Abstract

Using panel data from 107 private universities in Japan, we jointly estimated the translog cost function with cost-share equations. The main findings are summarized as follows; (1) There is consistent evidence of cost-minimization behavior with respect to capital, faculty staff, and other factors among private universities. (2) The demand for capital is most responsive to changes in its own price, and capital, staff, and other factors are substitutable for each other. (3) Overall economies of scale and product-specific economies of scale estimates show increasing returns to scale among private universities. (4) Scope economies were found between undergraduate and research outputs, but were not found between undergraduate and postgraduate outputs or between postgraduate and research outputs.
