Determinants of publication productivity: an empirical analysis

Academic performance is typically measured as some combination of teaching, publishing, and professional service. This paper focuses on the publication aspect of academic output, estimating the determinants of publication productivity using data for Robert D. Tollison (RDT). Robert Tollison published 433 articles and books, and collaborated with 524 coauthors while at a dozen institutions over thirty-eight years. Our findings indicate that RDT's output is significantly correlated with several factors, including co-authorship, the diversification of his research portfolio, business cycles, and academic pay. To a lesser extent, his production pattern is influenced by non-work interests and specific institutional affiliations.
