In new experimental research, Amit Zac and Michal Gal find that users who use artificial intelligence chatbots to conduct online shopping are being directed to established brands at higher prices without a clear improvement in quality.

Recent border carbon measures have relied on the theory that stricter environmental rules in rich countries push pollution-intensive production toward developing economies with weaker regulations.

In new research exploiting state-level changes in non-compete enforceability, Kate Reinmuth and Emma Rockall find that stronger non-competes have historically reduced innovation in the United States.

In new research, Martin Schmalz and Jin Xie examine how shareholder preferences influence the United States pharmaceutical industry. They find that generic-drug manufacturers sometimes harm their firms’ own value when doing so benefits shareholder portfolios, who frequently have stakes in competing brand-name firms.

China has enacted a new competition policy that seeks to boost innovation by stifling cutthroat price competition. Padding companies’ margins will enable collusion and regulatory capture rather than innovation, write Victor Jiawei Zhang and Yahui Song.

Online degrees are reshaping higher education by lowering tuition prices and reducing in-person program availability. In new research, Nano Barahona, Cauê Dobbin, and Sebastián Otero find that Brazil’s high online enrollment benefits those who need cheaper and more flexible options, but ultimately hurts young undergraduate students who are shifting away from higher-value in-person education options.
