Only a few papers have examined the relationship between inflation unc
ertainty and contract duration, and the results are mixed. Here the us
ual specification is modified by using a relative measure of uncertain
ty, including a dummy to test Danziger's (1988) conclusion that higher
uncertainty about real factors increases contract duration, and inclu
ding squared uncertainty to test Harris and Holmstrom's (1987) claim o
f a U-shaped relationship. For the entire sample there is a robust neg
ative relation between contract duration and inflation uncertainty. Ho
wever, even with the above modifications there is little evidence of a
ny relation in two-digit SIC samples.
