Using ordered probit analyses of a unique micro data set, we find evid
ence of output asymmetry that is systematically related to inflation a
nd to price asymmetry. As predicted by theory, firms are more likely a
t higher rates of inflation to raise prices in response to positive co
st and demand shocks and less likely to lower prices in response to ne
gative cost and demand shocks. The expected effects of higher inflatio
n on output asymmetry, however, come primarily from cost and demand in
creases and to a lesser (and statistically, insignificant) extent from
cost and demand decreases.
