Marcella Veronesi (University of Verona) Crop diversification and child health : Empirical evidence from Tanzania


Abstract :


Malnutrition is recognized as a major issue among low-income households in developing countries with long-term implications for economic development. Recently, crop diversification has been recognized as a strategy to improve nutrition and health, and as a risk coping strategy used by farmers in the face of climate change. However, there is no systematic empirical evidence on the role played by crop diversification in improving human health. We use the Tanzania National Panel Survey to investigate the effects of crop diversification on child health. We use fixed effects panel estimation to control for unobserved heterogeneity, and perform several robustness checks including placebo tests to test the validity of our findings. We find a positive and significant effect of crop diversification on long-term child nutritional status, in particular for very young children and children living in households with limited market access.


Emmanuelle Lavaine (Université d’Annecy) The Risks of Pollution and the Costs of Misperceptions


Abstract :


This paper estimates the change in averting behavior following the opening of residual waste plants in Mexico in the period 2000 to 2011. The theoretical averting behavior model, with a constant measure of utility, shows firstly that the difference in willingness to pay between two different perceptions of a risk can be attributed to preventive behavior. Following an environmental change which does not entail any health risks, the theoretical model allows curative and preventive health care to be differentiated skill-fully. Empirical results of the difference-in-difference model show households increase their bottled water spending even if the health risks of drinking contaminated tap are close to zero. Household income and education levels play an important role in the demand for health care and bottled water.
