Erik Voeten — Green Industrial Policy & Geopolitics of Investment in Critical Minerals and Batteries

The U.S. and Europe view China’s dominance in critical minerals and the battery supply chain as a security threat, which motivates increasingly aggressive coercive policies. Yet, can industrial policies help diversify global supply chains through incentives? We study this question in the context of the U.S. Inflation Reduction Act (IRA) of 2022, which offered incentives for battery manufacturers to reduce reliance on China and gave preferential treatment to countries with a Free Trade Agreement (FTA). We argue that industrial policies can be effective but that they face strong credibility and distributive challenges. We first use an event study to show that major Chinese battery manufacturers and critical mineral companies suffered significant negative abnormal returns compared to firms in FTA countries in the days following the surprise IRA announcement. A difference-in-differences analysis of data on greenfield and brownfield investments then shows that since the IRA took effect, FDI in countries with an IRA-compliant FTA have increased significantly compared to those geopolitical allies of the US without an FTA. This investment effect is statistically and substantively significant, and driven entirely by non-Chinese investors. However, the effect disappeared in the second half of 2024 when the election of President Trump, who vowed to dismantle the IRA, became more likely. These findings thus demonstrate both the potential and limits of industrial policy as a foreign policy tool. Erik Voeten is the Peter F.
