We make use of a data set that is both long span and high frequency to test for purchasing power parity while allowing for a structural shift in the volatility of the Mexico-US bilateral real exchange rate. The Kim, Leybourne and Newbold (2002) unit root test, robust to changes in the innovation...

We study the phenomenon of spurious regression between two random variables when the generating mechanism for individual series follows a stationary process around a trend with (possibly) multiple breaks in its level and slope. We develop relevant asymptotic theory and show that spurious...

This paper extends Gonzalo and Lee's (1998) results by studying the asymptotic and finite sample behavior of the Engle-Granger test for cointegration, under misspecification of the trend function in the form of neglected structural breaks. We allow breaks in level and slope of trend in both...

The literature on spurious regressions has found that the t-statistic for testing the null of no relationship between two independent variables diverges asymptotically under a wide variety of nonstationary data generating processes for the dependent and explanatory variables. This paper...

During the period 1950-2002 Africa has experienced a lower degree of economic development than Asia, due to several circumstances, and particularly to the low educational level of population in many African countries. In this article we present the estimation of some econometric models of...

The European Union lags behind the United States both in rates of employment and real wages. This study analyzes the relationship between wages, productivity and human capital in 5 European Union countries: France, Germany, Italy, Spain and the United Kingdom, in comparison with the USA. Firstly...

The main emphasis of labour policies in several EU countries seem to have been addressed during the period 1985-2005 to contain the increases of real wages, under the misleading belief that lower wages could lead the policies to get higher employment rates. We show that the main policies to...

We analyze the main positive effects of human capital on economic development, having into account direct and indirect relationships between the educational level of population and real Gdp per inhabitant through the production function, demographic evolution, industrial development, foreign...

We analyse the relationships between employment, population and regional development in Europe with a cross section sample, for year 2000, of 151 regions belonging to the 25 countries of EU after Enlargement of year 2004. Regional disparities in EU are higher than in the US, while the rate of...
