*This paper focuses on the role played by remittances in constrained economies. We consider an overlapping generations economy in which households have access to International Capital Market and the possibility to borrow to finance children education in order to receive remittances. Following the literature, we assume that remittances relax borrowing constraints. These inflows may reduce or increase domestic savings and capital accumulation, according to the level of capital inflows constraint. Because of the OLG structure, the country may either be constrained or unconstrained in the long run. Remittances may make the initially constrained economy converging to the unconstrained steady state.
**Coralligenous habitats are endemic coastal Mediterranean habitats and among the most important sources of marine Mediterranean biodiversity. In order to highlight the contribution of those habitats to human well-being, we investigated the "ecosystem services" that they may provided in Marseille and Port-Cros areas. Due to the lack of dedicated literature, the study is based on an expert survey, using the Delphi method (questionnaire and focus group) and interviews. Among the 15 services investigated 3 were unanimously accepted, 7 mostly accepted, 3 highly uncertain and 2 refuted by our group of 43 experts. This work was a first step toward the economic valuation of ecosystem services provided by coralligenous habitats. Results are used to conduct a public survey to study the stated preference of local people on a bunch of services provided by coralligenous habitats.
