This paper proposes and evaluates area index-based financial contracts for specific farm activities. These financial contracts allow not only for removing moral hazard and adverse selection as index insurances do, but also for adding more flexibility and, hence, better risk protection. The...

We provide a normative analysis of endogenous student and worker mobility in the presence of diverging interests between universities and governments. Student mobility generates a university competition effect which induces them to overinvest in education, whereas worker mobility generates a...

Recent empirical evidence links migrant remittances, savings and return migration, and stresses the inaccuracy of return migration plans. This paper presents a model of endogenous remittances, savings and return decisions under uncertainty. In our framework, migrants make remittance and saving...

We provide a normative analysis of endogenous student and worker mobility in the presence of diverging interests between universities and governments. Student mobility generates a university competition effect which induces them to overinvest in education, whereas worker mobility generates a...

We present a theory of endogenous formation of insurance groups which combines heterogeneity on agents' risk aversion under asymmetric information and lack of enforceability of contracts. Income sharing inside the group is decided by majority voting and the size of the group adjusts to this...

The African cash crop sector has witnessed widespread liberalisation reforms aimed at strengthening price incentives to farmers. However, some areas are confronted with a decline in input use. We have recourse to a two-stage Cournot game to account for the issue. In a context of credit rationing...

As in the case of agricultural cooperatives, collective fields in extended agricultural households act as an insurance device, by redistributing income between household members. At the same time they entail inefficiencies arising from the incentives to free ride on co-workers efforts....

This paper presents a non-cooperative model of intra-household decision-making regarding investment in migration. It is shown that the combination of liquidity constraints and imperfect commitment are a source of underinvestment in migration. More precisely, we highlight that, if remittances are...
