The general theory of election is the foundation of microeconomic theories relating to producer's and consumer's choice. In this document, I will argue in a simple form and didactics, the basic propositions of theory of election. I will expose simple examples of life daily, such that the...

In this paper we explore the minimization of expenditure, less important theorems of this approach, which must be met given the conditions of the preferences and the budget set. We will study the conditions of constraints of the demand, relating them to the different elasticities of Marshallian...

In this paper we develop the theory of uncertainty in a context where the risks assumed by the individual are measurable and manageable. We primarily use the definition of lottery to formulate the axioms of the individual's preferences, and its representation through the utility function von...

This paper will develop the half variance approach,identifying the expected utility functions that can be expressed in terms of the expected value and standard deviation. We study the stochastic dominance to determine the conditions required by the ordering of lotteries when they are probability...

This paper will discuss the classical theory of income developed by David Ricardo to understand not only its origin, also the role it plays in the stagnation of capitalist development. Also, since it will clarify the factors behind economic surplus allocation between social classes. In our...

In the present document we will sell off a brief exposition about the method of Economics, utilizing the classification proposed by Nicholas Georgescu - Roegen based in the logical sorting of propositions that they conform the economic science. Furthermore, we will discuss the perspective of...

In the present paper will work analytically the category of economic surplus. It will use the theoretical framework of technology system developed by Leontief to expose a clear form as to distinguish it from other concepts such as the net product.

The consumer’s theory is a particular case of the theory of choice. This paper will explore the fundamental propositions that explain the behavior of a consumer agent and then be expressed in terms of the function of utility. Thus, the concept of utility is divorced of any philosophical and...

This paper presents an analysis of Ricardo - Torrens model of comparative advantage. The contribution of this work is to make explicit the productive structure of the economy under analysis with the help of input-output matrix and the theoretical assumption of a Leontief technology system, which...

This paper presents the rationale of comparative statics shows the relationships established between important concepts, such as abstract process, cause-effect assumptions, the static economic equilibrium and comparative statics. In turn, presents these categories from the perspective of the...
