Classical theories predict rapid price adjustments, which are observed
in inflationary episodes; Keynesian theories of sticky prices predict
sluggish price responses, which are observed in contractions. We atte
mpt to reconcile these observations in a model with asymmetries in pro
ducer price and output adjustments. Analysis of SIC two-digit industry
data indicates production frequently exhibits negative asymmetry-shor
tfalls from trend are larger than positive deviations-whereas price of
ten displays positive asymmetry. Evidence supporting two rational moti
ves for asymmetric pricing is presented, but causal interactions betwe
en output and price asymmetries are not resolved.
