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. …

Competition and the Evolution of Market Structure in the E-conomy : A Simulation Analysis
Friedrich, B. Cornelia - 2004
In this paper an evolutionary simulation model, based on replicator dynamics, is developed. The purpose is to identify changes in the patterns of evolution of the market structure caused by Information and Communication Technologies (ICT) in the E-conomy in comparison to the Old Economy (without...

The Value of Non-Binding Announcements in Public Goods Experiments: some Theory and Experimental Evidence
Markwardt, Gunther; Dittrich, Marcus; Berlemann, Michael - 2004
In this paper we present three simple theoretical models to explain the influence of the possibility to make non-binding announcements on future investment behaviour in public good settings. Our models build on the idea that voluntary contributions to the supply of a public good might be...
