Joachim Schnurbus, Harry Haupt, and Verena Meier, "Economic Transition and Growth -- A Replication", Journal of Applied Econometrics, Vol. 32, No. 5, 2017, pp. 1039-1042. This paper uses the data set that appeared in Peter Phillips and Donggyu Sul, "Economic transition and growth", Journal of Applied Econometrics, Vol. 24, No. 7, pp.1153-1185. See http://qed.econ.queensu.ca/jae/2009-v24.7/phillips-sul/ for the readme file and the original data. The file PS-Clubbing-Functions.R contains the functions for computing our proposed version of the algorithm of Phillips and Sul (2007, 2009), while the file PS-Clubbing-PWT-Results.R contains the reproduction of the Phillips and Sul (2009)-results and the example showing the effect of our code adjustments. Both these files are zipped in the file shm-programs.zip. Unix/Linux users should use "unzip -a".
