Persistência inflacionária e curva de Phillips novo-keynesiana para o Brasil

Inflation persistence and new Keynesian Phillips curves for Brazil. In this paper is shown that sustainable inflation persistence has theoretical support not only due price indexation, but also because of micro-foundations based on assumptions of Simon's bounded rationality and because of persistent mark-up shocks. the new keynesian phillips curve, estimated for brazil for the period 2000/2008, and the partial coefficients of determination for moving sub-periods of 36 months identifies inflation persistence as the main determinant of inflation, with the capacity gap presenting larger importance only in the end of the sample period. Inflation persistence requires harder monetary policy when neither accommodation is acceptable nor complementary policies in order to reduce it, such as the minimization of indexation mechanisms and control of the market power, are adopted.

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.

Racionalidade imperfeita e inércia inflacionária : uma nova estimação da Curva de Phillips para o Brasil

O presente trabalho estima uma nova relação entre emprego e inflação para o Brasil, tendo como pano de fundo hipóteses propostas pelo arcabouço neo-keynesiano. Quatro hipóteses são testadas e sustentadas ao longo de todo o trabalho: i) os agentes não possuem racionalidade perfeita; ii) a imperfeição no processo de formação das expectativas dos agentes pode ser um fator determinante no componente inercial da inflação brasileira; iii) a inflação possui um componente inercial autônomo, que não depende de choques verificados em mercados isolados; e, iv) relações não-lineares entre inflação e desemprego são capazes de fornecer melhores explicações para o comportamento da economia nos últimos 12 anos. Enquanto as duas primeiras hipóteses são verificadas através de um modelo com mudanças markovianas, as duas últimas são testadas a partir da estimação de uma Curva de Phillips convexa, estimadas pelo Filtro de Kalman. Entretanto, mesmo fazendo uso destas estimativas, as funções de resposta da política monetária apresentam as mesmas propriedades de estimativas tradicionais para o Brasil.
