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....

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 the assigned treatments in his market. To evaluate how the...

Econometric evaluations of public-sponsored training programmes generally find little evidence of an impact of such policies on transition rates out of unemployment. We perform the first evaluation of training effects for the unemployed adults in France, exploiting a unique longitudinal dataset...

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...

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...

The control function in the semiparametric selection model is zero at infinity. This paper proposes additional restrictions of the same type and shows how to use them to test assumed exclusion restrictions necessary for root N estimation of the model. The test is based on the estimated control...

We use longitudinal individual wage, hours, and employment data to investigate the effect of the February 1, 1982 mandatory reduction of weekly working hours in France. Just after François Mitterrand’s election in May 1981, the government decided to increase the minimum wage by 5%. Then, as...

The randomized trial literature has helped to renew the fields of microeconometric policy evaluation by emphasizing identification issues raised by endogenous program participation. Measurement and attrition issues have perhaps received less attention. This paper analyzes the dramatic impact of...

French firms laying off workers aged 50 and above have to pay a tax to the unemployment insurance system, known as the Delalande tax. This is an original case of experience rating in the European context, restricted to older workers, whose employment prospects are particularly bad. We evaluate...
