Employee referrals are a very common means by which firms hire new workers. Past work suggests that workers hired via referrals often perform better than non-referred workers, but we have little understanding as to why. In this paper, we demonstrate that this is primarily because referrals allow...

This paper presents the results of a randomized experiment analyzing the use of vouchers for adult training. In 2006, 2,400 people were issued with a training voucher which they were entitled to use in payment for a training course of their choice. User behavior was compared with a control group...

The number of university students participating in exchange programs has risen sharply over the last decade, but a survey of Swiss university graduates (class of 1999 and 2001) shows that participation in student exchange programs significantly prolongs the period of time spent studying at...

A review of the basic theory of optimal open-source software contributions points to three key factors affecting supply: non-pecuniary benefits, future expected monetary returns, and opensource licence type. This paper argues that existing large-scale software developer surveys are inadequate...

Does Protestantism favour the market economy more than Catholicism does? We provide a novel quasi-experimental way to answer this question by comparing Protestant and Catholic minorities using Swiss census data from 1970 to 2000. Exploiting the strong adhesion of religious minorities to their...

Lifelong learning is often promoted in ageing societies, but little is known about its returns or governments' ability to advance it. This paper evaluates the effects of a large-scale randomized field experiment issuing vouchers for adult education in Switzerland. We find no significant average...

The purpose of this paper is two-fold. We firstly produce a labour market profile of non-Irish immigrants who arrived in Ireland in the ten years to 2003. We then go on to use the labour market profile in estimating the impact of immigration (non-Irish) on the Irish labour market. Immigrants are...

Much has been written about the labour market outcomes for immigrants in their host countries, particularly with regard to earnings, employment and occupational attainment. However, much less attention has been paid to the question of whether immigrants are as likely to receive employer-provided...

The current research emphasis on institutions as key determinants of economic performance, rather than on resources and resource productivity, has uncovered important questions for further research. For example, if institutions are central to economic performance, then what explains observed...

Institutions either promote or constrain economic performance, but which parts of institutions advance or restrict performance, and why do economies sharing similar institutions sometimes perform differently? This paper is a modest attempt at addressing a small part of these questions. It...
