Citation‐Capture Rates for Economics Journals: Do they Differ from Other Disciplines and Does it Matter?

Abstract

This paper compares the rate of citation-capture across the social sciences, sciences, business school disciplines and economics. It also explores differences in the rate of citation-capture between leading journals in economics and a representative science category, and between higher and lower ranked economics journals. Short-term citation counting as used in impact factors and journal ranking schemes is shown to favour sciences over social sciences. In addition, within economics, short-term impact factors are systematically biased towards lower ranked journals. Our results imply that the use of leading multidisciplinary journal rankings as a proxy for direct citations introduces an unreported bias in research assessment. Such biases are in addition to those attributable to the well-known differences in the total number of cites received by papers across various disciplines.
