Corporate credit lines are drawn more heavily when funding markets are more stressed. This covariance elevates expected bank funding costs. We show that credit supply is dampened by the associated debt-overhang cost to bank shareholders. Until 2022, this impact was reduced by linking the...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...

This paper shows that there is more scope for a borrower to engage in a sustainable infinite debt rollover (a "Ponzi scheme") when interest/growth rates are stochastic. In this context, I prove that the relevant "r vs. g" comparison uses the yield r_{long} to an infinite-maturity zero-coupon...

The fall in the U.S. public debt/GDP ratio from 106% in 1946 to 23% in 1974 is often attributed to high rates of economic growth. This paper examines the roles of three other factors: primary budget surpluses, surprise inflation, and pegged interest rates before the Fed-Treasury Accord of 1951....

We use equity returns to construct a time-varying measure of the interest rate that we call the zero-beta rate: the expected return of a stock portfolio orthogonal to the stochastic discount factor. The zero-beta rate is high and volatile. In contrast to safe rates, the zero-beta rate fits the...

We develop a two-country model in which currency and bond markets are populated by different investor clienteles, and segmentation is partly overcome by global arbitrageurs with limited capital. Our model accounts for the empirically documented violations of Uncovered Interest Parity (UIP) and...
