We study a model of endogenous growth where firms invest both in product and process innovations. Product innovations (that open up completely new product lines) satisfy the advanced wants of the rich. Subsequent process innovations (that decrease costs per unit of quality) transform the...

This paper presents a dynamic North-South general-equilibrium model where households have non-homothetic preferences. Innovation takes place in a rich North while firms in a poor South imitate products manufactured in the North. Introducing non-homothetic preferences delivers a complete...

This paper presents a dynamic North-South general-equilibrium model where households have non-homothetic preferences. Innovation takes place in a rich North while norms in a poor South imitate products manufactured in North. Introducing non-homothetic preferences delivers a complete...

This paper presents a dynamic North-South general equilibrium model with nonhomothetic preferences. Innovation takes place in the rich North while firms in the poor South at random imitate products manufactured in the North. The model is able to generate endogenous product cycles as described by...
