We show that children who are born at the weekend or just before are less likely to be breastfed, owing to poorer breastfeeding support services at weekends. We use this variation to estimate the effect of breastfeeding on children's development for a sample of uncomplicated births from low...

In this paper, we estimate a collective model of household consumption and test the restrictions of collective rationality using z-conditional demands in the context of a large Conditional Cash Transfer programme in rural Mexico. We show that the model is able to explain the impacts the...

We develop an equilibrium model of on-the-job search with ex-ante heterogeneous workers and firms, aggregate uncertainty and vacancy creation. The model produces rich dynamics in which the distributions of unemployed workers, vacancies and worker-firm matches evolve stochastically over time. We...

The standard expected utility model of tax evasion predicts that evasion is decreasing in the marginal tax rate (the Yitzhaki Puzzle). The existing literature disagrees on whether prospect theory overturns the puzzle. We disentangle four distinct elements of prospect theory and find loss...

This paper analyses the career progression of skilled and unskilled workers with a focus on how careers are affected by economic downturns and whether formal skills, acquired early on, can shield workers from the effect of recessions. Using detailed administrative data for Germany for numerous...

This paper presents evidence from Rwanda's Girinka ('One Cow per Poor Family') program that has distributed more than 130,000 livestock asset transfers in the form of cows to the rural poor since 2006. Supply side constraints on the programe results in some beneficiaries receiving complementary...

The UK government is in the process of introducing a radical package of welfare reforms that it hopes will encourage more people to work as well as reducing government expenditure. The largest structural change planned is the introduction of universal credit to combine six existing means-tested...

This working paper describes how the IFS's model of the UK's long-run public finances (and those of its constituent nations) is constructed. Our model projects tax revenues, public spending and hence public borrowing and debt up to 2062-63. This is done for the UK as a whole and also separately...

This paper presents a nonparametric analysis of a common class of intertemporal models of consumer choice that relax consumption independence. Within this class and in the absence of any functional form restrictions on instantaneous preferences, we compare the revealed preference conditions for...

We investigate the role of complementarities in production and skill mobility across cities. We propose a general equilibrium model of location choice by heterogeneously skilled workers, and consider different degrees of complementarities between the skills of workers. The nature of the...
