The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults ...
Publishing entrepreneurship research is not just important but challenging. Longstanding experts in the field can provide helpful advice. As borders between academic fields blur, research fields are increasingly global in their perspective, knowledge, and findings, thus enabling robust participation in research fields at a scale previously unimaginable. Drawing on the experience, insights, and perspectives ...
Many industries are seeing an increase in concentration, leading to a discussion on the effectiveness of horizontal merger enforcement. The policy debate shows that one of the key arguments put forward when supporting potential mergers is the possibility of realization of merger efficiency gains, specifically in the transport industry. Yet, there exists little empirical evidence on the actual effects ...
Labor markets in low- and middle-income countries are characterized by high levels of informality. A multitude of interventions have been implemented to increase the formalization of firms and workers, including information campaigns, simplified registration procedures, reductions of payroll taxes, and interventions enforcing formalization. We compile a database of 170 impact estimates from 38 academic ...
The 2D:4D digit ratio, the ratio of the length of the 2nd digit to the length of the 4th digit, is often considered a proxy for testosterone exposure in utero. A recent study by Nicolaou et al. (2018) reported an association between the left-hand 2D:4D and self-employment (in a sample of about 1,000 adults). In this pre-registered study we replicate these results on a new and larger sample of about ...

After failing to fully recover from the last financial crisis, the pandemic poses major new challenges for banks. However, this time, banks are not the problem, but part of the solution. By providing credit to the economy, banks play a crucial role in fighting the pandemic by ensuring the transmission of fiscal and monetary stimulus to the economy. Nevertheless, banks are not among the winners of...
This paper contributes to the debate on the internationalization of the R&D activity of multinational enterprises (MNEs). Specifically, we examine the following research questions: (1) What are the determinants of the MNEs’ R&D internationalization level? (2) What types of internationalization strategies—home-base-augmenting (HBA), home-base-exploiting (HBE), technology-seeking (TS), and/or market-seeking ...
By developing a taxonomy for sustainable investments, the EU Commission has created the first standardized criteria for climate-friendly economic activities.To achieve the goal of climate neutrality by 2050, firms and investors must be well informed of which investments avoid greenhouse gas emis- sions and can thus be categorized as sustainable. The present report investigates to what extent the EU ...
We investigate the impact of a differential treatment of paid employees versus self-employed workers in a public health insurance system on the entry rate into self-employment. Health insurance systems that distinguish between the two sectors of employment create incentives or disincentives to start a business for different individuals. We estimate a discrete time hazard rate model of entry into self-employment ...
