Transient Health Shocks and Agricultural Labor Demand in Rice-producing Households in Mali

Malaria and other transient illnesses have been recognized as factors constraining economic development in tropical countries. The purpose of this paper is to determine the direct and the indirect impact of transient illness shocks, caused primarily by malaria but also including other tropical illness, on family labor use in irrigated rice production in Mali. Family labor is the most important factor of production used in rice production in Mali and transient illness shocks may negatively impact labor supply, production and hence household welfare derived from agricultural income and consumption. Two labor demand models are estimated to determine whether illness does indeed reduce labor supply: one where the dependent variable only includes family labor and a second that combines family and hired labor. These models can be used to test two sets of hypotheses on the relationship between illness and labor supply. First, we hypothesize that short-term transient illness shocks affect household labor supply implying that intrahousehold coping mechanisms are not wholly effective. Secondly, we hypothesize that hired labor markets are ineffective in mitigating illness shocks. We find that direct and indirect health shocks reduce the effective supply of labor and that neither household nor market supply of labor can mitigate these shocks.

The effect of climbing bean adoption on the welfare of smallholder common bean growers in Rwanda

This paper assessed the effect of climbing bean adoption on the welfare of the bean growers in Rwanda, using four indicators: per capita consumption expenditure, poverty head count, quantity of bean consumed per person and food security. The analysis was based on cross sectional data from a nationally representative survey of bean growers, conducted in 2011. Instrumental variables and control function approaches were used to address the endogeneity of climbing bean adoption decisions in household welfare outcomes. Results demonstrated that investments in climbing bean research and dissemination efforts contributed significantly to improve household welfare. One additional kilogram of climbing bean seed planted raises per capita consumption expenditure by 0.9% and that of bean consumption by 2.8%, and increases the probability that a household is food secure by 0.6% while decreasing the likelihood of being poor by 0.6%. These findings highlight the important role climbing bean adoption can play in reducing food insecurity and poverty in land constrained areas.

Schooling Achievement among Rural Zimbabwean Children during a Period of Economic Turmoil

Zimbabwe suffered severe economic crisis in the decade before 2009, and anecdotal evidence indicates that public education suffered due to uncertainty about salary payments and inflation. As the country recovers, it is important to understand how this crisis affected schooling participation before and during the crisis. This study focuses on the relationship between schooling achievement, measured by enrollment and enrollment in the age-appropriate grade, and household economic conditions in rural Zimbabwe for 2001 and 2007. A wealth index is used to reflect household economic conditions. Results indicate that children in the bottom 20 percent of the economic status distribution were less likely than others to be enrolled or attend the age-appropriate grade in both periods, but the impact of the crisis on indicators of school attendance are surprisingly modest. Findings indicate that the economy may be poised to rebound as macro-economic conditions stabilize since schooling attainment did not slip substantially.
