The present levels of Ph.D. unemployment have multiple, interrelated
causes.
During the late 1980's, the number of Ph.D.'s produced grew
from a low of 726 in 1984-85 to a peak of 1202 in 1992-93. An influx
of foreign students accounted for 72% of this increase [AMS
Survey]. The more cynical attribute much of this increase to ``The
Myth,'' a badly flawed 1987 NSF study forecasting a future shortfall of
675,000 natural scientists and engineers, but it is clear that this is
not the full story.
Colleges and universities, under intense financial pressures
due to cutbacks in federal spending on higher education as well as the
recent recession, have been reducing faculty sizes. The American
Council on Education's 1993 Campus Trends report indicates that 40% of
doctoral-granting institutions have procedures underway to cut back on
the number of full-time faculty, mainly through attrition [ACE, 1993].
The AMS reports that there were 31% fewer positions offered in math
departments in 1992-93 than in 1989-90 [AMS Survey]. Universities are
making up lost teaching capacity with temporary and part-time workers,
with 52% of ACE surveyed institutions reporting extensive use of
part-time faculty (i.e. more than one-fourth of courses in these
institutions were taught by part-time faculty) [ACE, 1993].
Corporations, faced with an increasingly competitive global
economy, have been paring back research and development budgets. In
addition, global companies which once hired research mathematicians no
longer have to look to U.S. labs to provide the best researchers. Sun
Microsystems, for example, has begun to fund Russian scientists for
some of its research in parallel operating systems; Lotus has an
extensive software development facility in Bangalore, India.
The budgets of military research labs and defense contractors
have been slashed as a result of the end of the Cold War.
The total number of scientists has been growing exponentially
at a rate faster than the growth of the population. David Goodstein,
provost of Cal Tech, points out that the current oversupply of
scientists is the inevitable result of this disparity in growth rates
[Goodstein, 1993].
