We analyse consumers' search and purchase decisions on an Internet platform. Using a rich dataset on all adverts posted and transactions made on a major French Internet platform (PriceMinister), we show evidence of substantial price dispersion among adverts for the same product. We also show...

This paper provides a method to infer the presence of treatment spillovers within markets where a fraction of agents is treated. We model individual outcomes as functions of the assigned treatment status and the distribution of assigned treatments in a market. We develop a two-step...

Abstract Job characteristics can affect worker turnover through their effect on utility and through their effect on outside job opportunities. We separately identify and estimate the roles of these two channels. Our method exploits information on job changes and relies on an augmented sample...

The broad aim of this paper is to gain some insight into the quantitative importance of reputation in e-commerce. We use an exhaustive data set from one of France’s largest e-commerce platforms, <a href="http://www.priceminister.com/">PriceMinister.com </a>, to estimate a statistical causal effect of a seller’s reputation (and size)...

This paper implements a method to identify and estimate treatment effects in a dynamic setting where treatments may occur at any point in time. By relating the standard matching approach to the timing-of-events approach, it demonstrates that effects of the treatment on the treated at a given...

Job search models of the labor market establish a very tight correspondance between the determinants of labor turnover and individual wage dynamics on one hand, and the determinants of wage dispersion on the other. This paper offers a systematic examination of wether this correspondance is...

We write and estimate a dynamic model of wages, amenities and labor mobility.Workers trade off wage and amenity offers when deciding whether to change jobs,while facing heterogenous mobility costs. We show that these frictions can turn strongindividual preferences for non wage characteristics...
