Abstract: To safeguard its technological leadership, the U.S. has restricted domestic suppliers from exporting specific cutting-edge technologies to selected Chinese firms. Domestic firms affected by these export controls halt sales to Chinese customers, as intended, but struggle to establish new relations with alternative customers domestically or in politically aligned regions. As a result, domestic suppliers experience a $130 billion decline in market capitalization, along with reductions in profitability, employment, and bank lending. We also show how Chinese firms strategically respond to export controls. Overall, export controls impose significant costs on domestic firms producing the very technologies these policies intend to protect.

Abstract: We show that banks “extended-and-pretended” their impaired CRE mortgages in the post-pandemic period to avoid writing off their capital, leading to credit misallocation and a buildup of financial fragility. We detect this behavior using loan-level supervisory data on maturity extensions, bank assessment of credit risk, and realized defaults for loans to property owners and REITs. Extend-and-pretend crowds out new credit provision, leading to a 4.8–5.3% drop in CRE mortgage origination since 2022:Q1 and fuels the amount of CRE mortgages maturing in the near term. As of 2023:Q4, this “maturity wall” represents 27% of bank capital.

Abstract: We find that banks differ in their propensity to lend to minorities based on their stakeholders’ aversion to inequality. Using mortgage application data collected under the Home Mortgage Disclosure Act, we document a large and persistent cross-sectional variation in banks’ propensity to lend to minorities. Inequality-averse banks have a higher propensity to lend to borrowers in high-minority areas and, within census tracts, to non-white borrowers compared to other banks. This higher propensity (i) is not explained by selection of applicants, (ii) allows these banks to retain and attract their inequality-averse stakeholders, and (iii) does not predict worse ex-post loan performance.

Abstract: We document how the interaction of supply chain pressures, heightened household inflation expectations, and firm pricing power contributed to the pandemic-era surge in consumer price inflation in the euro area. Initially, supply chain pressures increased inflation, especially in manufacturing sectors, through a cost-push channel and raised inflation expectations. Subsequently, the cost-push channel intensified as firms with high pricing power increased product markups in sectors witnessing high demand, including in services sectors that were initially not exposed to supply chain constraints. Eventually, even though supply chain pressures eased, these firms were able to further increase markups due to the stickiness of inflation expectations. The resulting persistent impact on inflation suggests supply-side impulses can generalize into broad-based inflation via an interaction of household expectations and firm pricing power.

Abstract: Are carbon emissions priced in equity markets? The literature is split, but most research finds carbon emissions intensity, a measure targeted by ESG investors, is not priced. We show that: (i) most existing empirical tests suffer from measurement error and omitted variable bias, and (ii) if emissions intensity is priced, stock returns depend on expected emissions intensity and the product of the innovation in emissions intensity and the price-dividend ratio. Based on these new predictions, our empirical results confirm emissions intensity is priced, but the magnitude is largely driven by a few industries characterized by the presence of “super emitters.”
