“The Disposable Academic”


POSTED BY:

This weeks Economist has an article subtitled, “Why doing a PhD is often a waste of time” (subscription required). Many of the items reported are familiar for those who read phds.org, but a few new things stood out:

PhD production is growing rapidly outside the US. This means possibly additional opportunities in overseas universities, but greater competition for filling them.:

Between 1998 and 2006 the number of doctorates handed out in all OECD countries grew by 40%, compared with 22% for America. PhD production sped up most dramatically in Mexico, Portugal, Italy and Slovakia. Even Japan, where the number of young people is shrinking, churned out about 46% more PhDs.

This statistic was particularly striking:

the production of PhDs has far outstripped demand for university lecturers. In a recent book, Andrew Hacker and Claudia Dreifus, an academic and a journalist, report that America produced more than 100,000 doctoral degrees between 2005 and 2009. In the same period there were just 16,000 new professorships.

I’m puzzled by their PhD production numbers – 100,000 sounds pretty low to me – but the 6-to-1 ratio of PhDs to professorships sounds similar to what I’ve heard for the fraction of life sciences postdocs that ever get tenure track positions. Indeed, from Richard Freeman:

There is a glut of postdocs too. Dr Freeman concluded from pre-2000 data that if American faculty jobs in the life sciences were increasing at 5% a year, just 20% of students would land one.

PhDs outside of academia often end up doing things not closely related to their studies, so their advanced degrees don’t buy them much additional earning power:

A study in the Journal of Higher Education Policy and Management by Bernard Casey shows that British men with a bachelor’s degree earn 14% more than those who could have gone to university but chose not to. The earnings premium for a PhD is 26%. But the premium for a master’s degree, which can be accomplished in as little as one year, is almost as high, at 23%. In some subjects the premium for a PhD vanishes entirely. PhDs in maths and computing, social sciences and languages earn no more than those with master’s degrees. The premium for a PhD is actually smaller than for a master’s degree in engineering and technology, architecture and education.

The suggested remedies are standard fare: better training in transferable skills and better metrics.

One interesting concrete realization of the training improvements is the UK’s New Route PhD (trademarked!).

    It is only useful for professorship, thus grant access to graduate studies to only one candidate over six.
