As recently as a month ago, I was an economics major. Since I was a little kid, how we decide what kinds of stuff gets made, and who gets it has been fascinating to me. In the same way that physics undergirds all the “reality” that the hard sciences explore, I would be so bold as to suggest that economics undergirds all that the social sciences sets out to achieve (anthropology majors, I see your glares and am ready for your refutations!). However, I would come to realize that all too often, economics is co opted by pure math and theory, and moves away from what (in my humble opinion) is the prime directive, that is, explaining how shit goes down in the real world. To that effect, I want to highlight Goodwins treatment of “unconventional” economics in pages 165-173.
The reason I love these pages so much is that Goodwin does two things that I love: attacking my heros in a persuasive way, and reassuring me that I can do less math. By showing us the way in which inflation is partially a psychological phenomena, Goodwin shows us how shaky some of Keynes ideas were in practice. It turns out that something as big as aggregate demand in a whole country is not as responsive to bureaucratic whim as we once thought. He then launches into a discussion of monopolistic competition, advertising, and indirectly, the way we imbue goods with value that isn't tied to their functionality.
But why does this matter? The fact of the matter is that we do value goods and services apart from their utility. Who cares? We should care because the terms of our economic debate is at stake. To bring Mr. Descartes back into the room, we are torn between an epistme that depends upon “rational” human actors to make the math work, and the messy, squishy world of sociology, and all its accompanying warts. As we have seen, it's a little more complicated than that.
Even then, so what? Why is it worth learning about economics? Why is the way we learn about economics important? I would argue that its importance lies not in the realms of Mr. Descartes and Pinker--because lord knows I never want to tell anyone that they need to read about supply shifters “because of the intrinsic light of knowledge”--but rather in the province of the ballot box and the supermarket. This is a question of accessibility and legitimation. What kind of economic knowledge is good currency in our policy debates. If the only kind of knowledge that is redeemable in the sphere of public debate is the highly theoretical economics that has been mathmetized within an inch of its life, requires 5 semesters of calculus, 3 of stats, and 2 more of real analysis to understand, then only a very small subset of viewpoints will be legitimated to talk about economic policy in the public square, or in the halls of congress. *WAVES BLEEDING HEART LIBERAL MEMBERSHIP CARD IN THE AIR FOR ALL TO SEE* This is why the very theoretical ideas of Freidman still have currency. They are legitimated under the terms of a very narrow discussion, and in the confines of that discussion, actually work decently well. The problem is that real economies and consumers aren't very narrow, or confined.
If, however, historians, sociologists, political theorists, scientists, and even comic book writers can have some currency, and be legitimated, more ideas that work in the real world might be able to gain some traction, and might even be understood by the average voter. Don't forget that every legitimation structure is protecting an interest. It is in the interest of special interests and eggheads at the Heritage Foundation that only the quants get to speak with authority on matters of tax policy. We take this for granted, but should we? We all interact with markets all the time? We know how messy they are, and can pretty readily conceive of the value that diverse disciplines can bring to the table. At the end, it's both a simple and radical thing that goodwin, and the unorthodox economists are trying to do. They want to introduce some doubt, remind everyone how gloriously strange human beings are, and for pete's sake, ease off on the amount of math you need to know to have an informed opinion on the messy business of markets, what gets made, and who gets it. For that, I am grateful, because while I may no longer be an econ major, you will pry my opinions and my spot in the public square from my cold, dead fingers.
