We report results of a series of experiments designed to test the stability of the best reply process. With linear demand and cost functions, the process is stable if and only if there are less than three firms in the market. However, we find no experimental evidence of such instability in a...

Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...

We introduce a generalized theoretical approach to study imitation models and subject the models to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different...

This paper investigates the impact of information about rivals' actions on the competitiveness of experimental oligopoly markets. We compare two treatments: in one, firms are informed about their rivals' actions and profits. In the other, firms are only given some aggregate information about...

In this note we study a very simple trial & error learning process in the context of a Cournot oligopoly. Without any knowledge of the payoff functions players increase, respectively decrease, their quantity by one unit as long as this leads to higher profits. We show that this process converges...

In a repeated game with private information, a perfect public equilibrium (PPE) can break down if communication is not necessarily simultaneous or if players can “spy” on each others’ information. An ex post perfect public equilibrium (EPPPE) is a PPE that is ex post incentive compatible...

We use an experiment to explore how subjects learn to play against computers which are programmed to follow one of a number of standard learning algorithms. The learning theories are (unbeknown to subjects) a best response process, fictitious play, imitation, reinforcement learning, and a trial...

En este artículo se presenta una descripción de la industria de televisión en Colombia haciendo distinción entre el servicio de televisión cerrada (o por suscripción) y el de televisión abierta. En el caso de este último, se propone un modelo coalicional para hacer una aproximación a la...

The paper shows that there is a close connection between (constant) consistent conjectures in a given game and evolutionary stability of conjectures. Evolutionarily stable conjectures are consistent and consistent conjectures are the only interior candidates for evolutionary stability.
