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...

A large population plays a two-period sequential common agency game. Agents are long lived, while principals are short lived. Preferences and technology are additively separable in time and time independent. At the onset, agents are matched in pairs under private information of individual types....

The "Retired Husband Syndrome", that affects the mental health of wives of retired men around the world, has been anecdotally documented but never formally investigated. We use Japanese micro data and the exogenous variation generated by the 2006 revision of the Japanese Elderly Employment...

We use data from a nationally representative survey of Italian graduates to study whether Alma Mater matters for employment and earnings three years after graduation. We find that the attended college matters, and that there are important college related differences, both among and within...

Does the peer effect vary with the field of study? Using data from a middle-sized public university located in Southern Italy and exploiting the random assignment of first year students to college accommodation, we find that roommate peer effects for freshmen enrolled in the Hard Sciences are...

In a multisector economy with unionized labor markets, the interdependence of union wage claims - typical of industrial bargaining - affects the relationship between tax progressivity and wage pressure, which varies in a nonlinear fashion with the nature of the wage bargain, and can be...

I use the cross-country and time variation in the demographic structure of 11 European countries to study how changes in cohort size affect real earnings in Europe. This is an important question in the light of widespread population ageing. I find that cohort size has a negative and...

In this paper we use British data to ask whether local employment density - which we take as a proxy of labor market competition - affects employer - provided training. We find that training is less frequent in economically denser areas. We interpret this result as evidence that the balance of...

We use data from the European Community Household Panel to investigate the impact of body weight on wages in 9 European countries. When we pool the available data across countries and years, we find that a 10% increase in the average body mass index reduces the real earnings of males and females...

In this paper we use a search and matching model to investigate the economic relationship between training and local economic conditions. We identify two aspects of this relationship going in opposite directions: on the one hand, the complementarity between local knowledge spillovers and...
