empirical evaluation of bureaucratic models of inefficiency two separate but related strands of literature exist regarding the efficiency of public sector service provision the theoretical base developed in the bureaucratic models of supply and the methodological base developed in the operations research and economic literatures most analyses focus exclusively on either the measurement or causes of inefficiency this paper seeks to empirically test bureaucratic models of supply by drawing on the measurement literature in anticipation of the results it is found that there does exist empirical evidence supporting some of the implications of these models

energy consumption and economic development in sub sahara africa sub saharan african countries economic development is dependent on energy consumption this paper assesses total energy demand which is composed of traditional energy wood fuel and commercial energy electricity and petroleum in the central east south and west regions of sub saharan africa cross sectional time series data for 20 countries in 25 years are analyzed and the results of the study show that wood fuel accounts for 70 of energy consumption followed by petroleum with most industrial activities utilizing some form of wood fuel regression results suggest that energy demand is inversely related to the price of petroleum and industrial development but positively related to gdp population growth rate and agricultural expansion and that price elasticity is less than one the model results also show that there are regional differences in energy demand in addition the interaction of population growth rates by regions generates mixed results and there are regional differences in the use of commercial energy consumption and gdp growth the findings of this study suggest that countries must diversify their energy sources and introduce energy efficient devices and equipment at all levels of the economy to improve gdp growth rate and gdp per capita

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

do limits matter evidence on the effects of tax limitations on student performance abstract the goal of this research is to determine if limits on the revenue raising ability of school districts translate into constraints on the ability of these districts to affect student performance we use the recent imposition of property tax limitations on school districts in the chicago metropolitan area to determine if these limits have translated into slower growth in student performance we find only limited evidence that student performance in districts subject to the tax limitations has fallen relative to student performance in districts not subject to the limitations

budget constrained frontier measures of fiscal equality and efficiency in schooling equality and efficiency are key issues in educational reform here the authors analyze the efficiency and equality consequences of various school finance reforms using a cost indirect output distance function this function readily models multiple output production under conditions of budgetary constraint and provides a natural measure of performance that is closely related to farrell type measures of efficiency the analysis suggests that despite school district inefficiency finance reforms can affect student achievement however any potential gains in output from redistribution are dwarfed by the potential gains from increased efficiency more strikingly the analysis demonstrates that budgetary reforms designed to equalize expenditures could actually increase the inequality of student achievement

uncertainty and growth of the firm using data from a survey of 1 097 small and medium sized non listed dutch firms we investigate the relation between growth of the firm and uncertainty we focus on the impact of sales uncertainty on various types of investment we find that sales uncertainty measured by the conditional variance has a mixed impact on various investment decisions we include an analysis of the relevance of financial structure and firm size on the growth uncertainty relation

caveat emptor cross country data on education and the labor force abstract cross country data on education and the labor force frequently are used to describe important dimensions of development and to estimate models of economic growth and growth determinants the impact of education and related phenomena this investigation finds 1 there are serious intertemporal and inter country comparability problems with these data that may importantly affect inferences about labor force size trends and productivity and schooling investments and impact 2 data gaps are systematically related to levels of development and literacy and 3 conclusions about the determinants or consequences of development based on constructed data that have been made available to fill data gaps can be seriously misleading

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

measuring the distribution of material well being u s trends abstract economists with a few exceptions have automatically assumed that the important measure of well being is income in contrast economic historians have broadened the measure of well being with particular interest in mortality morbidity nutrition education and leisure when one takes this broader view of the standard of living there appears to be a strong trend toward more equality in the distribution of well being since the industrial revolution gini coefficients calculated for the distributions of lifespan and educational attainment have declined dramatically since the mid nineteenth century for the united states mortality and educational differentials have also declined inequality of leisure time and consumption though not as consistently measured also show trends toward equality over the twentieth century these trends toward equality in well being as measured by indicators other than income and wealth seem to be generated by provision of public goods natural boundaries to lifespan educational attainment and leisure and by the growth in mean per capita income the divergent trends in the distributions of income and the other measures of well being caution against reliance on the distribution of income to interpret trends in inequality

determinants of firms investment behaviour a multilevel approach this article investigates the determinants of firms investment behaviour using firm data from 101 developing and emerging economies a substantial number of firms does not invest in fixed capital or invests little relative to sales revenue using a multilevel probit model we study what factors trigger investment and using a multilevel heckman selection model we study what factors influence a firm s investment to sales ratio we find that firms investment behaviour has relatively little dependency on a country s macroeconomic setting additionally we find that on average firms that are completely foreign owned have a relatively lower investment to sales ratio finally we find evidence which suggests that the probability of investing is higher for firms located in countries with more control of corruption and we find some evidence which suggests that partially foreign owned firms located in countries with relatively less corruption have a relatively higher investment to sales ratio

an economic model of teaching effectiveness the literature on the determinants of good teaching performance has been largely devoted to empirical measurement a complete review of the publications in this area would require at least an entire issue the size of this journal yet it is virtually impossible to discover attempts to derive hypotheses about the determinants of good teaching from explicit models of behavior this has led researchers into the trap of exploring only the empirical determinants of good teaching performance typically the results of student evaluations are correlated with affective personality traits of the teachers with peer evaluations of psychological compositions or even with the results of various psychological tests examples are the works of robert isaacson et al frank costin et al and wilbert mckeachie et al in most of these studies no substantive conclusions are reached regarding the determinants of effective teaching in the few studies which do contain significant findings the independent variable in question is difficult to explain as a direct determinant of teaching effectiveness for example isaacson et al find that virtually the only statistically significant determinant of effective teaching is the personality characteristic which they label culture this may imply that simply wearing a tweed jacket and taking up pipesmoking is sufficient to improve teaching this paper takes a somewhat different approach to the analysis of teaching assume that the individual in question wishes to maximize teaching effectiveness clearly there are constraints on this maximization process one must necessarily be the time budget constraint a second constraint however adds a good deal of interest to the model this constraint is best described as the bundle of characteristics available to the individual these characteristics could be termed the components of the individual s personality such attributes include physical appearance psychological makeup speaking ability and a myriad of other variables thus this model bears a resemblance to the standard economic models of monopolistic competition see a michael spence before proceeding to a formal statement of the problem a philosophical issue must be addressed what is meant by teaching effectiveness generally this is interpreted as maximizing student evaluations of teachers however this is clearly not always equivalent to maximizing student learning unfortunately the latter variable is difficult but not impossible to measure preand posttesting with standardized tests is becoming increasingly accepted for example the meaning of teaching effectiveness in this paper must unfortunately remain ambiguous some teachers concerned perhaps with obtaining tenure will interpret good teaching as obtaining good evaluations the criterion by which they are judged others may take a more eclectic viewpoint since the problem below is an individual maximization problem the precise definition of effective teaching may simply vary from individual to individual see w r allen formally this problem is exactly analogous to one first addressed by kelvin lancaster he assumes that the consumer attempts to maximize satisfaction through purchase of bundles of attributes each commodity is possessed of certain of these characteristics by consuming various combinations of these commodities the consumer is assistant professor department of economics and director center for economic education california state university hayward i would like to thank alex cassuto nancy sanders and an anonymous referee for helpful discussion in a previously unreported experiment in the department of economics california state universitybakersfield faculty members were required to wear coats and ties in classes it was subsequently observed that teaching evaluations improved unfortunately no detailed statistical results of this experiment are available for analysis

production and innovation when techniques are tacit the case of education abstract the central theme of this paper is that the conventional economic theory of production does not hold even approximately in a field like education after examining the result of input output studies in education and the effect of government attempts to enhance education effectiveness we provide a sketch of a new production theory for sectors where techniques are poorly articulated and idiosyncratic

modeling multiple outputs in educational production functions for some time now economists have conceptualized learning as a production process most educational production functions specify only one output usually a measure of cognitive achievement some recent studies have recognized the multidimensional aspects of schooling specifying outputs in both the cognitive and affective domains introducing multiple outputs into the production function raises interesting theoretical and empirical issues one issue is the manner in which various outputs are interrelated how one models output interactions in educational production functions may be important are the outputs multiple products if so are they independently or simultaneously produced or are the outputs joint products answers to these questions may affect empirical estimates of the educational production function s this paper briefly describes how one might approach this problem we argue on conceptual grounds that modeling outputs in the cognitive and affective domains as joint products is preferable in addition we compare the three approaches empirically to evaluate the sensitivity of educational production function parameter estimates to output specification

institutions foreign direct investment and domestic investment crowding out or crowding in studies of the relationship between fdi and domestic investment reach contradictory findings we argue that some of the conflicting evidence may be explained by the use of poor proxies for the theoretical concepts and questionable methodological choices we review the paper of morrissey and udomkerdmonkol published in this journal in 2012 improvements in the construction of the proxies and refinements in the estimation methodology reverse the finding of morrissey and udomkerdmonkol that fdi inflows crowd out domestic investment furthermore there is no strong evidence that good governance actually encourages domestic investment

foreign direct investment spillovers and productivity growth in indonesian garment and electronics manufacturing inflows of foreign direct investment generate externalities that spill over to domestic firms and raise their productivity this article examines the extent of spillover effects of foreign direct investment for firms in the highly disaggregated garment isic 3221 and electronics industries isic 3832 in indonesia both are export intensive industries but differ greatly in technological sophistication and labour intensity changes in both the productivity level and rate of growth in each industry are decomposed into the effects of technological change technical efficiency change and scale efficiency change and then the impacts of spillovers on each component and on total productivity are estimated the findings suggest that foreign direct investment generates a positive effect on total productivity change technical efficiency change technological change and scale efficiency change in the garment industry in contrast foreign direct investment contributes significantly negatively to total productivity technological change and scale efficiency change but has no significant effect on technical efficiency change in the electronics industry

partial fiscal decentralization reforms and educational outcomes a difference in differences analysis for spain abstract several arguments derived from fiscal federalism theory suggest that decentralization may improve the provision of public goods and services however theory remains inconclusive regarding these effects under partial decentralization the aim of this study is to examine this hypothesis by evaluating the effects on educational outcomes of the partial fiscal decentralization reform that took place in spain during the 1980s since education competences were devolved to the regions at different points in time we can consistently estimate the effects of this reform by applying the differences in differences method and by using the non decentralized regions as the comparison group we find that the reform had a sizeable impact on the percentage of students dropping out early from school the effects are much stronger for regions with a high level of revenues we also find that the effects are concentrated in the high school program and that the reform was not able to improve educational outcomes in the vocational program we interpret these results as evidence that decentralization improved the match between education policy and population preferences

schools and housing markets an examination of school segregation and performance in connecticut this paper estimates a dynamic model of price level school performance and school racial and ethnic composition in the state of connecticut the paper finds that increasing minority representation in a labor market area reinforces the existing pattern of school segregation changes in segregation appear to be influenced by demographic trends in urban areas and by the labour market factors that determine those trends there is no evidence however to suggest that this process affects housing prices rather the housing market appears to adjust relatively quickly

the dynamic relationship between agricultural sustainability and food energy water poverty in a panel of selected sub saharan african countries abstract the relationship between food energy water resources and agricultural sustainability has got a significant policy attraction that generally in favor of livelihood of the poor which is largely affected by climate change food security challenges poor access of water resources and less access of electricity these challenges generally faced by less developing countries while sub saharan african ssa countries has no exemption to escape out from this food water energy poverty nexus due to inadequate socio economic and environmental action programs of sustainable development this study examined the dynamic nexus between agricultural sustainability and food energy water poverty in a panel of selected ssa countries over the period of 1980 2013 the study used pooled least squares regression pooled fixed effects and pooled random effects regression techniques to absorb country specific time variant shocks the hausman 1978 test results reveal that country specific shocks influence the food energy water poverty model therefore the fixed effects regression results are consider a better fit model than that of the pooled random effect model the overall results conclude that agricultural value added cereal yields and forest area significantly decreases food energy water poverty nexus leading to higher economic growth and price levels at the cost of environmental degradation in general agricultural sustainability is the prerequisite for reducing food energy water poverty

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

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

teacher training teacher quality and student achievement abstract we study the effects of various types of education and training on the productivity of teachers in promoting student achievement previous studies on the subject have been hampered by inadequate measures of teacher training and difficulties in addressing the non random selection of teachers to students and of teachers to training we address these issues by estimating models that include detailed measures of pre service and in service training a rich set of time varying covariates and student teacher and school fixed effects we find that elementary and middle school teacher productivity increases with experience informal on the job training the largest gains from experience occur in the first few years but we find continuing gains beyond the first five years of a teacher s career in contrast we do not find a consistent relationship between formal professional development training and teacher productivity however this may be partly driven by estimation issues as we find more significant positive effects of formal training in the subject grade combination where estimates should be most precise middle school math there is no evidence that teachers pre service undergraduate training or college entrance exam scores are related to productivity

renewable and non renewable energy consumption and economic activities further evidence from oecd countries this article examines the dynamic relationship between renewable and non renewable energy consumption and industrial output and gdp growth in oecd countries using data over the period of 1980 2011 the panel cointegration technique allowing structural breaks is used for empirical investigation the results show that there is a long term equilibrium relationship among non renewable and renewable energy sources industrial output and economic growth the panel causality analyses show bidirectional causality between industrial output and both renewable and non renewable energy consumption in the short and long run however there is evidence of bidirectional short run relationship between gdp growth and non renewable energy consumption while unidirectional causality between gdp growth and renewable energy consumption these results indicate that oecd economies still remain energy dependent for their industrial output as well as overall economic growth however expansion of renewable energy sources is a viable solution for addressing energy security and climate change issues and gradually substituting renewable to non renewable energy sources could enhance a sustainable energy economy

anticipating the consequences of school reform a new use of dea we use dea type linear programming techniques to simulate a basic component of educational reform eliminating restrictions on the allocation of school personnel our technique allows us to identify potential output gains or equivalently potential cost savings from reform we can also identify which personnel groups are likely to gain and lose under this reform when we apply our model to a sample of texas school districts we find evidence that the educational establishment has substantial economic rents to protect from school reform and that the primary beneficiaries of reform are likely to be affluent school districts with few minority students the technique which relies on the relationship between the direct and indirect distance functions can be easily generalized to measure the potential gains from removing other input restrictions such as union work rules environmental regulations or deed restrictions

causal effects in education abstract in recent years a wave of new studies on the effects of educational interventions on student performance has emerged the realization that inputs in the education process are endogenous is important for the validity of traditional findings because of ignoring endogeneity bias all traditional estimates might be wrong recent studies exploit exogenous variation in interventions in education produced by controlled or natural experiments results generated by this methodological innovation differ substantially from the traditional findings this article reviews this new literature illustrates new methods for identifying causal effects of interventions in education and compares the findings with the traditional literature

energy poverty in rural bangladesh energy poverty is a well established concept among energy and development specialists international development organizations frequently cite energy poverty alleviation as a necessary condition to reduce income poverty several approaches used to measure energy poverty over the past 20 years have defined the energy poverty line as the minimum quantity of physical energy needed to perform such basic tasks as cooking and lighting this paper uses a demand based approach to define the energy poverty line as the threshold point at which energy consumption begins to rise with increases in household income at or below this threshold point households consume a bare minimum level of energy and should be considered energy poor this approach was applied using cross sectional data from a comprehensive 2004 household survey representative of rural bangladesh the findings suggest that some 58 percent of rural households in bangladesh are energy poor versus 45 percent that are income poor the findings also suggest that policies to support rural electrification and greater use of improved biomass stoves might play a significant role in reducing energy poverty

recent trends in the size distribution of household wealth based on the survey of consumer finances the distribution of wealth in the united states became much more unequal in the 1980s and that trend continued albeit at a slower pace in the 1990s the only households that saw their mean net worth rise in absolute terms between 1983 and 1995 were those in the top 20 percent and the gains were particularly strong for the top one percent all other groups were particularly strong for the top one percent all other groups suffered real wealth losses including the median household and declines were particularly precipitous at the bottom racial disparities widened and young households also lost out over this period

the economics of schooling production and efficiency in public schools n recent years public and professional interest in schools has been heightened by a spate of reports many of them critical of current school policy these policy documents have added to persistent and long standing concerns about the cost effectiveness and fairness of the current school structure and have made schooling once again a serious public issue as in the past however any renewed interest in education is likely to be short lived doomed to dissipate as frustration over the inability of policy to improve school practice sets in this frustration about school policy relates directly to knowledge about the educational production process and in turn to underlying research on schools although the educational process has been extensively researched clear policy prescriptions flowing from this research have been difficult to derive 2 there exists however a consistency to the research findings that does have an immediate application to school policy schools differ dramatically in quality

school decentralization helping the good get better but leaving the poor behind abstract the decentralization of public services is a major feature of institutional innovation the main argument in support of decentralization is that it brings decisions closer to the people thereby alleviating information asymmetries and improving accountability however decentralization can also degrade service provision in poor communities that lack the ability to voice and defend their preferences in this paper we analyze the average and distributional effects of school decentralization on educational quality in argentina we find that decentralization had an overall positive impact on student test scores the decentralization gains however did not reach the poor thus although bringing decisions closer to the people may help the good get better the already disadvantaged may not receive these benefits

energy for sustainable development a case of developing countries abstract today there are 1 4 billion people around the world that lack access to electricity some 85 of them in rural areas without additional dedicated policies by 2030 the number of people drops but only to 1 2 billion some 15 of the world s population still lack access the majority of them living in sub saharan africa the number of people relying on the traditional use of biomass is projected to rise from 2 7 billion today to 2 8 billion in 2030 addressing these inequities depends upon international recognition that the projected situation is intolerable a commitment to effect the necessary change and setting targets and indicators to monitor progress a new financial institutional and technological framework is required as is capacity building in order to dramatically scale up access to modern energy services at the local and regional levels in this paper we discussed the energy situation of the developing countries for sustainable development

tax limits and the qualifications of new teachers abstract this paper examines the impact of local tax limits on new teacher quality using data from the national center for education statistics we find that tax limits systematically reduce the average quality of education majors as well as new public school teachers in states that have passed these limits the average relative test scores of education majors in tax limit states declined by ten percent as compared to the relative test scores of education majors in states that did not pass limits this relationship is strengthened if we control for school finance equalization reforms or examine tax limits passed in two different periods

firms investment decisions in response to demand and price uncertainty we investigate the effect of demand and price uncertainty on firms planned and realized investment from a panel of manufacturing firms uncertainty measures are derived from firms own expectations about demand and prices and firm s sales we find that demand uncertainty at the time of planning depresses planned and subsequent realized investment firms do not revise their plans due to demand uncertainty at the time of spending suggesting that reducing demand uncertainty will only have lagged effects on investment we do not find any effect of price uncertainty our results are consistent with the behaviour of monopolistic firms with irreversible capital

dollars and performance treating alcohol misuse in maine abstract if public funds are allocated efficiently then an increase in funding should improve the performance of substance abuse treatment programs in the data used in this paper performance measured as abstinence rates and expenditures per patient are not positively correlated one explanation is that funding is endogeneous i e programs treating more difficult patients receive more funding the data comes from all maine s outpatient drug free programs that received public funding between 1991 and 1994 after controlling for endogeneity this paper concludes that the marginal impact of expenditures per patient on abstinence rates is small and statistically insignificantly different from zero

the effect on black white wage differences of differences in the quantity and quality of education using data from the national longitudinal survey of youth for the years 1979 88 the author examines the extent to which black white differences in educational attainment educational quality and unmeasured individual ability can explain black white wage differences an analysis that corrects for both selectivity and ability biases inherent in estimating the education wage relationship shows that the main source of the black white wage differential is the racial difference in the quality rather than quantity of schooling in fact the author concludes closing the racial gap in the basic skills learned in school could reduce the wage differential by two thirds

intergenerational transfers production and income distribution abstract we consider an overlapping generations economy where the aggregative production process uses physical capital and human capital intergenerational transfers from parents to their children are motivated by altruism we distinguish between two types of transfers investment of parents in the education of their offspring and capital transfer the gift bequest motive we show that the intensity of each type of altruism and hence the composition of the two types of transfers affect significantly the equilibrium output and the intragenerational income distributions comparing competitive equilibria from the same initial distributions of capital transfers and human capital we derive a the economy with the higher education inclined altruism attains lower output and more equal intragenerational income distributions if either the production function s elasticity of substitution is not large or the altruism is weak b for more bequest inclined altruism the effects are usually reversed c under public provision of education higher bequest inclined altruism results in lower output and less equal distribution of income in all dates

the unequal work day a long term view i investigate how the distribution of daily hours worked among prime aged men has changed since the 1890s by occupational and industrial group and by the hourly wage i find that although hours of work have fallen for all workers the decline was disproportionately large among the lowest paid workers in the past hours worked were very unevenly distributed with the lowest paid workers working the longest day whereas today it is the highest paid workers who work the longest day i argue that much of the change in the relative length of the work day can be accounted for by changes in the number of daily hours workers are willing to supply i show that the unequal distribution of work hours in the past equalized income and that in recent times the unequal distribution of hours worked magnifies income disparities suggesting that wage or wealth data may underestimate long run improvements in the welfare of the lowest paid workers this abstract was borrowed from another version of this item

what do we know about investment under uncertainty recent theoretical developments relating to investment under uncertainty have highlighted the importance of irreversibility for the timing of investment expenditures and their expected returns this has subsequently stimulated a growing empirical literature which examines uncertainty and threshold effects on investment behaviour this paper presents a review of this literature a variety of methods have been used to investigate the empirical implication of irreversibility in investment the majority focusing on the relationship between investment flows and proxy measures of uncertainty a general conclusion is that increased uncertainty at both aggregate and disaggregate levels leads to lower investment rates this suggests that there is an irreversibility effect under which greater uncertainty raises the value of the call option to delay a commitment to investment this effect appears to dominate any positive impact on investment arising from the fact that greater uncertability under certain circumstances increases the marginal profitability of capital the methods used raise a number of issues which call into question the reliability of the findings and these are addressed in the paper however if such irreversibility effects are present then their omission from traditional investment models casts doubt on the efficacy of such specifications jel classification d81 d92 e22

of fair markets and distributive justice the authors argue that a free market paradigm facilitates wealth creation but does little to distribute that wealth in a just manner in order to achieve the social goal of distributive justice the concept of a fair market is introduced and explored the authors then examine three drivers that can help improve the lives of all people especially the poor civil society its institutions and business after exploring the roles these drivers might play in developing fair markets we describe three enablers that serve as catalysts for change the effects of globalization the impact of technology and the emergence of entrepreneurial activity we conclude by making recommendations for establishing fair markets and provide exemplars of two firms that embody the arguments made in the article

food subsidies and poverty alleviation this paper formulates the problem of the optimal pattern of food subsidies in a general setting where the objective is to minimize a class of poverty indices within the framework of the mo dern public finance theory taking explicit account of the budget con straint and preferences and technologies the authors derive rules fo r retargetting food subsidies to reduce poverty many operational rul es of thumb appear as special cases of the general results the analy sis thus provides not only the microfoundations of these operational rules but also their appropriate generalizations when the conditions under which they arise are not fulfilled copyright 1988 by royal economic society

corruption and cross border investment in emerging markets firm level evidence abstract this paper studies the joint impact of corruption on the entry mode and volume of inward foreign direct investment fdi using a unique firm level data set we find that corruption not only reduces inward fdi but also shifts the ownership structure towards joint ventures the latter finding supports the view that corruption increases the value of using a local partner to cut through the bureaucratic maze however r d intensive firms are found to favor sole ownership

urban agriculture poverty and food security empirical evidence from a sample of developing countries urban agriculture may have a role to play in addressing urban food insecurity problems which are bound to become increasingly important with the secular trend towards the urbanization of poverty and of pop ulation in developing regions our understanding of the importance nature and food security implica tions of urban agriculture is however plagued by a lack of good quality reliable data while studies based on survey data do exist for several major cities much of the evidence is still qualitative if not anec dotal using a recently created dataset bringing together comparable nationally representative house hold survey data for 15 developing or transition countries this paper analyzes in a comparative international perspective the importance of urban agriculture for the urban poor and food insecure some clear hints do come from our analysis on the one hand the potential for urban agriculture to play a sub stantial role in urban poverty and food insecurity reduction should not be overemphasised as its share in income and overall agricultural production is often quite limited on the other hand though its role should also not be too easily dismissed particularly in much of africa and in all those countries in which agriculture provides a substantial share of income for the urban poor and for those groups of households to which it constitutes an important source of livelihoods we also find fairly consistent evidence of a positive statistical association between engagement in urban agriculture and dietary adequacy indicators

do schools matter for high math achievement evidence from the american mathematics competitions this paper uses data from the american mathematics competitions to examine the rates at which different high schools produce high achieving math students there are large differences in the frequency with which students from seemingly similar schools reach high achievement levels the distribution of unexplained school effects includes a thick tail of schools that produce many more high achieving students than is typical several additional analyses suggest that the differences are not primarily due to unobserved differences in student characteristics the differences are persistent across time suggesting that differences in the effectiveness of educational programs are not primarily due to direct peer effects

the impact of food inflation on urban poverty and its monetary cost some back of the envelope calculations this paper uses a sample of 73 developing countries to estimate the change in the cost of alleviating urban poverty brought about by the recent increase in food prices this cost is approximated by the change in the poverty deficit that is the variation in financial resources required to eliminate poverty under perfect targeting the results show that for most countries the cost represents less than 0 1 percent of gross domestic product however in the most severely affected it may exceed 3 percent in all countries the change in the poverty deficit is mostly due to the negative real income effect of those households that were poor before the price shock while the cost attributable to new households falling into poverty is negligible thus in countries where transfer mechanisms with effective targeting already exist the most cost effective strategy would be to scale up such programs rather than designing tools to identify the new poor

on the contract curve a test of alternative models of collective bargaining the traditional model of collective bargaining confines unions to settlements constrained by the employer s labor demand curve but an alternative model places wage employment outcomes on a contract curve that extends beyond the labor demand curve this paper derives a multidimensional hedonic contract curve model in which employment security provisions are used to maintain efficient bargains outside the employer s demand curve and distinguishes empirically between the contract curve and demand constraint models using data for public school teachers in new york state estimates clearly support the contract curve model over the demand constraint model by linking the gap between compensation and the value of the marginal product to the strength of employment security provisions

human capital vs signalling explanations of wages increases wages by directly increasing the worker s productivity this learning explanation is usually associated with human capital theory however it seems unlikely that learning explains all the wage differences associated with schooling and work history better educated workers are not a random sample of workers they have lower propensities to quit or to be absent are less likely to smoke drink or use illicit drugs and are generally healthier it is unlikely that employers make full use of differences in propensities to quit or to be absent or sick when hiring workers these characteristics are often not directly observed and the americans with disabilities act precludes firms from using either poor health or the likelihood of future sickness as a hiring criterion unless it is directly related to job performance however if low levels of education are associated with these unfavorable employee characteristics and employers are allowed to take education into account when hiring workers we would expect employers to favor better educated workers as a means of reducing their costs of sickness and job turnover in turn students will take these hiring criteria into account when deciding how long to stay in school students will choose a length of schooling to signal their ability to employers and employers will demand a minimum level of schooling

democracy foreign direct investment and natural resources abstract empirical studies that examine the impact of democracy on foreign direct investment fdi assume that the relationship between democracy and fdi is the same for resource exporting and non resource exporting countries this paper examines whether natural resources in host countries alter this relationship we estimate a linear dynamic panel data model using data from 112 developing countries over the period 1982 2007 we find that democracy promotes fdi if and only if the value of the share of minerals and oil in total exports is less than some critical value we identify 90 countries where an expansion of democracy may enhance fdi and 22 countries where an increase in democratization may reduce fdi we also find that the effect of democracy on fdi depends on the size and not the type of natural resources

the impact of educational standards on the level and distribution of earnings the goal of this paper is to present the following finding an egalitarian policy maker might prefer higher standards than would a policy maker whose goal was to maximize the sum of earnings the result is based on the observation that if workers are differentiated with respect to ability an increase in educational standards will increase the earnings of both the most able and the least able workers the only workers whose earnings fall are those workers who after the increase fail to continue meeting the standard

location and education in south african cities under and after apartheid we model a south african city during apartheid in which both schooling and mobility are restricted on the basis of race and after apartheid in which no restrictions are imposed we first show that the inequality between blacks and whites decreases when apartheid laws are removed indeed blacks are better off because of human capital externalities due to the possibility of mixing with white students whereas whites are worse off due to negative human capital externalities and intensified land market competition after apartheid we also show that reducing the commuting costs of black children always increases the utility of black families and may even increase that of whites

measuring energy poverty focusing on what matters abstract the provision of modern energy services is recognised as a critical foundation for sustainable development and is central to the everyday lives of people effective policies to dramatically expand modern energy access need to be grounded in a robust information base metrics that can be used for comparative purposes and to track progress towards targets therefore represent an essential support tool this paper reviews the relevant literature and discusses the adequacy and applicability of existing instruments to measure energy poverty drawing on those insights it proposes a new composite index to measure energy poverty both the associated methodology and initial results for several african countries are discussed whereas most existing indicators and composite indices focus on assessing the access to energy or the degree of development related to energy our new index the multidimensional energy poverty index mepi focuses on the deprivation of access to modern energy services it captures both the incidence and intensity of energy poverty and provides a new tool to support policy making
