Dynamic pricing equations are estimated using an error correction model, wi
th data on a panel of 89 Australian manufacturing industries for the 14 yea
rs, 1971/72 through 1984/85. The overall pattern is consistent with prices
approximately following a fixed mark-up rule in low concentration industrie
s, while the mark-up factor in high concentration industries is strongly pr
o-cyclical. Also, in high concentration industries that are heavily exposed
to import competition, the mark-up factor ina eases with prices of foreign
competing products and with the general price level for domestic manufactu
res.
