rates of return to human capital a test using el salvador data most of the empirical work on human capital has been confined to conditions in developed countries this is probably due to difficulties in obtaining data for other countries it would be interesting to see how robust the theory and its associated models are in conditions regarded as typical for developing countries this will be considered here using a large data set describing the el salvador labor market two questions will be examined namely a how well does the earnings function of the human capital theory explain earnings distribution in el salvador and b does the return to training called experience here approximate the return to school as is often assumed in human capital research the latter issue is of course related to the notion of overtaking the point in the experience profile when the flat earnings stream is intersected from below by the earnings stream affected by postschool investments

information school choice and academic achievement evidence from two experiments we examine a natural experiment and a field experiment that provided direct information on school test scores to lower income families in a public school choice plan receiving information significantly increases the fraction of parents choosing higher performing schools parents with high scoring alternatives nearby were more likely to choose nonguaranteed schools with higher test scores using random variation from each experiment we find that attending a higher scoring school increases student test scores the results imply that school choice will most effectively increase academic achievement for disadvantaged students when parents have easy access to test score information and good options from which to choose

the role of application assistance and information in college decisions results from the h r block fafsa experiment growing concerns about low awareness and take up rates for government support programs like college financial aid have spurred calls to simplify the application process and enhance visibility we present results from a randomized field experiment in which low income individuals receiving tax preparation help were also offered immediate assistance and a streamlined process to complete the free application for federal student aid fafsa for themselves or their children treated participants were also provided with aid estimates that were compared against tuition cost amounts for nearby colleges the combined assistance and information treatment substantially increased fafsa submissions and ultimately the likelihood of college attendance persistence and aid receipt in particular high school seniors whose parents received the treatment were 8 percentage points more likely to have completed two years of college going from 28 to 36 during the first three years following the experiment families who received aid information but no assistance with the fafsa did not experience improved outcomes the findings suggest many other opportunities for using personal assistance to increase participation in programs that require filling out forms to become eligible jel codes i2 h4 j24 copyright 2012 oxford university press

entrepreneurial human capital and the long run survival of firms in india abstract this paper analyses the characteristics of entrepreneurs that contribute to firms survival in less developed countries ldcs the study which relies on data collected in a 1971 survey of entrepreneurs in south india and a follow up survey of surviving firms in 1993 finds that entrepreneurial human capital greatly influences firm survival the results indicate that firms founded by older entrepreneurs in higher castes are most likely to survive but that increased education of the founding entrepreneur reduces survival these results provide evidence that opportunities of entrepreneurs outside the firm ignored in most theories are important in firm survival

the perceived returns to education and the demand for schooling economists emphasize the link between market returns to education and investments in schooling though many studies estimate these returns with earnings data it is the perceived returns that affect schooling decisions and these perceptions may be inaccurate using survey data for eighth grade boys in the dominican republic we find that the perceived returns to secondary school are extremely low despite high measured returns students at randomly selected schools given information on the higher measured returns completed on average 0 20 0 35 more years of school over the next four years than those who were not

if we knew ability how would we tax individuals abstract the suggestion to tax people on earnings capacity instead of earnings has been around for a long time and is attractive in terms of economic efficiency in this paper we reflect on the feasibility of such a system and give an exploratory empirical implementation we apply the leyden welfare function of income a survey based measure of an individual s welfare associated with income to derive implications for ability taxation under the assumption that iq and schooling reflect earnings capacity we derive the tax functions using different criteria to distribute the utility loss due to taxation

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

a critical evaluation of rate of return analysis since the development of the concept of human capital schultz i 96 i becker i964 analysis of rates of return has been a standard means of assessing education the conventional way of measuring the return to education is to take a snap shot view of the earnings of people with differing educational experiences it is then possible to calculate the average income earned at different stages of a working life the rate of return to education can then be calculated as the internal discount rate which equates the discounted increment to average earnings to the costs involved in obtaining education both private and social rates of return can be calculated provision of education is often subsidised so that the private cost is lower than the social cost and this will tend to raise the private return above the social return taxation of the private benefit of education offsets this at least partly however ziderman i 973 records that in developed countries private returns normally exceed social returns this pattern is confirmed by psacharopoulos i985 in many cases it is not possible to calculate a full rate of return but one can look at the incremental effect of schooling on earning power thus denison i 967 suggests that in the united states each year of education raises earning power by an average of around 5 6 with the effect tending to rise with the duration of education card and kruger i992 identify effects of similar magnitude it need not be the case that education goes on raising earning power overeducation is clearly possible rudd i990 suggests that in the social sciences education beyond degree level is very damaging to earnings prospects tarsh i992 questions aspects of rudd s study but agrees that higher education graduates do suffer some pay disadvantage rate of return calculations can form the basis for policy decisions in principle social returns to investment in human capital could be compared with those on physical capital so as to give a basis for the allocation of resources between the two types of investment estimates of social rates of return to different types of education could also be used to guide expenditure decisions between these different types however there are many possibly offsetting biases entering into the calculations of rates of return and it is perhaps concern with these that has

the long term patterns of regional income inequality in spain 1860 2000 martinez galarraga j roses j r and tirado d a the long term patterns of regional income inequality in spain 1860 2000 regional studies building on a new estimation of regional gross domestic product gdp from 1860 to 2000 this paper evaluates the long run evolution of regional income inequality in spain it is found that sustained economic growth and the progressive integration of national markets have been accompanied by an inverted u shaped evolution of regional income inequality regional inequality in income per worker rose during the second half of the nineteenth century peaked in the year 1900 and decreased over the following ninety years since 1990 together with the exhaustion of the convergence in regional productive structures spain s membership in the european union generated a new upsurge of differences in labour productivity across the country that could be the basis for a new phase of regional income divergence

education choices and returns to schooling mothers and youths subjective expectations and their role by gender abstract in this paper we investigate the role of expected returns to schooling and of perceived risks of unemployment and earnings as determinants of schooling decisions moreover our data also allow us to analyze whether youths and or mothers expectations predict schooling decisions and whether this depends on the age and gender of the youth in particular we use mexican data that contain labor market expectations of mothers and youths we find that expected returns and risk perceptions are important determinants of schooling decisions the latter in particular from the perspective of the mother boys expectations predict the decision to enter college but not to enter high school while girls own expectations do not predict either of the two educational decisions mothers expectations are particularly strong predictors of their daughters decisions

school supply constraints and children s educational outcomes in rural ghana abstract studies of school attainment often fail to acknowledge the possibility that prices for all schooling levels affect the decision to attend any one schooling level in developing countries the assumption that schooling costs are constant throughout the education cycle is manifestly untrue this paper concentrates on the empirical implications of introducing schooling costs that increase with schooling level the results suggest that the cost of advanced levels of education influences decisions at the primary school level the relative magnitude of the cross price elasticities suggests that cross price effects should not be ignored when designing educational user fees

education choices and returns on the labor and marriage markets evidence from data on subjective expectations in this paper we analyze the role of expected labor and marriage market returns as determinants of the college enrollment decisions of mexican high school graduates moreover we investigate whether the relative weights of these factors differ by gender we use data on individuals expectations regarding future labor market outcomes which we directly elicited from the youths and two different measures of marriage market returns first marriage market returns are proxied by the net supply of potential partners in the youths local marriage markets second we use data which elicits youths beliefs about their future spouse s earnings conditional on their own education level we find that labor market as well as marriage market returns are important determinants of the college enrollment decision however boys and girls preferences differ in terms of the relative role of the two determinants in that the relative weight of labor market versus marriage market returns is larger for boys than for girls

intended college attendance evidence from an experiment on college returns and costs abstract we conduct an information experiment about college returns and costs embedded within a representative survey of us household heads baseline perceptions of college costs and benefits are substantially biased with larger biases among lower income and non college households respondents are randomly exposed to objective information about average college returns or costs we find a significant impact of the returns experiment persisting in a follow up survey two months later intended college attendance expectations increase by about 0 2 of the standard deviation in the baseline likelihood and gaps by household income or parents education decline by 20 30 we find no impact of the cost information treatment further analysis supports the information s salience as opposed to information based updating as the main channel through which the returns intervention impacts intentions

a club convergence analysis of per capita energy consumption across australian regions and sectors we examine convergence in per capita energy consumption across nine sectors and seven states and territories in australia over the period 19902016 using the phillips sul club convergence approach we find evidence of multiple convergence clubs for aggregate energy consumption per capita and for energy consumption per capita in eight of the nine sectors with full club convergence in the case of electricity the presence of multiple equilibria for most sectors reflect that states with similar features in terms of climate economic activities and population size among others tend to exhibit similar energy consumption patterns our results highlight the need to tailor policies designed to reduce energy consumption in specific sectors to the consumption convergence paths unique to particular clusters of states

earnings functions for the self employed comment abstract the standard human capital earnings model is applied to data from a 1975 socioeconomic survey conducted in tehran iran results show that the returns to schooling for the self employed not including street vendors canvassers and newsvendors are statistically equivalent to those of wage and salary workers thus in contradiction to conclusions drawn from a study by chiswick 1976 the high rates of return to schooling found in many studies of less developed countries do not appear to be the result of the systematic exclusion of the self employed from the estimating samples in other words when wage and salary workers are compared with the self employed in similar occupations their earnings profiles are similar

the importance of information targeting for school choice although school choice programs are common we know little about the underlying decision making processes in this study we randomly assigned 900 junior high schools in ghana a country with universal secondary school choice to 1 of 3 treatment arms 1 information to students 2 information to students and guardians and 3 control group we observe changes in beliefs behaviors and the decision maker s identity through a survey of guardians our intervention increased the likelihood that guardians were involved with and informed about the school selection process moreover specifically targeting guardians led to significantly larger changes for most outcomes

training wages and sample selection estimating sharp bounds on treatment effects this paper empirically assesses the wage effects of the job corps program one of the largest federally funded job training programs in the u s even with the aid of a randomized experiment the impact of a training program on wages is difficult to study because of sample selection a pervasive problem in applied microeconometric research wage rates are only observed for those who are employed and employment status itself may be affected by the training program this paper develops an intuitive trimming procedure for bounding average treatment effects in the presence of sample selection in contrast to existing methods the procedure requires neither exclusion restrictions nor a bounded support for the outcome of interest identification results estimators and their asymptotic distribution are presented the bounds suggest that the program raised wages consistent with the notion that the job corps raises earnings by increasing human capital rather than solely through encouraging work the estimator is generally applicable to typical treatment evaluation problems in which there is nonrandom sample selection attrition copyright wiley blackwell

does aid matter measuring the effect of student aid on college attendance and completion does student aid increase college attendance or simply subsidize costs for infra marginal students settling the question empirically is a challenge because aid is correlated with many characteristics that influence educational investment decisions a shift in financial aid policy that affects some youth but not others can provide an identifying source of variation in aid in 1982 congress eliminated the social security student benefit program which at its peak provided grants totaling 3 7 billion a year to one out of ten college students using the death of a parent as a proxy for social security beneficiary status i find that offering 1 000 1998 of grant aid increases educational attainment by about 0 16 years and the probability of attending college by four percentage points the elasticities of attendance and completed years of college with respect to schooling costs are 0 7 to 0 8 the evidence suggests that aid has a threshold effect a student who has crossed the hurdle of college entry with the assistance of aid is more likely to continue schooling later in life than one who has never attempted college this is consistent with a model in which there are fixed costs of college entry finally a cost benefit analysis indicates that the aid program examined by this paper was a cost effective use of government resources this abstract was borrowed from another version of this item

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

investing in schooling in chile the role of information about financial aid for higher education we investigate the impacts of providing low income chilean adolescents with information about how to finance higher education and ask whether providing parents with the same information magnifies the effects on schooling outcomes we randomly assigned eighth graders and some parents to receive information about aid for higher education exposure to information raised college preparatory high school enrollment primary school attendance and financial aid knowledge with gains concentrated among medium and high grade students parental exposure to information did not significantly magnify these effects our results demonstrate that access to relevant information about financial aid affects important schooling choices long before tertiary education begins

do favorable land price policy affect renewable energy industry evidence from photovoltaics abstract renewable energy is necessary for sustainable social and economic development this is particularly so with global energy shortages the continuous deterioration of ecosystems and the environment as well as the world population explosion this article qualitatively and quantitatively analyzes the effects and problems of chinese favorable land price policy on photovoltaics in examining the favorable land price policy in china this study develops a multiple linear regression model to study the effects of favorable land price policy on photovoltaic power and photovoltaic industry data used in this research was mainly collected from 20 provinces in china it is found that the development of pv in china has been greatly affected by the favorable land price policy in the end it is highly recommended that favorable land price policy should be continued for renewable energy systemic deficiencies can be overcome through continual reform and innovation of mechanisms

intergenerational earnings mobility inequality and growth abstract we examine a model in which per capita income inequality intergenerational mobility and returns to education are all determined endogenously individuals earn wages depending on their ability which is a random variable they purchase an education with transfers received from their parents and are subject to liquidity constraints in the model multiple steady state equilibria are possible countries with identical tastes and technologies can reach differing rates of mobility inequality and per capita income equilibria with higher levels of output also have lower inequality higher mobility and more efficient distribution of education

wage functions and occupational selection in a rural less developed country setting economists are just beginning to develop empirical knowledge about the basic relationships that determine the distribution of incomes and allocation of resources in the poor rural regions of the world understanding interactions between agriculture and the rest of the economy is particularly important in this context this paper empirically investigates the allocation of human resources between farm work and other jobs and the compensation received by individuals for their work in agriculture and elsewhere specifically two related tasks are undertaken in this paper 1 the estimation of wage functions and 2 the estimation of functions determining the allocation of time among occupations there have been a series of papers which estimate the earnings function using data from poor countries for examples see blaug 1974 chiswick 1977 and valdes 1971 however this study focuses not on total earnings but on the wage rates a person may earn in labor market work because the wage rate is the relevant price of time for many allocative decisions for example in dividing the work year between self employed farming and work as an employee off the farm a key price is the potential wage rate the person can earn in the labor market for discussion and evidence on this issue see sumner 1978 recently a few studies have appeared which illustrate the importance of understanding potential wage variations across individuals in less developed countries rosenzweig 1978 uses wage estimates from aggregate indian data in a model determining the impact of land reform bardhan 1979 develops wage functions from a sample survey in rural india as a step in estimating labor supply for rural households kusnic and davanzo 1980 use wage functions to impute potential incomes and to measure the full income distribution these previous studies illustrate the importance of understanding the determinants of market wages the present paper develops wage functions in more detail focusing especially on industrial differentials in many rural areas employment opportunities may be usefully categorized into 1 self employment mainly on small farms 2 work for wages on large farms and 3 work for wages in non farm industries the combination of selfemployment and work as an employee is also important in many rural areas in both rich and poor countries this paper examines the impact of personal characteristics on the choice to participate in work for wages and on the choice of industry these estimates also form a basis for studying industrial wage differentials tentative estimates of the dependence of participation on expected wages are also presented below the empirical analysis in this paper is based on a 1974 sample of five villages in central guatemala see corona 1978 and stein 1978 one village petapa is larger richer and more urban than the others it lies south of guatemala city within commuting distance of the capital the other villages are outside the capital city region the population sampled is almost exclusively ladino spanish culture as opposed to indian data are available on the earnings hours of work industry age schooling literacy and village of 1 005 male heads of households approximately one third of the sample work as both self employed farmers and hired workers and most of these men work on fincas large plantations another quarter of the sample work as self employed farmers and do no work for wages the suburban village has mostly nonagricultural workers whereas the four other villages have predominantly farmers and farm employees in received for publication june 21 1979 revision accepted for publication december 31 1980 north carolina state university research on this paper began while i was a rockefeller foundation supported post doctoral fellow in the labor and population group of the economics department of the rand corporation and continued at north carolina state university supported by the agricultural research service at rand robert newman served as my research assistant and at n c state james cochell provided able assistance i have benefited from the comments of colleagues at both institutions and from members of the labor economics workshop at the university of north carolina at chapel hill i also thank two anonymous referees for useful suggestions this is paper number 6558 of the journal series of the north carolina agricultural research service raleigh n c

the behavioral and distributional implications of aid for college subsidizing the cost of education is one of the most common and expensive activities of governments while primary and secondary schooling is available tuition free in the united states among post secondary students the direct cost of schooling is quite heterogeneous first tuition prices vary widely across schools during the 2000 2001 academic year college tuitions varied from zero at some community colleges to over 27 000 at ivy league institutions second institutions heavily discount these sticker prices for many students using detailed information on family finances and academic merit to engage in finely tuned price discrimination third the federal and state governments provide individual subsidies such as the pell grant and low interest stafford loan that are portable across institutions the standard model of human capital clearly predicts that such cost subsidies will raise the optimal level of schooling while the theoretical predictions are clear it is an empirical question how much a given dollar of subsidy affects behavior answering this empirical question is a challenge since eligibility for subsidies is certainly not random and in fact is likely to be correlated with many other determinants of schooling as a result estimates based on the cross sectional correlation of aid eligibility with schooling are subject to multiple sources of bias this paper examines work that has used quasi experimental methodology to isolate exogenous sources of variation in schooling costs in order to determine their effect on schooling decisions

winners and losers from regional integration agreements how are the benefits and costs of a customs union divided between member countries outcomes depend on the comparative advantage of members relative to each other and relative to the rest of the world countries with a comparative advantage between that of their partners and the rest of the world do better than countries with an extreme comparative advantage consequently integration between low income countries tends to lead to divergence of member country incomes while agreements between high income countries cause convergence results suggest that developing countries are likely to be better served by north south than by south south agreements

gary becker s contributions to economics from his first published work gary becker has consistently strived to extend the domain of economic analysis his interest is in social science broadly defined and he is convinced that economic theory in its established neoclassical form provides the best set of tools for analysing social science questions when he finds an interesting problem on the borderland of what is conventionally thought of as economics and that is where he is looking for his problems he is not worried that he is trespassing on the traditional grounds of sociologists political scientists lawyers anthropologists or biologists on the contrary he clearly delights in showing how economic theory can be brought to bear on such problems he is of course not alone in trying to extend the borders of economics many other scholars have contributed to the movement which some have characterized as economic imperialism becker is one of the most outstanding of the imperialists this review of his work is organized in accordance with the main topics on which becker has worked chronologically his work on the economics of discrimination which grew out of his doctoral dissertation comes first next in order come his fundamental contributions to human capital theory he was also one of the founders of the so called new theory of consumption which is no longer so new and he has made important contributions to the economic study of crime and punishment and to the economics of political decision making some of his most original work is in the economics of the family where he provides economic explanations of such questions as marriage divorce and procreation after the topic by topic review of becker s contributions i will try to provide a more general evaluation of his work and to characterize it more fully in terms of research traditions and methodological attitudes

group decision making with uncertain outcomes unpacking child parent choice of the high school track predicting group decisions under uncertainty requires disentangling individual members utilities over the consequences of choice their expectations for uncertain outcomes and their choice process as a group i estimate simple bayesian models of child parent choice of high school track with subjective risk and unilateral or bilateral nonstrategic decisions by combining families actual choices with novel survey information about children s and parents subjective probabilities over choice consequences their individually preferred choices and their decision roles a set of policy counterfactuals confirms the importance of introducing the beliefs and decision roles of individual members in models and policy analysis of group decisions

changes in the returns to education in costa rica abstract i document patterns in the returns to education in costa rica from 1976 to 1992 the most important change during this period was that from the late 1970s to the mid 1980s the return to education fell by about one fourth i construct demand and supply indices within a fixed manpower requirements framework to estimate demand and supply shifts i find a significantly positive relationship between measures of demand for education and a significantly negative relationship between measures of supply for education these findings suggest that calculations based on the returns to education such as the returns to social investments in education must take into account future changes in the returns to education as supply and demand conditions develop

incentives allocation and labour market reforms during transition the case of urban china 1986 1990 has the reform process in china resulted in the introduction of incentives directed at a more efficient allocation of resources using data on individual earnings in urban liaoning province for the period 1986 1990 and a wage equation approach we address this issue in the context of labour market reforms focusing specifically on returns to education our results indicate that failure to address the issue of endogenous selection of more able individuals into state owned enterprises soes can severely bias returns downwards unlike in soes returns in collective owned enterprises coes increased the latter having been allowed to grow out of the plan more quickly and subject to more competition in factor and product markets we conclude that decentralization without competition is unlikely to result in the introduction of an efficient incentive mechanism the more administratively determined regular wages are one avenue for increased returns we find evidence of differentiated bonuses in coes but

the schooling decision family preferences intergenerational conflict and moral hazard in the brazilian favelas this paper experimentally analyzes the schooling decisions of poor households in urban brazil we elicit parents choices between monthly government transfers conditional on their adolescent child attending school and guaranteed unconditional transfers of varying sizes in the baseline treatment an overwhelming majority of parents prefer conditional transfers to larger unconditional transfers however few parents prefer conditional payments if they are offered text message notifications whenever their child misses school these findings suggest important intergenerational conflicts in these schooling decisions a lack of parental control and observability of school attendance and an additional rationale for conditional cash transfer programs the monitoring they provide

supply chain and logistics issues of bio energy production abstract within the concert of renewable energy technologies bio energy can play a decisive role during the next decades when smartly designed and applied under favorable conditions in this respect efficient and effective supply chain and logistics management represent one key parameter this paper presents a literature review of articles published in english speaking peer reviewed journals from 2000 to 2009 which cover the interface of bio energy production and issues of logistics and supply chain management first the articles are assessed according to descriptive criteria such as journal year of publication and research design applied then issues and challenges of designing and operating biomass chains that secure stable and competitively priced feedstock supply for bio energy plants have been classified 1 into the operations harvesting and collection storage transport and pre treatment techniques as well as 2 into overall supply system design although biomass supply chains for energy use are manifold in terms of size design and functioning most relevant issues regarding supply chain management and logistics of bio energy production are identified the findings are discussed against the backdrop of bio energy as sustainable renewable energy option

asymmetries in the union wage premium in ghana the article uses a matched employer employee data set for ghana and adopts a quantile regression approach that allows the effects of unionization to vary across the conditional wage distribution it is shown that if there are intrafirm differences in unionization there does appear to be a premium among poorer paid workers in the formal sector although this cannot be given a causal interpretation it suggests important issues about how unions may affect one part of the labor market

bio energy policies in a global context abstract against the background of an increasing global demand for bio energy the need for sustainability standards and a certification system ensuring sustainable production and trade has grown rapidly nevertheless there is currently no specific forum for discussions on how to deal with biomass trade at the multilateral level distortions in agricultural and energy trade regimes the myriad of standards and the lack of a clear biomass classification in the multilateral trade regime suggest that bio energy products may not deliver sustainable development gains for all trading partners this paper analyses then the global impact of bio energy policies on biomass production and trade paying particular attention to sustainable development in the bio energy sector it examines how a possible reduction and elimination of trade barriers as well as a phasing out of trade distorting support measures would contribute to the development of a global sustainable bio energy market

poverty and the political economy of public education spending evidence from brazil a large body of literature has emphasized the elite capture of democratic institutions as the explanation for the low levels of spending on public education in many low income democracies this paper provides an alternative to that longstanding hypothesis motivated by new cross country facts and evidence from brazilian municipalities we hypothesize that many democratic developing countries might invest less in public education spending because poor decisive voters prefer the government to allocate resources elsewhere one possible explanation is that low income voters could instead favor redistributive programs that increase their incomes in the short run such as cash transfers to test for this possibility we design and implement an experimental survey and an incentivized choice experiment in brazil the findings from both interventions support our hypothesis

heterogeneity in returns to schooling econometric evidence from ethiopia this paper investigates whether returns to schooling in ethiopia vary across the wage distribution of individuals to do so it adopts an instrumental variables quantile regression framework that allows for both endogeneity of schooling resulting from unmeasured ability and possible heterogeneity in the impact of schooling the empirical estimates indicate that education contributes more to the earnings of individuals at a lower end of the income distribution

parent child bargaining parental transfers and the post secondary education decision schooling decisions are often modelled within a unitary preference framework in this article an alternative to the unitary preference model is proposed in which parents and child have conflicting preferences over parental transfers and the level of post secondary schooling and participate in cooperative bargaining as a means of resolving this conflict comparisons of the implications of the bargaining and unitary preference models motivate tests of parental altruism and income pooling to test these hypotheses reduced form transfer and schooling equations are estimated using data from the high school and beyond surveys the evidence suggests that the unitary preference model be rejected

school markets the impact of information approximating schools effectiveness abstract the impact of competition on school performance is likely to depend on whether parents are informed about schools effectiveness or value added which may or may not be correlated with absolute measures of their quality and on whether this information influences their school choices thereby affecting schools market outcomes this paper explores this by considering chile s sned program which seeks to identify effective schools selecting them from homogeneous groups of comparable institutions its results are widely disseminated and the information it generates is different from that conveyed by a simple test based ranking of schools which turns out to approximate a ranking based on socioeconomic status we use a sharp regression discontinuity to estimate the effect that being identified as a sned winner has on schools enrollment tuition levels and socioeconomic composition through five applications of the program we find no consistent evidence that winning a sned award affects these outcomes

child control in education decisions an evaluation of targeted incentives to learn in india i report the results of a field experiment in gurgaon india that offered cash and noncash incentives to learn either to children or to their parents while i find no evidence that the identity of the recipient or form of the reward mattered in the aggregate noncash incentives targeted to children were more effective for initially low performing children while cash incentives were more effective for high performing children to explore the mechanisms behind this result i present a model of household education production and find additional empirical results consistent with the model

european union leadership in biofuels regulation europe as a normative power the rapid emergence of the european union eu as a leader in global environmental politics has led many scholars to argue in favour of the eu being a normative power in international relations this paper critically examines the eu s biofuels policy and evaluates whether its attempts to lead by example and shape international practice in this field could support such arguments europe s biofuel policies are evaluated through a sustainable development lens so as to determine the extent to which it has embraced a holistic approach to sustainability while not dismissing that the identity of the eu is indeed an explanatory factor and that normative intentions may well be regarded as a motivating force this study argues that an interest based perspective on international environmental regulation offers a supplementary view of how an actor s preferences for an international regime are shaped by erecting barriers aimed at shielding its own inefficient domestic biofuels production the eu is in essence placing trade competitiveness and economic growth above environmental protection thus permitting sustainability concerns to be addressed only in part

integrated assessment of sustainability trade offs and pathways for global bioenergy production framing a novel hybrid approach abstract current controversies and debates on bioenergy production in the areas of greenhouse gases emission reduction food and energy security social exclusion and welfare erosion and ecosystem deterioration attest to the challenges which the bioenergy sector has to overcome to achieve its global production potentials because it is yet an evolving sector the sustainability of bioenergy production in different regions is very elusive experiences show that bioenergy policies in one region can have impacts not only on its own but also on other regions social economic and ecological sustainability it is thus important to assess development pathways for bioenergy to exploit the potential benefits and forestall any unnecessary costs this paper frames a novel hybrid approach for assessing bioenergy potentials for regions with diverging economic social and ecological systems the approach is based on a conceptual framework that takes into account trade offs decisions on sustainability goals and production options in the assessment of bioenergy pathways it combines different empirical techniques for the systematic investigation of trade offs and pathways including fuzzy logic conjoint logit and path analyses to show the relevance and utility of these techniques for the integrated assessment of trade offs and pathways in bioenergy development we illustrated their application using results and data from previous related studies

international bioenergy trade a review of past developments in the liquid biofuel market policies aimed to promote biofuels locally had tremendous effects on global market developments across the past decade this article develops insights into the interaction of these policies and market forces via a comprehensive collection and analysis of international production and trade data it shows that world biofuel production and trade has grown exponentially from below 30 pj in 2000 to 572 pj in 2009 for biodiesel from 340 pj in 2000 to over 1540 pj in 2009 for fuel ethanol the eu has dominated world biodiesel whereas the us and brazil have led fuel ethanol production world net biofuel trade reached 120 130 pj in 2009 and was directed towards the most lucrative markets for biodiesel this has been the eu whose imports rose to 92 pj in 2008 and remained at 70 pj in 2009 regarding fuel ethanol both the us and the eu have been prime destinations for competitively priced exports the vast majority of which originated in brazil international biofuel trade is both supply and demand driven the demand side was shaped by support policies which generally increased the domestic market value of biofuels trade developed wherever these policies prices were not accompanied by respective measures it is found that import duties largely influenced trade volumes whereas trade routes were mainly driven by tariff preferences trade regimes appear to have been designed and adapted unilaterally along national interests causing market disruptions trade inefficiencies and disputes to avoid these it is important to explicitly consider international trade implications of national trade policies a prerequisite is to improve the understanding of the underlying complex and interwoven links within the market the current lack of adequate homogeneous international reporting of biofuel production and trade statistics could be bridged via internationally standardized custom clarifications trade factor interrelations also need to be investigated further

education experience and earnings in the labor market of a developing economy the case of urban khartoum abstract this paper examines the relevance of the human capital approach to explaining the variance in workers productivity and earnings in the labor market or urban khartoum the analysis produces two principal findings first the rate of return to education in sudan is relatively low compared with the rate of return in other developing countries perhaps a reflection of poor quality of education in the sudan second while returns to primary education are lower than average returns to college education are higher this creates an interesting paradox because the sudan educates a higher percentage of children at the secondary and tertiary levels than most sub saharan african countries the most likely explanation is that the emigration of skilled manpower to other arab states combined with an influx of unskilled labor into khartoum has created a situation where skilled manpower is relatively scarce the paper also examines the temporal relationship between education and the labor market and identifies how sudan s rapid expansion of the education system has led to the filtering down of the educational qualifications and job competition a process that may well stimulate dynamic growth throughout the economy

wage inequality and the distribution of education abstract this paper analyzes the relationship between education and wage inequality in metropolitan brazil the study is based on data from ten brazilian annual household surveys pnads which are available for the period 1976 1986 the universe of analysis is limited to occupied prime age males the inequality measure used was theil s second measure which is analytically convenient for a study of the determinants of inequality it is shown that there exist sharp differences in wage inequality across metropolitan areas to identify whether these large regional differences in inequality are directly associated with differences in educational levels or with differences in the steepness of the wage education profiles some simulations are conducted the results indicate that regional differences in the distribution of education are not able to explain much of the regional differences in wage inequality as a matter of fact the differences in wage inequality were shown to be intrinsically associated with differences in the steepness of the wage education profiles

credit constraints and human capital accumulation in the open economy abstract this paper analyzes the implications of capital market imperfections for understanding the causes and consequences of international trade credit constraints in financing education and exogenous income distribution affect patterns of comparative advantage and are crucial in determining the impact of international trade unlike the standard results in the trade literature in the model here trade liberalization in a skill scarce country leads to higher investments in human capital

wage structure as implicit insurance on human capital in developed versus underdeveloped countries abstract this paper explores the role of wage structure as implicit insurance on human capital it illustrates how smaller wage differentials in the developed world can be welfare enhancing by acting as implicit insurance while larger wage differentials in underdeveloped countries make investments in human capital riskier in other words with smaller wage differentials the students in a developed country are insured against poor educational outcomes through the existence of well paid alternative employments which are not present in the economy of a less developed country this result arises as multiple equilibria in a general equilibrium model when there are no insurance markets for human capital

education earnings and the canadian g i bill canadian second world war veterans benefited from an extensive educational pro gram similar to the u s g i bill because of differences in military enlistment rates how ever a much lower fraction of quebec men were eligible for these benefits than men from other provinces building on this fact we analyse inter cohort patterns of education and earnings for english speaking men from ontario using french speaking men from quebec as a control group we find that the instrumental variables estimates of the return to school ing are typically as big or bigger than the corresponding ols estimates jel classification j24 i21

the effects of generalized school choice on achievement and stratification evidence from chile s voucher program in 1981 chile introduced nationwide school choice by providing vouchers to any student wishing to attend private school as a result more than 1000 private schools entered the market and the private enrollment rate increased by 20 percentage points with greater impacts in larger more urban and wealthier communities we use this differential impact to measure the effects of unrestricted choice on educational outcomes using panel data for about 150 municipalities we find no evidence that choice improved average educational outcomes as measured by test scores repetition rates and years of schooling however we find evidence that the voucher program led to increased sorting as the bbestq public school students left for the private sector d 2005 elsevier b v all rights reserved

returns to investment in education a global update the author updates compilations of rate of return estimates to investment in education published since 1985 and discusses methodological issues surrounding those estimates some key patterns among the three main levels of education primary education continues to exhibit the highest social profitability in all world regions private returns are considerably higher than social returns because of the public subsidization of education the degree of public subsidy increases with the level of education which is regressive social and private returns at all levels generally decline by the level of a country s per capita income overall the returns to female education are higher than those to male education but at individual levels of education the pattern is more mixed the returns to the academic secondary school track are higher than the vocational track since unit cost of vocational education is much higher and the returns for those who work in the private competitive sector of the economy are higher than in the public noncompetitive sector and the returns in the self employment unregulated sector of the economy are higher than in the dependent employment sector controversies in the literature are discussed in the light of the new evidence the undisputable and universal positive correlation between education and earnings can be interpreted in many ways the causation issue on whether education really affects earnings can be answered only with experimental data generated by randomly exposing different people to various amounts of education given the fact that moral and pragmatic considerations prevent the generation of such pure data researchers have to make do with indirect inferences or natural experiments some have been attempted the author looks at the research on overeducation or surplus schooling the conclusions reinforce earlier patterns they confirm that primary education continues to be the number one investment priority in developing countries they also show that educating females is marginally more profitable than educating males that the academic secondary school curriculum is a better investment than the technical vocational tract and that the returns to education obey the same rules as investment in conventional capital that is they decline as investment is expanded
