After becoming a congressional leader, a politician’s stock portfolio beats out those of peers by 47 (!!!) percentage points a year through trades timed around bills and firms that later get government contracts

www.nber.org/papers/w34524

via @florianederer.bsky.social
"Captain Gains" on Capitol Hill Shang-Jin Wei & Yifan Zhou WORKING PAPER 34524 DOI 10.3386/w34524 ISSUE DATE November 2025 Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms. 令 1 1 -9 -8 -7 -6 -5 -4 -3 -2 -1 1 2 3 4 5 7 8 9 Year Figure 2: Estimated dynamic quasi-difference-in-differences coefficient, di, of equation(3), with vertical dashed lines representing 90 percent confidence intervals. The point estimate of the year in which the lawmaker became a congressional leader (Year 0) is normalized to zero. BHAR over the 250 days following each trade is the dependent variable and calculated using the Fama-French five-factor plus momentum as the benchmark model.

New article on how international organizations frame the future of work. We see those orgas emulate the solutionist spirit of tech entrepreneurs. The Schumpeterian logic of creative distruction leaves little space for real regulation in social & labor rights. journals.sagepub.com/doi/10.1177/...

Covers a many dimensions from metatheoretical positions to typical data collected. We argue that qualitative evaluations can be strengthened and knowledge accumulation improved, if reporting follows the insights from discussions about confirmability, transferability and reflexivity.

Climate action means taxing the rich.
