Latest / The Productivity Podcast with Fexingo: Output, Efficiency, and Long-Term Economic Growth / Why Recessions Boost Productivity Long-Term
Transcript
- Lucas: So we talk a lot on this show about what drives productivity up — better management, smarter investment, healthier workers. But there's this uncomfortable historical pattern that keeps showing up: some of the biggest productivity gains happen during or right after recessions. Luna: That sounds backwards. Recessions are when everything slows down, companies cut costs, people lose jobs — how does that make us more productive? Lucas: Right, it feels counterintuitive. But take the 2008 financial crisis. U.S. labor productivity — output per hour worked — actually jumped about 3.5 percent in 2009, right in the depths of the recession. That was the biggest one-year gain since 2002. Luna: Wait, so while unemployment was spiking past 10 percent, the people still working were getting way more efficient? Lucas: Exactly. And economists call this the 'cleansing effect' or sometimes 'creative destruction' — the idea that recessions force the weakest firms to shut down, and the stronger ones scoop up market share, invest in automation, and trim the fat. Luna: So the average productivity goes up partly because the low-productivity firms are gone. Lucas: Precisely. It's a composition effect. Think about a retailer that was barely profitable in 2007 — thin margins, outdated inventory systems. When consumer spending collapses, they go under. Meanwhile, a retailer like Walmart invests in better supply chain software, cuts labor hours per store, and emerges stronger. The survivors drag the average up. Luna: But that's a pretty brutal mechanism. It only works if a lot of businesses fail. Lucas: That's the trade-off. And there's evidence that this cleansing effect is real. Economist John Haltiwanger at the University of Maryland has studied this for decades. His work shows that during downturns, the rate of business exit spikes, and the exiting firms are disproportionately low-productivity. The ones that enter or survive are more efficient. Luna: So the recession acts like a forest fire — clears out the dead wood. Lucas: Good analogy. But the fire doesn't just burn the weak. It also changes behavior inside surviving firms. When revenue drops, management gets desperate. They finally automate that process they'd been putting off for years. They renegotiate supplier contracts. They lay off the lowest performers. All of that shows up as productivity growth. Luna: Okay, but if that were the whole story, we'd want recessions, right? Which nobody does. Lucas: Right, because the costs are enormous. The scarring effect on workers who lose jobs — long-term unemployment, lost wages, lower lifetime earnings. And there's a second, subtler problem: the productivity gains from a recession often fade after two or three years. Luna: Why would they fade? Lucas: Because the easy gains are one-time fixes. You lay off the bottom 10 percent, that's a level shift. But then you need sustained innovation to keep growing productivity. And post-recession, many firms become risk-averse. They hoard cash. They don't invest in R&D. So the initial jump plateaus. Luna: Sort of like dieting — you lose five pounds fast, then you hit a wall. Lucas: Exactly. And there's a darker possibility: if the recession is too deep or too long, it can destroy productive capacity. Not just weak firms, but good ones that run out of cash. That's what happened in Greece after 2010 — productivity collapsed because entire industries were wiped out. Luna: So the cleansing effect works best when the recession is moderate, not catastrophic. Lucas: That's the research consensus. A mild recession cleans house. A severe one burns down the house. And timing matters too. The 2009 productivity spike was partly because the recession was sharp but short — the recovery started in mid-2009. Luna: And that spike was then followed by a long period of below-trend productivity growth through the 2010s. Lucas: Right. After that initial 3.5 percent jump in 2009, productivity growth averaged barely 1 percent a year for the next decade. So the recession didn't unlock sustained improvement — it just gave a sugar rush. Luna: That lines up with something we've talked about before — the productivity slowdown since 2005. Lucas: Exactly. And that raises a question for today, June 2026. We're two and a half years past the last recession scare in late 2023. Interest rates are still elevated, but the economy has been growing slowly. If there is another downturn, can we count on a productivity bounce? Luna: I think the evidence says maybe, but not automatically. It depends on how many zombie firms are out there. Lucas: Zombie firms — companies that only survive on cheap debt — that's a big factor. In the late 2010s, a lot of weak firms stayed alive because interest rates were near zero. If rates stay high and a recession hits, those zombies die fast, which could produce a productivity spike. Luna: But could also cause a credit crunch that takes down healthy firms too? Lucas: That's the fear. The Fed is trying to walk that line. If they cut rates too early, zombies survive. If they keep rates high too long, they risk killing good companies. It's a delicate balance. Luna: Before we go deeper into the current cycle — this is exactly the kind of episode where I think some listeners get real value. If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Lucas: Yeah, completely. A one-time coffee helps keep the lights on and the research flowing. And it means we never have to run ads. So if you got something out of this, that's the way to keep it coming. Luna: Alright, back to the cleansing effect. One nuance I want to bring in: not all recessions are equal for productivity. The 2001 dot-com bust actually didn't produce a big productivity jump. Lucas: That's a great point. In 2001, productivity growth was about 2.5 percent, not terrible, but nothing like 2009. Why? Because 2001 was a mild recession, but it was also a sectoral bust — tech and telecom — not a broad-based demand collapse. Luna: So the cleansing effect is strongest when the recession hits the whole economy, not just one industry. Lucas: Exactly. Broad demand shocks force the weakest firms across all sectors to exit. Sectoral shocks just shift resources within that industry. The 2008 recession was broad — housing, finance, consumer spending, all of it. Luna: And the 2020 pandemic recession was unique too. Productivity actually surged in 2020 — about 2.6 percent — but that was mostly because low-productivity service workers lost their jobs, and high-productivity remote workers kept working. Lucas: Right, the composition effect again. But that was a weird recession — government support kept many firms alive, so there was less cleansing. Many zombie firms actually got a lifeline. Luna: So the next recession, if it comes, might be more like 2008 than 2020: less government support, more firm exits. Lucas: That's the conventional wisdom. But here's the twist: if too many firms exit, you get rising market concentration. A few big players dominate, and they have less incentive to innovate. That's actually been a concern since the 2000s — the U.S. economy has become more concentrated, and productivity growth has slowed. Luna: So the cleansing effect can backfire if it leads to oligopoly. Lucas: Exactly. There's research by Gustavo Grullon at Rice University showing that since the late 1990s, over 75 percent of U.S. industries have become more concentrated. And that correlates with less investment, lower wages, and slower productivity growth. So a recession could accelerate that trend. Luna: Which means the ideal recession is one that clears out the truly unproductive but doesn't let the survivors get too cozy. Lucas: And that's where policy matters. Antitrust enforcement, support for new business creation, investment in R&D — those can help ensure the post-recession economy is more dynamic, not just more concentrated. Luna: Let's talk about that dynamic — what do we know about business creation after recessions? Lucas: Interestingly, business formation actually spikes after deep recessions. After 2009, the number of new firms jumped significantly, especially in tech and services. But many of those new firms are small and don't have high productivity initially. It takes years for them to scale. Luna: So the productivity payoff from new firms is delayed. Lucas: Yes, and that's part of why the post-2009 productivity slowdown persisted. The new firms that started in 2010 were still small in 2015. Their productivity only started to show up later, and by then the statistical measures had already disappointed. Luna: So there's a timing mismatch between the cleansing effect and the new firm effect. Lucas: Exactly. And that's why policymakers need patience. If you judge the success of recession management by productivity in the first two years, you'll miss the longer-term picture. Luna: Alright, let's bring it back to the listener. If I'm a business owner or manager listening, what should I take away? Lucas: I'd say: don't wait for a recession to force your hand. The firms that benefit most from the cleansing effect are the ones that are already prepared — they have clean balance sheets, they've invested in technology, they have a lean operation. When the downturn comes, they're the ones buying assets cheap and grabbing market share. Luna: So the best time to prepare for a recession is before it happens. Lucas: Always. And that means looking at your own productivity metrics now. If you have processes that are clearly inefficient, fix them now — don't wait for a revenue crisis to give you permission. Because a crisis also comes with chaos and risk that makes change harder. Luna: One last thing — the human cost. We talked about scarring, but we didn't talk about how firms can avoid that. Are there examples of companies that handled layoffs in a way that preserved productivity? Lucas: Yes, and it's a tough balance. Some research suggests that firms that do systematic, performance-based layoffs — rather than across the board cuts — actually see better post-recession productivity. They keep their best people. But that requires good performance data, which many firms lack. Luna: So yet another argument for investing in better management information systems. Lucas: Right. I think the headline takeaway is this: recessions can be a productivity catalyst, but only if you come in prepared and manage the aftermath wisely. The cleansing effect is real, but it's not a free lunch. Luna: And for the broader economy, the question is whether we've learned enough from 2008 and 2020 to avoid the worst scarring while still getting the efficiency gains. Lucas: That's the open question for the next downturn. And given where we are in mid-2026, with some recession forecasts still on the table, it's worth paying attention to. Luna: Definitely. Thanks for joining us on this one. Lucas: Thanks for listening. We'll be back next time with another angle.
