In this article, within the framework of the General Equilibrium Theory, we present a model of evolutionary economy, with I consumers and N companies located in M different interrelated productive markets, in which the production decisions of the managers of the firms are the engine of the...

In this article, we consider a neoclassical production economy in which, unlike the generally static classical approach, we assume that, in response to technological change, the productive sector modifies -evolves- over time. We will analyze how this change affects economic welfare. We will show...

Standard decision theory encodes preferences as a complete, transitivepreorder predefined in a set of alternatives.In this paper we consider changes in preferences in pure exchange economies.We will analyze the repercussions of these changes on the economic structure,particularly on the set of...

In this paper we analyze the rationality that sustains the public investments on white elephants applied to the construction of tourist facilities in Mexico. The main result of this paper is that there exist two kinds of rationalities in the construction of white elephants. One is a similar...

In this paper we show that in a pure exchange economy where social weights and total resources are fixed there is no possibility to improve the social welfare by means of efficient reallocations of the resources. However, if social weights are not fixed but can be selected from a particular set,...

In standard economic growth theory it is assumed that labor force follows exponential growth, a not realistic assumption. As described in [4] the growth of natural populations is more accurately depicted by a logistic growth law. In this paper we analyze how the Ramsey growth model is affected...

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

In this paper we model tourism in the framework of multi-population dynamics and analyze the time pattern of its development through the evolving interaction between two populations feeding on a common space-resource. Each population might be structured in two (or more) "clubs" of members...
