We study the effects of improvements in market transparency on eBay on seller exit and continuing sellers’ behavior. An improvement in market transparency by reducing strategic bias in buyer ratings led to a significant increase in buyer valuation especially of sellers rated poorly prior to...

We conducted a controlled field experiment on eBay and examined to what extent both social and competitive laboratory behavior is robust to institutionally complex real world markets with experienced traders, who selected themselves into these markets. EBay’s natural trading system provides...

Small farms and fragmented plots are hallmarks of agriculture in less-developed countries, and there is evidence of high returns to land consolidation and reallocation. Complementarities, holdout and asymmetric information mean that private trade will be slow to reallocate land, and imply that...

Crowdfunding provides innovation in enabling entrepreneurs to contract with consumers before investment. Under aggregate demand uncertainty, this improves screening for valuable projects. Entrepreneurial moral hazard and private cost information threatens this benefit. Despite these threats,...

Many economic and political decisions are the outcome of strategic contests for a given prize. The nature of such contests can be determined by a designer who is driven by political considerations with a specific political culture. The main objective of this study is to analyze the effect of...

The literature on public goods has shown that efficient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions efficiency considerations justify that individuals are forced to pay...

This paper characterizes when the one-stage deviation IC constraints in the usual sense of dynamic mechanism design are sufficient. One can easily construct examples of when they are not sufficient. If the current state or the belief is not a sufficient summary statics of the agent's private...

We study a classic mechanism design problem: How to organize trade between two privately informed parties. We characterize an optimal mechanism under selfish preferences and present experimental evidence that, under such a mechanism, a non-negligible fraction of individuals deviates from the...

In many markets, sellers advertise their good with an asking price. This is a price at which the seller will take his good off the market and trade immediately, though it is understood that a buyer can submit an offer below the asking price and that this offer may be accepted if the seller...

In a market in which sellers compete for heterogeneous buyers by posting mechanisms, we analyze how the properties of the meeting technology affect the allocation of buyers to sellers. We show that a separate submarket for each type of buyer is the efficient outcome if and only if meetings are...
