Influence of genetic factors and institutional environment on entrepreneurial activity: evidence from a twin study in Italy
通过意大利双胞胎数据，检验了遗传因素在有利与不利制度环境下对创业活动的影响差异，发现有利制度环境会放大遗传因素的作用。
Abstract Genetic factors influence entrepreneurial activity, but we know little about how genetic factors influence entrepreneurial activity when the institutional environment is favorable. Two theories from behavioral genetics explain the gene–environment interaction. One theory argues that a favorable environment favors the development of genetic factors and their influence. An alternative theory posits that unfavorable environment triggers the development of genetic factors and their influence. I test these two competing theories with a twin study based in Italy. I compare the influence of genetic factors in provinces where the institutional environment favors entrepreneurial activity with provinces where the institutional environment is unfavorable to entrepreneurial activity. I found consistent evidence that genetic factors exert a larger influence in favorable institutional environments, suggesting that favorable institutional environments complement genetic factors.
