"Copper Miner" Sculpture by R. Phillips Sanderson
No full textTo portray “beauty, toil and simplicity” was the goal of artist, R. Phillips Sanderson, when he designed the "Copper Miner." Sanderson had moved to Bisbee during the Depression and worked as a commercial artist. He was paid $30.00 per month by the Federal Emergency Relief Administration during the six months it took to complete the statue. Bisbee native, Lee Petrovitch, posed for the artist. The statue was cast in concrete and covered (metalized) with a thin layer of copper. The statue was dedicated to all of the miners who had worked in Bisbee mines

Wage and Price Phillips Curves
No full textIn this paper we introduce a small Keynesian model of economic growth which is centered around two advanced types of Phillips curves, one for money wages and one for prices, both being augmented by perfect myopic foresight and supplemented by a measure of the medium-term inflationary climate updated in an adaptive fashion. The model contains two potentially destabilizing feedback chains, the so-called Mundell and Rose-effects. We estimate parsimonious and congruent Phillips curves for money wages and prices in the US over the past five decades. Using the parameters of the empirical Phillips curves, we show that the growth path of the private sector of the model economy is likely to be surrounded by centrifugal forces. Convergence to this growth path can be generated in two ways: a Blanchard-Katz-type error-correction mechanism in the money-wage Phillips curve or a modified Taylor rule that is augmented by a term, which transmits increases in the wage share (real unit labor costs) to increases in the nominal rate of interest. Thus the model is characterized by local instability of the wage-price spiral, which however can be tamed by appropriate wage or monetary policies. Our empirical analysis finds the error-correction mechanism being ineffective in both Phillips curves suggesting that the stability of the post-war US macroeconomy originates from the stabilizing role of monetary policy.Phillips curves, Mundell effect, Rose effect, monetary policy, Taylor rule, inflation, unemployment, instability
The Phillips Curve in Australia
No full textIn this paper we discuss the development of Phillips curves in Australia over the forty years since Phillips first estimated one using Australian data. We examine the central issues faced by researchers estimating Australian Phillips curves. These include the distinction between the short and long-run trade-offs between inflation and unemployment, and the changing level of the non-accelerating inflation rate of unemployment (NAIRU), particularly in the 1970s. We estimate Phillips curves for prices and unit labour costs in Australia over the past three decades. These Phillips curves allow the NAIRU to change through time, and include a role for import prices and ‘speed-limit’ effects. The paper concludes by presenting an extended discussion of the changing role of the Phillips curve in the intellectual framework used to analyse inflation within the Reserve Bank of Australia over the past three decades.Phillips curve; inflation; unemployment; monetary policy
The South African Phillips Curve: How Applicable is the Gordon Model?
No full textIs there a Phillips curve relationship present in South Africa and if so, what form does it take? Traditionally the way to estimate the Phillips curve is merely to regress the change in the price level on a measure of the output gap (or the deviation of actual unemployment from the NAIRU). However, Gordon (1990:481-5) has argued that estimating the Phillips curve in this manner biases the estimated results. Instead, Gordon (1997; 1989) puts forward his so-called triangular model that controls for inertia effects, output level effects and rates-of-change (in output) effects. He applies the model to several European countries, the US and Japan and finds meaningful results. The question this paper poses is whether or not the triangular model also applies to South Africa. In estimating the Phillips curve for South Africa the paper also experiments with four versions of the output gap, based on four different methods to estimate long run output, including the standard Hodrick-Prescott (HP) filter and the production function approach. There are several variants of the Phillips curve. The first, as estimated by Phillips (1958) himself, measures the relationship between wage inflation and unemployment. However, other versions consider the relationship between price inflation and unemployment or price inflation and output. This paper focuses on the latter, given the absence of quarterly unemployment data in South Africa, as well as the lack of a reliable and sufficiently long unemployment time series. The paper first presents an overview of literature on the Phillips curve and its estimation for South Africa and other countries. This is followed by the second section that considers the model to be estimated, the data as well as the discussion of the alternative measures of the output gap. The third section presents the estimated results followed by section four that contains the conclusion and a discussion of the policy implications.
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
Is the Phillips Curve of Germany Spurious?
No full textA simple plot of seasonal adjusted quarterly data between the change of nominal wage rates and the unemployment rate for the German economy shows a picture similar to that by which Phillips was inspired to his famous discovery, that there is a long-term tendency of a negative, non-linear relationship coupled with minor deviations from this tendency, which form so-called loops. At first sight, the Phillips Curve of Germany comprises clusters of data points and movements between these clusters. In spite of the striking differences of these phenomena, a model with one regression equation is sufficient to explain the loops, the movements between the loops and the long-term tendency of the German Phillips Curve. It might well be that the German Phillips Curve and the corresponding regressions are spurious, but an allegedly missing co-integration of wage rate changes and unemployment rate is not the argument that could be drawn on to sustain this scepticism. On the contrary, both variables are co-integrated. To get a more detailed insight into the relationship, the two variables are split into a trend and a cyclical component by the help of the HP-filter. The results of regression analyses applied to the separated components support Phillips’ hypothesis of a negative relationship between wage rate changes and the unemployment rate.Wages, Unemployment, Phillips Curve
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.
