| In this paper, we use a vintage-capital model with risk of eviction to assess cocoa farmers' response to changes in their tenure security and to the introduction of a new, faster-maturing cocoa variety. The model is calibrated with data from Cameroon in calendar year 2000, and then used to simulate the effects of institutional and technical change on farmer welfare and deforestation rates. Our findings can be summarized in three points. First, improved tenure security over cocoa fields increases farmers' consumption and welfare, but at the expense of more deforestation. Second, the introduction of new cocoa varieties with faster maturity and higher input response also unambiguously raises farmers' consumption and welfare. Doing so increases deforestation... |

| This paper examines changes in agricultural productivity in 10 Subsaharan countries. The relative performance of agricultural sector was gauged using data envelopment analysis. From a panel data set of the 10 countries which included the 28-year period 1972-1999, mathematical programming methods were used to measure Malmquist indexes of total factor productivity. It was found that, during that period, total factor productivity have experienced a negative evolution in sample countries. A decomposition of those measures suggest that, most of the weak performance of factors productivity is attributable more to technological change than technical efficiency change. French-speaking countries better succeeded to raise their productivity than English-speaking... |

| This paper explores the motives for inter-household private transfers in rural Burkina Faso. Given the importance of private transfers in household income, quantitatively evaluating the response of private transfers to recipient incomes is informative for the design and the implementation of public interventions, such as policy alleviation programs, which often include transfer programs. To the extent that private transfers interact with public ones, the overall impact of public transfers might be offset, leaving income distribution unchanged. I use the transfers model proposed by Cox, and two national surveys from Burkina to test whether private transfers are motivated by altruism, exchanges or by risk sharing objectives. The econometric estimations... |

| Resource transfers among households have received considerable interest among economists in recent years. Two of the main reasons for the surge of interest in household transfers are the information on human nature conveyed by transfer behavior and the implication on income redistribution policy that private transfer might have. Empirical studies, however, provide mixed results on transfer behavior. This is because previous inquiries were confronted with several estimation issues and have focused on data from developed countries where private transfers are already small. This paper contributes to the literature on transfer behavior by using a multifaceted econometric approach to examine the motives of household transfers in Burkina, a low-income country... |

| This research uses field-level data from Burkina Faso to ask what determines farmers' investment in two well-known soil and water conservation techniques: field bunds (barriers to soil and water runoff), and microcatchments (small holes in which seeds and fertilizers are placed). Survey data for 1993 and 1994 are used to estimate Tobit functions, compute elasticities of adoption and intensity of use, perform robustness tests and estimate alternative models. Controlling for land and labor abundance and other factors we find that those who have more ownership rights over farmland, and who do more controlled feeding of livestock, tend to invest more in both technologies. The result suggests that responding to land scarcity with clearer property rights over... |

| This paper uses national survey data to estimate up-to-date private rates of return to education in Burkina Faso. Mincer earning regressions are fitted to wage data for women and men, and for public and private sector workers. The main results indicate that rates of return rise by level of education, and the public sector does not compensate female primary education. The findings suggest that current education polices which focus on increasing primary schooling supply be complemented with support for children, especially girls from resource constrained households to reach the secondary and tertiary levels. The estimated returns to education are strongly influenced by sample selection. For both men and women, failing to control for both selection in the... |
