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 packa...
The high-frequency trading arms race is a symptom of flawed market design. Instead of the continuous limit order book market design that is currently predominant, we argue that financial...
Auctions that select core allocations with respect to reported values generate competitive levels of sales revenues at equilibrium and limit bidder incentives to use shills. Among core-selecting aucti...
A mechanism can be simplified by restricting its message space. If the restricted message spaces satisfy a certain “outcome closure property,” then the simplification istight”: for every ε  0, any ...
This paper identifies two notions of substitutes for auction and equilibrium analysis. Weak substitutes,the usual price-theory notion, guarantees monotonicity of tatonnement processes and convergence ...
Auctions that select core allocations with respect to reported values generate competitive levels of sales revenues at equilibrium and limit bidder incentives to use shills. Among core-selecting aucti...
We report recent advances concerning the package allocation problem, in which traders seek to buy or sell combinations of goods. The problems are most difficult when some goods are not substitutes. In...

Theoretical treatments of auctions usually analyze situations in which there is some particular item to be bought or sold and the question is what auction format to use. In real auctions, however, the...
The Vickrey and ascending package auctions are found to have identical equilibrium performance in the case where goods are substitutes. In the remaining cases, the Vickrey auction retains its incentiv...
A family of ascending package auction models is introduced in which bidders may determine their own packages on which to bid. In the proxy auction (revelation game) versions, the outcome is a point in...

This paper was written in early 1982. On the basis of results from previous research, we had informally conjectured that sequential auctions of the types treated here would yield upward-drifting price...

Auctions and Bidding: A Primer.
Consumer auctions were very popular in the early days of internet commerce, but today online sellers mostly use posted prices. Data from eBay shows that compositional shifts in the items being sold,...
