This paper considers a class of combinatorial auctions with ascending prices, which includes the Vickrey-Clarke-Groves mechanism and core-selecting auctions. In every ascending auction, the Vickrey-target strategy, i.e., bidding up to the Vickrey price based on provisional valuations,...

We introduce a general class of simplicity standards that vary the foresight abilities required of agents in extensive-form games. Rather than planning for the entire future of a game, agents are presumed to be able to plan only for those histories they view as simple from their current...

In Hawk-Dove games with mulitiplicity of equilibria, we study which equilibria are selected using various equilibrium selection methods. Using a uniform price auction as an illustrative example, we apply the tracing procedure method of Harsanyi and Selten (1988), the robustness to strategic...

In many markets, sellers advertise their good with an asking price. This is a price at which the seller is willing to take his good off the market and trade immediately, though it is understood that a buyer can submit an offer below the asking price and that this offer may be accepted if the...

When selling goods like wireless spectrum or electricity contracts, auction designers often opt for core-selecting mechanisms -- i.e., auctions that induce outcomes in the core -- in order to balance revenue and efficiency goals. But increasingly, auctions -- such as the FCC's 2016-17 Incentive...

Investors' Exchange LLC (IEX) is a newly approved public exchange that is designed to discourage aggressive high-frequency trading. We explain how IEX differs from traditional continuous double auction markets and present summary data on IEX transactions by trader class and or- der type. Our...

This paper identifies a condition for an efficient social choice rule to be fully implementable when we take into account investment efficiency. To do so, we extend the standard implementation problem to include endogenous ex ante and ex post investments. In our problem, the social planner aims...

Many sales, sports, and research contests are put in place to maximize contestants’ performance. We investigate and provide a complete characterization of the prize structures that achieve this objective in settings with many contestants. The contestants may be ex-ante asymmetric in their...
