The Neo-Brandeisians and Chicago School have employed different statistics to show respectively that markets are both concentrated and not concentrated, leaving Americans in the dark about who really holds corporate power. The evidence only looks contradictory due to the failure of American antitrust scholarship and regulation to understand how conglomerates collect market power across many neighboring markets, through what Paul Friederiszick calls “adjacent market takeovers.” This strategy can make firms more efficient, but it can also raise prices and weaken competition even as each individual market still looks competitive, he writes, drawing on his new paper, “The Conglomerate Power Puzzle.”

Startups in Africa rely heavily on an equity market dominated by foreign investors and founders who studied or worked outside the continent. In new research, Emanuele Colonnelli, Marcio Cruz, Mariana Pereira-Lopez, Tommaso Porzio and Chun Zhao show that this dynamic exists because local equity is expensive, the pool of local entrepreneurs seeking out funding is small, and local entrepreneurs have limited access to foreign investors.

In new research, Markus Eberhardt, Giovanni Facchini, and Valeria Rueda find that a growing share of PhD graduates from top U.S. economics programs are leaving academia, looking beyond North America, and moving into the private sector, especially towards the tech industry.

In new research, Annette Alstadsæter, Niels Johannesen, Ségal Le Guern Herry & Gabriel Zucman find that Norwegian households that become wealthy today are much less likely to adopt offshore tax evasion strategies under modern high-transparency standards. 

In new research, Tingting Song examines how FRAND principles typically used to discipline excessive or discriminatory terms in SEP licensing can be applied to data brokers in data licensing.

In new research, Blake Jackson and Ilya Strebulaev track the careers of 100,000 people working at venture capital firms in the United States to ask which investors succeed and why. They find that five percent of VCs generate 90 percent of the industry's profits, that the backgrounds investors bring with them predict who ends up in that group, and that public recognition itself opens the doors to the deals that keep them at the top.

In new research, Pranjal Drall and Andrew Granato argue that the move of private equity firms into life insurance has increased the probability that insurers will go insolvent. If they do, under an obscure system of insurance guaranty funds, the losses will spread out beyond the insolvent insurer’s creditors to other insurers and, ultimately, taxpayers. 

In new research, Andrey Simonov, Daniil Mikhailov, Ruben Enikolopov, and Ruben Durante estimate that when a 2016 law pushed Russia’s leading news aggregator Yandex to reduce its references to independent outlets, readers kept following its recommended news stories as before, reducing traffic to the excluded outlets. In response, excluded outlets changed the news they produced.

In new research, Yulia Chikish, Gregory J. Colman, Dhaval M. Dave, Brad R. Humphreys, Zachary Santamaria, and Zachary Winship find that New York City congestion pricing has reduced emergency medical services response times.

The discussion about concentration in artificial intelligence markets focuses on the least concentrated layer, the models. The chokepoint that actually threatens AI is the production of refined minerals that go into chips, data centers, and electricity production, writes Piyush Akimitsu.
