A supply-limited economy requires supply-oriented policy, not stimulus, to grow. “Jobs” are now a cost, not a benefit. With 3.7 percent US unemployment, every worker employed on a make-work project is one not doing something more important. Regulations make housing far too costly and time-consuming to build. A coherent immigration system brings in people who work, produce, and pay taxes. We need public infrastructure, but its obscene excess cost is a rathole we can no longer afford. Tariffs that force us to overpay for things foreigners can provide better are just a drain on the economy. Policy focused on who gets what must now focus on incentives, which are the key to growth.
The cancer of stagnation
Stagnation is the quietly insidious economic cancer of our era. US growth fell by half after 2000. Europe and the UK are stagnating even more. Italy has not grown in per capita terms since 2007. Reviving long-term growth drowns any other policy, and only supply, efficiency, productivity, and incentive-oriented policy can revive long-term growth.
The view that there is unlimited demand for government debt, with buzzwords like “savings glut” or “safe asset shortage,” has equally proved false. The US, UK, and Europe seem to be able to borrow about 100 percent of GDP. More debt leads to higher interest rates, trouble borrowing, and inflation as people try to spend the extra debt rather than hold on to it as a good investment.
From now on, governments must spend money as if they have to raise taxes to pay for it, now or later. They do. Projections that debt will serenely grow to 200 percent of GDP under primary deficits that are eternally 5–10 percent of GDP will simply not happen. Worse, we have lost our fiscal capacity to react to shocks. If the $5 trillion pandemic response was more debt than people will hold and caused inflation, the $10 trillion response to the next crisis will face even more trouble.
Our left wing wants to spend trillions of dollars on cost-ineffective climate subsidies, such as massively oversize electric cars built in the US, by union labor, with US parts. Our right wing wants to spend trillions of dollars on protection and industrial subsidies in a vain (and unwise) quest to bring back 1950s manufacturing. Industrial policy will do for chips what the Jones Act (the Merchant Marine Act of 1920) did for shipping. Now that money is no longer free, we can only afford spending that actually works.
Inflation’s lessons
This inflation has two deep lessons for monetary and financial policy. First, central banks do not entirely control inflation. Inflation control needs fiscal probity as well. Second, the fiscal blowout was in part a financial bailout, including support for Treasury, municipal, and corporate debt; money market funds; airlines; and others. The central “no more bailouts” promise of the Dodd-Frank financial reform failed. In my view, another 100,000 regulations will fail again, and the only answer is the simple classic vision of equity-financed banking.
These may seem like old ideas. That’s great. Progress in economics has never come from pontificators who urge someone else to throw new ingredients in the pot—say, to “care more about people,” “add psychology,” “mix politics and economics,” incorporate “real-world” complications or “heterodox” ideas—stir, and hope that a digestible soup comes out. Progress in economics has always come from answers, patiently worked out, empirically verified, simplifying reality to actionable cause and effect statements. Economic policymaking suffers from too many pundits who rush to Washington to demand trillions of spending and untold intrusions in people’s affairs, based on half-baked stewpots of novel ideas. Economic policy should rely on well-tested notions. When economists try to supply ideas in response to political demands for the appearance of novelty, they dispense bad economics and bad politics. And what seems old to us can appear novel too. Adam Smith’s 250-year-old ideas are still news to most in politics.
