How is AI shaping economic research?

Does generative AI narrow or widen productivity gaps in research? We study the distributional effects of AI on research productivity in economics using evidence from three sources: NBER working-paper and publication records, text-based measures of LLM-assisted writing, and an original survey of 227 academic economists measuring AI use across research tasks. We first show that […] The post How is AI shaping economic research? appeared first on Marginal REVOLUTION. CommentsUnfortunately, I am r...

NYT debate on the rules for AI companies

Emily Bazelon was the moderator, there were five of us in the symposium. Excerpt from me: Bores: Do you think the federal government pre-empting the states is consistent with democracy? Cowen: Absolutely. We have federal laws that pre-empt state lawmaking in many other areas. Courts have upheld it many, many times. Bores: OK, but is […] The post NYT debate on the rules for AI companies appeared first on Marginal REVOLUTION. CommentsIn reply to Mike in Va. The first line is only OpenAI and . b...

Is “Who’s on First?” funny?

Well, no, it is not funny, it would be too easy to relieve the dramatic tension by having Abbott explain the actual situation to Costello. One is not wrong to call the whole thing stupid. Yet there is another reading of the skit which stands at least some chance of being funny, though it is […] The post Is “Who’s on First?” funny? appeared first on Marginal REVOLUTION.

The relative economic contribution of maternal nursing was greater in the distant past than in recent history, rivaling regionally significant industries such as pottery, glassmaking, and even the historical public sector.

Frances Lee on American elections

More likely than interference with the election is that unsuccessful office-seekers will refuse to concede, claiming their opponents cheated. Nothing is more basic to democratic legitimacy than the loser’s consent. Many feared that Mr Trump’s refusal to concede in 2020 would spread across the political system. It has not. Bright Line Watch, a research group, […] The post Frances Lee on American elections appeared first on Marginal REVOLUTION. Related StoriesI guest host an NYT podcast with Mi...

Why are cybersecurity losses not worse?

Here’s the first part of my theory: cybercriminals are not the organized geniuses we implicitly imagine. Anyone building a criminal gang has to find candidates willing to forgo more stable opportunities in the formal economy. My modeling estimated that something like 720,000 people are involved in the online criminal economy, 90% of them in scam […] The post Why are cybersecurity losses not worse? appeared first on Marginal REVOLUTION.

How central bankers spend their time

How leaders allocate their limited time and attention is an important question in economics. This paper constructs and analyzes a novel data set covering the daily calendars of three Federal Reserve Chairs, Ben Bernanke, Janet Yellen, and Jerome Powell, containing more than 20,000 calendar entries. We document several patterns. First, all Fed Chairs spend more […] The post How central bankers spend their time appeared first on Marginal REVOLUTION.
