An MBA degree increases the general human capital of its holder. My university has both day and night MBA curricula. Students in the day program almost always pay their own fees those in the night program are typically olderand work full time durig the day, and their employers sometimes pay their fees. Payment by employers appears to be inconsistent with our reasoning about why students are more likely to pay for their general human capital. When might it be rational for an employer to pay? Why night students?
