This paper studies the effects of increasing the number of sellers on Quantal Response Equilibrium (QRE) prices in homogeneous product Bertrand oligopoly markets. We show that the two most commonly used choice functions (power and logistic) lead to qualitatively different comparative-static predictions with respect to the relationship between number of firms and prices.

This paper presents an experiment that evaluates the effect of financial incentives and complexity in political science voting experiments. To evaluate the effect of complexity we adopt a level-k reasoning model concept. This model by Nagel [1] postulates that players might be of different types, each corresponding to the level of reasoning in which they engage. Furthermore, to postulate the ef...

This paper investigates the implications of normaland extensive-form quantal response equilibrium (QRE) models (McKelvey and Palfrey, 1995, Games and Economic Behavior; 1998, Experimental Economics) in the ultimatum bargaining game, assuming that players maximize expected monetary payo ̄ s. It is shown that normal-form QRE can select a non-sequential equilibrium, and that the selection depends c...

The notable increase in petroleum demand, together with a decline discovery rates, has highlighted the desire for efficient production of existing oil wells worldwide. Mainly, productivity large fields makes us consider principles managing reservoirs to make most extraction. At same time, many different uncertainties course developing field, including geological, operational, and economic uncer...
