Introduction:
During the 1990s, the basic research community has been experiencing a
labor market collapse with many of the unemployment statistics for new PhDs
registering in double digits.
Unemployment Rate for New Math PhDs:
| 1989-90 | 1990-91 | 1991-92 |
1992-93 | 1993-94 | 1994-95 | 1995-96 |
| 5.7% | 12.4% | 12.7% | 12.4%
| 14.2% | 14.7% | 9.4% |
According to the analysis of pro-immigration economists
Jagdish Bhagwati and Milind Rao these gluts are largely due to the expanded
presence of foreign scholars
with the majority coming from just 4 countries: India, China, Taiwan
and Korea. Bhagwati and Rao claim that
"The traditional way in which
such 'gluts' are removed is simply by market forces: students walk away from education
that yields low rates of return. But when foreign students are in the game, the market
returns must fall more drastically before this happens. Even the currently diminished
rates of return are unlikely to turn away foreign S&E students, because even these
reduced rates return will be favorable compared to the compensation in their home
countries."
While Bhagwati and Rao acknowledge the discouraging effects of
'diminished
rates of return' on top domestic talent:
"...there is some evidence that science and
engineering programs have recently become slightly
less attractive to our best native-born students."
they claim that the benefits of sustained
downward pressure on wages are strong enough to outweigh
the concerns
"[The large presence of foreign students] means that scientist and engineer gluts, and consequent gripes
against universities, can be expected to continue.
But why should we take this as a problem? As these Ph.D.s eventually take jobs
downstream, their expertise becomes available to institutions and firms that can benefit
from superior talent and education at unexpectedly affordable prices. ...
This should be a matter for satisfaction, not lament."
We find the analysis given by Bhagwati and Rao intriguing
but as yet incomplete. Specifically, we are concerned that amidst the
benefits, there are numerous
hidden costs to flooding such a critical market.
Further, Bhagwati and Rao suppress
economic analysis of the effects
due to the field specific changes in immigration law (1976 and
1990).
Markets and Meritocracy:
The International Meritocracy: 'Brain Gain' Vs. 'Missing Minds'
The reason so much basic research remains government funded is that it fits the twin
criteria of a 'public good': discoveries are inexhaustible and (when
published) inexcludable. Conversely, this means that
many of the benefits of pure research are
available to Americans whether or not the research is performed in the U.S.
Thus, while pure research is often fueled by national interest, science
is inherently international. Accordingly,
many U.S. scientists believe that as an 'international meritocracy', science
will be
automatically benefited by a special U.S. 'open border' policy for scientists,
even in the absence of reciprocity agreements. Unfortunately, this is invalidated by a
simple labor model.
Imagine there exist only two countries: a rich one named 'Even' and a
poorer one named 'Odd'. Imagine that talent is equally distributed between
the two countries and that there are 15 Physicists, who in this simplistic
idealization can be
exactly ranked 1-15; while any random distribution will suffice, start by
assuming that those physicists with even rankings are citizens of Even and
those with odd rankings are citizens of Odd. Lastly, assume that both
countries publish their
discoveries in open journals and that the
pay differential is
moderate (e.g. U.S.A. and Canada) with all 15 preferring to work
for higher pay in Even but willing to
accept work in Odd before changing fields.
Now assume that borders can be open or closed. Here's what happens to the
international meritocracy if there are 5 jobs in each country:
Even's Borders
|
Odd's Borders
|
Hirings in 'Even'
|
Hirings in 'Odd'
|
Displaced top 10 Physicists
|
| Open
|
Open | 1-5 | 6-10 | None |
| Closed
|
Closed | 2,4,6,8,10 | 1,3,5,7,9 | None |
| Closed
|
Open | 2,4,6,8,10 | 1,3,5,7,9 | None |
| Open
|
Closed | 1-5 | 7,9,11,13,15 | 6,8,10 |
Of course if the wealth differential is made more extreme (U.S. vs. P.R.C.)
the low salaries in 'Odd' will function effectively as closed borders even
in the presence of reciprocity agreements (leading to an exacerbated
problem of 'missing minds').
It could be argued on nationalistic grounds
that the simple model above produces better local outcomes for the richer country.
Unfortunately, this is far from
automatic. When risk is incorporated into such a model, it is possible
that even the local outcome will be worsened.
Risk Aversion: A potential principal-agent problem.
There has been much discussion of the needs of scientific employers to access the
'best and the brightest'. Most of this discussion within the scientific
community differs from the parallel discussion among economists as it
possesses some curious features:
- The notion of 'best' is taken to mean 'best researcher' rather than
'best value'.
- The notion of 'best' is thought to be largely objective, and thus employer
independent.
- There is little discussion of the role of risk in scientific hiring.
It has not been much discussed that in
a labor market dominated by risk and uncertainty, expanding
access to foreign S&Es could in fact
lower expected returns to research for the country as a whole
while simultaneously providing higher 'expected utility'
to employers.
Our claim is that if the hiring of a researcher is modeled as the
acquisition of an inherently risky asset, under standard economic assumptions the US
may find its expected return on research to be decreasing as employers are
given access to a market-insensitive pool of foreign labor.
Assume for the moment that researchers are all equally priced and are
modeled by probability density functions giving the probability
of producing 'merit' at any given level. Assume further that standard
economic assumptions are applicable to the hiring of S&Es:
- There is a positive correlation between risk (variance) and return
(mean).
- Employers and funding agencies are risk averse.
- Employers and funding agencies exhibit decreasing absolute risk
aversion.
- The expanded presence of foreign scholars responding to relatively
depressed
economic conditions in their home markets pushes the number or scientists
well beyond the number of jobs.
With this in place a curious phenomena emerges. From the above perspective, the
U.S. acts as a wealthy
investor which relies on smaller co-investors (universities) to act as its agents in the
hiring of basic researchers. In such a situation, researchers fitting the high
risk-high return profile may have high 'expected utility' for the country
(the principal)
but present low expected utility for the universities (the agents).
If the number of jobs is roughly
equal to the number of researchers, then such individuals will still be
hired even if it is by lesser institutions. However, when a glut
is produced, the most original researchers may be passed over entirely
if their expected utility to risk averse universities
is lower than that of less risky candidates.
The upshot is that even if the US system of inquiry based learning is viewed
as successfully continuing its traditional production of
risk-taking/'high return'
individuals, in a glut we may expect rational universities to
pass over these innovators if given a chance to lower their risk exposure.
Opportunity costs and the American Scientist: The need for a new Todaro
Model for Scientists and Engineers
Top American science students
are economically distinguished from their foreign colleagues from LDCs in
four main ways:
- U.S. opportunity costs are vastly higher as sacrifice scales with
access to employment.
- Permanent residency and employment authorization obtained under special
immigration laws cannot be offered to Americans
as form of currency at the conclusion of training.
- The collection of special interest
immigration laws ('Special Handling', 'Schedule A', Priority 1 exemptions
for 'outstanding professors')
act as an occupation specific tax specific to university scientists and
professors.
- U.S. students do not have access to a secondary 'home market' if their US employment search
turns up empty.
In short, once these hidden variables are identified we see that we are
likely to be charging our American students more and paying them less. In
such a situation it would not be unreasonable to assume that such actions
would select against top domestic talent.
Unfortunately, in the absence of a model for the decision to seek graduate
education in science and engineering, these economic considerations are
often lost. In such situations, analysts often assume that
demographic shifts towards PhD production in the temporary visa sector are
driven by failures of merit and/or interest on the part of U.S. students.
It would be helpful to develop a common 'Todaro model' for both U.S. and
foreign students. An investment in a risky future as a researcher would be
weighed against the best safe career path available to the potential
applicant.
Morale as an input.
As the number of applicants exceeds the number of jobs, morale
suffers. Even if we were to accept the idea that our talented foreign scholars
are superior to their U.S. counterparts, we should be more interested
in maximizing their output than their numbers. If large numbers of such
researchers lead to deteriorating terms of employment, it is not clear that
degraded
morale will not have serious effects on such a mentally demanding
occupation as basic research.
Migration Statistics & Legislation
To get an idea of the shock to the system, consider that the total number
of immigrating professors in the 21 years between 1959 and 1979 was only
83% of the number immigrating in the 3 years after passage of the
Immigration Act of 1990.

University Teachers

It is then interesting to note how the immigration of professors
compares to immigration in the aggregate. Even
though both increased substantially between the passage of the 1976 and 1990
legislation, the effect is striking. 1993 provides the most dramatic
numbers to date:

We now discuss the specific provisions added by the Eilberg amendment and
the Immigration Act of 1990.
The Sheepherder Provision: Special Handling
It is a little known fact that in 1952 and 1954, congress was moved to declare a shortage of Basque
Sheepherders in the western United States. Since that time, an employers association
of ranchers (known as the 'Western Range Association') has enjoyed
anomalous immigration privileges in recognition of the hardship posed by the
alleged shortage conditions.
This would be little more than a footnote to history except that
in 1976, the Association of American Universities (AAU) succeeded in inserting
(almost unnoticed) a parenthetical clause into Title 8 of the U.S.
Code. This clause had the effect of removing the
universities from the uniform labor certification requirements and placing
them within the 'Special Handling' regulation reserved for immigrant shepherds.
The result of this switch was that Universities were granted unique
privileges found nowhere else in the economy.
For example, qualified American researchers are distinguished in that they
alone can be technically reclassified (for purposes of labor certification) as
'unavailable for work' in the event that a university succeeds in
portraying a foreign applicant as even marginally more qualified.
Curiously, in recent years the AAU has claimed that labor
certification meaningfully protects American researchers from unfair
university hiring practices. Publicly responding to charges that universities
lower their labor costs by using special immigration exemptions, AAU
president Cornelius Pings wrote:
"This is simply not true. ... in most cases where
foreign scientists are hired using permanent work
visas, universities and businesses are required to
prepare detailed labor certifications, which need to
be approved by the Department of Labor before an
individual can be hired. These certifications must
demonstrate that the person sought is being paid at
or above the prevailing wage for the position." -Cornelius Pings, Letter to
the Editor WSJ, Sept. 1996.
This is not easy to reconcile with private correspondence
between the former AAU president and the sponsor of the 1976 Eilberg
Amendment:
"...you have circumvented the primary rationale
for denial of labor certification: that an unlimited supply of
American manpower exists whose employment prospects are being
usurped by alien labor." -John Osvald, AAU President, Letter to Joshua
Eilberg, Nov. 1975.
The Shortage Provision: 'Schedule A'
While a sustained labor shortage may be nothing more than market
pressure on employers to improve wages and working conditions, short term
labor shortages can occur in skilled occupations for the duration of the time needed to
train new workers. These temporary shortages could conceivably last several
years in fields requiring extensive training.
Recognizing the legitimate needs of employers who on rare occasions may face
such emergencies, the United States maintains a (very) short list of occupations
experiencing labor shortages; this list is known as the 'Schedule A' list
of shortage occupations.
Despite the unusual levels of unemployment and underemployment which currently affect young
researchers, colleges and university employers have been listed on Schedule A as suffering
from shortages of "college and university
teachers of exceptional ability" for the last 20 years
following the passage of the
Eilberg amendment in 1976-77. Even more surprising is that under the
provisions of 'Eilberg', colleges and
universities are apparently mandated at the level of regulation to be listed as shortage afflicted
in perpetuity and without regard to future labor market conditions.
The 'Einstein Exemption': Priority 1 Aliens with Extraordinary Abilities
The U.S. has a long standing history of encouraging the immigration of
extraordinary aliens without regard to their 'market impact'. The
numbers of such researchers admitted through the granting of
'National Interest Waivers' is naturally self-limiting.
Despite the presence of these waivers, representatives of universities,
corporations and government agencies succeeded in adding (to the Immigration
Act of 1990) an exemption for priority 1 aliens with 'Extraordinary
Abilities'. Interestingly, INS records reveal that the percentage of employment based immigrants
portrayed as possessing 'extraordinary abilities' has been growing linearly
over the past 4 years in the categories governing professors and scientists:
| Percentages of Aliens Granted Permanent Residency under the Priority 1 Category
for 'Aliens of Extraordinary Abilities' | 1992 | 1993 | 1994 | 1995 |
| University and College Professors | 4.4 % | 17.8 %
| 27.8 %
| 40.1 % |
| Natural Scientists | 4.6 % | 21.4 % | 36.0
% | 52.4 % |
Despite this dramatic growth, there has been little discussion of the
underlying reasons for such seemingly high percentages.
The Anti-Shortage Quota
During the 1980s, Erich Bloch as director of NSF sounded an alarm that
the nation was going to be facing a massive shortfall of 675,000 scientists and
engineers in the 1990s and in the years to come. In response to the famous
NSF 'Shortfall' study, Congress greatly increased the number of permanent visas available
to employers. Unfortunately, later House and Senate oversight
hearings later cast doubt on the original motivations for the study:
"In 1987 the NSF adopted a plan to double its budget in
five years. There is no doubt in my mind that this shoddy science was knowingly disseminated
by the federal government's premier scientific agency to further the attainment
of this goal." -Rep. Howard Wolpe, 1992.
Despite, the fact that no labor shortage emerged, there has been no move on
the part of NSF or AAU to reverse this provision.
Issues:
- Are scientific employers misportraying foreign applicants in a
systematic fashion?
- How do we develop economic models for scientific labor markets in the
presence of so many non-monetary variables? Can revealed preference be used
to estimate the values of permanent residency, tenure, scientific job
satisfaction etc...?
- What are the expected economic consequences of exempting a particular
class of workers from the protection of uniform labor laws?
