The log-linearized version of the basic New Keynesian model with real wage
rigidity generates a recession in response to a credible and permanent disinflation by the central bank. However, its nonlinear version implies that permanent disinflation actually leads to a boom (except when the initial steady state inflation rate is close to zero), and under real wage rigidity output increases during the adjustment to the new steady state. This paper shows
that the presence of firm entry and exit may help reconcile the log-linear and
non-linear properties of the model with respect to the output cost of disinflations. In this regard, the degree of price flexibility of incumbents versus new
entrants plays a role in determining the transitional dynamics following the
disinflation policy.
