Insurers heavily subsidize the cost of ivermectin prescriptions for COVID, despite the lack of evidence that ivermectin is effective for COVID. In a new paper, published in JAMA, Questrom professor and TPRI co-lead Rena Conti with colleagues Kao-Ping Chua and Nora Becker (both University of Michigan) estimate that U.S. insurers may have wasted $2.5 million on these drugs in the week of August 13, 2021 alone.

This paper reports the first recent estimates of trends in the displacement of industry-leading firms. Displacement hazards rose for several decades since 1970 but have declined sharply since 2000. Using a production function-based model to explore the role of investments, acquisitions, and lobbying, we find that investments by dominant firms in intangibles, especially software, are distinctly associated with greater persistence and reduced leapfrogging.
