Using LLMs:
We measure how frontier research frames what is normatively at stake along the efficiency and equity dimension. We develop and validate an LLM-based measurement pipeline and apply it to 27,464 full-text journal articles from 1950 to 2021. Efficiency focused framing rises through the late 1980s, then declines as equity related framing expands after 1990, especially in applied work and policy evaluations. By 2021, papers with an equity component are about as common as papers framed purely around efficiency. President transmittal letters in the Economic Report of the President show a similar post 1990 shift toward equity, providing an external benchmark.
Here is the new NBER working paper by . I take this to be a sign of radical decline in the quality of our profession. I am all for welfare economics considering values other than efficiency. How about liberty, opportunity, and merit? Actual people, especially Americans, care about those too. The longstanding focus on equity as the relevant alternative to efficiency is one of the most blatant politicizations of economic research you will find. Most people doing it are not even aware of that, they simply take for granted that is the relevant trade-off.

The book I was reading is titled Encounters and Reflections: Conversations with Seth Benardete, here is one excerpt:
Michael: What was [Allan] Bloom like when you first met him?
Seth: He was supersensitive to people’s defects. He had antennae out, he knew exactly…
Robert: People’s weak spots?
Seth: Oh yes, it was extraordinary.
Ronna: You continued talking to Bloom often over the years, didn’t you?
Seth: Pretty often. But he was often was distracted. He got impatient if you could not say what you wanted to say in more than half a sentence.
Robert: The pressure of the sound bite.
Seth: I remember the last time he came. He was about to write the book and he asked me what I thought the Phaedrus was about. I summed it up in a sentence, and it didn’t make any impressions.
Ronna: Do you remember what the sentence was?
Seth: Something about the second speech turning into the third speech, and how this was connected to the double character of the human being. I managed to get it into one sentence, but it wasn’t something he wanted to hear.
A fun book. For all the criticisms you hear of Straussians, the few I have known I find are quite willing to speak their actual views and state of mind very clearly and directly.

This paper studies how online dating platforms have impacted marital outcomes, assortative matching, and sexually transmitted disease (STD) rates in the United States. We construct county-level measures of online dating usage using data from website-based platforms (2002-2013) and mobile app-based platforms (2017-2023). Leveraging county-level variation and an instrumental variable strategy, we show in the desktop era, a 1% increase in online dating sessions raises divorce rates by 0.50%, while in the mobile era, a 1% increase in online dating activity lowers marriage and divorce rates by 0.40% and 0.33%, respectively. We also document shifts in assortative matching. Desktop sites reduce sorting along education and employment dimensions, whereas mobile sites reduce sorting by employment, but increase sorting by race. Across both eras, we find no evidence that greater online dating usage increases average STD rates. Average effects are negative or statistically insignificant, but are positive for some subpopulations. We develop a search and matching model where technological changes impact search costs, market size, and market noise can explain our empirical findings.
That is from a new paper by Daniel Ershov, Jessica Fong, and Pinar Yildirim. Via the excellent Kevin Lewis.

1. European T-Bill sales are not an effective threat.
2. Is the 1963 The Essex hit song “Easier Said than Done” actually about a white woman who cannot bring herself to confess her love for a black man?

The great biblical scholar, Bart Ehrman, gave his retirement lecture at UNC. It’s an excellent overview on the theme of the most significant discovery in the history of biblical studies. After encomiums, Bart starts around the 13:30 mark with about 10 minutes of amusing biography. He gets into the meat of the lecture at 24:38 which is where it is cued.

Moreover, China’s expanding leadership in scientific production has not translated into a commensurate shift in global diffusion and integration. Elite research remains disproportionately focused on US topics (40% of breakthrough publications), and citations to Chinese research disproportionately come from within China rather than from other regions, even for top-tier science.
