This paper studies sequential auctions of licences to operate in a market where those firms that obtain at least one licence then engage in a symmetric market game. I employ a new refinement of Nash equilibrium, the concept of {\sl Markovian recursively undominated equilibrium}. The unique...

I study monotonicity and uniqueness of the equilibrium strategies in a two-person first price auction with affiliated signals. I show that when the game is symmetric there is a unique Nash equilibrium that satisfies a regularity condition requiring that the equilibrium strategies be {\sl...

This essay reviews some findings in cognition sciences and examines their consequences for the analysis of institutions. It starts by exploring how humans’ specialization in producing knowledge ensures our success in dominating the environment but also changes fast our environment. So fast...

We offer complete characterizations of the equilibrium outcomes of two prominent agenda voting institutions that are widely used in the democratic world: the amendment, also known as the Anglo-American procedure, and the successive, or equivalently the Euro-Latin procedure. Our axiomatic...

Do the contests with the largest prizes attract the most able contestants? To what extent do contestants avoid competition? In this paper, we show, theoretically and empirically, that the distribution of abilities plays a crucial role in determining contest choice. Sorting exists only when the...

Experiments in which subjects play simultaneously several finite prisoner's dilemma supergames with and without an outside option reveal that: (i) subjects use probabilistic start and endeffect behaviour, (ii) the freedom to choose whether to play the prisoner's dilemma game enhances...

Equivalence classes of normal form games are defined using the geometry of correspondences of standard equilibiurm concepts like correlated, Nash, and robust equilibrium or risk dominance and rationalizability. Resulting equivalence classes are fully characterized and compared across different...

We analyze a mutual fire insurance mechanism used in Andorra, which is called La Crema in the local language. This mechanism relies on households' announced property values to determine how much a household is reimbursed in the case of a fire and how payments are apportioned among other...

This paper shows that models where preferences of individuals depend not only on their allocations, but also on the well-being of other persons, can produce both large and testable effects. We study the allocation of workers with heterogeneous productivities to firms. We show that even small...

We study a situation in which an auctioneer wishes to sell an object to one of N risk-neutral bidders with heterogeneous preferences. The auctioneer does not know bidders’ preferences but has private information about the characteristics of the ob ject, and must decide how much information to...
