Some of us are relishing what by all accounts appears to be a successful recession-resistant soft landing that was enabled, at least in part, by the management of interest rates by the Federal Reserve bank. But some of us also might be a little bummed. Pandemic stimulus led to non-trivial inflation for the first time in 30 years that had real consequences for the economy. Those issues were confronted by policy makers at the Federal Reserve bank who did their part to raise interest rates that ease us out of this inflationary window without triggering a recession. Those consecutive events, stylized facts even, appear to have left “Modern Monetary Theory” in shambles. I only interject the “appear to” qualification because MMT is a theoretic vacuum that better serves as a quasi-economic Rorschach test than falsifiable model. What are we to do without our favorite economic punching bag? What could ever unite us all, Keynesians, New Keynesians, Neoliberals/New Liberals, Monetarists, Austrians, like defending the shared empirical reality that money is real, printing money isn’t a policy free lunch, and hyperinflation is an economic tragedy to be taken deadly serious?
Well, don’t fret. There’s one more gift not everyone has opened yet. The gift that is “degrowth”. Not unlike MMT, degrowth is a little tricky to pin down. The central tenet, if there is one, is that economic growth needs to be both reversed and re-defined. That we all need to learn to live with less. As best I can tell. I guess I could link to Jason Hinkel’s book…but I don’t want to. If wikipedia is to be trusted: “The main argument of degrowth theory is that an infinite expansion of the economy is fundamentally contradictory to the finiteness of material resources on Earth”. I’m not going to spend an entire blog post dismantling this school of thought that is somehow both amusingly silly and darkly bleak in what it speaks of it’s advocates. Though spare me this one shot at an obviously wrong idea: the entire point of economic growth is that the economy can, in fact, expand forever, because new ideas (i.e. technology) and exchange both add value to the world without requiring any additional material resources (i.e. they are “non-rival”). There will never be an end to new ideas and, given those new ideas, there will never be an end to the prospective gains from exchange. Are we done here?
Of course not, don’t be silly. There are careers to be had. Keynotes to be given. Books to sell. Conferences to host. I took a shot at this on twitter, but I’m actually far more sanguine on the subject than I come across in my grim little tweet.
I’m emotionally unburdened by the attention paid to degrowth for the same reason I slept fine knowing MMT advocates were out their peddling their terrible policies. I take it as a sign of good health within the broader discipline of economics that for all of our squabbles, most of us are speaking the same language and engaging with an objective reality. Which is not to say that there aren’t knock-down, drag-out arguments about what we are observing empirically and what it means, but everyone knows what it is we are arguing about. There’s no Sokal hoax on the horizon for economics. The data is real. The policies are real. The consequences of bad decisions are very, very real.
What that means is that when a tribe forms around bad ideas and pushes them into the broader public, they have to defend those ideas. And their defense can’t elude criticism with nothing but rhetorical sleight of hand or pandering to fortified political identities for shelter from the scholarly storm. At least not for long. Whether they like it or not, their ideas will have to come into contact with reality, with formal rigor, with the data. There’s no postmodern escape hatch - to be exposed as unfasifiable is to fail at first contact. *
Yes, bad ideas can get you tenure somehwere. Or a letter published in Nature. Or a nice circuit of hosts willing to prop you up as the academic scribbler to provide the intellectual scaffolding their political movement is desperate for. But you’re not going to matter to the discipline. Your terrible, vacuous ideas will be confronted, considered, and then dismissed. No harm, no foul.
That these ideas can enter the arena at all is a sign of excellent health within the discipline. You can posit some truly wild ideas and still get them in front of the global jury of economists. You don’t have to be a Harvard economist. You don’t even have to be an economist. No position of power, no union card. The doors are open. That doesn’t mean, however, that you’re going to get a show. There’s no minimum stage time owed. Your ideas are terrible, get off the stage, next. You expected to come home from the battle either with your shield or on it, a grand warrior exposing the soft underbelly of the dismal dragon, but turned out to be just another 5 seconds of empty calories. You didn’t get what you wanted from this belch of a conflict, but the economists sitting together in the jury box did get something: a reminder that we’re all doing the best we can. We’re hissing and fighting, but only because we care. We’re trying to do it right, which is hard, and but that’s what matters the most at the end of the day. The trying.
*Sometimes what looked, to some or most, to be bad ideas turn out to, in fact, be good ideas. Great ideas, even, the kind that move the discipline forward. That’s actually the most beautiful part, that small minority of ideas that look too far afield to be taken seriously only to survive these trials by fire and become internalized in the broader mainstream of economics. Ironically, this often proves a harder test for many members of the revolutionary factions. From my own interactions, I would note that the internalization of “public choice” into the broader mainstream of economics as “political economy” proved hard for some scholars to adapt to.
