Not so Dismal
a Science
Addressing public issues in ways many policymakers
do not
Every Sunday coaches in the National Football League must
make high-stakes decisions under intense public scrutiny.
What, for example, should a team do when faced with a particular
fourth-down situation? A bad choice could end a season,
even a coaching career. David Romer, a professor of economics
at the University of California at Berkeley, thinks he can
help. To be sure, there are more pressing economic issues
facing the world—Romer himself writes extensively
on monetary policy—but in a paper entitled “It’s
Fourth Down and What Does the Bellman Equation Say?”
Romer has come to the rescue of the oft-besieged head coach.
Be aggressive, Romer counsels. Where, Red Sox fans cry out,
was baseball’s equivalent to David Romer when Grady
Little most needed him?
In
late September, just as the energy accompanying the opening
of school begins to dissipate, I give students in my economics
class a New York Times article about David Romer’s
analysis. I use this short piece in part to change pace,
to start a discussion that can at once be academic and anything
but academic. My deeper purpose, though, is to ensure that
studying the dismal science does not seem so dismal. My
experience teaching economics at Milton has shown me that
it doesn’t have to be. Economics students, even those
who will not pursue further study in the field, can grow
intellectually in ways that permit them to be engaged, critical
participants in public life.
As Romer’s work suggests, many economists
seem increasingly eager to apply their skills and understanding
to issues that seem far from the realm of gross domestic
product figures and the latest NASDAQ numbers. Cruise through
the list of working papers at the National Bureau of Economic
Research, and you can find titles like “Catholic Schools
and Bad Behavior,” “Choosing between War and
Peace,” and “Carrots, Sticks and Broken Windows.”
The authors of these studies are not engaged in some quest
to capture someone else’s academic turf. Rather, they
are addressing important public issues in ways that many
policymakers do not. Although Milton students are not typically
ready for the more complex quantitative analysis that characterizes
professional work, they too can begin applying fundamental
economic concepts to seemingly non-economic issues. For
example, the basic notion of opportunity cost, an idea covered
in the first few weeks of the course, comes as a near revelation
to many students. In much the same way, the essential elements
of the supply-anddemand model open some students’
eyes to a new way of thinking. With just those ideas in
mind, they can read Nobel Prize winner Gary Becker’s
analysis of drug legalization and engage in vociferous and
intellectually vibrant debate over the nation’s drug
policy. Or they can begin conceptualizing the ways in which
we can reform the organ transplant system. Should we pay
people to donate organs? Should we reward needy patients
who have lived healthy lives?
Milton students recognize that economists
alone can’t tell us whether to legalize marijuana
or to pay for a particular kidney transplant—we need
the help of political theorists, philosophers, perhaps even
theologians to resolve vexing social problems. It is therefore
beneficial that Milton’s economics courses are part
of the history and social sciences department’s broader
examination of the human experience. Still, the economist
can provide new insights and fresh evidence that is useful
to all of us as we make individual and collective decisions.
Sunny Ladd’s work, for example, may not provide the
very last word on education reform, but we ignore her work
and work like it at our own peril. The point is not to elevate
the work or tools of economists above all else, but rather
to expand the intellectual repertoire of students. We say
that we want students to ask tough questions; an introduction
to economics helps them to do just that.
We would prefer, of course, that students
could answer some questions as well. In accomplishing this
goal, an introductory economics course is only partially
successful. A few core principles provide the basis for
most good answers, but the complexity and interdependence
that characterize the global economy can at times make simple
answers elusive. I often suggest, only partially in jest,
that there are always two possible answers to any economic
question: “opportunity cost” and “it depends.”
(When pressed I sometimes add a third—“I don’t
know”—but I have great difficulty finding professional
economists who have made a career by admitting as much in
print.) Part of the trouble lies in human behavior. Economic
models often rest on assumptions about how people will behave,
and certain folks just don’t meet the models’
expectations. It’s no surprise that behavioral economists
and professors of psychology now push the field forward,
and each year Milton students engage in a series of exercises
designed to test assumptions underlying game theory. In
an effort to introduce some new interdisciplinary approaches,
several years ago I collaborated with my colleague Ellie
Griffin, teacher of Milton’s Advanced Placement Pyschology
course, to develop material appropriate for both economics
and psychology students. For most economics students, though,
it’s not the mystery of human nature but the mystery
of public discourse that can be most confusing.
Take the terminology of macroeconomics.
Most of us bemoan high levels of unemployment. But what
does it take to be unemployed in the government’s
eyes? And once we know what the standards are for being
“unemployed,” what does the “unemployment
rate” tell us? I typically give students a series
of articles about the calculation of the unemployment rate,
including Austan Goolsbee’s article “The Unemployment
Myth” in which he contends that “the government
has cooked the books” by reclassifying some unemployed
people as disabled. Students read similar pieces when we
examine the terms “growth,” “inflation”
and “poverty.” The meaning of an apparently
simple statistic is not always simple, Its significance
is not always straightforward. The selective, deceptive
usage of numbers in public debate only confuses matters
further. Thus, students find that simply describing current
conditions in a single nation can be rather challenging.
Moving beyond description adds complexity.
World-renowned economists argue bitterly about the causes
and consequences of certain economic phenomena, and their
disputes over recommended policy are no less passionate.
Such differences could discourage the budding student of
economics, but most Milton students seem to avoid disillusionment.
Rather, they begin to ask difficult questions about the
causes of the disagreements. Are some economists blinded
by ideological commitments? Are some economists making unreasonable
assumptions? Do all economists give credence to the same
body of evidence? Here, of course, Milton students are playing
to their strength, once again asking questions. With the
experts in disagreement, though, students (and teachers)
must ask those questions with a healthy degree of humility.
Understanding the world, never mind recasting it, is pretty
hard work.
Indeed, despite the limits inherent in
a brief introduction to economic thinking, my commitment
to teaching this material has only increased. Milton at
its best instills in its students a desire to engage with
rather than retreat from the world beyond. No shortage of
challenges—or to put it in a more positive way, no
shortage of opportunities—greet Milton students as
they look to the future. And though it is commonplace to
advance the specious claim that forces beyond our control
dictate our fate now and forever, most of the economics
students that I teach leave the course energized, not enervated.
They know that decisions about taxing and spending matter,
and they can articulate why. They know that decisions to
embrace and restrain market forces matter, and they can
articulate why. They know that decisions about international
trade matter, and they can articulate why. (They also know
that according to one recent study, children raised in neater
houses are likely to enjoy higher earnings. Not a crucial
bit of knowledge for them, but parents take note!) These
students know that they—and we—can make better
choices. With that knowledge, and with a whole host of good
questions, the future filmmakers, the future investment
bankers, and—especially—the future football
coaches who graduate from Milton are a bit better prepared
to take seriously the responsibilities of citizenship.
