摘要：The paper examines the differential exercise of market power over the business cycle in the context of selected sectors in the Canadian manufacturing industry during the 1992-1/2007-4 period. In particular, empirical implications of non-collusive models previously explored by Wilson and Reynolds (2005) are further investigated by considering data for selected disaggregated and homogeneous sectors and is consistent with a multiple regimes formulation. A main implication concerning differential variances for changes in prices in the two demand regimes is partially supported in the investigated sectors.
