When redistribution leads to regressive taxation
HARITON, Cyril; PIASER, Gwenaël - Center for Operations Research and Econometrics (CORE), … - 2004
We introduce labor contracts, in a framework of optimal redistribution: firms have some local market power and try to discriminate among heterogeneous workers. In this setting we show that if the firms have perfect information, i.e, they perfectly discriminate against workers and take all the...

ACOCELLA, Nicola; DI BARTOLOMEO, Giovanni; HUGHES … - Center for Operations Research and Econometrics (CORE), … - 2009
This paper attempts to give a rationale to public announcements, so often observed in the real world, and to formalize the idea that they can be used as a form of equilibrium selection device when multiple equilibria arise. It also shows how announcements solve the problems of coordination...

Coalitional negotiation
MAULEON, Ana; VANNETELBOSCH, Vincent - Center for Operations Research and Econometrics (CORE), … - 1999
We develop a two-stage negotiation model to study the impact of costly inspections on both the coalition formation outcome and the per-member payoffs. In the first stage, the players are forming coalitions and inside each coalition formed the members share the coalition benefits. We adopt the...

Rationalizability and Equilibrium in N-Person Sequential Bargaining
VANNETELBOSCH, Vincent J. - Center for Operations Research and Econometrics (CORE), … - 1996
This paper deals with N-person sequential bargaining games with complete information (perfect or almost perfect information). For N-person sequential bargaining games, uniqueness of the SPE has been obtained by allowing the players to exit with partial agreements. Adopting a non-equilibrium...

CAMINA, Ester; PORTEIRO, Nicolas - Center for Operations Research and Econometrics (CORE), … - 2004
We develop a model of bargaining that provides a rationality for the difference in the method of negotiation, depending on the nature of the conflict. We distinguish negotiations previous to a potential conflict, and negotiations during a conflict. In these contexts, we study the role of a...

Centralized resource reduction and target setting under DEA control
HOSSEINZADEH LOTFI, Farhad; HATAMI-MARBINI, Adel; … - Center for Operations Research and Econometrics (CORE), … - 2013
Data envelopment analysis (DEA) is a powerful tool for measuring the relative efficiencies of a set of decision making units (DMUs) such as schools and bank branches that transform multiple inputs to multiple outputs. In centralized decision-making systems, management normally imposes common...

A conic optimization approach for SKU rationalization
KEGELART, Tanguy; VAN VYVE, Mathieu - Center for Operations Research and Econometrics (CORE), … - 2014
Expanding variety and the number of offered products is attractive for a firm to fit customer needs. Nevertheless, the greater complexity and the proliferation of stock-keeping units (SKUs) without substantial differentiation may not substantially improve customer satisfaction while raising...
