В статье рассмотрены методологические вопросы построения экономико-математических динамических моделей прогнозирования производительности труда рабочих....

In this paper, we suggest a different dynamic measure of comovement which is unlike previous studies allowing to test instability in comovement between two non stationary economic time series. We use the frequency approach, which is based on evolutionary spectral analysis, to estimate the...

In his celebrated 1966 Econometrica article, Granger first hypothesized that there is a ‘typical’ spectral shape for an economic variable. This ‘typical’ shape implies decreasing levels of energy as frequency increases, which in turn implies an extremely long cycle in economic...

Many methods are available to analyze rank ordered data. We used a spectral density analysis to identify most preferred options of Formosan Subterranean Termites (FST) control as ranked by Louisiana homeowners. Respondents are asked to rank four termite control methods form the most preferred...

We decompose the Backus-Smith [1993] statistic --- a low or negative correlation between relative consumption and the real exchange rate at odds with a high degree of international risk sharing --- in its dynamic components at different frequencies. Using multivariate spectral analysis...

This paper attempts to assess the level of synchronization between the business cycles of Poland’s regions and those of the country as a whole. The measure of economic activity was an index of total industrial output sold, recorded monthly from January 1999 to December 2008, adjusted for...

We decompose the Backus-Smith [1993] statistic -- a low or negative correlation between relative consumption and the real exchange rate at odds with a high degree of international risk sharing -- in its dynamic components at di¤erent frequencies. Using multivariate spectral analysis techniques...

The results of a Monte Carlo research for the Hansen Lc, MeanF and SupF stability tests for long-run relationships are reported. The tests are related to the Phillips-Hansen and Hansen semiparametric methods, which involve kernel density estimation of the long-run covariance matrix. We compare...

In this paper we present an alternative method for the spectral analysis of a strictly stationary time series {Yt}t2Z. We define a “new” spectrum as the Fourier transform of the differences between copulas of the pairs (Yt, Yt−k) and the independence copula. This object is called copula...
