The Relation Between Accounting Comparability and Firm Productivity
研究了1992至2015年美国制造业企业中会计可比性与生产率的关系，发现会计可比性通过改善库存管理提升生产率，且该关系在同行生产率高、产品相似度高或竞争激烈时更强。
Using a comprehensive sample of U.S. manufacturing firms from 1992 to 2015, I test for the association between accounting comparability and firm productivity. I posit that increased accounting comparability facilitates learning from peer firms ultimately increasing firm productivity. Results show that accounting comparability is positively related to firm productivity and that one channel for this relation is improvement in inventory management. In cross-sectional analysis, I find that the relation between accounting comparability and firm productivity is stronger when (a) peer firms exhibit higher productivity and provide more informative filings; (b) subject firms exhibit higher product similarity with peer firms and face stiffer competition, and (c) subject firms operate in industries characterized by higher accounting quality.
