Hence, the unemployment rate fluctuates in a symmetric fashion around the NAIRU. 2 The Triangle Model of Inflation The NAIRU model is like its predecessor, the traditional Phillips curve, in the first place an inflation model. Since modeling inflation means modeling the pricesetting behavior of firms, it represents also the Keynesian view on the determination of aggregate supply. The events of the 1970s showed that the traditional Phillips curve was inadequate as an inflation model. ^^ The label "triangle" is meant to summarize the dependence of inflation on three basic determinants: inertia, demand, and supply (Gordon 1997: 14).

For a discussion of the role of the expectations-augmented Phillips curve in New Keynesian models see Roberts (1995). 1 Keynesian and Monetarist Explanations of Unemployment and Inflation 19 Figure 23: Business Cycle Fluctuations: The Monetarist View Output and potential output Time believe that prices are flexible enough to ensure that markets clear rapidly (Burda and Wyplosz 1997: 412). These differences are also apparent in the monetary transmission mechanism, since nominal wage and/or price rigidities play a central role in the Keynesian transmission mechanism of nominal impulses, but not in the monetarist transmission mechanism, where expectation errors are central.

Since monetarists believe that the risks of an activist monetary policy outweigh the benefits of reducing the volatility of output fluctuations, they recommend that policy should not try to offset minor disturbances to the economy (Friedman 1968: 14). Instead monetary policy should try to prevent monetary policy from becoming itself a source of economic disturbances and aim to provide a stable background for the economy by acting in a predictable way, thereby ensuring that the average level of prices will behave in a known way in the future (Friedman 1968: 13).
