Cooperative games in strategic form
Hart, Sergiu; Mas-Colell, Andreu - Department of Economics and Business, Universitat … - 2008
In this paper we view bargaining and cooperation as an interaction superimposed on a strategic form game. A multistage bargaining procedure for N players, the “proposer commitment” procedure, is presented. It is inspired by Nash’s two-player variable-threat model; a key feature is the...

Stochastic uncoupled dynamics and Nash equilibrium
Hart, Sergiu; Mas-Colell, Andreu - Department of Economics and Business, Universitat … - 2004
In this paper we consider dynamic processes, in repeated games, that are subject to the natural informational restriction of uncoupledness. We study the almost sure convergence to Nash equilibria, and present a number of possibility and impossibility results. Basically, we show that if in...

Assigning proctors to exams with scatter search
Ramalhinho-Lourenço, Helena; Martí, Rafael; Laguna, Manuel - Department of Economics and Business, Universitat … - 2001
In this paper we present an algorithm to assign proctors to exams. This NP-hard problem is related to the generalized assignment problem with multiple objectives. The problem consists of assigning teaching assistants to proctor final exams at a university. We formulate this problem as a...

Iterated local search
Ramalhinho-Lourenço, Helena; Martin, Olivier C.; … - Department of Economics and Business, Universitat … - 2000
Iterated Local Search has many of the desirable features of a metaheuristic: it is simple, easy to implement, robust, and highly effective. The essential idea of Iterated Local Search lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the...

Exploiting fitness distance correlation of set covering problems
Finger, Markus; Stützle, Thomas; Ramalhinho-Lourenço, … - Department of Economics and Business, Universitat … - 2001
The set covering problem is an NP-hard combinatorial optimization problem that arises in applications ranging from crew scheduling in airlines to driver scheduling in public mass transport. In this paper we analyze search space characteristics of a widely used set of benchmark instances through...

Does eeasoning enhance learning?
Vriend, Nicolaas J. - Department of Economics and Business, Universitat … - 1996
Utilizing the well-known Ultimatum Game, this note presents the following phenomenon. If we start with simple stimulus-response agents, learning through naive reinforcement, and then grant them some introspective capabilities, we get outcomes that are not closer but farther away from the fully...

Falling real wages during an industrial revolution
Ciccone, Antonio - Department of Economics and Business, Universitat … - 1996
The Industrial Revolution was characterized by technological progress and an increasing capital intensity. Why did real wages stagnate or fall in the beginning? I answer this question by modeling the Industrial Revolution as the introduction of a relatively more capital intensive production...

On Rothschild-Stiglitz as competitive pooling
Martin, Alberto - Department of Economics and Business, Universitat … - 2003
Dubey and Geanakoplos [2002] have developed a theory of competitive pooling, which incorporates adverse selection and signaling into general equilibrium. By recasting the Rothschild-Stiglitz model of insurance in this framework, they find that a separating equilibrium always exists and is...

Geographical effects on the accuracy of textile trade data:an international approach for 1913
Carreras, Anna - Department of Economics and Business, Universitat … - 2005
Foreign trade statistics are the main data source to the study of international trade. However its accuracy has been under suspicion since Morgernstern published his famous work in 1963. Federico and Tena (1991) have resumed the question arguing that they can be useful in an adequate level of...
