Co-Authorship and Co-Citation Networks in the Agricultural Economics Literature: The Case of Central and Eastern Europe

Abstract

This article analyzes co-authorship and co-citation networks in the agricultural economics literature on Central and Eastern Europe written during the last twenty-five years. It highlights the principal researchers in the field, together with their authorship and citation networks, on the basis of 238 articles written between 1990 and 2013. Most of the articles were written by a small number of researchers, indicating that clusters and central authors play an important role in scientific progress. Contrary to expectations, it turns out that number of articles and central role in network are not related. Finally, clusters are found to cite themselves more than the average, thereby boosting scientific progress for their members.
