This paper proposes a novel and flexible framework to estimate autoregressive models with time-varying parameters. Our setup nests various adaptive algorithms that are commonly used in the macroeconometric literature, such as learning-expectations and forgetting-factor algorithms. These are...

This study examines the effectiveness of using webscraped data to predict price developments in the Austrian food retail sector. We calculate monthly nowcasts of price changes based on daily price data collected by the OeNB since mid-2020, using Eurostat methodology for price index calculation,...

This paper studies inflation persistence with time-varying coefficient autoregressions for twelve central European countries,in comparison with the United States and the euro area. Inflation persistence tends to be higher in times of high inflation. Since the oil price shocks, inflation...

Although the properties of the ARCH(∞) model are well investigated, the existence of long memory FIGARCH and IARCH solution was not established in the literature. These two popular ARCH type models which are widely used in applied literature, were causing theoretical controversy because of the...

We consider changes in the degree of persistence of a process when the degree of persistence is characterized as the order of integration of a strongly dependent process. To avoid the risk of incorrectly specifing the data generating process we employ local Whittle estimates which uses only...

The presence of long memory in Realized Volatility (RV) is a widespread stylized fact. The origins of long memory in RV have been attributed to jumps, structural breaks, non-linearities, or pure long memory. An important development has been the Heterogeneous Autoregressive (HAR) model and its...

This study analyses India's inflation using the Phillips curve theory. To estimate an open-economy Phillips curve, we need three variables: (1) inflation (2) the output gap and (3) the real effective exchange rate. In India, the incorrect measurement of variables causes much difficulty in...

The purpose of the paper is to introduce the framework for decomposing the forecast of headline inflation, obtained by macroeconomic model of NBRM for monetary policy analysis and medium term projections (MAKPAM), into its components: food, energy and core inflation. The model for inflation...

This paper conducts a structural analysis of inflation persistence in the United Kingdom between 1965-2009. I allow for the possibility of shifts in the U.K. economy by estimating open-economy dynamic stochastic general equilibrium models in which parameters of a Taylor-type monetary policy...

In this paper, we investigate the effects of monetary policy concerning the inflation rates specific for each income group of households. We find that the prices specific for high-income households are generally more rigid and less volatile compared to the prices specific for middle and...
