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, Irfan Saleem and Giray Gozgor show that the “pollution haven” mechanism is neither automatic nor uniform across industries. Evidence is mixed, often small in magnitude, and highly sensitive to how we measure regulation, model trade, and account for industry mobility.

The European Union can pursue financial sovereignty through the digital euro, but sovereignty over money doesn't mean sovereignty over the markets that form around it, writes Jeff Alvares.

If confirmed, Kevin Warsh would be the latest Federal Reserve chair whose career took place primarily on Wall Street rather than in academia. The ascent of Wall Street veterans in the Fed risks skewing monetary policy to favor large investors and the wealthiest, writes Franny Philos Sophia.

In new research, Michele Fioretti, Victor Saint-Jean, and Simon Smith show that NGO activism follows a clear economic logic: when NGOs lack visibility, stakeholders do not view them as credible, forcing them to rely on high-profile campaigns during annual shareholder meetings. However, these actions generate attention but rarely influence decisions. As NGOs gain recognition, they can campaign earlier, when votes are still open, and meaningfully sway shareholders and change corporate behavior.

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. These declines are driven by sharp drops in inventor mobility and knowledge spillovers, especially in young, high-growth sectors.
