| This study uses household level panel data from Malawi to measure the contemporaneous and dynamic impacts of fertilizer subsidies on different indicators of household well‐being. Well‐being is measured in this paper using indicators contained in available survey data, such as area cultivated, maize production, asset wealth, respondent‐stated adequacy of food consumption and respondent-stated life satisfaction. The study uses fixed effects and instrumental variable methods to control for endogeneity caused by the non‐random distribution of targeted fertilizer subsidies. Results indicate that the quantity of subsidized fertilizer acquired by a household has a positive contemporaneous effect on area planted, area planted to maize and maize production at the... |

| The objective of this study is to identify the factors responsible for the impressive growth in fertilizer use in Kenya since market liberalization in the early 1990s. Over the past 10 years, fertilizer consumption has risen by 35%. So far, it is unknown whether smallholder farmers are responsible for this growth or whether it is being driven mainly by the large-scale and/or estate sectors. Moreover, it is important for policy makers to know whether the increased fertilizer consumption is being devoted to smallholder food crops or whether industrial crops such as tea and sugarcane are responsible for this growth. This study addresses these questions using nationwide survey data on smallholder fertilizer use patterns between 1996 and 2004. The study also... |

| Using a two-year panel of 1,422 Kenyan households surveyed in 1997 and 2000, we measure how prime-age adult mortality affects rural households' size and composition, agricultural production, asset levels, and off-farm income. First, the paper uses adult mortality rates from available data on an HIV-negative sample from neighboring Tanzania to predict the number of deaths that might have been expected in the absence of HIV, and compares this to the number of deaths actually recorded over the survey interval in the Kenyan sample. Based on this procedure, only a quarter of the prime-age female deaths in the 25-34 age range and about half of the male deaths in the 35-44 year age range age range could have been predicted on the basis of the HIV-negative... |

| This study was funded jointly by the Regional Strategic Agricultural Knowledge Support System (Re-SAKSS) for Southern Africa, based at International Water Management Institute, Pretoria, South Africa, and by the United States Agency for International Development's Africa Bureau. Much of the data and analysis reported in this study was carried out under the Tegemeo Agricultural Monitoring and Policy Analysis Project, funded by USAID/Kenya; the Food Security Research Project/Markets, Trade and Enabling Environment (MATEP) Program, funded by USAID/Zambia and the Swedish International Development Agency; and by the DFID and USAID offices in Lilongwe, Malawi. |

| This paper describes the different food policy courses pursued in recent years by four countries in Eastern and Southern Africa, and documents their differential effects on farmer and consumer behavior. Results are based primarily on a survey and synthesis of recent analysis. The paper highlights lessons learned from the different policy paths pursued in each country, and thus provides insights into the costs and benefits of alternative strategies for promoting national food security and enhancing producer and consumer options. |

| Multi-year nationwide survey data is used to estimate maize yield response functions and determine profitability of fertilizer use by small-scale farmers in Zambia. Most previous research on economics of fertilization used estimates of yield response to nutrients based on experimental or simulation data and seldom investigated region-specific and management-specific effects. In this paper we address the main issues arising from using large survey data and estimate maize yield response functions for different groups of households that have various management practices and soil conditions in two major agro-climatic zones. Profitability of fertilizer use is determined for each group in each zone and the results provide the following messages. First,... |

| This report is a synthesis of views presented at the Confronting the Silent Challenge of Hunger USAID Conference, June 28-29, 1994. The purposes of the conference were to provide information to assist AID in defining and articulating its development strategy related to agriculture and food security, to identify issues of consensus for incorporation into future AID strategy, and to identify critical issues of ongoing debate which need to be resolved. |

| This report reassesses the causal link between domestic agricultural policies and world price instability, using the case of the rice market. Specifically, the report develops a framework for analyzing the effects of domestic policies on international price stability, identifies the conditions required for government policies to destabilize world markets and econometrically examines whether these conditions apply to the trade behavior of seven major rice trading countries over the period 1960-87. This is done by comparing the estimated transmission and absorption effects with those implied under free trade, by incorporating several behavioral restrictions drawn from standard trade theory. Sensitivity analysis is then used to discern how robust the results... |

| Campaigns to prevent the spread of HIV require accurate knowledge of the characteristics of those most likely to contract the disease. Studies conducted in Sub-Saharan Africa during the 1980s generally found a positive correlation between socioeconomic characteristics such as education, income, and wealth and subsequent contraction of HIV. As the disease has progressed, the relationship between socioeconomic status and HIV contraction may have changed, although there is little evidence to support this. An emerging strand of the literature on the AIDS epidemic in Africa posits that poverty is increasingly associated with the spread of the disease. However, this conclusion is somewhat contentious, as other recent studies find mixed evidence of a poverty-AIDS... |
