In this paper we develop and estimate a behavioral model of inflation dynamics with monopolistic competition, staggered … naive. Fundamentalists are forward-looking in the sense that they believe in a present-value relationship between inflation … forecast future inflation. Agents are allowed to switch between these different forecasting strategies conditional on their …

A key application of long memory time series models concerns inflation. Long memory implies that shocks have a long … such level shifts are not unlikely for inflation, where the shifts may be caused by sudden oil price shocks, we examine … exaggerated. Our main findings are that apparent longmemory is quite resistant to level shifts, although for a few inflation rates …

The sum of squared intraday returns provides an unbiased and almost error-free measure of ex-post volatility. In this paper we develop a nonlinear Autoregressive Fractionally Integrated Moving Average (ARFIMA) model for realized volatility, which accommodates level shifts, day-of-the-week...

This paper develops a novel approach to modeling and forecasting realized volatility (RV) measures based on copula functions. Copula-based time series models can capture relevant characteristics of volatility such as nonlinear dynamics and long-memory type behavior in a flexible yet parsimonious...

The paper derives a Multivariate Asymmetric Long Memory conditional volatility model with Exogenous Variables (X), or the MALMX model, with dynamic conditional correlations, appropriate regularity conditions, and associated asymptotic theory. This enables checking of internal consistency and...

The paper develops a novel realized matrix-exponential stochastic volatility model of multivariate returns and realized covariances that incorporates asymmetry and long memory (hereafter the RMESV-ALM model). The matrix exponential transformation guarantees the positive-definiteness of the...

The paper develops a novel realized stochastic volatility model of asset returns and realized volatility that incorporates general asymmetry and long memory (hereafter the RSV-GALM model). The contribution of the paper ties in with Robert Basmann’s seminal work in terms of the estimation of...

This paper investigates the international spillovers of government debt and the associated risk of inflation within a … inflation at the cost of the funded country. In response to these conflicting interests about inflation, inflation risk may rise … with the level of debt in the PAYG country. Higher inflation risk harms both countries. Actually, in contrast to the debt …

In economics and finance, speculative bubbles take the form of locally explosive dynamics that eventually collapse. We propose a test for the presence of speculative bubbles in the context of mixed causal-noncausal autoregressive processes. The test exploits the fact that bubbles are...

This paper discusses identification, specification, estimation and forecasting for a general class of periodic unobserved components time series models with stochastic trend, seasonal and cycle components. Convenient state space formulations are introduced for exact maximum likelihood...
