Banks are typically exposed to spirals between liquidity scarcity and solvency risk. We build a network model of optimizing banks featuring contagion on both sides of balance sheets: runs on short term liabilities and banks’ liquidity hoarding induce liquidity freezes; fire sale externalities and interconnected debt defaults produce asset risk. We use the model, which is calibrated to European data via simulated method of moments, to study the effects of phase-in increases of liquidity coverage ratios. Interestingly we find that the systemic risk profile of the system is not improved and might even deteriorate. Based on those insights we propose an alternative approach: differential (across banks) application of coverage ratios based on a systemic importance ranking help to mitigate the externalities and deliver a much more stable system.

Private efficiency of wage rigidity has taken centre stage in economics. Measuring its effects has proven elusive for lack of actual wage data. Using a unique confidential labour contract-level dataset matched with firm-level high-frequency asset prices, we find robust evidence that firms’ stock prices and employment fluctuate more in response to monetary policy announcements, the higher the degree of wage rigidity. Hand-collected information on the periods across renegotiations of collective bargaining agreements allow us to construct an accurate and predetermined measure of wage rigidity. We find that the amplification induced by wage rigidity is stronger for firms with high labour intensity, low profitability, and a large share of workers with more rigid contracts.

We present causal evidence on the effect of boardroom networks on firm value. We exploit a ban on interlocking directorates of Italian financial and insurance companies as exogenous variation and show that firms that lose centrality in the network experience negative abnormal returns around the announcement date. The key driver of our results is the role of boardroom connections in reducing asymmetric information. We find stronger effects for firms with fewer business partners and less experienced directors. Finally, we show that network centrality has a positive effect on directors’ compensation, providing evidence of rent sharing, and liquidity.

We conduct two survey experiments to study which information people choose to consume and how it affects their beliefs. In the first experiment, respondents choose between optimistic and pessimistic article headlines related to the COVID-19 pandemic and are then randomly shown one of the articles. Respondents with more pessimistic prior beliefs tend to prefer pessimistic headlines, providing evidence of confirmation bias. Additionally, respondents assigned to the less preferred article discount its information. The second experiment studies the role of partisan views, uncovering strong source dependence: news source revelation further distorts information acquisition, eliminating the role of priors in article choice.
