occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

distance bank heterogeneity and entry in local banking markets we examine the determinants of entry into italian local banking markets during the period 1991 2002 and build a simple model in which the probability of branching in a new market depends on the features of both the local market and the potential entrant econometric findings show that banks are more likely to expand into those markets that are closest to their pre entry locations large banks are also more able to cope with distance related entry costs than small banks finally banks have become increasingly able to open branches in distant markets due to the advent of information and communication technologies

an empirical analysis of wage dispersion and efficiency wages the main purpose of this study is to examine inter industry wage differentials in sweden after controlling for individual and job characteristics the results indicate that these differentials are substantial the ranking of the differentials was stable over time while the dispersion of wage premiums fell by 50 per cent during the period 1968 81 a period of strong efforts to reduce wage dispersion in sweden the relation between industry wage premiums and a number of industry characteristics is also examined along with new evidence which is in line with the shirking model hypothesis on the relation between wages and worker control

testing for asymmetric information in insurance markets the first goal of this paper is to provide a simple and general test of the presence of asymmetric information in contractual relationships within a competitive context we also argue that insurance data are particularly well suited to such empirical investigations to illustrate this claim we use data on contracts and accidents to investigate the extent of asymmetric information in the french market for automobile insurance using various parametric and nonparametric methods we find no evidence for the presence of asymmetric information in this market

federal lending and the market for credit abstract federal lending is an important but unrecognized feature of modern credit markets this paper analyzes the effects of credit interventions on credit allocation and economic efficiency the underlying model posits asymmetric information between borrowers and lenders and allows for market clearing rationed or redlined equilibria principal results include unsubsidized credit interventions are neutral the relative effectiveness of alternative lending instruments depends on whether rationing occurs interactions among programs can have perverse effects and even without an informational advantage the government may enact welfare improving credit policies under certain conditions

cultural distance and income divergence over time instead of featuring a long awaited convergence process the second half of the twentieth century witnessed a dramatic income divergence across countries we propose cultural distance between countries as a determinant of this economic divergence cultural similarity makes it easier for societies to interact learn and adopt from one another consequently cultural differences may lead to economic divergence over time as they slow down the adoption of technological and institutional innovations from the frontier countries we show that the overall economic divergence observed in the world since the 1950s is driven by countries with high relative cultural distance to the technological frontier in contrast the income gap among countries with low relative cultural distance remained unchanged over time further analysis reveals that a one unit rise in relative cultural distance to the frontier is associated with an increased income divergence of almost seven units

the allocation of credit and financial collapse this paper examines the allocation of credit in a market in which borrowers have greater information concerning their own riskiness than do lenders it illustrates that 1 the allocation of credit is inefficient and at times can be improved by government intervention and 2 small changes in the exogenous risk free interest rate can cause large discontinuous changes in the allocation of credit and the efficiency of the market equilibrium these conclusions suggests a role for government as the lender of last resort

adverse selection and moral hazard in insurance can dynamic data help to distinguish a standard problem of applied contracts theory is to empirically distinguish between adverse selection and moral hazard we show that dynamic insurance data allow to distinguish moral hazard from dynamic selection on unobservables in the presence of moral hazard experience rating implies negative occurrence dependence individual claim intensities decrease with the number of past claims we discuss econometric tests for the various types of data that are typically available finally we argue that dynamic data also allow to test for adverse selection even if it is based on asymmetric learning jel d82 g22 c41 c14

migration diversity and economic growth when migrants move from one country to another they carry a new range of skills and perspectives which nurture technological innovation and stimulate economic growth at the same time increased heterogeneity may undermine social cohesion create coordination and communication barriers and adversely affect economic development in this article we investigate the extent to which cultural diversity affects economic growth and whether this relation depends on the level of development of a country we use novel data on bilateral migration stocks that is the number of people living and working outside the countries of their birth over the period 1960 2010 and compute indices of fractionalization and polarization in so doing we explore the effect of immigration on development through its effect on the composition of the destination country we find that overall both indices have a distinct positive impact on real gdp per capita and that the effect of diversity seems to be more consistent in developing countries

genetic distance trade and the diffusion of development the determinants of countries long term income differences feature prominently in the literature spolaore and wacziarg the diffusion of development quarterly journal of economics 2009 124 469 529 argue that cultural differences measured by countries genetic distance are an important barrier to the diffusion of development from the world s technological frontier we revisit their findings in three ways first we successfully reproduce their results and confirm the robustness of their baseline findings second we estimate their models for different time periods and find that the impact of genetic distance on income differences did not significantly change over time finally we explore one of the underlying mechanisms of technology adoption and show that bilateral trade is one channel through which cultural differences retard the diffusion of development less

does schooling cause growth a number of economists find that growth and schooling are highly correlated across countries a model is examined in which the ability to build on the human capital of one s elders plays an important role in linking growth to schooling the model is calibrated to quantify the strength of the effect of schooling on growth by using evidence from the labor literature on mincerian returns to education the upshot is that the impact of schooling on growth explains less than one third of the empirical cross country relationship the ability of reverse causality to explain this empirical relationship is also investigated

socioeconomic background and the returns to schooling in two low income economies in the united kingdom the increment to income yielded by an additional year of schooling declines as the occupational status of the worker s father rises in this note the relationship between family background and the returns to schooling is measured in kenya and tanzania in contrast to the united kingdom a positive relationship is documented several explanations for this marked difference between a high income economy and two low income economies are suggested copyright 1987 by the review of economic studies limited

economic development and the return to human capital a smooth coefficient semiparametric approach this paper investigates the impact of human capital on the process of economic growth by allowing the contribution of traditional inputs capital and labour as well as that of human capital to vary both across countries and time the former is accomplished by constructing an index of tfp growth for traditional inputs while the latter through semiparametric methods we derive estimates of the output elasticity and social return to human capital for 51 countries at various stages of economic development copyright 2005 john wiley sons ltd

which sectors make poor countries so unproductive which sectors are most responsible for the low total factor productivities of developing countries to answer this question we develop a new framework for sectoral development accounting applying this framework to the penn world table we find that in equipment construction and food the sectoral tfp differences between developing countries and the united states are much larger than in the aggregate however in manufactured consumption the sectoral tfp differences are about equal to the aggregate tfp differences and in services they are much smaller we show that our level of disaggregation allows us to reconcile the results of existing studies of sectoral productivity differences which have focused on noncomparable two sector decompositions of the aggregate data we also show that our results help shed light on existing theories of aggregate tfp differences

growth or stagnation the role of public education abstract this paper presents a political economic theory of growth and human capital accumulation where individuals of different ages disagree over the resource commitment to public education in the context of an overlapping generations model with two period lived agents population growth implies that the equilibrium quantity of public education reflects the preferences of youth and is therefore forward looking despite forward looking behavior it is shown that sufficiently rapid population growth can trigger economic stagnation in the political economic equilibrium the model therefore offers a novel explanation for observed negative correlations between population growth measures and economic growth

education s role in china s structural transformation abstract we explore education s role in improving the allocation of labor between china s agricultural and nonagricultural sectors and measure the portion of china s recent growth attributable to this channel using detailed micro level data and an empirical model that allows for the endogenous selection of education and sector of employment we estimate the relationship between an individual s educational attainment sector and income we find that about 11 of aggregate growth in output per worker from 1978 to 2004 is accounted for by increased education with 9 coming through the labor reallocation channel and 2 attributable to increased within sector human capital

mergers with differentiated products the case of the ready to eat cereal industry traditional merger analysis is difficult to implement when evaluating mergers in industries with differentiated products i discuss an alternative which consists of demand estimation and the use of a model of postmerger conduct to simulate the competitive effects of a merger i estimate a brand level demand system for ready to eat cereal using supermarket scanner data and use the estimates to 1 recover marginal costs 2 simulate postmerger price equilibria and 3 compute welfare effects under a variety of assumptions the methodology is applied to five mergers two of which occurred and for which i compare predicted to actual outcomes

human capital and growth abstract this paper describes a growth model with the property that human capital accumulation can account for all observed growth the model is shown to be consistent with evidence on individual productivities as measured by census earnings data the central hypothesis is that we learn more when we interact with more productive people

contractual structure and wealth accumulation can historical wealth distributions affect long run output and inequality despite rational saving convex technology and no externalities we consider a model of equilibrium short period financial contracts where poor agents face credit constraints owing to moral hazard and limited liability if agents have no bargaining power poor agents have no incentive to save poverty traps emerge and agents are polarized into two classes with no interclass mobility if instead agents have all the bargaining power strong saving incentives are generated the wealth of poor and rich agents alike drift upward indefinitely and history does not matter eventually d31 d91 i32 o17 q15

endogenous matching and the empirical determinants of contract form empirical work on contracts typically regresses contract choice on observed principal and agent characteristics if i some of these characteristics are unobserved or partially observed and ii there are incentives whereby particular types of agents end up contracting with particular types of principals estimated coefficients on the observed characteristics may be misleading we address this endogenous matching problem using a data set on agricultural contracts between landlords and tenants in early renaissance tuscany controlling for endogenous matching has an impact on parameters of interest and tenants risk aversion appears to have influenced contract choice

is infrastructure capital productive a dynamic heterogeneous approach this paper offers an empirical evaluation of the output contribution of infrastructure drawing from a large data set on infrastructure stocks covering 88 countries and spanning the years 1960 2000 and using a panel time series approach the paper estimates a long run aggregate production function relating gdp to human capital physical capital and a synthetic measure of infrastructure given by the first principal component of infrastructure endowments in transport power and telecommunications tests of the cointegration rank allowing it to vary across countries reveal a common rank with a single cointegrating vector which is taken to represent the long run production function estimation of its parameters is performed using the pooled mean group estimator which allows for unrestricted short run parameter heterogeneity across countries while imposing the testable restriction of long run parameter homogeneity the long run elasticity of output with respect to the synthetic infrastructure index ranges between 0 07 and 0 10 the estimates are highly significant both statistically and economically and robust to alternative dynamic specifications and infrastructure measures there is little evidence of long run parameter heterogeneity across countries whether heterogeneity is unconditional or conditional on their level of development population size or infrastructure endowments

iq in the production function evidence from immigrant earnings the cross country growth literature especially sala i martin 1997 sala i martin doppelhofer and miller 2004 has found that traditional education measures rarely have a robust relationship with growth and productivity elementary education being a rare exception by contrast a new empirical growth literature jones and schneider 2006 lynn and vanhanen 2002 ram 2007 weede 2004 weede and kampf 2002 has shown that a nation s average iq has a remarkably robust relationship with its productivity figure 1 that a test designed by psychologists should have such a robust relationship with economic variables is a puzzle that demands explanation for instance jones and schneider showed that national average iq was more robust than other human capital variables and was statistically significant at the 1 level in all 455 growth regressions that controlled for all 18 factors that passed sala i martin doppelhofer and miller s 2004 robustness tests of course as with all the growth regression literature a key difficulty is disentangling cause and effect thus in this article we run no growth regressions whatsoever instead we perform a simple calibration of the iq productivity relationship based on widely agreed upon microeconomic parameters that means we can directly estimate one causal channel running from cognitive ability to productivity in the process we learn the following 1 if one knows the average iq of a nation s citizens as estimated by lynn and vanhanen 2002 2006 one can predict the average wages that immigrants from that country will earn upon their arrival in the united states whether or not one controls for immigrant education and even if the test is completely visual rather than verbal in other words national average iq predicts part of what hendricks 2002 calls unmeasured worker skill 2 we find that a 1 point increase in national average iq predicts 1 higher immigrant wages precisely the value found repeatedly in microeconometric studies note that by construction 1 iq point approximately equal to 1 15th of a standard deviation within any large national population together points 1 and 2 provide further evidence that cross country iq tests are valid predictors of worker productivity 3 when iq is added to the production function in the form implied by traditional externality free human capital theory differences in national average iq are quantitatively significant in explaining cross country income differences that said our productivity accounting exercise does not resolve the puzzle of why high iq countries are 15 times richer than low iq countries in a related vein hanushek and kimko 2000 use national math and science test scores to verify that cognitive skills appear to matter more for groups than for individuals like us they use immigrants to the united states as a way to test whether immigrants bring their home country productivity levels along with them when they immigrate to the united states when they interpret their results within a solow type framework they conclude that the cross country growth equation results are much larger than the corresponding results for individual earnings in sum our article rigorously explores the quantitative magnitude of the puzzle uncovered by hanushek and kimko 2000 and hanushek and woessman 2007 but by using iq tests rather than other widely used math and science test scores we can often double our sample size while simultaneously using the most widely analyzed best understood form of cognitive test we begin with an overview of the recent psychological literature on the validity of iq tests and then proceed to our discussion of the link between iq and immigrant wages the discussion of iq and immigrant wages yields a key parameter gamma the iq semi elasticity of wages which we use in our development accounting exercise we then discuss the questions of reverse causality and trends in the iq productivity relationship over the past 40 yr and conclude by discussing how our results fit into the growth literature

human capital accumulation and endogenous public expenditures in this paper we present an overlapping generations model where individuals accu mulate human capital through formal schooling we model the role of the public sector in schooling as one of collecting taxes from households and providing inputs to the learning technology public expenditures on schools are determined endogenously under plausible restrictions our model s predictions qualitatively match the observations on schooling pub lic expenditures on education and student teacher ratios jel classification el 3 e62 accumulation de capital humain et depenses publiques endogenes dans ce memoire les auteurs presentent un modele de generations qui se chevauchent ofu les individus accumulent du capital humain via l education formelle le r6le du secteur public dans l education est defini comme celui de collecteur d imp6ts aupres des menages et de fournisseur d intrants dans la technologie d apprentissage les depenses publiques en education sont determinees de maniere endogene a partir de restrictions plausibles les predictions du modele s arriment qualitativement aux observations sur le monde scolaire aux depenses publiques en educa tion et aux ratios 6leves enseignants

informational frictions and the credit crunch in this paper i estimate the magnitude of an informational friction limiting credit reallocation to firms during the 2007 to 2009 financial crisis because lenders rely on private information when deciding which relationship to end borrowers looking for a new lender are adversely selected i show how to separately identify private information from information common to all lenders but unobservable to the econometrician by using bank shocks within a discrete choice model of relationships quantitatively these informational frictions appear to be too small to explain the credit crunch in the u s syndicated corporate loan market

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

the impact of education on subjective discount rate in ugandan villages abstract heterogeneity in time discounting may reinforce the existing barriers to save and invest faced by rural populations in developing countries we elicit a subjective discount rate for a varied sample of ugandan villagers in accordance with other studies we have found the discount rate to decrease with education we examine this correlation further by testing the causal effect of education and exploit two different sources of its variation school frequency across villages and the number of the respondents school going years that overlap with the era of the dictator idi amin s rule for men we find that education has a significant impact on their discount rate similar in magnitude for both types of instruments and robust to observable characteristics this finding highlights the importance of education in development

observing unobservables identifying information asymmetries with a consumer credit field experiment information asymmetries are important in theory but difficult to identify in practice we estimate the presence and importance of hidden information and hidden action problems in a consumer credit market using a new field experiment methodology we randomized 58 000 direct mail offers to former clients of a major south african lender along three dimensions i an initial offer interest rate featured on a direct mail solicitation ii a contract interest rate that was revealed only after a borrower agreed to the initial offer rate and ii a dynamic repayment incentive that was also a surprise and extended preferential pricing on future loans to borrowers who remained in good standing these three randomizations combined with complete knowledge of the lender s information set permit identification of specific types of private information problems our setup distinguishes hidden information effects from selection on the offer rate via unobservable risk and anticipated effort from hidden action effects via moral hazard in effort induced by actual contract terms we find strong evidence of moral hazard and weaker evidence of hidden information problems a rough estimate suggests that perhaps 13 to 21 of default is due to moral hazard asymmetric information thus may help explain the prevalence of credit constraints even in a market that specializes in financing high risk borrowers

how important is human capital a quantitative theory assessment of world income inequality we develop a quantitative theory of human capital investment in order to evaluate the magnitude of cross country dierences in total factor productivity tfp that explains the variation in per capita incomes across countries we build a heterogeneousagent economy with cross sectional variation in ability schooling and expenditures on schooling quality in our theory the parameters governing human capital production and random ability process have important implications for a set of cross sectional statistics mincer return variance of earnings variance of schooling and intergenerational correlation of earnings these restrictions of the theory and u s household data are used to pin down the key parameters driving the quantitative implications of the theory our main finding is that human capital accumulation strongly amplifies tfp dierences across countries in particular we find an elasticity of output per worker with respect to tfp of 2 8 a 3 fold dierence in tfp explains a 20 fold dierence in output per worker we argue that the cross country dierences in human capital implied by the theory are consistent with a wide array of evidence including earnings of immigrants in the united states average mincer returns across countries and the relationship between average years of schooling and per capita income across countries the theory implies that using mincer returns to measure human capital understates dierences across countries by a factor of 2

microeconomic approaches to development schooling learning and growth within the field of economic development over the past 15 years or so particularly significant advances have been made in what can be loosely called micro development an area defined principally by the units that are examined not by a particular methodological approach the units may be indi viduals households networks banks government agencies and so on as opposed to countries within this area economists use a wide variety of empirical methods informed to different degrees by economic models they use data from developed and

traders teachers and tyrants democracy globalization and public investment in education this article develops a model of the redistributive political economy of education spending focusing on the role of democracy and economic openness in determining the provision of education i argue that democratization should be associated with higher levels of public education spending lower private education spending and a shift from tertiary education spending toward primary education spending furthermore i argue that integration with the international economy should lead to higher public education spending conditioned on regime type and income and should push the balance between tertiary and primary education toward states particular comparative advantages these propositions are tested on a data set of more than one hundred states from 1960 to 2000 using a variety of panel data techniques including instruments for democracy the logic of the causal mechanism developed in the formal model is also tested on a number of case histories including the philippines which shows great variation in democracy and openness and india and malaysia which constitute unusual cases that lie off the diagonal of open democracies and autarkic autocracies the author would like to thank beth simmons torben iversen michael hiscox jeffry frieden jim alt teri caraway john freeman jane gingrich david samuels w phillips shively mark kayser john ahlquist and michael kellerman for highly useful comments and criticisms in addition i thank the current and past editors lou pauly emanuel adler david stasavage and lisa martin and three anonymous reviewers for their suggestions

human capital and industrialization evidence from the age of enlightenment while human capital is a strong predictor of economic development today its importance for the industrial revolution is typically assessed as minor to resolve this puzzling contrast we differentiate average human capital worker skills from upper tail knowledge both theoretically and empirically we build a simple two sector model where worker skills raise the productivity in both agriculture and manufacturing and scientific knowledge affects the entrepreneurial ability to keep up with a rapidly advancing technological frontier the model predicts that the local presence of knowledge elites is unimportant in the pre industrial era but drives growth thereafter worker skills in contrast are not crucial for growth to measure the historical presence of knowledge elites we use city level subscriptions to the famous encyclopedie in mid 18th century france we show that subscriber density is a strong predictor of city growth after 1750 but not before the onset of french industrialization alternative measures of development confirm this pattern soldier height and industrial activity are strongly associated with subscriber density after but not before 1750 literacy on the other hand does not predict growth finally by joining data on british patents with a large french firm survey from 1837 we provide evidence for the mechanism upper tail knowledge raised the productivity in innovative industrial technology

the contribution of education to economic growth a review of the evidence with special attention and an application to sub saharan africa summary this paper examines recent studies that estimate the impact of education on economic growth it explains why cross country regressions face formidable econometric problems recent studies are reviewed some show strong impacts of education on economic growth others show little effect all have multiple estimation problems which may explain their divergent results evidence shows that education quality in sub saharan africa is much lower than in other developing countries estimates from three influential studies are extended the results suggest that the impact of education on economic growth in sub saharan africa is lower than in other countries likely due to lower school quality

too much investment a problem of asymmetric information this paper shows that under plausible assumptions the inability of lenders to discover all of the relevant characteristics of borrowers results in investment in excess of the socially efficient level raising the rate of interest above the free market level will restore optimality this conflicts with generally held views and is contrasted with the stiglitz weiss model it is shown that the assumptions which yield overinvestment support debt as the equilibrium method of finance however under the stiglitz weiss assumptions used to derive an underinvestment result equity is shown to be the equilibrium method of finance

latin america in the rearview mirror abstract latin american countries are the only western countries that are poor and that are not gaining ground on the u s this paper evaluates why latin america has not replicated western economic success we find that this failure is primarily due to tfp differences latin america s tfp gap is not plausibly accounted for by human capital differences but rather reflects inefficient production we argue that competitive barriers are a promising channel for understanding low latin tfp we document that latin america has many more international and domestic competitive barriers than do western and successful east asian countries we also document a number of microeconomic cases in latin america in which large reductions in competitive barriers increase latin american productivity to western levels

route 128 the development of a regional high technology economy abstract a corner of massachusetts not far from boston s route 128 has become a world center of high technology hundreds of enterprises mainly in electronics based industries employ over 250 000 people 75 000 of whom were added between 1975 and 1980 enterprises founded after world war ii have spearheaded growth in the state with a rapid rate of new firm formation continuing through the 1970s this paper examines the state s high tech growth to determine what caused it to happen where it did and assess the special role of new enterprises in promoting it the development is found to have been largely indigenous and spontaneous rather than the result of a concerted effort to attract industry massachusetts distinguished universities and their research laboratories an inherited technological infrastructure the importance of agglomeration externalities and the good fortune of having a home grown firm become the world s leading manufacturer of minicomputers were major contributors to the state s success but the enormous opportunities for new enterprises which the electronics revolution generated and the tendency for such firms to start up mainly as spin offs from other high tech firms or from university laboratories and to remain close to their sources fueled the tendency towards spatial concentration

cross country differences in the quality of schooling abstract this paper constructs a cross country measure of the quality of education using a novel approach based on international test scores data the first main finding is that there are large differences in education quality one year of schooling in the u s is equivalent to three or more years of schooling in a number of low income countries i incorporate the estimated series for schooling quality in an accounting framework calibrated using evidence on mincerian returns this leads to the second important finding which is that the fraction of income differences explained by the model rises substantially when one includes education quality the increase is around 22 percentage points

the slowdown in american educational attainment relative to those for high school graduates lifetime earnings for college graduates are higher for more recent cohorts at the same time across successive cohorts born after 1950 there is a stagnation in the fraction of high school graduates that go on to complete a college degree what explains this phenomenon i formulate a life cycle model of human capital accumulation in college and on the job where successive cohorts decide whether or not to acquire a college degree as well as the quality of their college education cohorts differ by the sequence of rental price per unit of human capital they face and by the distribution of initial human capital across individuals my model reproduces the observed pattern in college attainment for the 1920 1970 birth cohorts the stagnation in college attainment is due to the decrease in the growth rate of the rental price per unit of human capital commencing in the 1970s my model also generates about 80 of the increase in lifetime earnings for college graduates relative to those for high school graduates observed across cohorts

asymmetric information and imperfect competition in lending markets we study the effects of asymmetric information and imperfect competition in the market for small business lines of credit we estimate a structural model of credit demand loan use pricing and firm default using matched firm bank data from italy we find evidence of adverse selection in the form of a positive correlation between the unobserved determinants of demand for credit and default our counterfactual experiments show that while increases in adverse selection increase prices and defaults on average reducing credit supply banks market power can mitigate these negative effects

liquidity constraints and imperfect information in subprime lending ditions for precisely the population that is most likely to have a difficult time obtaining credit those with low incomes and poor credit histories these consumers who typically cannot qualify for regular bank loans comprise the so called subprime market because the company we study originates subprime loans its loan applications and transaction records provide an unusual win dow into the consumption and borrowing behavior of households that are rationed in primary credit markets moreover we track loan repayments allowing us to analyze the difficulties in lending to the subprime population we begin by documenting the importance of short term liquidity constraints for individuals in our sample we present two pieces of evidence both are based on purchasing behavior and indicate a high sensitivity to cash on hand first we document a dramatic degree of demand seasonality associated with tax rebates overall demand is almost 50 percent higher during tax rebate season than during other parts of the year this seasonal effect varies with household

economic demographic and institutional determinants of life insurance consumption across countries life insurance has become an increasingly important part of the financial sector over the past 40 years providing a range of financial services for consumers and becoming a major source of investment in the capital market but what drives the large variation in life insurance consumption across countries remains unclear using a panel with data aggregated at different frequencies for 68 economies in 1961 2000 this article finds that economic indicators such as inflation income per capita and banking sector development and religious and institutional indicators are the most robust predictors of the use of life insurance education life expectancy the young dependency ratio and the size of the social security system appear to have no robust association with life insurance consumption the results highlight the importance of price stability and banking sector development in fully realizing the savings and investment functions of life insurance in an economy

testing production functions used in empirical growth studies abstract we estimate and test alternative functional forms which have been used in the growth literature representing the aggregate production function for a panel of countries functional forms are confronted using a box cox test and results favor the mincerian formulation of schooling returns to skills

education lifetime labor supply and longevity improvements this paper presents an analysis of the differential role of mortality for the optimal schooling and retirement age when the accumulation of human capital follows the so called ben porath mechanism we set up a life cycle model of consumption and labor supply at the extensive margin that allows for endogenous human capital formation this paper makes two important contributions first we provide the conditions under which a decrease in mortality leads to a longer education period and an earlier retirement age second those conditions are decomposed into a ben porath mechanism and a lifetime human wealth effect vs the years to consume effect finally using us and swedish data for cohorts born between 1890 and 2000 we show that our model can match the empirical evidence

contract pricing in consumer credit markets we analyze subprime consumer lending and the role played by down payment requirements in screening high risk borrowers and limiting defaults to do this we develop an empirical model of the demand for financed purchases that incorporates both adverse selection and repayment incentives we estimate the model using detailed transaction level data on subprime auto loans we show how different elements of loan contracts affect the quality of the borrower pool and subsequent loan performance we also evaluate the returns to credit scoring that allows sellers to customize financing terms to individual applicants our approach shows how standard econometric tools for analyzing demand and supply under imperfect competition extend to settings in which firms care about the identity of their customers and their postpurchase behavior

cultural constraints on innovation based growth to what extent does the cultural composition of a society impose a constraint on its long run growth potential we study this question in the context of an innovation based model of growth where cultural attitudes are endogenously transmitted from one generation to the next focusing on attitudes regarding patience we analyze the two way interaction between economic growth and the intergenerational transmission of patience exploiting this interaction we compare the long run growth performance of a culturally heterogeneous society where patience is initially underrepresented in the population with a culturally homogeneous society where all agents are perfectly patient our main result is that in the absence of any intrinsic preferences of patient parents to transmit their attitudes to their children the development paths of the two societies are bound to diverge with the culturally heterogeneous society experiencing lower growth rates yet if patient parents ceteris paribus prefer their children to be patient like them we show that the two societies can in the long run grow at the same rate jel d91 e24 o30 o40 z10

multiple versus single banking relationships theory and evidence a theory of the optimal number of banking relationships is developed and tested using matched bank firm data according to the theory relationship banks may be unable to continue funding profitable projects owing to internal problems and a firm may thus have to refinance from nonrelationship banks the latter however face an adverse selection problem as they do not know the quality of the project and may refuse to lend in these circumstances multiple banking can reduce the probability of an early liquidation of the project the empirical evidence supports the predictions of the model

the optimal public expenditure financing policy does the level of economic development matter i introduction does the growth effect of public expenditures depend on the way these expenditures are financed over the years a substantial volume of theoretical and empirical research has been directed toward identifying the elements of public expenditure at its aggregated and disaggregated level that bear significant association with economic growth in contrast only a handful of studies have paid particular attention to examine the extent to which the growth effect of public expenditures depends on the method of financing such expenditures e g de gregorio 1993 miller and russek 1997 palivos and yip 1995 the consensus appears to be that the two primary modes of financing income taxation and seigniorage are distortionary opinions however are divided as to their relative merits for example according to palivos and yip 1995 income tax financing is more detrimental to growth than seigniorage financing at the same time de gregorio 1993 suggests that as long as the rate of return on indexed bonds is substantially responsive to changes in the rate of inflation seigniorage financing of public expenditure is more growth reducing pecorino 1997 on the other hand prescribes a mix of both modes of financing despite these differences the above mentioned studies share a common characteristic the optimal mode of financing public expenditure in these studies is viewed as being not contingent on the stages of economic development accordingly there remains little understanding of the process by which public expenditure financing policies shape the prospect of economic growth for developing vis a vis developed countries the primary objective of this paper is to bridge this gap in the existing literature it is a long standing belief among development experts that outcomes of public expenditures and revenue policies are conditional on the state of an economy recent evidence supports such belief for example miller and russek 1997 suggest that for developing countries a deficit financed increase in public expenditure retards economic growth and a tax financed increase leads to higher growth for developed countries a deficit financed increase in government expenditure does not affect economic growth and a tax financed increase leads to a lower growth in light of these findings and in light of the theoretical controversy about the relative merits of seigniorage versus tax finance it is meaningful to ask the following question does the relative merit of seigniorage vis a vis tax financing of public expenditure depend on the stage of economic development this paper seeks an answer to this question using both theoretical and empirical analyses the theoretical framework developed in this paper shares many of the characteristics of the models proposed by espinosa vega and yip 1999 2000 and schreft and smith 1997 in particular we consider a two period overlapping generations model where agents are subjected to stochastic relocations shocks which act like shocks to their portfolio preferences these shocks have the same consequence as liquidity preference shocks as in diamond and dybvig 1983 and create a role for financial intermediaries who take deposits and make a portfolio decision on behalf of the households in addition there is a government that relies on two alternative sources of revenue seigniorage and tax revenue to finance its exogenously given expenditure sequence the results that we derive are shaped by the portfolio decision of the financial intermediaries in particular at each point in time financial intermediaries are required to allocate their portfolios between a nonproductive liquid asset money and a productive illiquid asset the illiquid asset takes the form of financing risky investment projects which in turn generate productive capital stock for the economy the financial intermediaries optimal portfolio allocation rules depend on the relative rate of return of the two available assets

insurer pricing and consumer welfare evidence from medigap this article examines the welfare impact of imperfect competition in the medicare supplement insurance medigap market two firms control nearly three fourths of the medigap market and premiums exceed claims by over 25 i find that a low price elasticity and consumers brand preferences lead firms to engage in substantial marketing and price above cost therefore the strategic behavior of insurers facing relatively inelastic demand is critical in explaining poor market performance i also find that insurers do not capture all of the rents in this market rents also accrue to actors who perform marketing functions including agents and brokers

the medium run effects of educational expansion evidence from a large school construction program in indonesia this paper studies the medium run consequences of an increase in the rate of accumulation of human capital in a developing country from 1974 to 1978 the indonesian government built over 61 000 primary schools the school construction program led to an increase in education among individuals who were young enough to attend primary school after 1974 but not among the older cohorts 2sls estimates suggest that an increase of 10 percentage points in the proportion of primary school graduates in the labor force reduced the wages of the older cohorts by 3 8 10 and increased their formal labor force participation by 4 7 i propose a two sector model as a framework to interpret these findings the results suggest that physical capital did not adjust to the faster increase in human capital

education growth and income inequality estimates of the effect of education on gdp the social return have been hard to reconcile with micro evidence on the private return to schooling we present a simple explanation combining two ideas imperfect substitution and endogenous skill biased technological progress and use cross country panel data on inequality and gdp to test these ideas a one year increase in the level of education reduces the private return by 2 percentage points consistent with katz murphy s 1992 elasticity of substitution we find no evidence for reversal of this initial effect as in acemoglu 2002 in the short run the social return equals the private return

does local financial development matter we study the effects of differences in local financial development within an integrated financial market we construct a new indicator of financial development by estimating a regional effect on the probability that ceteris paribus a household is shut off from the credit market by using this indicator we find that financial development enhances the probability an individual starts his own business favors entry of new firms increases competition and promotes growth as predicted by theory these effects are weaker for larger firms which can more easily raise funds outside of the local area these effects are present even when we instrument our indicator with the structure of the local banking markets in 1936 which because of regulatory reasons affected the supply of credit in the following 50 years overall the results suggest local financial development is an important determinant of the economic success of an area even in an environment where there are no frictions to capital movements

factors governing the development of high tech industry agglomerations a tale of three cities glasmeier a 1988 factors governing the development of high tech industry agglomerations a tale of three cities reg studies 22 287 301 high tech industries are thought to precipitate structural change in local economies through the creation of backward and forward linkages and new firm spinoffs case studies of high tech firms and products indicate interindustry linkage development is closely associated with product type and organizational structure of firms three product configurations one of a kind customized and standardized generate differing levels of linkage and spinoff potential firms producing customized products with highly variable input structures and established subcontracting relationships are more amenable to linkage and spinoff creation than firms producing one of a kind or standardized products the potential for linked industry development is further diluted because the spatial expansion path of high tech firms has been through the creation of technical branch plants which a

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
