Is there a Phillips Curve in the US and the EU15 Countries? An empirical investigation

This paper studies the comovement between output and inflation in the EU15 countries. Following den Haan (2000), I use the correlations of VAR forecast errors at different horizons in order to analyze the output-inflation relationship. The empirical results show that eight countries display a significant positive comovement between output and inflation. Moreover, the empirical evidence suggests that a Phillips curve phenomenom is more likely to be detected in countries where inflation is more stable.

Inflation dynamics and the New Keynesian Phillips Curve: an identification robust econometric analysis

In this paper, we use identification-robust methods to assess the empirical adequacy of a New Keynesian Phillips Curve (NKPC) equation. We focus on the Gali and Gertler’s (1999) specification, on both U.S. and Canadian data. Two variants of the model are studied: one based on a rationalexpectations assumption, and a modification to the latter which consists in using survey data on inflation expectations. The results based on these two specifications exhibit sharp differences concerning: (i) identification difficulties, (ii) backward-looking behavior, and (ii) the frequency of price adjustments. Overall, we find that there is some support for the hybrid NKPC for the U.S., whereas the model is not suited to Canada. Our findings underscore the need for employing identificationrobust inference methods in the estimation of expectations-based dynamic macroeconomic relations.

The small open-economy New Keynesian Phillips Curve: empirical evidence and implied inflation dynamics

In this paper we apply GMM estimation to assess the relevance of domestic versus external determinants of CPI inflation dynamics in a sample of OECD countries typically classified as open economies. The analysis is based on a variant of the small open-economy New Keynesian Phillips Curve derived in Galí and Monacelli (Rev Econ Stud 72:707–734, 2005), where the novel feature is that expectations about fluctuations in the terms of trade enter explicitly. For most countries in our sample the expected relative change in the terms of trade emerges as the more relevant inflation driver than the contemporaneous domestic output gap.

Asymmetric output gap effects in Phillips Curve and mark-up pricing models: evidence for the US and the UK

A number of studies have found an asymmetric response of consumer price index inflation to the output gap in the US in simple Phillips curve models. We consider whether there are similar asymmetries in mark-up pricing models, that is, whether the mark-up over producers' costs also depends upon the sign of the (adjusted) output gap. The robustness of our findings to the price series is assessed, and also whether price-output responses in the UK are asymmetric.

Inflation dynamics and New Keynesian Phillips Curve in Australia

The New Keynesian Phillips Curve (NKPC) is a standard model in the analysis of inflation dynamics. For the Australian economy, this study establishes the empirical evidence that the NKPC can explain the process of inflation dynamics and the price-setting mechanism. The trade shocks, such as the real exchange rate and the terms of trade, play an important role in inflation dynamics.

The new Keynesian Phillips curve: an update on recent empirical advances

This paper presents a comprehensive review of the newly emerging literature on the New Keynesian Phillips Curve (NKPC). The theoretical predictions, econometric estimation techniques as well as the corresponding empirical evidence are discussed focusing on both the closed economy and the open economy versions of the NKPC. A number of important findings are reported about the ability of NKPC to explain the process of inflation dynamics. First, there is weak support for the open economy version of the NKPC to be able to track inflation dynamics if imported inputs are used in the production process. Second, the NKPC describes inflation dynamics across sectors if microeconomic and sectoral level data are used. Further, the survey data employed as a proxy for inflation measure in the newer studies provide enhanced support to the closed economy NKPC with the sign, size and statistical significance of coefficients in line with the theoretical predictions. We provide fresh empirical evidence to check the first finding from the review. The deep structural parameters for four different versions of the NKPC, the pure forward looking NKPC, the Gali and Monacelli's (2005) NKPC, the open economy NKPC and the open economy hybrid NKPC, are estimated for Australia, Canada, New Zealand and the United Kingdom. These estimated coefficients show some support that the specifications of open economy NKPC, which incorporate prices of imported goods as opposed to the terms of trade and real exchange rate, seems to be a better, however, weak indicator of the inflation dynamics. These findings may have important policy implications.

The new Keynesian Phillips curve in a small open economy: empirical evidence from Australia

This study estimates the new Keynesian Phillips curve (NKPC) ofGali and Monacelli for a small open economy using Australian data.Our detailed investigation hinges on estimating the structuralparameters in five different variants of the Gali–Monacelli NKPC,which relates the inflation process to terms of trade and the realexchange rate; the marginal cost and output gap as proxies for realeconomic activity and the hybrid version incorporating bothforward- and backward-looking inflation expectations. The analysisand extensive robustness checks overwhelmingly establish that theGali–Monacelli NKPC cannot explain the dynamics of inflation andis rejected by the Australian data.

The Long-Run Phillips Curve: A Structural VAR Investigation

Both cointegration methods, and non-cointegrated structural VARs identified based on either long-run restrictions, or a combination of long-run and sign restrictions, are used in order to explore the long-run trade-off between inflation and the unemployment rate in the post-WWII U.S., U.K., Euro area, Canada, and Australia. Overall, neither approach produces clear evidence of a non-vertical trade-off. The extent of uncertainty surrounding the estimates is however substantial, thus implying that a researcher holding alternative priors about what a reasonable slope of the long-run trade-off might be will likely not see her views falsified

Using a CGE Model to Identify the Policy Trade-Off between Unemployment and Inflation: The Efficient Phillips Curve

This paper provides a new reading of a classical economic relation: the short-run Phillips curve. Our point is that, when dealing with inflation and unemployment, policy-making can be understood as a multicriteria decisionmaking problem. Hence, we use so-called multiobjective programming in connection with a computable general equilibrium (CGE) model to determine the combinations of policy instruments that provide efficient combinations of inflation and unemployment. This approach results in an alternative version of the Phillips curve labelled as efficient Phillips curve. Our aim is to present an application of CGE models to a new area of research that can be especially useful when addressing policy exercises with real data. We apply our methodological proposal within a particular regional economy, Andalusia, in the south of Spain. This tool can give some keys for policy advice and policy implementation in the fight against unemployment and inflation.

Phillips-en kurba eta langabezi tasa naturala

[EU] Phillips-kurba-k langabezi eta inflazioaren arteko erlazio negatiboa erakusten du. Erlazio hau 1958. urtean aurkeztu zen lehen aldiz eta geroztik hainbat aldaketa, kritika eta eztabaida jasan ditu. Hala ere, honek ez du saihestu hainbat herrialdek politika ekonomiko desberdinak aurrera eraman izana erlazio honetan oinarrituta. Lan honetan Phillips-ek aipaturiko erlazioak jasandako aldaketa desberdinak azalduko ditugu, haren oinarriak eta eraldaketak aztertuz. Espainia eta Euskadiko Phillips kurben egoerak aztertuko ditugu eta Phillips-ek proposaturiko erlazioa betetzen den ala ez konprobatuko dugu.
