competing models of international lending activity abstract four competing models of the world bank s lending to developing countries are constructed and econometrically estimated by pooled time series and cross section data the analysis suggests that a model combining economic and political determinants performs best besides per capita income inflation balance of payment and budget deficit external debt and past growth political determinants such as the capitalist climate or political instability are also important as well as a recipient country s former status as a colony or dominion this politico economic model is successfully used to forecast the distribution of ibrd loans and ida credits among the developing countries

technology adoption under seed access constraints and the economic impacts of improved pigeonpea varieties in tanzania dry land legumes well adapted to drought prone areas have largely been neglected in the past despite the good opportunities they offer for income growth and food and nutritional security for the poor this study evaluated the adoption and impact of two farmer and market preferred and disease resistant pigeonpea varieties that were developed and promoted in semi arid tanzania the new varieties were resistant to fusarium wilt a fungal disease devastating the crop however farmers wanting to adopt new varieties did not adopt due to seed access constraints and under developed seed delivery systems adoption of new varieties is therefore analyzed using an augmented double hurdle model that allows estimating variety adoption conditional on seed access thresholds accounting for the additional information on sample separation the study identifies the crucial role of seed access local supply extension education participatory decision making capital and household assets in determining adoption the social economic benefits of the technology and policies for improved seed access were further analyzed using the extended economic surplus method dream model even under restrictive assumptions overall discounted benefits were found to be quite attractive indicating the need for additional efforts to scale up the success story analysis of changes in research benefits from relaxing the seed access constraint showed that net gains would increase by up to 30 if farmer access to improved seeds can be assured smallholder farmers are the major beneficiaries along with consumers and rural net buyers who gain from productivity induced lower market prices

aid policy and growth in post conflict societies countries emerging from civil war attract both aid and policy advice this paper provides the first systematic empirical analysis of aid and policy reform in the post conflict growth process it is based on a comprehensive data set of large civil wars and covers 27 countries that were in their first decade of post conflict economic recovery during the 1990s the authors first investigate whether the absorptive capacity for aid is systematically different in post conflict countries they find that during the first three post conflict years absorptive capacity is no greater than normal but that in the rest of the first decade it is approximately double its normal level so ideally aid should phase in during the decade historically aid has not on average been higher in post conflict societies and it has tended to taper out over the course of the decade the authors then investigate whether the contribution of policy to growth is systematically different in post conflict countries and in particular whether particular components of policy are differentially important for this they use the world bank policy rating database the authors find that growth is more sensitive to policy in post conflict societies comparing the efficacy of different policies they find that social policies are differentially important relative to macroeconomic policies however historically this does not appear to have been how policy reform has been prioritized in post conflict societies

the sensitivity of returns to research calculations to supply elasticity returns to research are thought to be robust under alternative supply elasticity assumptions we show both conceptually and numerically how advances in approximating social benefits make returns to research sensitive to the supply elasticity despite this greater sensitivity these advances retain conceptual and practical advantages we make recommendations for dealing with the increased sensitivity copyright 2002 oxford university press

does being an imf executive board member re pay an examination of imf loans and repayments this paper analyses the political economy of imf loans and repayments using data from 99 countries over the period 1984 2014 we bring two contributions to the literature analysing i the impact of the presence of a country on the imf executive board and ii repayment behaviour and not only loan requests we show evidence that loans from and repayments to the imf are influenced by the presence of countries on the imf executive board in particular the results indicate that a position on the board increases the loan amount by approximately 0 5 points and the repayment amount by approximately 0 2 points

the reciprocal relationship between state defense interest and committee representation in congress does prior representation of a state on a congressional defense committee lead to higher levels of per capita defense contracts or do higher levels of prior per capita contract awards to a state increase its probability of being represented on a defense committee to solve this puzzle we estimate a cross lagged three equation model on data from all 50 states from 1963 to 1989 using maximum likelihood within lisrel we find a substantial reciprocal but non confounding relationship between representation and the allocation of benefits for the house but not for the senate thus for the house this more appropriate model of distributive politics in congress supports both the committee induced benefits hypothesis and the recruitment hypothesis further the paper elaborates on how this reciprocal relationship plays out over time

corporate governance at the world bank and the dilemma of global governance most major decisions at the world bank are made by its board of executive directors while some countries enjoy the opportunity to serve on this powerful body most countries rarely if ever get that chance this gives rise to the question does board membership lead to higher funding from the world bank s two main development financing institutions the international bank for reconstruction and development ibrd and the international development association ida empirical analysis shows that developing countries serving on the board can expect more than double the funding from the ibrd as countries not on the board in absolute terms countries on the board receive an average 60 million dollar bonus in ibrd loans an amount that rises in years when ibrd loans are in high demand particularly for countries in the most influential seats this effect is more likely driven by informal rules and norms in the boardroom than by the power of the vote itself no significant effect is found in ida funding these results point to challenges of global governance through representative institutions

regime linkages in the us uk real exchange rate real interest differential relation abstract using a multivariate regime switching framework and focusing on the period 1921 2002 which is characterized by different nominal exchange rate regimes and monetary regimes we find supportive evidence of the us uk real exchange rate real interest differential relation in terms of volatility regime dependence the two variables are jointly characterized by high volatility during periods of floating exchange rates and by low volatility during periods of fixed exchange rates thereby suggesting that the nominal exchange rate regime is the driving force behind the volatility regime switching thus allowing for regime switching in the real exchange rate real interest differential relation bridges the gap between popular theories of real exchange rate determination which predict such a relation and previous empirical studies which failed to uncover such a relation for the us uk real exchange rate

does delegation of fiscal policy to an independent agency make a difference evidence from intergovernmental transfers in india abstract one area of fiscal policy in which several countries have delegated responsibility to an independent agency is the distribution of national resource transfers across regional and local governments such delegation is expected to promote equity and efficiency and mitigate distortions created by political incentives this paper tests whether delegation to an independent agency indeed makes a difference by contrasting the impact of partisan politics on two types of fiscal transfers to states in the indian federation over a period of time 1972 1995 the pattern of evidence shows that while the transfers that are determined by the central political executive are indeed distributed to favor particular states that are politically important for the central ruling party the transfers that are delegated to an independent agency serve to constrain such partisan impact

ex ante analysis of the benefits of transgenic drought tolerance research on cereal crops in low income countries this article develops a framework to examine the ex ante benefits of transgenic research on drought in eight low income countries including the benefits to producers and consumers from farm income stabilization and the potential magnitude of private sector profits from intellectual property rights iprs the framework employs country specific agroecological drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits representing 40 of total benefits across the eight countries further estimated annual benefits of us 178 million to the private sector suggest that significant incentives exist for participation in transgenic drought tolerance research

why conditional aid does not work and what can be done about it abstract this paper studies a simple reform that introduces ex post incentives for the donor to reward good policies contrary to existing practices instead of committing aid to each recipient ex ante and making aid conditional on reform the donor centralizes the disbursement decision by committing aid to a group of countries the actual amount disbursed to each individual country would depend on its relative performance this explicit linkage of the allocation and disbursement decisions has two important advantages as compared to present practices first it raises the opportunity cost of disbursing aid ex post thereby giving the donor stronger incentives to reward good policies second competition among recipients allows the donor to make inferences about common shocks which otherwise conceal the recipient s choice of action this enables the donor to give aid more efficiently

the political economy of imf lending in africa why has imf lending achieved such poor results in africa is it because the fund imposes the wrong conditions or because it fails to enforce them analysis of monthly data on 53 african countries from 1990 to 2000 shows that the imf s loans for reform contract lacks credibility because donor countries intervene to prevent rigorous enforcement countries that have influence with developed country patrons as measured by u s foreign aid membership in postcolonial international institutions and voting profiles in the un are subject to less rigorous enforcement shorter program suspensions they have more frequent program suspensions because they violate their conditions more often the imf will have to become more independent in order to become an effective champion of reform

us politics and world bank ida lending this paper studies the role of us political factors in the allocation of world bank concessional lending where us political interests are proxied by voting similarity in the united nations general assembly on issues identified as important by the us department of state in contrast to previous studies we find that the us exerted a significant influence on ida lending during the period 1993 2000 we demonstrate that the influence was both statistically as well as economically significant finally we demonstrate that our result is robust with respect to the omission of the ida country performance rating index

the perversity of preferences gsp and developing country trade policies 1976 2000 industrial countries maintain special tariff preferences namely the generalized system of preferences gsp for imports from developing countries critics have highlighted the underachieving nature of such preferences but developing countries continue to place the gsp at the heart of their agenda in multilateral negotiations what effect do such preferences have on a recipient s own trade policies the authors develop and test a simple theoretical model of a small country s trade policy choice using a dataset of 154 developing countries from 1976 through 2000 they find that countries removed from the gsp adopt more liberal trade policies than those remaining eligible the results corrected for endogeneity and robust to numerous alternative measures of trade policy suggest that developing countries may be best served by full integration into the reciprocity based world trade regime rather than continued gsp style special preferences

potential impacts of bt eggplant on economic surplus and farmers health in india in this article the potential impacts of bt eggplant technology in indian agriculture are analyzed several proprietary bt hybrids are likely to be commercialized in the near future based on field trial data it is shown that the technology can significantly reduce insecticide applications and increase effective yields comprehensive farm survey data are used to project farm level effects and future adoption rates simulations show that the aggregate economic surplus gains of bt hybrids could be around us 108 million per year consumers will capture a large share of these gains but farmers and the innovating company will benefit too as the company has also shared its technology with the public sector bt open pollinated varieties might become available with a certain time lag this would make the technology more accessible especially for resource poor farmers entailing further improvements in welfare and distribution effects the wider implications of the private public technology transfer are discussed furthermore the potential benefits for farmers health resulting from reduced insecticide applications are examined using an econometric model and a cost of illness approach these benefits are worth an additional 3 4 million per year yet they constitute only a small fraction of the technology s environmental and health externalities more research is needed for comprehensive impact analysis

on us politics and imf lending abstract the political factors shaping imf lending to developing countries have attracted attention in recent empirical work this goes in particular for the role and influence of the us however scant formal modelling makes interpretation of empirical results difficult in this paper we propose a model in which the us acts as principal within the imf and seeks to maximize its impact on the policy stance of debtor countries we derive an optimal loan allocation mechanism which leads to the testable hypothesis that the probability of an imf loan is increasing in the amount of political concessions countries make a political concession is defined as the distance between a country s bliss point and its actual policy stance measured relative to the us we introduce a bliss point proxy and demonstrate that our hypothesis is strongly supported in the data moreover we show that not accounting for bliss points may lead to endogeneity bias in empirical work

rational expectations econometric analysis of changes in regime an investigation of the term structure of interest rates abstract this paper is of interest both for its methodological contribution of new tools for analyzing rational expectations models and for its substantive conclusions concerning the term structure of interest rates during the monetary experiment of october 1979 the paper studies systems subject to changes in regime interpreted here as occasional discrete shifts in the parameters governing the time series behavior of exogenous economic variables the specification is shown to be quite tractable both theoretically and empirically the technique is used to analyze yields on three month treasury bills and ten year treasury bonds during 1962 to 1987 a constant parameter linear model for short term rates is shown to be inconsistent both with the univariate time series properties of short rates and with the observed bivariate relation between long and short rates under the expectations hypothesis of the term structure an alternative nonlinear model that admits the possibility of changes in regime affords a much better description of the univariate process for short rates moreover the cross equation restrictions implied by the expectations hypothesis of the term structure are consistent with the nonlinear specification indeed the residuals of the restricted relation have a standard error of only 0 8 basis points this is a third less than that of a completely unrestricted linear regression of long rates on short rates and compares with an unconditional standard deviation of long rates of 142 basis points i conclude that once the recognition by bond traders of changes in regime is taken into account the expectations hypothesis of the term structure of interest rates holds up fairly well for these data

inducing efficiency in the use of foreign aid the case for incentive mechanisms in this article we point out that one of the main problems in foreign aid allocation is the efficient use of these funds as resources available for foreign aid are intrinsically scarce their efficient use would be in the interest of donors and especially recipient countries the aim of this paper is to show how it is possible to design incentive schemes which by relating the allocation of aid to the way it is used may induce the recipient country to use these resources appropriately we discuss potential benefits and problems of different contractual forms showing how comparing the performances of different countries may help to design optimal incentive mechanisms finally we illustrate a proposal of performance conditioning of the grant element which may help in tackling the efficiency problem

bt cotton in india field trial results and economic projections abstract the performance of bt cotton in india is analyzed on the basis of field trial data from 2001 the amounts of pesticides applied during the trials were reduced to one third of what was used in conventional cotton while under severe pest pressure yield gains were 80 productivity effects are modeled econometrically with a damage control specification the first approval for the commercial cultivation of bt hybrids was given in 2002 by 2005 the technology is expected to cover one quarter of total indian cotton area medium term projections show sizeable welfare gains for the overall economy with farmers being the main beneficiaries

news droughts news floods and u s disaster relief this paper studies the influence of mass media on u s government response to approximately 5 000 natural disasters occurring between 1968 and 2002 these disasters took nearly 63 000 lives and affected 125 million people per year we show that u s relief depends on whether the disaster occurs at the same time as other newsworthy events such as the olympic games which are obviously unrelated to need we argue that the only plausible explanation of this is that relief decisions are driven by news coverage of disasters and that the other newsworthy material crowds out this news coverage

regime dependence mrs machlup s wardrobe and the accumulation of international reserves in asia abstract an old yet rarely explored motive of hoarding international reserves advanced by machlup 1966 is examined reserve accumulation behavior in asia is driven by a psychological desire to keep up with neighboring countries i e keeping up with the joneses effect

the political economy of conditionality an empirical analysis of world bank loan disbursements abstract traditional aid conditionality has been attacked as ineffective in part because aid agencies notably the world bank often fail to enforce conditions this pattern undermines the credibility of conditionality weakening incentives to implement policy reforms the standard critique attributes this time inconsistency to bureaucratic factors within the aid agency such as pressure to lend defensive lending or short sighted altruism pressure from powerful donors provides another potential explanation for lax enforcement this paper presents an empirical analysis of the political economy of conditionality in international organizations using the case of the world bank and the united states the analysis examines panel data on world bank disbursements to 97 countries receiving structural adjustment loans between 1984 and 2005 using un voting as an indicator of alignment with the u s the paper presents evidence that world bank structural adjustment loan disbursements are less dependent on macroeconomic performance in countries aligned with the united states
