After almost 10 years of work corporateownershipdata.com now makes available all publicly available ownership records of 7,156 publicly traded firms, not just the S&P 500, including dual-class shares.

Super interesting paper on U.S. elites, 1850–1950. The top tail of U.S. asset owners experiences rapid turnover. 70% of individuals in the top 1% are no longer there 10 or 20 years later.

Super interesting! "How Knowledge Crosses Borders: Evidence from Semiconductor Manufacturing" by Pinelopi Koujianou Goldberg, Réka Juhász, Giulia Lo Forte, and Jeff Thurk. "We show that cross-border learning is an important feature of modern semiconductor manufacturing and that several important channels - such as knowledge sharing along global supply chains, the movement of engineers within multinational firms, and foreign direct investment - operate through market mechanisms rather than anonymous technological spillovers. These findings have significant policy implications. When cross-border learning is mediated by purposeful economic relationships, access to frontier knowledge is neither automatic nor guaranteed. Firms and governments can facilitate - or restrict - the international diffusion of technology, implying that policies to foster domestic technological upgrading are likely to be most effective when coupled with continued access to global sources of frontier knowledge." bpb-us-w2.wpmucdn.com/campus…

Long contracts signed in booms make markets thinner and slower to adjust. In the containership leasing market, this "contracting externality" leads to major capital misallocation, especially after crashes, from Maria Garcia-Osipenko, Nicholas Vreugdenhil, and Nahim B. Zahur nber.org/papers/w35821

Why has nobody taught the fruit fly brain to love :’(
I gave the fly brain $100 to trade bitcoin. Dopamine neurons are stimulated when the fly makes profit. Neuron activity controls buy/sell decisions and makes trades on coinbase. Will the fly get rich?

We propose an algorithm for building efficient recentered IVs. While simulated IVs for Medicaid eligibility discard individual variation as non-random, our recentered IVs preserve it and deliver much more precise estimates. econometricsociety.org/publi…
