Revealed preference restrictions are increasingly used to bound demand responses and as shape restrictions in nonparametric estimation exercises. However, the restrictions imposed are not sufficient for rationality when predictions are made at more than a single price regime. We highlight the...

This paper provides a novel portrait of firms engaging in the international use of inventors. I focus on drug discovery activity of pharmaceutical and biotechnological firms head-quartered in Europe, over the period 1996-2005. An important part of the most high-valued added R&D activities are...

Health spending per capita in England has more than doubled since 1997, yet relatively little is known about how that spending is distributed across the population. This paper uses administrative National Health Service (NHS) hospital records to examine key features of public hospital spending...

We develop a tax micro-simulator model (MEXTAX) that can quantify the revenue and distributional impact of tax reforms in Mexico using micro-level data. We use MEXTAX to assess revenue-raising reforms to Mexico's direct and indirect tax systems of 2010. Initial proposals by the Executive Power...

This paper investigates how changes in hospital choice sets affect levels of patient demand for elective hospital care. We exploit a set of reforms in England that opened up the market for publicly-funded patients to private hospitals. Impacts on demand are estimated using variation in distance...

We develop a new quantile-based panel data framework to study the nature of income persistence and the transmission of income shocks to consumption. Log-earnings are the sum of a general Markovian persistent component and a transitory innovation. The persistence of past shocks to earnings is...

Consider a finite data set where each observation consists of a bundle of contingent consumption chosen by an agent from a constraint set of such bundles. We develop a general procedure for testing the consistency of this data set with a broad class of models of choice under risk and under...

The labor market by itself can create cyclical outcomes, even in the absence of exogenous shocks. We propose a theory that shows that the search behavior of the employed has profound aggregate implications for the unemployed. There is a strategic complementarity between active on-the-job search...

Most analysis of the effects of the tax and benefit system is based on snapshot information about a single cross-section of people. Such an approach gives only a partial picture because it cannot account for the fact that circumstances change over life. This paper investigates how our impression...

Over the Great Recession UK households reduced real food expenditure. We show that they were able to maintain the number of calories that they purchased, and the nutritional quality of these calories, by adjusting their shopping behaviour. We document the mechanisms that households used. We...
