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...

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 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...

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...

The supplementary leverage ratio (SLR) rule recently imposed on the very largest U.S. banks has revived the question of whether banks sidestep such rules by shifting toward riskier, higher-yielding assets. Using difference-in-difference analysis, we find that, after the SLR was finalized in...

I study the effects of an increase in the supply of local mortgage credit on local house prices and employment by exploiting a natural experiment from Switzerland. In mid-2008, losses in U.S. security holdings triggered a migration of dissatisfied retail customers from a large, universal bank,...

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...

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...
