The Equitable Economy

Jeremy Pilaar and Albert (Haotian) Wang present the weaknesses in current legislative reforms targeting pharmacy benefit managers. They suggest that lawmakers focus on reining in PBM income, limiting fees that PBMs can charge, and empowering state legislative efforts.  

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, 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.

Wealth taxes can make capital markets more efficient when they are optimally combined with lower capital gains taxes, argue Sergio Ocampo, Guttorm Schjelderup, and Floris Zoutman in new research.

Anticompetitive behavior, such as consolidation, in the health-insurance industry has allowed a small group of insurers to dominate the market. One of the main drivers of this behavior is “adverse selection,” where individuals know more about how sick they are than insurance companies do. To mitigate the risk of paying out more claims than they can cover, insurers often raise their premiums. Kellogg’s Amanda Starc and her colleague argue that, to create a truly healthy health-insurance marketplace, regulators and policymakers need a framework for rethinking the complex interactions between adverse selection and regulatory guardrails.

In new research, Benjamin Rosa finds that when states ban affirmative action, minority- and women-run businesses become smaller than other contractors and are less likely to enter the market, but are no more likely to close their businesses entirely. 

The current law and economics framework of corporate law rests on four theoretical underpinnings that restrict students’ and regulators’ understanding of the stakes of corporate law. In new research, Mariana Pargendler argues that creating corporate laws that are more attuned to social welfare will require deprogramming its dominant framework.

In recent research, Johnathan S. Hartley and Morris K. Kleiner find that occupational licensing is globally pervasive among both developed and developing nations. However, higher national licensing rates are associated with lower GDP per capita, larger informal sectors, and weaker governance scores.
