We develop a general-equilibrium model to capture key features of the retailing and of the manufacturing industry in order to understand how these two industries interact and how labor is allocated between them. We show that the observed shift in employment from manufacturing to retailing, the...

My model embeds a novel, highly tractable and scalable demand system...

This paper develops a two-country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than...
