연구실 소개

정수미 교수의 연구실은 기업 지배구조와 임원 보상 구조, 특히 외부 일자리 제약이 CEO의 위험 회피 성향에 미치는 영향을 다룹니다. 특히 미국 주법원에서 점진적으로 도입된 불가피한 공개 원칙(Illegal Disclosure Doctrine, IDD)을 자연 실험처럼 활용해, 보수 구조의 변동, 특히 주가 변동성에 대한 민감도(vega) 변화를 분석합니다. 또한 정치적 연결망이 기업의 회계 선택에 미치는 영향, 특히 부정적 여론을 피하기 위한 수익 smoothing 행동의 존재를 규명하며, 경영자의 능력이 세금 회피 조정 속도에 미치는 영향을 분석하는 연구도 수행합니다. 이와 같은 연구들은 기업의 의사결정, 리스크 행동, 정치적 영향력이 보상 및 회계 정책에 어떻게 반영되는지를 탐구합니다.

Outside Opportunities, Managerial Risk Taking, and CEO Compensation
Wen Chen, Sumi Jung, Xiaoxia Peng, Ivy Xiying Zhang
SJR Q1The Accounting Review

ABSTRACT Exploiting the setting of staggered adoption of the Inevitable Disclosure Doctrine (IDD) in U.S. state courts, we examine how quasi-exogenous restrictions of outside employment opportunities affect CEO compensation structure. The IDD adoption constrains executives' ability to work for competitors, which likely decreases CEOs' tendency to take risks by increasing the cost of job loss and reducing the reward to risk taking. We expect the board to respond by increasing the sensitivity of C

Powerful Politicians, Political Costs, and Income Smoothing
Sumi Jung
SJR Q1The Accounting ReviewOA

ABSTRACT This paper investigates whether and how firms receiving benefits through their connections to politicians use accounting discretion to mitigate the costs associated with negative publicity. I utilize a unique setting that captures the change in political costs arising from chairmanship appointments to influential U.S. Senate committees. Firms in the home state of a promoted officeholder often receive preferential treatment, drawing public scrutiny and incentivizing them to avoid reporti

Managerial ability and tax avoidance adjustment toward the optimal level
Ji Yeon Lee, Sumi Jung, Hyungjin Cho
SJR Q3Spanish Journal of Finance and Accounting / Revista Española de Financiación y ContabilidadOA

Highlighting managerial ability as a moderator of tax adjustment behaviour, this study finds that firms led by more capable managers exhibit slower adjustment speed of tax avoidance towards the optimal level. Furthermore, our findings remain robust after employing the propensity score matching and instrumental variable approaches. Cross-sectional analysis reveals that the negative association between managerial ability and tax avoidance adjustment speed is stronger for firms facing larger transa

Determine the preference ordering of the stocks listed in KOSPI with TOPSIS
G. T. Kim, Sumi Jung, S. H. Cho

Recently, most of the stock markets all over the world have ever experienced the worst situation since the great depression of 1929. Some of the stock market indices have dropped down to the half of the indices achieved in October of 2007. This kind of rapid downfalls in the stock markets has been happening in the southeastern Asia including Korea and Chine. With this in mind, we tried to figure out how to make the sound investment in stocks from a decision-making theorist perspective. To this e

The Effect of Financial Statement Comparability on Cost Stickiness
Heung‐Jae Jeon, Sumi Jung
SJR Q1Journal of International Financial Management and AccountingOA

ABSTRACT This study examines the impact of financial statement comparability on asymmetric cost behavior, commonly known as cost stickiness. Using a comprehensive U.S. sample (1999–2020), we document a positive association between greater comparability and increased cost stickiness. The relationship is markedly stronger for firms facing high uncertainty and for firms whose analyst forecasts are less accurate or more dispersed. We also find that higher comparability notably raises the likelihood

Does Securities Class Action Encourage Accounting Conservatism?
정수미, 이정은, 추형석
경영컨설팅연구

This paper examines the impact of litigation risk on accounting conservatism using the two-phase enactment of Securities Class Action in Korea. Using the sample of firms listed on KOSPI and KOSDAQ from 2002 to 2010, we demonstrate that the increased legal risk subsequent to the implementation of Securities Class Action encourages managers to adopt a more conservative financial reporting. In addition, we find that the increase in accounting conservatism following Securities Class Action enactment
