I develop and test a new machine learning method for estimating cross-sectional firm-level expected returns. My approach adapts the loss function of a random forest algorithm to minimize the variance of measurement errors instead of trading off bias and variance. This approach yields higher...

We study whether the corporate tax system provides incentives for risky firm investment. We first model the effects of corporate tax rates and tax loss offset rules on firm risk-taking. Testing the theoretical predictions, we find that firm risk-taking is positively related to the length of tax...

We study whether the corporate tax system provides incentives for risky firm investment. We analytically and empirically show two main findings: first, risk-taking is positively related to the length of tax loss periods because the loss rules shift some risk to the government; and second, the...
