After working well for more than 5 years, the Fisher Body-General Motors (G
M) contract for the supply of automobile bodies broke down when GM's demand
for Fisher's bodies unexpectedly increased dramatically. This pushed the i
mperfect contractual arrangement between the parties outside the self-enfor
cing range and led Fisher to take advantage of the fact that GM was contrac
tually obligated to purchase bodies on a cost-plus basis. Fisher increased
its short-term profit by failing to make the investments required by GM in
a plant located near GM production facilities in Flint, Michigan. Vertical
integration, with an associated side payment from GM to Fisher, was the way
in which this contractual hold-up problem was solved. This examination of
the Fisher-GM case illustrates the role of vertical integration in avoiding
the rigidity costs of long-term contracts.
