Researchers seldom find evidence of I(2) in exchange rates, prices, and other macroeconomics time series when they test the order of integration using univariate Dickey-Fuller tests. In contrast, when using the multivariate ML trace test they frequently find double unit roots in the data. The...

There are a number of econometrics tools to deal with the different types of situations in which cointegration can appear: I(1), I(2), seasonal, polyno- mial, etc. There are also different kinds of Vector Error Correction models related to these situations. The authors propose a unified...

The aim of this article is to examine how the dynamics of correlations between two emerging countries (Brazil and Mexico) and the US evolved from January 2003 to December 2013. The main contribution of this study is to explore whether the plunging stock market in the US, in the aftermath of...

By international comparison the productivity development of the overall economy in Germany has taken a serious hit after the reunification boom. Since then Germany has fallen behind not only in comparison to the USA and emerging-market nations like South Korea, but also in comparison to other EU...

Die gesamtwirtschaftliche Produktivitätsentwicklung in Deutschland ist nach dem Wiedervereinigungsboom im internationalen Vergleich deutlich eingebrochen. Nicht nur gegenüber den USA und Schwellenländern wie Südkorea, sondern auch im Vergleich zu anderen EU-Staaten fiel Deutschland seitdem...

The exchange markets and the exchange rates of Asia and Latin America are studied econometrically. Endogenous structural change and cointegration analyzes and impulse-response functions are used. The findings indicate that: 1) the long-term timing of the exchange markets is low; 2) there is no...

This paper examines how the size of the rolling window, and the frequency used in moving average (MA) trading strategies, affects financial performance when risk is measured. We use the MA rule for market timing, that is, for when to buy stocks and when to shift to the risk-free rate. The...

In this paper the authors investigate the statistical properties of some cryptocurrencies by using three layers of analysis: alpha-stable distributions, Metcalfe's law and the bubble behaviour through the LPPL modelling. The results show, in the medium to long-run, the validity of Metcalfe's law...

Existence of a cointegration relationship between two time series in the time domain imposes restrictions on the series zero‐frequency behaviour in terms of their squared coherence, phase and gain, in the frequency domain. I derive these restrictions by studying cross‐spectral properties of...

The purpose of the paper is to present the fundamental equation in tourism finance that connects tourism research to empirical finance and financial econometrics. The energy industry, which includes, oil, gas and bio-energy fuels, together with the tourism industry, are two of the most important...
