This paper presents an overlapping generations model with endogenous fertil
ity and human capital accumulation. Within such a framework, it shows how t
he presence of family-size norms can lead to multiple equilibria. It can th
us potentially explain different development patterns without recourse to i
ncreasing returns and differences in initial conditions. Furthermore, it de
rives sufficient conditions under which different equilibria can be Pareto
ranked. Finally, it shows that the main results hold also in the case where
there exists parental altruism. (C) 2001 Elsevier Science B.V. All rights
