Corporate international diversification theory posits that multinational co
rporations (MNCs) should have lower risk and higher financial leverage than
purely domestic corporations (DCs). We suggest an alternative upstream-dow
nstream hypothesis according to which the overall effect of internationaliz
ation on the risk and leverage of MNCs is expected to vary with home and ta
rget market conditions. The empirical results are consistent with the sugge
sted hypothesis.
