The primary objective of this paper is to examine the major determinants of GDP growth in South Korea, emphasizing the importance of investment, trade and human capital using quarterly time series data covering the period 1980Q1 to 2005Q3. The time series properties of the data are, first, analyzed using the Zivot-Andrews (1992) model. The empirical results derived indicate that there is insufficient evidence against the null hypothesis of unit roots for all of the variables under investigation. Second, the Gregory-Hansen (1996) cointegration technique, allowing for the presence of potential structural breaks in the data, is applied, and is found to reject the null hypothesis of no cointegration relationship in favour of the existence of at least one cointegration relation in the presence of single structural breaks in the system. By applying these methodologies we find that most of the endogenously determined structural breaks coincide with the gradual effects of the Asian crisis on the Korean economy.
