I saw Senator McCain on CNN talking about how the stimulus package is,
essentially, reaching into the pockets of future generations and transferring
their wealth to the present generation. He kept talking about how much poorer future generations will be as a result of the debt the stimulus package (never mind that he voted for tax cuts that would have made the deficit much worse, e.g. "It’s 'generational theft,' said Senator John McCain, just a few days after
voting for tax cuts that would, over the next decade, have cost about four times
as much.").
So let's look at this and see if the generational theft charge has any foundation or, as is more
likely given recent history, it is mostly scare tactics being used in an
attempt to manipulate public opinion.
To begin, think about how the government finances, say, $10,000 in deficit spending. To
use debt finance (as opposed to raising taxes or printing money), the government
will print up a piece of paper - we call it a government bond - and write "IOU
$10,000 plus interest" on it. It then trades the "IOU $10,000 plus interest at
some point in the future" for $10,000 in cash. Thus, the private sector gives
the government $10,000 and gets an IOU (a bond) in return.
Let's suppose the government then takes this money and spends it on a project
such as a road that has benefits for a wide segment of the population. The end
result, then, is that the money was borrowed from an individual and distributed
through government spending (or transfer payments) to a larger segment of the
population.
So far, there hasn't been any transfer of resources from the future to the
present, only a transfer a resources within the current generation. What about
when the bond is paid off, does that transfer resources across generations? Let's suppose it is a 30 year bond, and that the
holder passes away and bequeaths it to his or her children. Thus, thirty years
from now the bond comes due, and the holder cashes it in and is paid in full.
But where does the money come from? The government pays it out of its tax
revenue. That is, the government collects the $10,000 plus interest from the
future generation, then gives taxes it collects to the bond holder.
But this is a transfer of resources within a generation, not across
generations. A whole bunch of people in the future will have to pay higher
taxes, and the taxes they pay will go to a smaller number of individuals holding
the debt. But across the population the assets and liabilities cancel exactly,
there is no net aggregate burden. Liabilities have passed to future generations, but so have the corresponding assets.
Thus, the current generation cannot use government deficits to literally
reach into the pockets of future generations and steal their resources. But that
doesn't mean that deficits are always harmless. There are three ways that debt
can make future generations worse off, the question is whether these are
important considerations right now. So let's look at three ways debt can be
problematic and see if we should be worried about them in the present
environment.
First, financing the debt can cause interest rates to rise. If interest rates
rise, investment is lower and that can lower future economic growth. Thus, if
this effect is operative and strong, there is a sense in which higher output
today is traded for lower growth in the future.
This effect, commonly called crowding out, is worrisome when the economy is
running at or near full employment and competition for resources is intense, but
right now with interest rates as low as they are and with so much slack in the
economy, this is not much of a worry. Government borrowing will not put upward
pressure on interest rates, and hence private sector investment - to the extent
firms are willing to undertake it in such poor conditions - won't be much
affected.
Second, the collection of taxes in the future can cause distortions, and those distortions
can lower economic growth. This is simply the usual supply-side economics story.
This will likely bring the supply-side fanatics and ideologues out of the
woodwork, but I don't believe the evidence supports the claim that these effects
are large (e.g. see "Final
grade on the Bush tax cuts: Failure to produce jobs"). So there's nothing
much to worry about here either.
Third, if we borrow from foreigners rather than ourselves, the debt can
impose a net aggregate burden within the US. To see this, use the example above
where the government borrows $10,000, but this time let's suppose the money is
borrowed from the foreign sector. In this case, we borrow from the foreign
sector, and then at some point in the future the debt is paid off and this
involves a flow of resources out of the U.S. Because resources flow out of the
U.S. instead of simply being redistributed within the U.S., this imposes a net
burden.
But there are two important qualifications. If we use the money to build
something that provides benefits to current and future generations that exceed
the value of the resources flowing out of the country, there is still a net
benefit from the transaction. It depends upon what is done with the money. If it
is used, for example, to build things like infrastructure and schools, then
future generations get a benefit along with a bill, and it is the net effect
that matters.
The second qualification is that while we borrow from foreigners, we also
hold foreign assets and if you look at the net resource flow, the flow of funds
outward from foreigners owning our debt, and the flow inward from our owning
foreign assets, the net flow is positive. So overall these transactions do not
detract from the living standards of future generations. [Update: I should have also added that these considerations are independent of countercyclical fiscal policy. The value from using countercyclical fiscal policy to enhance economic stability - something that does not necessarily require capital expenditures by the government (e.g. investment in infrastructure) - also needs to be taken into account.]
When you put all of this together, it seems very clear that the Republican
opposition is misplaced and, though it's par for the courses they play on,
unduly alarmist. But you may not believe me, so let me add two other sources for
the same message.
Let's start with a textbook treatment from Baumol and
Blinder's Macroeconomics text (9th ed.):
Bogus Arguments about the Burden of the Debt
Having gained some perspective on the facts, let us now turn to some of the
arguments advanced by those who claim that budget deficits place an intolerable
burden on future generations.
Argument I Our children and grandchildren will be burdened by heavy interest
payments, which will necessitate higher taxes.
Answer It is certainly true that a higher debt means higher interest payments
and, therefore, higher taxes on our children and grandchildren. But think who
will own the bonds and therefore receive the higher interest payments as income:
our children and grandchildren! Thus, one group of future Americans will be
making interest payments to another group of future Americans. So we conclude
that:
As long as the national debt is owned by domestic citizens, as the majority
of the U.S. debt is, future interest payments transfer money from one group of
Americans to another. These transfers mayor may not be desirable, but they
hardly constitute a burden on the nation as a whole.
However, this argument is valid-and worrisome-for the portion of our debt
that is held by foreigners, a share that has been growing rapidly and is now
over 40 percent. Paying interest on this portion of the debt will burden future
Americans in a concrete way: For years to come, a portion of America's GDP will
have to be sent abroad to pay interest on the debts we incurred in the 1980s,
1990s, and 2000s. For this reason, many thoughtful observers are becoming
concerned that the United States is borrowing too much from abroad.
Another valid element of this argument is that the taxes that will have to be
raised to pay interest even to U.S. citizens may reduce the efficiency of the
economy.
Argument 2 Repaying the enormous debt will ruin the nation.
Answer A first answer to this argument merely rephrases the answer to the
previous one: Most of America's debt is owed to Americans. But this argument
raises an even more fundamental point. Unlike a private family, the nation
need never payoff its debt. Instead, each time the principal is due, the
U.S. Treasury can simply "roll it over" by floating more debt. Indeed, that was
done routinely for decades.
Was this a bit of chicanery? How could the U.S. government get away with
making loans that it never intended to pay back? The answer lies in the fallacy
of comparing the U.S. government to a family or an individual. People cannot
borrow in perpetuity, because they will not live that long. Sensible lenders
will not extend long-term credit to very old people because their heirs cannot
be forced to pay up. But the U.S. government will never "die" - at least, we
hope not! So this problem does not arise. In this respect, the government is in
much the same position as a large corporation. GE never pays off its debt. It,
too, rolls it over by floating new debt all the time.
Argument 3 Like any family or any business firm, a nation has a limited
capacity to borrow. If it exceeds this limit, it is in danger of being unable to
pay its creditors. It may go bankrupt with calamitous consequences for everyone.
Answer This is another false analogy. While private debtors and many foreign
governments have to worry about defaulting on their debt, the U.S. government
does not. Why not? First, because it has enormous power to raise revenues by
taxation. If you had such power, you would never have to fear bankruptcy either.
But once again, the statement raises a more fundamental point - one that
distinguishes the U.S. debt from that of most other nations. The American
national debt is an obligation to pay U.S. dollars: Each debt certificate
obligates the Treasury to pay the holder so many U.S. dollars on a prescribed
date. But the U.S. government is the source of these dollars. It prints them!
No nation need default on debts that call for repayment in its own currency.
If worse comes to worse, it can always print whatever money it needs to pay off
its creditors. This option is not open to countries whose debts call for payment
in U.S. dollars, as a number of Southeast Asian countries learned in 1997 and
Argentina learned in 2001.
It does not, of course, follow that acquiring more debt through budget
deficits is necessarily a good idea. Sometimes it is a very bad idea. As we
know, printing money to pay the debt will expand aggregate demand and cause
inflation. In addition, as we will learn in Chapter 18, printing more dollars
should make the international value of the dollar fall. We may not relish either
of these outcomes. The point is not that budget deficits are either good or bad;
they can be either under the appropriate circumstances. Rather, the point is
that worrying about a possible default on the national debt is unnecessary and
even foolish.
Next, Dean
Baker:
Government debt can either increase or decrease the wealth of
future generations. The debt itself is not a measure of the financial impact
across generations. What matters is how the debt affects the strength of the
economy when the government borrows the money.
It is easy to see that the national debt is not really a measure
of intergenerational burden. While the taxpayers collectively can be seen as
owing the debt, taxpayers (or at least some of them) also own the debt. This is
not a payment across generations; it is a payment within generations.
If the United States let the debt rise to $10 trillion and then
left the debt at $10 trillion for 100 years, just paying the interest, then in
2108 some of our children, grandchildren and great grandchildren would be
collecting the interest on the $10 trillion, which would be paid from the taxes
that the government collects.
This flow of money from taxpayers to bond holders doesn’t on net
make people better or worse off 100 years from now. It is simply a
redistribution from some members of future generations to other members of
future generations. None of the interest is flowing to those of us alive now,
since virtually all of us will have passed into history by then.
Whether or not the debt has made future generations poorer will
depend on how it was incurred. If we ran up debts so that we could finance
schools and colleges, and make sure that our children and grandchildren were
well educated, then we probably made them richer than if we didn’t run up debt
but left them illiterate. Similarly, if we ran up the debt to construct a modern
physical and information infrastructure, then we probably made future
generations much wealthier than if we had handed them a country that was debt
free, but had no Internet and no computers.
In short, the debt is not an accurate measure of whether we have
been generous to or short-changed the generations that come after us. The answer
to that question depends on the economy and society that we pass on. There are
many scenarios in which we would have impoverished future generations, even if
we were to hand them a government that is free of debt or alternatively left
them very wealthy, even if there is a substantial government debt.
There is an economic argument whereby deficits can reduce the
wealth of future generations. If the economy is at its capacity (e.g. everyone
who wants to work is already employed), then if we run a large deficit due to
additional government spending or tax cuts, then we may be pulling people away
from building up the economy’s capacity. Specifically, the government’s
borrowing needs can lead to higher interest rates.
Higher interest rates can in turn lead to less investment. If
businesses invest less in machinery, computers, and other investment items, then
productivity will grow less rapidly. Productivity, how much workers produce in
an hour of work, is the main long-run determinant of living standards. ... (Productivity almost always grows, so
the issue is how fast it grows – it is almost impossible to envision a future in
which workers are not substantially more productive in 20 or 30 years than they
are today.)
If a deficit leads to high interest rates, which in turn reduce
investment, then they will have slowed the economy’s growth and made future
generations less well off than they would have been without the deficits. But it
is important to remember that the way deficits can hurt future generations is
not directly through the debt burden, but rather because they can reduce
investment and therefore slow productivity growth.
The measure of the deficit’s impact on the living standards of
future generations is not the size of the debt in dollars or even the size of
the debt relative to the size of the economy. The impact of the deficit on
future living standards would be reflected in the rate of productivity growth.
If the deficit has actually hurt the living standards of future generations,
then it would be because deficits lead to slower productivity growth than the
country would have otherwise seen.
In fact, even as the economy has run up substantial deficits in
recent years, productivity growth has been strong for most of the last 15 years.
Productivity has grown at an average annual rate of 2.5 percent in the years
from 1995 though the second quarter of 2008. This means that for each hour of
work, we are getting 38.6 percent more of output today than we did in 1995. In
principle if the country as a whole is spending the same percentage of its time
working in 2008 as in 1995, then we can be enjoying a standard of living that is
38.6 percent higher than in 1995.
While there is an issue that a greater share of the economy’s
output might be diverted to foreigners because of the foreign debt (see below),
we still derive more income each year from our ownership of foreign assets than
foreigners do from their ownership of U.S. assets. At the moment at least, we
are still in the process of making our children much wealthier than we were, in
spite of our $9 trillion debt.
