Abstract
AbstractWe show that the Calvo price‐setting model is not necessarily inconsistent with evidence of a weak relation between positive trend inflation and price dispersion. We identify the interaction between sticky wages and technical change as factors disrupting the allocative role of the wage system under positive trend inflation. In turn, this interaction generates inefficient wage dispersion, as opposed to price dispersion, which fuels inflation costs. We conclude that it is too early to dismiss the New Keynesian model as a useful vehicle to assess the costs of inflation.
