We examine the structure of more than 100 alliances by Internet portals and other firms between 1995 to 1999 from a contract-theory perspective. Models of incomplete contracts frequently invoke unforeseen contingencies, the cost of writing contracts, and the cost of enforcing contracts in...

This paper examines the structure of over 100 alliances by Internet portals from 1995 to 1999. These alliances were an attractive empirical testing ground because of the large number and heterogeneous nature of the contracts, the high standards for disclosure in the industry, and the careful...

Scientists and engineers in small firms are far more likely than their large firm counterparts to enter entrepreneurship. We label this phenomenon the small firm effect and explore its origins. In particular, we identify four classes of explanations for the small firm effect--preference sorting,...

Relative to typical eBay auctions, bidding in eBay charity auctions occurs earlier and also less frequently in the auctions' final seconds. This suggests that some charity bidders benefit from driving-up others' payments, as when auction revenue is a public good.

To study whether consumers will pay more for products that generate charitable donations, we analyze data from eBay on charity and noncharity auctions of otherwise identical products. Charity prices are 6 percent higher, on average, than noncharity prices. Bids below the closing price are also...

Consumers respond positively to products tied to charity, particularly from sellers that are relatively new and hence have limited alternative means of assuring quality. We establish this result using data from a diverse group of eBay sellers who "experiment" with charity by varying the presence...

We explore the relationship between exclusivity and state-contingent control rights using a sample of over 100 Internet portal alliance contracts. We find that stronger exclusivity arrangements are associated with more frequent usage of contingent control rights. For both portals and their...
