In this paper, we apply SAM linear models to the economy in a Spanish region, Extremadura, from the usual household disaggregation of these matrices. The analysis aims to some issues related to income distribution. To achieve these goals, some relative multipliers are computed and we propose...

The paper lists salient characteristics of the certainty theory of consumer choice and discusses the import of prominent empirical analyses of the theory. All of them reject the theory's empirical relevance which suggests that the theory is unfit to analyze consumer choice in an uncertain world....

Kazimierz Łaski's first contributions to economics were on the theory of growth and equilibrium in the socialist economy. He gravitated in between Włodzimierz Brus, who argued that the economy could be brought into equilibrium through market mechanisms, and the most profound influence on...

Economic modeling struggles often with a lack of realism. The reason for that is that economic theory for the last 100 years has focused on simplifying assumptions which reduced important aspects of the economic reality. Concentrating on fix-point solutions and external statistical shocks...

The paper begins with a figurative representation of the contrast between present-day and formal applied econometrics. An explication of the status of bridge principles in applied econometrics follows. To illustrate the concepts used in the explication, the paper presents a simultaneous-equation...

Migration has been a difficult phenomenon to measure because of its volatile characteristics and the number of models that explain the essential incentives of the process. In Bolivia there are few quantitative studies of international migratory movements, however, there are records that reflect...

For any emission trading system (ETS) with quantity-based endogenous supply of allowances, there exists a negative demand shock, e.g. induced by abatement policy, that increases aggregate supply and thus cumulative emissions. We prove this green paradox for a general model and then apply it to...

We take for granted that the basic choice in public policy is between allocation of resources by government bureaucracy, on the one hand, or allocation by markets, on the other. But that dichotomy is false, and at least under contemporary circumstances it is more accurate to describe the choice...
