Democracy and Economic Growth in an Interdependent World

We model dynamic interdependence in cross‐country economic growth processes by allowing it to vary according to democratic distance among economies. Stochastic distributional dynamics and temporal effects of democracy on economic growth are studied, and spatial variation in economic growth is explored. Among important results, democratic poverty trap is found to exist indicating the possibility of persistence of (un)stable democratic equilibria at different levels of democracy. Our cross‐sectional regression evinces that democracy has exerted significant growth‐enhancing effect and that the democratic distribution has steadily shifted locus from low‐level to high‐level equilibrium. Our spatial analysis of democracy‐economic growth nexus provide evidence of significant dynamic spatial autocorrelation and complementarity among countries' growth processes. Finally, it is demonstrated that the relevance of geographical proximity in facilitating interdependence in economic growth is overshadowed by relational proximity.     

TFP growth and its determinants: a model averaging approach

Total Factor Productivity (TFP) accounts for a sizable proportion of the income differences across countries. Two challenges remain to researchers aiming to explain these differences: on the one hand, TFP growth is hard to measure empirically; on the other hand, model uncertainty hampers consensus on its key determinants. This paper combines a non-parametric measure of TFP growth with Bayesian model averaging techniques in order to address both issues. Our empirical findings suggest that the most robust TFP growth determinants are time-invariant unobserved heterogeneity and trade openness. We also investigate the main determinants of two TFP components: efficiency change (i.e., catching up) and technological progress.     

The effects of health aid on child health promotion in developing countries: cross-country evidence

Although epidemiological knowledge in relation to child health has improved in the last few decades, around 3 million children die each year in developing countries from preventable diseases. The international development community views increased immunization coverage for children as an important step in eliminating or reducing these deaths. Many developing countries have very limited resources to tackle major health problems and have to rely on external finance. This article examines the impact of foreign aid devoted to the health sector on child health promotion in developing countries. Two proxies for child health promotion are used: (a) immunization against measles and (b) immunization against Diphtheria–Pertussis–Tetanus (DPT). A range of model specifications and panel data econometric techniques are applied to data covering the period 1990 to 2005. This article finds a positive and statistically significant link between health aid and the measures of child health promotion.     

Moral hazard and the composition of transfers: theory and evidence from cross-border transfers

We study how a donor can use restricted transfers to control the moral hazard behavior of a recipient and how the composition of unrestricted and restricted transfers is adjusted in response to changes in the moral hazard behavior of the recipient. Under certain conditions, our game-theoretic model predicts that the donor reduces the proportion of restricted transfers in total transfers as the moral hazard behavior of the recipient declines. Using foreign aid transfers (i.e., project aid and program aid) and panel data covering the period 1991–2007, we find econometric support for the prediction of the model. Our results suggest that some variables that affect the size of foreign aid may have no effect on the composition of aid.     

Impact of hurricanes strikes on international reserves in the Caribbean

ABSTRACT

In this study, we investigate the impacts of hurricane shocks on the international reserves of Caribbean countries. To this end, we use a panel VARX (Vector Auto-Regressive, with exogenous variables) with monthly data that allow us to account for external shocks (hurricane strikes). Our results show that for the whole sample, an increase in foreign reserves a month after the strike was followed by a decrease 2 months later. The increase can be explained by remittances and emergency foreign aid granted by the International Monetary Fund. Dividing the sample into middle-income and high-income countries shows that the increase is mainly due to the latter. This outcome may not be surprising given that production in Caribbean high-income countries is mainly due to manufacturing, off-shore banking and natural resources exploitation, which are all non-weather dependent sectors, while the middle-income countries are mostly dependent on weather-prone agriculture and tourism.     

Soil and cropping system research in semi-arid West Africa as related to the potential for conservation agriculture

Semi-arid West Africa faces challenges to increase sorghum and pearl millet production to meet food needs for a growing human population while increasing soil carbon (C), nutrient levels, and water holding capacity that are documented benefits of conservation agriculture. This review focuses on the wealth of research on cropping systems, tillage, crop residue, nutrient, and weed management as related to conservation agriculture. It also identifies needs for multidisciplinary, integrative research to assist the transition from current production systems to conservation agriculture. Crop residue use as livestock feed, or fuel are major constraints to adoption of conservation agriculture, which could be reduced by wood production in agroforestry systems, alternate energy sources, and increased forage supply. Crop residue and grain yields are related, thus improved crop, soil, water, nutrient, and weed management to increase grain yield would also increase the supply of crop residue with potential for ‘left over’ crop residue being available for soil mulching. Incorporating indigenous shrubs and/or cover crops could also increase crop residue supply. Species diversity can be increased through crop rotation, agroforestry, cover crops, and intercrops. Higher grain and stover yields and increased profit potential for resource-poor farmers in West Africa will be required before wide-scale adoption of conservation agriculture will be possible.     

Aid Disaggregation and the Public Sector in Aid-Recipient Economies: Some Evidence from Cote D'Ivoire

The present paper examines the impact of different aid types, namely project aid, program aid, technical assistance, and food aid on the fiscal sector of the aid‐recipient economy by using time‐series data for Côte d’Ivoire over the period 1975–99. Our empirical results show that when a single value (or aggregated) for aid is used, foreign aid is fully consumed in the case of Côte d’Ivoire. However, results obtained under the assumption of aid heterogeneity clearly suggest that the government responds differently according to the nature of the aid inflows. Our approach tries to illuminate the response of the aid‐recipient government to different categories of foreign aid inflows and the empirical findings clearly demonstrate the importance of the aid disaggregation approach for delving deeper into aid effectiveness issues.     

A re-examination of the savings displacement hypothesis

This paper re-examines the savings displacement hypothesis. It uses a new dataset that disaggregates aid into project aid, financial programme aid, technical assistance grants and programme food aid. When considering the whole sample of 97 countries, results obtained from estimating a savings function using the GMM-System approach to dynamic panel suggest that project aid flows are the only type of aid exerting a negative effect on domestic savings. The results also show that the effects of the different categories of aid on domestic savings vary across regions, thus highlighting the importance of regional disaggregation in cross-country studies. The author would like to thank Jean-Louis Grolleau at the OECD Credit Reporting System for his helpful advice and his encouragements during the construction of the disaggregated aid database used in this paper.     

Hurricane strikes and local migration in US coastal counties

We examine the effects of hurricane shocks on key migration variables in US coastal counties. Results show that hurricane strikes increase the outward migration rate and that these migrants were somewhat wealthier, but that there was no impact on inward migration.     

Aid,Policy and Growth: Does Aid Modality Matter?

This paper contributes to the empirics of aid and growth by investigating whether aid modality matters in explaining its effectiveness. For this purpose, we include the four main aid modalities (project aid, financial program aid, technical assistance grants, and food aid) as explanatory variables in an endogenous growth model. We find that project aid affects positively and significantly growth, albeit with diminishing returns. Our results also show that financial program aid generally impacts on growth negatively, while the impacts of technical assistance and food aid are statistically insignificant. Moreover, we find that climate-related conditions influence the effect of project aid. JEL no.  C2, F3
