We investigate the impact of charity tie-ins on transaction probabilities and sale prices using a large database of eBay auctions. We examine "natural experiments" of precisely matched clusters of charity and non-charity auctions with identical titles, subtitles, sellers, and start prices. We...

Quality certification programs help consumers to identify high-quality products or sellers in markets with information asymmetries. Using data from eBay UK's online marketplace, we study how certification's impact on consumer demand varies with market- and seller-level attributes, exploiting...

We study the use of and response to cheap talk by firms and their consumers, focusing on unverifiable promises of charitable donations on eBay. For transactions during March 2005 – May 2006, cheap talk listings have lower sales probabilities but sell at higher prices when they are successful....

We use U.S. eBay data to investigate how trade is influenced by differences in socioeconomic characteristics, tastes, and trust. States' similarity in cultural characteristics (ethnicity, religious affiliations, and political behavior) is predictive of online trade; cultural similarity similarly...

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...

We provide the first empirical analysis of gubernatorial pay. Using US data for 1950-90 we document, contrary to widespread assumptions, substantial variation in the wages of politicians, both across states and over time. Gubernatorial wages respond to changes in state income per capita and...

We study favoritism via hometown ties, a common source of favor exchange in China, in fellow selection of the Chinese Academies of Sciences and Engineering. Hometown ties to fellow selection committee members increase candidates' election probability by 39 percent, coming entirely from the...

We study a 2004 program designed to motivate Chinese bureaucrats to reduce accidental deaths. Each province received a set of ‘death ceilings' that, if exceeded, would impede government officials' promotions. For each category of accidental deaths, we observe a sharp discontinuity in reported...

We study the consequences of month-end lending incentives for Chinese bank managers. Using data from two banks, one state-owned and the other partially privatized, we show a clear increase in lending in the final days of each month, a result of both more loan issuance and higher value per loan....

Politicians and regulators rely on feedback from the public when setting policies. For-profit corporations and non-pro t entities are active in this process and are arguably expected to provide independent viewpoints. Policymakers (and the public at large), however, may be unaware of the...
