In a previous article, Struther Arnott recommended that expansion of t
he university system should be concentrated entirely in, those univers
ities with fewer than 600 teaching staff, which he advocated as the id
eal size of university in the UK. Larger universities were alleged to
suffer diseconomies of scale arising from unspecified problems of orga
nization and management. Michael Bourn challenges many of these argume
nts as fundamentally flawed. It is suggested, instead, that research-b
ased and teaching-based universities will develop divergent patterns o
f average cost per student.
