TLDR
In this article, the authors applied factor models proposed by Stock and Watson (1999) and VAR and ARIMA models to generate 12-month out of sample forecasts of Austrian HICP inflation and its subindices processed food, unprocessed food, energy, industrial goods and services price inflation.Abstract:
In this paper we apply factor models proposed by Stock and Watson (1999) and VAR and ARIMA models to generate 12-month out of sample forecasts of Austrian HICP inflation and its subindices processed food, unprocessed food, energy, industrial goods and services price inflation. A sequential forecast model selection procedure tailored to this specific task is applied. It turns out that factor models possess the highest predictive accuracy for several subindices and that predictive accuracy can be further improved by combining the information contained in factor and VAR models for some indices. With respect to forecasting HICP inflation, our analysis suggests to favor the aggregation of subindices forecasts. Furthermore, the subindices forecasts are used as a tool to give a more detailed picture of the determinants of HICP inflation from both an ex-ante and ex-post perspective.read more

Combining Disaggregate Forecasts or Combining Disaggregate Information to Forecast an Aggregate
David F. Hendry,Kirstin Hubrich +1 more
TL;DR: This paper proposed adding disaggregate variables, instead of combining forecasts of those disaggregates or forecasting by a univariate aggregate model, to forecast an aggregate, and showed the effects of changing coefficients, mis-specification, estimation uncertainty and mis-measurement error.

Comparing the New Keynesian Phillips Curve with time series models to forecast inflation
TL;DR: In this paper, the authors proposed a method of forecasting inflation based on the present-value formulation of the hybrid New Keynesian Phillips Curve, and compared it with forecasts generated from a traditional Phillips Curve and time series models at different forecast horizons.

Comparing Predictive Accuracy
TL;DR: The authors describes the advantages of these studies and suggests how they can be improved and also provides aids in judging the validity of inferences they draw, such as multiple treatment and comparison groups and multiple pre- or post-intervention observations.

Comparing Predictive Accuracy
TL;DR: In this article, explicit tests of the null hypothesis of no difference in the accuracy of two competing forecasts are proposed and evaluated, and asymptotic and exact finite-sample tests are proposed, evaluated and illustrated.

Determining the Number of Factors in Approximate Factor Models
Jushan Bai,Serena Ng +1 more
TL;DR: In this article, the convergence rate for the factor estimates that will allow for consistent estimation of the number of factors is established, and some panel criteria are proposed to obtain the convergence rates.

TL;DR: In this paper, the authors developed some econometric theory for factor models of large dimensions and proposed some panel C(p) criteria and showed that the number of factors can be consistently estimated using the criteria.
