Republicans have predicted that the just passed GOP tax cut
bill will work like gangbusters on the economy. And they are right, but
for the wrong reason. Tax cuts don’t stimulate the economy, but government
deficits do, and the GOP tax cut bill promises to increase the federal deficit by around $1.1 trillion.
The same thing happened with the Reagan tax cuts in the
1980s. People forget the bad economy during the first part of the Reagan
administration and only remember the strong economy after the 1981 tax cuts
were passed without any corresponding spending cuts. The cuts were
supposed to “pay for themselves” but when they didn’t, the deficit
soared. Reagan and the Congress then passed tax increases to
control the deficit (no one remembers “Ronald Reagan, tax raiser”), but the
initial stimulus created the “Reagan miracle” of an improved economy.
Why doesn’t a tax cut stimulate the economy? Don’t tax
cuts put more money in people’s wallets? Let’s look at the impact of a
state tax cut on a state economy, one where the state has to maintain a
balanced budget since states can’t pay for tax cuts by printing money.
Every dollar of tax cuts must be accompanied by a dollar of lower state
spending, whether it be on education, social services, or the proverbial waste,
fraud and abuse. So the economy is stimulated by greater private
spending, but retarded by less public spending. The economy can’t tell
the difference between a dollar spent by the state or a dollar spent by a
private citizen; the net effects cancel out.
But wait, there’s more (as the infomercials say)!
Under standard economic theory, people don’t spend every cent of every dollar
they earn. Most people, especially those who are not in poverty, save
some of their income for the proverbial rainy day. Let’s assume that the
typical person saves 5% of their income and puts it under their mattress, or in
a nice savings account. That means that a dollar tax cut only produces 95
cents of actual stimulus.
The government, of course, does not save for a rainy day (at
least, not usually; some states, like California, have a “rainy day fund” to help
the state during economic downturns. But these funds are usually a small
percentage of the budget and are quickly exhausted during an economic
downturn). So when a state cuts taxes, it forgoes spending 100 pennies in
order to give a dollar to a taxpayer who will then spend 95 pennies. Thus
state tax cuts do not stimulate the economy, they actually make it less robust.
Federal tax cuts can stimulate the economy, but only when
they are accompanied by increased deficits. It is the deficit that
improves the economy, not the tax cut. Republicans claim
they hate the federal deficit, but they love cutting taxes that makes the
deficit bigger.
There is one possible rebuttal to this analysis, that tax
cuts do increase savings but savings are used by banks to lend capital, and
capital is used to build businesses up. That is factually true, but the
mechanism by which increased investment leads to economic growth is not well
understood, and the benefit should be delayed by several years. Also, increasing
the deficit by printing money will affect both inflation and interest rates in
ways that difficult to anticipate. That spending (either private of
governmental) stimulates the economy is straightforward and incontrovertible.
So the GOP tax bill might stimulate the economy in the short
run, but eventually the deficit-hawks are going to start demanding spending
cuts (or tax increases) to pay for them and when that happens the economy will
dip into another recession. Yes, Republicans may think that taking food
stamps away from hungry children is a lot of fun, but the money in that social
program (and others) goes to farmers who support their families by buying
consumer goods, and it then is spent by providers of consumer goods on their
families, and so on and so on ad infinitem.
The next stage in this pantomime is that after a slight boom
the economy will start to lag, Republicans will say it is the deficit’s fault
and urge spending cuts in social programs, Democrats will counter with
proposals to pare back on the tax cuts, Republicans will accuse the Democrats
of wanting to raise taxes yet again, and meanwhile the deficit will
grow.
The irony is that the Republicans are right to worry about
the deficit, but will attempt to benefit politically from making the problem
worse. Will voters be smart enough to realize this? That is what
the 2018 midterm elections will show.
