Willingness to contribute labor and money to tsetse control: application of contingent evaluation in Busia District, Kenya

Export citation

A household survey was conducted in six villages of Busia District Kenya to assess people's willingness to contribute labor and money to control the tsetse flies that transmit trypanosomiasis. A Heckman's two-step model was estimated to identify factors affecting the probability that a respondent was willing to contribute labor or money and the factors affecting the amounts of labor or money he or she was willing to contribute. Everything else equal households willing to contribute the most money were those whose heads were female and well educated while those willing to contribute the most labor were headed by men had high cash income and had participated in an educational event.
