Nelson’s basic thesis is that economics is more like a religion than a science.
In fact, he argues that economics in the twentieth century has virtually
supplanted organized religion with a creed of material progress. Within
economics Nelson analogizes Samuelson and company as being more like Roman
Catholics who adhere to natural law doctrine, such as the efficacy of market
institutions with a strong overlay of government regulation. Chicago economists
are more like Calvinists in that they are radical revolutionaries in the
pursuit of a more libertarian approach to economic life in general.
The half of me that wants to like the book reflects an admiration for Nelson’s
scholarship. His thesis is new and novel; he has written a strong brief for it,
and to say the least, he has interesting ideas. Stylistically, he wins me over.
The other half resists the extremity of the argument. There is no doubt that
modern economics is full of value judgments, both implicit and explicit, and
that one must use care in separating positive from normative arguments. Where
the argument is normative, one must be as explicit as possible about what the
value judgments are and whether individuals are in general agreement with
respect to these judgments. In most cases, the normative aspects of economic
analysis are benign and easily accepted — for example, more wealth or utility
is better than less, material progress is a good thing, market institutions
stimulate economic growth (this is also a positive prediction), and so on. Of
course, there will be dissenters; we do not live in a Pareto – optimal world.
But for the most part, the normative assumptions of modern economics are not
controversial. So while Nelson is right that there is a “religious” sub-text to
economics, I do not think it is such a big deal. Most of these value judgments
are just common sense writ large.
At times Nelson seems to deny the prospect of a value-free analysis. Here, I
think he goes too far. Positive economics is alive and well in academia, and
the economic paradigm of choice within constraints is being pushed steadily
forward to new frontiers of explanation (including religion). There are no
hidden values here; there is no sub-text. There is a simple desire to explain
the world as it is in a more understandable way. The relevant question to these
scholars is not how but why? Most of the work that Nelson discusses in the
modern Chicago approach and in the New Institutional Economics is this type of
analysis. And while understanding the world per se may actually lead to social
change, I do not think this correlation is thought about or stressed very much
by these analysts. Their focus is on understanding, not changing, the world.
Still, on net, I give Nelson high marks for making an interesting and useful
argument. It is always good to take stock of what we are about as professional
One final note is that Nelson may be right about the demise of economics in
universities. One way to look at the issue is to note that the great economic
debate is over. Capitalism won, so that the demand for the “religious” services
of economists is on the wane.
