When E.F. Hutton Talks
The concept of utility is the most fundamental concept in economics. It
gets wrapped up in impressive sounding terms like “exogenous preference
functions”, and written in all sorts of arcane runes and formulas, but all
utility means is that you like something more than something else. The
assumptions that economic theory makes about utility are really pretty simple
and mostly about consistency — if you like vanilla ice cream more than
chocolate ice cream, and chocolate more than strawberry, then economic theory
assumes you also like vanilla more than strawberry — and continuity — if you
like one scoop of vanilla ice cream, then you like two scoops even more. But as
far as what you like, what your tastesor preferences are
in ice cream or music — or health insurance plans — economic theory is
intentionally silent. Economics is all about making rational decisions given
some set of likes and dislikes. It doesn’t presume to tell you what you should
like or dislike, and it assumes that you do in fact know what you like or dislike.
Or at least that’s what economic theory used to proclaim. Today economic
theory is used as the intellectual foundation for a political stratagem that
goes something like this: you do not know what you truly like, and in
particular you do not know your economic self-interest, but luckily for you we
are here to fix that. This is the common strand between QE and Obamacare. The
former says that you are wrong to prefer
safety to risk in your investments, and so we will fix that misconception of yours
by making it extremely painful for you not to take greater investment risks
than you would otherwise prefer. The latter says that you are wrong to prefer no health insurance or a certain
type of health insurance to another type of health insurance, and so we will
make it illegal for you to do anything but purchase a policy that we are
certain you would prefer if only you were thinking more clearly about all this.
