Most recent studies investigating pattern bargaining have sought to es
tablish its presence or absence by statistically comparing summary mea
sures of wage levels or growth rates across and within industries. The
author of this study argues that a better measure of the existence of
pattern bargaining over wages is the degree of similarity of collecti
ve bargaining contract clauses-the usual focus of negotiators when the
y engage in pattern-following. Using that criterion, he analyzes UAW a
nd IAM collective bargaining agreements in the automobile, aerospace,
and agricultural implement industries for the years 1970-95. He finds
evidence that a strong wage pattern existed at both the inter- and int
raindustry levels in the 1970s, but that this pattern weakened in the
1980s. Among the major automobile industry bargaining pairs, however,
a strong intra-industry pattern returned in the late 1980s.
