We compare first-price auctions to an exchange process that we term ``multilateral negotiations.'' In multilateral negotiations, a buyer solicits price offers for a homogeneous product from sellers with privately known costs, and then plays the sellers off one another to obtain additional price...

When the value of a product or service is uncertain, outcomes can be inefficient. A market for evaluations can theoretically increase efficiency by voluntarily eliciting an evaluation that would otherwise not be provided. This paper uses a controlled laboratory experiment to test the performance...

The electronic technologies of the Internet make it possible for sellers to track potential customers and discriminate between the informed and uninformed. In this article, we report an experiment that investigates the market impact of firms tracking customers and offering discriminatory prices...

This paper uses a laboratory experiment to probe the proposition that property emerges anarchically out of social custom. We test the hypothesis that whalers in the 18th and 19th century developed rules of conduct that minimized the sum of the transaction and production costs of capturing their...

We experimentally compare first-price auctions and multilateral negotiations after introducing horizontal product differentiation into a standard procurement setting. The two institutions yield the buyer the same surplus, a difference from prior findings with homogeneous products that results...

Research shows that many animal species have morphological and cognitive adaptations for fighting with others to gain resources, but it remains unclear how humans make fighting decisions. Non-human animals often adaptively calibrate fighting behavior to ecological variables such as resource...
