Nominal wage and price adjustments in response to demand shocks are likely
to determine industrial output variability. The direction of this relations
hip is complicated, however, by demand and supply factors. The empirical in
vestigation across a sample of private industries in the United States prod
uces the following evidence. Price flexibility moderates the response of th
e output supplied to a given shift in industrial demand. Similarly, nominal
wage flexibility moderates, although insignificantly, the output response
to a given shift in industrial demand. The size of industrial demand shifts
dominates, however, supply-side constraints in differentiating output fluc
tuations across industries. While price flexibility moderates shifts in ind
ustrial demand in response to aggregate demand shocks, these shifts are lar
ger the higher the nominal wage flexibility across industries. The combined
supply and demand effects differentiate the stabilizing function of nomina
l wage and price flexibility. Nominal wage flexibility increases output flu
ctuations in response to aggregate demand shocks. In contrast, output fluct
uations are smaller the larger the price adjustment to demand shocks across
industries. Given the endogeneity of price flexibility, it is necessary to
control for variation in demand variability in order to reveal the stabili
zing effect of price flexibility on output across industries.
