We study the effects of monetary-policy-induced changes in Tobin's q on corporate investment and capital structure. We develop a theory of the mechanism, provide empirical evidence, evaluate the ability of the quantitative theory to match the evidence, and quantify the relevance for monetary...

Using firm-level administrative tax data on the 43% of business liabilities in the United States tied to privately held firms, we document dramatic reductions in leverage since the Great Recession. Leverage for the average private firm fell fifteen percent between 2004 and 2018. In contrast,...
