In this paper we suggest panel data unit root tests which allow for a potential structural break in the individual e¤ects and/or the trends of each series of the panel, assuming that the time-dimension of the panel, T , is ...xed. The proposed test statistics consider for the case that the break point is known and for the case that it is unknown. Monte Carlo evidence suggests that they have siz...

Missing data or missing values are a common phenomenon in applied panel research and of great interest for unit root testing. The standard approach the literature is to balance by removing units and/or trimming time period all units. However, this can be costly terms lost information. Instead, existing tests could extended case unbalanced panels, but often difficult because observations affect ...

in this paper, we analyze the dynamics of income gap between 138 countries with usa by using time series model of convergence hypothesis and various panel unit root tests over period 1950-2008. all panel unit root tests don’t reject the null hypothesis of unit root. univariate unit root tests results show that gdp per capita of south korea, switzerland, austria, lesoto and hungry catch up with ...

This paper introduces a dynamic panel data model with exogenous variables where the dynamic behavior is allowed to differ between cross-section units. The framework is a mixture model obtained by mixing two regression model with different paramters according to some mixing weights. The parameters in the model are estimated by the method of maximum likelihood, and it is shown that the maximum li...

The existence of a long-term positive relationship between the nominal interest rate and general price level is called Gibson paradox in economics literature. In other words, according to this paradox, high prices are result rates. Studies on literature gained momentum after work (1923). main purpose study test whether valid for ASEAN-T countries with quarterly data 1993:Q1-2019:Q4. context, sh...

This paper proposes two new panel unit root tests based on Zaykin et al. (2002)'s truncated product method. The first one assumes constant correlation between p-values and the second one uses sieve bootstrap to allow for general forms of cross-section dependence in the panel units. Monte Carlo simulation shows that both tests have reasonably good size and are powerful in cases of some very larg...

The notion of a ripple effect in the housing market implies stationarity in regional:national house price ratios. The central aim of this study is to investigate whether the ripple effect exists in Taiwan’s regional house price ratio by implementing the Breuer et al. (2001) Panel SURADF unit root tests, which can improve upon the less efficient estimations of conventional unit root tests. The P...
