Theoretical and empirical works on capital mobility, characterizing the relationship between savings and investments, are systematized. Own econometric calculations of the relationship between savings and investments were carried out on a sample of OECD countries, developing countries, countries with a high dependence on hydrocarbon exports. In general, the results of the empirical analysis indicate an increase in capital mobility over time, but after the global financial crisis, capital mobility declined again. Greater capital mobility is characteristic of developing countries and countries with high dependence on hydrocarbons. The paper also systematizes theoretical and empirical work to identify the role of uncertainty in the dynamics of macroeconomic indicators. Based on estimates based on cross-country data, it was found that the volatility of the terms of trade negatively affects the rate of economic growth.
