The purpose of this paper is to carry out an empirical examination of the supply-side factors influencing dropout rates in MBA programs. We analyze the extent to which the resources and characteristics of the program (content, teaching methodology, course load, class size, partnerships, reputation) influence these rates. A GLM analysis was conducted on data obtained from a final sample of 94 executive MBA programs in Western Europe. The results indicate that several supply side factors significantly affect dropout: intensity of case study learning, number of credits per month, class size, and proportion of lessons given at partner institutions. Several implications for the design and management of higher education programs have been drawn from this research.
