We analyse whether migration is an adaptation that households employ to cope with climate in Ghana and Nigeria. If … migration is part of the present adaptation portfolio of households in developing countries, it is reasonable to expect that it … generated by General Circulation model reveal that, ceteris paribus, migration may decline in Ghana and in Nigeria. …

This paper tries to explain why most migration flows show some observable jumps in their processes, a phenomenon that … seems to be sympathetic with the characteristic of irreversibility of migration. We present a real option model where the … probability of being fully integrated into the host country. The theoretical results show that the optimal migration decision of a …

Option Theory, investigates the roots of the migration dynamics. In the model the decision to migrate of each individual … observable "jumps" in the migration flows and to describe how the trigger for entry can change depending on the dimension of the …

This work is devoted to study the role of combined entry and exit strategies in the migration process. We develop a … triggers the migration choice, while the second triggers the return to the country of origin. The theoretical results show that … in some cases we observe migration inflows with a low wage differential and also with underunemployment. We show also …

We analyze the efficiency of urbanization patterns in a dynamic model of endogenous urban growth with two sectors of … equilibrium, compared to the efficient urbanization path, if economic growth implies increasing aggregate emissions. If, on the … other hand, production becomes cleaner over time (`quality growth') the urbanization path approximates the efficient outcome …

Over the last few years, environmental issues have entered into policy design, particularly development and growth … determinant. The integration of environmental issues into economic growth and development theories and empirics is currently … widely analyzed in the literature. The effects of natural resources endowment on economic growth are mainly analyzed through …
