour choices which include both on farm and off farm work decisions and hired labour decisions are thus modelled as a household joint process the model is applied to a sample of french farm households empirical results illustrate the importance of spouse decisions on off farm labour participation and supply function structure they also show that operator labour and hired farm labour are complementary but wife labour and hired farm labour are substitutable

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

family labour force participation multinomial logit estimates studies of labour force participation choices are mostly aimed at explaining determinants of participation for individuals the objective of this study is the empirical estimation of the parameters of family participation decisions family participation decisions can be analysed as a choice problem of a family between a finite number of distinct alternatives the appropriate estimation procedure for a model involving choice among multiple discrete alternatives requires a statistical technique different from ordinary least squares in this study i use the multinomial logit model a logit model allows me to explain the probability that a particular participation alternative will be chosen by a family as a function of a set of independent variables it is found that economic variables such as wage rates and wealth play a significant role in affecting the probabilities of choosing a particular labour force participation alternative this study shows that an increase in the market wage for a family member not

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

the impact of disaggregated energy on productivity abstract the issue of the productivity slowdown of the 1970s and 1980s has received considerable analysis in the literature however the issue of the impact of energy on productivity is still debated this study contributes to the debate with the hope that some sight could be provided through disaggregating the factor input energy into two components a petroleum component and a non petroleum component by analysing labour productivity growth total factor productivity growth and labour intensity ratios the disaggregated energy component can be viewed as a major influence in explaining the productivity decline

disentangling the effect of arthritis on earnings a simultaneous estimate of wage rates and hours worked poor health affects both wage rates and hours of work here we develop a procedure for examining the separate impact of a specific chronic disease arthritis on wages and hours worked and then translate these results into earnings our methodology provides a consistent approach for measuring how a specific chronic disease affects total earnings as well as its component parts we find that arthritis affects wage rates and hours worked differently and the pattern of these effects differs considerably between men and women

international technological knowledge differences and economic growth comparisons usa versus west germany and sweden versus norway 1963 1988 the main interest in this paper is governed by the methodology for making evolutive growth comparisons in the international context the paper analysis differences in levels and changes of these levels of aggregate output between the above mentioned countries in terms of differences in factors input and levels of technological knowledge for the period 1963 1988 sources of economic growth in each country are also examined on an annual and average annual basis th conclusion is that technological knowledge differences between countries hold a central role in explaining output differences between them a slight overtake of the technological lead is observed in comparing sweden and norway between 1977 and 1985 when a recovery by sweden begining in 1986 is detected a certain part of the output differences between the us and west germany is explaining by the differences in technology between these two countries however capital intensity in the us is found to be almost double in 1988 and this accounts fo

an empirical model of a household s choice of activities this paper analyses how households of school age children choose to participate in the labour force volunteer work democratic assemblies and child related leisure activities contrary to previous studies the model presented in this paper treats all of these household s choice of activities involving time allocation decisions as simultaneously determined the empirical section uses qualitative data estimation techniques which permit a wide range of joint and interaction effects among the variables of the model the results confirm the importance of time opportunity cost variables as major determinants of household s choice of activities with the mother s education consituting a particularly important factor

further evidence on the economic effects of poor health this paper examines variations in current economic welfare attributable to different profiles or histories of health status over the preceding ten year period a two equation model estimated with national longitudinal survey data for four sex race groups provides convincing evidence that health problems incurred in the past adversely affect current earnings this legacy is difficult to overcome it remains even for individuals in improving health willing to devote relatively greater effort to market work a history of poor health is also shown to exact substantially different economic tolls from men and women as well as from whites and blacks

energy intake and productivity of guatemalan sugarcane cutters an empirical test of the efficiency wage hypothesis part ii abstract this paper examines additional evidence of an empirical test of the productivity consumption relation of the efficiency wage hypothesis a cross sectional analysis showed sharply diminishing productivity returns to higher levels of daily energy intake of guatemalan sugarcane cutters no positive and consistent energy supplementation effect on the daily supply of work units could be demonstrated in a time series analysis energy supplementation did not have a delayed impact on worker productivity it is concluded that increased energy availability may not necessarily result in increased productivity of rural workers who are moderately energy deficient

causes of the current stagflation since 1975 labour slack has been unusually high in the oecd countries and yet inflation has not diminished the less favourable mix of unemployment and rate of change of inflation which we call stagflation is explained by a fall in the feasible rate of growth of real wages unmatched by a reduction in the constant term in phillips curve to investigate this mechanism conventional wage and price equations are estimated for 19 countries and then used for simulation stagflation has been caused in roughly equal amounts by rising relative import prices and by the fall in the rate of productivity growth in the basic model the phillips curve is assumed not to adapt to falls in feasible real wage growth but in a final section an adaptive wage equation is estimated which confirms that the process of adaptation is slow

work and the accommodation of chronic illness a re examination of the health labour supply relationship this study uses a data set of over 14000 households from the state of new jersey in the usa to estimate the impact of specific chronic health conditions on the probability of employment and finds wide variation of employment impacts across chronic conditions additionally the elasticity of the employment response is generally greater for women and lower skilled workers most notable is the role of comorbidity individuals with multiple conditions have markedly lower probability of employment and chronic illness explains virtually all of the large gap in employment probability for those who have multiple conditions this is shown using a summary index of disease status that correlates closely with employment rates across age groups in the aggregate chronic disease striking in adulthood explains about 10 of the total non employment in the new jersey among those aged 35 74 finally cross sectional evidence gives little support for health as a primary determinant of the aggregate age employment profile

husband s health and wife s labor supply this paper examines the labor supply response of the wife to deterioration in the husband s health unlike past cross sectional studies responses over time are directly examined through the use of longitudinal data the empirical results suggest that the magnitude and direction of the response depend crucially on the attractiveness of transfers which the family may qualify for when the husband s health deteriorates when no transfers are available the wife increases her market work in order to replace the lost earnings of the husband however as transfers become more attractive the wife begins to reduce her labor supply enabling her to spend more time at home caring for her husband

health nutrition and economic development the relationship between health and economic development is explored focusing on nutrition based health indicators the spotlight is placed on the inter related feedbacks between the influence of health on productivity on one hand and the influence of income on health status on the other disentangling causality in these relationships has preoccupied much of the literature we evaluate different empirical strategies that have been adopted and assess the results there is now a body of evidence based on careful empirical studies that demonstrates a causal relationship between health and labor productivity there is also evidence that at least among the very poor additional income is spent on improved nutrition there are two issues that have received little attention although we argue they are likely to be very important first measurement of health is discussed in detail evidence is presented on how taking into account differences in the extent of measurement error is critical for interpreting the impact of health on wages the same theme emerges in studies of the effect of income on health specifically calorie intake the key role of non linearities in these relationships is highlighted and we demonstrate that a good deal of the variation in estimates of income elasticities of demand for calories can be ascribed to the role of measurement and functional form authors

health as an unobservable a mimic model of demand for health care abstract this paper develops a model to analyze the demand for health care it differs from current practice in that 1 it deals explicitly with the complex relation between income health health insurance and the demand for health care and 2 health is treated as an unobservable variable we present the maximum likelihood estimates of an eleven equation simultaneous multiple indicator multiple causes mimic model containing two simultaneously determined unobservables and in total nine indicators data used stem from a health care survey among 8000 households in the netherlands the results show among other things that health and permanent income have mutual positive impacts both age and education have important direct and indirect via permanent income effects on health the estimated impact of the availability of health care on individual demand confirms similar results based on aggregated data

health status and health dynamics in an empirical model of expected longevity expected longevity is an important factor influencing older individuals decisions such as consumption savings purchase of life insurance and annuities claiming of social security benefits and labor supply it has also been shown to be a good predictor of actual longevity which in turn is highly correlated with health status a relatively new literature on health investments under uncertainty which builds upon the seminal work by grossman grossman m 1972 on the concept of health capital and demand for health journal of political economy 80 223 255 has directly linked longevity with characteristics behaviors and decisions by utility maximizing agents our empirical model can be understood within that theoretical framework as estimating a production function of longevity using longitudinal data from the health and retirement study we directly incorporate health dynamics in explaining the variation in expected longevities and compare two alternative measures of health dynamics the self reported health change and the computed health change based on self reports of health status in 38 of the reports in our sample computed health changes are inconsistent with the direct report on health changes over time and another 15 of the sample can suffer from information losses if computed changes are used to assess changes in actual health these potentially serious problems raise doubts regarding the use and interpretation of the computed health changes and even the lagged measures of self reported health as controls for health dynamics in a variety of empirical settings our empirical results controlling for both subjective and objective measures of health status and unobserved heterogeneity in reporting suggest that self reported health changes are a preferred measure of health dynamics

work and health after retirement a competing risks model with semiparametric unobserved heterogeneity competing risks models recognize that there may be more than one exit from a given state but they make the strong assumption that there is no correlation between unobserved heterogeneity components in each state here a competing risks model that uses a semiparametric method of estimation and controls for the correlation between unobserved heterogeneity components in each state is compared with a traditional competing risks model of exit from retirement the unobservable heterogeneity components of the competing risks are insignificantly positively correlated and the effects of policy relevant variables are changed somewhat copyright 1989 by mit press

disability gender and the labour market in wales jones m k latreille p l and sloane p j 2006 disability gender and the labour market in wales regional studies 40 823 845 wales exhibits high rates of disability and inactivity and a higher incidence of mental health problems than other parts of britain using data from the welsh local labour force survey 2001 the results indicate that the low participation rate of the disabled in wales is partly attributable to their having fewer qualifications marginal effects suggest education could be a potent remedy for improving their labour market status in terms of the pay differential between disabled and non disabled individuals it would appear that disabled women in wales suffer disproportionately to disabled men only in the case of women is there evidence consistent with the presence of discrimination but this estimate is relatively small jones m k latreille p l et sloane p j 2006 l invalidite le genre et le marche du travail au pays de galles regional studies 40 823 845 le pa

the role of economic incentives in teenage nonmarital childbearing choices abstract in this paper we explore whether behaviors of youths that are likely to result in a teen nonmarital birth event are influenced by their expectations of the net economic benefits or costs associated with the occurrence of such a birth we posit and find that an increase in the perceived costs associated with the occurrence of a nonmarital birth would lead to a reduction in these risky behaviors and to a lower probability of a nonmarital birth event we represent these economic incentives by the income expectations of young women conditional on either giving birth as an unmarried teen or forgoing childbearing while unmarried and an adolescent we also measure the effects of an extensive list of other factors including the characteristics of the girl s family and its choices the social and economic environment in which she lives including policy related factors such as expenditures by states on family planning programs and the generosity of aid to families with dependent children and her own prior choices

modeling production for general equilibrium analysis the purpose of this paper is to present econometric models of producer behavior suitable for incorporation into a general equilibrium model implementation of these models requires a time series of inter industry transactions tables second implementation requires methods for estimation of parameters in systems of nonlinear simultaneous equations finally the economic theory of producer behavior implies equality and inequality restrictions on the parameters that must be incorporated into the estimation we discuss an empirical application to modeling producer behavior in thirty six industrial sectors of the u s economy

income productivity in china on the role of health this study provides empirical evidence regarding the income productivity of health human capital in china we appeal to concepts from human capital theory to support a basic model that treats health as a form of human capital in the income production process our model examines the economic return at the household level from the health of its individual members we estimate this with a longitudinal sample drawn from the china health and nutrition survey chns allowing us to exploit within variation in health and income to address possible unobservables biasing estimates of the impact of health on income in the simple cross sectional setting household income is strongly influenced by the health of its members particularly in rural areas these findings could have important implications for health and economic policy making aimed at reducing the long standing urban rural economic gap and more comprehensively insuring the rural population against health and economic risk

party system competition and private sector development in africa abstractdemocratic transitions by many african countries have generated much analysis of the organisational features of political parties or their role in voter mobilisation during elections yet scholars have largely overlooked how parties negotiate economic policymaking or interact with the private sector in countries that are incipient democracies and emerging markets this article argues that the stability or fragmentation of the party system affects patterns of private sector development and shapes linkages between the state business and labour it compares mozambique and zambia to demonstrate how variations in party system characteristics influence the relationship between economic and political interests

from formlessness to structure the institutionalization of competitive party systems in africa giovanni sartori once described african party systems as formless our contribution challenges this view in an era of resurgent multipartism that swept through the subcontinent in the early 1990s and continues until today the article brings together contemporary research on african party systems with the wider disciplinary literature on party system institutionalization using a data set including all continuous election sequences in africa from 1950 to 2008 we find that africa has some of the most volatile party systems ever recorded and yet tremendous diversity across regimes we test the relative impact of political institutions economic performance the history of party system development and social cleavage structure on party system institutionalization in africa we find that its party systems have been shaped by a set of factors unique to the subcontinent but some of the general global patterns of party system development hold true in africa as well

corporate social responsibility in the banking industry motives and financial performance abstract the current study investigates the association between corporate social responsibility csr and financial performance fp and discusses the driving motives of banks to engage in csr three motives namely strategic choices altruism and greenwashing suggest that the relationship between csr and fp is positive non negative and non existent respectively we obtained our sample which covered 2003 2009 from the ethical investment research service eiris databank and bankscope database the data consists of 162 banks in 22 countries we then classified the banks into four types based on their degree of engagement in csr this study proposes the use of an extended version of the heckman two step regression in which the first step adopts a multinomial logit model and the second step estimates the performance equation with the inverse mills ratio generated by the first step the empirical results show that csr positively associates with fp in terms of return on assets return on equity net interest income and non interest income in contrast csr negatively associates with non performing loans hence strategic choice is the primary motive of banks to engage in csr

the impact of farmers health and nutritional status on their productivity and efficiency evidence from ethiopia this article focuses on the link between agricultural productivity and health and nutrition status of peasants in ethiopia the data come from the first round of the ethiopian rural household survey conducted in 1994 the sites selected were those in which farmers practice ox plow cultivation of cereals a stochastic frontier approach was adopted for the agricultural production the findings of the study show that the distance to the source of water as well as nutrition and morbidity status affect agricultural productivity the market wage rate is also very responsive to the weight for height as well as the body mass index and height in a context where separability between consumption and production decisions of the household is rejected elasticities of labor productivity with respect to nutritional status are noted to be strong and similar in technology estimates and wage equations moreover returns to investment in nutrition are clearly high in the ethiopian context overall the results indicate substantial loss in output due to technical inefficiency even after accounting for the health and nutrition of workers

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

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

health and wages panel data estimates considering selection and endogeneity this paper complements previous studies on the effects of health on wages by addressing the problems of unobserved heterogeneity sample selection and endogeneity in one comprehensive framework using data from the german socio economic panel gsoep we find the health variable to suffer from measurement error and a number of tests provide evidence that selection corrections are necessary good health leads to higher wages for men while there appears to be no significant effect for women contingent on the method of estimation healthy males are estimated to earn between 1 3 and 7 8 more than those in poor health

productivity and cost gaps in manufacturing industries in u s japan and germany abstract the objective of this paper is to measure and explain the development of differences in productivity for five manufacturing industries of the u s japan and germany changes in total factor productivities and differences in technologies and the sources of those changes will be analyzed we extend the framework developed by jorgenson and nishimizu 1978 to the dual cost approach to reflect the efficiency aspect of productivity gaps in terms of cost disadvantages we employ translog cost functions for a description of productivity and cost efficiency gaps and for an econometric analysis of sources of catching up processes
