In this paper, we investigate the global dynamics of an endogenous growth model with linear technology and addictive habits. We find feasible parameters’ conditions under which: (a) the resulting equilibrium consumption path is steeper than in a standard AK model; (b) endogenous fluctuations...

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

The dynamic programming approach for a family of optimal investment models with vintage capital is here developed. The problem falls into the class of infinite horizon optimal control problems of PDE's with age structure that have been studied in various papers ([Barucci and Gozzi, 1998],...
