In service industries with congestion effects, two very different contractual structures are commonly observed, depending on whether or not firms choose to offer a guaranteed service level. We analyze the impact of these choices on market outcomes in oligopolistic industries. Our results...

In this paper we study stochastic dynamic games with many players; these are a fundamental model for a wide range of economic applications. The standard solution concept for such games is Markov perfect equilibrium (MPE), but it is well known that MPE computation becomes intractable as the...

Two very different contractual structures are commonly observed in service industries with congestion effects: service level guarantees (SLGs) and best effort (BE) service. We analyze the impact of these contractual agreements on market outcomes in oligopolistic industries. First, we consider a...
