Intergovernmental organizations (IGOs) promote stability, development, and security for member states and their citizens via supranational institutional influences. However, their impact on individuals has been questioned due to political, social, and economic uncertainties. We study how IGOs influence entrepreneurial decision-making. Using a robust sample of 68 countries, their entrepreneurial environment, and their connection to IGOs, we find that IGOs cultivate a positive environment for entrepreneurship. Moreover, IGOs encourage different strategic decisions - encouraging formal entrepreneurship while discouraging informal entrepreneurship. We combine insights from international relations, institutional theory, and strategic entrepreneurship to highlight how institutions at different levels influence entrepreneurial decision-making.
