The Economics of Reducing Faculty Teaching Loads: Comment

In a recent article in this Journal, McKenzie (1972) sought to demonstrate with elementary indifference-curve analysis the impact of changes in maximum teaching or research loads on the levels of teaching and research undertaken by a faculty member. This note indicates that a basic constraint has been omitted from McKenzie's model and that its inclusion invalidates his results. The analysis will also be extended to incorporate the influence of income, which was omitted from McKenzie's model, on the allocation of faculty time between teaching and research activities. McKenzie's model may be summarized as follows. Minimize disutility U(T, R) subject to a constraint T = H rR, where T and R are time spent on teaching and research, H is the maximum teaching load, and r is the number of units of T which can be traded for a unit of R. The first-order conditions for this problem are:
