Return migration in Italy: what do we know?

Return migration is the positive counterpart of brain drain. Human capital accumulation increases in a country if skilled agents go back home after a period spent working abroad. Effects of brain drain in Italy could be negative as highly skilled migrants decide not to come back to their native country. Our simple model shows that if preference for home consumption is balanced by career opportunities and life-style conditions, agents leave Italy and prefer to remain abroad. Data support and policy implications are provided.Return migration; brain drain.

Perfect Information vs Random Investigation: Safety Guidelines for a Consumer in the Jungle of Product Differentiation

We present a graph-theoretic model of consumer choice, where final decisions are shown to be influenced by information and knowledge, in the form of individual awareness, discriminating ability, and perception of market structure. Building upon the distance-based Hotelling's differentiation idea, we describe the behavioral experience of several prototypes of consumers, who walk a hypothetical cognitive path in an attempt to maximize their satisfaction. Our simulations show that even consumers endowed with a small amount of information and knowledge may reach a very high level of utility. On the other hand, complete ignorance negatively affects the whole consumption process. In addition, rather unexpectedly, a random walk on the graph reveals to be a winning strategy, below a minimal threshold of information and knowledge.Comment: 27 pages, 12 figure
