|October 2019||Does Costly Reversibility Matter for U.S. Public Firms?|
with Hang Bai, Chen Xue, Lu Zhang: w26372
Yes, most likely. The firm-level evidence on costly reversibility is even stronger than the prior evidence at the plant level. The firm-level investment rate distribution is highly skewed to the right, with a small fraction of negative investments, 5.79%, a tiny fraction of inactive investments, 1.46%, and a large fraction of positive investments, 92.75%. When estimated via simulated method of moments, the standard investment model explains the average value premium, while simultaneously matching the key properties of the investment rate distribution, including the cross-sectional volatility, skewness, and the fraction of negative investments. The combined effect of costly reversibility and operating leverage is the key driving force behind the model’s quantitative performance.
|February 2006||Optimal Market Timing|
with Dmitry Livdan, Lu Zhang: w12014
We use a fully-specified neoclassical model augmented with costly external equity as a laboratory to study the relations between stock returns and equity financing decisions. Simulations show that the model can simultaneously and in many cases quantitatively reproduce: procyclical equity issuance; the negative relation between aggregate equity share and future stock market returns; long-term underperformance following equity issuance and the positive relation of its magnitude with the volume of issuance; the mean-reverting behavior in the operating performance of issuing firms; and the positive long-term stock price drift of firms distributing cash and its positive relation with book-to-market. We conclude that systematic mispricing seems unnecessary to generate the return-related evidence...
