This paper provides a long-term view by studying the effect of the underground or shadow economy on economic growth in the Unites States over the period 1870 to 2014. Shadow activities might spur or retard economic growth depending on their interactions with the formal sector and impacts on the...

We develop a model to understand the trade-offs faced by an elected representative in supporting an amnesty when a restrictive immigration policy is in place. We show that an amnesty is more desirable the more restricted are the occupational opportunities of undocumented immigrants and the less...

Using data on the US and EU top R&D spenders from 2004 until 2012, this paper investigates the sources of the US/EU productivity gap. We find robust evidence that US firms have a higher capacity to translate R&D into productivity gains (especially in the high-tech industries), and this...

Self-esteem has been conceptualized as a social vaccine. The belief is that high self-esteem can inoculate young people, against vulnerability to a wide range of social illnesses. This study gives a contribution in the understanding of the causal relation between self-esteem and sexual behaviour...

Self-esteem has been conceptualized as a "social vaccine". The belief is that high self-esteem can inoculate young people, against vulnerability to a wide range of social illnesses. This study gives a contribution in the understanding of the causal relation between self-esteem and sexual...

In two experiments, we examine the effects of employer reputation in an online labor market (Amazon Mechanical Turk) in which employers may decline to pay workers while keeping their work product. First, in an audit study of employers by a blinded worker, we find that working only for good...

We investigate whether the publicly available information on Facebook about job applicants affects employers' hiring decisions. To this end, we conduct a field experiment in which fictitious job applications are sent to real job openings in Belgium. The only characteristic in which these...

Asymmetric information between voters and legislative representatives poses a major challenge to the functioning of representative democracy. We examine whether representatives are more likely to serve long-term campaign donors instead of constituents during times of low media attention to...

We take a fresh look at firms' innovation-productivity linkages, using novel data capturing new aspects of innovative activity. We combine UK administrative microdata, media and website content to develop experimental metrics – new product/service launches – for a large panel of SMEs....
