This paper examines the comovement of the stock market and of real activity in Germany before World War I under the efficient market hypothesis. We employ multivariate spectral analysis to compare rivaling national product estimates to stock market behaviour in the frequency domain. Close...

This paper introduces a nonparametric Granger-causality test for covariance stationary linear processes under, possibly, the presence of long-range dependence. We show that the test is consistent and has power against contiguous alternatives converging to the parametric rate T-½. Since the test...

We conduct Monte Carlo experiments to examine whether the Hansen and Jagannathan (1991) bound is a useful device for evaluating asset pricing models. Specifically, we use recently developed statistical tests, which are based on a 'distance' between the model and the Hansen-Jagannathan bound, to...

This paper tests for nonlinearity in EMS exchange rates using the bispectrum. The early experience of the ERM witnessed numerous realignments. We find that exchange rates follow a linear process over the period 1979-1987, consistent with the predictions of the realignment target zone model,...

Many empirical studies find that financial variables possess a predictive power over real economic activity. To examine this relationship, we adopt two time-series techniques: spectral analysis and a newly developed method, wavelet analysis. The major innovation of this paper is to apply wavelet...

The comparison and classification of time series is an important issue in practical time series analysis. For these purposes, various methods have been proposed in the literature, but all have shortcomings, especially when the observed time series have different sample sizes. In this paper, we...

We cast some classes of fitness landscapes as problems in spectral analysis on various Cayley graphs. In particular, landscapes derived from RNA folding are realized on Hamming graphs and analyzed in terms of Walsh transforms; assignment problems are interpreted as functions on the symmetric...

Class specific mortality in 17th and 18th Century Vienna shows a cyclical pattern which is related to grain price cycles in the 5-10 years range. This relationship is not stable over time. Applying spectral analysis based on time-varying VARs, it can be shown that at the beginning of the...

A spectral analysis of the Australian time series for the investment and savings ratio on monthly data over the period finds that the investment ratio is subject to a cycle of 6 months duration while the savings ratio series is concentrated on a longer swing of 4 to 6 years. The implications for...

Purpose – The purpose of this paper is to examine whether the banking crisis in the USA and Western Europe that began in August 2007 precipitated a change in the relationship between the currencies of the Baltic States and the Euro, such that it could be described as shift contagion. The paper...
