Social media feeds today are optimized for engagement, often leading to misalignment between users' intentions and technology use.

In a new paper, we introduce Bonsai, a tool to create feeds based on stated preferences, rather than predicted engagement.

(To be clear, this is not a counterfactual. Absent the AI boom we would probably have lower interest rates & electricity prices, thus some additional growth in other sectors. In very rough terms that could maybe make up about half of what we got from the AI boom.)

It looks like he didn't share it on Bluesky, so I will. @afinetheorem.bsky.social has written an excellent review article covering 7 recent books on the economics of AI that serves as an excellent overview of this topic. Highly recommended!

New HBR piece on “workslop”: companies are rolling out genAI and employees are using it, but value isn’t showing up. AI-led processes nearly doubled; workplace use doubled since 2023; yet 95% of orgs see no measurable ROI.

AI-Generated “Workslop” Is Destroying Productivity
Despite a surge in generative AI use across workplaces, most companies are seeing little measurable ROI. One possible reason is because AI tools are being used to produce “workslop”—content that appea...

Restricting visas doesn’t lead to hiring non-immigrants—it leads to hiring foreigners. For every H-1B visa rejection, multinationals add ~0.4–0.9 foreign employees, especially in R&D hubs like India, China, and Canada.

How Do Restrictions on High-Skilled
Immigration Affect Offshoring?
Evidence from the H-1B Program
Britta Glennon
WORKING PAPER 27538
DOI 10.3386/w27538
ISSUE DATE July 2020
REVISION DATE February
2023
Highly-skilled workers are not only a crucial and relatively scarce inputs into firms' productive and innovative processes, but are also a critical resource determining competitive advantage. An increasingly high proportion of these workers in the US were born abroad and permitted to work on skilled worker visas. How do multinational firms respond when artificial constraints, namely policies restricting skilled immigration, are placed on their ability to hire scarce human capital? This paper combines visa microdata and comprehensive data on US multinational firm activity to demonstrate that firms respond to restrictions on H-1B immigration by increasing foreign affiliate employment at the intensive and extensive margins, particularly in China, India, and Canada. The most impacted jobs were R&D-intensive ones, but there is some evidence that non-R&D employment was also affected. The paper highlights a means by which firms can circumvent constraining policies and mitigate country-level risk, but it also suggests that, for the average MNC, this means is imperfect; for every visa rejection, they hire 0.4 employees abroad. The most globalized MNCs are the most likely to respond to these restrictions by offshoring, highlighting that firm capabilities—in the form of prior internationalization-shape the decision and ability to offshore in response to skilled immigration restrictions; indeed, these firms hire 0.9 employees abroad for every visa rejection. More broadly, the paper provides evidence of a push factor for internationalizing knowledge activity: artificial constraints on resources result in firms circumventing restrictive policies in ways that may not be anticipated by policy makers.

This paper argues that if AGI can be achieved it will automate critical types of work. Growth then rides on compute; wages equal the compute needed to replicate work; labour’s share trends toward zero. The question: who owns the compute—and who shares the gains? conference.nber.org/conf_papers/...

Demand for human-generated, trust-certified internet content is skyrocketing.

There is a major business opportunity, in *every* country, for media firms to meet this rising demand with innovation.

To make sure AI serves workers we need bold action: corporate regulation, worker voice, and sectoral bargaining.
