Technology Shocks in the New Keynesian Model. Technology Shocks in the New Keynesian Model. Peter N. Ireland∗. Boston College and NBER August Abstract In a New Keynesian model, technology and cost-push shocks compete as terms that stochastically shift the Phillips curve.

A version of this model, estimated via maximum likelihood, points to the cost-push shock as far more important than the technology shock.

In the New Keynesian model, preference, cost-push, and monetary shocks all compete with the real business cycle model's technology shock in driving aggregate fluctuations.

A version of this model, estimated via maximum likelihood, points to these other shocks as being more important for explaining the behavior of output, inflation, and interest rates in the postwar United States by:   In the New Keynesian model, preference, cost-push, and monetary shocks Technology shocks in the new Keynesian model book compete with the real-business-cycle model's technology shock in driving aggregate fluctuations.

Demand shocks likely play a key role in driving business cycles. However, in the standard new keynesian model, the monetary policy reaction to these shocks have a supply side effect. The change in real rate affects the marginal utility of consumption generating an income effect on labor supply.

New Keynesian Model I Sticky price model: I Pt = P¯ t is now exogenous, rather than endogenous I Extreme form of price stickiness: price level completely pre-determined I Replace labor demand curve with Pt = P¯ (which sets price), has to hire labor to meet demand at P¯ t rather than to maximize its value I Sticky wage model: I Wt = W¯ t is now exogenous, rather than endogenous.

The Canonical New-Keynesian Model Most New Keynesian macro takes as its starting point a three equation model. 1 New Keynesian Phillips curve ˇ t = E tˇ t+1 + x t + u t 2 Euler equation for output x t = E tx t+1 ˙(i t E tˇ t+1 r n) 3 And an equation describing how interest rate policy is set, usually described as an explicit interest rate rule.

It's based on the textbook of Jordi Galí. Money demand is ad-hoc. The central bank follows the Taylor rule. Author(s): Peter N. Ireland. Abstract: In a New Keynesian model, technology and cost-push shocks compete as terms that stochastically shift the Phillips curve. A version of this model, estimated via maximum likelihood, points to the cost-push shock as far more important than the technology shock in explaining the behavior of output, inflation, and interest rates in the postwar United States data.

A version of this model, estimated via maximum likelihood, points to the cost-push shock. In the New Keynesian model, preference, cost-push, and monetary shocks all compete with the real-business-cycle model's technology shock in driving aggregate : Peter N.

Ireland. Solving the model: monetary policy shock We have seen that the natural rate of interest evolves as: rn t = ˆ+ ˙Et y t n +1 (11) using the equation for natural output this can be written as: rn t= ˆ+ ˙ nya Et a +1 (12) Thus the natural rate evolution does not depend on monetary policy shocks.

If one assumes no technology shocks then: rn t = ˆ. Get this from a library. Technology shocks in the New Keynesian model. [Peter N Ireland; National Bureau of Economic Research.]. In the New Keynesian model, preference, cost-push, and monetary shocks all compete with the real business cycle model’s technology shock in driving aggregate fluctuations.

In the New Keynesian model, preference, cost-push, and monetary shocks all compete with the real business cycle model's technology shock in driving aggregate fluctuations.

Yet technology shocks also play a role in the New Keynesian model, where, for instance, an increase in pro-ductivity lowers each firm's marginal costs and thereby feeds into its optimal pricing decisions. The New Keynesian model therefore retains the idea that technology shocks can be quite important in shaping the dynamic behavior of key.

the transmission mecha-nism of monetary policy.These notes describe optimal monetary policy in the basic New Keynesian model.

2 Re-writing the Basic Model The basic NK model can be characterized by two main (log-linear) equations: the Phillips Curve it will raise the money supply in response to positive technology shocks. There is also a slight adjustment for lagged in.Abstract—In the New Keynesian model, preference, cost-push, and mon-etary shocks all compete with the real-business-cycle model’s technology shock in driving aggregate fluctuations.
