corporate environmental responsiveness in india lessons from a developing country abstract we examine corporate environmental responsiveness in business organizations in india based on theoretically informed case analysis we operationalize corporate environmental responsiveness as a two order construct we find that level one the lower level responsiveness is driven by pressures arising out of powerful supply chain customers and institutional pressures resulting from internationalization the drivers for organizations at level two the higher level responsiveness are associated with organizational identities and cultures rooted in a long history of social responsiveness

the economics of iron deficiency abstract this paper examines the evidence for a causal relationship between iron deficiency and a variety of functional consequences with economic implications motor and mental impairment in children and low work productivity in adults to the extent that we can be confident that iron deficiency does cause a consequence with economic implications this effect is quantified in economic terms illustrative calculations for 10 developing countries suggest that the median value of annual physical productivity losses due to iron deficiency is around 2 32 per capita or 0 57 of gdp median total losses physical and cognitive combined are 16 78 per capita 4 05 of gdp using a cost of 1 33 per case of anemia prevented from one of the few effectiveness studies of national fortification allows us to calculate the benefit cost ratio for long term iron fortification programs the median value is 6 1 for the 10 countries examined and rises to 36 1 including the discounted future benefits attributable to cognitive improvements this paper improves on previous work by including a much more thorough survey of the quantitative magnitudes involved and by incorporating effects of iron deficiency on cognition however more research is needed to verify the accuracy of the assumptions needed for this type of analysis

the use of quantile regressions in estimating gender wage differentials a case study of the philippines quantile regressions are used to analyse the size components and nature of the gender earnings differentials as well as the returns to education by gender in the philippines over the entire conditional distribution of earnings using data from the 1999 apis survey this approach allows more focused conclusions about the nature of gender earnings differentials incorporating the quantile regression approach to the oaxaca blinder decomposition allows the localization of gender discrimination to particular quantiles of the earnings distribution and permits more targeted policy intervention

the effect of family background on children s level of schooling attainment in spain this paper provides microeconomic estimates of the role played by family background in determining children s level of schooling attainment in spain we use an ordered logit model to explore the effects of family background and other supply factors on the probability of various educational outcomes our estimates are based on household data obtained from the ecvt living and working conditions survey ministerio de economia y hacienda 1985 a spanish nation wide household survey conducted at the end of 1985 in general and given the spanish capital constraints parental income social class and family size explain children s level of schooling these results are consistent with those of the literature that focuses on the role of family background in determining schooling attainment

affirmative action in higher education how do admission and financial aid rules affect future earnings this paper addresses how changing the admission and financial aid rules at colleges affects future earnings i estimate a structural model of the following decisions by individuals where to submit applications which school to attend and what field to study the model also includes decisions by schools as to which students to accept and how much financial aid to offer simulating how black educational choices would change were they to face the white admission and aid rules shows that race based advantages had little effect on earnings however removing race based advantages does affect black educational outcomes in particular removing advantages in admissions substantially decreases the number of black students at top tier schools while removing advantages in financial aid causes a decrease in the number of blacks who attend college

the determinants of an environmentally responsive firm an empirical approach abstract our empirical results indicate that a firm s formulation of an environmental plan is positively influenced by customer pressure shareholder pressure government regulatory pressure and neighborhood and community group pressure but negatively influenced by other lobby group pressure sources and a firm s sales to asset ratio firms which view environmental issues as important in the next 5 years are also more likely to have a plan relative to the manufacturing sector firms in the natural resource sector are more likely to formulate environmental plans while firms in the service sector are less likely to have plans our results provide insight into how firms react to environmental issues they also offer policymakers a list of determinants which can be used either as an alternative or complement to environmental regulation

are those paid more really more productive the case of experience this study uses computerized personnel microdata on the white male managerial and professional employees at a major u s corporation to address the following question can the additional earnings which are associated with more labor market experience at a point in time really be explained by higher productivity at the same point in time our answer to this question based on both cross sectional and longitudinal information is that performance plays a substantially smaller role in explaining cross sectional experience earnings differentials and earnings growth than is claimed by those who have adopted the human capital explanation of the experience earnings profile this response depends critically on our assumption that the performance ratings which supervisors give to their white male managerial and professional subordinates adequately reflect the subordinates relative productivity in the year of assessment we present a great deal of evidence which strongly supports this assumption

on decomposing the wage gap a critical comment on blinder s method many studies have found that the impact of schooling on earnings is greater for females than for males despite the fact that females tend to earn less both absolutely and controlling for personal characteristics this study investigates possible

college selectivity and earnings this article shows that college performance and selectivity have significant effects on earnings it suggests that work that does not include college performance overstates the effect of college se

a positive theory of environmental quality regulation this paper demonstrates that environmental quality regulation may enhance producer wealth while simultaneously reducing an externality problem by restricting access to common property regulation not only corrects a resource misallocation but it creates a scarcity rent as well in the recent history of environmental quality the common access problem has been addressed by federal and state agencies through a standards based approach rather than through the enforcement of tradable property rights as a consequence rents from the right to use these assets have accrued to producers the data are convincing that there is a strong interplay between producers consumers and the victims of pollution each party has some influence on the outcome and one sided analysis neglects many important aspects of regulation environmental quality regulation is complicated but many of the observed perplexities are consistent with a rent seeking self interest theory of government 46 references 1 figure 7 tables

toward a theoretical model of voluntary overcompliance abstract we explain why some firms voluntarily overcomply with environmental regulation in our model all consumers value environmental quality but differ in their willingness to pay which depends on their income levels publicly available information on environmental performance of firms enables consumers to identify clean firms firms participate in a two stage duopoly game where they first choose their levels of cleaning technology and next engage in price competition the market gets segmented by income levels a minimum standard binding on the dirty firm has the effect of improving the performance of the cleaner firm a subsidy obtains the same competitive outcome

bootstrapping statistical inferences of decomposition methods for gender earnings differentials applying the standard bootstrapping technique with corrections for heteroskedasticity for a sample of the 1997 urban household survey in china the present article attempts to test 1 whether the commonly used decomposition methods for gender earnings differentials give significantly different results and 2 whether the explained component is significantly different from the unexplained component which is commonly referred to as discrimination within each decomposition method based on a national data set the empirical results indicated some significant differences in both tests the implication of the results is that the proposed bootstrapping technique can be regarded as a guideline on applying which approach to decompose gender earnings differentials among different methods without losing important information and on evaluating the relative importance of the decomposition components for any chosen method

detecting and removing discrimination under equal opportunities policies abstract this paper surveys part of the recent voluminous literature on the economics of discrimination focusing on two key questions first how should discrimination be measured and can in fact unambiguous estimates be derived as the basis for detecting where discrimination is present and setting in train measures to eliminate it second to what extent has the implementation of equal opportunities legislation improved the relative standing of women and minority workers in the labour force this section includes a discussion of the likely effects of recent changes in the law such as the equal value amendment in the uk or the introduction of comparable worth in the usa the survey concludes that our ability to detect discrimination at all precisely is still rudimentary and consequently policy measures are likely to be inefficient for this reason

a bayesian approach to decomposing wage differentials abstract we decompose wage differentials using a bayesian monte carlo markov chain method this method makes it easy to obtain the posterior distributions of the characteristics and coefficients effects used to test the significance of the two effects

intertemporal market effect on gender earnings differentials lawyers in canada 1970 80 the conventional methodology for decomposition of cross sectional earnings differentials is extended to include a market effect on intertemporal changes in earnings and to analyse the changes in gender differentials over time the integrated cross sectional and intertemporal methodology is illustrated by a decomposition of the change in the earnings differential that occurred during the 1970s between male and female lawyers in canada an unprecedented rate of growth in the supply of lawyers during the 1970s in canada was associated with changes in the gender earnings differential in the legal profession this rapid supply growth had an almost negligible net impact on female earnings but a negative impact of 15 on the male earnings this explains the narrowing of the earnings differential by almost 30 over the decade although three fifths of the gender differential in 1970 and half of the differential in 1980 were attributable to the differences in the characteristics of the two groups these chang

determinants of environmental investments testing the structural model abstract the main purpose of this study is to provide the needed additional quantitative evidence regarding the introduction of environmental technologies and to increase the possibility for generalization and thus policy application of conclusions to achieve that purpose a conceptual model is developed and then tested on a large database of firms from various industries with the use of structural equation modeling the results show that policy measures past environmental investments the importance of environmental technologies for customers and the firm performance have a positive effect on environmental investments furthermore the results show that policy measures are a second order three factor construct

the costs of water pollution regulation in the pulp and paper industry this paper studies plant level data on actual and permitted levels of water pollution emissions for the pulp and paper industry there is widespread and substantial overcompliance with the relevant regulations aggregate bod emissions in 1992 were only 50 of the amount allowed overcompliance appears to imply a zero marginal abatement cost and its prevalence therefore has the potential to substantially change the debate over the costs of regulation we show instead that plants incurred substantial costs to overcomply marginal abatement costs were roughly 13 000 ton in 1992 we discuss possible explanations for costly overcompliance and their implications for estimation

why do part time workers earn less the role of worker and job skills part time workers receive considerably lower hourly earnings than do full time workers using current population survey earnings files for september 1995 through december 2002 the author finds that measurable worker and job characteristics including occupational skill requirements account for much of the part time penalty longitudinal analysis of the data indicates that much of the remaining gap reflects worker heterogeneity evidenced by small wage gains and losses among workers switching between part time and full time jobs the lower skills of part time than full time workers result primarily from limited work experience and accumulation of human capital little evidence can be found of a large wage gap between part time and full time women a part time wage penalty is found for men but men account for less than one third of total part time employment

willingness to pay for environmental practices implications for eco labeling consumer survey data collected in former west and east berlin after the unification of germany are used to address the issue of willingness to pay wtp for foods produced with techniques consistent with environmental stewardship results show differences in the wtp between residents of the two former german states attributed to area of residence residents of eastern city districts were generally less willing to pay a premium for foods produced with environmental friendly methods which suggests that marketing of such foods will be more successful in western districts unless educational efforts can be used to bridge the gap in the stated wtp

life after debt postgraduation consequences of federal student loans we estimate the causal effect of student loans on postgraduation labor market outcomes exploiting a kink in the formula determining eligibility for need based student loans using a representative sample of students graduating with a bachelor s degree in 1993 we find that student debt has nonnegative effects on earnings this result holds with differing levels of statistical significance across a battery of different empirical designs 1 ordinary least squares 2 partially linear and 3 regression kink we find similar results for the 2008 graduating cohort jel i22 i26 j32 j33

technology and firm size wage differentials in colombia mexico and taiwan china in many economies studies have found large wage differentials not accounted for by workforce characteristics collective bargaining or market power researchers attribute these differentials to either unobserved worker quality or pay incentives designed to elicit worker effort this article finds empirical support for an alternative explanation these wage differentials result from firms technology generating activities using firm level data from colombia mexico and taiwan china the article compares the effects of research and development worker training and exports by employers on the wages of skilled and unskilled workers the results suggest that technology investments lead to large wage premiums for skilled workers but not for unskilled workers these wage premiums are primarily the result of investments in research and development and in training while exporting is relatively less important except in colombia

public inputs and child schooling in brazil household data from a one percent sample of the 1970 brazilian census are used to analyze the effect of public inputs i e the supply of schooling on children s school attainment in brazil the household data are combined with measures of school availability and quality derived directly from the same census data the measures are based on the number and education of schoolteachers in each of 169 different areas of the country elasticities of demand with respect to these public inputs are estimated these elasticities are high in both rural and urban areas in urban areas the positive effect of public inputs is greater for children from households with poorer and less educated parents in rural areas the positive effect of public inputs is greater if anything for children from households that are relatively better off at least compared to other rural households

gender differences in the intergenerational transmission of education in spain the role of parents employment status and education this article examines the influence of parents education and employment status on the attained educational level of their children with special reference to gender differences our study analysed

a model of university admission and tuition policy this paper contains an analysis of the admission and tuition policy of a university that maximizes its utility which depends on the aggregate value of its students and the endowment left for the future higher academic ability increases a student s value to the university while higher tuition decreases the likelihood that an admitted application enrolls the effects of the endowment the number of applicants etc are studied both when applications differ in their academic ability only and when applicants also differ in some other aspect such as parental income sex or ethnic origin the effects of affirmative action are considered copyright 1990 by the editors of the scandinavian journal of economics

time allocation decisions associated with job market preparation undergraduate perceptions versus market realities a survey of agribusiness firms identifies characteristics associated with above average starting salary offers in the allied fields of agribusiness agricultural economics business and economics a complementary survey is made of students at texas a m university and university of georgia results show that firms value work experience and leadership experience more than students do whereas students value raising grade point average and interview preparation more than do firms students seeking a firm s maximum starting salary offer will need to enhance academic performance with substantial work experience and leadership experience copyright 2002 oxford university press

returns to education a further international update and implications this paper updates evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 the new cross country evidence confirms and reinforces earlier patterns namely that returns are highest for primary education the general curricula the education of women and countries with the lowest per capita income the findings have important implications for directing future investment in education which for efficiency and equity purposes should concentrate on these priority areas

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

wages employment structure and employer size wage premia their relationship to advanced technology usage at us manufacturing establishments a common theme in the labour econiomics literature is that use of advanced technology in production requires a skilled and educated workforce using a new survey of production processes at us manufacturing plants we ask whether plants that employ advanced technology require a skilled workforce we find that plants that use the most advanced technology pay the highest wages and employ the greatest fraction of non production workers who are generally regarded as more skilled than production workers the inclusion in standard wage regressions of variables that indicate the use of advanced technology reduces the size wage premia by as much as 60 for some size categories

union certification success under voting versus card check procedures evidence from british columbia 1978 1998 the author estimates the impact of compulsory election laws on certification success using data on over 6 500 private sector certifications from british columbia over the years 1978 98 a unique quasi experimental design is used by exploiting two changes in the union recognition law first in 1984 the introduction of mandatory elections and second in 1993 the repeal of elections and their replacement by the original card check procedure the author also estimates the effectiveness of management opposition tactics across union recognition regimes success rates declined by an average of 19 percentage points during the voting regime and then increased by about the same amount when card checks were re instituted the results indicate that the mandatory election law can account for virtually the entire decline in addition the findings suggest that management opposition was twice as effective under elections as under card checks

match bias from earnings imputation in the current population survey the case of imperfect matching this article examines match bias arising from earnings imputation wage equation parameters are estimated from mixed samples of workers reporting and not reporting earnings the latter assigned earnings of donors regressions including attributes not used as imputation match criteria e g union are severely biased match bias also arises with attributes used as match criteria but matched imperfectly imperfect matching on schooling age flattens earnings profiles within education age groups and creates jumps across groups assuming conditional missing at random a general analytic expression correcting match bias is derived and compared to alternatives reweighting a respondent only sample proves an attractive approach

the effect of sibling sex composition on women s education and earnings this paper documents the impact of siblings on the education of men and women born in the united states between 1920 and 1965 we examine the effect of the number and sex composition of a boy or girl s siblings on that child s educational attainment we find that throughout the century women s educational choices have been systematically affected by the sex composition of her siblings and that men s choices have not women raised only with brothers have received on average significantly more education than women raised with any sisters controlling for household size since sibling sex composition affects women s educational attainment and plausibly may be unrelated to other determinants of earnings it may provide a useful instrument for education in earnings functions for women our results suggest that standard estimates significantly underestimate the return to schooling for women

human capital and information this paper examines the issue of the establishment size wage effect it analyzes a cross section for the year 1979 with information on 607 individuals and the 60 private sector establishments where they work it discusses four theories of the establishment size wage effect and uses empirical proxies to test them it shows that when a dummy variable on computer access in the establishment is introduced as a regressor the establishment size variable is an insignificant regressor this result and other evidence supports the contention that the establishment size coefficient captures the effect of unobserved human capital accumulation

evolution of the gender earnings gap among canadian university graduates this paper reports the results of an empirical analysis of the gender earnings gap among recent canadian bachelor s level university graduates the overall gap as of two years leaving university narrowed significantly across successive cohorts of graduates but widened significantly from two to five years out for all groups differences in the explanatory variables explain account for between 40 and essentially the entire gap across the different periods this portion rising from two to five years out and across cohorts by the final group all of the gap is thus explained at the two year point in time and most of it is explained at the five year mark meaning that labour market returns measured in this manner are largely gender neutral for the last group of graduates hours of work is the single most important influence while past work experience job characteristics family status and province of residence and language have smaller and more mixed effects

corporate social responsibility sustainable water use freshwater scarcity is no longer limited to sub saharan developing countries also in western society access to unlimited amounts of freshwater is not assured at all times it has been argued and laid down in many national legal systems that access to freshwater is a basic human right what if corporate freshwater use threatens to interfere with this human right the main focus of the article is to explore the role of today s companies in relation to freshwater a number of tools have been developed to attend to the necessity to reduce corporate use of freshwater the article discusses specialised water reporting instruments such as the 2007 global water tool and the water footprint calculation method in addition attention is paid to a ceres report 2010 revealing that the majority of the 100 world s leading companies in water intensive industries still has weak management and disclosures of water related risks and opportunities to obtain concrete information about corporate water strategies and practices an explorative analysis was conducted on 20 dutch multinational companies the article highlights various innovative practices in sum it is demonstrated that companies are expected to bear responsibility for their impact on water resources in particular when it influences public access to water in areas with freshwater scarcity and or weak government notwithstanding the critical conclusions of the ceres report it is interesting to see an evolution in corporate research concerning sustainable water use and the development of greener products and greener ways of production

the design of optimal education policies this paper studies the education policy chosen by a utilitarian government in the model households differ in their income and in their children s ability income is observed by the government but ability is private information households can use private education but cannot borrow to finance it the government can finance education with income tax but at the cost of blunting the individuals incentive to exert labour market effort the optimal education policy we derive is elitist it increases the spread between the educational achievement of the bright and the less bright individuals compared to private provision it is also such that the education received by less bright individuals depends positively on their parental income finally the optimal education policy is input regressive in the sense of arrow 1971 quarterly journal of economics 38 175 208 households with higher income and brighter children contribute less in tuition fees towards the cost of the education system than households with lower income and less bright children

test scores educational opportunities and individual choice abstract a model combining student preferences for college with university admissions decisions is estimated to provide information on the role of test scores in the determination of post secondary educational opportunities in the u s in contrast to implications of much of the recent criticism of tests and their use we find that scholastic aptitude test scores are more strongly related to student application and choice of college quality than to college admissions decisions in addition although there is a substantial correlation between test scores and high school performance we find that both post secondary school preferences and ultimate opportunities are related as much to performance in high school as to test scores themselves although sat scores certainly exclude some persons from schools our findings indicate that they do not represent an overriding constraint on the college opportunities of high school graduates

wage determination of registered nurses in proprietary and nonprofit nursing homes this study explores why registered nurses employed in nonprofit nursing homes earn higher wages than those employed in proprietary facilities previous studies have explained this finding in a property rights context where higher wages were posited to result from the weaker incentives for cost minimization accompanying nonprofit status this paper tests an alternative explanation of sectoral wage differences which is predicated on the reason for the coexistence offor profit and nonprofit firms in a given industry informational constraints concerning the quality of care are posited to cause the long term health care market to fail to provide care at the upper levels of a quality of care continuum nonprofits are viewed as a response to this form of market failure acting to fulfill customers demand for higher quality and higher cost long term care with attendant demand for higher quality nurses than in for profit homes both the observed sectoral pattern in selectivity and wage decompositions based on selectivity corrected wage regressions call into question the property right explanation yet are consistent with an asymmetric information explanation

epa s voluntary 33 50 program impact on toxic releases and economic performance of firms abstract this paper examines the motivations for participation in the voluntary 33 50 program and the program s impact on the toxic releases and economic performance of firms in the u s chemical industry it demonstrates that the benefits due to public recognition and the potentially avoided costs of liabilities and compliance under mandatory environmental regulations provide strong incentives for participation after controlling for sample selection bias and the impact of other firm specific characteristics this paper shows that program participation led to a statistically significant decline in toxic releases over the period 1991 93 the program also had a statistically significant negative impact on the current return on investment of firms but its impact on the expected long run profitability of firms was positive and statistically significant

working part time by choice or by constraint the selection of workers into part time jobs and the wages they earn are analysed using the 1989 labour market activity survey we focus on the distinction between voluntary and involuntary part time workers since involuntary part time workers earn substantially lower wages than other workers we find that the selection of individuals into involuntary part time work is more closely tied to job characteristics than personal or human capital characteristics the lower wage earned by involuntary part time workers is largely due to differences in returns and selection effects rather than differences in endowments

different firm size effects on wages for supervisors and workers abstract we find that i the plant size effect for supervisors is at least double that of non supervisors ii the difference is statistically significant and iii the firm size effect for supervisors is not explained by differential returns on standard variables

why japanese firms choose to certify a study of managerial responses to environmental issues abstract this paper examines empirically the determinants that led large japanese manufacturers to 1 incorporate environmental goals in their decisions 2 obtain environmental certification iso 14001 and 3 become early adopters of environmental certification we estimate two sets of models 1 models based on a profit maximization assumption and 2 models which incorporate utility maximization arguments recognizing that managers values attitudes and beliefs may also influence firms decisions the empirical analysis suggests that while the costs and benefits of voluntary actions to enhance or protect the environment and the capacity to act are significant determinants of voluntary environmental commitment so are the environmental values beliefs and attitudes of managers

does it pay to attend an elite private college cross cohort evidence on the effects of college type on earnings although a substantial and rising labor market premium is associated with college attendance in general little is known about how this premium varies across institutions of different types and across time in this paper we explicitly model high school students choice of college type characterized by selectivity and control based on individual and family characteristics including ability and parental economic status and an estimate of the net costs of attendance we estimate selectivity corrected outcome equations using data from both the national longitudinal study of the high school class of 1972 and high school and beyond which permit us to determine the effects of college quality on wages and earnings and how this effect varies across time even after controlling for selection effects strong evidence emerges of a significant economic return to attending an elite private institution and some evidence suggests this premium has increased over time

earnings schooling ability and cognitive skills conventional estimates now available for a large number of countries generally indicate that the social returns to education are positive large and competitive with returns to investment in physical capital that such estimates are good guides for public resource allocation has however been questioned the heart of the problem lies in the interpretation of the positive relationship between the education and the earnings of workers whether as the conventional estimates assume the coefficient of the education variable in the earnings function measures the effect on the productivity of workers of human capital acquired in school it has been hypothesized that education in part or instead represents screening for native ability and motivation or credentialism and that as a consequence conventional measures of the social benefit of education are substantially upward biased 2 in this paper we attempt to distinguish the influence on earnings of cognitive achievement native ability and years of education as a means of adjudicating the human capital screening and credentialist hypotheses our econometric analysis is based on two rigorously comparable micro data sets from kenya and tanzania generated by surveys of the urban wage labor force specifically for this study these data sets contain the usual variables found in earnings function estimates of the benefits of schooling individual earnings years of education and years of employment experience in addition they contain two variables measures of the worker s cognitive skills and of his or her reasoning ability not previously found in studies of developing countries and only rarely found in studies of the education earnings relationship in developed countries 3 with these variables we can estimate the direct effects on earnings of cognitive skills ability and years of schooling by using them to estimate educational production functions and educational attainment functions and linking these functions with the earnings function in a recursive framework we can also assess the various indirect effects on earnings of ability and years of schooling having data sets from two countries very similar with respect to size resource endowments structure of production and employment and level of development means that not only can we subject our results to the usual statistical tests but we can also assess their replicability both kenya and tanzania have nearly achieved the objective of universal primary education while university enrollments remain at less than 1 percent of the relevant age group the important policy issues re boissiere development research department the world bank 1818 h street washington d c 20433 knight institute of economics and statistics oxford university sabot williams college williamstown ma 01267 we are grateful to the educational testing service of princeton for the design of tests used in this study and to j armitage j behrman j hausman d hendry d jamison and an anonymous referee for their insights and advice helpful comments were also received from participants in seminars at oxford and yale universities the views presented here are our own they should not be interpreted as reflecting those of the world bank george psacharopoulos 1973 1981 contains a listing of 44 countries in which rate of return studies had been conducted and of the estimates obtained 2for instance kenneth arrow 1973 mark blaug 1976 samuel bowles and herbert gintis 1976 john riley 1979 michael spence 1976 and lester thurow 1975 3for attempts to control for ability and or for cognitive achievement in studies for the united states see jere behrman et al 1980 gary chamberlain and zvi griliches 1977 griliches and william mason 1972 michael olneck 1977 paul taubman and terence wales 1974 taubman 1975 and david wise 1975 see also the survey articles by griliches 1977 1979 in most instances the data refer to special subgroups in the population and clear distinction cannot be made between natural ability and cognitive skills acquired in school

determinants of proactive environmental management practices in indian firms an empirical study abstract the present study aims to empirically determine the primary factors that have a major influence on adoption of environmental management practices in indian firms for this purpose a theoretical framework has been proposed based on previous studies and a pilot survey that provides broad and specific variables that might have an impact of these practices this impact has been investigated by conducting factor analysis and stepwise regression analysis in order to collect the primary data a questionnaire has been designed for which 104 valid responses 8 5 response rate have been obtained the study reveals that internal holder ship and employees and market commercial buyers and suppliers of goods and services pressures are the significant drivers who govern the adoption of proactive environmental management practices however the external pressures from regulatory and societal stakeholders were not found to be important in the indian context the analysis further showed that firm s characteristic also play a significant role in defining the positive behavior of firms as large firms are more proactively engaged in environmental management initiatives moreover firms in the manufacturing chemical and agriculture sector are likely to have more comprehensive environmental management practices compared to the service sector

the impact of unionization on male female earnings differences in canada the impact of unionization on male female earnings differences in canada is analyzed using data spanning 1981 to 1988 a period in which the male female unionization gap narrowed considerably gender differences in union density union wages and nonunion wages are decomposed into characteristics related and discriminatory components we find that the drop in the gender unionization gap prevented an increase of 7 percent in the overall wage differential between men and women also male female earnings differences in the nonunion sector make a substantially larger contribution to the gender earnings gap than do those in the union sector

compensating differentials for shift work a model analyzing the choice of shift is developed and estimated using data from two supplements to the current population survey the findings show a positive wage premium for shift work that varies with personal characteristics and there is strong evidence showing the importance of self selection as workers with low potential daytime earnings are more likely to choose night work and supplement their earnings the findings demonstrate that cross section estimates of wage premiums for union membership and firm size are biased upward because they pick up some of the compensating differential for shift work

parental childcare and children s educational attainment evidence from china this paper examines the determinants of child educational attainment in addition to those examined in previous studies it is found that maternal childcare is another important determinant of child educational attainment the results are robust after controlling for endogeneity the iv estimates show that once childcare time is controlled for child health does not have an effect on school enrolment age this finding suggests that omitting the childcare time may have biased the estimated effect of child health on school enrolment in previous studies

optimal financial aid policies for a selective university our paper provides a model of optimal financial aid policies for a selective university the model implies that the financial aid package to be offered to each category of admitted applicants depends on the elasticity of the fraction who accept offers of admission with respect to the financial aid package offered them the propensity of the category to enroll the elasticity of the category s average quality with respect to the number admitted and the relative weight the university assigns them in the utility function while the latter must be determined subjectively the former parameters are subject to empirical estimation we conclude with a study of one institution s data and illustrate how they may be estimated these estimates are then applied to illustrate what the optimal financial aid policy would be for the university

individual attributes and self selection of higher education college attendance versus college completion abstract we have estimated a joint discrete continuous utility maximization model of college attendance and college completion special attention is given to the possibility that test scores and other individual attributes are poor predictors of who will succeed in college and thus may not promote optimal investment decisions and may indeed unjustly limit the educational opportunities of some youth we find that 1 college attendance decisions are strongly commensurate with college completion persons who are unlikely to attend college would be very likely to drop out of even their first choice colleges were they to attend college human capital investment decisions are strongly mirrored by the likelihood that they will pay off 2 contrary to much of the recent criticism of the predictive validity of test scores we find that their informational content is substantial after controlling for high school class rank for example the probability of dropping out of the first choice college varies greatly with sat scores 3 individual self selection related to both measured and unmeasured attributes is the dominant determinant of college attendance

the definition of part time employment a switching regression model with unknown sample selection rejecting the standard less than thirty five hours per week categorization of part time workers this paper offers an empirically justified definition of the part time employed the definition is based on the distinction through wage payments that employers make between a high hours full time and a low hours part time group of workers a switching regression model of wage equations with deterministic but unknown sample selection is estimated resulting in a significant split between high hours and low hours workers that is higher than the standard definition wage differentials are calculated and decomposed and estimates from the structural choice model are presented copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

does education raise productivity or just reflect it education has an important effect on wages but it not clear whether this is because education raises productivity or because education is simply a signal of ability we implement a number of existing tests for discriminating between these two explanations and find that they do not support the signalling hypothesis however we have severe reservations about these results and we propose an alternative test based on changes in education incentives caused by changes in the minimum school leaving age in the 1970s using this idea we find that uk data appear to strongly support the human capital explanation an important issue in the economics of education is that an individual s education has an effect on wages paid in the labour market for example blundell et al 2003 uses detailed education and subsequent earnings information for a cohort of male individuals born in 1958 to estimate that the returns to a uk degree typically of 3 year duration relative to graduating from high school at 18 with 2 a level qualifications a necessary but not sufficient condition for admission to university is a 24 wage premium human capital explanations pioneered by becker 1962 and schultz 1963 suggest that the correlation between education and wages is due to education enhancing productivity however earnings may rise in response to education not because of any effect on productivity but simply because education may act as a signal of productivity employers believing that education is correlated with productivity will screen workers for their education and pay higher wages to the more educated the employers beliefs will be confirmed by their experience if it is the case that high productivity individuals signal this by choosing high levels of education it will be optimal for individuals to behave in this way if the cost of acquiring education is less for high productivity individuals than it is for low productivity individuals thus under reasonable conditions the market will be characterised by a separating equilibrium where higher productivity individuals choose higher levels of education than lower productivity workers and earn correspondingly higher wages the theory is largely due to spence 1973 1979 and the subsequent empirical literature was reviewed by groot and oosterbeek 1994 riley 2001 provides an excellent modern survey chevalier harmon and walker are fellows of iza in bonn and are affiliated with the institute for the study of social change issc in dublin this paper is part of the issc policy evaluation programme chevalier and walker are also affiliated with the centre for the economics of education at the london school of economics lse the support of all of these bodies for facilitating our collaboration is acknowledged harmon is grateful to university college london for their hospitality during his nuffield foundation new career development fellowship in the social sciences comments from steve machin and three anonymous referees greatly improved the exposition of this paper we are also grateful to richard blundell and to seminar participants at the lse and the tinbergen institute in amsterdam for their comments and to vincent o sullivan for excellent research assistance the usual disclaimer applies

subsidies for higher education who should pay the resource costs of higher education this paper investigates a simple model of the general equilibrium of the labor market with three skill levels those in the population with the lower level of intelligence and or sophistication can only become low skilled workers but the brighter segment of the population can become either high or medium skilled workers given the tax structure the welfare of each group is maximized by a unique subsidy rate on the cost of training high skilled workers under several circumstances the lower iq group wants a higher subsidy rate than will the group that benefits directly from the training

chinese companies awareness and perceptions of the emissions trading scheme ets evidence from a national survey in china abstract china announced the launch of a national emissions trading scheme ets in 2017 however companies appear show little enthusiasm for participation in the ets in china this paper identifies the factors affecting companies awareness and perceptions of ets by conducting a national survey based on an online questionnaire from may to november 2015 in seven carbon trading pilots the results indicate that companies attitudes towards the ets are positively influenced by government regulations and policy public relations management and estimated economic benefit of these public relations management is the decisive factor and estimated economic benefit is confirmed to be a relatively weak predictor a company s environmental and energy strategy exerts insignificant effects on its preference for the ets although the sampled companies are very willing to save energy and reduce emissions there exists an inverted u shape relationship between a company s level of mitigation technologies and its attitudes towards the ets the carbon price fails to stimulate companies to upgrade mitigation technologies the majority of companies treat participation in the ets only as a means of improving ties with governments as well as of earning a good social reputation rather than as a cost effective mechanism to mitigate greenhouse gas emissions

admission tuition and financial aid policies in the market for higher education we present an equilibrium model of the market for higher education our model simultaneously predicts student selection into institutions of higher education financial aid educational expenditures and educational outcomes we show that the model gives rise to a strict hierarchy of colleges that differ by the educational quality provided to the students we also develop a new estimation procedure that exploits the observed variation in prices within colleges identification is based on variation in endowments and technology it does not rely on observed variation in potentially endogenous characteristics of colleges such as peer quality measures and expenditures we estimate the structural parameters using data collected by the national center for education statistics and aggregate data from peterson s and the national science foundation

is bigger still better the decline of the wage premium at large firms author affiliation william e even evenwe muohio edudavid a macpherson david macpherson trinity edu acknowledgment we thank daniel becker christopher bollinger and barry hirsch for helpful comments 1 introductionlarge firms pay higher wages than small firms this fact was first documented nearly 100 years ago and has been confirmed by myriad studies since then considerable effort has been directed toward testing different theoretical explanations for the size premium these include the fact that larger firms employ a more skilled work force and provide them with more and better capital pay efficiency wages to deal with greater monitoring costs pay compensating differences for less pleasant working conditions or greater risk that results from the type of human capital that is acquired or share rents with workers because of union threats or monopoly profits while there has been extensive research attempting to determine the importance of these different explanations of the size premium a recent trend has gone unnoticed namely the firm size premium has fallen substantially over the past 20 years for example we show that workers in firms with over 500 workers earned 55 more than workers in firms with fewer than 25 workers in the early 1990s our most recent data indicate that the size premium dropped by 15 percentage points over the past 20 years we also show that the size premium fell much more rapidly among less educated workers for example among workers with less than a high school degree the size premium fell by 30 percentage points this study documents the trends in the size premium and explores some possible explanations for the trends section 2 provides an overview of the theoretical explanations and empirical evidence on the size premium in section 3 we discuss our data and review the evidence on trends in the size premium empirical analysis of the trends is provided in section 4 our main conclusions are as follows first the size premium dropped over the past 20 years for two primary reasons i the type of worker employed by large and small firms has become more similar over time and ii large and small firms have become more similar in terms of the ways in which they reward workers holding observed characteristics constant in addition while the size premium has diminished over time it remains quantitatively significant particularly among highly educated workers 2 backgroundoi and idson 1999 provide a wide ranging summary of the extant research on the size premium their review points out that the size premium was first documented nearly 100 years ago among female workers at textile firms their summary of empirical studies shows that the largest firms e g firms with 500 or more employees pay wages that are 30 50 higher than those of the smallest firms e g firms with fewer than 25 employees numerous theories for the size premium have been proposed and no single theory is capable of providing an empirical explanation for the entire size premium the more prominent theories for the size premium are based upon size related differences in monitoring costs capital technology working conditions monopoly power or union effects the monitoring costs explanation for the size premium first proposed by oi 1983 argues that greater monitoring costs at large firms cause them to hire more able workers to conserve on monitoring costs because larger firms hire more able workers wages increase with firm size in addition because of greater monitoring costs large firms may be more likely to pay efficiency wages or deferred pay to reduce monitoring problems and utilize higher capital labor ratios to conserve on the number of workers empirical evidence indicates that the greater use of advanced technology by large firms explains part of the size premium dunne and schmitz 1995 reilly 1995 tan and batra 1997 troske 1999 yu et al

academic admissions standards implications for output distribution and mobility we examine the trade offs implicit in academic admissions standards when students are charged cost based tuition and offered loans that remove liquidity constraints lowering entry requirements while holding graduation requirements fixed increases aggregate output and promotes a more equal distribution of wages but reduces relative income mobility and diminishes the scope for affirmative action lowering admissions standards while raising graduation requirements so that the number of graduates remains constant has little direct effect on output distribution or mobility but again reduces the scope for affirmative action income based affirmative action offers a better trade off between output and relative mobility than income neutral admissions jel d31 h42 i23 i28 j24

exploring new ways of assessing the effect of regulation on environmental management abstract studies indicate that while a variety of factors positively influence voluntary environmental management regulatory pressures are among the most important however most research examines samples representing large manufacturers or single industries essentially assuming a level of regulatory constraint using a sample of heterogeneous facilities this study finds that facilities can be classified according to the level of regulatory constraint and that group membership impacts the choice of environmental management strategy when assessed within a utility maximization framework more extensively regulated facilities implement more individual environmental management practices but participate in fewer formal voluntary environmental programs veps compared to other facilities

school quality and black white relative earnings a direct assessment the wage differential between black and white men fell from 40 percent in 1960 to 25 percent in 1980 it has been argued that this convergence reflects improvements in the relative quality of black schools to test this hypothesis we assembled data on pupil teacher ratios annual teacher pay and term length for black and white schools in the eighteen segregated states from 1915 to 1966 these data are linked to estimated returns to education for southern born men from different cohorts and states in 1960 1970 and 1980 improvements in the relative quality of black schools explain 20 percent of the narrowing of the black white earnings gap between 1960 and 1980

cluster analysis for portfolio optimization we consider the problem of the statistical uncertainty of the correlation matrix in the optimization of a financial portfolio by assuming idealized conditions of perfect forecast ability for the future return and volatility of stocks and short selling we show that the use of clustering algorithms can improve the reliability of the portfolio in terms of the ratio between predicted and realized risk bootstrap analysis indicates that this improvement is obtained in a wide range of the parameters n number of assets and t investment horizon the predicted and realized risk level and the relative portfolio composition of the selected portfolio for a given value of the portfolio return are also investigated for each considered filtering method we also show that several of the results obtained by assuming idealized conditions are still observed under the more realistic assumptions of no short selling and mean return and volatility forecasting based on historical data

heterogeneous firms and the organization of production firms in the same industry exhibit systematic differences in the organization of production and the structure of employment entrepreneurial ability is the specific scarce input that limits the size of a firm this input must be allocated to two activities coordinating production and monitoring workers able entrepreneurs can convert calendar time into larger supplies of coordinating effort that enable them to assemble large firms greater ability implies a higher shadow price of time which increases the implicit costs of monitoring a dispersion of entrepreneurial abilities generates an equilibrium size distribution of firms differences in monitoring costs affect the choice of worker productivities the design of products and the organization of production the monitoring cost hypothesis advanced in this paper goes a long way in explaining the equilibrium of an industry containing heterogeneous firms that differ in size and behavior

does the birth order affect the cognitive development of a child this article investigates the link between position in the birth order and early scholastic ability using matched mother child data from the national longitudinal survey of youth 1979 cohort nlsy79 i find that being the first born is beneficial even after controlling for nonlinear effects of family size and child characteristics the verbal ability of first borns is about one tenth of a sd higher than for children in the middle of the birth order there is no evidence that last borns fare better than intermediate children the first born advantage is confirmed by estimates from within family variation models and i argue that the findings are consistent with the resource dilution hypothesis

growing apart the changing firm size wage premium and its inequality consequences wage inequality in the united states has risen dramatically over the past few decades prompting scholars to develop a number of theoretical accounts for the upward trend this study argues that large firms have been a prominent labor market institution that mitigates inequality by compensating their low and middle wage employees with a greater premium than their higher wage counterparts large u s firms reduced overall wage dispersion yet broader changes to employment relations associated with the demise of internal labor markets and the emergence of alternative employment arrangements have undermined large firms role as an equalizing institution using data from the current population survey and the survey of income and program participation we find that in 1989 although all private sector workers benefited from a firm size wage premium the premium was significantly higher for individuals at the lower end and middle of the wage distribution compared to those at the higher end between 1989 and

baseball specific human capital why good but not great players are more likely to coach in the major leagues the career choice of retiring athletes provides an interesting example of a midcareer transition conditioned on specific human capital previous research examines the determination of earnings in professional sports 3 5 14 but does not consider how skills developed during an athlete s playing years affect subsequent opportunities in this paper i test the hypothesis that skills specific to baseball increase the probability a player will choose to coach the empirical work confirms the importance of baseball specific human capital in the decision to coach and provides some of the first formal evidence that the opportunities of star players differ distinctly from players that are marginally less talented in the theoretical section i develop a random utility model in which a retiring player chooses between coaching and non coaching careers on the basis of potential earnings and a random taste component earnings in either career are determined by a vector of career attributes that embody the player s productivity in each if the random taste component is normally distributed the probability a player chooses a coaching career can be estimated using probit the empirical results support the predictions of the model that baseball specific human capital is positively correlated with the probability of a player coaching and that star players are unlikely to coach because their marginal skill advantage is not baseball specific in particular the findings imply that players with long but unexceptional careers are more likely to coach in the major leagues an extension of the empirical model is applied to the issue of discrimination the insignificance of a black dummy variable suggests that black players have the same probability of coaching as comparably skilled white players however a more complex interactive specification suggests that relatively poor opportunities for black stars outside the game leads to their crowding out those black players who if they were white would most likely coach

worker heterogeneity job screening and firm size a model of job screening is developed in which firms make wage offers to workers based on an imperfect evaluation of their abilities if large firms have higher costs of acquiring information about workers they screen workers with less accuracy and choose a wage compensation scheme different from the one small firms choose this generates the often observed positive correlation between firm size and wages the model also predicts that wage structure and perhaps wage dispersion will differ by firm size and that individuals who acquire more schooling will also choose to work in a larger firm these hypotheses are tested and supported using data from the national longitudinal survey

voluntary environmental agreements good or bad news for environmental protection abstract there has been growing interest in the use of voluntary agreements vas as an environmental policy tool this article uses a simple model to determine whether vas are likely to lead to efficient environmental protection we consider cases where polluters are induced to participate either by a background threat of mandatory controls the stick approach or by cost sharing subsidies the carrot approach the results suggest that the overall impact on environmental quality could be positive or negative depending on a number of factors including the allocation of bargaining power the magnitude of the background threat and the social cost of funds

non mandatory approaches to environmental protection the approach to environmental protection has been evolving from a regulation driven adversarial government push approach to a more proactive approach involving voluntary and often business led initiatives to self regulate their environmental performance this has been accompanied by increasing provision of environmental information about firms and products to enlist market forces and communities in creating a demand for corporate environmental self regulation by signaling their preferences for environmentally friendly firms this paper provides an overview of the non mandatory approaches being used for environmental protection and surveys the existing theoretical literature analyzing the economic efficiency of such approaches relative to mandatory approaches it also discusses empirical findings on the factors motivating self regulation by firms and its implications for their economic and environmental performance it examines the existing evidence on the extent to which information disclosure is effective in generating pressures from investors and communities on firms to improve their environmental performance
