"In this paper we look at migration as a family decision of risk-sharing. The theoretical model is based on the maximisation of a joint utility function under a budget constraint which depends on the decision taken. To assess its relevance, an empirical version of this dichotomous model is estimated. Evidence from [an Ivory Coast case study] confirms some traditionally looked-at motives for migration and supports the idea of risk-sharing behaviour." (SUMMARY IN ENG)
