understanding agricultural policy in africa the contributions of robert bates abstract robert bates s writings on the determinants of agricultural policy in africa employ rational choice and dialectical approaches to political economy this paper discusses some of the strengths and weaknesses of each and proposes an alternative dynamic approach to understanding both the limitations and the sources of agricultural policy with particular reference to kenya

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

sources of stagnation in sub saharan africa abstract this paper investigates the sources of economic stagnation in sub saharan africa during the 1970s several policy variables are considered as well as a set of environmental variables which include climate violence export prices and other exogenous factors the paper uses statistical analysis in an attempt to identify the relative importance of the policy variables and the environmental variables taken as groups it also seeks to identify particular policy variables which seem to have been most significant in determining growth outcomes the technique employed for investigation is reduced form econometric estimation in a preliminary analysis the impact of the international trade environment on average economic performance in africa during the period since independence is investigated the results suggest an extremely close relationship between movements in export prices and average performance throughout the 20 year period a second econometric exercise investigates the joint impacts of environmental and policy variables on growth in a cross section of african states since 1970 the spirit of the approach is exploratory and a relatively large number of variables are constructed and tested through multivariate analysis a primary finding is that the environmental variables seem to have had more impact on growth as a group than the policy variables this finding must be qualified however by the continuing lack of some important policy variables agricultural price data have not yet become available in sufficient quantity for cross section analysis nor have several important human resource variables and indices of the use of resources in the public domain among the policy variables which have been used for the analysis those identified with retrenchment during periods of declining commodity prices seem most significant primary among these are the real effective exchange rate and some measures of effectiveness in foreign exchange reallocation during periods when imports must contract severely in the final section of the paper the cross section results are used for a counterfactual analysis of the growth experiences of individual african states measures of growth opportunity cost are constructed which suggest the degree to which errors in management and uncontrollable circumstances have held states below their potential growth paths the results suggest that some success stories may owe much to good luck while some failures may well be due less to bad management than to adverse circumstances

why aren t countries rich weak states and bad neighbourhoods this article challenges a common viewpoint that the policy choices made by state leaders are central to explanations of economic growth it argues that there are two possible flaws in this viewpoint first that state leaders have a free choice in policy decisions second that it is policies that in large part determine growth rates using a set of variables designed to capture the weakness of the policy autonomy of the state and possible non policy influences on growth rates the article concludes that initial conditions are a better determinant of wealth and growth than free policy choice

agricultural distortions structural change and economic growth a cross country analysis taxing agriculture to mobilize resources for industrialization has been a widely used development strategy using novel cross country time series data sets with direct measures of agricultural taxation we examine how a policy bias against agriculture affects the speed of convergence in income per capita structural change and economic growth we find that distortionary agricultural policies in poor economies can account for the emergence of convergence clubs in our sample by significantly retarding their structural transformation and economic growth overall we find no evidence suggesting that policies that discriminate against agriculture have been beneficial for long term economic growth

unit roots and granger causality in the ems interest rates the german dominance hypothesis revisited abstract the aim of this paper is twofold first it shows that a sufficient conditions for unit roots found in ar systems to persist in var systems amount to granger non causality in any direction among the variables involved this implies that a necessary condition for the disappearance of one unit root in a var system implies granger causality in at least one direction b for first order models with non explosive variables granger causality is also sufficient for cointegration and c causality and cointegration inference are strongly affected by the omission of an important causing variable second our new analytical framework allows us to formulate and test several new variations of the so called german dominance hypothesis in a unified cointegrating framework which we define as strong semi strong and weak types 1 and 2 german dominance in addition we allow for the possibility that the dominant player may lie outside the ems so that we introduce and test the us dominance hypothesis

financing enterprise development in sub saharan africa this paper examines some critical gaps in the financial infrastructure in sub saharan africa which have contributed to the poor performance of productive investment by private agents it first analyses the performance of financial systems encompassing both formal and informal financial sectors in relation to the changing policy environment and key features of the financial market structure it then identifies those gaps in financial services that have been particularly detrimental to private investment enterprise growth and transformation finally the paper considers policy implications drawn from east asian experiences with respect to financial policies institutional arrangements and market integration measures for financing enterprise development copyright 2001 by oxford university press

the implications of mean variance optimization for four questions in international macroeconomics abstract the hypothesis of mean variance optimization has powerful implications transcending particular methods used for variance covariance estimation 1 for conventional estimates of risk aversion substitutability between domestic and foreign securities is close to perfect in the sense that risk premiums are small in magnitude a few basic points and thus cannot explain much bias in forward rates 2 nevertheless as long as risk aversion is not zero foreign exchange intervention still affects the level of the exchange rate proportionately at least to asset supply changes 3 current account deficits also have effects 4 finally dollar depreciation should not be accompanied by appreciation of the mark against the franc

capital controls and balance of payments crises abstract the theory of balance of payments crises shows that under perfect foresight a system of fixed exchange rate is not sustainable in the presence of diverging economic policies in this paper it is shown how and why capital controls succeed in maintaining the principle of a fixed but adjustable parity both cases of a devaluation and a revaluation are considered and a condition for a parity change to be credible is presented

towards a dynamic schumpeterian welfare economics knowledge plays an increasingly important role in shaping the dynamics of an economy a static paretian welfare economics is therefore inadequate and needs to be supplemented by a dynamic schumpeterian welfare theory a dynamic welfare economics acknowledges the role of knowledge and communication as knowledge develops cumulatively in a social environment knowledge may not be readily diffused or exchanged different costs of communication need to be considered each affecting the creation of new knowledge recent developments in intellectual property right ipr law are evaluated to determine the extent to which they affect communication costs and thus future economic welfare

learning to love the dutch disease evidence from the mineral economies abstract recent literature proposes that a booming minerals sector may not only lead to dutch disease effects it may also be a development curse mineral economy case studies have tentatively confirmed this recourse curse thesis this paper examines the long run economic and development performance of a more general grouping of mineral based economies and finds little corroborating evidence

monetary co operation and economic growth in africa comparative evidence from the cfa zone countries this article compares economic growth performance of ten african countries all members of the cfa monetary zone with that of 23 non zone sub saharan african ssa countries our descriptive results suggest that overall african economies have experienced similar growth trends which are higher in the 1970s than the 1980s however contrary to previous studies disaggregated comparison of the cfa with the ssa indicate that no significant growth differences exist between these economies moreover our empirical findings suggest that monetary expansion and capital formation have positive impacts on output growth whereas inflation and government spending show negative effects in sum although participating in a monetary union has not necessarily resulted in faster output growth it has enabled the cfa countries to better control price fluctuations and monetary expansion

paths to development is there a bangladesh surprise using aggregate indices of education health demographic and gender equality outcomes we empirically investigate the hypothesis that bangladesh achieved a higher level of social development compared with countries of similar level of per capita income stylized facts and cross country regression results support this hypothesis for a broad range of dimensions further tests show that such achievements do not simply reflect income mediated channels and social expenditure programs we conclude by speculating on the role of bangladesh s development to sustain the process of growth and on the role of governance and institutional quality for the nexus between growth and development

credit for what informal credit as a coping strategy of market women in northern ghana abstract this paper explores the use of informal credit as a strategy for managing risks by market women in northern ghana a broad concept of the costs of risk management strategies is introduced and encompasses both a time and monetary dimension based on qualitative data the analysis reveals that market women invest a considerable amount of time in maintaining complex networks of informal credit providers to ensure their access to credit once a shock occurs informal credit involves high transaction costs and prevents market women from growing out of poverty in the long term

private irrigation investment in colombia effects of violence macroeconomic policy and environmental conditions abstract this paper identifies and estimates the effects of several determinants on private investment in irrigation in colombia it attempts to quantify macroeconomic policy environment and violence variables that have been identified in previous studies as significantly affecting investment in agriculture in general and in irrigation in particular variables such as violence climate and governmental price and credit policies are used to explain changes in private investment in irrigation across regions and over time violence negatively affects private investment climate affects the investment such that in regions with favorable climate conditions investment in irrigation is less attractive and appropriate government crop price and credit policies promote investment in irrigation

buying sharing and renting information goods information goods such as books journals computer software music and videos can be copied shared resold or rented when such opportunities for sharing are present the content producer will generally sell a smaller amount at a higher price which may increase or decrease profits i identify three circumstances where profits increase 1 when the transactions cost of sharing is less than the marginal cost of production 2 when content is viewed only a few times and transactions costs of sharing are low and 3 when a sharing market provides a way to segment high value and low value users

the real exchange rate and macroeconomic performance in sub saharan africa abstract pooled time series and cross section data for 33 countries in sub saharan africa ssa confirm the negative relationship between the real exchange rate rer misalignment and economic performance economic growth imports exports saving and investment macroeconomic instability also slows growth and other indicators of performance higher levels of misalignment are accompanied by higher levels of macroeconomic instability both lower levels of rer misalignment and instability lead to better economic performance the edwards model of rer determination performs well for the region black market premia tend to show a greater degree of misalignment in rer than alternative measures

foreign aid and statehood in africa has foreign aid destroyed state institutions in africa african states depend on development assistance to conduct basic government operations yet few of these states are well governed or effective at providing public goods the two trends mounting foreign aid and static or diminishing state performance raise an obvious question is aid dependency contributing to misrule and state failure in africa many critics argue the two phenomena are related i find they are not my analysis fails to show a negative association between aid receipts and two measures of democracy and economic freedom instead the evidence is consistent with a small positive relationship between aid and these indicators of state performance since the international community seems bent on reducing foreign aid an important issue is how african states can maintain and improve their performance with less foreign assistance

trade reform aggregate investment and capital flight on credibility and the value of information abstract in this paper we demonstrate that uncertainty about future policy reversals coupled with irreversible investment confers an option value to foreign exchange and may lead to capital flight and a fall in aggregate investment after a trade reform the analysis focuses on the value of information and the credibility of the policy reform the conclusion points to a potential role for international institutions to prevent such problems

when should we use intellectual property rights the economic analysis of property rights proceeds in two steps the first distinguishes rival from nonrival goods the second contrasts the welfare effects of property rights for these two types of goods for rival goods strong property rights lead to efficient outcomes for nonrival goods property rights involve the trade off formalized by william nordhaus 1969 weak property rights lead to under provision strong property rights create monopoly distortions recent discussions of copyright protection for recorded music have obscured the underlying economic issues interested firms deny that music sharing will reduce the incentives for firms to release new recordings artists and recording companies never acknowledge the efficiency costs of prices that far exceed marginal cost it is left to economists with no stake in the outcome to clarify these issues full disclosure i have not consulted for anyone in the napster case the stakes in the battle over the music business are small enough to get lost in rounding

the advantage of tying one s hands ems discipline and central bank credibility abstract it is often argued that the ems is an effective disciplinary device for inflation prone countries in europe since it forces the respective policy makers to pursue more restrictive monetary policies than they would otherwise it is not clear however why these countries should submit themselves to such discipline this paper argues that to answer this question appropriately one must consider that ems membership brings potentially large credibility gains policy makers in inflation prone countries the reason is that not only it attaches an extra penalty to inflation in terms of real appreciation but makes the public aware that the policy maker is faced with such penalty and thus helps to overcome the inefficiency stemming from the public s mistrust of the authorities

governance and growth in sub saharan africa real income per head in much of sub saharan africa grew rapidly in the 1960s but faltered following the first opec oil price shock in 1973 74 and then stagnated or fell from the late 1970s to the early 1990s africa also saw a broad wave of authoritarian rule sweep the continent in the 1960s and early 1970s since 1990 however the african political landscape has experienced significant changes many in the direction of greater pluralism and democracy moreover where civil strife has been avoided africa has seen a broad tendency towards rapid growth for several years after 1995 this sequence of events suggests that political economy may offer useful perspectives on africa s growth record over the last several decades we begin with a summary of africa s growth patterns and the evolution of african political regimes we then examine models of authoritarian rule for insights into the conditions under which elites may sacrifice the general interest to extract rents and retain power or in which leaders may find ways of making growth enhancing policy politically acceptable it would be premature to conclude that africa s political reforms of the 1990s have helped to generate economic progress however we do believe that the increase in political pluralism in combination with greater unity among african aid donors bodes well for a continuation of africa s growth recovery

exchange rate stabilization in the erm identifying european monetary policy reactions abstract we develop the structural var models for european countries france denmark and germany during the erm period to examine the monetary policy reactions especially the within erm exchange rate stabilization in addition to analyzing the impulse responses and variance decomposition we present the full monetary reaction function in an interpretable manner without introducing additional assumptions the results suggest some asymmetry in exchange rate stabilization non german exchange rate stabilization is stronger than german exchange rate stabilization but do not support the hypothesis that german monetary policy was independent of the erm

how should structural adjustment programs be designed abstract more than seven years have elapsed since the onset of the generalized debt crisis of 1982 yet the affected countries have still not managed to stabilize their economies these countries must now attempt structural adjustment in the midst of pervasive macroeconomic and political instability structural adjustment packages should be designed with this reality in mind this paper argues that structural adjustment programs should strive for sustainability rather than the economic liberalization that they presently stress illiberal policies which do not damage overall macro stability are preferable to liberal policies which are inherently unsustainable or engender macro instability liberalization programs that are not sustainable are likely to bring few benefits but have high costs in terms of private investment the paper discusses some of the chief implications of this opinion for the design of adjustment programs

medium run adjustment under import compression macroeconomic analysis relevant for sub saharan africa abstract the dynamic small open economy model of kouri 1979 is modified to analyze the role of the foreign exchange constraint in import dependent economies typical for sub saharan africa structural adjustment and investment allocation are related to the sectoral balance between traded and protected goods the import compression policy of the region establishes a linkage between the export performance of the traded sector and the capacity utilization of the protected sector it is shown that the relationship implies possible contractionary effects of demand expansion since exports are crowded out and the import capacity is reduced a destabilizing downward growth spiral may follow policies modifying the excessive demand and the import dependency seem necessary to turn contraction into growth

avoiding the resource curse indigenous communities and canada s oil sands summary concerns about a resource curse in canada have been raised in response to rapid growth in the petroleum sector in northern alberta in previous research there has been little consideration of how symptoms of the resource curse are experienced and managed at a regional scale and by indigenous communities an analysis of effects and responses is offered using a natural financial human and social capitals framework without consideration of how to manage the symptoms of the resource curse oil and gas activity is likely to further disadvantage indigenous populations already living on the margins of canadian society

evaluating participation in african monetary unions a statistical analysis of the cfa zones abstract thirteen african nations are engaged in two monetary unions with france often referred to as the cfa zone despite the acknowledged benefits of zone membership a convertible currency pooled resources and greater monetary and fiscal discipline several observers have questioned whether particular aspects of the zone such as the lack of autonomy of the two central banks and the surrender of the exchange rate as a policy instrument have impeded its members growth this paper addresses that question by testing whether cfa zone countries had different gnp growth rates from selected comparator countries during 1960 1982 results show that cfa countries grew significantly faster than comparator sub saharan african countries but usually slower and often significantly so than the whole sample of developing countries when the comparison is made by subperiod before and after 1973 cfa countries performance vis a vis that of their comparators improved during the 1973 1982 period casting further doubt on the claim that the monetary union is not functioning adequately

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

private investment under uncertainty in ghana abstract ghana s economic recovery program saw considerable growth of the economy during 1985 1991 this commendable performance slackened after 1992 a fact which is attributable to poor private investment response following reform this article shows that the poor growth in private investment may be attributed to the perception of uncertainty in the political and economic environment since 1982 the uncertainty is derived from the low credibility of government as it has been unable to assure investors that earlier decisions that showed a bias against private wealth will not be repeated economic incentives arising from reforms do not provide guarantees against poor credibility

aid intensity in africa abstract aid to sub saharan africa ssa is falling rapidly after reaching historically high levels in the early 1990s we provide a critical review of aid data and place the resource intensity of current flows in crosscountry and intertemporal perspective aid to ssa is not unusually high given the structural characteristics of african countries but it rose more rapidly than predicted until the mid 1990s we introduce the concept of transactions intensity and show that by some measures the management costs accompanying each dollar of aid to africa are comparatively high

rational and self fulfilling balance of payments crises speculative attacks on a pegged exchange rate must sometimes occur ifasset price paths are to be free of abnormal profit opportunities suchattacks are fully rational as they reflect the market s response to aregime breakdown that is inevitable the authors shows that under someexpectations about policy balance of payments crises can also be purely self fulfilling events in such cases even a permanently viableregime may collapse and the economy will possess multiple equilibriacorresponding to different subjective assessments of the probability ofa crisis the behavior of the domestic interest rate will naturally reflect the possibility of a speculative attack copyright 1986 by american economic association

liberalisation and seigniorage revenue in kenya ghana and tanzania this article examines the implications for seigniorage revenue of exchange rate and asset market liberalisation it is argued that liberalisation lowers the average and marginal seigniorage capacity of governments by increasing the elasticity of substitution between base money and other financial assets moreover to the extent that exchange rate liberalisation eliminates goods market rationing it simultaneously reduces the return to holding precautionary and speculative money balances the implication is that countries that have relied on seigniorage revenue need to undertake deeper than anticipated fiscal adjustment in order to maintain macroeconomic balance following liberalisation programmes the article uses error correction estimates of the demand for base money to derive the long run revenue maximising rate of inflation for the three economies and to assess the revenue implications of the sluggish adjustment of money demand in response to short term monetary shocks

trade policy and growth of developing countries some new data abstract the present study provides empirical evidence on trade policy and economic growth of developing countries our data indicate that adverse changes in world demand carried greater weight in determining export performance than changes in trade policy the results presented confirm that high growth rates of export earnings occur only when external demand to strong low income countries are shown to fare worse across all time periods though there are regional variations these are not due solely to differences in trade policy thus an outward oriented policy is not necessarily a valid policy recommendation for all conditions and all countries

terms of trade fluctuations and stabilization of producer prices by compensatory taxation abstract a small general equilibrium model is presented which highlights the role of the real exchange rate in the south in determining the terms of trade between the south and the north the dynamics of the model may generate terms of trade instability for some values of the parameters of the system compensatory taxation of export earnings by a stabilization fund in the south is shown to increase the likelihood of instability

public expenditures in sub saharan africa during a period of economic reforms abstract public expenditure restraint is the most direct means of reducing balance of payments and budget deficits and is consequently a key aspect of macroeconomic adjustment programs the results of this study indicate a steady increase in total central government and social services spending during 1977 1989 in sub saharan africa the growth in population however contributed to an overall erosion in per capita expenditures while total government expenditures as a share of gdp have been stable during the past decade they have declined net of interest repayments which represent an increasingly large share of total spending an analysis of spending in the three years before and after donor financed adjustment programs began reveals no pattern of increase or decrease in real levels of total and social sector expenditures or in social sector spending as a share of the total expenditures elasticities of health and education spending with respect to gdp were found to be greater than unity in recent years indicating that as countries develop social spending will constitute a larger share of gdp

sociopolitical instability and the behavior of savings in less developed countries the paper argues for the introduction of sociopolitical instability as a factor in explaining saving behavior it also provides empirical evidence in regard to the quantitative and qualitative relationship between these two variables the empirical results point towards an inverse relationship between sociopolitical instability and savings our estimates are based on a sample of 7 observations from 60 countries a new pooling procedure is used to address the problems of autocorrelation and heteroskedasticity

asymmetric monetary policy effects in emu this paper develops a semi structural modelling approach to study asymmetric monetary transmission in europe a system of dynamic equations containing reaction functions for monetary policy as well as output gap and inflation equations is simultaneously estimated for france germany and italy we find asymmetries on the demand side in the strength of interest rate transmission and on the supply side in the effects of the output gap on inflation the responses are similar in germany and italy and generally stronger than in france out of sample tests do not find a structural break in the transmission mechanisms prior to the establishment of the european monetary union

politics and the effectiveness of foreign aid abstract critics of foreign aid programs have long argued that poverty reflects government failure in this paper i test predictions for aid effectiveness based on an analytical framework that relates aid effectiveness to political regimes i find that aid does not significantly increase investment nor benefit the poor as measured by improvements in human development indicators but it does increase the size of government the impact of aid does not vary according to whether recipient governments are liberal democratic or highly repressive but liberal political regimes and democracies ceteris paribus have on average 30 lower infant mortality than the least free regimes this may be due to greater empowerment of the poor under liberal regimes even though the political elite continues to receive the benefits of aid programs an implication is that short term aid targeted to support new liberal regimes may be a more successful means of reducing poverty than current programs

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

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

location taxation and governments an exchange theory of intellectual property abstract the standard economic model of intellectual property is an efficient property rights solution to a market failure problem of investment in a non rival and non excludable good we propose an exchange theory of intellectual property based on a contracting approach in the context of market making and enforcement of economic rights in exchange for monopoly taxation rights we use a hotelling 1929 type spatial model to show the relationship between location and pricing decisions of innovating firms under differing intellectual property institutional quality and taxation regimes

stock markets in africa emerging lions or white elephants abstract the number of stock markets in african countries has doubled over the last 7 years although these markets remain small and illiquid they are growing rapidly and will become an increasingly important part of many african economies using examples taken from experience in other developing regions and africa s recent past this paper evaluates the common economic criticisms of stock markets and the political pitfalls involved in their operation it concludes that the positive economic effects of bourses on african economies are far larger than any negative effects and argues that the political costs can be mitigated while political benefits can also be gained it finishes by suggesting reforms that can be put in place to reap more benefits and further reduce costs from stock markets on the continent

economic growth in africa abstract this paper draws on the recent endogenous growth methodology to study the factors behind differences in per capita growth rates across africa the results indicate that various economic factors including initial conditions investment population growth trade orientation inflation financial development and the growth of the government sector contribute significantly to economic growth in addition to economic variables we find the degree of political freedom to be a significant contributor to economic growth finally we find some evidence that economic growth by the members of the cfa franc zone has not fared well in comparison to other african countries
