In standard Walrasian macro-finance models, pecuniary externalities such as fire sales lead to overinvestment in illiquid assets or underprovision of liquidity. We investigate whether imperfect competition (Cournot) improves welfare through internalizing the externality and find that this is far...

The decentralized nature of blockchain markets has given rise to a complex and highly heterogeneous market structure, gaining increasing importance as traditional and decentralized (DeFi) finance become more interconnected. This paper introduces the DeFi intermediation chain and provides...

In a financial system in which balance sheets are continuously marked to market, asset price changes appear immediately as changes in net worth, eliciting responses from financial intermediaries who adjust the size of their balance sheets. We document evidence that marked-to-market leverage is...

We track 38,000 money market trades from execution to delivery and return to provide a first empirical analysis of settlement delays in financial markets. In line with predictions from recent models showing that financial claims are settled strategically, we document a tendency by lenders to...

We document the propagation effects through supply chains of the most damaging cyberattack in history and the important role of banks in mitigating its impact. Customers of directly hit firms saw reductions in revenues, profitability, and trade credit relative to similar firms. The losses were...

The policy measures taken since the financial crisis have greatly expanded the size of the Federal Reserve's balance sheet and have thus raised the level of aggregate bank reserves as well. Over the same period there has been a significant shift in the timing of payments made over the Federal...

We employ a model of leverage-induced explosive behavior in financial markets to develop a measure of financial market instability. Specifically, we derive a quantitative condition for how large levered investors can become relative to the whole market before the demand curve for securities...

Better customer service provisions by banks - such as more branches and ATMs, longer business hours, and more personalized services - help attract more core deposits and increase funding stickiness by raising depositors' switching costs and enhancing their loyalty. Funding stickiness from...

We construct a new systemic risk measure that quantifies vulnerability to fire-sale spillovers using detailed regulatory balance sheet data for U.S. commercial banks and repo market data for broker-dealers. Even for moderate shocks in normal times, fire-sale externalities can be substantial. For...

A fundamental conclusion drawn from the recent financial crisis is that the supervision and regulation of financial firms in isolation - a purely microprudential perspective - are not sufficient to maintain financial stability. Rather, a macroprudential perspective, which evaluates and responds...
