In this paper, we develop a revealed preference methodology that allows us to explore whether time inconsistencies in household choice are the product of individual preference nonstationarities or the result of individual heterogeneity and renegotiation within the collective unit. An empirical...

One of the most powerful critiques of the use of randomised experiments in the social sciences is the possibility that individuals might react to the randomisation itself, thereby rendering the causal inference from the experiment irrelevant for policy purposes. In this paper we set out a...

Sharp nonparametric bounds are derived for Hicksian compensating and equivalent variations. These 'i-bounds' generalize earlier results of Blundell, Browning and Crawford (2008). We show that their e-bounds are sharp under the Weak Axiom of Revealed Preference (WARP). They do not require...

We use an RCT to analyse the impact of microcredit on poverty reduction in Bosnia. The study population are loan applicants that would normally have just been rejected based on regular screening. We find that access to credit allowed borrowers to start and expand small-scale businesses....

It is often argued that informal labor markets in developing countries promote growth by reducing the impact of regulation. On the other hand informality may reduce the amount of social protection offered to workers. We extend the wage-posting framework of Burdett and Mortensen (1998) to allow...

A model of labour supply is developed in which individuals face restrictions on hours choices. Observed hours reflect both the distribution of preferences and the distribution of offers. In this framework the choice set is limited and observed hours may not appear to satisfy the revealed...

This paper provides causal estimates of the effect of teacher pay on pupil attainment using a sharp geographical discontinuity in teacher salaries. We compare schools in close proximity to a pay zone boundary to estimate the effect of teacher salary differentials on pupil attainment. We find...

In October 2012, the ONS announced a consultation on whether the statistical methods used to calculate the Retail Prices Index (RPI) should be changed to bring them closer in line to those used in the Consumer Prices Index (CPI). Previous IFS work has looked at how inflation rates varied across...

Prices of real and financial assets fell substantially in the UK during 2008–09. The fourth wave of the English Longitudinal Study of Ageing (ELSA) was in the field throughout this ‘financial crisis’. We use these data and earlier ELSA waves first to document the effect of...

Much empirical research in economics is based on data from household surveys. Panel surveys are particularly valuable for understanding dynamics and heterogeneity. A possible concern with panel surveys is that survey participation itself may alter subsequent behavior. We provide novel evidence...
