The authors examine and compare the schooling efficiency of business schools at universities in Taiwan using Data Envelopment Analysis (DEA) and data from a survey conducted by the Ministry of Education (MOE). We set up and decompose the standard Mincer earnings equation as in Portela and Thanassoulis (2001) and construct efficiency measures based on current and starting salaries. Evidence suggests that although schooling efficiency among individual schools is rather obvious, there is no significant difference between public and private universities, implying that firms pay higher wages to public school graduates due to incomplete information in labor productivity.
