This paper asserts that the endowments of production factors cause cross-country differences in GDP per capita by generating disparities in the sectoral composition. For that purpose, we characterize the dynamic equilibrium of a two-sector endogenous growth model with many consumption goods that...

When habits are introduced multiplicatively in a capital accumulation model, the consumers' objective function might fail to be concave. In this paper we provide conditions aimed at guaranteeing the existence of interior solutions to the consumers' problem. We also characterize the equilibrium...

We analyze the welfare properties of the competitive equilibrium in a capital accumulation model where individual preferences are subjected to both habit formation and consumption spillovers. We also discuss how consumption externalities and habits interact to generate an inefficient dynamic...
