the state and economic stagnation in tropical africa abstract politics while only one strand in the explanation of africa s massive economic problems is nonetheless a significant factor a central conundrum facing postcolonial political leaders is how to govern and hold together unintegrated peasant societies in the absence of legitimacy personal rule a particular mode of patrimonial governance provides an answer permitting regime survival and the advancement of political insiders but personal rule has an economically destructive tendency that only shrewd political leadership and propitious world economic conditions can check if uncontrolled certain political practices corrode bureaucratic and legal rationality and promote the misallocation of scarce public resources the result can be a downward spiral of interrelated political and economic decline that is increasingly difficult to reverse

public capital and long run costs in u k manufacturing a model of u k manufacturing production that incorporates the inputs of public as well as private capital is specified and estimated the model is then used to measure the contribution of public capital to productivity growth over the period 1966 to 1990 it is found that before 1980 the public and private capital contributions were of comparable magnitude after 1980 the contribution of public capital declined significantly copyright 1993 by royal economic society

the political economy of financial reform are abiad and mody right motivated by the questions financial reform what shakes it what shapes it raised by abiad and mody 2005 this paper studies the forces that induce governments to undertake financial sector reform rather than their ordered logit technique it uses a within groups approach allowing for error dependence across countries and over time this analysis shows that some of the am findings are not robust to error dependence and the estimation method it has shed new light on the political economy of financial reform copyright 2009 john wiley sons ltd

who provides the capital for chinese growth the public or the private sector we focus on the role of the government in the provision of investment in china through the medium of a dynamic stochastic general equilibrium model of the economy in which the form of the production function reflects this governmental role using indirect inference we estimate and test for the elasticity of substitution between government and nongovernment capital in both constant elasticity of substitution ces and cobb douglas technologies the results underscore the strong substitution relationship between government and nongovernment capital from 1949 supporting ces rather than the cobb douglas technology they also show that the orientation of public investment changed after the start of the socialist market economy in 1992 government capital became more complementary to nongovernment capital as it focused more on infrastructure and withdrew from industrial production intervening only in times of crisis for stabilization purposes indirectly via the state banks

the economics of forced migration abstract this article reviews the economics literature on the impacts of forced migration the literature is divided into two parts impacts on forced migrants and impacts on host communities studies exploring the impact of forced migration due to wwii suggest that the long term impact is often positive the literature for developing countries suggests that there are serious consequences of forced migration for those forced to migrate these consequences range from worse labour market outcomes to less consumption smoothing the impact on host communities seems to be mixed and there are winners and losers the article provides suggestions for future research

immigration and prices this paper examines the behavior of prices following the unexpected arrival of a large number of immigrants from the former soviet union fsu to israel during 1990 i use store level price data on 915 consumer price index products to show that the increase in aggregate demand prompted by the arrival of the fsu immigration significantly reduced prices during 1990 when one controls for native population size and city and month effects a one percentage point increase in the ratio of immigrants to natives in a city decreases prices by 0 5 percentage point on average it is argued that this negative immigration effect is consistent with fsu immigrants the new consumers having higher price elasticities and lower search costs than the native population thus immigration can have a moderating effect on inflation through its direct effect on product markets and not only by increasing the supply of labor

the dual nature of public goods and congestion the role of fiscal policy revisited the role of fiscal policy is examined when public goods provide both productive and utility services in the presence of congestion the consumption tax is shown to be distortionary optimal fiscal policy involves using consumption based instruments in conjunction with the income tax an income tax financed increase in government spending dominates both lump sum and consumption tax financing replacing the lump sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax these results contrast sharply with the literature where the consumption tax is generally viewed as the least distortionary source of public finance on re examine le role de la politique fiscale quand les biens publics fournissent a la fois des services productifs et de bien etre quand il y a congestion on montre que la taxe sur la consommation cree des distorsions la politique fiscale optimale consiste a faire bon usage des taxes sur la consommation en conjonction avec l impot sur le revenu une depense gouvernementale financee par l impot sur le revenu est preferable a un financement par un paiement forfaitaire ou une taxe sur la consommation remplacer le paiement forfaitaire par un impot sur le revenu pour financer un niveau donne de depense vaut mieux qu introduire une taxe equivalente sur la consommation ces resultats contrastent vivement avec ce qu on trouve dans la litterature specialisee ou l on considere generalement la taxe sur la consommation comme la source de finance publique qui cree le moins de distorsion

is the relationship between financial development and economic growth monotonic evidence from a sample of middle income countries summary we revisit the relationship between financial development and economic growth in a panel of 52 middle income countries over the 1980 2008 period using pooled mean group estimations in a dynamic heterogeneous panel setting we show that there is an inverted u shaped relationship between finance and growth in the long run in the short run the relationship is insignificant this suggests that too much finance can exert a negative influence on growth in middle income countries the finding of a non monotonic effect of financial development on growth is confirmed by estimating a threshold model

congestion function specification and the publicness of local public goods abstract this paper is about the measurement of congestion within the median voter demand framework the model of congestion traditionally used in the literature and four others are compared and tested in a median voter framework the results show that a more flexible functional form which imposes fewer a priori restrictions on the data does at least as good a job of explaining variations in local government expenditures furthermore it is shown that measured publicness of local public goods depends entirely on the a priori restrictions imposed on the congestion function

crisis in the eye of the beholder economic crisis and partisan politics in latin american and east european international monetary fund programs this article analyzes the interaction between economic crises and partisan politics during international monetary fund program initiation in latin america in the 1980s and eastern europe in the 1990s the author argues that economic crises are at least in part in the eye of the beholder and therefore policy responses reflect the interaction between crisis intensity and the government s partisan interpretation of the crisis which in turn depends on the nature of the economic crisis and its broader regional and international environment using cross country statistical evidence from the two regions the article shows that certain types of crises such as liquidity shortfalls elicit similar responses across the ideological spectrum and regional contexts by contrast debt repayment and domestic crises are more prone to divergent ideological interpretations but the extent of partisan divergence is context sensitive in that it occurred during the latin american debt crisis but not in the post communist tra

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

indeterminacy under constant returns to scale in multisector economies recently there has been a renewed interest in indeterminacy or alternatively put in the existence of a continuum of equilibria in dynamic economies that exhibit some market imperfections one of the primary concerns of this literature has been the empirical plausibility of indeterminacy which arises in markets with external effects or with monopolistic competition often coupled with some degree 10 of increasing returns

infrastructure investment a review essay economists try not to be faddists but they often cannot help themselves while work on a topic should mirror the prospective importance of the topic that situation seems to occur with disappointing frequency instead the usual pattern is that some reasonably important topic will be totally ignored for the longest time then recognized and then the subject of a flurry of work all out of proportion to its likely long run importance nowhere has this speculative bubble of economic research been more clearly illustrated than with infrastructure investment macroeconomists havelong felt that the stock of public capital is an important factor input in the production of total output macroeconomists have known that u s productivity growth slowed dramatically in about 1973 and macroeconomists should have known that united states investment in public capital has been down since the late 1960s yet analysis of the u s productivity slowdown completely ignored infrastructure investment for the first fifteen years of this slowdown concentrating instead on energy prices social regulation the composition of the work force research and development different rates of obsolescence of the private capital stock and any number of other matters the public capital stock was hardly ever even mentioned as a potential factor in the productivity slowdown aschauer changed all that he wrote a series of papers 1989a 1989b 1989c that put these two movements together econometrically infrastructure investment turned down and aggregate productivity turned down slightly later both in the united states and in some other developed countries his work hit the magic button those who had worried about the productivity puzzle for fifteen years welcomed a new suspect those who were worried about low rates of u s national saving welcomed a new way to make their argument even more forcefully than with official figures on saving and investment which do not count infrastructure investment as investment political liberals and liberal politicians saw a way to rescue government spending and projects from the assaults of reaganism and even a way to avoid oth

what drives the swing voter in africa what makes african voters up for grabs existing approaches to the swing voter have several liabilities this article introduces a new measure enabling a more comprehensive assessment of swing voting including the differentiation between clientelistic and collective goods motivations the issue of swing voting is then brought to an environment where voters are rarely considered persuadable africa using a count model estimation technique and original survey data from ghana s critical 2008 elections the analysis challenges the near consensus in african politics on clientelism as the only electoral strategy when voters perceive politicians as providing collective developmental goods the efficacy of clientelism as a tool to win over voters is reduced many persuadable voters can also be won over by both clientelistic and collective goods thus contradicting the literature presenting these as mutually exclusive finally the analysis shows that incumbents do better when they provide collective goods even in highly clientelistic environments

scale congestion and growth this paper explores the relationship between aggregate and relative congestion returns to scale and economic growth aggregate congestion reduces the effective productivity of capital relative congestion reduces the effective productivity of labour both forms of congestion adversely affect the equilibrium growth rate although their relative effects depend upon aggre gate returns to scale the two forms of congestion have contrasting effects on the transitional dynamics relative congestion retards the rate of adjustment aggregate congestion accelerates it the externalities generated by congestion and non optimal expenditure can be fully cor rected both during the transition and in steady state by a time invariant income tax the role of public expenditure as an instrument of economic growth has been a major policy issue as governments throughout the world design stimulus packages as in japan and face difficult choices to meet the emu criteria in europe empirical research investigating the impact of public investment on the productivity of private capital and output was stimulated by aschauer 1989a b who found the effects to be strongly positive the nature of public investment is however diverse in general public goods vary extensively in terms of the nature of their services spanning the range between the polar cases of pure private and pure public goods but the treatment of public expenditures in formal growth models is limited barro 1990 and futagami et al 1993 treat government expenditure as a pure pub lic good and in so doing they fail to take account of the congestion typically associated with public goods however as barro and sala i martin 1992 have argued almost all public services are characterized by some degree of congestion so that the pure public good should be viewed as only a bench mark these considerations suggest that congestion is an important consider ation in assessing the effect of public expenditures on economic growth attempts to analyse the effects of congestion on economic growth have been limited in various dimensions drawing on the public goods literature edwards 1990 proposes a number of specifications of congestion two notions particularly relevant in a growth context are relative congestion and aggregate absolute congestion the former specifies the level of services derived by an individual from the provision of a public good in terms of the usage of his individual capital stock relative to the aggregate capital stock aggregate congestion sometimes called crowding indicates how aggregate usage of the service alone influences the services received by an individual 2 existing applications of congestion to growth theory introduce it into ak models see barro and sala i martin 1992 1995 glomm and ravikumar 1994 1997 and turnovsky 1996 1997 however the ak model features two limitations that restrict its flexibility to examine the relationship between congestion and growth first as solow 1994 pointed out sustained ongoing

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

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

fiscal policy elastic labor supply and endogenous growth abstract endogenizing labor supply leads to fundamental changes in the equilibrium structure of the ak growth model the balanced growth equilibrium can be described in terms of two tradeoff loci relating the equilibrium growth rate to the fraction of time devoted to leisure the implications of endogenous labor supply for fiscal policy are analyzed three issues are addressed first the effects of various distortionary tax changes and government expenditure changes on the equilibrium growth leisure employment tradeoff are analyzed second optimal fiscal policy is characterized finally the formal analysis is supplemented by numerical results focusing particularly on the quantitative welfare implications

time to build consumption complementarity and fiscal stimulus abstract we show that time to build which creates a time gap between government spending and the accumulation of public goods is an important element that weakens the effectiveness of fiscal stimulus in the environment where private consumption and public goods are edgeworth complements adding time to build to the model delays the timing of utility enhancing effects of an increase in government expenditure leading households to shift consumption from today to the future the expansionary effect of government spending is hence dampened which contrasts existing studies with edgeworth complementarity between private and public consumption

infrastructure and inequality abstract we develop a model in which public capital is both an engine of growth and a determinant of the distributions of wealth income and welfare government investment increases wealth inequality over time regardless of its financing the time path of income inequality is however highly sensitive to financing policies and is often characterized by sharp intertemporal tradeoffs with income inequality declining in the short run but increasing in the long run public investment generates a positive correlation between growth and income inequality along the transition path but their short run and long run relationship depends critically on i how externalities impinge on allocation decisions ii financing policies and iii the time period of consideration finally these policies also generate sharp trade offs between average welfare and its distribution with government investment improving average welfare but also increasing its dispersion our results are obtained numerically but extensive sensitivity analysis confirms their robustness across key parameter values

displaced populations humanitarian assistance and hosts a framework for analyzing impacts on semi urban households summary this paper presents a framework for understanding the impacts of civil war displaced populations and humanitarian assistance on host populations in semi urban areas our model shows that under conditions of conflict where populations flow from rural to urban areas and food aid follows changes in food housing and labor markets result in changes to local prices which will potentially impoverish consumers but provide earning opportunities for property owners and suppliers of non tradable goods and that the price dynamics are likely to induce significant land use change we combine satellite price aid delivery and population inflow data with qualitative interviews from nyala darfur the data confirm the hypotheses and the paper discusses possible policy responses

internal borders ethnic based market segmentation in malawi summary ethnic diversity is associated with poorer economic development but why i argue that market segmentation is one mechanism linking diversity to economic underdevelopment when ethnic groups are geographically segregated and trust is concentrated within groups markets will be tend to be segmented along ethnic lines i evaluate this argument using maize price data from seventy malawian markets over 14 years and combine it with census data on the spatial distribution of ethnic groups i find that maize price differences a key indicator of market segmentation are indeed larger for ethnically dissimilar markets even after taking sub national administrative borders geographic barriers and climatic differences into account these statistical findings are complemented by interview data from farmers and traders in three markets across malawi which highlight the centrality of trust in small scale maize trading as well as a preference for coethnic trading partners together these findings suggest that ethnic diversity and ethnoregional segregation in particular can have a negative impact on market integration an important driver of food security and long term economic development

public investment in infrastructure in a simple growth model abstract in this paper we examine the implications for capital accumulation when infrastructure enters as an external input into private production functions in our model infrastructure is nonexclusive but may exhibit varying degrees of nonrivalry revenues from uniform taxes on capital and labor income are used to finance public investment in infrastructure we show that the optimal tax rate is independent of the degree of nonrivalry when production exhibits constant returns to augmentable factors the equilibrium displays constant growth for most parameters the growth rate depends on the population size under decreasing returns the optimal trajectory exhibits monotonic convergence to a steady state level

unexpected guests the impact of internal displacement inflows on rental prices in colombian host cities abstract we study the causal impact of internally displaced people idp inflows on rental prices in colombian host cities following an instrumental variables approach we find that as idp inflows increase low income rental prices increase and high income rental prices decrease we provide empirical evidence on two potential mechanisms for these findings excess demand for low income housing puts upwards pressure on rental prices increasing supply of high income housing coupled with rising homicide rates put downwards pressure on rental prices

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

industrial policy choice during the crisis era using an extensive database of non macroeconomic state interventions implemented since the global economic crisis began this paper provides quantitative evidence on the resort to selectivity by several major economic powers the propensity to promote certain sectors certain firms within sectors and domestic over commercial interests is contrasted across jurisdictions at least one prominent contention in the industrial policy literature is not borne out in the data and certain cross country and cross sectoral variations found here could benefit from further analysis a crisis era shift towards selectivity and away from the level playing field can be detected in the major trading nations

the educational and professional background of central bankers and its effect on inflation an empirical analysis we assume that central banks can control inflation so that inflation rates reflect the preferences of the central bank council the hypothesis to be tested is that these preferences depend on the central bankers educational and or professional background in a panel data analysis for the euro area and eleven countries since 1973 we explain inflation either by the weights with which the educational and professional characteristics of the 391 council members were represented in the various central bank councils or by the education or profession of the median council members control variables are added using professional background weights we find that former members of the central bank staff and in some specifications former insurance executives commercial bankers other businessmen and public servants prefer significantly lower inflation rates than former union leaders and politicians do in the median voter analysis former central bankers commercial bankers businessmen and public servants are also significantly more inflation averse than economic scholars as for the education of the council members our results are less robust however if the median member of the central bank council has studied business the inflation rate is significantly lower than if she has studied economics taking educational and professional background together central banks seem to attract or produce primarily economists who are monetary conservatives whereas keynesian economists are more prominent in academia jel classification e42 e58

the benefit of crises for economic reforms when expenditures consistently outrun revenue the resulting inflation may have the effect of convincing the public and government that taxes must be raised to finance public investment in the advanced industrial countries income taxation and big spurts in taxation generally have become possible only under the impact of major emergency and crisis mostly in wartime in a number of developing countries in

why and when do governments initiate public enterprise reform initiating public enterprise reform is a complex decision influenced by economic factors as well as the ideological biases and personalities of political leaders nevertheless the use of a contracting framework yields important generalizations about what drives the decision this article argues that the decision depends fundamentally on the potential efficiency gains from the reform and its associated transactions costs costs arise because of asymmetries in information and opportunism problems that usually plague contract negotiations the article identifies observable variables that may affect either the potential gains or the transactions costs uses them to construct a simple probit decision making model and tests the model using data from fifteen developing countries over a twenty year period

transitional dynamics in two sector models of endogenous growth the steady state and transitional dynamics of two sector models of endogenous growth are analyzed in this paper we describe necessary conditions for endogenous growth the conditions allow us to reduce the dynamics of the solution to a system with one state like and two control like variables we analyze the determinants of the long run growth rate we use the time elimination method to analyze the transitional dynamics of the models we find that there are transitions in real time if the point in time production possibility frontier is strictly concave which occurs for example if the two production functions are different or if there are decreasing point in time returns in any of the sectors we also show that if the models have a transition in real time the models are globally saddle path stable we find that the wealth or consumption smoothing effect tends to dominate the substitution or real wage effect so that the transition from relatively low levels of physical capital is carried over through high work effort rather than high savings we develop some empirical implications we show that the models predict conditional convergence in that in a cross section the growth rate is predicted to be negatively related to initial income but only after some measure of human capital is held constant thus the models are consistent with existing empirical cross country evidence authors

long live democracy the determinants of political instability in latin america abstract we investigate the underlying causes of political instability in a panel of 18 latin american countries from 1971 2000 we test whether regime type regime durability factionalism income inequality ethnic diversity ethnic discrimination regional spillover effects urban growth and macroeconomic variables matter for instability we find several important results 1 democracy has a significant negative effect on instability that is robust to several alternative specifications 2 factionalised political systems experience higher instability 3 income inequality ethnic fractionalisation and urban growth have important nonlinear effects on instability and 4 of the macroeconomic variables we study only openness to trade has a significant negative effect on instability

the impact of forced displacement on host communities a review of the empirical literature in economics the paper reviews 49 empirical studies that estimate the impact of forced displacement on host communities a review of the empirical models used by these studies and a meta analysis of 762 separate results collected from them are the main contributions of the paper coverage extends to 17 major forced displacement crises that occurred between 1922 and 2015 to host countries at different levels of economic development and different types of forced migrants the focus is on outcomes related to household well being prices employment and wages all studies can be classified as ex post quasi natural experiments the analysis on empirical modeling shows a preference for partial equilibrium modeling differences in differences evaluation methods and cross section econometrics with all these choices largely dependent on the type of data available the meta analysis on household well being shows that between 45 and 52 percent of the results are positive and significant indicating a net improvement in household well being an additional 34 to 42 percent of the results are found to be nonsignificant and 6 to 20 percent show a decrease in household well being the analyses on employment and wages show positive and significant improvements for 12 to 20 percent of the results nonsignificant results in 63 percent of the cases and negative and significant results for 22 to 25 percent of the results negative results on employment and wages relate to young and informal workers in middle income countries the results on prices show asymmetric behavior across types of products overall the probability of having a negative outcome for host communities in the consumer and labor markets is below 20 percent

when do governments improve fiscal institutions lessons from financial crisis and fiscal reform in latin america do crises really lead to more institutional reforms this paper explores the connection between financial crises and one type of reform frequently advocated during the recent global financial crisis namely fiscal institutional reforms some authors expect that crises lead to reforms but we demonstrate that the relationship is not so straightforward using a data set of latin american countries that experienced several crises and also several periods of reform in the period from 1990 to 2005 we find that the type of crisis and its duration matter we argue that reforms are less likely during a banking crisis whereas fiscal crises are most likely to lead to fiscal reforms this means that the type of economic crisis is important for explaining the likelihood of reforms we explore other possible explanations for reform such as the partisanship of the president and whether a country is under an imf program and do not find confirming evidence for alternative explanations

the political economy of financial reform how robust are huang s findings using new data on financial liberalization taken from abiad et al 2008 imf working papers no 08 266 for 62 countries over the period 1975 2005 we show that some of the main findings of huang s 2009 journal of applied econometrics 24 1207 1213 replication study on the drivers of financial liberalization are not robust major changes concern the effect of democracy on financial reform and the supposed relationship between the desired level of financial liberalization and a country s per capita income copyright c 2012 john wiley sons ltd

why do crises go to waste fiscal austerity and public service reform in the tight budgetary conditions following the 2008 financial crisis governments have proposed saving money by reforming public services this paper argues that tight budget constraints make reform harder by introducing an information problem governments are uncertain about bureaucratic departments effectiveness normally effective departments can be identified by increasing their budget since they can use the increase to produce more than ineffective departments can when budgets must be cut however ineffective departments can mimic effective ones by reducing their output budget cuts thus harm both short run productive efficiency and long run allocative efficiency i confirm these predictions in a us dataset low marginal productivity bureaucracies reduce output by more than expected in response to a budget cut and budget setters respond less to observed short run marginal productivity after cutback years

spill over effects of supply side changes in a two country economy with capital accumulation abstract using a two country dynamic optimization model with capital accumulation we explore the effect of such supply side changes as a rise in productivity and a reduction in the corporate tax rate on the equilibrium path and the welfare of two countries the welfare effect consists of a tax distortion term and a wealth term those supply side changes in the creditor country increase its welfare but unambiguously decrease the debtor country s welfare as capital moves from the debtor country to the creditor country

does food aid really have disincentive effects new evidence from sub saharan africa summary limited empirical evidence exists either to refute or confirm the pervasive belief that food aid has significant disincentive effects on recipient food production using household level data from rural ethiopia we demonstrate that while simple descriptive statistics appear consistent with the disincentive effects hypothesis once one controls properly for the endogeneity of food aid receipt no empirical support remains for the hypothesis that food aid creates disincentive effects among recipient households the macro economic evidence yields similar findings applying vector autoregression methods to national level data controlling for possible confounding variables we find that food aid has no disincentive effect on food production

public investment congestion and private capital accumulation this paper analyses the impact of public investment on the dynamics of private capital formation in an intertemporal optimising market clearing framework the key feature characterising the analysis is that the public good is treated as a durable capital good subject to congestion we show how in the presence of congestion the effect of government investment on private capital formation involves a tradeoff between the degree of substitution between private and public capital in production and the degree of congestion both lump sum and distortionary tax financing are considered with this tradeoff being tightened in the latter case

economic reform and political transition in africa the quest for a politics of development the 1980s were bracketed by crises in africa as protracted economic malaise was succeeded by a wave of political reform analysts have sought to understand the sources of economic decline as well as the political requisites for recovery in the region neoclassical and structuralist analyses have been challenged by state centric views of economic change the latter perspective emphasizes the need for capable developmental states as a basis for long term adjustment but a political theory of economic change is still lacking such a theory must address the institutional foundations of growth as well as the shifting basis of social coalitions in african regimes political liberalization suggests the possibility of a new setting for economic reform though the effects of political reform on institutions and coalitions remain ambiguous and democratization cannot be regarded as a panacea for the region s developmental failure future research must look more closely at the interests and structures in transitional regimes and scholars should adopt a more comparative vantage on africa s challenges of reform

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

explaining african economic performance africa has had slow growth and a massive exodus of capital in many respects it has been the most capital hostile region we review and interpret the aggregate level and microeconomic literatures to identify the key explanations for this performance there is a reasonable correspondence of the two sets of evidence pointing to four factors as being important these are a lack of openness to international trade a high risk environment a low level of social capital and poor infrastructure these problems are to a substantial extent attributable to government behaviour and the paper includes a review of the political economy literature which addresses that behaviour

inflation s children tales of crises that beget reforms are broad reforms the children of high inflation do growth recoveries follow we find that countries that had external debt crises with high inflation both reformed more and recovered better than countries that had external debt crises with low inflation countries with extremely high inflation also later wound up with lower inflation than countries that has moderately high inflation the low inflation debtor countries had more aid than the high inflation debtor countries which may have created stronger incentives to reform in the high inflation countries recent reforms look like they are the children of high inflation even if further paternity tests are in order this abstract was borrowed from another version of this item

do crises induce reform a critical review of conception methodology and empirical evidence of the crisis hypothesis the notion that economic crises induce the adoption of reform ranks among the most widely accepted concepts in the political economics literature however the underlying mechanism of the so called crisis hypothesis has yet to be fully understood this paper provides a comprehensive survey of the relevant empirical evidence to date and scrutinizes the operationalization of the hypothesis key concepts crisis reform and the political mediation of reform during crises we argue that the social perception of both crises and the subsequent cost of reform requires consideration of how these concepts are operationalized as a product of the broader economic and institutional environment social perceptions largely determine the manner in which the political mediation of reform during crises works present day methodological approaches fail to adequately reflect social perceptions and consequently compromise the determination of what constitutes both crisis and the cost of reform in the context of the crisis hypothesis most notably the identification of crises by fixed thresholds constructed around macroeconomic variables impedes the interpretation of the hypothesis underlying mechanism a fuller treatment of social perception within the operationalization of the hypothesis key concepts can enhance our understanding of how economic crises influence political dynamics in bringing about reform

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

globalisation and policy effects in africa globalisation or market integration in sub saharan africa is closely linked to the structural adjustment programmes in this paper we focus on their dependence on the politics and institutional characteristics of the countries concerned in particular we argue that one important explanation for the dismal performance of many african countries in spite of all the measures taken towards market liberalisation is the combination of first a magnification of the effects of policy and second a lack of willingness or ability on the part of politicians to respect the restrictions imposed on their behaviour and policy choices by the liberalised markets we look at how the increased exposure to international prices and returns on assets make the economic equilibrium relations the law of one price and uncovered interest parity relevant guidelines for economic policy the argument is illustrated by the case of zimbabwe where lack of respect for the restrictions imposed by international markets has led to an economic crisis with negative growth rates and a departure from globalisation

the transitional dynamics of fiscal policy long run capital accumulation and growth this paper analyzes the effects of fiscal policies in a non scale growing economy with public and private capital the equilibrium dynamics are characterized and we contrast the dynamic effects of government expenditure on investment and expenditure on consumption under four alternative modes of tax financing most of our attention focuses on the numerical simulations of a calibrated economy the results emphasize the lengthy transition periods which implies that policies have sizeable level effects leading to substantial welfare effects even though long run growth rates are unaffected the paper highlights the intertemporal dimensions of fiscal policy and the tradeoffs these involve for economic performance especially growth and welfare

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

the composition of government expenditure and its consequences for macroeconomic performance abstract this paper employs the intertemporal optimizing market clearing framework to compare the effects of government consumption expenditure and government infrastructure expenditure on macroeconomic adjustment and performance particular attention is focused on the time path of the capital stock and its adjustment to both permanent and temporary changes in government expenditure are considered we show how the effects of both forms of government expenditure on economic welfare can be broken down into 1 i a direct crowding out effect and 2 ii a second component which describes the intertemporal tradeoffs between the short run rate of capital accumulation and the resulting change in the capital stock

optimal tax debt and expenditure policies in a growing economy abstract this paper employs an endogenous growth model to analyze the role of a consumption tax in enhancing growth and welfare provided government expenditure impacts directly on the decisions of private agents two fiscal instruments are necessary to replicate the first best optimum the tradeoff between consumption and income taxes to achieve this outcome is discussed and shown to depend upon the degree of congestion associated with the public good and the level of government expenditure relative to its social optimum in general the analysis suggests a potentially important role for a consumption tax as part of an overall optimal fiscal package

how effective is public health expenditure in improving overall health a cross country analysis the primary emphasis of this paper is on seeking some justification for the worldwide phenomenon of increasing government involvement in health care the disability adjusted health expectancy dale rankings of countries in the world health report 2000 ranked wealthier countries with a typically large public sector involvement in health care higher on the list contrary to the possible implications for this ranking this paper finds that the comparatively higher dale in wealthier countries is not a result of greater public health expenditures in the middle income and less developed countries however there is some evidence of effective public involvement in health care

solving the mystery of the africa dummy abstract most empirical studies have reported a negative effect on growth of being an african country even when accounting for ethnic heterogeneity modeling policy choices has reduced this effect in recent studies but these have begged the question of why africa appears adverse to developmental policies this paper uses a cross sectional data set to show that the governments of arbitrary postcolonial states as are most african states face substantial limitations to their power and are constrained in their responses deriving greater relative power payoffs from neo patrimonial than from developmental policies differing levels of state legitimacy account therefore largely for the policy choices which characterize most of africa

dynamic analysis of an endogenous growth model with public capital this paper develops an endogenous growth model with productive public capital along with private capital in a spirit similar to that of r j barro 1990 since the authors model includes two stock variables it has transitional dynamics unlike most of the previous studies on endogenous growth including barro s where concerns are restricted to the steady state analysis first they show that the transitional path is unique and stable second the character of the transitional path is explored third the authors show that the optimal tax rate is smaller than the rate that maximizes the national growth rate with a log linear utility function copyright 1993 by the editors of the scandinavian journal of economics

indeterminacy and endogenous growth with social constant returns abstract by examining endogenous growth models with physical and human capital this paper demonstrates that indeterminacy of equilibrium may emerge even in the absence of increasing returns to scale the model we examine consists of two production sectors one produces final goods and the other produces new human capital both sectors use physical as well as human capital it is assumed that while the private technology of the representative firm in each sector exhibits decreasing returns to scale the social technologies of both sectors satisfy constant returns because of the presence of sector specific externalities we demonstrate that a small divergence between private and social factor intensity conditions generates indeterminacy of equilibrium rather easily even under constant returns intuitive implications of the source of indeterminacy and a generalization of the model are also presented journal of economic literature classification numbers d90 o40 o41

qualitative and mixed methods research in economics surprising growth promising future qualitative research in economics has traditionally been unimportant compared to quantitative work yet there has been a small explosion in use of quantitative approaches in the past 10 15 years including mixed methods projects which use qualitative and quantitative methods in combination this paper surveys the growing use of qualitative methods in economics and closely related fields aiming to provide economists with a useful roadmap through major sets of qualitative methods and how and why they are used we review the growing body of economic research using qualitative approaches emphasizing the gains from using qualitative or mixed methods over traditional closed ended approaches it is argued that although qualitative methods are often portrayed as less reliable less accurate less powerful and or less credible than quantitative methods in fact the two sets of methods have their own strengths and how much can be learned from one type of method or the other depends on specific issues that arise in studying the topic of interest the central message of the paper is that well done qualitative work can provide scientifically valuable and intellectually helpful ways of adding to the stock of economic knowledge especially when applied to research questions for which they are well suited
