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,...

Over more than a decade, advertising rates per 1000 viewers, television consumption as well as the number of advertising spots have been steadily increasing. As a consequence, television has developed to the most important medium for the advertising industry and attracts a 40% share of German...

We analyse the decline in output volatility in Germany. A lower level of variance in an autoregressive model of output growth can be either due to a change in the structure of the economy (a change in the propagation mechanism) or a reduced error term variance (reduced impulses). In Germany the...

In the time domain, the observed cyclical behavior of the real wage hides a range of economic influences that give rise to cycles of differing lengths and strengths. This may serve to produce a distorted picture of wage cyclicality. Here, we deploy frequency domain methods that allow us to asses...

In the period of 2002–2006, observations of the unemployment development in municipalities situated in less favourable areas (hereafter LFA) of the micro-region of Strakonice and in other municipalities of the microregion outside of the LFA. The aim of the observations was to determine whether...

In this paper we revisit the methodological aspects of the issue of spurious cycles: using the well-established clinometric data, we apply an empirical strategy to identify spurious periodicities and cross-validate the results. The analysis of cyclical fluctuations involves numerous challenges,...

We present a multiscale analysis of the price dynamics of U.S. sector exchange-traded funds (ETFs). Our methodology features a multiscale noise-assisted approach, called the complementary ensemble empirical mode decomposition (CEEMD), that decomposes any financial time series into a number of...

In a classic article, Granger (1966) asserted that most economic time series measured in level have spectra that exhibit a smooth declining shape with considerable power at very low frequencies. There has been no systematic attempt to examine Granger,s assertion with international data. We...

In this paper, the sub-cycles in two economic activity measures are analyzed by using periodogram analyses. Our results from Turkish data suggest that industrial production and capacity utilization rate consist of various cycles including seasonal cycles. These series also have common cycles...
