Financial markets are increasingly concerned about financial risks resulting from companies' environmental exposures and are demanding greater disclosure and transparency. Despite longstanding securities laws and regulations requiring such disclosures where environmental information is material,...

We introduce a subsidized Vickrey auction for cost sharing problems. Although the average, marginal, and serial cost sharing mechanisms are budget-balanced, they are not allocatively efficient and they do not induce players to truthfully reveal their values as a dominant strategy. The...

The Federal Communications Commission (FCC) spectrum auctions use a simultaneous ascending auction design. Bidders bid on numerous communication licenses simultaneously, with bidding remaining open on all licenses until no bidder is willing to bid higher on any license. With full revelation of...

This paper describes the signaling that occurred in many of the FCC spectrum auctions. The FCC's simultaneous ascending auctions allowed bidders to bid on numerous communication licenses simultaneously, with bidding remaining open on all licenses until no bidder was willing to raise the bid on...

A necessary and sufficient condition for dominant strategy implementability when preferences are quasilinear is that, for any individual i and any choice of the types of the other individuals, all k-cycles in i's allocation graph have nonnegative length for every integer k � 2. Saks and Yu...

This paper describes the signaling that occurred in many of the FCC spectrum auctions. The FCC's simultaneous ascending auctions allowed bidders to bid on numerous communication licenses simultaneously, with bidding remaining open on all licenses until no bidder was willing to raise the bid on...

This paper examines the conventional wisdom, expressed in McAfee and McMillan's (1987) widely cited survey paper on auctions, that links increased variance of bidder values to increased information rent. We find that although the conventional wisdom does indeed hold in their (1986) model of a...

We study online markets, where two sellers sequentially choose reserve prices and then hold ascending auctions. Buyers can bid in both auctions and can switch between them as frequently as they like. We adapt the revenue equivalence approach of Myerson (1981) to obtain total revenue generated by...

The risks of extreme weather events are typically being estimated, by federal agencies and others, with historical frequency data assumed to reflect future probabilities. These estimates may not yet have adequately factored in the effects of past and future climate change, despite strong...
