How does the presence of an AI assistant affect the collective attention of a team? In lots of nuanced ways, not all of them good. New paper: Collective Attention in Human-AI Teams arxiv.org/abs/2407.17489#

Large study shows humans can learn from AI feedback but access to AI also amplifies existing inequalities by increasing the skill gap and reduces intellectual diversity: everyone learns to specialize in the same areas arxiv.org/abs/2409.18660

Here's a cool paper estimating a model of demand for buying and playing videogames, using Steam playtime data. tl;dr: - Money is wasted bc you don't know before you buy a game how good it is - If you knew you could get 90% of your happiness at 40% the cost

With differentiated products and heterogeneous consumers, it may be hard for choices to deliver maximal welfare. We might regret choices we make, and we might miss out on products we would have enjoyed. Imke Reimers and Christoph Riedl explore this nber.org/papers/w33401

alz But we go further. We treat the deviations from proportionality as different marginal utilities of hours across games. We get very similar results for the additional hours that spending could have achieved. Joel Waldfogel Christoph Riedl

Because of missed opportunities and regrettable purchases, differentiated product choices can have large welfare costs, which is quantified with post-purchase video game usage data, from Imke Reimers, Christoph Riedl, and Joel Waldfogel nber.org/papers/w33401

New paper: Language models have “universal” concept representation – but can they capture cultural nuance? 🌏 If someone from Japan asks an LLM what color a pumpkin is, will it correctly say green (as they are in Japan)? Or does cultural nuance require more than just language?
