Forecasting Time-varying Densities of Inflation Rates: A Functional Autoregressive Approach∗
نویسندگان
چکیده
This paper utilizes the nonparametric functional autoregressive approach (FAR) to model the time-varying distribution of UK monthly inflation rates using disaggregated cross-sectional data. Our approach is free of any assumptions on the class or structure of the density functions themselves, or the number of dimensions in which the densities may vary. The “pseudo real time” in-sample forecasting evaluation results show that our proposed models track the realized event probabilities fairly closely. Furthermore, out-of-sample forecasting results suggest that the mean is projected to be stable at around 2.5%-2.6% over the period March 2008 February 2009 whilst the uncertainty bands stay between 1.5% and 4% over the 12-month forecast horizon. In addition, the probability of achieving the 2% inflation target is relatively low. JEL Classification: C14, C53, E31.

Modeling and Forecasting Iranian Inflation with Time Varying BVAR Models
This paper investigates the forecasting performance of different time-varying BVAR models for Iranian inflation. Forecast accuracy of a BVAR model with Litterman’s prior compared with a time-varying BVAR model (a version introduced by Doan et al., 1984); and a modified time-varying BVAR model, where the autoregressive coefficients are held constant and only the deterministic components are allo...

This paper has two aims. The first is forecasting inflation in Iran using Macroeconomic variables data in Iran (Inflation rate, liquidity, GDP, prices of imported goods and exchange rates) , and the second is comparing the performance of forecasting vector auto regression (VAR), Bayesian Vector-Autoregressive (BVAR), GARCH, time series and neural network models by which Iran's inflation is for...
متن کاملThe Effect of Macroeconomic Shocks on Inflation in Iran: A Vector Autoregressive Approach with Dynamic Parameters
Given the effects of inflation on the decline of household welfare and its impact on production and investment, identifying the factors affecting it in order to adjust inflation and achieve price stability is necessary. Therefore, using the TVP-FAVAR model, which differentiates the fluctuations in factors affecting inflation, we try to identify the effects of different shocks such as liquidity,...
متن کاملForecasting the distribution of multi-step inflation: do macro variables matter?
The evidence in the inflation forecasting literature suggests that simple time series models are typically hard to outperform in predicting the dynamics of the first moment, and that using information about indicators of economic activity does not lead to out-of-sample forecasting gains. While most of the earlier literature focused on the ability of leading indicators (via the Phillips Curve PC...
متن کاملForecasting irish inflation using ARIMA models
This paper outlines the practical steps which need to be undertaken to use autoregressive integrated moving average (ARIMA) time series models for forecasting Irish inflation. A framework for ARIMA forecasting is drawn up. It considers two alternative approaches to the issue of identifying ARIMA models the Box Jenkins approach and the objective penalty function methods. The emphasis is on forec...
