The fundamental change in accounting rules for equity-based compensation (EBC) instituted by SFAS 123, SFAS 123r, and IFRS 2 has allowed for new insights related to a variety of research questions. This paper discusses the empirical evidence generated in the wake of the new regulation and categorizes it into two broad streams. The first stream encompasses research on the changed use of EBC and the incentives provided. The second stream addresses how firms account for EBC, including the underreporting phenomenon and how it was affected by the mandatory recognition of EBC expenses. I discuss where research delivers unanimous findings versus contradictory results. Using these insights, I make recommendations for further research opportunities in the area of EBC.

我们从SFAS 123r和IFRS 2中学到了什么？审查现有证据和未来研究建议

SFAS 123，SFAS 123r和IFRS 2制定了基于权益的薪酬（EBC）会计规则的根本变化，这为与各种研究问题相关的新见解提供了可能。本文讨论了新法规产生的经验证据，并将其分为两大类。第一阶段包括对EBC用途改变和提供的激励措施的研究。第二部分讨论企业如何计算EBC，包括漏报现象以及强制确认EBC费用如何影响它。我讨论了研究在何处得出一致的结论与矛盾的结果。利用这些见解，我为EBC领域的进一步研究机会提出了建议。
