Mixed proportional hazard models are commonly used to estimate duration dependence and unobserved heterogeneity in unemployment exit rates. Some strong assumptions are made in this framework, i.e. that the various influences on the individual unemployment exit rate are separable. The model we...

Geographic school admissions criteria bind residential and school choices for some parents, and could create externalities in equilibrium for non-parents through displacement or higher rent. Through a dynamic structural model, we show that the policy decision of geographic versus non-geographic...

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 employees to decline any workload. We find quantitatively that ZHCs improve welfare by enabling firms with more volatile...

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...

We formalize and estimate the dynamic marginal efficiency cost of redistribution (MECR) in the spirit of Okun's "leaky bucket". We analyze the MECR of an income-contingent childcare subsidy program and the income tax within the German context, using a dynamic structural heterogeneous-household...

It is well known that German and Spanish labour markets are quite different from a macro point of view. In this paper, we look at these markets through the lenses of individual unstable spells. These include all forms of atypical employment (such as temporary contracts and mini-jobs) as well as...

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 proposes a dynamic structural model of labour market and childcare choices for couples within a collective model of decision making. We formalise explicitly the need for childcare as a function of the age structure of the children population in the household then examine the...
