Investment Plans and Stock Returns
Published: 12/17/2002 | DOI: 10.1111/0022-1082.00304

When the discount rate falls, investment should rise. Thus with time‐varying discount rates and instantly changing investment, investment should positively covary with current stock returns and negatively covary with future stock returns. Aggregate nonresidential U.S. investment contradicts both these implications, probably because of investment lags. Investment plans, however, satisfy both implications. These investment plans, from a U.S. government survey of firms, are highly informative measures of expected investment and explain more than three‐quarters of the variation in real annual aggregate investment growth. Plans have substantial forecasting power for excess stock returns, showing that time‐varying risk premia affect investment.
The Diversification Discount: Cash Flows Versus Returns
Published: 12/17/2002 | DOI: 10.1111/0022-1082.00386
Owen A. Lamont, Christopher Polk
Diversified firms have different values from comparable portfolios of single‐segment firms. These value differences must be due to differences in either future cash flows or future returns. Expected security returns on diversified firms vary systematically with relative value. Discount firms have significantly higher subsequent returns than premium firms. Slightly more than half of the cross‐sectional variation in excess values is due to variation in expected future cash flows, with the remainder due to variation in expected future returns and to covariation between cash flows and returns.
