The Role of Accounting Conservatism in the Decreasing Book Equity of U.S. Firms

We offer a novel explanation for the widespread decline in U.S. firms’ reported book equity. We find that accounting conservatism is negatively associated with book equity, a result that is both economically and statistically significant, as well as robust to a variety of model specifications. Our findings suggest that the rise in accounting conservatism has significantly contributed to the declines in book equity over the decades.
