A neoklasszikus közgazdaságtan hívei az általános egyensúlyelmélet Debreu-féle modelljére a gazdaságelmélet csúcsaként tekintenek. Tanulmányom célja az elmélet módszertani hátterének és tapasztalati relevanciájának vizsgálata, különös tekintettel az axiomatikus...

The present work intends to bring few clarifications, hopefully useful, in the general problem of economic competition. As it is probably already known by the reader, most of the XXth century studies on this subject are almost mysteriously dominated by the neoclassical writers\\\'s (leaders...

School choice plans in many cities grant students higher priority for some (but not all) seats at their neighborhood schools. This paper demonstrates how the precedence order, i.e. the order in which different types of seats are filled by applicants, has quantitative effects on distributional...

We introduce a general framework to analyze the trade-off between education and family size. Our framework incorporates parental preferences for birth order and delivers theoretically consistent birth order and family size effects on children's educational attainment. We develop an empirical...

The aim of this article is to demonstrate that the conclusions drawn by Samuelson’s marginal discrete analysis in his 1939 seminal paper “Interactions between the Multiplier Analysis and the Principle of Acceleration” concerning the equilibrium conditions of real national income in a...

This paper introduces and develops the concept of “conditional agreement point”, defined as the dominating issue (hard optimality) within a certain restricted subset of the set of feasible issues (partial optimality). Such a concept associates individualistic independence (via the operation...

This paper presents a stochastic dynamic general equilibrium model calibrated for Venezuela that incorporates inter-sectorial relationships. With this model it is possible to assess the impact on the aggregate economic activity generated by productivity shocks or demand shocks to a specific...

It is shown that, in pure exchange economies, the individual demand functions can be recovered from the equilibrium set regardless of the way we evaluate wealth. Following Balasco (2004), the demand functions do not have to be differentiable, not even continuous nor utility maximizing. Thus, the...

We consider a model with an finite number of states of nature where short sells are allowed.

Eleven percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used one quarter of the time. A choice-theoretic general equilibrium search model is constructed to analyze the Malawian epidemic. In the developed framework, people select...
