The unrecognised benefits of grade inflation
Raphael Boleslavsky, Christopher Cotton 16 August 2014
Grade inflation is widely viewed as detrimental, compromising the quality of education and reducing the information content of student transcripts for employers. This column argues that there may be benefits to allowing grade inflation when universities’ investment decisions are taken into account. With grade inflation, student transcripts convey less information, so employers rely less on transcripts and more on universities’ reputations. This incentivises universities to make costly investments to improve the quality of their education and the average ability of their graduates.
Since the early 1980s, the mean grade point average at American colleges and universities has risen at a rate of between 0.1 and 0.15 points per decade. Most of this increase can be attributed to an increase in the share of As assigned (which now comprise nearly half of all grades), with significant drops in the assignment of lower grades (Rojstaczer 2011 and Rojstaczer and Healy 2012).
