Between 2010 and 2020, the U.S. coal industry experienced a 50% drop in production, employment, and active mines, driven by regulatory factors and technological innovation in alternative energy sources. We study the impact of this energy transition on household employment, wages, migration, and home ownership in affected communities. Compared to non-coal-producing, resource-rich counties, coal-producing counties experience 6% and 4% drops in employment and wages, respectively, during this period. Economic mobility and access to banking services significantly moderate these real effects, suggesting a potential role for finance to shape the industrial and economic changes associated with climate transitions.

The U.S. banking sector had nearly 70% fewer banks in 2022 relative to 1989, primarily because of mergers. We develop a methodology to estimate cross-market spillover effects of bank mergers and test whether the operations of incumbents facing consolidating competitors in one market are affected in other markets. We find that nonmerging banks within a market that are one standard deviation more exposed to mergers in other markets increase deposits by 2.1% relative to their less exposed competitors. Our methodology may be applied elsewhere to assess the aggregate impacts of industry consolidation and illustrates challenges with product-based or geographic market definitions.
