Scenario severity matters nonlinearly. Higher funding costs and weaker GVA growth raise firms’ PDs at different rates and thresholds. Random Forests capture this acceleration more strongly than logit, especially as scenarios become more severe. 4/5

Linking stressed firm PDs to AnaCredit exposures creates a bank–firm network which can then build a “stressometer”. Random Forests uncover a small set of “tail banks” with higher risk under stress, showing how ML can add to central-bank & supervisory stress-testing toolkits. 5/5

The starkest finding: young workers (15–24) are hit hardest. Their participation drops after a growth shock and doesn't recover for up to 8 years – scarring that can mark an entire generation's attachment to the labour market. #EconTwitter 4/5

First causal estimate of EU participation cyclicality: a shift-share IV + local projections on EU-LFS microdata (15 countries, 114 regions, 2000–2020). Policy punchline: a stable participation rate can still hide real labour market slack. #MonetaryPolicy #EconTwitter 5/5

Why does aggregate participation look so stable? Offsetting shocks. After a downturn men's participation falls sharply. They dominate cyclical sectors like construction, while women's holds steady, partly via the "added worker effect" 3/5

The EU's aggregate labour force participation rate is remarkably resilient to recessions. Unlike in the US, where it slumps for years after a shock. But that steady headline number hides a lot. A thread on what's #HiddenInTheAggregate 2/5

Why do euro area banks transmit monetary policy differently? Authors find that bond-funded banks adjust lending rates less than money-market-funded banks, especially when they issue more fixed-rate loans. 2/2

The indirect channel decomposes into two opposing forces. Downstream: constrained customers contract intermediate input demand, reinforcing the fall in prices and output. Upstream: constrained suppliers raise prices to protect margins, partially offsetting disinflation. 4/5

The downstream demand channel dominates, so network frictions amplify rather than dampen transmission. Implication: economies with identical average leverage can respond very differently, depending on where along the supply chain frictions are concentrated. 5/5
