This paper analyses the asymptotic and finite sample implications of a mixed nonstationary behavior among the dependent and explanatory variables in a linear spurious regression model. We study the cases when the nonstationarity in the dependent variable is deterministic (stochastic), while the...

We study the phenomenon of spurious regression between two random variables,when the generating mechanism of individual series is assumed to follow a stationary process around a trend with (possibly) multiple breaks in the level and slope of trend. We develop the relevant asymptotic theory and...

We test the purchasing power parity hypothesis for the Mexican peso/US dollar real exchange rate using monthly data for 1969–2010. Results suggest that the real exchange rate reverts to a changing mean. These mean shifts can be explained by liberalization policies implemented during the 1980s...
