Getting the Incentives Right: Backfilling and Biases in Executive Compensation Data
研究发现ExecuComp数据库的回填操作会导致数据条件偏差,高估异常薪酬和薪酬业绩敏感性,并扭曲理论检验结果,提出了修正方法。
We document that backfilling in the ExecuComp database introduces a data-conditioning bias that can affect inferences and make replicating previous work difficult. Although backfilling can be advantageous due to greater data coverage, if not addressed, the oversampling of firms with strong managerial incentives and higher subsequent returns leads to a significant upward bias in abnormal compensation, pay-for-performance sensitivity, and the magnitudes of several previously established relations. The bias also can lead to one misinterpreting the appropriate functional form of a relation and whether the data support one compensation theory over another. We offer methods to address this issue.
