We analyze whether the passage of a Norwegian law requiring a minimum of a 40 percent of women on the boards of public firms affected financial reporting quality. Our results are consistent with a decrease in financial reporting quality for the firms that were most affected by the passage of the law, and with the effects being relatively short-lived. We also find evidence that board members characteristics, beyond gender, changed due to this law. These changes can partially explain our findings. Overall, our results show that mandating large changes to board composition over a relatively small period of time negatively affects financial reporting.

对董事会实施（性别）配额对财务报告质量的影响

我们分析了挪威法律要求上市公司董事会中至少有 40% 的女性是否会影响财务报告的质量。我们的结果与受法律通过影响最大的公司的财务报告质量下降一致，并且影响相对短暂。我们还发现有证据表明，董事会成员的特征，除了性别，由于这项法律而发生了变化。这些变化可以部分解释我们的发现。总体而言，我们的研究结果表明，在相对较短的时间内强制对董事会组成进行大幅调整会对财务报告产生负面影响。
