Determinants of international university rankings scores

This article analyses the relationship between a university's score in international university rankings, its expenditure per student and other factors such as university mission, size and productive inefficiency. We develop an economic model of rankings and universities and estimate this model with data on universities classified in the top 200 by the Times Higher Education Supplement ranking of 2007. We find that the elasticity of a university's ranking score for the expenditure per student is between 4% and 9%, and that there are no clear signs of inefficiency in production among the top 200 universities. University mission and size are also significant predictors of ranking score. These results are especially interesting given the relevance attributed to rankings by government officials, university directors and students.
