This study uses Monte Carlo analysis to investigate the performances of five different meta-analysis (MA) estimators: the Fixed Effects (FE) estimator, the Weighted Least Squares (WLS) estimator, the Random Effects (RE) estimator, the Precision Effect Test (PET) estimator, and the Precision...

This paper examines power issues for the ADF and four break models (Perron 1989, Zivot and Andrews 1992) when the DGP corresponds to one of the break models. Choosing to test an incorrect break model can but need not greatly reduce the probability of rejecting the null. Break points that are...

If the researcher tests each model in a battery at the a % significance level, the probability that at least one test rejects is generally larger than a %. For five unit-root models, this paper uses Monte Carlo simulation and the inclusion-exclusion principle to show for a %=5% for each test,...

This Phillips-Ouliaris (1988) non-parametric unit root test for non seasonal data and the seasonal one of Joyeux (1992) are based in the estimation of the spectral density function in a fixed frequency. We can get consistent estimations of the spectrum using spectral windows, but such procedure...

Non-spherical errors, namely heteroscedasticity, serial correlation and cross-sectional correlation are commonly present within panel data sets. These can cause significant problems for econometric analyses. The FGLS(Parks) estimator has been demonstrated to produce considerable efficiency gains...

This paper presents unit-root test results for real exchange rates in ten Central and Eastern European transition countries during 1993:01-2003:12. Because of the shift from controlled to market economies and the accompanying crises, failed policy regimes and changes in exchange rate regimes,...

This study focuses on a comparison and evaluation of models and estimators appropriate for time-use data. The tobit type I as well as different generalizations are used. According to our findings, a simple tobit I method can produce results that are similar and in some cases even better to the...
