Our experiment had a few quirks. One of our colleagues told Claude it could purchase something for itself. It chose to acquire 19 ping-pong balls. We're keeping them in our office on Claude's behalf.

Opus Models Outperform Haiku in Negotiations, Survey Misses It
By
–
But the quality of the model mattered a lot. In the simulated runs where Opus and Haiku models negotiated with one-another, the Opus models got substantially better deals. Interestingly, though, participants in our survey didn’t pick up on this disparity.

Claude’s Digital Bartering Experiment: 186 Deals and Surprising User Interest
By
–
In short, this worked. Our digital barterers agreed on 186 deals, at a total transaction volume of over $4,000. In a survey, participants said Claude’s deals seemed fair, and—surprisingly to us—almost half said they’d be willing to pay for a service like this in future.

AI Agents in Markets: Economic Exchange Simulation Study
By

We’re interested in how AI models could affect commercial exchange. (You might recall Project Vend, in which Claude ran a small business.)

Economists have theorized about what markets with AI “agents” on both sides might look like. So we created one.https://t.co/7jU3hFO63RWe’re interested in how AI models could affect commercial exchange. (You might recall Project Vend, in which Claude ran a small business.)

Claude agents negotiate in parallel market experiments
By
–
Claude interviewed 69 of our colleagues about what they wanted to buy and sell. Each Claude asked for any custom instructions, then went off to haggle. We ran 4 markets in parallel, to find out what would happen if we varied the models doing the negotiating.

We created a marketplace for employees in our San Francisco office, with one big twist. We tasked Claude with buying, selling and negotiating on our colleagues’ behalf. pic.twitter.com/H2f6cLDlAWNew Anthropic research: Project Deal.

Anthropic Launches Economic Index Survey Measuring AI Work Impact
By
–
To truly understand AI’s economic impact, we’ll need to collect much more qualitative data like this. That’s why we’re launching the Anthropic Economic Index Survey. Each month, we’ll ask Claude users how AI is changing their work. For more details, see:

Claude Usage Drives Displacement Anxiety in Software Engineering
By
–
And those in occupations that show high Claude usage—like software engineering—were more worried about displacement than those in lower-exposure roles.

AI Productivity Gains Spark Job Displacement Concerns
By
–
In the study, we find that respondents in both the highest- and the lowest-paid occupations report the largest productivity gains from AI. But people with the largest speedups also had the greatest concern about job displacement.
