effects of economic shocks on children s employment and schooling in brazil abstract this paper uses longitudinal employment survey data to analyze the impact of household economic shocks on the schooling and employment transitions of young people in metropolitan brazil the paper uses data on over 100 000 children ages 10 16 from brazil s monthly employment survey pme from 1982 to 1999 taking advantage of the rotating panels in the pme we compare households in which the male household head becomes unemployed during a four month period with households in which the head is continuously employed probit regressions indicate that an unemployment shock significantly increases the probability that a child enters the labor force drops out of school and fails to advance in school the effects can be large implying increases of as much as 50 in the probability of entering employment for 16 year old girls in contrast shocks occurring after the school year do not have significant effects suggesting that these results are not due to unobserved characteristics of households that experience unemployment shocks the results suggest that some households are not able to absorb short run economic shocks with negative consequences for children

overcoming selection bias in microcredit impact assessments a case study in peru abstract there are several potential sources of bias in microcredit impact assessments this paper uses a panel data set from a peruvian mfi to test for impact of credit on microenterprise profits while controlling for these biases we find that those who will eventually become borrowers have significantly higher incomes than those who will not become borrowers implying that selection into the lending programme is a substantial problem after controlling for this selection we find that an average microentrepreneur who borrows earns significantly higher enterprise profits than one who does not borrow and that naive models which do not control for selection overestimate this impact fixed effects estimates give roughly the same results as the quasi experimental cross section analysis

economic mobility and poverty dynamics in developing countries this study provides an introduction to this special issue of the journal of development studies on economic mobility and poverty dynamics in developing countries in addition to providing a conceptual framework it outlines how the contributions fit into the extant literature a series of regularities emerge across these studies the poor consist of those who are always poor poor at all dates and those who move in and out of poverty with the latter group tending to be strikingly large such movements in and out of poverty are apparent when looking at poverty in either absolute or relative terms changes in returns to endowments can be a potent source of increased incomes finally seemingly transitory shocks can have long term consequences the study concludes by drawing out the policy implications of these regularities

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

formal schooling and workforce participation in a rapidly developing economy evidence from compulsory junior high school in taiwan abstract using 18 consecutive household surveys this study explores the impact of taiwan s extension of tuition free education from 6 to 9 years upon schooling and labor market outcomes participation sector class of activity and work income i estimate upward shifts relative to preexisting trends of more than 0 4 years of education for males and 0 25 years for females in the first six cohorts affected by compulsory junior high schooling utilizing inter cohort variation within an instrumental variables iv strategy i find larger effects of schooling on females workforce participation and total earnings even controlling for selection

effects of family background on earnings and returns to schooling evidence from brazil we investigate whether omitted family background variables are responsible for high returns to schooling estimated in brazil returns to schooling fall by about one third when parental schooling is added to wage equations surprisingly the schooling of fathers in law has larger effects on wages than the schooling of fathers on the basis of a model of assortative mating we interpret this as evidence that parental characteristics represent unobservable worker attributes rather than nepotism in the labor market we conclude that the family background bias in returns to schooling is modest and need not imply returns to family connections

does marriage really make men more productive this paper presents new descriptive evidence regarding marital pay premiums earned by white males longitudinal data indicate that wages rise after marriage and that cross sectional marriage premiums appear to result from a steepening of the earnings profile data from a company personnelfile that includes information on job grades and supervisor performance ratings reveal large marital status pay differences within a narrow range of occupations managers and professionals and environments a single firm married workers tend to be located in higher paying job grades there are very small pay differentials within grades married men receive higher performance ratings than single men as a result they are much more likely to be promoted controlling for rated performance however eliminates the promotion differential sanders korenman is an assistant professor of economics and public affairs at princeton university and is a faculty associate of the office of population research at princeton university and a research affiliate of the national bureau of economic research nber david neumark is an assistant professor of economics at the university of pennsylvania and a research affiliate of the nber korenman wishes to acknowledge the hewlett foundation and the harvard university center for population studies for financial support the authors are grateful to james medofffor making available an extract from the company personnelfile questions regarding data availability should be directed to professor james

the quality of schooling comment a recent article in this review by jere behrman and nancy birdsall 1983 raises an important issue for makers of educational policy in developing countries behrmanbirdsall break ground both in specifying a model that treats schooling quantity and quality simultaneously and systematically and in developing practical methods for evaluating social rates of return to schooling quantity and quality in the absence of externalities their model is estimated using data from brazil a country with an impressive recent record in expanding primary schooling this comment has two objectives the first is to point out methodological errors made by behrman and birdsall in the derivation of the social rate of return to schooling quantity the second is to test the robustness of this corrected finding with a data set that differs from that used by behrman and birdsall the principal finding of the behrmanbirdsall analysis is that the estimated social rate of return to schooling quantity in brazil is much lower than that to schooling quality 6 8 vs 10 4 percent if this is generally the case in developing countries the possibility of a conflict between productivity and equity goals becomes an issue to be taken into account by educational policymakers for example with the conclusions reached by behrman birdsall if only one third of the students were to attend school and the resources saved by schooling only one third of the students could be used to increase both quality and quantity by 50 percent the estimates imply an overall income gain of 32 percent p 941 the analysis that follows demonstrates that correct procedure yields an estimated social rate of return to schooling quantity which is only slightly lower than that to schooling quality 9 8 vs 10 4 percent indicating no substantial inefficiency in the allocation of educational resources between schooling quantity and quality to test the robustness of this result a model of the behrmanbirdsall type is estimated using a 1979 set of micro data from one city in the brazilian northeast using theoretically and empirically preferred variable definitions very similar estimation results are obtained with respect to relative social rates of return to quantity and quality section i contains a correction of the errors made in deriving the social rate of return to schooling quantity section ii is empirical and contains a summary of potential sources of bias a description of the data set used to estimate a behrman birdsall type model and estimation results section iii contains a discussion of some remaining problems

the empirics of microfinance what do we know microfinance has received a lot of attention recently both from policy makers as well as in academic circles two of the main topics that have been hotly debated are explaining joint liability group lending and its implications for reducing information asymmetries and the trade off between the financial sustainability and outreach of microfinance programmes this feature contains three novel empirical contributions providing new insights with respect to why and how joint liability group lending works it also contains the first large scale systematic analysis of the trade off between financial performance and outreach of microfinance institutions

marriage markets labor markets and unobserved human capital an empirical exploration for south central india some aspects of the linkage between dimensions of unobserved human capital that are rewarded in the marriage market and in the wage market are explored it is postulated that in rural south central india the schooling age and dowry of a mans wife are determined by the mans observed characteristics schooling caste and those of his parents parental wealth parental occupation and dimensions of his unobserved by the researcher human capital the theoretical model consisted of two sets of equations the first describing the determination of the wifes characteristics through the marriage market and the second the determination of the mans wage and wage growth and his participation in the wage market the data were part of the village level studies vls conducted in rural semiarid south india a total of 120 households from 3 villages were surveyed continuously over the period 1975 76 to 1984 85 detailed information was obtained on farm management income consumption time allocation and asset ownership the mans schooling had a significant effect on his wifes schooling and on her age the characteristics of the mans parental household had a significant effect on each of the 3 observed characteristics of his wife the year of marriage significantly increased the wifes schooling by 0 08 year per year the net dowry 1 2 per year and the wifes age at marriage by 0 24 years per year schooling had a significant impact on a mans participation in the wage market and on wage growth a mans unobserved human capital generally had a significant and positive effect on his wage rate and wage growth though a negative effect on participation in the wage market some important dimensions of human capital beyond schooling had important effects in both marriage and labor markets potential brides and parents presumably value such characteristics because they increase the expected earning power of potential husbands

why do schooling returns differ screening private schools and labor markets in the philippines and thailand abstract this article examines returns to schooling in the philippines and thailand using recent employee surveys in manufacturing industries empirical results show that i schooling returns steadily increase as education attainment increases in thailand but the returns increase only at university level in the philippines and that ii private school premiums are higher in the philippines than thailand the latter finding is consistent with the dominance of private institutions in the philippine education system the premiums from private schooling investments in the philippines are however found to be spurious in the sense that private schools screen high ability students which augments wage therefore the productivity gain from private schooling is small

decomposing intergenerational income elasticity the gender differentiated contribution of capital transmission in rural philippines summary using longitudinal data from rural philippines we decompose intergenerational income elasticity ige into five distinct pathways intergenerational transmissions of health education land and spouse education capital plus residual correlation in productivity intergenerational human capital transmissions from mothers are stronger than those from fathers maternal education is the parental capital most strongly associated with ige while naive ige estimates are indistinguishable for sons and daughters the pathways that generate these results differ strikingly for sons ige is entirely explained by parent to child capital transmission by contrast strong income correlation exists between daughters and parents even after controlling for parent and child capital endowments

assessing the impact of microcredit a zambian case study expectations are high but evidence of the impact of microcredit remains in short supply this article estimates the impact of an urban credit programme in zambia on business performance and on a range of indicators of wellbeing borrowers who obtained a second loan experienced significantly higher average growth in business profits and household income inflexible group enforcement of loan obligations resulted in some borrowers especially amongst those who had taken only one loan being made worse off our methodological investigations suggest that the supply of rigorous impact studies can be increased by basing them on data collection that serves a wider range of purposes including market research

a shadow price frontier measurement of profit efficiency in chinese agriculture a shadow price profit frontier model is developed to examine production efficiency of chinese farm households the model incorporates price distortions but retains the advantages of stochastic frontier properties the shadow prices and shadow profit are derived through a behavioral profit function empirical results using household survey data show that the conventional assumption of profit maximization based on market prices is inappropriate farmers resource endowment and education influence their allocative efficiency family size per capita net income and family members operating as village leaders are positively related to households production efficiency reducing market distortions should increase farm households production efficiency

calibration of option based probability assessments in agricultural commodity markets a method for evaluating the reliability of option based price probability assessments is developed based on the calibration concept empirical tests using goodness of fit criteria are applied to four agricultural commodities results suggest that assessments in the corn and live cattle markets are reliable but such assessments overstate the volatility of soybean prices and understate the location of hog prices

impact of copula choice on the modeling of crop yield basis risk a number of problems in agricultural economics involve modeling joint distributions for which the assumption of multivariate normality may not be warranted yet very little work has been conducted evaluating competing methods for modeling joint dependence we develop a simulation framework to evaluate the bias and efficiency impacts of copula choice in the context of evaluating county to farm basis risk the results suggest significant differences in performance across various copulas and approaches the findings have important implications for risk analysis insurance and policy modeling problems in agriculture regarding the selection of method to model dependence among random variables

price changes supply elasticities industry organization and dairy output distribution long run price elasticities of milk supply are decomposed into price elasticities of yield herd size and farm population for northeastern u s dairy farms these elasticities are shown to vary with farm size because of size related differences in capital intensity specialization yield and herd size variability and rates of entry exit into dairy in the short run price responsiveness is shown to decrease with farm size in the long run large farms are shown to be most price responsive results suggest that lower milk prices could make revenue distribution less equal in both the short and long run by altering output and population distributions

education experience and allocative efficiency a dual approach a generalization of the dual non frontier profit function approach to evaluating allocative efficiency is developed that allows for training human capital variables to influence the efficiency level directly an application to pennsylvania dairy indicates that education and experience are substitutes and play a significant role in the level of efficiency while these operators are not allocating their variable inputs in an absolutely efficient manner relative efficiency can be achieved for four of six possible input combinations for prescribed levels of education and experience furthermore the estimates of the efficiency measures suggest that these operators are maximizing production rather than short run profits

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

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

copula based models of systemic risk in u s agriculture implications for crop insurance and reinsurance contracts the federal crop insurance program has been a major fixture of u s agricultural policy since the 1930s and continues to grow in size and importance indeed it now represents the most prominent farm policy instrument accounting for more government spending than any other farm commodity program the 2014 farm bill further expanded the crop insurance program and introduced a number of new county level revenue insurance plans in 2013 over 123 billion in crop value was insured under the program crop revenue insurance first introduced in the 1990s now accounts for nearly 70 of the total liability in the program the available plans cover losses that result from a revenue shortfall that can be triggered by multiple dependent sources of risk either low prices low yields or a combination of both the actuarial practices currently applied when rating these plans essentially involve the application of a gaussian copula model to the pricing of dependent risks we evaluate the suitability of this assumption by considering a number of alternative copula models in particular we use combinations of pair wise copulas of conditional distributions to model multiple sources of risk we find that this approach is generally preferred by model fitting criteria in the applications considered here we demonstrate that alternative approaches to modeling dependencies in a portfolio of risks may have significant implications for premium rates in crop insurance

risk wealth and sectoral choice in rural credit markets we model the role of the informal credit sector in developing countries the informational advantage of informal lenders is portrayed as the ability to monitor borrowers monitoring reduces the incentive problem and allows for contracts with lower collateral this enables informal lenders to serve both individuals who cannot post the collateral required by the formal sector and those who are able but do not want to post collateral the model is consistent with the conventional view of the informal sector as recipient of spillover demand from the formal sector it also shows that the informal sector may provide partial insurance as the lower collateral requirement implies greater consumption smoothing for borrowers

microenterprise credit programs deja vu abstract microenterprises in low income countries are the target of an increasing number of credit programs these efforts resemble earlier problematic attempts to assist operators of small farms with credit similarities discussed include target group definition assumptions policies and project justifications authors go on to list a dozen lessons from the experience with small farmer credit that might apply to microenterprise credit efforts authors then conclude that debt is not an effective tool for helping most poor people to enchance their economic conditions be they operators of small farms or microenterprises

an application of the dea double bootstrap to examine sources of efficiency in bangladesh rice farming in this article we examine sources of technical efficiency for rice farming in bangladesh the motivation for the analysis is the need to close the rice yield gap to enable food security we employ the dea double bootstrap of simar and wilson 2007 to estimate and explain technical efficiency this technique overcomes severe limitations inherent in using the two stage dea approach commonly employed in the efficiency literature from a policy perspective our results show that potential efficiency gains to reduce the yield gap are greater than previously found statistically positive influences on technical efficiency are education extension and credit with age being a negative influence

does having a cadre parent pay evidence from the first job offers of chinese college graduates abstract we estimate the wage premium associated with having a cadre parent in china using a recent survey of college graduates carried out by the authors the wage premium of having a cadre parent is 15 and this premium cannot be explained by other observables such as college entrance exam scores quality of colleges and majors a full set of college human capital attributes and job characteristics these results suggest that the remaining premium could be the true wage premium of having a cadre parent

economic interpretations of intergenerational correlations science itself for example see galton s 1869 study of the eminence of relatives or his 1889 analysis of the heights of parents and children but extensive use of economic theory to interpret these correlations is much more recent using basic economic concepts such as supply demand investment incentives missing markets and so on theorists hope to explain how and why status is correlated across generations economic theory might provide a unified treatment of a variety of socioeconomic indicators such as earnings income occupation or wealth or it might predict how taxes subsidies and economic regulation affect intergenerational mobility and the operation of markets however while the subject matter earnings consumption wealth occupa tion is clearly interesting to economists it could nonetheless be the case that beyond basic questions of measurement economic theory has not improved our understanding of intergenerational mobility goldberger 1989 is quite explicit in this contention by emphasizing the distinction between genes and environment and by using statistical theory as its main analytical tool the paper by samuel bowles and herbert gintis in this issue implicitly concurs with goldberger we take this challenge very seriously what characterizes an economic approach to mobility while biologists and bowles and gintis distinguish endowments and investments by their source genetic versus environmental factors one focus of economic theorists is motiva

outstanding female economists in the analysis and practice of development economics abstract this article examines the contributions of five eminent economists all women to the analysis and practice of development economics irma adelman frances stewart and nancy birdsall are leading advocates of alternative development strategies that focus on poverty alleviation and investment in human capital anne krueger and alice amsden stand at the forefront of two opposing camps in a lively and long lasting debate on the appropriate role of government in trade and industrialization we use the storied careers of these economists as a vehicle to convey the big picture of how development economics has evolved and which topics have proved durable

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

tails curtailed accounting for nonlinear dependence in pricing margin insurance for dairy farmers livestock gross margin insurance for dairy cattle lgm dairy is a risk management tool for protecting milk income over feed cost margins in this article we examine the assumptions underpinning the method used to determine lgm dairy premiums analysis of the milk feed dependence structure is conducted using copula methods a rich set of tools that allow modelers to capture nonlinearities in dependence among variables of interest we find a significant relationship between milk and feed prices that increases with time to maturity and severity of negative price shocks extremal or tail dependence is the propensity of dependence to concentrate in the tails of a distribution a common theme in financial and actuarial applications and in agricultural crop revenue insurance is that tail dependence increases the risk to the underwriter and results in higher insurance premiums we present to our knowledge the first case in which tail dependence may actually reduce actuarially fair premiums for an agricultural risk insurance product we examine hedging effectiveness with lgm dairy and show that even in the absence of basis or production risk hedging horizon plays an important role in the ability of this tool to smooth farm income over feed cost margins over time rating methodology that accounts for tail dependence between milk and feed prices extends the optimal hedging horizon and increases hedging effectiveness of the lgm dairy program

causal pitfalls in the decomposition of wage gaps the decomposition of gender or ethnic wage gaps into explained and unexplained components often with the aim to assess labor market discrimination has been a major research agenda in empirical labor economics this article demonstrates that conventional decompositions no matter whether linear or nonparametric are equivalent to assuming a probably too simple model of mediation aimed at assessing causal mechanisms and may therefore lack causal interpretability the reason is that decompositions typically control for post birth variables that lie on the causal pathway from gender ethnicity which are determined at or even before birth to wage but neglect potential endogeneity that may arise from this approach based on the newer literature on mediation analysis we therefore provide more attractive identifying assumptions and discuss nonparametric identification based on reweighting

financial performance and outreach a global analysis of leading microbanks microfinance contracts have proven able to secure high rates of loan repayment in the face of limited liability and information asymmetries but high repayment rates have not translated easily into profits for most microbanks profitability though is at the heart of the promise that microfinance can deliver poverty reduction while not relying on ongoing subsidy the authors examine why this promise remains unmet for most institutions using a data set with unusually high quality financial information on 124 institutions in 49 countries they explore the patterns of profitability loan repayment and cost reduction the authors find that institutional design and orientation matter substantially lenders that do not use group based methods to overcome incentive problems experience weaker portfolio quality and lower profit rates when interest rates are raised substantially for these individual based lenders one key to achieving profitability is investing more heavily in staff costs a finding consistent with the economics of information but contrary to the conventional wisdom that profitability is largely a function of minimizing cost

tracing the evolution of the aggregate u s milk supply elasticity using a herd dynamics model the u s dairy sector is characterized by increasing volatility of milk prices and consolidation in production as evidenced by declining number of dairy farms with an increasingly larger share of milk supplied from a small number of very large farms using aggregate national data we build a mixed frequency herd dynamics econometric model of the u s milk supply that updates and substantially amends the model first proposed by chavas and klemme we implement a dynamic residual based bootstrap technique that can be used in testing for changes in nonmarginal simulated long run supply responsiveness and trace the evolution of long run milk supply elasticity from 1975 through 2010 several papers in the past have suggested that long run supply elasticity increases with dairy farm size which implies that increased importance of large farms would increase aggregate long run supply responsiveness contrary to this conclusion we find a declining trend in long run supply elasticity from 1975 through 2005 persistence of such a decline would be a major cause for worry as ever larger price swings would be needed to equilibrate the market in face of demand shocks however we find that milk supply is becoming more responsive since 2005 both to milk and feed price changes increasing responsiveness to feed prices further justifies focusing the next generation of the dairy policy instruments on managing dairy profit margins rather than just revenue streams

price distortions and resource use efficiency in indian agriculture a restricted profit function approach this paper develops a generalized profit function that incorporates price distortions resulting from imperfect market conditions sociopolitical and institutional constraints as well as technical and allocative inefficiency the model is applied to test 1 the appropriateness of the neoclassical profit function and 2 the effect of education and farm size on allocative performance using farm level data from indian agriculture empirical results reject the neoclassical profit maximization hypothesis based on market prices in favor of the general model with price distortions and therefore help to improve allocation of inputs and output farm size is found to reduce price distortions only for small farmers copyright 1992 by mit press

the informational content of surnames the evolution of intergenerational mobility and assortative mating we propose a new methodology for measuring intergenerational mobility in economic well being our method is based on the joint distribution of surnames and economic outcomes it circumvents the need for intergenerational panel data a long standing stumbling block for understanding mobility it does so by using cross sectional data alongside a calibrated structural model to recover the traditional intergenerational elasticity measures our main idea is simple if inheritance is important for economic outcomes then rare surnames should predict economic outcomes in the cross section this is because rare surnames are indicative of familial linkages if the number of rare surnames is small this approach will not work however rare surnames are abundant in the highly skewed nature of surname distributions from most western societies we develop a model that articulates this idea and shows that the more important is inheritance the more informative will be surnames this result is robust to a variety of different assumptions about fertility and mating we apply our method using the 2001 census from catalonia a large region of spain we use educational attainment as a proxy for overall economic well being a calibration exercise results in an estimate of the intergenerational correlation of educational attainment of 0 60 we also find evidence suggesting that mobility has decreased among the different generations of the 20th century a complementary analysis based on sibling correlations confirms our results and provides a robustness check on our method our model and our data allow us to examine one possible explanation for the observed decrease in mobility we find that the degree of assortative mating has increased over time overall we argue that our method has promise because it can tap the vast mines of census data that are available in a heretofore unexploited manner

rates of return on physical and human capital in africa s manufacturing sector in this paper two sets of issues are addressed using panel data from the manufacturing sector of five african countries first how high are the returns to human relative to physical capital second what is the relative importance of technology and endowments of human and physical capital in determining differences in earnings and productivity across the countries evidence from earnings functions shows that the private returns to both experience and education rise with the level of education private returns rise from 3 per cent at the primary level to 10 per cent at the secondary level and 35 per cent for tertiary evidence from the production function gives lower returns on education than from the earnings function rates of return on physical capital exceed 20 per cent and greatly exceed the average return on human capital data is available on the stocks of human and physical capital across the countries productivity and earnings differentials are shown to be large between cameroon and ghana these differences are due almost entirely to differences in physical not human capital endowments this abstract was borrowed from another version of this item

attracting talent location choices of foreign born phds in the united states we analyze location choices of foreign born science and engineering students receiving phds from us universities foreign students who stay in the united states are positively selected on observables they tend to stay in the united states during periods of strong us economic growth and during periods of weak home country economic growth foreign students from higher income countries and from recently democratized countries tend not to remain in the united states education and innovation may therefore be part of a virtuous cycle by which education enhances a country s prospects for innovation and innovation makes the country more attractive for scientists and engineers

some recent developments in futures hedging the use of futures contracts as a hedging instrument has been the focus of much research at the theoretical level an optimal hedge strategy is traditionally based on the expected utility maximization paradigm a simplification of this paradigm leads to the minimum variance criterion although this paradigm is quite well accepted alternative approaches have been sought at the empirical level research on futures hedging has benefited from the recent developments in the econometrics literature much research has been done on improving the estimation of the optimal hedge ratio as more is known about the statistical properties of financial time series more sophisticated estimation methods are proposed in this survey we review some recent developments in futures hedging we delineate the theoretical underpinning of various methods and discuss the econometric implementation of the methods

a socio economic study of the borrowing process the case of microentrepreneurs in jordan this paper investigates the socio economic determinants of four stages of borrowing process of the jordanian microfinance market the equations and functions corresponding to the stages of the borrowing process are estimated using a sample of 474 microentrepreneurs the main results are as follow variables that reflect the repayment ability are the main determinants of credit rationing in the microfinance market religious beliefs social responsibilities availability of local microfinance provides application costs level of knowledge about microfinance providers significantly affect the borrowing process of microentrepreneurs credit rationing is found to be a problem for some applicants but not for the majority

the relationship between credit and productivity in chinese agriculture a microeconomic model of disequilibrium credit is an important element in agricultural production systems it allows producers to satisfy the cash needs induced by the production cycle which characterizes agriculture preparation planting cultivation and harvesting of the crops are typically done over a period of several months in which very little cash revenue is earned while expenditures on materials purchased inputs and consumption must be made in cash cash income is received a short time after the harvest in the absence of credit markets farmers would have to maintain cash reserves so as to facilitate production and consumption in the next cycle the availability of credit allows both greater consumption and greater purchased input use and thus increases welfare of the farmers

who marries whom in a surging housing market abstract this paper investigates the impact of a surging housing market on marital sorting our empirical analysis shows that there is increasing assortativeness on original family background in response to housing price appreciation that is for husbands when the down payment doubles one more year of paternal schooling predicts a marriage in which the father in law s schooling is 0 057 year greater than in a scenario in which the down payment does not increase the rising assortativeness could exacerbate the already expanding inequality caused by the booming housing market in addition to the benchmark analysis we find that a divorce reform which awards assets proportionate to the shares the spouses paid for the initial down payment rather than awarding equal shares upon divorce alleviates assortativeness the evidence suggests that joint investment in housing is likely to be a significant consideration in marital sorting

why governments should invest more to educate girls abstract women and men often receive the same percentage increase in their wage rates with advances in schooling because these returns decline with more schooling the marginal returns for women will tend to exceed those for men especially in countries where women are much less educated the health and schooling of children are more closely related to their mother s education than father s more educated women work more hours in the market labor force broadening the tax base and thereby potentially reducing tax distortions these three conditions it is argued justify the disproportionate allocation of public expenditures toward women s education

declining inequality in schooling in brazil and its effects on inequality in earnings abstract household survey data demonstrate that brazilian males born between 1925 and 1963 experienced steady increases in mean schooling and significant declines in schooling inequality the variance in years of schooling increased for cohorts born up until 1950 with steady declines for more recent cohorts decomposition of a standard human capital earnings equation indicates that trends in schooling tended to reduce earnings inequality from 1976 to 1985 due to reductions in both the variance of schooling and in returns to schooling these improvements were more than offset however by increases in other sources of inequality although the net increase in earnings inequality from 1976 to 1985 is disturbing the reduction in schooling inequality represents a fundamental improvement in the determinants of earnings inequality in brazil that will have beneficial effects for decades

marriage markets and assortative mating with household public goods theoretical results and empirical implications this paper analyzes marriage market equilibria when the gains from marriage result from joint consumption of household public goods assuming transferable utility within marriage the paper proves that marriage markets will be characterized by positive assortative mating on wealth when spouses differ only in endowments and the gains to marriage result only from public goods when spouses differ in wages and household public goods are produced at home the results imply offsetting effects with public good economies creating an incentive for positive assortative mating on wages and gains from specialization creating an incentive for negative assortative mating on wages the results help explain the persistent lack of empirical support for becker s prediction of negative assortative mating on wages and have implications for empirical analysis of all joint living arrangement decisions

profit margin hedging some extension economists and others recommend profit margin hedging as a way to choose the timing of crop sales however the theory behind this strategy recommendation is not well developed this article determines the producer s utility function and price processes where profit margin hedging is optimal profit margin hedging is shown to be an optimal strategy under a highly restricted target utility function even in an efficient market profit margin hedging is profitable if prices are mean reverting copyright 2010 oxford university press

an investigation of the labor market earnings of panamanian males evaluating sources of inequality this paper presents empirical evidence on the determinants of labor market earnings and inequality for males in panama using newly available microdata we estimate earnings equations based on the measurement framework of mincer 1974 and compare them with those for other countries at various stages of economic development we present evidence on two aspects of inequality in less developed economies labor market segmentation and social stratification we present tests of the segmentation hypothesis including several of the dual labor market hypotheses and discuss their inherent ambiguity we also present evidence on the importance of family background for earnings determination and educational attainment

marital matching and earnings evidence from the unmarried population in sweden social scientists have devoted substantial research to economic basis for matching of men and women in marriage a common feature of existing studies is their reliance on samples of married couples the principal shortcoming of spouse data is that spouses earnings correlations are contaminated by the partners behaviors and other events that occur after marriage and affect their earnings this study addresses that problem by exploiting a longitudinal data file from the swedish population by selecting a sample of married couples in a given year we retreat through the file to years before the marriage using data from the spouses single years we apply the correlation methodology to their earnings evidence from the model supports positive assortative mating

an examination of the effect of ownership on the relative efficiency of public and private water utilities the behavior of privately and publicly owned water utilities is examined by estimating a generalized variable cost function containing the regular characteristics of the neoclassical cost function without requiring that cost minimization subject to market prices be imposed as a maintained hypothesis assuming that unobserved shadow prices reflect the regulatory environment of the water industry tests for cost minimization are obtained by deriving shadow prices as functions of market prices the empirical results provide evidence that public water utilities are more efficient than private utilities on average but are more widely dispersed between best and worst practice

the quality of schooling quantity alone is misleading although much research discusses the quantity of schooling as an effective impact on productivity and earnings most such research leaves out the idea of the quality of schooling which may cause biases in the estimated returns to schooling this paper consequently attempts to extend the standard mincerian approach to incorporate school quality as well as quantity it demonstrates how exclusion of quality in the standard procedure may cause biases in the estimated returns to years of schooling probably in the upward direction the paper explores the implications of this extension of the standard model for the case of young brazilian males it shows that the estimate of the private return to years of schooling using the preferred quality inclusive specification is only one half the estimate using the standard procedure indicating substantial upward bias in the standard estimates it further outlines a method for estimating a social return to quality and finds that it exceeds substantially the social return to quantity the paper then shows why this in turn suggests there may be an equity productivity trade off in schooling investments

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

effects of family and community background on economic status policy oriented discussions of poverty in the united states repeatedly have stressed the large influence of family and community background on income status in this paper we use a simple statistical model to explain how problems of measurement error and unrepresentative samples have caused previous statistical studies to underestimate the magnitude of background effects we then summarize a series of our own studies in which we have corrected for the biases in earlier studies and estimated substantially larger background effects the empirical analysis is based on data from the panel study of income dynamics excerpt

formal and informal rural credit in four provinces of vietnam abstract this paper uses a survey of 932 rural households to uncover how the rural credit market operates in vietnam households obtain credit through formal and informal lenders formal loans are almost entirely for production and asset accumulation while informal loans are used for consumption smoothening the determinants of formal and informal credit demand are distinct while credit rationing depends on education and credit history in particular regional differences in the demand for credit are striking a one size fits all approach to credit policy in vietnam would be inappropriate
