In a realistic framework where the potential innovators’ research lines are imperfectly correlated and imitation takes some time, this paper studies an industry regulated by an authority which can tax (subsidize) the firms’ pure profits (R&D expenditures). By comparing the market equilibrium...

The use of the K-functions (Ripley, 1977) has become recently popular in the analysis of the spatial pattern of firms. It was first introduced in the economic literature by Arbia and Espa (1996) and then popularized by Marcon and Puech (2003), Quah and Simpson (2003), Duranton and Overman (2005)...

This paper shows that two societies differing because of the people’s initial propensity to devote time and efforts to non-profit activities may never converge. This lack of convergence is interpreted as the tendency of the cultural values and attitudes dominant in each society to perpetuate...

Compliance with a social norm is a matter of self-enforceability and endogenous motivation to conform, which is relevant not just to social norm,s but also to a wide array of institutions. Here we consider endogenous mechanisms that become effective once the game description has been enriched...

The two-country growth model developed in this paper incorporates home production and distinguishes between a market sector producing services that can also be home-produced and a market sector producing goods without home-produced substitutes. This distinction coincides in the model with the...

This paper deals with the estimation of the lognormal-Pareto and the lognormal-Generalized Pareto mixture distributions. The log-likelihood function is discontinuous, so that Maximum Likelihood Estimation is not asymptotically optimal. For this reason, we develop an alternative method based on...
