In this paper, the authors investigate the impact of demand fluctuations on market power in U.S. manufacturing industries. They impose on a model with adjustment costs the minimum structure necessary to recover a measure of markups. Markups are allowed to vary with both the state and future evolution of demand and estimates of price-cost margins are obtained from the Euler equation for capital. The authors conduct the empirical investigation for U.S. two-digit manufacturing industries using annual data covering the 1952-85 period. They find that markups are inversely related to current demand. However, given the state of demand, they vary directly with expectations of future demand changes.
