Since introduction of unit roots, researchers have tried to solve the purchasing power parity (PPP) puzzle or its failure by testing for stationarity of the real exchange rates. Failure to support the PPP is mostly said to be due to low power of these tests. Panel unit root testing is more...

The hysteresis hypothesis in unemployment for ten European countries are tested using newly developed Panel SURADF tests of Breuer et al. (2001) for the 1961-1999 period. While the other Panel-based unit root tests are joint tests of a unit root for all members of the panel and are incapable of...

This note uses the newly developed panel SURADF tests advanced by Breuer et al. (2001) to investigate the time-series properties of real GDP for 47 African countries for the period 1980 to 2004. While the other Panel-based unit root tests are joint tests of a unit root for all members of the...

In this study, we revisit the issue as to the presence of rational bubbles in the US stock market during the 1871 to 2002 period using both the Johansen cointegration and the Bierens 1997 nonparametric cointegration tests. The results from the conventional Johansen cointegration test fully...

In this note two competing hypotheses are empirically tested, namely those of the demand-following and supply-leading, using multivariate VAR models for Mainland China over the period 1987Q1 to 1999Q4. Johansen cointegration results indicate that there exists one cointegrating vector among GDP,...

This note provides evidence that there exist long-run benefits for Taiwan investors from diversifying in the equity markets of the Hong Kong, Japan, South Korea, Thailand and the USA over the period of 6 January 1997 to 30 December 1998. The evidence is based on tests for pairwise cointegration...

In this study, we apply the panel Seemingly Unrelated Regressions Augmented Dickey-Fuller (SURADF) tests developed by Breuer et al. (2001) to revisit the validity of Purchasing Power Parity (PPP) for 16 Latin American countries. The empirical results from several panel-based unit root tests...

This paper evaluates monthly stock index price from the Taiwan stock market for evidence of weak form market efficiency. Four empirical methodologies are employed: the Ljung-Box Q test, the binomial distribution test, the runs test and the unit root test of stationarity in stock prices....

This study applies threshold cointegration test advanced by Enders and Siklos (2001) to investigate the properties of asymmetric adjustment in long-run Purchasing Power Parity (PPP) for China during the period of March 1985 to September 2008. Although there is evidence of long-run PPP for China,...

Purchasing Power Parity (PPP) for transition economies is tested using Panel Seemingly Unrelated Regressions Augmented Dickey-Fuller (SURADF) tests of Breuer et al. (2001) for the period of January 1995 to December 2008. Although the other panel-based unit-root tests are joint tests of a unit...
