Incentives
are not aligned
Commitments
lose their value when there are too many of them
A previous postings, introduced the idea that
previous politicians
have severely constrained the options available to currently-elected officials.
The first such posting focused just on debt. It was followed by a number of
postings on the loss of control implied by other decisions made by previous
politicians. One posting addressed the current situation. It was followed by
postings on the outlook for programs that constrain currently-elected officials’
ability to set priorities. The postings all focused on describing the situation
(70% of all expenditures are mandated) and the outlook (all the mandated
categories of expenditures are going to grow, some exponentially).
A logical follow-on question is: so what? Each
individual can reach his or her own conclusions about the appropriateness of
constraining the options available to currently-elected officials. Similarly,
everyone has his or her own opinion about the benefit of the different programs
that create the constraints. However, what can't be denied is that the
constraints are real, that all indications are that they will grow, and that
some of them will grow exponentially if left unmodified.
The US government was set up to put constraints on
politicians. The federal system puts constraints on what any level of
government can do. Each of the three branches of the federal government
constrains the activities of the other branches. Even our legislature was
divided into two houses in order to constrain immediate impulses of the
popularly-elected lower house while ensuring that popular impulses would be
represented. Importantly, the Bill of Rights is quite explicit in constraining
government actions. However, there isn't an apparent similar constraint that
operates over time. We’re dependent upon responsible action of previous officials
as the only assurance that future officials will have enough latitude to
govern.
As an economist and financial planner, I'll leave it
to philosophers and political scientists to address whether there are adequate
protections in the structure of our government. What is clear is that something
will have to be done. Exponential growth is never sustainable. Policy wonks and
politicians will undoubtedly put tremendous effort into trying to figure out
what to do about the situation we've gotten ourselves into. Economic and
financial planning considerations are not irrelevant.
One of the advantages of approaching it from an
economics perspective is the immediate realization that there is no good or bad
associated with the commitment to future liabilities. Economists have dealt
with analogous issues for ages. They use a concept referred to as time
preference. Early on it was illustrated by references to the decision to keep
part of the harvest as a seed crop versus consuming it. Over time, economics
has become much more sophisticated to the point where today behavioral
economists working with neurologists can literally identify the areas of the
brain involved in making decisions that involve time preference. From that they
can imply, or speculate about, how the decisions are being made.
One of the places where economists and financial
planners have a supposedly sophisticated approach to time preference is in
financial planning. It is usually referred to in the context of the time
preference for money. It can be handled by employing a concept known as the
risk-free rate of return.
Usually the rate of return on government debt is used
as a proxy for the risk-free rate of return. As is argued in an April 1, 2010 posting entitled“Beware the Risk-Free Return,” the very concept of the risk-free rate of return
is seldom appropriate. It is particularly inappropriate in this context. As the
posting states; “Sovereign entities are not too big to fail. Default isn’t an
absolute. There are a lot of ways sovereign risk can be expressed. Rates are
one.”
The risk-free rate of return falls apart when addressing
issues related to the constraints previous politicians have placed on the US.
It uses a variable (a Treasury rate) that is influenced by the constraints and,
in turn, feeds back to raise the constraints. To illustrate, one of the
concerns is that the interest burden from the debt and other mandated
expenditures will cause interest rates to rise. Those higher interest rates
will, in turn, exacerbate the debt service burden causing it to grow
exponentially.
Conceptually, when dealing with policy issues, the
equivalent of the risk-free rate of return would be what might be called the
social-rate of return on expenditures. The social-rate of return on
expenditures is a useful concept even if it can't be measured directly. It can
be used to compare the incentives of different participants in a social-policy
decision process. Whether there is misalignment between the incentives to make
future commitments and the return on those commitments is a legitimate
question.
It makes sense for politicians to commit to future
expenditures if the return on the expenditures can confidently be forecast to
be greater than the cost. That begs the question of why the politicians should
be allowed to commit to future expenditures since, if the return on
expenditures will be greater than their cost, future politicians will make the
expenditure. Further, by making a commitment based upon a belief that in the
future expenditures will be justified, politicians are introducing additional
risk. They are introducing the risk that they are wrong in their forecast of
future returns on those expenditures. Given those two facts, it's hard to see
how to justify the current level of commitments. It suggests that a misalignment
of incentives may exist.
However, before reaching that conclusion, one needs
to consider another justification for the commitments. That justification is
that there is a social return to the commitment itself. The best example
familiar to anyone in finance is the low interest rate paid by nations that
have a long history of, and thus implied strong commitment to, meeting their
sovereign obligations.
It isn't just financial markets where future
commitments have value. Theoretically, citizens and businesses benefit from
knowing that the government has made a certain commitment. For example, the
commitment to Social Security and Medicare is an input into retirement planning.
The burden of financial planning for retirement is lightened to the extent one
can count on those programs. A commitment to certain rights of
property benefits both individuals and the economy in general. Neither
individuals nor businesses can plan if they don't know what they own and what
ownership implies.
The value of the commitment depends upon two things:
(1) The degree to which there is confidence in the commitment, and (2) the
nature of the expenditures that are being promised. The nature of the expenditure that results in
a commitment has to be addressed individually for each expenditure. Further, it
is very dependent on personal preferences regarding the expenditure. Therefore,
it is more fruitful to address how the value of commitment relates to the
degree of confidence one can put in the commitment.
For shorthand, one can refer to how the value of the
commitment relates to the degree of confidence in the commitment as simply the
value of the commitment. The value of a commitment isn’t constant. For example,
the April 1, 2010 posting pointed out evidence that, at that time, investors
were placing more confidence in certain corporate debt than they were in Treasury
debt. Similarly, surveys currently indicate many younger Americans have no
confidence that they will receive Social Security benefits. So, there is ample
evidence that politicians have made commitments to future expenditures far
beyond the point of diminishing returns.
The value of the future commitment is discounted
based upon the risk that the commitment will not be met. That risk rises the
more commitments there are. In the US, the magnitude and nature of the
commitments has reached the point where there are so many commitments that they
are all being discounted at a steeper rate than historically. Historically, the
first commitment required less of the budget, and therefore was easier to meet.
Plus, that commitment didn't have to compete with other commitments made by the
government.
Commitments have value even if they are steeply
discounted. Economists have techniques for handling situations where costs
increase while returns are falling. However, those techniques assume that the
costs and returns both affected the same entity. That assumption is
inappropriate for government expenditures especially when the commitments are
across multiple generations. The costs may be borne by a group totally
different from the one that receives the benefits.
It isn't just the distributional issue. The dilemma
is that both the costs and returns to the commitments are different from a
social perspective versus a political perspective. From a political perspective,
as long as the commitment has any value, there is an incentive to make the
commitment. The costs are not born by the current politician. By contrast, from
a social perspective, the commitment must have value that exceeds the future
cost. So, it is highly likely that there are many commitments that have
political value that far exceed their value to society. To some extent, that
explains why such a large portion of future tax revenue has been committed by
previous politicians.
However, it would be very convenient to simply blame
politicians. Given the population’s current low regard for politicians as
indicated by the polls, it's an easy out. Unfortunately, the problem is much more
serious. Politicians may just be responding to legitimate choices being made by
the electorate.
If the value of commitments to expenditures in the
future has dropped because of heightened risk that the commitments won’t be
honored, one would expect it to be necessary for politicians to make
increasingly large commitments to future expenditures. To illustrate, if one
gets a commitment for $10,000 and is sure it will be received, it is considered
to be worth $10,000 at that future date. If one believes there's only
about a 10% chance that the future commitment will be met, the commitment has
to be for $100,000 to have the same value of $10,000 at that future date.
A second response would be for politicians to reduce
the time horizon over which the value of the commitment is discounted due to
risk the commitment will not be met. In other words, politicians have an
incentive to make the commitment so immediate that the risk that future
politicians wouldn't meet it is irrelevant.
Both affects would encourage politicians to make
commitments to mandated expenditures that are immediate and large. In essence,
the incentive is to make commitments that have immediate expenditure
consequences but delayed cost consequences. By degrading the value of
governmental commitments to expenditures, the debt becomes the preferred to
option.
To
summarize, there is a misalignment of incentives that encourages
over-commitment to mandated programs. Over-commitment decreases the value of
the commitments by increasing the risk that they won't be met. That shortens
the potential time horizon for such commitments and encourages debt financing
of those commitments.
