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 hypothesis in the so-called Mediterranean countries. In order to test for the empirical validity of such hypothesis, we have applied two types of unit root tests. The first group is due to...

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...

In this paper we provide an insight into the inflation dynamics in a panel of Central and Eastern European countries. These countries are selected because of their increasing importance in the EU and their likely increased future importance in monetary policy decisions inside the euro area. By...

In this paper we aim at testing the inflation persistence hypothesis as well as modelling (using logistic smooth transition autoregressive, LSTAR, models) the long run behaviour of inflation rates in a pool of African countries. In order to do so, we rely on unit root tests applied to nonlinear...

This paper tests the view that the relation between unemployment and entrepreneurship is dynamic and possibly nonlinear. It performs Granger-causality tests and STAR-EXT estimation to assess the causality direction and the nonlinear nature of the relation for a set of OECD countries. The results...

Unit root tests are the starting point of most empirical time series research. This paper analyses the order of integration of oil prices taking into account the possibilities of nonlinearities in the deterministic components. Using an aggregate index for the price of oil, and applying Bierens...

This paper presents a cyclical model for unemployment and entrepreneurship. The estimated periodicity of the cycles for the US, the UK, Spain and Ireland is between 5 and 10 years, and the orders of integration are smaller (greater) than 1 if the underlying disturbances are autocorrelated (white...

The aim of this paper is to provide additional evidence about the order of integration of constant price GDP per capita in a selection of countries. It does so by taking into account the possibility of non-linear deterministic trends and of asymmetric adjustment towards equilibrium. We find...
