Presidential Address: Discount Rates
JOHN H. COCHRANE
ABSTRACT
Discount-rate variation is the central organizing question of current asset-pricing research.
I survey facts, theories, and applications. Previously, we thought returns were
unpredictable, with variation in price-dividend ratios due to variation in expected
cashflows. Now it seems all price-dividend variation corresponds to discount-rate
variation. We also thought that the cross-section of expected returns came from the
CAPM. Now we have a zoo of new factors. I categorize discount-rate theories based
on central ingredients and data sources. Incorporating discount-rate variation affects
finance applications, including portfolio theory, accounting, cost of capital, capital
structure, compensation, and macroeconomics.
