Co-operative managers face an increasingly heterogeneous pool of poten
tial members. Because these members bring a variety of economic and no
neconomic demands to their co-operative, managers must know how differ
ent member characteristics and performance perceptions influence their
decision to patronize a co-operative This study applies three models
of co-operative patronage to survey data from rural al Alberta. A Pois
son regression is used to determine the factors that explain the numbe
r of co-operatives used, while an index of co-operative patronage meas
ures the relative intensity of co-operative versus proprietary firm us
age. A third model contucts a Tobit analysis of the amount of business
conducted with each of several different types of co-operatives. The
results show that older farmers tend to partonize move co-operatives,
and larger farms do a greater shave of their business with co-operativ
es than do smaller firms. Farmers who believe co-operatives offer inno
vative products and services are more likely to patronize them, while
a belief that co-operatives should play an active role in noneconomic
matters is not important.
