In standard economic growth theory it is usually assumed that labor force follows exponential growth. That is not a realistic assumption. In this paper we introduce a generalized logistic equation (Richards law) that describes more accurately population growth. Then we analyze the neoclassical...

In this paper we introduce the concept of economic regime. We review the basic notions and different definitions of economic regime and regime switching to describe how these notions appear implicitly or explicitly in different areas of the economic literature. Then we introduce a method to...

Our concern in this work is to obtain conditions for the uniqueness of equilibria, with commodity bundles as consumption patterns which depend on the state of the world. In the first section we consider an economy with complete markets, where consumption spaces are a finite product of measurable...

The object of this paper is to show some examples of economies in which singular equilibria occur as a consequence of utility functions and where this equilibria play a crucial rolle to understand the behavior of the economy as a system. An economy will be called singular if little changes in...

This paper aims to consider the possibility that a natural monopoly is maintained as such in the long run as a result of increased productivity caused by technological change. In parallel, we will discuss the relevance of implementing policies to encourage competition and free entry, in branches...

Abstract The economy under study is populated by two types of firms (innovative and not) and two types of workers (skilled and unskilled). The aim is to develop a model that confirms the existence of complementarities between innovative firms (R&D activities) and skilled workers (human capital)...

We consider an economy with two types of firms (innovative and non-innovative) and two types of workers (skilled and unskilled), where workers' decisions are driven by imitative behavior, and thus the evolution of such an economy depends on the initial distribution of the firms. We show that...

We consider an extensive form game to analyze the interdependence between environmental protection of resources, the activities related with the tourism and the behavior of a local population. We answer two questions: 1) Suppose that the central planner invest in tourist activities, has he...

We analyze the main dynamical properties of the evolutionarily stable strategy ESS for asymmetric two-population games of finite size in its corresponding replicator dynamics. We introduce a defnition of ESS for two-population asymmetric games and a method of symmetrizing such an asymmetric...
