The small sample size properties of three frequently used cointegration tests when a system has been misspecified are investigated. Specifically, the misspecification consists of one relevant variable being omitted from a system with one cointegrating vector. A Monte Carlo study shows that the...

This study tests for the presence of unit roots in four US macroeconomic time series using panel unit root tests. The Im, Pesaran and Shin (Journal of Econometrics, 115, pp. 53-74, 2003) test, the Multivariate Augmented Dickey-Fuller test (Taylor and Sarno, Journal of International Economics,...

Theory predicts that life cycle saving and consumption behaviour could cause real exchange rate variations as the age structure varies. Time series regressions show that the Swedish demographic structure has significant explanatory power on the real exchange rate during 1960 to 2002. A model...

This study tests whether there is evidence of mean reversion in unemployment rates using the recently developed unit root test of Kapetanios et al. (2003). In this framework, the null hypothesis of a unit root process is tested against the alternative of a globally stationary exponential smooth...

This article estimates the effects of the financial crisis on the Swedish labour market. Using an unobserved components model and an external forecast, we estimate a future path for the Nonaccelerating Inflation Rate of Unemployment (NAIRU). Judging by this analysis, the labour market will be in...

This article investigates whether the US unemployment rate is best described as a unit-root or mean-reverting process. An out-of-sample forecast exercise is conducted in which the performance of an autoregressive (AR) model with an imposed unit root is compared with that of a mean-reverting AR...
