I couldn’t
decide when to write this week’s blog post. I could do it right now (Friday)
and free up the weekend for dancing like Zorba and drinking like Putin. Or I could wait until late Monday night and do
it at the Varsity like my roommate Jim K did his homework back in 1965. I was
never good at procrastinating and went ahead and starting writing this on
Friday. That decision made me think of other timing issues. For examples see
some of my favorites below and feel free to write in your own:
·
Pay
our national debt now or maybe later?
·
Fight
ISIS now or maybe later?
·
Allow
most illegal immigrants a route to citizenship now or maybe later?
·
Turn
in your elderly husband now or maybe later?
·
Discipline
your child holding the screwdriver near the electrical outlet now or maybe later?
·
Vigorously
attack global climate change now or maybe later?
·
Replace
your 1963 Lada now or maybe later?
·
Stop
Putin’s geographic aggression now or maybe later?
·
Cheat
on your income tax this year or maybe later?
·
Open
up a personal saving account now or maybe later?
So you get
the drift, right? Isn’t it amazing how so many of our most pressing decisions
and challenges revolve around WHEN to act. It is not a simple yes or no. We
know acting is important but the question is when.
Luckily
economists who got tired of macro and location theory pioneered a concept called the "cost of waiting". Unluckily for us, most of these models are framed
in models that require an abacus and very advanced mathematical knowledge like
foot stomping. So let me just outline the basics of an economist’s theory about
the cost of waiting.
First, we assume that there is something that needs to be
done. Let’s call that – taking your dog Rufus for a walk.
Second, we assume that we have some leeway as to when Rufus gets his exercise.
Third, there are benefits associated with waiting until
later. For example, you just poured a lovely JD and you don’t want the ice
cubes to melt and water it down too much. After all, the JD people went to a lot
of trouble to create that lovely taste. Also, you are watching the Ellen show
and you heard that LL Cool J is coming on soon wearing a short Kilt.
Fourth, there are costs associated with waiting. Rufus is
walking around in circles for a good reason. He has to pee right now. Rufus cannot
take himself for a walk since that violates HOA rules. And you are the only one
who can clean that expensive room-size woven Persian rug.
So there you
are – you are now an expert in cost of waiting models. And you realize you can
make a truly objective and life maximizing decision by measuring and comparing
the extra costs versus the extra benefits of waiting one more minute. Here are
the three decision rules:
If the extra cost of waiting one
minute exceeds the extra benefit, then go now.
If the extra benefit is greater than
the extra cost of waiting one more minutes, then wait at least another minute.
If the extra costs and benefits of
waiting one more minute are equal, then kiss your dog, pet your wife, and say
goodnight Dick.
So here is
my question. Of the issues I listed above, to what extent do any of the
arguments you hear and read focus on anything close to a real analysis of the
costs and benefits of waiting? Or to put it another way – if the main arguments do not fit
the model, then what do they fit? This
is where ideology comes in – and causes a real mess that prevents a real solution.
Let’s take
climate change. Liberals want much more done right now to stop climate change.
They refer to models that show dramatic negative consequences of waiting too
long. Do they ever discuss the benefits of waiting? Do they assume these benefits are all
zero? Or do liberals simply assume they are negligible. Maybe liberals would be
more believable if they even pretended to act as if this were not another ideological
preference.
Conservatives
like me are pretty vocal about the national debt. We make a strong case for the
possible future costs associated with waiting to reduce the size of the debt. We can
be quite colorful in describing a Greek-like future for the US economy. But
liberals say pashaw or dude or something like that. Dude, lots of countries
have large national debts and they do just fine. Maybe conservatives in a rush
to reduce the US debt should spend more time evaluating the benefits of waiting
on the debt? Or are they surely zero? Maybe we conservatives would be more believable
if we at least faked an even-handed analysis of the costs and benefits of waiting.
Some might
say that letting the liberals and conservatives debate these issues will bring
out all the sides of the decision to wait and then voters can decide for
themselves. Well, it seems to me that day is over. People have already lined up
ideologically. They care little for a real analysis. They just want to be
on the side that wins. Is this the kind of democracy we fought so hard to
preserve? Does economic analysis become useless in such a world?
