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.

In new research, Enghin Atalay, Alan Sorensen, Christopher Sullivan, and Wanjia Zhu find that mergers and acquisitions often lead to the merged firm offering less product variety than when the two firms operated pre-merger.

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.

In new research, Cyril Hédoin and Alexandre Chirat use the rational-choice theory of economist Anthony Downs to explain how populism rationally arises to challenge established institutions of liberal democracy.

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.

Simcha Barkai describes the results of new research on the impact of antitrust on U.S. economic activity with co-authors Tania Babina, Jessica Jeffers, Ezra Karger, and Ekaterina Volkova. Enforcement, they find, increases the level of economic activity.

In new research, Mariana Pargendler, Maria Luiza Mesquita, and Lucas Víspico study how antitrust authorities in the Global South have used family ties to define business enterprises and analyze mergers and acquisitions for possibly anticompetitive behavior.

In new research, Francesco Barilari and Diego Zambiasi study how President Ronald Reagan and George H.W. Bush’s rhetoric on the War on Drugs while on the campaign trail, particularly targeting crack cocaine abuse, was enough to alter policing policy. Specifically, the authors find that increased rhetoric led to an increase in arrests of Black Americans. Their study contributes to a literature on the material impact that political rhetoric can have on policing and public policy.

With slightly more than one year until the United States presidential election, electoral campaigns are about to ramp up. These quadrennial elections, like so many others in democracies worldwide, will mobilize thousands of campaign workers who play an integral role in shaping candidates’ electoral performance. Yet, little is known about these workers and how the experience of working in a campaign shapes their professional lives. This column describes the findings from a new study on the career trajectories of campaign labor in Brazil, showing that connections forged on a campaign provide qualified workers with better employment and earnings opportunities. This article was originally published in VoxEU.

In new research, Sabien Dobbelaere, Grace McCormack, Daniel Prinz, and Sándor Sóvágó find that mergers negatively impact labor market outcomes. Mergers result in job losses, and the earnings of workers who lose their jobs don’t recover for several years on average. The authors find these negative consequences are more likely attributable to the restructuring of labor forces than subsequent firm market power.
