Abstract: Accurate forecasts of the inflation rate are essential for tracking the economic streaming. In the early inflation forecasting research, focus was directed toward developing regression-based methods. Despite their performance, several lines of evidence consider that using them is prohibitive due to the variable nature of the inflation series. Henceforth, a number of empirical-data based tools have been put forward. Amongst these, ANN models have been shown to yield satisfactory results. This has motivated several researchers to question the best way for efficient inflation forecasting and accordingly, conduct several comparative studies on the relative performances between allied methods. In our sense, it is more judicious to make use of the advantages provided by each forecasting approach rather than exclusively choose one between them. In this paper, we develop a combined forecasting model which integrates time-series and ANN and test its performance in forecasting inflation by means of an empirical comparative study.
