Does Modern Econometrics replicate the Phillips Curve?
No full textThis paper reexamines the existence of a long-run relationship between wages and unemployment in the U.K., with data over the period 1860-1913 used by A.W. Phillips to derive the well-known Phillips Curve. Using Johansen's maximum likelihood method of testing for cointegration, a long-run inverse relationship is indeed depicted between the rate of inflation and the unemployment rate. However, the main impact of deviations from this long-run equilibrium is on the unemployment rate rather than the rate of inflation.Phillips Curve; long-run equilibrium; cointegration
Monetary Union Stability: The Economics of the Phillips Curve: Formation of Inflation Expectations versus Incorporation of Inflation Expectations
No full textThis paper examines the theory of the Phillips curve, focusing on the distinction between "formation" of inflation expectations and "incorporation" of inflation expectations. Phillips curve theory has largely focused on the former. Explaining the Phillips curve by reference to expectation formation keeps Phillips curve theory in the policy orbit of natural rate thinking where there is no welfare justification for higher inflation even if there is a permanent inflation - unemployment trade-off. Explaining the Phillips curve by reference to incorporation of inflation expectations breaks that orbit and provides a welfare economics rationale for Keynesian activist policies that reduce unemployment at the cost of higher inflation.Phillips curve, formation of inflation expectations, incorporation of inflation expectations, backward bending Phillips curve.
The new Keynesian Phillips curve: empirical results for Luxembourg
No full textThe New Keynesian Phillips curve (NPC) differs from the conventional expectations-augmented Phillips curve in that it is forward-looking and links inflation to a measure of marginal cost instead of unemployment or the output gap. More fundamentally, the NPC is derived from New Keynesian models that combine nominal rigidities with individual optimising behaviour and model-consistent (rational) expectations. Because the NPC is grounded in micro-theory (unlike the conventional expectations-augmented Phillips curve), it is robust to some forms of the Lucas critique and may serve to analyse the impact structural changes such as increased price flexibility may have on inflation. New Keynesian Phillips curve estimates for Luxembourg using the Galí and Gertler (1999) hybrid form suggest that firms change prices often but tend to use backward-looking rules-of-thumb instead of resetting prices optimally using forward-looking expectations. In terms of policy implications, although the results suggest prices in Luxembourg are relatively flexible, the prevalence of backward-looking price setting implies greater inflation persistence and a higher sacrifice ratio attached to disinflationary monetary policy. From the perspective of individual firms, backward-looking price setting may be a rational response in a very small open economy because of its vulnerability to external shocks. Small size and openness plausibly imply higher costs of collecting information and lower benefits from optimal price setting.
The Nonlinearity of the Phillips Curve and European Monetary Policy
No full textThis paper deals with the question of whether the euro area Phillips curve is nonlinear. There has recently been a great deal of discussion and studies concerning the same question in the US context. The data set includes most of the euro area countries, namely Austria, Germany, Finland, France, Italy, the Netherlands and Spain. Estimation is made both with pooled data and with country-specific models. The results give a clear indication of nonlinearity of the Phillips curve in many euro countries. The curve is asymmetric in the sense that, with a positive output gap (actual output is greater than potential output), its impact on inflation is positive, but, with a negative output gap, the deflationary impact is very small and not significant as a rule. The Phillips curve has been especially asymmetric in Germany, Finland, Italy, the Netherlands and Spain. An important result of the study is the strong negative influence of inflation uncertainty on GDP in the euro countries during the estimation period, 1976-1997. This effect was very strong in pooled data but also at country level. This result is new in the sense that a Lucas-type supply function and especially nonlinear versions of it have not been estimated very often. Another interesting result is that Phillips curves can be estimated with good success using OECD Secretariat forecast data for inflation expectations. A very important result for monetary policy are the large differences between countries as regards the slope and shape of the Phillips curve. The policy implication of nonlinearity is clear. The costs of unduly expansive monetary policy could be high in the euro area in the medium term. Nonlinearity also means that inflation pressure in the euro area is dependent not only on the average demand situation but also on how economic activity is distributed across the region.Phillips curve; nonlinearity; monetary policy; uncertainty; euro area country differences
Letter from Hubert Phillips to American Civil Liberties Union of Northern California, August 4, 1942
No full textLetter from Hubert Phillips to American Civil Liberties Union of Northern California, enclosing checks for $57 from F. C. Kellogg, Arthur E. Geschke, Claus Bertelsen, and Hubert Phillips. The letter states that the checks represent "the contributions of about twenty-five people made at a dinner held here recently to consider the phases of the status of citizens of Japanese ancestry and is to be applied specifically to helping prosecute the case of Miss Mitsuye Endo. Mr. F. C. Kellogg of the Fowler High School faculty was the author of the idea and deserves the credit for raising the enclosed contribution."The ACLU-Northern California case file records contain legal documents and correspondence pertaining to the case Ex parte Mitsuye Endo (1944), in which the United States Supreme court unanimously ruled that the federal government could not indefinitely detain United States citizens who were loyal to the government. Files include documents related to the Gordon Hirabayashi Supreme Court case Hirabayashi v. United States
Identifying the New Keynesian Phillips Curve
No full textPhillips curves are central to discussions of inflation dynamics and monetary policy. New Keynesian Phillips curves describe how past inflation, expected future inflation, and a measure of real marginal cost or an output gap drive the current inflation rate. This paper studies the (potential) weak identification of these curves under GMM and traces this syndrome to a lack of persistence in either exogenous variables or shocks. We employ analytic methods to understand the identification problem in several statistical environments: under strict exogeneity, in a vector autoregression, and in the canonical three-equation, New Keynesian model. Given U.S., U.K., and Canadian data, we revisit the empirical evidence and construct tests and confidence intervals based on exact and pivotal Anderson-Rubin statistics that are robust to weak identification. These tests find little evidence of forward-looking inflation dynamics.Phillips curve, Keynesian, identification, inflation

Evolving Phillips trade-off
No full textWe characterise the evolution of the U.S. unemployment-inflation trade-off since the late XIX century era via a Bayesian time-varying parameters structural VAR. The Great Inflation episode appears as historically unique along several dimensions. In particular, the shape of the ‘Phillips loop’–which is defined in terms of the impulse-response functions of inflation and unemployment’s deviations from equilibrium–was, during those years, clearly out of line with respect to the rest of the sample period for all structural innovations except money demand shocks. During the Great Depression, on the other hand, the Phillips trade-off did not exhibit any peculiar qualitative feature, so that, when seen through these lenses, the 1930s only stand out because of the sheer size of the macroeconomic fluctuation. The historical evolution of the Phillips trade-off exhibits virtually no connection with the evolution of the extent of trade openness of the U.S. economy. Although, by itself, this does not rule out a possible impact of globalisation on the slope of the trade-off in recent years, it clearly suggests that, historically, the evolution of the trade-off has been dominated by factors other than trade openness.
