Forecasting U.S. Inflation: A Look Beyond the Conditional Mean
نویسندگان
چکیده
Most studies on U.S. inflation forecasting have focused on predicting the mean inflation using time series and Phillips Curve (PC) models. The findings indicate that using real economic indicators (such as unemployment or the output gap) improve out-of-sample forecasting performance during the late 1970s and the first half of the 1980s. But after 1985, PC based forecasts do not lead to forecasting gains vis-á-vis time series models (autoregressive and random walk models) when the latter models became a lot harder to outperform. Our study examines whether indicators of economic activity carry relevant information about the dynamics of higher moments of inflation, and hence help improve the accuracy of the distribution of inflation. We forecast (out-of-sample) the distribution of inflation for 6 and 12 months ahead for the period 1985:1 to 2007:12 and evaluate the performance of the various models in two sub-samples (1985:1 to 1995:12 and 1996:1 to 2007:12). Our results show that for the core inflation measures and PCE conditioning the dynamics of the predictive distribution on the leading indicators provides more accurate forecasts relative to time series models.

متن کاملReal-Time Inflation Forecasting in a Changing World
Abstract This paper revisits real-time forecasting of U.S. inflation based on Phillips curve-inspired linear regression models. Our innovation is to allow for both structural breaks in the regression parameters and the variance as well as uncertainty regarding which set of predictor variables one can include in these regressions (‘model uncertainty’). Structural breaks are described by occasion...
متن کاملA Multivariate Perspective for Modelling and Forecasting Inflation’s Conditional Mean and Variance
We test the importance of multivariate information for modelling and forecasting inflation’s conditional mean and variance. In the literature, the existence of inflation’s conditional heteroskedasticity has been debated for years, as it seemed to appear only in some datasets and for some lag lengths. This phenomenon might be due to the fact that inflation depends on a linear combination of econ...
متن کاملForecasting interest rates and inflation from bivariate time-series models: Can threshold cointegration models beat linear structures?
Using data from Germany, Japan, UK, and the U.S., we explore possible threshold cointegration in nominal shortand long-run interest rates with corresponding inflation rates. Traditional cointegration implies perfect mean reversion in real rates and hence confirms the Fisher hypothesis. Threshold cointegration accounts for the possibility that this mean reversion is active only conditional on ce...
متن کاملAre Macroeconomic Variables Useful for Forecasting the Distribution of U.S. Inflation?
Much of the inflation forecasting literature examines the ability of macroeconomic indicators to accurately predict mean inflation. For the period after 1984, existing empirical evidence largely suggests that the likelihood of accurately predicting inflation using macroeconomic indicators is no better than a random walk model. We expand the scope of inflation predictability by exploring whether...
