I never got around to commenting on the infamous Economist list of influential economists; they’ve been given plenty of deserved grief, to which I needn’t add. But I think I might have something useful to say about a fact that is really unmistakable when you look at a list corrected by removing central bankers, or make a more subjective judgment: these days, the economist as public intellectual is overwhelmingly likely to be a liberal.

As Noah Smith says, it was not always thus. He argues that the field of economics has changed, with greater emphasis on market failures, and there’s arguably something to that. I’d also argue that the descent of right-leaning macroeconomics into hermetic absurdity matters quite a lot, because macro looms larger in the public sphere than it does within the academy.

But there’s another important factor. Modern conservatism doesn’t have Friedman-like figures — people who would be prominent economists thanks to their research whatever their politics, who are also public intellectuals– because it doesn’t want them. The movement prefers hacks, who needn’t be even minimally competent but can be counted on to defend the party line without any risk of taking an independent stand.

Let me offer my own two short subjective lists. I think if you were going to name the two current econoheroes of U.S. liberals they would probably be Joe Stiglitz and yours truly. (Thomas Piketty has made a huge and well-deserved splash, but so far only on one issue.) The thing that is obvious about Joe is that before becoming a public figure with a political following he established his reputation with vast amounts of widely cited academic research; you can get a sense of what he did by looking at his top entries on Google Scholar. And here are mine.

Now, who would be the conservative counterparts? Who gets cited by, say, Republican governors seeking authority for their tax cuts, or published on a regular basis on conservative opinion pages? I’d say Stephen Moore and Arthur Laffer. No point in looking them up on Google Scholar, although Laffer does show up, marginally, for a 1971 paper co-authored with Eugene Fama.

And it’s not as if Moore and Laffer are guys who may lack academic cred but have proved themselves as working analysts. On the contrary, they’re guys who can’t even cook numbers without screwing up, who have spent years telling us to get ready for soaring interest and inflation rates. But it doesn’t matter; being right is not what they’re paid for.

So in trying to understand where the Milton Friedmans of yore have gone, you want to look at the demand side. The right lacks heavyweight economists with independent reputations partly because they are hard to find, but also because it doesn’t want them. Only hacks need apply.
