Imitation of Cooperation in Prisoner's Dilemma Games with Some Local Interaction

Janssen, Maarten C.W. - 2000

In this paper I study conditions for the emergence of cooperativebehavior in a dynamic model of population interaction.The model has finitely many individuals located on a circle. The pay-off of each individual is partly based on the (local)interaction with neighbors and partly on (uniform)...

In and Out of Equilibrium: Evolution of Strategies in Repeated Games with Discounting

van Veelen, Matthijs; Garcia, Julian - 2010

Repeated games tend to have large sets of equilibria. We also know that in the repeated prisoners dilemma there is a profusion of neutrally stable strategies, but no strategy that is evolutionarily stable. This paper shows that for all of these neutrally stable strategies there is a stepping...

In and out of Equilibrium II: Evolution in Repeated Games with Discounting and Complexity Costs

van Veelen, Matthijs; Garcia, Julian - 2012

We explore evolutionary dynamics for repeated games with small, but positive complexity costs. To understand the dynamics, we extend a folk theorem result by Cooper (1996) to continuation probabilities, or discount rates, smaller than 1. While this result delineates which payoffs can be...

Repeated prisoner's dilemmas with errors: How much subgameperfection, how much forgiveness, and how much cooperation?

Graser, Christopher; van Veelen, Matthijs - 2024

We consider the repeated prisoner's dilemma with implementation errors, and look at the resulting population dynamics, both analytically and with simulations. We show that with implementation errors, pure equilibrium strategies represented by finite state automata exhibit a structure that we...

Free Medicines thanks to Retirement: Moral Hazard and Hospitalization Offsets in an NHS

Puig-Junoy, Jaume; Garcia-Gomez, Pilar; Casado-Marin, David - 2011

This paper examines the impact of coinsurance exemption for prescription medicines applied to elderly individuals in Spain after retirement. To evaluate this coinsurance change we use a rich administrative dataset that links pharmaceutical consumption and hospital discharge records for the full...

Bargaining power and quantity discounts to retailers: Evidence from India's pharmaceutical industry

Antonecchia, Gianluca; Bhaskarabhatla, Ajay; Pennings, … - 2024

This paper develops a novel theory linking quantity discounts to bargaining power in scenarios where retailers …, organized as a trade association, negotiate uniform wholesale prices with suppliers. Our theory predicts that suppliers offer … observed. Our findings provide empirical support for the proposed theory. …

SETS, Arbitrage Activity, and Stock Price Dynamics

Taylor, Nick; van Dijk, Dick; Franses, Philip Hans; … - 1999

This paper provides an empirical description of the relationshipbetween the trading system operated by a stockexchange and the transaction costs faced by heterogeneous investors who use the exchange. Therecent introduction ofSETS in the London Stock Exchange provides an excellent opportunity...

A Comparison of Minimum MSE and Maximum Power for the nearly Integrated Non-Gaussian Model

Abadir, Karim M.; Lucas, Andre - 2000

We study the optimal choice of quasi-likelihoods for nearly integrated,possibly non-normal, autoregressive models. It turns out that the two mostnatural candidate criteria, minimum Mean Squared Error (MSE) and maximumpower against the unit root null, give rise to different...
