Title: The Role of Accounting Information in Stock Market Liberalization: Evidence from Korea
Abstract: A stock market liberalization is a decision by a country's government to allow foreigners to buy securities in that country's capital market. This study examines how the liberalization of the Korean stock market affected stock price behavior and changed the role accounting information for investment decisions. The Korean stock market opened its door to foreign investment in 1991. Prior to this, market inefficiencies, such as the co-movement of stock prices with industry or market indices or investment based on rumor and speculation, were widespread. Since the opening of the stock market to foreigners, a more rational pricing behavior has emerged. This setting provides a unique opportunity to investigate how stock price behavior has changed with market liberalization and what was the role of accounting information in this process. Our results indicate that the co-movement behavior of stock prices by industry decreased and stock price differentiation based on individual firm characteristics increased after market liberalization. The results also show that the explanatory power of accounting numbers increased after market liberalization. Overall, the results imply that foreign investors contributed to the improvement of market efficiency with the opening up of capital markets in Korea. We believe that our results provide useful evidence to other capital markets that are in a similar situation.
