Abstract

The main purpose of this paper is to study the economics of interchange fee in payment card association. The different arrangements for interchange fees and the nosurcharge rule lower the level of competition intensity that would otherwise have occurred and push interchange fees up. In many countries, competition regulators carried out investigations on the lack of transparency and competition in these card-based payment systems, and took measurements for an optimal determination of interchange fees. To help understand and predict the evolution of payment markets, we use an agent-based model that simulates strategic behaviours for different levels of interchange fee. We thus observe the social welfare and the intensity of competition on both the buyer and seller sides of intermediate markets.
