🎣 The Executive Hook

The "One Big Idea": Free trade surges like China's 2001 WTO entry detonate regional manufacturing bombs, obliterating over 1M jobs in localized clusters, where workers fail to relocate or reskill due to skill specificity and weak outside options—leading to permanent labor force exit rather than seamless reallocation. Places rebound via low-wage service influx and demographic shifts (e.g., immigrants, women), but original prime-age men endure scarring depressions with elevated disability claims and non-participation. Consensus models ignored employment drops, mistaking aggregate GDP gains for equitable adjustment.
Why It Matters: In a high-tariff era amid Fed tightening and AI-driven productivity waves, this reveals why deindustrialized U.S. heartlands fuel protectionism—executives must anticipate policy rever

With the year coming to a close, we're sharing our most popular Planet Money bonus episode of 2025!

As U.S. trade with China exploded in the early 2000's, American manufacturing began to shrivel. Those workers struggled to adapt and find new jobs. It ran counter to how mainstream economics at the time viewed free trade ... that it would be a clear win for the U.S. Greg Rosalsky talks with David Autor about why economists got free trade with China so wrong.

Autor, an MIT economics professor, and his colleagues published a series of eye-opening studies over the last 15 years or so that brought to light the costs of U.S. trade with China. We also hear Autor's thoughts on the role of tariffs and get an update on his research. With better, more precise data, Autor says we have a more nuanced and "bleaker" picture of what happened to these manufacturing workers.
