the geographical dimension of the development effects of natural resources we study the contribution of natural resource intensity to long term development along different dimensions per capita income institutional quality and education we allow natural resources to affect these dimensions differently in different regions of the world the evidence suggests that natural resources are generally a positive driver of development but in sub saharan africa ssa their contribution is almost negligible if not even negative we explain these cross regional differences with the fact that in ssa more than anywhere else large resource endowments are combined with a particularly bad disease environment some historical evidence and formal econometric results support this hypothesis

income inequality and colonialism this paper proposes that colonialism is a major explanation behind today s differences in income inequality across countries we argue that income inequality has been higher in the colonies where the percentage of european settlers to total population was higher as long as europeans remained a minority the countries where europeans became the majority of the population did not suffer from high inequality these initial differences continue to hold today the empirical evidence we provide strongly supports our thesis

transversality conditions budget constraints and the determinacy of a perfect foresight equilibrium in a monetary growth model the purpose of this paper is to analyze the number of perfect foresight equilibria in a monetary model where the consumer s behavior and the firm s behavior are explicitly derived from an intertemporal optimization we show that the relevant transversality conditions reduce to the satisfaction of the intertemporal budget constraint of the consumer or alternatively of the government the assumption of a separable utility function enables us to characterize completely the perfect foresight equilibria their number is shown to depend both on the specification of the government s policy instruments and on the utility function

measuring business cycles a modern perspective in the first half of this century special attention was given to two features of the business cycle 1 the comovement of many individual economic series and 2 the different behavior of the economy during expansions and contractions both of these attributes were ignored in many subsequent business cycle models which were often linear representations of a single macroeconomic aggregate however recent theoretical and empirical research has revived interest in each attribute separately notably dynamic factor models have been used to obtain a single common factor from a set of macroeconomic variables and nonlinear models have been used to describe the regime switching nature of aggregate output we survey these two strands of research and then provide some suggestive empirical analysis in an effort to unite the two literatures and to assess their usefulness in a statistical characterization of business cycle dynamics

institutions and agricultural productivity in sub saharan africa agricultural productivity in 41 sub saharan africa ssa countries from 1960 to 1999 is examined by estimating a semi nonparametric fourier production frontier over the four decades the estimated rate of productivity change was 0 83 per year although the average rate from 1985 99 was a strong 1 90 per year former uk colonies exhibited significantly higher productivity gains than others while liberia and countries that had been colonies of portugal or belgium exhibited net reductions in productivity we measure a significant reduction in productivity during political conflicts and wars and a significant increase in productivity among those countries with higher levels of political rights and civil liberties

religion and female educational attainment the paper reviews the literature on the education gender and religion nexuses and identifies plausible hypotheses that religion adversely affects female education the link between major religions and female educational attainment is examined using the barro lee data set for a sample of 97 countries the estimates include control variables for colonial heritage urbanization labor force participation and young adult mortality the estimates show powerful negative links between female educational attainment and the proportion of ethnoreligions hindu and muslim adherents in a country with similar results for the gender gap the paper offers some interpretative thoughts and research agendas

federal reserve interest rate targeting rational expectations and the term structure abstract the amount of information in the yield curve for forecasting future changes in short rates varies with the maturity of the rates involved indeed spreads between certain long and short rates appear unrelated to future changes in the short rate contrary to the rational expectations hypothesis of the term structure this paper estimates a daily model of federal reserve interest rate targeting behavior which accompanied by the maintained hypothesis of rational expectations explains the varying predictive ability of the yield curve and elucidates the link between fed policy and the term structure

historical legacies a model linking africa s past to its current underdevelopment abstract recent studies have found evidence linking africa s current under development to colonial rule and the slave trade given that these events ended long ago why do they continue to matter today i develop a model exhibiting path dependence which provides one explanation for why these past events may have lasting impacts the model has multiple equilibria one equilibrium with secure property rights and a high level of production and others with insecure property rights and low levels of production i show that external extraction when severe enough causes a society initially in the high production equilibrium to move to a low production equilibrium because of the stability of low production equilibria the society remains trapped in this suboptimal equilibrium even after the period of external extraction ends the model provides one explanation why africa s past events continue to matter today

did colonization matter for growth an empirical exploration into the historical causes of africa s underdevelopment we investigate the impact of 20th century european colonization on growth we 5nd that colonial heritage as measured by the identity of the metropolitan ruler and by the degree of economic penetration matters for the heterogeneity of growth performances in africa colonial indicators are correlated with economic and sociopolitical variables that are commonly employed to explain growth and there are growth gains from decolonization colonial indicators also add signi5cant explanatory power to worldwide growth regressions and are correlated with the sub saharan africa and the latin america dummies c

inflation and unemployment the world economy today is vastly different from the 1930s when seymour harris the chairman of this meeting infected me with his boundless enthusiasm for economics and his steadfast confidence in its capacity for good works economics is very different too both the science and its subject have changed and for the better since world war ii but there are some notable constants unemployment and inflation still preoccupy and perplex economists statesmen journalists housewives and everyone else the connection between them is the principal domestic economic burden of presidents and prime ministers and the major area of controversy and ignorance in macroeconomics i have chosen to review economic thought on this topic on this occasion partly because of its inevitable timeliness partly because of a personal interest reaching back to my first published work in 1941

the long term effects of africa s slave trades can part of africa s current underdevelopment be explained by its slave trades to explore this question i use data from shipping records and historical documents reporting slave ethnicities to construct estimates of the number of slaves exported from each country during africa s slave trades i find a robust negative relationship between the number of slaves exported from a country and current economic performance to better understand if the relationship is causal i examine the historical evidence on selection into the slave trades and use instrumental variables together the evidence suggests that the slave trades have had an adverse effect on economic development

colonialism and modern income islands as natural experiments abstract using a new database of islands throughout the atlantic pacific and indian oceans we find a robust positive relationship between the number of years spent as a european colony and current gdp per capita we argue that the nature of discovery and colonization of islands provides random variation in the length and type of colonial experience we instrument for length of colonization using variation in prevailing wind patterns we argue that wind speed and direction had a significant effect on historical colonial rule but do not have a direct effect on gdp today the data also suggest that years as a colony after 1700 are more beneficial than earlier years we also find a discernable pecking order among the colonial powers with years under u s british french and dutch rule having more beneficial effects than spanish or portuguese rule our finding of a strong connection between modern income and years of colonization is conditional on being colonized at all since each of the islands in our da

colonial legacies and economic growth much of the work on colonialism has been theoretical or anecdotal in this paper i close the gap between the literature on development and new growth theory by testing the effect of colonization on subsequent growth and development in a sample of 63 ex colonial states from 1961 1990 i find that colonies that were held for longer periods of time than other countries tend to perform better on average after independence finally i show that the level of education at the time of independence can help to explain much of the development gap between the former british and french colonies in africa

economic institutions and comparative economic development a post colonial perspective summary existing literature suggests that either colonial settlement conditions or the identity of colonizer were influential in shaping the post colonial institutional environment which in turn has impacted long run economic development these two potential identification strategies have been treated as substitutes we argue that the two factors should instead be treated as complementary and develop an alternative and unified iv approach that simultaneously accounts for both settlement conditions and colonizer identity to estimate the potential causal impact of a broad cluster of economic institutions on log real gdp per capita for a sample of former colonies using population density in 1500 as a proxy for settlement conditions we find that the impact of settlement conditions on institutional development is much stronger among former british colonies than colonies of the other major european colonizers conditioning on several geographic factors and ethno linguistic fractionalization our baseline 2sls estimates suggest that a standard deviation increase in economic institutions is associated with a three fourth standard deviation increase in economic development our results are robust to a number of additional control variables country subsample exclusions and alternative measures of institutions gdp and colonizer classifications we also find evidence that geography exerts both an indirect and direct effect on economic development

on tax efforts and colonial heritage in africa abstract one commonly observed phenomena about taxation in africa are regional differences and the fact that southern african countries have higher levels of shares of taxation in gdp this article argues that the major source of differences in tax effort is the colonial histories of various countries using standard measures of tax effort in a panel data framework and dividing colonial africa along forms of incorporation into the colonial system it shows that african countries and others with similar colonial histories have higher levels of tax effort however the difference disappears when we control for the colonial factor these results hold under different model specifications

a nonparametric investigation of duration dependence in the american business cycle does the termination probability of a business expansion or contraction increase with age this question may be formally addressed by analyzing the nature of duration dependence in aggregate economic activity our null hypothesis is that there is no duration dependence which we test via intentionally nonparametric procedures we also argue that common notion of business cycle periodicity can be usefully interpreted in terms of whole cycle duration dependence we find some evidence for duration dependence in whole cycles and in prewar expansions but little evidence elsewhere

international comparisons of rural urban educational attainment data and determinants we study cross country differences in rural and urban educational attainment by using a data set comprising 56 countries we focus on the determinants of rural urban educational inequality which is measured by the ratio of rural to urban average years of schooling within each country we find that riskier human capital investment less credit availability a colonial heritage a legal system of french origin and landlockedness of nations are all associated with relatively lower rural educational levels and greater rural urban educational inequality conversely larger formal labor markets better infrastructure and a legal system of british origin are associated with relatively higher rural educational levels and lower rural urban educational inequality we also identify an interaction effect between economic development level and some of these factors in particular we find that as development level increases the negative positive relationship between french british legal systems and rural urban educational inequality is reversed and becomes positive negative

nonlinear business cycle dynamics cross country evidence on the persistence of aggregate shocks i introduction economists have long been interested in the dynamics of business cycles particularly regarding the symmetry of expansions and contractions more recently the specification of stochastic trends in economic growth has generated concerns about the relative persistence of positive and negative shocks to the economy several papers have looked at the persistence of business cycles including nelson and plosser 1982 campbell and mankiw 1987 cochrane 1988 diebold and rudebusch 1989 balke and fomby 1990 zelhorst and de haan 1994 and bradley and jansen 1995 while results vary especially on the issue of a unit root in output the overarching result is that output fluctuations are highly persistent one question not asked by the above authors is whether business cycle dynamics are asymmetric this issue has been investigated by neftci 1984 falk 1986 delong and summers 1986 hamilton 1989 diebold and rudebusch 1990 and terasvirta and anderson 1991 these authors take a variety of approaches but they reach a general conclusion that there is some evidence of asymmetric business cycle dynamics however most of these studies ask if contractions are shorter and steeper than expansions except hamilton 1989 they do not ask if there is a difference in persistence due to the asymmetries in a recent paper beaudry and koop 1993 propose a set of methods for simultaneously examining these two questions specifically beaudry and koop bk recommend the augmentation of the standard arma representation of real output growth through the inclusion of a nonlinear term that captures the relative state of the economy this augmentation provides for nonlinear dynamics and the possibility of asymmetric dynamic responses to positive and negative shocks in addition calculation of the implied impulse responses permits detection of the relative persistence implied by the combination of asymmetric cycle dynamics and stochastic trend based upon their analysis of u s data bk conclude that the response of the economy to positive and negative shocks is indeed asymmetric and the imposition of symmetry on impulse responses has likely led to misleading measures of persistence bk p 162 as a result bk conclude we find that the effects of negative shocks to be mainly temporary and the effects of positive shocks to be very persistent bk p 162 if bk s results are correct they have strong implications for the way macro economists view economic fluctuations and will in their words contribute to a reappraisal of some macroeconomic theories that is bk s results suggest that macroeconomic models must be revised to provide for temporary effects of negative shocks but permanent effects of positive shocks because of the potential importance of bk s results we examine the robustness of those results by modifying and extending bk s proposed methods of testing not only do we extend the analysis to the other six g7 countries besides the united states but also we redefine in a sensible way the nature of the nonlinear dynamics overall our results from other economies provide only mixed support for the asymmetry of cyclical dynamics and the lack of persistence of negative shocks ii the model to be estimated in the bk framework the estimated model includes an asymmetric response term the asymmetry is generated by a variable that measures the strength of a recession the variable is calculated as the distance between current real gdp and the previous peak level of real gdp that is bk define a measure they call current depth of the recession cdr where 1 cdr sub t max y sub t j sub j greater than or equal to 0 y sub t with this definition in place bk recommend augmenting an autoregressive model of real gdp growth as 2 phi l delta y sub t delta omega l 1 cdr sub

who was colonized and when a cross country analysis of determinants the process of colonization has shaped the economic and demographic contours of the modern world in this paper we study the determinants of the occurrence and timing of colonization of non european countries by western european powers of particular interest is the role of early development measures that are known to be strong correlates of present day levels of income we show that non european societies with longer histories of agriculture and statehood and higher levels of technology adoption in 1500 were less likely to be colonized and tended to be colonized later if at all we also find that proximity to the colonizing powers disease environment and latitude are significant predictors of the occurrence and timing of colonization although their impacts are less robust to choice of country sample our models have high explanatory power and their support for the significance of early development is robust to the use of alternative indicators of early development and disease to the use of instruments to focus on the exogenous component of early development and to the joint estimation of the colonization and timing equations to correct for potential selection bias

dormancy risk and expected profits of consumer loans abstract a bank that lends money to a household faces two types of risk frequently mentioned is the risk of default seldom referred to is the risk of an early redemption of the loan leading to dormancy in this paper we model the transition of consumer loans from an active to a dormant state to this end we use data on 4786 individuals who were granted credit by a swedish lending institution between september 1993 and august 1995 and estimate a semi parametric duration model we analyze the factors that determine the time to maturity on consumer loans and investigate the ability of the model to match the maturities observed in the data moreover we derive the distribution of conditional expected durations of loans and show how a loan application can be evaluated by calculating its expected profit
