Using data from the 1986 oil price decrease, I examine the capital exp
enditures of nonoil subsidiaries of oil companies. I test the joint hy
pothesis that 1) a decrease in cash/collateral decreases investment, h
olding fixed the profitability of investment, and 2) the finance costs
of different parts of the same corporation are interdependent. The re
sults support this joint hypothesis: oil companies significantly reduc
ed their nonoil investment compared to the median industry investment.
The 1986 decline in investment was concentrated in nonoil units that
were subsidized by the rest of the company in 1985.
