We introduce the game in cover function form, which is a bargaining game of sequential offers for endogenous overlapping coalitions. This extension of games in partition function form removes the restriction to disjoint coalitions. We discuss the existence of equilibria, and we develop an...

This article is an experimental investigation on decision making in online auction markets. We focus on a widely used format, the Buy-It-Now auction on eBay, where sellers post prices at which buyers can purchase a good prior to an auction. Even though, buyer behavior is well studied in...

We study the policy choice of an incumbent politician who is concerned with the public's perception of his capability. The politician decides whether to maintain the status quo or to conduct a risky reform. The success of the reform critically depends on the ability of the politician in oce,...

This paper analyzes the trade of an indivisible good within a two-stage mechanism, where a seller first negotiates with one potential buyer about the price of the good. If the negotiation fails to produce a sale, a second-price sealed-bid auction with an additional buyer is conducted. The...

Controlled choice over public schools attempts giving options to parents while maintaining diversity, often enforced by setting feasibility constraints with hard upper and lower bounds for each student type. We demonstrate that there might not exist assignments that satisfy standard fairness and...

We study a general class of priority-based allocation problems with weak priority orders and identify conditions under which there exists a strategy-proof mechanism which always chooses an agent-optimal stable, or constrained efficient, matching. A priority structure for which these two...

We consider competitive and budget-balanced allocation rules for problems where a number of indivisible objects and a fixed amount of money is allocated among a group of agents. In “small” economies, we identify under classical preferences each agent's maximal gain from manipulation. Using...
