The VAR/SVAR (Vector Autoregressive and Structural Vector Autoregressive) models are the cornerstone of the contemporaneous empirical macroeconomic research, in particular for being able to measure the impact of fiscal policy shocks. They may be employed as atheoretical models, as well as a mean...

This study analyses the situation of the Brazilian population vis-à-vis the Social Security System (SSS) using data from PNAD. We chose the 1982, 1992 and 2002 PNAD data to give a series of pictures of the Brazilian population at equal intervals but under different legal instances with respect...

The paper analyzes the appointment of the European Commission as a strategic game between members of the European Parliament and the Council. The focal equilibrium results in Commissioners that duplicate policy preferences of national Council representatives. Different internal decision rules...

We study repeated prize allocation problem when the discount factors f the agents are not equal. It is shown that the feasible set of payoffs is not well behaved. In particular, it is not convex as it contains holes and caves. The Pareto frontier is everywhere discontinuous and there is an open...

This paper deals with the voting rules in the EU Council. Both internal and external impact of the voting rules are evaluated. Internal impact affects the distribution of power among the member states and external impact affects power relations between the main decision-making bodies in the EU....

We study the existence of pure strategy Nash equilibria in finite congestion and coordination games. Player set is divided into two disjoint groups, called men and women. A man choosing an action a is better off if the number of other men choosing a decreases, or if the number of women choosing...

Techniques based on using principal eigenvectors of matrices representing binary relations of sets of alternatives are commonly used in social sciences, bibliometrics, and web search engines. In most applications the binary relations can be represented by a directed graph and the question of...

We study iterated formation of mutually best matches (IMB) in college admissions problems. When IMB produces a maximal individually rational matching, the matching has many good properties like Pareto optimality and stability. If preferences satisfy a single peakedness condition, or have a...

We study a model of task completion with the opportunity to learn about own self-control problems over time. While the agent is initially uncertain about her future self-control, in each period she can choose to learn about it by paying a non-negative learning cost and spending one period. If...

This paper explores the impact of antiquity on capitalism through the finance-growth nexus. We define antiquity as the length of established statehood (i.e., state history) and agricultural years. We argue that extractive institutions and deeply entrenched interest groups may prevail in...
