In new research, Christos Makridis and Andrew Johnston find that industries exposed to generative AI are seeing an increase in production, employment, and wages. However, the majority of AI-driven revenue growth is channelled back to capital as profits, rather than to workers.

In new research, Ido Baum, Leszek Balcerowicz, Jakub Karnowski and Andrzej Rzońca assess how Poland achieved economic growth with a populist government. They argue that the economic success is misleading and Poland’s leading party passed harmful policies that affect the country’s long-term growth opportunities. 

In new research, Louis Pape and Michelangelo Rossi find that the European Union’s Digital Markets Act’s prohibition on self-preferencing had little effect on the popularity of Google Maps relative to competitors. User preference for the incumbent service appears to outweigh frictional barriers to access.

In new research in collaboration with Color of Change, Dante Donati and Lena Song find that comments on social media posts help drive platform engagement for organizations. However, comment sections are often populated by a vocal minority, and adversarial comments from them come with reduced off-platform support for the original posters.

In new research, Joel Dodge and Ganesh Sitaraman argue that a comprehensive industrial policy to secure American supply chains and ensure access to essential goods should incorporate the deployment of public factories.

In new research, Michele Fioretti and Alessandro Iaria discuss how a landmark Norwegian court ruling shows how constitutional constraints on the government’s ability to retroactively change contracts can encourage private innovation and reshape entire industries.

In new research, Marco Battaglini, Valerio Leone Sciabolazza, Mengwei Lin and Eleonora Patacchini study how the deaths of large donors change candidates’ electoral results and congressional activity in a new measure of donors’ influence in American politics.

Victor Jiawei Zhang revisits the 2025 United States ban on TikTok and explores how it represented a case study of how the government led users to act collectively to override network effects and introduce competition to the digital market. The case study highlights research from his new article, “Digital Antitrust Collectivism,” where he explores the possibility that users’ collective power can invigorate digital market competition.

Across three studies, Jana Friedrichsen, Julia Schwarz, and Michel Clement explore how generative AI will change the music industry. They find that while consumers enjoy and even prefer AI-generated music, preferences shift upon learning that the song was AI-generated.

In new research, Jongkwan Lee, Giovanni Peri, and Hee-Seung Yang assess the effects of a sudden reduction in immigrant workers in South Korea. They find that migrant workers were not easily replaceable by natives, resulting in operational disruptions and firm closures.
