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.
