Vliv bariér v oblasti zahraničního obchodu a investic ze zahraničí na HDP na obyvatele ve vybraných zemích OECD v letech 2018 a 2023

This thesis analyzes the relationship between regulatory barriers to trade and investment and economic performance across 50 countries in 2018 and 2023. It uses the Barriers to Trade and Investment indicator from the OECD Product Market Regulation framework, the natural logarithm of GDP per capita in constant 2015 US dollars, and a balanced panel of 100 observations. It compares pooled OLS, fixed-effects, and random-effects models, each including eight control variables. The main fixed-effects model indicates a negative and statistically significant relationship: holding the other variables constant, a 0.1-point increase in the barrier index is associated with approximately 2.2% lower GDP per capita. The stability of the main result is assessed through a robustness check that includes the rule of law indicator as a measure of the quality of the legal environment. The contribution of the thesis lies in providing an empirical assessment of the relationship between the OECD PMR sub-indicator Barriers to Trade and Investment and the natural logarithm of GDP per capita using a balanced panel of 50 countries while accounting for selected macroeconomic characteristics.
