收藏资源简介:
This dataset contains firm-level financial and tax-related variables for Korean listed firms, including KOSPI, from 2011 to 2024.

Users should account for missing years in their empirical analysis. Contents: Firm characteristics: ownership, size, leverage, growth, profitability, etc. Tax avoidance measures: Cash ETR, GAAP ETR, Total and Discretionary book-tax differences (TSTA, TSDA). Balance sheet and market-based indicators (Tobin’s Q, MB ratio, etc.). File format: CSV / XLSXUnit of observation: Firm-year This dataset can be used in research on tax avoidance, corporate governance, financial performance, and ESG-related studies.
