This paper develops a methodology for characterizing expected revenue from auctions when bidders' types come from an arbitrary distribution. In particular, types may be multidimensional, and there may be mass points in the distribution. One application extends existing revenue equivalence...

We study the assignment of initial ownership of a good when agents differ in their ability to pay. Selling the good at the market-clearing price favors the wealthy in the sense that they may acquire the good instead of poor buyers who value it more highly. Non-market assignment schemes, even...

We study the initial assignment of ownership of a good. When the good is sold at the market-clearing price, wealthy agents may acquire it instead of poor agents who value it more highly, all else equal. Non-market assignment schemes such as random rationing may allocate the good more efficiently...

Many new products (e.g., weapons systems) require substantial innovative effort by suppliers. Procurement of effort through bilateral contracting is often problematic, however, because the effort may be unverifiable and cooperative. That is, a third party cannot verify the level of effort, and...
