'Buy Now, Pay Later' is Expanding Fast, and That Should Worry Everyone

1 day 16 hours ago
An anonymous reader shares a report: When Nigel Morris tells you he's worried about the economy, you listen. As industry observers know, Morris co-founded Capital One and pioneered lending to subprime borrowers, building an empire on understanding exactly how much financial stress the average American can handle. Now, as an early investor in Klarna and other buy-now-pay-later companies like Aplazo in Mexico, he's watching something that makes him deeply uncomfortable. "To see that people are using [BNPL services] to buy something as basic and fundamental as groceries," Morris told me on stage at Web Summit in Lisbon this week, "I think is a pretty clear indication that a lot of people are struggling." The statistics back up his unease. Buy-now-pay-later services have exploded to 91.5 million users in the United States, according to the financial services firm Empower, with 25% using the services to finance their groceries as of earlier this year, according to survey data released in late October by lending marketplace Lending Tree. These aren't discretionary purchases -- the designer bags and latest Apple headphones that BNPL was marketed for originally. Borrowers aren't paying it all back, either. According to Lending Tree, default rates are accelerating: 42% of BNPL users made at least one late payment in 2025, up from 39% in 2024 and 34% in 2023.

The school now holds 6.8 million shares of the exchange-traded fund, up from 1.9 million in the second quarter. The digital currency amounts to a little less than 1% of the school's $57 billion endowment. Other schools are bullish on crypto as well. Brown University reported holding $13 million of the BlackRock bitcoin ETF in the second quarter and Emory University reported holding $20 million of Grayscale's Bitcoin Mini Trust ETF as of March.

Is Video Watching Bad for Kids? The Effect of Video Watching on Children's Skills

1 day 17 hours ago
Abstract of a paper on NBER: This paper documents video consumption among school-aged children in the U.S. and explores its impact on human capital development. Video watching is common across all segments of society, yet surprisingly little is known about its developmental consequences. With a bunching identification strategy, we find that an additional hour of daily video consumption has a negative impact on children's noncognitive skills, with harmful effects on both internalizing behaviors (e.g., depression) and externalizing behaviors (e.g., social difficulties). We find a positive effect on math skills, though the effect on an aggregate measure of cognitive skills is smaller and not statistically significant. These findings are robust and largely stable across most demographics and different ways of measuring skills and video watching. We find evidence that for Hispanic children, video watching has positive effects on both cognitive and noncognitive skills -- potentially reflecting its role in supporting cultural assimilation. Interestingly, the marginal effects of video watching remain relatively stable regardless of how much time children spend on the activity, with similar incremental impacts observed among those who watch very little and those who watch for many hours.
