The document discusses two hypotheses for what drives corporate social responsibility (CSR) performance among companies: the globalist hypothesis that CSR is driven by globalization pressures, and the institutionalist hypothesis that CSR is influenced by national institutions. The author finds support for both hypotheses. Countries with high proportions of transnational corporations and outward foreign investment tend to have high CSR scores, supporting the globalist view. Countries with strong social, corporatist and political cultures also tend to have high CSR scores, supporting the institutionalist perspective. There are likely multiple causal factors and paths leading to high CSR.
