This paper surveys the theoretical principals of the capital account liberalization and evaluate the literature on the effects of capital account openness on economic growth. Following the evaluation of literature, various measurements of capital account liberalization are discussed. After reviewing various measurements it can be seen that most countries have, to a great extend, opened their accounts to capital flows. But this paper shows that the empirical studies failed to provide evidence that there is a strong and prominent effect of capital account liberalization on economic growth. Despite the empirical studies, experimental studies analyzing the developments after liberalization in countries found that opening the capital account has an important effect on GDP.
