Physically, evaporative demand is driven by net radiation (Rn), vapour pressure (ea), wind speed (u2), and air temperature (Ta), each of which changes over time. By analyzing temporal variations in reference evapotranspiration (ET0), improved understanding of the impacts of climate change on...

The aim of this article is to provide additional evidence on the fulfilment of the Purchasing Power Parity (PPP) hypothesis in the so-called Mediterranean countries. In order to test for the empirical validity of such a hypothesis, we have applied two types of unit root tests. The first group is...

This study applies a group of unit root and stationarity tests to study the hypothesis of Purchasing Power Parity in ten Mediterranean countries. The real effective exchange rate with the European Union turns out to be stationary for five of the countries analysed, once the presence of...

Countries in the Asia and Pacific region have shown many macroeconomic similarities such as current account surpluses, exchange rate appreciation, export-oriented economies, growth success, etc. This paper argues that there may be one more macroeconomic feature to add to the list: strong tax...

This paper seeks to shed light on possible changes in the government debt dynamics for the first 12 euro area countries. Structural breaks are present around the global financial crisis for most countries, but not for Germany and France, the two core countries in the euro area. The properties of...

This paper examines the interaction between non-linear deterministic trends and long run dependence by means of employing Chebyshev time polynomials and assuming that the detrended series displays long memory with the pole or singularity in the spectrum occurring at one or more possibly non-zero...

The role the real exchange rate plays in determining current account balances has gathered momentum as East and Southeast Asian countries have seen increasingly positive current account balances. This paper analyses the evolution of current accounts in the region. A cointegrating relationship...

In this paper we analyse real convergence in GDP per worker in the EU member states. The aim is to test whether there is evidence of club convergence in the EU, i.e. divergence in GDP per worker. Evidence in favour of cluster or club convergence may be an indication of significant productivity...

The aim of this article is to develop a unit root test that takes into account two sources of nonlinearites in data, i.e. asymmetric speed of mean reversion and structural changes. The asymmetric speed of mean reversion is modelled by means of a exponential smooth transition autoregression...
