What Drives Bank Peformance?
Focusing on some key metrics of bank performance, such as revenues and loan charge-off rates, we estimate the fraction of the observed variation in these metrics that can be attributed to changes in economic conditions. Macroeconomic factors can explain the preponderance of the fluctuations in charge-off rates. By contrast, bank-specific, idiosyncratic factors account for a sizable share of the variation in bank revenues. These results point to importance of bank-specific business models as a driver of performance.

A Static Capital Buffer is Hard To Beat
In a model with endogenous risk-taking, deposit insurance and limited liability may lead banks to make risky loans that are socially inefficient. Capital requirements can prevent excessive risk-taking at the cost of reducing liquidity-producing bank deposits. A policy that sets capital requirements just high enough to prevent excessive risktaking will move capital requirements pro-, counter-, or a-cyclically depending on the shock source. However, such a policy requires full knowledge of all the shocks hitting the economy and is not implementable. Simple rules that respond to cyclical ...

Inflation dynamics
Gali and Gertler (1999) are the first to find that the baseline sticky price model fits the U.S. data well. I examine the robustness of their estimates along two dimensions. First, I show that their IV estimates are not robust to an alternative normalization of the moment condition being estimated. However, when using a Monte Carlo study to investigate small-sample properties, I show that the normalization chosen by Gali and Gertler (1999) yields a superior estimator. Second, I check whether or not the proportion of backward-looking firms augmenting the baseline model to fit the data is ...

International competition and inflation: a New Keynesian perspective
We develop and estimate an open economy New Keynesian Phillips curve (NKPC) in which variable demand elasticities give rise to changes in desired markups in response to changes in competitive pressure from abroad. A parametric restriction on our specification yields the standard NKPC, in which the elasticity is constant, and there is no role for foreign competition to influence domestic inflation. By comparing the unrestricted and restricted specifications, we provide evidence that foreign competition plays an important role in accounting for the behavior of inflation in the traded goods ...

Optimal Dynamic Capital Requirements and Implementable Capital Buffer Rules
We build a quantitatively relevant macroeconomic model with endogenous risk-taking. In our model, deposit insurance and limited liability can lead banks to make risky loans that are socially inefficient. This excessive risk-taking can be triggered by aggregate or sectoral shocks that reduce the return on safer loans. Excessive risk-taking can be avoided by raising bank capital requirements, but unnecessarily tight requirements lower welfare by limiting liquidity producing bank deposits. Consequently, optimal capital requirements are dynamic (or state contingent). We provide examples in which ...

Oil shocks and the zero bound on nominal interest rates
Beginning in 2009, in many advanced economies, policy rates reached their zero lower bound (ZLB). Almost at the same time, oil prices started rising again. We analyze how the ZLB affects the propagation of oil shocks. As these shocks move inflation and output in opposite directions, their effects on economic activity are cushioned when monetary policy is constrained. The burst of inflation from an oil price increase lowers real interest rates at the ZLB and stimulates the interest-sensitive component of GDP, offsetting the usual contractionary effects. In fact, if the increase in oil prices ...

Lessons from the Co-movement of Inflation around the World
The aftermath of the COVID-19 pandemic saw a surge in inflation around the world, reflecting rapid increases in the demand for goods, strained supply chains, tight labor markets, and sharp hikes in commodity prices exacerbated by the Russian war on Ukraine. As illustrated in figure 1, this inflation surge was synchronized across advanced and emerging economies, not only for total inflation but also for its core component.

Macroeconomic Policy Games
Strategic interactions between policymakers arise whenever each policymaker has distinct objectives. Deviating from full cooperation can result in large welfare losses. To facilitate the study of strategic interactions, we develop a toolbox that characterizes the welfare-maximizing cooperative Ramsey policies under full commitment and open-loop Nash games. Two examples for the use of our toolbox offer some novel results. The first example revisits the case of monetary policy coordination in a two-country model to confirm that our approach replicates well-known results in the literature and ...

The Information Content of Stress Test Announcements
We exploit institutional features of the U.S. banking stress tests to disentangle different types of information garnered by market participants when the stress test results are released. By examining the reaction of different asset prices, we find evidence that market participants value the stress test announcements not only for the information on possible future capital distributions but also for the signals about bank resilience. These results back the use of stress tests by central banks to inform the broader public about the soundness of the banking system.
