E24,E3,E32 ABSTRACT In this paper we present a generalized sticky price model which allows, depending on the parameterization, for demand shocks to maintain strong expansionary effects even in the presence of perfectly flexible prices. Idioma catal à español English. Economists have tried to model sticky prices in a number of ways. In this paper we present a generalized sticky price model which allows, depending on the parameterization, for demand shocks to maintain strong expansionary effects even in the presence of perfectly flexible prices.

Modelling the Labor Market Competitive labor markets w t p t = mrs t where mrs t = σc t + ϕn t General labor market imperfections w t p t = µw t +mrs t where µw t: (log) wage markup. Keynesian macroeconomists suggest that markets fail to clear because prices fail to drop to market clearing levels when there is a drop in demand. • Real marginal cost: … In many models, prices are sticky by assumption; here it is a result. Sticky prices. Real Keynesian Models and Sticky Prices Paul Beaudry and Franck Portier NBER Working Paper No. The Keynesian Model suggests that the economy is not always at the full employment level of output, which means it could be above or below its potential. Hence sticky prices play an important role in Keynesian macroeconomic theory and new Keynesian thought. NBER Working Paper No. When a firm considers changing prices, it must consider two sets of costs. Many firms do not change their prices every day or even every month.

They believe that prices and wages are sticky, especially downward. price model with monopolistic competition, and a New Keynesian model with sticky prices. We proceed to use the model economy as an identification mechanism. I'm going to use that as background for addressing issues on financial stability and monetary policy raised by Ben Bernanke. Many firms do not change their prices every day or even every month. Sticky Wage Theory . Modern version: New-Keynesian. A Sticky-Price Model: The New Keynesian Phillips Curve Here we review the standard derivation of the new Keynes-ian Phillips curve, as based on the Calvo model.

In this paper we present a generalized sticky price model which allows, depending on the parameterization, for demand shocks to maintain strong expansionary effects even in the presence of perfectly flexible prices. We refer to the parameterizations where demand shocks have … In a framework similar to the Calvo model, I assume that there are two types of ﬁrms. We use search theory, with two consequences: prices are set in dollars, since money is the medium of exchange; and equilibrium implies a nondegenerate price distribution.

Noah Smith's Bloomberg post on the wonders of sticky price models caught my eye the other day. The model is constructed to incorporate the standard threeequation New Keynesian model as a special case. The New Keynesian models in wide use now typically rely on Calvo pricing (a form of time-dependent pricing), whereby monopolistically-competitive firms receive random opportunities to change prices. What set of individual shocks are necessary to account for the phase shift? New Keynesian economists, however, believe that market-clearing models cannot explain short-run economic fluctuations, and so they advocate models with “sticky” wages and prices. The stickiness of prices and wages in the downward direction prevents the economy's resources from being fully employed and thereby prevents the economy from returning to the natural level of real GDP. 1 The Sticky Price Model J.-O.Menz, L.Vogel 1 The Sticky Price Model The standard version of the New Keynesian Model is discussed in detail by Clarida et al. 1:36. Some modern economists have argued in a Keynesian spirit that, along with wages, other prices may be sticky, too. New Keynesian theories rely on this stickiness of wages and prices to explain why involuntary unemployment exists and why monetary policy has such a strong influence on economic activity. This is included in Walsh (2003), page 232 onwards, whose presentation we adopt as well.
