We tested for the capture of net gains by winners in rent-seeking comp
etitions, using the most prominent announcements of government favors
in the Canadian economy over a twelve-year period. Stockholders' retur
ns were not significantly different from zero. One possible explanatio
n is that government assists firms only when assistance creates politi
cal gains. Refusing to transfer economic rents to firms maximmizes the
resources available to serve political purposes. This kind of behavio
r by government officials would imply that government has market power
, which is consistent with several well-known theories of government.
