On the strategic equivalence of multiple-choice test scoring rules
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2005-12)
A disadvantage of multiple-choice tests is that students have incentives to guess. To discourage guessing, it is common to use scoring rules that either penalize wrong answers or reward omissions. These scoring rules are ...
Estacionalidad determinista y estocástica en series temporales macroeconómicas
(2004-12)
Basándose en la literatura existente, en este trabajo se propone una metodología para el estudio gráfico y analítico del componente estacional en una serie temporal. El objetivo del análisis es determinar si el componente ...
International and Intergenerational Dimensions of Climate Change: North-South Cooperation in an Overlapping Generations Framework
(2003-12)
Global environmental problems such as climate change have both an international and an intertemporal dimension. Recently, some papers have used an overlapping generations framework to analyze the climate change problem ...
Do experimental subjects favor their friends?
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2005-06)
Ideally we would like subjects of experiments to be perfect strangers so that the situation they face at the lab is not just part of a long run interaction. Unfortunately, it is not easy to reach those conditions and ...
Union Formation and Bargaining Rules in the Labor Market
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2005-03)
This paper analyzes union formation in a model of bargaining between a firm and several unions. We address two questions: first, the optimal configuration of unions (their number and size) and, second, the impact of the ...
Should Fiscal Policy be different in a Non-Competitive Framework?
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2002-07)
This paper studies if imperfections in the labor market justify a different fiscal policy. We present a dynamic general equilibrium model with a Ramsey planner deciding about public spending, labor taxes and debt. Two ...
Optimal Fiscal Policy with Rationing in the Labor Market
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2002-07)
This paper characterizes the optimal fiscal policy when it is assumed that there exists a minimum wage below which no worker can be hired. The rigidity due to the minimum wage legislation can lead to equilibria in which ...
Admissible Hierachic Sets
(2005-05)
In this paper we present a solution concept for abstract systems called the admissible hierarchic set. The solution we propose is a refinement of the hierarchic solution, a generalization of the von Neumann and Morgenstern ...
The Supercore for Normal Form Games
(2003-10)
We study the supercore of a system derived from a normal form game. For the case of a finite game with pure strategies, we define a sequence of games and show that the supercore of that system coincides with the set of ...
Consumption-Leisure Trade-offs and Persistency in Business Cycles
(2007)
This paper studies whether nonseparabilities between consumption and leisure may help to explain the observed persistence in GNP growth. We consider an extended version of Lucas' (1988) human capital investment model that ...
