The first part of this website contains the required readings for my part of the course. The Discounted Euler Equation: A Note Neoclassical synthesis The short-run Phillips curve, illustrated in the figure titled "The Phillips Curve", shows that the relationship between the inflation rate () and unemployment is negative. This is the basic analytical structure of Michael Woodford’s book Interest and Prices published in 2003 and, for example, of the widely cited paper ‘The New Keynesian Science of … tancockroach82. Topic 7: The New-Keynesian Phillips Curve 10: Fiscal Policy 4. Being Keynesian in the short run and neoclassical in the long run, neoclassical synthesis … The Keynesian zone occurs at the left of the SRAS curve where it is fairly flat, so movements in AD will affect output, but have little effect on the price level. Say’s law says supply creates its own demand. Changes in aggregate demand have no effect on real GDP and employment, only on the price level. Singleton (1982), “Generalized Instrumental Variables Estimation of Nonlinear Rational Expectations Models”, Econometrica, 50, 1269-86, … The Phillips curve models the inverse trade-off between inflation and unemployment. According to the theory, the higher the unemployment rate, which creates labor slack and downward wage pressure, the lower the inflation rate, and vice versa. Prior to the 1970s it was viewed as an ironclad rule. (1999), however, without giving a full derivation of the IS curve and the Phillips curve. A Simple Model with a Taylor Rule Consider the basic New Keynesian model described by the equilibrium con-ditions: Phillips curve: ˇ t = E tfˇ t+1g+ ey t IS equation: ey t = E tfye t+1g 1 ˙ (r t E tfˇ t+1g rr tg Policy rule r t = ˚ ˇ ˇ t They are a ected by aggregated TFP. Using this • Dynamic IS curve x˙ (t)=i(t) ⇡(t) r(t) • New Keynesian Phillips curve ⇡˙ (t)=⇢⇡(t) x(t) • Interest rate rule, say i(t)=r(t)+⇡⇡(t), • Unique equilibrium if ⇡ > 1 but multiple equilibria if ⇡ < 1 16 Nominal Rigidities. The textbook three equation New Keynesian (NK) model (see, e.g.,Woodford2003orGal 2008) has enormous in uence in both policy circles and among academic researchers due to its elegance and tractability. We have already had forward-looking households and firm making savings and investment decisions as well as central bank forecasting and decision-making. Course.

Phillips Curve • New Keynesian Phillips curve: • The inflation rate is determined by – the inflation expectations E t[π t+1]: firms, that can change their prices in period t, take into account expected future price changes, as they possibly are not allowed to adjust next period (and thereafter), – the output gap x This is included in Walsh (2003), page 232 onwards, whose presentation we adopt as well. For Monday April 22: We finished Woodford (2011). In economics, the Phillips curve is a historical inverse relationship between the rate of unemployment and the rate of inflation in an economy.

Then the resulting price setting policy is used in the derivation of the New Keynesian Phillips curve. † References in the notes refer to articles given on the reading list. ; The "Modern IS-LM Model", the "Modern AS-AD Model". This relationship helps to explain the adage "there is no good news in economics."

" The FOC from the previous problem, combined with the aggregate price equation and taken in logs gives rise to the New Keynesian Phillips Curve (NKPC): Finally, to close the model, we suppose that monetary authority controls the nominal interest rates and is concerned by both price and GDP growths. The first version is the New Keynesian Phillips Curve, which in addition to slack includes short-run inflation expectations, but has no lagged inflation in it. Solving the Euler equation forward yields C^ t … "The formation of expectations, inflation, and the phillips curve." Lecture 12 The Phillips Curve.

This section provides recitation notes as supplements to the lecture notes. The New Keynesian Phillips’ Curve is derived from the Calvo model [1983] which combines staggered price-setting by imperfectly competitive firms. We can then let P_ and Y be The former refers to such events like the 1973 oil crisis , while the latter refers to the price/wage spiral and inflationary expectations implying that inflation is the new normal.

As Sargent (1987, p. 438) puts it: “The Phillips curve, expressing the rate of change of wages as a function of unemployment, fit very well into the Keynesian model because it seemed to provide a convenient device for making wages endogenous to the Keynesian model over time, although still fixed at a moment of time.”. The standard version of the New Keynesian Model is discussed in detail by Clarida et al. I follow Gali’s (2008) book as closely as possible.
