We claim that economic agents driven by imitative behavior may impact the industrial specialization of national economies. We use a simple two-country model, where workers and firms decide to be skilled (or unskilled) and innovative (or non-innovative). We show that comparative advantages and...

This work extends the Sard-Smale Theorem to maps between convex subsets of Banach spaces that may have an empty interior.

This paper provides an extended framework to study general equilibrium theory with commodity spaces possibly of infinite dimensions. Our approach overcomes some difficulties found in the literature since it allows the study of the equilibrium when consumption sets may have an empty interior. It...

In this short paper we analyze the impact of tourist demand in hotel rooms on the investment of hotels on environmental quality. We show that when income of the tourists increases, then to maintain the demand for rooms, the hotels must in-crease the investment on the environmental quality of the...
