war and natural resource exploitation abstract we build a theoretical framework that allows for endogenous conflict behaviour i e fighting efforts and for endogenous natural resource exploitation i e speed ownership and investments while depletion is spread in a balanced hotelling fashion during peace the presence of conflict creates incentives for rapacious extraction as this lowers the stakes of future contest this voracious extraction depresses total oil revenue especially if world oil demand is relatively elastic and the government s weapon advantage is weak some of these political distortions can be overcome by bribing rebels or by government investment in weapons the shadow of conflict can also make less efficient nationalized oil extraction more attractive than private extraction as insecure property rights create a holdup problem for the private firm and lead to a lower license fee furthermore the government fights less intensely than the rebels under private exploitation which leads to more government turnover without credible commitment to future fighting efforts private oil depletion is only lucrative if the government s non oil office rents are large and weaponry powerful which guarantees the government a stronger grip on office and makes the holdup problem less severe

incentives productivity and labor contracts the relationship between age earnings profiles and worker incentives is examined by contrasting wage and salary workers with the self employed it is argued that the steepness of wage and salary workers age earnings profiles reflects the desire to provide work incentives to those workers since self employed workers do not face this agency problem they are used as a benchmark to gauge productivity empirical support of the proposition is provided and the effects of human capital accumulation are separated empirically from incentive effects the most important conclusion is that under some strong assumptions most of the slope in age earnings profiles is accounted for by the desire to provide incentives rather than by on the job training

rational heuristics expectations and behaviors in evolving economies with heterogeneous interacting agents we analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent based model populated by heterogeneous interacting firms agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change imperfect information coordination hurdles and structural breaks in these circumstances we find that neither individual nor macroeconomic dynamics improve when agents replace myopic expectations with less naive learning rules our results suggest that fast and frugal robust heuristics may not be a second best option but rather rational responses in complex and changing macroeconomic environments jel c63 d8 e32 e6 o4

does lootable wealth breed disorder a political economy of extraction framework this article proposes a political economy of extraction framework that explains political order and state collapse as alternative outcomes in the face of lootable wealth different types of institutions of extraction can be built on lootable resources with divergent effects on political stability if rulers are able to forge institutions of extraction that give them control of revenues generated by lootable resources then these resources can contribute to political order by providing the income with which to govern conversely the breakdown or absence of such institutions increases the risk of civil war by making it easier for rebels to organize the framework is used to explain two puzzling cases that experienced sharply contrasting political trajectories in the face of lootable resources sierra leone and burma a focus on institutions of extraction provides a stronger understanding of the wide range of political outcomes from chaos to dictatorship to democracy in resource rich countries

another century of economic science there is a widespread consensus that during the past century economic science has come of age it has developed powerful statistical tools to analyse economic data to make forecasts and to test alternative hypotheses and it has employed sophisticated mathematical techniques to articulate its theories and to prove basic theorems characterising the economy samuelson 1947 encapsulated the mid century enthusiasm for the scientific method in his classic foundations of economic analysis arguing that economics should be based on observable behaviour and testable hypotheses and with his theory of revealed preference showing how this could be done with the theory of consumers behaviour

financial markets and development my views on this subject have been greatly affected both by the experience of developing countries during the past quarter century and by the major shift evolutionary if not revolutionary in the economists paradigm over that period we have seen that capital accumulation is not enough even the extremely high rates of savings of many of the socialist economies have not managed to compensate for their lack of ability in allocating capital and these countries have for the most part not fared well but extreme free market solutions have fared little better perhaps best illustrated by the experience of chile true believers in the doctrines of the left and the right have this in common they both claim that if the patient had only followed the doctor s orders more precisely the medicine would have worked

cursing the blessings natural resource abundance institutions and economic growth summary since sachs and warner s sachs j d warner a m 1995a natural resource abundance and economic growth nber working paper no 5398 contribution there has been a lively debate on the so called natural resource curse this paper re examines the effects of natural resource abundance on economic growth using new measures of resource endowment and considering the role of institutional quality we find a positive direct empirical relationship between natural resource abundance and economic growth in both ols and 2sls regressions the positive resource effects are particularly strong for subsoil wealth our results also show no evidence of negative indirect effects of natural resources through the institutional channel

geopolitics and international organizations an empirical study on imf facilities there is growing awareness that the distribution of imf facilities may not be influenced only by the economic needs of borrowers this paper focuses on the fact that the imf may favour geopolitically important countries in the distribution of imf loans differentiating between concessional and non concessional facilities to carry out the empirical analysis we construct a new database that compiles a wide array of proxies for geopolitical importance for 107 imf countries over 1990 2003 focusing on emerging and developing economies we use a factor analysis to capture the common underlying characteristic of countries geopolitical importance as well as a potential analysis since we also want to account for the geographical situation of the loan recipients while controlling for economic and political determinants our results show that geopolitical factors influence notably lending decisions when loans are non concessional whereas results are less robust and in opposite direction for concessional loans this study provides empirical support to the view that geopolitical considerations are an important factor in shaping imf lending decisions potentially affecting the institution s effectiveness and credibility

competitive search equilibrium in this paper i construct an equilibrium for markets with frictions which is competitive in the sense that all agents are price takers and maximize utility subject to a set of market parameters i show that the equilibrium allocation is socially optimal i also show how the competitive search equilibrium can be achieved if employers with vacancies can advertise publicly the wages they pay

new perspectives on public finance recent achievements and future challenges abstract the advances in the economics of the public sector during the past quarter century have been as pronounced as in any field within economics public finance has become a rigorous branch of applied microeconomics incorporating the best thinking and most advanced tools of both theoretical economics and econometrics in the remarks below i will focus on a few key areas in applied and theoretical tax and expenditure policy drawing both upon the academic work of myself and others and my experiences in the policy arena both as chairman of the council of economic advisers and as chief economist of the world bank i shall address both the questions of what we have learned in the past few decades as well as the questions where further research is needed

the determinants of social conflict in the latin american mining sector new evidence with quantitative data this paper builds on the case study work into conflict between mining firms and nearby communities through a statistical analysis of the determinants of social conflict at the local level in the mining sector in latin america the analysis is based on an original dataset of 640 geo located mining properties at the advanced exploration stage and above which includes gis information on environment and land use patterns around the property sub national socio economic characteristics of the population firm and mining property characteristics as well as information about known social conflicts

litigation costs and returns to experience we develop a model linking maximum damage awards available to plaintiffs in wrongful termination lawsuits workers propensity to sue as a function of experience and returns to experience using equal employment opportunity commission data on protected worker discrimination complaints and labor market data from the current population survey we examine how returns to experience among protected workers changed around the passage of the civil rights act of 1991 we show that employers reactions to employment protections may induce redistributive effects furthermore these effects operate not merely across groups of differing protected status but also within groups of identical protected status

resource curse or not a question of appropriability this thesis presents three self contained essays focusing on empirical questions in growth and development economics each article addresses specific questions on why countries perform differently in particular i analyse the effect of democracy on economic development the relationship between natural resources and growth and the efficiency of foreign development assistance in the first essay democracy consolidation and growth i analyse the effect of democracy on economic growth in this context i argue that an important aspect to consider is how consolidated political systems are put simply i find that it is not only a question of how democratic countries are but also how long they have been democratic in other words economic performance tends to improve with the duration of uninterrupted democracy the performance of autocracies on the other hand tends to deteriorate over time however for newly established political systems there seems to be a cost of being democratic this implies that democracies only bear their fruit after some time the analysis has important policy implications to overcome initial straits international assistance focused on democratic consolidation may be important and a very good investment in fostering long run development the second essay resource curse or not a question of appropriability together with anne boschini and jesper roine is concerned with the relation between natural resources and economic development for most laymen as well as for most economists it would seem reasonable that countries richly endowed in natural resources also benefit from this wealth however a large literature has found a systematic negative effect of natural resource abundance on economic growth we suggest that this so called resource curse is not determined by resource endowments alone but rather by the interaction between the type of resources a country possesses and the quality of institutions in the country this combination of factors determines what we call the appropriability of a resource the concept of appropriability captures the likelihood of natural resources leading to rentseeking corruption or conflicts which in turn will harm economic development our results suggest that if institutions are good enough the curse may be turned into a blessing this may explain why some countries such as norway and botswana tend to benefit from their resources while others such as angola and sierra leone do not the third and final essay of this thesis foreign sectoral aid fungibility growth and poverty reduction is a contribution to the aid efficiency literature which is concerned with the question of whether aid helps or hinders economic development foreign development assistance is often targeted on specific public expenditure sectors if this aid is not used in the sector for which it was granted e g health education it is said to be fungible and donors may end up financing something completely different from what they intended e g military expenditures the major concern about sectoral fungibility is that the alternative use of aid may be less productive or less socially useful however measuring fungibility is not sufficient to determine whether foreign sectoral aid fungibility is actually harmful what is important is how the funds treated as fungible are used the essay starts by obtaining estimates of fungibility for 57 countries the results suggest that sectoral aid is indeed largely treated as fungible by recipient countries next to assess the economic and health effects of fungibility these estimates are incorporated into an empirical model of aid and growth as well as into a model of aid and infant mortality altogether i find no evidence of more fungible sectoral aid leading to worse performance

rent seeking and resource booms abstract this paper develops a model of rent seeking in which the opportunity cost of rent seeking is foregone entrepreneurship it provides conditions under which resource booms tend to lead to an increase in rent seeking activity and those in which they induce entrepreneurship we identify an important difference between the two activities which leads resource booms to bias gains in favour of rent seeking over entrepreneurship but we also show that this bias depends on the nature of the initial equilibrium

retirement in the uk in common with other oecd countries the uk experienced more than two decades of declining labour market activity among older men from the 1970s to the early 1990s a trend that has only recently shown signs of being reversed retirement decisions are heavily shaped by institutional context and in the uk this has led to there being two distinct groups with very different retirement experiences at the top of the wealth distribution early retirement has typically been influenced by private occupational pensions at the bottom of the wealth distribution individuals are even more likely to be not working in their 50s but do not typically define themselves as retired and draw on income support or more usually disability benefits policy makers keen to increase effective retirement ages will need to consider the very different circumstances of these two groups

the equilibrium effort wage elasticity in efficiency wage models abstract it has been objected that the equilibrium effort wage elasticity of unity in the standard efficiency wage model is quite high and that many of the results in the efficiency wage theory depend critically on the existence of some region of increasing returns of work effort to wages these two objections do not appear in the presence of fixed employment costs which e g implies that the equilibrium effort wage elasticity is less than unity finally some comparative static results are derived

rethinking macroeconomics what failed and how to repair it the standard macroeconomic models have failed by all the most important tests of scientific theory they did not predict that the financial crisis would happen and when it did they understated its effects monetary authorities allowed bubbles to grow and focused on keeping inflation low partly because the standard models suggested that low inflation was necessary and almost sufficient for efficiency and growth after the crisis broke policymakers relying on the models floundered notwithstanding the diversity of macroeconomics the sum of these failures points to the need for a fundamental re examination of the models and a reassertion of the lessons of modern general equilibrium theory that were seemingly forgotten in the years leading up to the crisis this paper first describes the failures of the standard models in broad terms and then develops the economics of deep downturns and shows that such downturns are endogenous further the paper argues that there have been systemic changes to the structure of the economy that made the economy more vulnerable to crisis contrary to what the standard models argued finally the paper contrasts the policy implications of our framework with those of the standard models

do stronger age discrimination laws make social security reforms more effective supply side social security reforms to increase employment and delay benefit claiming among older individuals may be frustrated by age discrimination we test for policy complementarities between supply side social security reforms and demand side efforts to deter age discrimination specifically studying whether stronger state level age discrimination protections enhanced the impact of the increases in the social security full retirement age fra that occurred in the past decade the evidence indicates that for older individuals who were caught by the increase in the fra benefit claiming reductions and employment increases were sharper in states with stronger age discrimination protections

the pandemic economic crisis precautionary behavior and mobility constraints an application of the dynamic disequilibrium model with randomness this article analyzes the economic impact of the pandemic providing insights into the consequences of alternative policies our framework focuses on three key features i covid 19 is a sectoral shock of unknown depth and duration affecting some sectors and technologies more than others ii there are constraints in shifting resources across sectors and iii there is a high level of uncertainty about the disease and its economic aftermath inducing a high level of precautionary behavior by some agents and leading to others facing more severe credit constraints because of macroeconomic externalities precautionary behavior exacerbates the downturn and even sectors where covid 19 does not directly affect consumption or production may face unemployment multipliers associated with different government expenditure programs differ markedly the article describes policies that can mitigate precautionary behavior leading to reduced unemployment greater wage flexibility may lead to increased unemployment the precautionary behavior is the antithesis of equilibrium behavior suggesting that standard equilibrium approaches may not provide the appropriate framework for analyzing the pandemic individuals know that they don t know the future that existing and newly made contracts and plans may be broken and that they need to be able to respond to these unknowable contingencies

the dutch disease a disease after all many third world oil producers are encountering serious problems in building up a diversified export base while west european oil and gas producers netherlands united kingdom are suffering a decline in their traded goods manufacturing sector induced by real wage pressures it is becoming increasingly clear that high but temporary oil revenues may be somewhat ora mixed blessing the quip of the economist notwithstanding the mechanism behind this unbalance is clear enough part of the oil revenues is spent on non traded goods which leads to a real appreciation i e a rise in the relative price of non traded goods in terms of traded goods this in turn draws resources out of the non oil traded sector into the non traded goods producing sector corden and neary 1982 van wijnbergen 1980 one may say that this is an efficient response to the increase in income from oil production the united kingdom mexico egypt simply should move into oil derived industries and non traded goods and forget about their manufacturing sector until oil reserves are exhausted however many developing countries are hesitant to take this advice after all the post world war ii success stories in economic development involve without exception countries that promoted their traded goods sector aggressively moreover it is a well established stylised fact that technological progress is faster in the traded non sheltered sectors of an economy than in the non traded sector balassa 1964 is an early reference considering the hypothesis that technological progress rather than taking place exogenously with the passage of time is a function of accumulated experience the concern of countries like egypt mexico or indonesia is much easier to understand since solow 1957 and denison 1962 it is known that capital accumulation explain only a small part of economic growth if most of economic growth is caused by learning by doing induced technologica

do natural resources fuel authoritarianism a reappraisal of the resource curse a large body of scholarship finds a negative relationship between natural resources and democracy extant cross country regressions however assume random effects and are run on panel datasets with relatively short time dimensions because natural resource reliance is not an exogenous variable this is not an effective strategy for uncovering causal relationships numerous sources of bias may be driving the results the most serious of which is omitted variable bias induced by unobserved country specific and time invariant heterogeneity to address these problems we develop unique historical datasets employ time series centric techniques and operationalize explicitly specified counterfactuals we test to see if there is a long run relationship between resource reliance and regime type within countries over time both on a country by country basis and across several different panels we find that increases in resource reliance are not associated with authoritarianism in fact in many specifications we generate results that suggest a resource blessing

age discrimination laws and labor market efficiency in lazear s model of long term incentive contracts age discrimina tion laws barring age based involuntary terminations preclude such contracts reducing efficiency alternatively such laws may serve as precommitment devices for these contracts without pre venting firms from offering strong financial incentives to induce retirement at specific ages in this case age discrimination laws may encourage lazear contracts hence increasing efficiency we assess evidence on these alternative interpretations using variation in state and federal age discrimination laws the evidence indicates that age discrimination laws steepen age earnings profiles for co horts entering the labor market suggesting that these laws encour age the use of lazear contracts

the contributions of the economics of information to twentieth century economics in the e eld of economics perhaps the most important break with the past one that leaves open huge areas for future work lies in the economics of information it is now recognized that information is imperfect obtaining information can be costly there are important asymmetries of information and the extent of information asymmetries is affected by actions of e rms and individuals this recognition deeply affects the understanding of wisdom inherited from the past such as the fundamental welfare theorem and some of the basic characterization of a market economy and provides explanations of economic and social phenomena that otherwise would be hard to understand i introduction the century coming to a close has seen vast changes in economics in both ideas and methodology upon ree ection it is remarkable however how many of the seeds of advances in this century were sowed in the previous i would argue that perhaps the most important break with the past one that leaves open huge areas for future work lies in the economics of information the recognition that information is imperfect that obtaining information can be costly that there are important asymmetries of information and that the extent of information asymmetries is affected by actions of e rms and individuals has had profound implications for the wisdom inherited from the past and has provided explanations of economic and social phenomena that otherwise would be hard to understand in this essay i wish to argue that information economics has had directly and indirectly a profound effect on how we think about economics today eighteenth and nineteenth century antecedents to be sure marshall and other nineteenth century economists talked about problems of imperfect information but with one exception discussions of information were obiter dicta caveats at the end of the analysis they were never at the center

the voracity effect abstract we analyze an economy that lacks a strong legal political institutional infrastructure and is populated by multiple powerful groups powerful groups dynamically interact via a fiscal process that effectively allows open access to the aggregate capital stock in equilibrium this leads to slow economic growth and a voracity effect by which a shock such as a terms of trade windfall perversely generates a more than proportionate increase in fiscal redistribution and reduces growth we also show that a dilution in the concentration of power leads to faster growth and a less procyclical response to shocks jel f43 o10 o23 o40

effective foreign aid following civil war the nonstrategic desperation hypothesis when does aid foster development after civil war a testable model is needed to account for the uneven outcomes in postconflict development this article proposes and empirically tests the novel nonstrategic desperation hypothesis an explanation based on the varied incentives that fragile postconflict governments face when confronted with donor development goals paradoxically incentives to meet development goals only exist when donors have little strategic interest in the recipients and when recipients lack income from resource rents and are therefore desperate for income ten year data on infant mortality changes following civil wars ending 1970 96 and a variety of robustness checks support the hypothesis by focusing on how income sources constrain the choices of aid recipients and how these constraints can provide incentives to meet donor development goals the nonstrategic desperation hypothesis explains how the good use of aid can take place following civil war when institutions are weak

the quality of political institutions and the curse of natural resources we propose a theoretical model to explain empirical regularities related to the curse of natural resources which emphasises the behaviour and incentives of politicians we extend the standard voting model to give voters political control beyond the elections this gives rise to a new restriction that policies should not give rise to a revolution our model clarifies when resource discoveries might lead to revolutions namely in countries with weak institutions it also suggests that for bad political institutions human capital depends negatively on natural resources while for high institutional quality the dependence is reversed this finding is corroborated in cross section regressions

cursed by resources or institutions natural resource abundant countries constitute both growth losers and growth winners and the main difference between the success cases and the cases of failure lays in the quality of institutions with grabber friendly institutions more natural resources push aggregate income down while with producer friendly institutions more natural resources increase income such a theory finds strong support in data a key question we also discuss is if resources in addition alter the quality of institutions when that is the case countries with bad institutions suffer a double resource curse as the deterioration of institutions strenghtens the negative effect of more natural resources

estimating a firm s age productivity profile using the present value of workers earnings in hiring new workers risk neutral employers equate the present expected value of each worker s compensation to the present expected value of his her productivity data detailing how present expected compensation varies with the age of hire embed therefore information about how productivity varies with age this paper infers age productivity profiles using data on the present expected value of earnings of new hires of a fortune 1000 firm for each of the five occupation sex groups considered productivity falls with age with productivity exceeding earnings for young workers and vice versa for older workers

does foreign aid distort incentives and hurt growth theory and evidence from 75 aid recipient countries foreign aid transfers can distort individual incentives and hence hurt growth by encouraging rent seeking as opposed to productive activities we construct a model of a growing small open economy that distinguishes two effects from foreign transfers i a direct positive effect as higher transfers allow the financing of infrastructure ii an indirect negative effect as higher transfers induce rent seeking competition by self interested individuals in this framework the growth impact of aid is examined jointly with the determination of rent seeking behavior we test the main predictions of the model for a cross section of 75 aid recipient countries there is evidence that aid has a direct positive effect on growth which is however significantly mitigated by the adverse indirect effects of associated rent seeking activities this is especially the case in recipient countries with relatively large public sectors

animal spirits financial crises and persistent unemployment this article uses a rational expectations model with multiple equilibrium unemployment rates to explain financial crises the model has equilibria where asset prices are unbounded above i argue that this is an important feature of any rational agent explanation of a financial crisis since for the expansion phase of the crisis to be rational investors must credibly believe that asset prices could keep increasing forever with positive probability i explain the sudden crash in asset prices that precipitates a financial crisis as a large shock to expectations that leads to a permanent increase in the unemployment rate

financial frictions and employment during the great depression abstract we provide new evidence that a disruption in credit supply played a quantitatively significant role in the unprecedented contraction of employment during the great depression using a novel hand collected dataset of large industrial firms our identification strategy exploits preexisting variation in the need to raise external funds at a time when public bond markets essentially froze local bank failures inhibited firms ability to substitute public debt for private debt which exacerbated financial constraints we estimate a large and negative causal effect of financing frictions on firm employment we find that the lack of access to credit likely accounted for a substantial fraction of the aggregate decline in employment of large firms between 1928 and 1933

savings growth and the resource curse hypothesis an important connection between recent attempts to understand the determinants of economic growth and the measurement of sustainability is the finding of a negative and significant relationship between natural resource abundance and economic growth this is the so called resource curse hypothesis using cross country regressions we offer evidence that the curse may itself be a manifestation of the inability of governments to manage large resource revenues sustainably in particular these results offer another perspective on the resource curse hypothesis the countries where growth has lagged are those where the combination of natural resource macroeconomic and public expenditure policies have led to a low rate of genuine saving net saving adjusted for resource depletion

economic determinants of workers retirement decisions the landscape for older workers has changed dramatically in recent decades governments have made cuts to public pension programs private pensions have shifted from defined benefit to defined contribution plans equity and housing markets have been unusually volatile and workers have experienced declining morbidity and mortality at the same time the labor force participation rate for older men and women has been rising over the past two decades implying later retirement are these phenomena related this paper reviews the large and growing body of literature exploring the economic determinants of workers retirement decisions including public and private pensions wealth and savings health and health insurance and labor demand

why was there mandatory retirement abstract lazear argues that hours constraints and mandatory retirement form part of an efficient contract which inhibits worker shirking he argues that initially workers earn less than their vmp and must work more than they want while later they earn more than their vmp and must work less however if bonding is costly incentive compatibility requires that workers can never exceed the contracted hours in addition hours will be set so that vmp exceeds the disutility of employment consequently being paid more than their vmp is only sufficient not necessary for workers to be constrained to work less than they wish

the narrow moving band the dutch disease and the competitive consequences of mrs thatcher notes on trade in the presence of dynamic scale economies abstract this paper presents a model of trade in which comparative advantage instead of being determined by underlying attributes of countries evolves over time through learning by doing in this model arbitrary patterns of specialization once established tend to become entrenched over time the model sheds light on three widely held views that do not make sense in more conventional models first is the view that temporary protection of selected sectors can permanently alter the pattern of comparative advantage in the protecting country s favor second is the view that seemingly favorable developments such as the discovery of exportable natural resources may lead to a permanent loss of other sectors and reduce welfare in the long run third is the possibility that a temporary overvaluation of a currency due to tight money can lead to a permanent loss of competitiveness in some sectors

gold exploitation and socioeconomic outcomes the case of burkina faso abstract in the early 2000s burkina faso launched several legal reforms aimed at increasing gold production this resulted in a gold mining boom making gold the main export product and the main source of economic growth of the country we hypothesize that gold extraction improved population living standards this paper investigates how the gold boom in burkina faso which began in 2007 has affected socioeconomic outcomes we use a simple theoretical model to motivate the testing of several hypotheses regarding these impacts employing a difference in differences strategy as well as panel data models we estimate the impacts using data from household surveys undertaken in 2003 and 2009 and administrative data consistent with our model the results suggest that areas hosting gold extraction have better average living standards in terms of headcount ratios poverty gaps and household expenditures than do areas without gold however the gold boom is also shown to have potentially increased local inequality and child labor in areas with these income gains these results demonstrate the importance of proactive government policy in mitigating negative welfare impacts

institutions and the resource curse countries rich in natural resources constitute both growth losers and growth winners we claim that the main reason for these diverging experiences is differences in the quality of institutions more natural resources push aggregate income down when institutions are grabber friendly while more resources raise income when institutions are producer friendly we test this theory building on sachs and warner s influential works on the resource curse our main hypothesis that institutions are decisive for the resource curse is confirmed our results contrast the claims of sachs and warner that institutions do not play a role

history lessons institutions factor endowments and paths of development in the new world the explanations offered for the contrasting records of long run growth and development among the societies of north and south america most often focus on institutions the traditional explanations for the sources of these differences in institutions typically highlight the significance of national heritage or religion we in contrast argue that a hemispheric perspective across the wide range of colonies established in the new world by the europeans suggests that although there were many influences factor endowments or initial conditions had profound and enduring effects on the long run paths of institutional and economic development followed by the respective economies

natural resources rent seeking and welfare abstract a new and very simple mechanism to explain why natural resource abundance may lower income and welfare is developed in a model with rent seeking a greater amount of natural resources increases the number of entrepreneurs engaged in rent seeking and reduces the number of entrepreneurs running productive firms with a demand externality it is shown that the drop in income as a result of this is higher than the increase in income from the natural resource more natural resources thus lead to lower welfare

externalities in economies with imperfect information and incomplete markets this paper presents a simple general framework for analyzing externalities in economies with incomplete markets and imperfect infonnation by identifying the pecuniary effects of these externalities that net out the paper simplifies the problem of determining when tax interventions are pareto improving the approach indicates that such tax interventions almost always exist and that equilibria in situations of imperfect information are rarely constrained pareto optima it can also lead to simple tests based on readily observable indicators of the efficacy of particular tax policies in situations involving adverse selection signaling moral hazard incomplete contingent claims markets and queue rationing equilibria traditional discussions of externalities have emphasized the distinction between technological externalities in which the action of one individual or firm directly affects the utility or profit ofanother and pecuniary externalities in which one individual s or firm s actions affect another only through effects on prices while the presence of technological externalities imply in general that a competitive equilibrium may not be pareto efficient pecuniary externalities hy themselves are not a source of inefficiency the fact that prices change has of course important consequences there are both distributional and allocational effects but the distribution effects net out gains for example hy firms whose prices increase are precisely offset by losses e g to individuals who must pay higher prices and there are no welfare losses from the allocation effects as long as the price changes involved are small if firms are maximizing profits and individuals are maximizing utility both facing prices that correctly refiect opportunity costs then standard envelope theorem arguments imply that changes in profits or utility induced by changes in allocations resulting from any small change in prices are negligible

oil and regime type in latin america reversing the line of causality abstract in its first generation the literature on the resource curse typically posited that resource dependence shapes a country s economy and politics more recent work posits that the effects are mediated by institutions we take this newer approach further by arguing that economic and political institutions not just mediate but actually shape resource dependence our focus is on performance across national oil companies nocs in latin america we explain performance variation by invoking variations in regime and market features nocs that operate in contexts of greater independence from the executive branch stronger checks and balances within and outside the sector and greater market forces though not necessarily private actor dominance exhibit better performance institutions thus influence sector conditions rather than the other way around we advance this argument using original data from colombia and venezuela and supplementary data from mexico brazil and argentina our study focuses on the oil boom bust cycle of 2003 2016

the money doctor in the andes the kemmerer missions 1923 1933 the money doctor in the andes is an account of the technical assistance missions to five andean republics colombia ecuador chile bolivia and peru undertaken by princeton university economist edwin walter kemmerer during the 1920s drake demonstrates that in each case the kemmerer mission recommended an identical series of monetary fiscal and banking reforms adding occasional recommendations on everything from administrative reorganization to penal code reform as local circumstances seemed to warrant in each case too local legislatures adopted all the main kemmerer proposals virtually without debate or modifications drake links the kemmerer missions to vital developments in the political economic history of the andean republics in the interwar period he analyzes the domestic interest groups and political forces whose convergent strategies gave the kemmerer missions their remarkable record in achieving local success for the reforms proposed second drake situates the kemmerer missions at the center of a process of political modernization that created new institutions and policy agencies in each of the five countries the missions thereby contributed to the expansion of the central government as an agent of development in ways that later differed sharply from kemmerer s orthodox policies finally the money doctor in the andes regards developments in the andean countries in the context of the region s developing economic ties to the united states expectations that kemmerer s plans would simultaneously attract foreign capital and control inflation drew support from sectors as diverse as trade unions and landowners when the depression deepened kemmerer s policies proved counterproductive and the fragile consensus that had installed them fell apart but the political and administrative reforms endured with far reaching consequences

increasing returns and the genesis of american resource abundance the usa became the world s leading mineral producing nation between 1870 and 1910 a development paralleled by the rising resource intensity of american manufacturing this paper challenges the premise that resource abundance simply reflected the country s geological endowment of mineral deposits instead in the century following 1850 the usa exploited its natural resource potentials to a far greater extent than other countries and did so across virtually the entire range of industrial minerals the paper argues that natural resource abundance was an endogenous socially constructed condition that was not geologically preordained it examines the complex legal institutional technological and organizational adaptations that shaped the us supply responses to the expanding domestic and international industrial demands for minerals and mineral products it suggests that strong positive feedbacks even in the exploitation of depletable resources were responsible for the explosive growth of the american minerals economy

imf bailouts and moral hazard this paper empirically investigates the extent of investor moral hazard associated with imf bailouts by analyzing the responses of sovereign bond spreads to the changes in the perceived probability of imf bailouts of countries undergoing financial crisis we do not find strong evidence that the extent of investor moral hazard changed after the non bailout of russia in august 1998 that signaled a modification to imf intervention policy in contrast we find evidence that investor moral hazard is intensified for those countries that have stronger political connections to the imf and that are thereby more likely to be bailed out by the imf this pattern prevailed even after the russian crisis

the effects of a natural gas boom on employment and income in colorado texas and wyoming improvements in technology have made it profitable to tap unconventional gas reservoirs in relatively impermeable shale and sandstone deposits which are spread throughout the u s mostly in rural areas proponents of gas drilling point to the activity s local economic benefits yet no empirical studies have systematically documented the magnitude or distribution of economic gains i estimate these gains for counties in colorado texas and wyoming three states where natural gas production expanded substantially since the late 1990s i find that a large increase in the value of gas production caused modest increases in employment wage and salary income and median household income the results suggest that each million dollars in gas production created 2 35 jobs in the county of production which led to an annualized increase in employment that was 1 5 of the pre boom level for the average gas boom county comparisons show that ex ante estimates of the number of jobs created by developing the fayetteville and marcellus shale gas formations may have been too large

introduction epistemic communities and international policy coordination the growing technical uncertainties and complexities of problems of global concern have made international policy coordination not only increasingly necessary but also increasingly difficult if decision makers are unfamiliar with the technical aspects of a specific problem how do they define state interests and develop viable solutions what factors shape their behavior under conditions of uncertainty what are the origins of international institutions and how can we best study the processes through which international policy coordination and order emerge while a variety of analytic approaches have been used to address the problems of international cooperation the approaches have yielded only fragmentary insights at its core the study of policy coordination among states involves arguments about determinism versus free will and about the ways in which the international system is maintained and transformed among the overlapping topics of debate are whether national behavior is determined or broadly conditioned by system level factors unit level factors or some complex interplay between the two whether state policymakers can identify national interests and behave independently of pressures from the social groups they nominally represent and whether states respond consistently to opportunities to create defend or expand their own wealth and power to enhance collective material benefits or to promote nonmaterial values a related question of

cartels in an nth best world the wholesale foodstuff trade in ibadan nigeria abstract the purpose of this paper is to develop an understanding of the economic functions and associated welfare implications of the cooperative associations that dominate the wholesale trade in two staple foods questionnaire responses lead to several conclusions individual traders face incomplete markets imperfect information and little government provided institutional and physical infrastructure the associations are sophisticated coase like responses to this market environment they focus on reducing their members transaction costs and hence the marginal private costs of trading thus it is likely that these associations enhance efficiency we conclude with a critique of current government policy with respect to this trade

economic determinants of the optimal retirement age an empirical investigation in this paper we examine how the structures of earnings social security and pension benefits affect retirement behavior we use an intertemporal model of labor supply paying special attention to the institutional features of private pensions and social security benefits this theoretical formulation produces comparative dynamic predictions and guides empirical modeling data from a new survey of workers and their income opportunities are used to implement the empirical model on the basis of empirical retirement estimates we conclude that 1 people with higher base wealth retire earlier and 2 those who expect to gain more by postponing retirement retire later

oil and women a re examination abstract in a seminal article ross 2008 reports a negative correlation between oil production and women s representation in the labour force and politics across countries this article re examines these relationships exploiting variations in oil endowments to address endogeneity concerns we confirm that oil production causes decline in women s representation additionally we show that consistent with dutch disease effects oil production decreases women s employment in the traded sector however it also leads to an increase in women s employment in the nontraded sector we explore some social consequences of oil production and show that it results in women marrying earlier and having more children

is mandatory retirement overrated evidence from the 1970s in this paper we argue that mandatory retirement is only one aspect of a much broader system that influences an individual s retirement decision we look at responses over time to variations in mandatory retirement rules faced by a sample of private sector workers aged 62 64 in 1973 this is done within a model that specifically includes the economic incentives present in social security and pension systems we find that the impact of a mandatory retirement rule on work is considerably smaller than a simple comparison of those with and without mandatory retirement would imply

learning by doing and the dutch disease this paper develops a model of learning by doing and the dutch disease that extends the earlier literature in two ways first it is assumed that both the traded and the non traded sector can contribute to learning second it is assumed that there are learning spillovers between the sectors it is shown that within such a model a foreign exchange gift results in a real exchange rate depreciation in the long run due to a shift in the steady state relative productivity between the traded and the non traded sector in contrast to standard models of the dutch disease production and productivity in both sectors may go up or down the conditions for the different cases are worked out

social divisions and institutions assessing institutional parameter variation this paper investigates the hypothesis that the association between property rights institutions and income is weaker in countries with high social divisions it argues that social divisions should have a negative effect on perceived institutional inclusiveness which in turn should depress institutional payoffs absent a property rights indicator that captures the perceived inclusiveness of institutions social divisions should then weaken the observed association between property rights institutions and income the empirical results support this hypothesis and highlight the importance of evaluating whether the institutions measure used captures the institutional framework applying to the population at large

confidence crashes and animal spirits this article is an attempt to reformulate what i take to be two key insights from keyness general theory keynes 1936 the first is that there is something profoundly different about the labour market from most other markets in the economy the second is that the beliefs of participants in the asset markets have an independent influence on economic activity in the language of modern dynamic general equilibrium theory we would say that there is a continuum of labour market equilibria and that beliefs about the value of the stock market select an equilibrium the general theory contains many ideas some of which are internally inconsistent and keynes did not try to reconcile his theory with walrasian economics that task was carried out by a group of interpreters including hansen 1936 and hicks 1937 the current dominant paradigm new keynesian economics originated with the third edition of samuelson s 1955 undergraduate textbook in which he introduced the idea of the neoclassical synthesis according to this doctrine the economy is keynesian in the short run but classical in the long run the short run is defined as the period over which not all prices have had time to adjust to their walrasian levels this article introduces a different interpretation of the key ideas from the general theory 1 although my work is inspired by keynesian economics this article is not about the history of thought i offer a way of formulating the idea that market economies are not inherently self stabilising without assuming that prices or wages are prevented from adjusting to their equilibrium levels by some kind of friction instead i claim that high persistent unemployment is a potentially permanent feature of a market economy in a steady state equilibrium

insecure resources bilateral trade and endogenous predation a game theoretic analysis of conflict and trade this article analyzes how interstate conflict over resources affects the incentives to trade and how greater trade openness affects the endogenous decisions of arming by enemy countries we identify conditions under which there is trade between two adversary countries and show that each adversary s arming affects domestic welfare in three different ways the first is an export revenue effect which increases welfare because arming causes export revenue to go up i e there is an arming induced terms of trade improvement the second is a resource predation effect which increases welfare because arming increases the appropriation of a rival country s resource input to produce a consumption good the third is an output distortion effect which reduces welfare because arming lowers the domestic production of civilian goods based on these effects we show circumstances in which greater trade openness reduces the intensity of arming we also discuss the implications of resource security asymmetry for conflict and trade

shining a light on the resource curse an empirical analysis of the relationship between natural resources transparency and economic growth summary one of the most common policy prescriptions for overcoming the so called resource curse particularly for extractive industries has been to call for greater transparency and accountability from governments however despite the conceptual attraction of this policy it has never been empirically proven that resource rich countries are actually less transparent than other countries and whether this lack of transparency has had a significant negative effect on economic growth using a relatively new index of transparency that has extensive coverage both across countries and time the results suggest a strong and robust negative causal association running from point resource export revenues to transparency furthermore there is also some evidence that this lack of transparency is associated with a subsequent decrease in economic growth

cointegrating institutions the time series properties of country institutional measures abstracta country s political and economic institutions are critical for economic prosperity the literature abounds with institutional measures precisely because institutions are multidimensional we use panel unit root and cointegration tests to examine the time series properties of several institutional measures to answer two questions first do institutional changes tend to be permanent second which subsets of institutions tend to converge or move together these answers have important implications for whether permanent institutional reform is possible and whether reforms can be undertaken one institutional area at a time or instead must simultaneously encompass multiple institutional areas

kleptocracy and divide and rule a model of personal rule many developing countries have suffered under the personal rule of kleptocrats who implement highly inefe cient economic policies expropriate the wealth of their citizens and use the proceeds for their own glorie cation or consumption we argue that the success of kleptocrats rests in part on their ability to use a divide and rule strategy made possible by the weakness of institutions in these societies members of society need to cooperate in order to depose a kleptocrat yet such cooperation may be defused by imposing punitive rates of taxation on any citizen who proposes such a move and redistributing the benee ts to those who need to agree to it thus the collective action problem can be intensie ed by threats which remain off the equilibrium path in equilibrium all are exploited and no one challenges the kleptocrat kleptocratic policies are more likely when foreign aid and rents from natural resources provide rulers with substantial resources to buy off opponents when opposition groups are shortsighted when the average productivity in the economy is low and when there is greater inequality between producer groups because more productive groups are more dife cult to buy off jel o12 h00

minerals institutions openness and growth an empirical analysis competing explanations of the resource curse are tested using panel data the data support the existence of a mineral resource curse for developing countries with weak institutions consistent with the hypothesis that owners of mineral resources use weak institutions and openness to trade to stifle the development of human capital to the detriment of growth in other sectors of the economy manufacturing imports substitute for the development of domestic production so openness to trade correlates with lower growth in mineral dependent economies the dutch disease and debt overhang explanations of the resource curse are not supported

studying the role of political competition in the evolution of government size over long horizons here we argue for the use of cointegration and error correction analysis to combine economic factors that are nonstationary with political factors that are stationary into an empirical model of the evolution of public policy over long periods the approach is applied to disentangle the contributions of economics and politics to the evolution of public expenditure by the government of canada over 130 years political competition emerges as the primary political factor affecting government size

how do mineral states learn path dependence networks and policy change in the development of economic institutions summary based on case study methods i draw lessons from the political economy of macroeconomic management in chile and peru to explain how mineral states learn to think long term and eventually escape the resource curse i give an institutionalist account of the rise of countercyclical funds showing how the long term development of elite networks qualifies the contemporary making of curse escapes policy networks compose one central avenue of institutional development for both the reproduction of path dependence and the making of institutional change the exposition challenges political economy of development frameworks which over emphasize structural initial conditions and assume steady rent seeking behavior of state agents

economic backwardness in political perspective government policies and institutions shape economic incentives and via this channel have a first order impact on economic development why then do many societies adopt policies that discourage investment and maintain institutions that cause economic backwardness perhaps politically powerful groups elites are not in favor of economic growth but why it would appear that economic growth would provide more resources for these groups to take over or tax increasing their economic returns so why don t powerful groups always support economic development in this paper we develop a theory of inefficient government policies and institutions all else equal politically powerful groups would welcome superior institutions and technologies but in practice all else is not equal because superior institutions and technologies may reduce their political power and make it more likely that they will be replaced at the center of our theory is therefore the idea that changes in institutions or the introduction of new technologies often create turbulence eroding the political advantages and future economic rents of incumbent elites alternatively new technologies may enrich competing groups increasing their threat to incumbents these considerations make politically powerful groups fear losing power and oppose economic and political change even when such change will benefit society as a whole to understand the mechanism at work and its potential applications consider a concrete example industrialization in the nineteenth century bairoch 1982 estimates that between 1830 and 1913 world manufacturing output increased by a factor of 5 see table 1 panel a nevertheless this process was highly uneven across regions and countries bairoch also calculates that over the same period manufacturing output in developed countries europe and north america increasedbyafactorofover10 whereasitdeclinedinthe third world among developed countries there were

political foundations of the resource curse in this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse we show 1 politicians tend to over extract natural resources relative to the efficient extraction path because they discount the future too much and 2 resource booms improve the efficiency of the extraction path however 3 resource booms by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections increase resource misallocation in the rest of the economy 4 the overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create countries without such institutions however may suffer from a resource curse

a structural retirement model the life cycle model analyzed here constrains most work on the main job to be full time partial retirement entails a wage reduction and frequently a job change maximum likelihood estimates of utility function parameters are designed to incorporate information on the age of leaving full time work and the age of full retirement the model closely tracks retirement behavior including peaks in retirement activity at 62 and 65 the paper explores the relation of these peaks to nonlinearities in the budget constraint created by various retirement programs policy analyses based on this and on earlier models with simpler structures are compared the retirement choice is one of the more prominent manifestations of life cycle behavior the decision is the result of an interplay between an individual s preferences and a set of incentives which change in complicated ways as the individual progresses through his or her late 50 s and 60 s the purpose of this study is to formulate and estimate a structural model which incorporates in a fundamental way this interplay between lifetime preferences and incentives and to illustrate how such a model may be used to investigate retirement behavior a structural model of this type is essential for analyzing potential policy changes which can be expected to affect incentives in varying ways over a number of years in the life cycle the current study incorporates two structural features which have frequently been omitted from previous studies first the model requires that an individual who wishes to reduce work effort below full time must accept a reduced hourly wage rate in order to do so this reflects empirical evidence from micro data sets which indicates that around one third of older individuals engage in part time work at one time or another and that regardless of whether or not these older workers change jobs to obtain part time work they usually take wage cuts as compared to their previous full time work 2 the fact that an individual is willing to accept a lower wage rate in return for the opportunity to work fewer than full time hours contains important information about the preferences of the

corruption and the political economy of resource based development a comparison of asia and sub saharan africa we model how the supply and demand for bribes affects resource use by an economy and the reinvestment of resource rents in other assets this requires adjusting the world bank s measure adjusted net savings for any rent dissipation due to corruption the impacts of corruption on long run changes and periodic growth in the adjusted net savings rate are estimated across african and asian economies from 1970 to 2003 corruption rather than resource dependency per se affects negatively the ability of african countries to reinvest resource rents in the short term but for asian countries corruption is less important than point resources corruption influences long run growth in adjusted net savings rates in all countries and is also the pathway through which this growth is affected by patterns of resource use trade and abundance

population ageing and labour markets in the face of rapid population ageing the long run fall in effective retirement ages in most oecd countries needs to be reversed there are some positive signs that this is beginning to happen but early exit from the labour force i e well before official old age pension ages still remains a very common phenomenon in oecd countries in this paper we first compare recent trends in the labour situation of older workers across oecd countries this is followed by a discussion of supply side and demand side factors that have been driving these trends in particular new evidence is presented on incentives to retire that are embedded in pension systems we conclude that recent reforms in most countries in this area are working in the direction of encouraging later retirement although in a few countries there are still substantial incentives to stop working early we then examine to what extent there are barriers on the demand side which may also be discouraging work at an older age such as age discrimination seniority rules in wage setting low training participation and employment protection rules we conclude that countries have also begun to tackle these barriers as well nevertheless while considerable pension reform has undoubtedly strengthened incentives to continue working at an older age further action is still required on the demand side to ensure that those older workers who wish to work longer can do so copyright 2010 oxford university press

trade matters in the fight against poverty narratives perceptions and lack of evidence in the case of fish trade in africa two opposing views exist in the literature on the potential role that international fish trade plays in economic development while some claim that fish trade has a pro poor effect others denounce the negative effect of fish export on local populations food security and doubt its contributions to the macro economy in this paper we explore this debate in sub saharan africa our analysis did not find any evidence of direct negative impact of fish trade on food security neither did it find evidence that international fish trade generates positive pro poor outcomes this paper discusses the possible reasons for this apparent lack of development impact and highlights the unsupported assumptions underlying the current discourse about international fish trade we suggest that given lack of evidence for the development benefits of fish trade between africa and developed countries fisheries policy could consider support for regional africa to africa trade that meets the growing african demand for lower value fish means of overcoming barriers to intra african trade in fish are discussed

natural resources and the tradeoff between authoritarianism and development abstract why do african and middle eastern countries seem cursed by an abundance of natural resources yet usa australia and norway seem blessed a growing literature has argued that the benevolence or malignance of natural resources depends upon the quality of institutions this paper offers a new explanation based on associational freedom and its interaction with the political system the model predicts that natural resources have an adverse impact on economic performance and transition to democracy in authoritarian regimes but not in democracies it also predicts that repression of associational freedom will be increasing in natural resources in authoritarian regimes i test the model s predictions using fixed effects regressions on an international panel from 1975 to 2000 and find support
