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...

Information decay in networks generates two effects. First, it differentiates how well informed different players within the same component are, and therefore how attractive they are to sponsor links to. Second, players may prefer to sponsor links to players they are already connected to. By...

This is the first study investigating the development of the capability to reason backwards in children, adolescents, and young adults aged 6 to 23 under controlled laboratory conditions. The experimental design employs a modified version of the race game. As in the original game, subjects need...

In the basic adverse selection model, a seller makes a contract offer to a privately informed buyer. A fundamental hypothesis of incentive theory is that the seller may want to offer a menu of contracts to separate the buyer types. In the good state of nature, total surplus is not different from...

What is common to the following situations: designing random incentive schemes to implement team effort, monopoly pricing when consumers are loss averse, arms races when players are privately informed of their armament costs? We present a simple formalism, called X-games, which captures these...

We know that a) two-player symmetric zero-sum games with non-empty equilibrium sets always admit symmetric equilibria and that b) two-player and multiplayer symmetric non-zero-sum games might have only asymmetric equilibria (Fey, 2012). But what about multiplayer symmetric zero-sum games? This...

We study multi-object auctions in the presence of post-auction trade opportunities among bidders who have either single- or multi-object demand. We focus on two formats: Vickrey auctions where package bidding is possible and simultaneous second-price auctions. We show that, under...

This paper reexamines the work of Kempf and Rota-Graziosi (J. Pub. Econ. 94: 768-776, 2010), which shows that leadership by the small region is the risk dominant equilibrium under the endogenous timing game. They obtained this result in a model where the asymmetry among regions translates into...

The question how to optimally design an infrastructure network that may be subject to intelligent threats is of highest interest. We address this problem by considering a Designer-Adversary game of optimal network design for the case of imperfect node defense. In this two-stage game, first the...

The corporate leniency program has played an important role in detecting cartels that damages consumer welfare and competition. This study investigates the impacts of Korea¡¯s leniency revision in 2005 on cartel stability by using a Poisson regression. The estimation results show that the new...
