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

AbstractWe document the supply chain effects of the most damaging cyberattack in history. The disruptions 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. The cyberattack also led to persisting adjustments to the supply chain network, with affected customers more likely to create new relationships with alternative suppliers and terminate those with the directly hit firms.

Exorbitant Privilege? The Bond Market Subsidy of Prospective Fallen Angels

AbstractRisky firms just above the investment-grade rating cutoff face the prospect of becoming “fallen angels'” upon a downgrade. We document that their bond issuance, especially during periods of monetary easing after the global financial crisis, enjoyed low borrowing costs relative to their non-rating based credit risk measures. This “exorbitant privilege” appears to originate in credit rating inflation, valued by yield-seeking investors. Prospective fallen angels increase their market share by acquiring firms and reducing markups, forcing their competitors to reduce employment, investment, markups, and sales, implying real effects and spillovers from their exorbitant privilege.
