We study the compatibility of the optimal population size concepts produced by different social welfare functions and egalitarism meant as "equal consumption for all individuals of all generations". Social welfare functions are parameterized by an altruism parameter generating the Benthamite and...

This paper quantitatively investigates the short- and long-run effects of liberalizing global migration on the world distribution of income. We develop and parametrize a dynamic model of the world economy with endogenous migration, fertility and education decisions. We identify bilateral...

The empirical analyses show that public and private R&D are strongly intertwined. On the one hand, the existence of large direct spillovers from public R&D to private industry has extensively proven. Yet, both a substitutability and complementarity relationship between private and public R&D...

A prediction of the endogenous growth models with quality ladders is that there exists a negative relation between growth and the degree of market competition. The aim of this article is to shed light on the relation between competition and growth when horizontal and vertical innovations can...

In this paper, we solve a Solow model in continuous time and space. We prove the existence of a solution to the problem and its convergence to a stationary solution. The simulation of various scenarios in the last section of the paper illustrates the convergence issue

The aim of this paper is to understand the role of uncertainty in education choices and therefore in growth. We consider an overlapping generations model in which endogenous growth is introduced through human capital accumulation. We introduce uncertainty as to the individual returns to...
