Granger (1966) describes how the spectral shape of an economic variable concentrates spectral mass at low frequencies, declining smoothly as frequency increases. Despite a discussion about how to assess robustness of his results, the empirical exercise focused on the evidence obtained from a...

This paper examines the issue of international synchronization of cycles. Using spectral methods we analyze the pattern of co-movement (coherences) of growth rate cycles between countries across frequency bands and overtime. We also examine the lead-lag structure (phase shifts) of country cycles...

An effective and easy-to-implement frequency filter is designed by convolving a Hamming window with the ideal rectangular filter response function. Three other filters (Hodrick-Prescott, Baxter-King, and Christiano-Fitzgerald) are critically reviewed. The behavior of the Hamming-windowed filter...

The last ten years have witnessed an increasing interest of the econometrics community in spectral theory. In fact, decomposing the series evolution in periodic contributions allows a more insightful view of its structure and on its cyclical behavior at different time scales. In this paper I...

An effective and easy-to-implement frequency filter is proposed, obtained by convolving a raised-cosine window with the ideal rectangular filter response function. Three other filters, Hodrick–Prescott, Baxter–King, and Christiano–Fitzgerald, are thoroughly reviewed. A bandpass version of...

Ce papier présente des méthodes courantes d’extraction du cycle :les filtres classiques de Hodrick-Prescott, Baxter-King et Christiano-Fitzgerald, puis les filtres numériques de Butterworth, de Hamming et de Hanning, enfin la modélisation tendance-cycle à composantes inobservables. Ces...

In this paper, we use the Markov chain censoring technique to study infinite state Markov chains whose transition matrices possess block-repeating entries. We demonstrate that a number of important probabilistic measures are invariant under censoring. Informally speaking, these measures involve...

This paper employs a panel vector autoregressive model (PVAR) to study the dynamics of the overall exchange rate volatility. PVAR estimation results, based on panel data for 29 economies, are used in simulating impulse response functions. Since economic shocks may affect high-frequency and...

This research uses spectral methodology to study how the volatility of spot exchange rate misalignments changed as a result of signing of the Plaza Accord and introduction of the Euro. We study the deviations of Canadian Dollar/US Dollar, Japanese Yen/US Dollar and US Dollar/British Pound spot...

This paper presents a theorical framework to model the evolution of a portfolio whose weights vary over time. Such a portfolio is called a dynamic portfolio. In a first step, considering a given investment policy, we define the set of the investable portfolios. Then, considering portfolio...
