This paper analyses house prices in Spain and Portugal over the last twenty years. In recent decades, housing prices have increased dramatically in the two countries; However, in 2007 the US subprime mortgage crisis broke out, which had worldwide influences, including Spain and Portugal. The...

This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

Using a fractional integration approach, we find that developing countries recover their economic growth faster than developed countries in response to a shock. The main finding is that longer civil conflicts are associated with a faster recovery process. To shed light on the channels, we...

This paper empirically examines the degree of persistence in four precious metal prices (i.e., gold, palladium, platinum, and silver) during the last four U.S. recessions. Unit root tests and fractional integration techniques suggest that gold still is the most prominent safe haven asset within...

This paper provides new evidence on the stochastic behaviour of the EPU (Economic Policy Uncertainty (EPU) index constructed by Baker et al. (2016) in six of the biggest economies (Canada, France, Japan, US, Ireland, and Sweden) over the period from January 1985 to October 2019. In particular,...

This paper examines the long-run dynamics and the cyclical structure of the US stock market using fractional integration techniques, specifically a version of the tests of Robinson (1994a) which allows for unit (or fractional) roots both at the zero (long-run) and at the cyclical frequencies. We...

This paper examines the PPP hypothesis analysing the behaviour of the real exchange rates vis-à-vis the US dollar for four major currencies (namely, the Canadian dollar, the euro, the Japanese yen and the British pound). An innovative approach based on fractional integration in a multivariate...

This paper analyses the long-memory properties of a high-frequency financial time series dataset. It focuses on temporal aggregation and other features of the data, and how they might affect the degree of dependence of the series. Fractional integration or I(d) models are estimated with a...
