We study the effects of improvements in eBay's rating mechanism on seller exit and continuing sellers' behavior. Following a large sample of sellers over time, we exploit the fact that the rating mechanism was changed to reduce strategic bias in buyer rating. That improvement did not lead to...

This paper evaluates the effects of the FAMEX export promotion program in Tunisia on the performance of beneficiary firms. While most studies assess only the short-term impact of such programs, we consider also the longer-term impact. Estimates suggest that beneficiaries initially saw both...

We study opaque selling in the hotel industry using data from Hotwire.com. An opaque room discloses only the star level and general location of the hotel at the time of booking. The exact identity of the hotel is disclosed after the booking is completed. Opaque rooms sell at a discount of 40...

Empirical scholarship on the standards-trade relationship has been held up due to methodological challenges: measurement, varied effects, and endogeneity. Considering the trade-effects of one particular standard (ISO 9000), we surmount methodological challenges by measuring standardization via...

This paper investigates whether the Pesticides Initiative Program has significantly affected the export performance of Senegal's horticulture industry. We apply two main microeconometric techniques, difference-in-difference and matching difference-in-differences to identify the effect of the...

Who does, and who should initiate costly certification by a third party under asymmetric quality information, the buyer or the seller? Our answer --- the seller --- follows from a non--trivial analysis revealing a clear intuition. Buyer--induced certification acts as an inspection device, whence...

Empirical models of differentiated product demand are widely used by both academics and practitioners. While these methods treat carefully the potential endogeneity of price, until recently they have assumed the number and characteristics of the products offered by firms are exogenous. This...

Technological change is transforming creative media industries. Digitisation lowers recording, storage, reproduction and distribution costs, while computer-based editing facilitates higher quality and special effects. With electronic distribution a vast range of content can be made available to...

In markets with imperfect information and heterogeneity, the information technology affects the rate at which agents meet, which in turn affects the distribution of production technologies across firms. We show that in models for such markets there are typically multiple equilibria because...

In recent years various contributions have analyzed the credence goods problem under a wide variety of assumptions yielding equilibria exhibiting various degrees of inefficiencies and fraud. The variety of results has fostered the impression that the equilibrium behaviour of experts and...
