A bibliometric analysis of health economics articles in the economics literature: 1991-2000.

This paper describes and analyzes trends in health economics articles indexed in the economics literature from 1991 to 2000, demonstrating the robust state of publication in the field during the past decade. While articles, pages, and the number of journals increased, single authorship declined dramatically from almost half of articles published to only one-third, and papers with four or more authors increased three-fold. Over three-fourths of articles were analyses of healthcare markets or health production, while policy oriented articles constituted the third largest share. Author concentration ratios decreased almost by half and the Herfindhal-Hirschman index of author concentration declined from 14 in 1991 to only 4 in 1999. Copyright 2003 John Wiley & Sons, Ltd.
