Are U.S. GAAP-based and IFRS-based accounting amounts more comparable after the revised lease standards? Evidence from ASC 842 and IFRS 16
研究了修订后的租赁准则（ASC 842和IFRS 16）是否提高了美国GAAP与IFRS会计金额的可比性，发现高经营租赁用户的可比性提升更大，且主要来自资产负债表变化，对执法严格国家的IFRS企业影响更显著。
Abstract This study examines whether the revised lease standards (ASC 842 and IFRS 16) make U.S. GAAP-based accounting amounts more comparable with IFRS-based accounting amounts. Our study is motivated by the FASB and the IASB’s call for research on the comparability of the revised lease standards. We find that U.S. GAAP and IFRS pairs that are high operating lease users experience a larger increase in accounting comparability after the adoption of revised lease standards than low operating lease U.S. GAAP-IFRS pairs. Additionally, our results suggest that the improvement comes more from the changes to the balance sheet rather than the income statement and is more pronounced for IFRS firms from countries with stronger accounting enforcement. Lastly, we show that analysts who are more GAAP-focused (IFRS-focused) prior to the standard change are more likely to increase their forecasting of book value per share for IFRS (U.S. GAAP) firms.
