“A theory of citations” by Wojciech Olszewski
We propose a model in which researchers maximize their number of citations in subsequent papers. The equilibrium is inefficient, because they distort their effort towards writing on popular topics. This inefficiency is smaller when citations in time-remote papers have a higher weight, and when citations in higher-ranked journals have a higher weight. We also discuss some other issues, for example, the relation between the quality of papers and the number of citations, and the relation between efficiency and the spread of citations across papers.
