After a brief survey of the literature about the existence of a Nash Equilibrium in the class of the nonatomic games, we prove the existence of an equilibrium in the class of the nonatomic games where the players' payoff depends over the average strategy of finitely many convex and disjoint...

Previous research has found that immigration benefits the health of working-age natives, an effect mediated through the labor market. We use the Study of Health, Ageing and Retirement in Europe (SHARE) to investigate whether immigration also affects the health of natives 65-80 years old....

Using Italian data on standardized test scores, we show that the substantial heterogeneity in how performance changes with the position of questions can alter the rank of individuals and classes as the length of the test increases. We examine whether decomposing test scores into initial...

Using Italian data on standardized test scores, we show that the performance decline associated with question position is heterogeneous across students. This fact implies that the rank of individuals and classes depends on the length of the test. Longer tests may also exhibit larger gaps between...

We estimate the effect of the high school curriculum (or track) on the returns to college using data from the Italian PLUS (Participation Labour and Unemployment Survey) survey. We find that college graduates with vocational high school are less likely to be employed than graduates with academic...

In spite of their relative vicinity Scandinavian countries and Central European countries (mainly Germany) have substantially different schooling institutions. While the former group of countries delays school tracking until age 16, the latter group anticipates differentiation between age 10 and...

In this paper we argue that the incentive scheme faced by scientists induces them to promote their activity, publishing on-line their work-in-progress, participating or organising meetings and so on. Such actions produce a huge amount of externalities that may make easier for others to deal with...

Motivated by anecdotal as well as econometric evidence from Italy, we ask whether private schools can provide lower quality than public schools. Using a stylized model of the education market with sequential entry of a public and a private school, we show that, depending on the underlying...

The paper studies, in a repeated interaction setting, how the presence of cooperative agents in a heterogeneous community organized in groups, affects group efficiency and stability. The paper extends the literature by assuming that each type can profitably mimic other types. It is shown that...
