In this empirical paper, we take a close look at the impact of the observed decline in the product market regulation, and hence in the barriers to entry and in impediments to competition, on inflation dynamics since the early 1980s.

Introducing costs of entry in the product market into a New Keynesian model with Calvo-type price setting and non zero steady state inflation is a means to restore output costs of disinflation in the short run, before output gains in the long run.
