Do Wealth Taxes Significantly Curb Wealth Inequality?
Politicians and governments in the United States and elsewhere have recently proposed or implemented wealth taxes to supplement revenue and reduce wealth inequality. In a new study, Samira Marti, Isabel Z. Martínez, and Florian Scheuer show how decreases in wealth taxes led to increases in wealth inequality in Switzerland, though they find that these decreases alone are not enough to explain the magnitude of widening disparities.

Revising Guideline 6 With Evidence To Establish a Structural Inference for Input Foreclosure
Vertical merger law lacks the structural presumption of horizontal merger law, which shifts the burden from the government to the merging parties to provide evidence that a merger will not produce anticompetitive effects when it is known that the merger will substantially increase market concentration. To improve Guideline 6 of the draft Merger Guidelines concerning vertical foreclosure, Steven Salop develops a three-factor criteria with which the government antitrust agencies can show an analogous structural “inference” that shifts the burden of evidence to the merging parties.

How US Antitrust Enforcement Against Xerox Promoted Innovation by Japanese Competitors
Xerox invented modern copier technology and was so successful that its brand name became a verb. In 1972, U.S. antitrust authorities charged Xerox with monopolization and eventually ordered the licensing of all its copier-related patents. As new research by Robin Mamrak shows, this antitrust intervention promoted subsequent innovation in the copier industry, but only among Japanese competitors. Nevertheless, their innovations benefited U.S. consumers.

Revising the Merger Guidelines To Return Antitrust to a Sound Economic and Legal Foundation
The draft Merger Guidelines largely replace the consumer welfare standard of the Chicago School with the lessening of competition principle found in the 1914 Clayton Act. This shift would enable the Federal Trade Commission and Department of Justice Antitrust Division to utilize the full extent of modern economics to respond to rising concentration and its harmful effects, writes John Kwoka.

The Impact of Large Institutional Investors on Innovation Is Not as Positive as One Might Expect
In a new paper, Bing Guo, Dennis C. Hutschenreiter, David Pérez-Castrillo, and Anna Toldrà-Simats study how large institutional investors impact firm innovation. The authors find that large institutional investors encourage internal research and development but discourage firm acquisitions that would add patents and knowledge to their firms’ portfolios, hampering overall innovation.
