Management skill and strong team building abilities are often perceived as essential leadership attributes for successful entrepreneurs. Robert B. Reich considers leadership, management ability, and team-building as essential qualities of an entrepreneur. This concept has its origins in the work of Richard Cantillon in his Essai sur la Nature du Commerce en (1755) and Jean-Baptiste Say in his Treatise on Political Economy.
Psychological studies show that the psychological propensities for male and female entrepreneurs are more similar than different. A growing body of work shows that entrepreneurial behavior is dependent on social and economic factors. For example, countries with healthy and diversified labor markets or stronger safety nets show a more favorable ratio of opportunity-driven rather than necessity-driven women entrepreneurs. Empirical studies suggest that male entrepreneurs possess strong negotiating skills and consensus-forming abilities.
Research studies that explore the characteristics and personality traits of, and influences on, the entrepreneur have come to differing conclusions. Most, however, agree on certain consistent entrepreneurial traits and environmental influences. Although certain entrepreneurial traits are required, entrepreneurial behaviours are also dynamic and influenced by environmental factors. Shane and Venkataraman (2000) argue that the entrepreneur is solely concerned with opportunity recognition and exploitation, although the opportunity that is recognised depends on the type of entrepreneur; while Ucbasaran et al. (2001) argue there are many different types contingent upon environmental and personal circumstances.
Jesper Sørensen has argued that some of the most significant influences on an individual's decision to become an entrepreneur are workplace peers and the social composition of the workplace. In researching the likelihood of becoming an entrepreneur based upon working with former entrepreneurs, Sørensen discovered a correlation between working with former entrepreneurs and how often these individuals become entrepreneurs themselves, compared to those who did not work with entrepreneurs. The social composition of the workplace can influence entrepreneurism in workplace peers by proving a possibility for success, causing a “He can do it, why can’t I?” attitude. As Sørensen stated, “When you meet others who have gone out on their own, it doesn’t seem that crazy.” 
Perception of entrepreneurs
The ability of entrepreneurs to innovate is thought to relate to innate traits such as extroversion and a proclivity for risk-taking. According to Schumpeter, the capabilities of innovating, introducing new technologies, increasing efficiency and productivity, or generating new products or services, are characteristic qualities of entrepreneurs. Entrepreneurs are catalysts for economic change, and researchers argue that entrepreneurs are highly creative individuals with a tendency to imagine new solutions by finding opportunities for profit or reward. Largely due to the influence of Schumpeter's heroic conceptions of entrepreneurs, it is widely maintained that entrepreneurs are unusual individuals. In line with this view, there is an emerging research tradition investigating the genetic factors that are perceived to make entrepreneurs so distinctive (Nicolaou and Shane, 2009).
However, there are also critical perspectives that attribute these research attitudes to oversimplified methodological and/or philosophical assumptions (Gartner, 2001). For example, it has been argued that entrepreneurs are not that distinctive, but that it is in essence unrealistic preconceptions about "non-entrepreneurs" that maintain laudatory portraits of "entrepreneurs" (Ramoglou, 2011).
