Abstract: We show that “zombie credit”—cheap credit to impaired firms—has a disinflationary effect. By helping distressed firms to stay afloat, such credit creates excess production capacity, thereby putting downward pressure on product prices. Granular European data on inflation, firms, and banks confirm this mechanism. Industry-country pairs affected by a rise of zombie credit show lower firm entry and exit rates, markups, and product prices, as well as a misallocation of capital and labor, which results in lower productivity, investment, and value added. Without a rise in zombie credit, inflation in Europe would have been 0.4 percentage points higher post-2012.

Pirates without Borders: the Propagation of Cyberattacks through Firms’ Supply Chains

AbstractThis paper examines the supply chain effects of the most damaging cyberattack in history so far. The attack propagated from the directly hit firms to their customers, causing a four-fold amplification of the initial drop in profits. These losses were larger for affected customers with fewer alternative suppliers. Internal liquidity buffers and increased borrowing, mainly through bank credit lines, helped firms navigate the shock. Nonetheless, the cyberattack led to persisting adjustments to the supply chain network, with affected customers terminating relations with directly hit firms and forming new ones with alternative suppliers with a stronger cybersecurity posture.

Exorbitant Privilege? Quantitative Easing and the Bond Market Subsidy of Prospective Fallen Angels

Abstract: We document capital misallocation in the U.S. investment-grade (IG) corporate bond market, driven by quantitative easing (QE). Prospective fallen angels—risky firms just above the IG rating cutoff—enjoyed subsidized bond financing since 2009, especially when the scale of QE purchases peaked and from long-duration IG-focused investors that held more securities purchased in QE programs. The benefiting firms used this privilege to fund risky acquisitions and increase market share, exploiting the sluggish adjustment of credit ratings in downgrading after M&A, which adversely affected competitors’ employment and investment.  Eventually, these firms suffered severe downgrades at the onset of the pandemic.
