Do Larger Federal Budget Deficits
Stimulate Spending? Depends on Where the Funding Comes From
The U.S. equity markets have rallied in the wake of
Donald Trump’s presidential election victory. Various explanations have been
given for the stock market rally. President-elect Trump’s pledge to scale back
business regulations are favorable for various industries, especially financial
services and pharmaceuticals. Likewise, President-elect Trump’s vow to increase
military spending is an undeniable plus for defense contractors. But another
explanation given for the post-election stock market rally is that U.S.
economic growth will be stimulated by the almost certain business and personal
tax-rate cuts that will occur in the next year, along with the somewhat less
certain increase in infrastructure spending. It is this conventional –wisdom
notion that tax-rate cuts and/or increased federal government spending
stimulate domestic spending on goods and services that I want to discuss in
this commentary.
Although I have been a recovering Keynesian for decades,
I got hooked on the Keynesian proposition that tax-rate cuts and increased
government spending could stimulate domestic spending after having taken my
first macroeconomics course way back in 19 and 65. I was so intoxicated with
Keynesianism that I made a presentation about it in a political science class.
I dazzled my classmates with explanations of the marginal propensity to consume
and Keynesian multipliers. My conclusion was that economies need not endure
recessions if only policymakers would pursue Keynesian prescriptions with
regard to tax rates and government spending. Reading the body language of my
classmates, I believed that I had just enlisted a new cadre of Keynesians. That
is, until one older student sitting in the back of the class raised his hand
and asked the simple question: Where
does the government get the funds to pay for the increased spending or tax
cuts? I had to call on all of my obfuscational talents to keep my
classmates and me in the Keynesian
camp.
When I graduated from college with a degree in economics,
I still was a Keynesian, perhaps a bit more sophisticated one, but not much. At
graduate school, I became less enchanted with Keynesianism. But Keynesianism is
similar to an incorrect golf grip. If you start out playing golf with an
incorrect grip, you will have a tendency to revert to it on the golf course
even after hours of practicing at the driving range with a correct grip. Bad
habits die hard. So, even though I had drifted away from Keynesianism, it was
easy and “comfortable” to slip back into a Keynesian framework when performing
macroeconomic analysis. Yet, I continued to be haunted by that question my
fellow student asked me: Where does the government get the funds to
pay for the increased spending or tax cuts?
I guess I am a slow learner, but after a number of years
in the “real world”, away from the pressure of academic group-think, I realized
that tracing through the implications of where
the government gets the funds to finance tax-rate cuts and increased spending
is the most important issue in assessing the stimulative effect of changes in
fiscal policy. And my conclusion is that tax-rate cuts and increased government
spending do not have a significant
positive cyclical effect on economic
growth and employment unless the
government receives the funding for such out of “thin air”.
Let’s engage in some thought experiments, beginning with
a net increase in federal government spending, say on infrastructure projects.
Let’s assume that these projects are funded by an increase in government bonds
purchased by households. Let’s further assume that the households increase
their saving in order to purchase
these new government bonds. When households save more, they cut back on their current spending on goods and services, transferring this spending power to
another entity, in this case the federal government. So, the federal government
increases its spending on infrastructure, resulting in increased hiring,
equipment purchases and profits in the infrastructure sector of the economy.
But with households cutting back on their current spending on goods and
services, that is, increasing their saving, spending and hiring in the
non-infrastructure sectors of the economy decline. There is no net increase in spending on
domestically-produced goods and services in the economy as a result of the
bond-financed increase in infrastructure spending. Rather, there is only a redistribution in total spending toward the infrastructure sector and away from other sectors.
What if a pension fund purchases the new bonds issued to
finance the increase in government infrastructure spending? Where does the
pension fund get the money to purchase the new bonds? One way might be from
increased pension contributions. But an increase in pension contributions
implies an increase in saving by the
pension beneficiary. The pension fund is just an intermediary between the
borrower, the government, and the ultimate saver, households or businesses
saving for the benefit of households. Again, there is no net increase in spending on domestically-produced goods and
services in the economy.
What if households or pension funds sell other assets to
nonbank entities to fund their purchases of new government bonds? Ultimately,
some nonbank entity needs to increase its saving to purchase the assets sold by
households and pension funds. Again, there is no net increase in spending on domestically-produced goods and
services in the economy.
What if foreign entities purchase the new government
bonds? Where do these foreign entities get the U.S. dollars to pay for the new
U.S. government bonds? By running a larger trade surplus with the U.S. That is,
foreign entities export more to the U.S. and/or import less from the U.S.,
thereby acquiring more U.S. dollars with which to purchase the new U.S.
government bonds. Hiring and profits
increase in the U.S. infrastructure sector, decrease in the U.S. export or
import-competing sectors.
Now, let’s assume that the new government bonds issued to
fund new government infrastructure spending are purchased by the depository
institution system (commercial banks, S&Ls and credit unions) and the
Federal Reserve. In this case, the funds to purchase the new government bonds
are created, figuratively, out of “thin air”. This implies that no other entity
need cut back on its current spending on goods and services while the
government increases it spending in the infrastructure sector. All else the
same, if an increase in government
infrastructure spending is funded by a net increase in thin-air credit, then
there will be a net increase in spending on domestically-produced goods and
services and a net increase in domestic employment. We cannot conclude that an increase in
government infrastructure spending funded from sources other than thin-air credit will unambiguously result in a net
increase in spending on domestically-produced goods and services and a net
increase in employment.
President-elect Trump’s economic advisers have suggested
that an increase in infrastructure spending could be funded largely by private
entities through some kind of public-private plan. This still would not result
in net increase in U.S. spending on domestically-produced goods and services
and net increase in employment unless
there were a net increase in thin-air credit. The private entities providing
the bulk of financing of the increased infrastructure spending would have to
get the funds either from some entities increasing their saving, that is, by
cutting back on their current spending, or by selling other existing assets
from their portfolios. As explained above, under these circumstances, there
would be no net increase in spending on domestically-produced goods and
services.
Now, it is conceivable that an increase in infrastructure
spending, while not resulting in an immediate
net increase in spending on domestically-produced goods and services, could
result in the economy’s future potential
rate of growth in the production of goods and services. To the degree that
increased infrastructure increases the productivity of labor, for example,
speeds up the delivery of goods and services, then that increase in
infrastructure spending could allow for faster growth in the future production of goods and services.
Another key element in President-elect Trump’s proposed
policies to raise U.S GDP growth is to cut tax rates on households and
businesses. To the degree that tax-rate
cuts result in a redistribution of a given amount of spending away from pure
consumption to the accumulation of physical capital (machinery, et. al.), human capital (education) or
an increased supply of labor, tax-rate cuts might result in an increase in the future potential rate of growth in GDP, but not the immediate rate of growth
unless the tax-rate cuts are financed
by a net increase in thin-air credit.
At least starting with the federal personal income tax-rate
cut of 1964, all personal income tax-rate cuts have been followed with
cumulative net widenings in the federal budget deficits. So, for the sake of
argument, let’s assume that the likely forthcoming personal and business
tax-rate cuts result in a wider federal budget deficit. Suppose that households
in the aggregate use their extra after-tax income to purchase the new bonds the
federal government sells to finance the larger budget deficits resulting from
the tax-rate cuts. The upshot is that there is no net increase in spending on
domestically-produced goods and services nor is there any net increase in
employment emanating from the tax-rate cuts.
My conclusion from the thought experiments discussed
above is that increases in federal government spending and/or cuts in tax rates
have no meaningful positive cyclical
effect on GDP growth unless the
resulting wider budget deficits are financed by a net increase in thin-air
credit, that is a net increase in the sum of credit created by the depository
institution system and credit created by the Fed.
Let’s look at some actual data relating changes in the
federal deficit/surplus to growth in nominal GDP. I have calculated the annual calendar- year federal
deficits/surpluses, and then calculated these deficits/surpluses as a percent
of annual average nominal GDP. The red bars in Chart 1 are the year-to-year
percentage-point changes in the annual budget deficits/surpluses as a percent
of annual-average nominal GDP. The blue line in Chart 1 is the year-to-year
percent change in average annual nominal GDP. According to mainstream Keynesian
theory, a widening in the budget deficit relative to GDP is a “stimulative”
fiscal policy and should be associated with faster nominal GDP growth. A
widening in the budget deficit relative to GDP would be represented by the red
bars in Chart 1 decreasing in magnitude, that is, becoming less positive or
more negative in value. According to
mainstream Keynesian theory, this should be associated with faster nominal GDP
growth, that is, with the blue line in Chart 1 moving up. Thus, according to
mainstream Keynesian theory, there should be a negative correlation between changes in the relative budget
deficit/surplus and growth in nominal GDP. The annual data points in Chart 1
start in 1982 and conclude in 2007. This time span includes the Reagan
administration’s “stimulative” fiscal policies of tax-rate cuts and faster-growth
federal spending, the George H. W. Bush and Clinton administrations’
“restrictive” fiscal policies of tax-rate increases and slower-growth federal
spending and the George H. Bush administration’s “stimulative” fiscal policies
of tax-rate cuts and faster-growth federal spending.
Chart 1
In the top left-hand corner of Chart 1 is a little box
with “r=0.36” within it. This is the correlation coefficient between changes in
fiscal policy and growth in nominal GDP.
If the two series are perfectly correlated, the absolute value of the correlation coefficient, “r”, would be equal
to 1.00. Both series would move in perfect tandem. As mentioned above,
according to mainstream Keynesian theory, there should be a negative correlation between changes in
fiscal policy and growth in nominal GDP. That is, as the red bars decrease in
magnitude, the blue line should rise in value. But the sign of the correlation
coefficient in Chart 1 is, in fact, positive,
not negative as Keynesians
hypothesize. Look, for example, at 1984, when nominal GDP growth (the blue
line) spiked up, but fiscal policy got “tighter”, that is the relative budget
deficit in 1984 got smaller compared to 1983. During the Clinton
administration, budget deficits relative to nominal GDP shrank every calendar
year from 1993 through 1997, turning into progressively higher surpluses relative to nominal GDP
starting in calendar year 1998 through 2000. Yet from 1993 through 2000,
year-to-year growth in nominal GDP was relatively steady holding in a range of
4.9% to 6.5%. Turning to the George H. Bush administration years, there was a
sharp “easing” in fiscal policy in calendar year 2002, with little response in
nominal GDP growth. As fiscal policy “tightened” in subsequent years, nominal
GDP growth picked up – exactly opposite from what mainstream Keynesian theory
would predict.
Of course, there are macroeconomic policies that might be
changing and having an effect on the cyclical behavior of the economy other
than fiscal policy. The most important of these other macroeconomic policies is
monetary policy, specifically the behavior of thin-air credit. In Chart 2, I
have added an additional series to those in Chart 1 – the year-to-year growth
in the annual average sum of depository institution credit and the monetary
base (reserves at the Fed plus currency in circulation). “Kasrielian” theory
hypothesizes that there should be a positive
correlation between changes in thin-air credit and changes in nominal GDP. With
three variables in chart, Haver Analytics will not calculate the cross
correlations among all the variables. But E-Views will. And the correlation
between annual growth in thin-air credit and nominal GDP from 1982 through 2007
is a positive 0.53. Not only is this correlation coefficient
1-1/2 times larger than that between changes in fiscal policy and nominal GDP
growth, more importantly, this correlation has the theoretically correct sign in front of it. By adding growth in
thin-air credit to the chart, we can see that the strength in nominal GDP
growth in President Reagan’s first term was more likely due to the Fed,
knowingly or unknowingly, allowing thin-air credit to grow rapidly. Similarly,
the reason nominal GDP growth recovered from the George H. W. Bush presidential
years and was relatively steady was not
because tax rates were increased in 1993 and federal spending growth slowed,
but rather because growth in thin-air credit recovered in 1994 and held
relatively steady through 1999.
Chart 2
In sum, there may be rational reasons why the U.S. equity
markets rallied in the wake of Donald Trump’s presidential election victory.
But an expectation of faster U.S. economic growth due to a more “stimulative”
fiscal policy is not one of them unless the larger budget deficits are financed with thin-air credit. Fed
Chairwoman Yellen, whether you know it or not, you are in the driver’s (hot?)
seat.

Even under PPP, thin-air credit is an important element. Most PPP's rely heavily on bank debt for project financing, which is thin-air credit, often for 70-80% of capital structure.
ReplyDeletePaul, as always, your thorough and insightful analysis makes me think. Just wondering if the correlation between deficits and nominal GDP growth would be higher if one of the data series was lagged. For example, based on your charts, it appears that nominal GDP growth jumps up in the few years after big deficit spending. Thanks, Sean.
ReplyDeleteDoes marginal propensity to consume come into this infrastructure question? E.g., I have 20k sitting in an account, I don't live pay check by pay check, gvt yields go up a bit and I decide to put 10k of that into gvt bonds (funding infrastructure). The money is used in an infrastructure project and pays salaries (let's say) of people who have a higher marginal propensity to spend than I do - so effectively we just have a bit of money moving from one MPC level to another MPC level, but it causes more money to circulate - what do you think? I'm sceptical about whether and to what degree there will be any increase in infrastructure spend, but I thought your thought experiment was really well constructed and just have this follow-up query... thanks for your continued writing
ReplyDeleteGreat,
ReplyDeletegreat read. I thoroughly enjoyed reading about . Love this post!!
It’s so interesting to see the statistics of a lifestyle we are trying to make work for us.It sounds as
if you have worked yourself to where you want to be . Congratulations and continued good fortune!
