To identify possible equity market implications of restrictions on foreign ownership and investment in Russia, as well as against Russian ownership abroad, we reviewed data from 38 countries and applied fixed effects models to panel data. We show that restrictive measures against foreign ownership and investment will have a negative impact on the capitalization of the domestic stock market. The effect will be amplified under the influence of such factors as corruption, freedom of investment, financial, trade and business freedoms. The quality of the judiciary is most important when examining the share of the domestic stock market in the world stock market. Tax incentives and increased fiscal freedom will not be able to have a positive impact in the face of restrictive measures against foreign ownership and investment. © 2023, Russian Presidental Academy of National Economy and Public Administration.
