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 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...

We extend the standard evaluation framework to allow for interactions between individuals within segmented markets. An individual's outcome depends not only on the assigned treatment status but also on (features of) the distribution of treatments in his market. To evaluate how the distribution...

When treatments may occur at different points in time, most evaluation methods assume - implicitly or explicitly - that all the information used by subjects about the occurrence of a future treatment is available to the researcher. This is often called the no anticipation assumption. In reality,...

We conduct a joint dynamic analysis of individual labor market and mental health outcomes. We allow for a two-way interaction between work and mental health. We model selection in and out of employment as well as between jobs on a labor market with search frictions, where we account for the...

We show that equilibrium matching models imply that standard estimates of the matching function elasticities are exposed to an endogeneity bias, which arises from the search behavior of agents on either side of the market. We offer an estimation method which, under certain assumptions, is immune...

This chapter surveys recent literature on the drivers of mothers’ labour supply in OECD countries. We present a number of facts on the variations across time and across countries of family composition and mothers’ employment. We aim to answer key questions on their decision to return to work...

We propose a model to evaluate the U.K.'s zero-hours contract (ZHC) - a contract that exempts employers from the requirement to provide any minimum working hours, and allows workers to decline any workload. We find quantitatively mixed welfare effects of ZHCs. On one hand they unlock job...
