I hypothesize that risk taking is greater in stock thrifts than in mut
ual thrifts because the residual and fixed claims are separable. I fin
d that stock thrifts exhibit greater profit variability during the 198
2-88 period and that conversions from mutual to stock ownership are as
sociated with increased investment in risky assets and increased profi
t variability. These findings illustrate the relation between the stru
cture of residual claims, incentives, and firm performance as well as
the unintended consequences resulting from changes in thrift regulatio
ns.
