Cross-Country Determinants of Early-Stage Necessity and Opportunity-Motivated Entrepreneurship: Accounting for Model Uncertainty
研究了44个可能影响早期阶段机会型和必要型创业的因素，发现经济自由相关的制度变量最稳健，收入不平等和斯堪的纳维亚法律起源也有一定预测力。
Model uncertainty is one of the most pervasive challenges in the social sciences. Cross-country studies in entrepreneurship have largely ignored this issue. In this paper, we evaluate the robustness of 44 possible determinants of early-stage opportunity-motivated entrepreneurship (OME) and necessity-motivated entrepreneurship (NME) that are broadly classified in four groups: (1) economic variables, (2) formal institutions, (3) cultural values, and (4) legal origins and geography. The results, which are based on a representative world sample of up to 73 countries, suggest that institutional variables associated with the principles of economic freedom are most robustly correlated with OME and NME. Our findings also identify net income inequality and Scandinavian legal origins as weakly robust predictors of both types of entrepreneurial activity. Furthermore, we find that log GDP per capita is only a weakly robust predictor of NME, but not OME. We discuss implications for future research.
