D. The change in money supply in the economy
The explanatory variables were
• The spread between long-term and short-term interest rates (reflecting shifts in time preferences);

• Industrial production (reflecting changes in cash flow expectations); and
• The spread between high-risk and low-risk corporate bond yields (reflecting changes in risk preferences).
