This paper discusses the methodology of quantitative measures of research output. The authors illustrate various approaches to the contentious issue of to how to treat co-authored papers, how to best affiliate migrating authors, and how to quantify the quality of economic periodicals.
The authors also summarize the main findings from the three papers published in this issue, which are devoted to the quantification of publishing activity of Czech and Slovak economists, and which reveal a high concentration of research activity in only a few institutions in the Czech and Slovak republics and the rather convoluted standards of promotion in Czech universities.
