Economic science is turning into advocacy economics. This
was on full display during the election and will be going forward as the
economic agenda of President-elect Trump is debated. Many economists have
already warned us about the dire consequences of Trump’s platform. However,
their advocacy often reveals double standards and internal contradictions which
may well explain how poor they have proved to be in predicting a policy’s
actual outcome.
A good example of the rise in advocacy economics is the
debate about Trump’s proposed tax policy. One of the first economic lessons of
taxes is that the people sending checks to the tax collectors may differ from
the people truly made poorer by the tax. For example, sales taxes are submitted
by retailers but may be borne by consumers. The corporate tax is paid by
businesses, but the burden is partially borne by workers through lower wages
and consumers through higher prices.
Harris-supporting economists often stressed that tariffs
levied on foreign companies will act as sales taxes, not borne by foreign
companies but pushed onto U.S. consumers. However, in the same breath they
claim that Trump’s promised corporate tax cuts are a tax break for
billionaires. Advocacy economics runs into credibility problems when arguing
that taxes levied on foreign firms are not borne by the rich people who run the
companies but that taxes on domestic firms are. Taxes on domestic firms are pushed
onto consumers just as taxes on foreign firms are. The beneficiaries of
corporate tax cuts include American workers, consumers, and shareholders.
All taxes have harms, so while imposing taxes on foreign
firms may potentially hurt Americans, imposing taxes on American firms also
hurts us, if not more. Tariffs on the small share of our spending that is on
imports may raise prices, but tax cuts on firms contributing to the much larger
share of our spending that is not on imports may lower prices. It seems prudent
to consider whether replacing taxes on domestic firms with taxes on foreign
firms while keeping tax revenue neutral, a part of the RNC platform, may
benefit Americans. But of course, we cannot raise all revenue that way. The
Laffer curve is real: Uncle Sam won’t raise enough from tariffs to wipe out the
income tax.
For labor markets, advocacy economics again runs into
problems with logic. Much economic research by left-leaning economists has for
decades argued that legal immigration has a limited impact on natives’ wages.
But we now hear the same economists warning us that deportation of illegal
immigrants will be highly “inflationary” by cutting the number of available
workers. Advocacy loses credibility if claiming a rise in supply does not
affect price, but a cut in supply does.
On a broader level, the Keynesian framework accepted as
conventional by many economists and policy-makers is based on the underlying
belief that government officials can time fiscal and monetary policy to dampen
the business cycle while controlling price growth. But its advocates repeatedly
disagree with the timing of policies implemented by government officials. To
illustrate, take the case of Larry Summers, who correctly argued that Biden’s
fiscal policies would be inflationary and that the Fed was too slow in
responding. But either the Keynesian framework he adheres to is useful because
government officials are good at timing policy, or it isn’t useful because it
is too difficult for them, or anyone, to do. Which is it?
A large part of this headache-inducing advocacy occurs
because of the virtue-signaling of economists who work in academia, one of the
most left-leaning sectors in the American economy and one where, just like
Hollywood, being on the wrong team dampens your career.
The loudest advocacy comes from Nobel economists who
insist on signing letters predicting the opposite of what actually happens.
Having served decades at the University of Chicago, the global leader in the
Nobel count, I know firsthand that their research focuses on more general
issues distant from specific election platforms, and few even read the
platforms. In addition, many Nobel winners sign letters outside their area of
expertise, which is like asking a psychiatrist to comment on a surgical procedure.
This may explain letters predicting an economic
Armageddon in the event of a Trump win in 2016, that the nationalization of
student lending would help fund the Affordable Care Act, and that massive
redistribution would generate higher long-run growth, through Biden’s Build
Back Better.
The Nobel winners’ most recent letter warning of Trump
was challenged by market indices rising 4–5 percent immediately after the
election — a large gain given that the victory was already somewhat baked into
prices since the election was a toss-up according to polls and Trump was
favored in prediction markets. This advocacy problem mimics 2016 when the index of
small-business optimism went through the roof directly after the election. The
faulty academic predictions are not surprising: Asking the academy to evaluate
Trump is like asking Pepsi to evaluate Coke.
Let’s hope more rational assessments can help America
evaluate Trump’s economic agenda. Americans deserve to be informed by economic
assessments that are built on logic and evidence, not on advocacy.
