| Trade in ivory is banned under CITES in an effort to protect the African elephant. The trade ban is supported by some range states, most notably Kenya, because they see the ban as an effective means for protecting a ‘flagship’ species, one that attracts tourists and foreign aid. It is opposed by some states, mainly in southern Africa, because their elephant populations are exceeding the capacity of local ecosystems with culling and other sources have resulted in the accumulation of large stocks of ivory. They argue that ivory trade will benefit elephant populations. The question of whether an ivory trade ban will protect elephant populations is addressed in this paper using a dynamic partial-equilibrium model that consists of four ivory exporting regions... |

| During recent two decades the world has witnessed a drastic increase in global FDI inflows. Gradually more and more investment has been directed to the developing countries in the attempt to diversify portfolios and use finance in the most efficient way. Not all developing regions of the world perfectly succeeded in attracting FDI. Large by labor force and territory, abundant in natural resources Sub-Saharan Africa could perform much better in this aspect. This paper once again reviews the opportunities for FDI in Africa and suggests possible ways for authorities of African states to overcome the existing situation. |

| A standardized precipitation index is used in a regression analysis to quantify the impact of climate change on agricultural productivity in Sahel. I first estimate a Malmquist productivity index and its efficiency and technical change components. I further assess the statistical significance of the indices by estimating some confidence intervals via a bootstrap method. In the second stage of the analysis, I use a Probit model to estimate the extent to which climate variables affect agricultural productivity. It appears that agricultural performance has been disastrous in many Sahelian countries from 1970 to 2000. Using a comparable cross-country measure of drought, I provide evidence that precipitation variability is constraining not only Sahel’s... |

| In Tanzania, as in many other developing countries, the conventional wisdom is that economic reforms may have stimulated economic growth, but that the benefits of this growth have been uneven, favoring urban households and farmers with good market access. This idea, although quite plausible, has rarely been tested empirically. In this paper, we develop a new approach to measuring trends in poverty and apply it to Tanzania in order to explore the distributional aspects of economic growth and the relationship between rural poverty and market access. We find that, between 1991 and 2003, a period of extensive economic reforms, the overall rate of poverty fell about 9 percentage points. The degree of poverty reduction was similar between rural and urban areas,... |

| Zambia's strong dependence on copper exports has suppressed other tradables sectors, indicative of a Dutch disease phenomenon. The current copper crisis will have strong economic effects, possibly reversing such Dutch disease effects. We use a computable general equilibrium model built around a 1995 social accounting matrix to simulate the short- and long-run effects of two scenarios that reflect the current crisis, a 20 percent reduction in world copper prices and a complete collapse of copper mining. Compared to the short run, the long run is characterized by more flexibility in production technology and capital allocation. Both scenarios require a significant reduction in the "non-copper" trade deficit, absorption, and household consumption. The... |

| This paper reviews the literature on the impact of ethnic diversity on economic development. Ethnically polarized societies are less likely to agree on the provision of public goods and more likely to engage in rent seeking activities providing lower levels of social capital. Initial conditions are important determinants of adverse development outcomes. The role of decentralization, democracy and markets as potential remedies are discussed. The paper then presents a number of preliminary hypotheses on the relationship between diversity and instability in order to stimulate future research. |

| This study applies panel data techniques to investigate the long-run relationship between energy consumption and GDP for a panel of 19 African countries (COMESA) based on annual data for the period 1980-2005. In the first step, we examine the degree of integration between GDP and energy consumption by employing three panel unit root tests and find that the variables are integrated of order one. In the second step, we investigate the long-run relationship between energy consumption and GDP. Results overwhelming show that GDP and energy consumption move together in the long-run. In the third step, we estimate the long-run relationship and test for causality using panel-based error correction models. The results indicate that long-run and short-run causality... |

| Much has been written to show the importance of diversification for rural African households because of the considerable share of non-farm revenues in total income (Reardon, 1997; Reardon et al., 1998). The literature points out push and pull factors explaining that risk and adverse shocks which characterize farm activities urge rural population to diversify into more profitable non-farm activities. But less attention has been paid to the distinction between two diversification patterns, namely local diversification and migration, and their relationship. Drawing on the theoretical and empirical literature, we identify the advantages and drawbacks of local diversification versus migration decision in terms of expected pay-offs for the family and the... |

| An important feature of aid to developing countries is that it is given to the government. As a result aid has the potential to affect budgetary behaviour. Although the (albeit limited) aid-growth literature has addressed the effect of aid on policy, it has tended to neglect the effect of aid on the fiscal behaviour of governments. While fiscal response models have been developed to examine the effects of aid on fiscal aggregates - taxation, expenditure and borrowing - the underlying theory is ad hoc and empirical methods used are subject to severe limitations. This paper applies techniques developed in the "macroeconometrics" literature to estimate the dynamic structural relationship between aid and fiscal aggregates. Using vector autoregressive methods,... |

| Access to public and private health insurance in rural areas of low income countries is severely constrained by high unit cost of transaction per contract due to information asymmetries between insurance sellers and buyers. This leads to a situation in which the majority of the poor have to rely on out-of-pocket expenditures when they are ill, resulting in a high vulnerability for health shocks which negatively affect the overall risk management of the household, investment and resource allocation decisions. Recently, however, in various parts of the world community based health insurance schemes have emerged and are becoming increasingly recognized as an instrument to finance health care in poor developing countries. These mutual insurance schemes often... |
