研究室紹介

Professor Won-Ja Song's research lab specializes in corporate governance, audit quality, and behavioral corporate finance, with a strong focus on the interplay between executive behavior, risk perception, and financial reporting quality. The lab investigates how managerial myopia—particularly through practices like ESG-washing—and auditor decision-making, especially under asymmetric cost behavior, affect firm value and audit outcomes. Current research explores the role of audit firm characteristics, such as Big 4 status and industry specialization, in shaping audit effort and fees in response to earnings management incentives.
