This paper studies the relationship between corporate social responsibility and financial performance with a focus on the experience of CSR reporting in Korea. The sample size for this study consisted of 183 firms in Korea during the period covering 2006-2009, using the KEJI index as CSR performance proxy. Specifically, this study examined the effect of CSR performance on subsequent financial performance and the effect of subsequent financial performance on CSR performance in Korean firms. The next phase of the study looked into the differences between firms that do CSR reporting and those that do not. In conclusion, the findings suggest that CSR performance is positively associated with some aspects of subsequent financial performance In addition, results showed that: (1) there is no effect in expediency of CSR reporting; (2) CSR performance is positively associated with prior financial performance more thus strongly supporting the slack resource theory.

In this paper, we analyze the currency risk exposure borne by the Korean manufacturing firms that are listed in Stock Market at Korea Exchange. More specifically, we use the data from 1994 to 2002 to measure the extent of currency risk exposure, and investigate the factors that are known to affect the degree of exposure. Note that after the currency crisis that occurred around December 1997, the exchange rate regime for Korean Won changed from the managed float to the free float. Therefore, the data provide a natural experimental ground to investigate whether the firms react to the fundamental changes in the international monetary system. One of the features of this paper is that we use the trade-weighted exchange rates, namely JP Morgan Index of Korean Won to measure the currency risk more accurately. In order to measure the exposure, we estimate the sensitivity of stock returns to the changes in the local currency value. In order to do so, we base our analyses on the empirical model developed by He and Ng (1998). First we find that the currency beta actually decreases after the free float is adopted. This is surprising in that the exchange rate volatility actually increased dramatically after the flexible exchange rate regime was adopted. Second, when we conduct the cross-sectional analysis of the estimated currency beta against firm characteristics, we find that prior to the currency crisis, the currency beta is negatively related to the firm size, Book- to-Market ratio, dividend yield, and positively related to the quick ratio, but none of these factors become statistically significant after the free float was adopted. These findings imply that even though the exchange rate volatility increased with the introduction of flexible exchange rate regime, the currency risk exposure actually decreased at the firm level. Whether the reduction of the risk exposure results from the improved skills in managing risks is an interesting question, but we believe that this is beyond the scope of this paper and left for future research.
