Car owners are liable for property damage inflicted on other motorists. In most countries such liability must be insured by law. That law may favor expensive or heavy vehicles, prone to suffer or inflict large losses. This paper explores links between liability rules and vehicle choice. It...

Due to their many applications, large Bayesian games have been a subject of growing interest in game theory and related fields. But to a large extent, models (1) have been restricted to one-shot interaction, (2) are based on an assumption that player types are independent and (3) assume that the...

We study from an algorithmic viewpoint anonymous games[22,4,5,19]. In these games a large population of players shares the same strategy set and, while players may have different payoff functions, the payoff of each depends on her own choice of strategy and the number of the other players...

We consider small-influence anonymous games with a large number of players n where every player has two actions. For this class of games we present a best-reply dynamic with the following two properties. First, the dynamic reaches Nash approximate equilibria fast (in at most cnlogn steps for...

This paper shows that more intense competition may improve, rather than hamper, the chances that a market for an experience good or service overcomes the problems caused by informational asymmetries. This, in spite of the fact that intensified competition diminishes the reputational rents that...

This short survey discusses recent findings on the robustness of Nash equilibria of strategic games with many semianonymous players. It describes the notion of structural robustness and its general consequences, as well as implications to particular games, such as ones played on the web and...
