研究室紹介

Professor Seung Hun Han's research lab specializes in corporate finance, corporate governance, and asset pricing, with a strong focus on how information asymmetry, corporate social responsibility, and ownership structures influence capital markets and investor behavior. The lab investigates the role of credit ratings, earnings management, stock repurchases, and religious influences on investment decisions, often using unique Korean and U.S. institutional data to uncover market inefficiencies and governance effects. A recurring theme is the interplay between corporate transparency, agency costs, and market reactions, particularly in emerging and developed equity markets.

Rating Agency Reputation, the Global Financial Crisis, and the Cost of Debt

SJR Q1Financial Management

Why do foreign firms obtain credit ratings by global rating agencies rather than from their home country's rating agencies even though global raters typically assign lower credit ratings when these foreign firms issue bonds in their home currencies? We find that bonds rated by a global agency decreased yields 11‐14 basis points (bps) when compared to those rated by Japanese rating agencies but, during the 2007‐2009 financial crisis, the yields on these Japanese bonds increased 12‐17 bps, thus fu

The valuation effects of corporate social responsibility on mergers and acquisitions: Evidence from U.S. target firms
Kyumin Cho, Seung Hun Han, Hyeong Joon Kim, Sang Soo Kim
SJR Q1Corporate Social Responsibility and Environmental Management

Abstract This study investigates whether a target firm's corporate social responsibility (CSR) performance creates value for shareholders. Our results indicate that target CSR performance that is stronger than that of the acquirer firm yields higher premiums for target shareholders. In addition, the positive valuation effect of CSR is more pronounced when well‐governed acquirers conduct the takeover. Our evidence is robust to several sensitivity tests. These results imply that favorable market r

Information Asymmetry, Corporate Governance, and Shareholder Wealth: Evidence from Unfaithful Disclosures of Korean Listed Firms
Seung Hun Han, Minhee Kim, Duk Hee Lee, Sangwon Lee
SJR Q3Asia-Pacific Journal of Financial Studies

Abstract In this study, we investigate firms that the Korea Exchange claims have made unfaithful disclosures. We find that such firms experience significantly negative stock price returns, suggesting that their managements exploit the information asymmetry involved in unfaithful disclosures to expropriate shareholder wealth. Our evidence shows that firms with higher management ownership experience a smaller decline in stock returns following notices of unfaithfulness, implying that corporate gov

Frequent Stock Repurchases, False Signaling, and Corporate Governance: Evidence from Korea

SJR Q1Corporate Governance An International ReviewOA

Abstract Manuscript Type Empirical Research Question/Issue We examine the relation between stock repurchases and their potential false signaling of undervaluation using unique K orean data. Research Findings/Insights We find that the firms that repurchase stocks frequently are less undervalued and have lower post‐announcement operating performance than firms that repurchase stocks infrequently. We further find that agency cost and industry‐adjusted T obin's Q of frequent repurchase firms negativ

Religious differences and households' investment decisions
Hohyun Kim, Kyoung Tae Kim, Seung Hun Han
SJR Q2The Journal of Financial Research

Abstract This study examines effects of religion on US households' investment decisions, with focusing on the two channels; individual religious belief and local religious culture. We find that Protestants are less likely to invest in stocks than nonreligious households. Catholics are more likely to participate in stock markets than nonreligious households, which is largely driven by Catholic households' greater wealth and older age. Moreover, a higher local Catholic–Protestant ratio (CPratio) i

Controlling Shareholders’ Preference in Business Groups: Evidence from Korea
Yonghyun Kwon, Seung Hun Han
SJR Q1Emerging Markets Finance and Trade

This study examines the effect of controlling shareholders’ preference on the payout policy of Korean firms. Using a sample of 9495 firm-year observations, we find that firms with individual controlling shareholders (family-owned firms) have a lower payout ratio than those with non-individual controlling shareholders. Further, firms with higher family-individual controlling shareholder ownership by individual controlling shareholders are reluctant to pay cash dividends in family business groups.
