“Nudges" - small, usually cheap, interventions to alter the behaviour of individuals to improve their “health, wealth or happiness", are increasingly popular with governments and have thus far played a large role in the coalition government's attempts to encourage pro-social behaviour. The...

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this `crowding out' phenomenon, using standard economic arguments. The...

When and how should a fundraiser ask for a donation from an individual facing an uncertain bonus income? A standard model of expected utility over outcomes predicts that the individual’s before choice – her ex-ante commitment conditional on her income – will be the same as her choice after...

Roughly 20% of adults in the OECD lack basic numeracy and literacy skills. In the UK, many colleges offer fully government subsidized adult education programs to improve these skills. Constructing a unique dataset consisting of weekly attendance records for 1179 students, we find that...

Estimates of intergenerational economic mobility that use point in time measures of income and earnings suffer from lifecycle and attenuation bias. We consider these issues for the National Child Development Study (NCDS) and British Cohort Study (BCS) for the first time, highlighting how common...

Randomised trials in education research are a valuable and increasingly common part of the research landscape. Choosing a sample size large enough to detect an effect but small enough to make the trial workable is a vital component. In the absence of a crystal ball, rules of thumb are often...

It is well-recognised that workers may have intrinsic – as well as extrinsic – motivations. Previous studies have identified that public sector workers typically have a higher level of intrinsic motivation, compared to workers in the private sector. This paper compares (measures of)...

This paper explores the performance of rural governance institutions (Gram Panchayats) in Maharashtra, India. The results of a detailed set of household and village surveys we conducted point to a stunningly robust and participatory democratic process: Elections are freely contested, fairly...

We present new evidence on the effect of grants on charities’ incomes. We employ a novel identification strategy, focusing on charities that applied for lottery grant funding and comparing outcomes for successful and unsuccessful applicants. Overall, grants do not crowd out other income but...

Background: Early childhood diarrheal disease jeopardizes child development by diverting nutrition away from physical and mental growth towards fighting illness. Consequently, early exposure to clean water interventions, which reduce diarrheal risk, may confer positive effects on downstream...
