We analyze the problem faced by a financially weak independent inventor when selling a valuable, but easily imitated, invention for which no property rights exist. The inventor can protect his or her intellectual property by negotiating a contingent contract (with a buyer) prior to revealing the invention or, alternatively, the inventor can reveal the invention and then negotiate with the newly informed buyer. Despite the risk of expropriation, we find that, in equilibrium, an inventor with little wealth can expect to appropriate a sizable share of the market value of the invention by adopting the latter approach.

Ideas are difficult to sell when buyers cannot assess an idea's value before it is revealed and sellers cannot protect a revealed idea. These problems exist in a variety of intellectual property sales ranging from pure ideas to poorly protected inventions and reflect the nonverifiability of key elements of an intellectual property sale. An expropriable partial disclosure can be used as a signal, allowing the seller to obtain payment based on the value of the remaining (undisclosed) know-how. We examine contracting after the disclosure and find that seller wealth is pivotal in supporting a partial disclosure equilibrium and in determining the payoff size.

We analyze split award procurement auctions in which a buyer divides full production between two suppliers or awards all production to a single supplier, and suppliers have private cost information. An intriguing feature of split awards is that the equilibrium bids are implicitly coordinated. Because a split award price is the sum of offered split prices, each supplier can unilaterally veto a split award by bidding very high for the split. The need to coordinate is reflected in a split price that does not vary with private information. We also explore conditions under which split award auctions may be preferred to winner-take-all auctions.
