This letter reconsiders the empirical tests of the new Keynesian and new classical models performed by Ball Mankiw and Romer and Akerlof, Rose and Yellen. The original tests conform basically to cross-section analysis; we develop both time-series and pooled cross-section, time-series tests of...

The lag in effect of monetary policy contains vital information for the policy evaluation. Allowing for a time-varying treatment effect, we show that Inflation Targeting (IT) effectively lowers inflation for both developed and developing countries. Developed countries reach their targets rapidly...

The United States banking industry experienced a period of poor performance in the late 1980s. Significant problems with loans as reflected in loan loss provisions and net charge offs hampered bank profitability. We examine the effect of portfolio composition on net charge offs at large...

In this study, the panel Seemingly Unrelated Regressions Augmented Dickey-Fuller (SURADF) tests advanced by Breuer et al. (2001) are used to test the validity of Purchasing Power Parity (PPP) for G-7 countries over the period 1980M1 to 2008M5. The empirical results from several panel-based unit...

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...

The panel Seemingly Unrelated Regressions Augmented Dickey-Fuller (SURADF) tests advanced by Breuer et al. (2001) are used to test the validity of Purchasing Power Parity (PPP) for eight major oil-exporting countries over the 1992:06 to 2008:02. Empirical results from several panel-based unit...

In this study, the panel Seemingly Unrelated Regressions Augmented Dickey-Fuller (SURADF) tests advanced by Breuer et al. (2001) are used to test the validity of Purchasing Power Parity (PPP) for 15 countries belonging to the Common Market for Eastern and Southern Africa (COMESA) and the...

This empirical study applies panel SURKSS tests, proposed by Wu and Lee (2009), to investigate the properties of long-run Purchasing Power Parity (PPP) in a sample of 10 Latin American Integration Association (LAIA) countries over the period January 1980 to September 2008. The empirical results...
