We study some recent developments and challenges in the empirics of the effects of social networks. We focus in particular on researchers' ability to make policy recommendations based on a standard linear econometric model. We examine the potential compatibility between this type of econometric...

We investigate the relationship among staff engagement, job complementarities and labour supply in the hospital sector, where excessive turnover of the clinical staff (doctors and nurses) can be detrimental for quality of care. We exploit a unique and rich panel dataset constructed by combining...

Retention of skilled workers is essential for labour-intensive organisations like hospitals, where an excessive turnover of doctors and nurses can reduce the quality and quantity of services to patients. In the public sector, where salaries are often not negotiable at individual level, workers...

Does immigration accelerate sectoral change towards high-productivity sectors? This paper uses the mass displacement of ethnic Germans from Eastern Europe to West Germany after World War II as a natural experiment to study this question. A simple two-sector model of the economy, in which moving...

Lottery estimates suggest oversubscribed urban charter schools boost student achievement markedly. But these estimates needn't capture treatment effects for students who haven't applied to charter schools or for students attending charters for which demand is weak. This paper reports estimates...

This paper studies differences in the motivation to be self-employed between rural migrants and urban residents in modern China. Estimates of the wage differential between self-employment and paid-employment obtained through a three-stage methodology using the 2002 China Household Income Project...

The many facets of retirement have been studied widely by economists. However, the effect of retirement on marriage stability has been ignored in the literature. Retirement represents a dramatic change in individual time allocation that may affect marriage stability. In particular, individuals...

In this paper we consider nonparametric estimation of a structural equation model under full additivity constraint. We propose estimators for both the conditional mean and gradient which are consistent, asymptotically normal, oracle efficient and free from the curse of dimensionality. Monte...

This paper estimates the impact of elite school attendance on long-run outcomes including completed education, income and fertility. Our data consists of individuals born in the 1950s and educated in a UK district that assigned students to either elite or non-elite secondary schools. Using...

Earlier studies conclude that spouses' retirement strategies are not independent from each other and that policies affecting individuals in a couple are also likely to affect the economic behaviour of their partner. In this study, we exploit retirement age legislation in France as well as a...
