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
from 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. ...[adds supporting quotes from Baumol and Blinder's textbook, Dean Baker]...
As noted, most of these points are also made in Baumol and Blinder's textbook, but there are some qualifications to note. First, on the effect of lending to foreigners,
. Second, on whether its possible to transfer resources across generations,
