In new research, Arseniy Samsonov builds a model showing how having available to the public a multitude of media outlets and social media platforms would not help reduce misinformation from politicians. Rather, monopolistic power could enable these outlets to retain control over the narratives around the information that these politicians provide to journalists and platforms in exchange for publicity and coverage, thus reducing misinformation.

Oliver Budzinski and Victoriia Noskova discuss in their publication why merger simulations are not more widely used by competition authorities and in front of the courts to predict future effects of mergers despite advancements in availability of data, AI and computational power. The institutional setting is an essential factor for computational antitrust tools to be accepted and applied by competition authorities.

American antitrust regulators have recently taken aim at noncompete clauses. They argue that noncompetes suppress labor bargaining power and thus wages. The Italian labor market differs from its American counterpart in its rigid protections for labor, but the use of noncompetes in Italy occur at about the same rate as in the United States and shows a correlation with lower wages for workers whose noncompete clauses are unjustified because their jobs require little training and do not grant access to trade secrets. The evidence from Italy suggests that better regulation of noncompetes and informing workers of their rights is justified on the whole.

Some progressive politicians and advocates have argued that lax antitrust policies enabled the inflation surge that began in 2021 and that aggressive antitrust enforcement is crucial to combatting inflation. These assertions are misguided and misleading. Similar greedflation theories emerged during previous inflation spikes, but their promotion this time has proven counterproductive. The allure of trustbusting ideas, it seems, is starting to wane.
