This paper studies the possibility of implementing Pareto optimal outcomes in the combinatorial auction setting where bidders may have budget constraints. I show that when the setting involves a single good, or multiple goods but with single-minded bidders, there is a unique mechanism, called...

This paper studies the possibility of implementing Pareto optimal outcomes in the combinatorial auction setting where bidders may have budget constraints. I show that when bidders are single-minded, there is a unique mechanism, called truncation VCG, that is individually rational, incentive...

This paper studies the welfare consequence of increasing trading speed in financial markets. We build and solve a dynamic trading model, in which traders receive private information of asset value over time and trade strategically with demand schedules in a sequence of double auctions. A...

This paper extends the Fishman (1988) model of preemptive jump bidding in private value takeover auction to auctions with common and affiliated values. We show that in the presence of a common value component, jump bidding equilibrium results in higher social surplus. Furthermore, we show that,...
