Widespread attention is being paid to the alleged rise of narcissism in people in general and business leaders in particular. Surprisingly, hardly any studies have focused on the link between narcissism and entrepreneurship. Using self-reported data from 4798 respondents from three countries, we explore the associations between trait narcissism and...

There is a small body of literature linking attention‐deficit hyperactivity disorder (ADHD) and its symptoms to entrepreneurial manifestations. Some studies take a subclinical perspective by studying the presence of symptoms, while other studies take a clinical perspective by studying the formal diagnosis of ADHD. The entrepreneurial manifestations...
Article
Recent studies have shown that individuals with attention deficit hyperactivity disorder (ADHD) are relatively often engaged in self-employment. We analyze whether self-employment mediates the relationship between ADHD and earnings. To overcome endogeneity concerns in the estimation of this relationship, we use the polygenic risk score (PRS) for AD...

A growing conversation has emerged linking ostensibly dark or pathological individual-level characteristics to entrepreneurship.

Attention-deficit/hyperactivity (ADHD) symptoms have been associated with the decision to become self-employed. Although these symptoms are generally regarded as disadvantageous, there may also be a bright side. To our knowledge, however, there has been no systematic, epidemiological evidence to support this claim. This paper examines the associati...

Research on organizational ambidexterity has introduced various approaches for organizations to combine exploratory and exploitative activities.
