I want to thank the Editor of the Singapore Economic Review, Professor Euston Quah, for giving researchers in panel data econometrics in general and me in particular the opportunity and the faith to expose via this journal the relevance and merits of panel data research for empirical economics. I am grateful to the SER editorial office, in particular to Julianna Yik Sho Yuen, for the secretarial support. I also want to thank all the anonymous referees for their indispensable advice, and last but not least all (co-)authors of the included articles for the work they produced.
