Should monetary policymakers raise interest rates during a boom to rein in financial excesses? We theoretically investigate this question using an aggregate demand model with asset price booms and financial speculation. In our model, monetary policy affects financial stability through its impact...

We develop a model of banking crises which Is consistent with two important features of the data: First, banking crises are usually preceded by credit booms. Second, credit booms often do not result in a crisis. That is, there are "good" booms as well as "bad" booms in the language of Gorton and...

We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

We propose a new measure of financial intermediary constraints based on how the intermediaries manage their tail risk exposures. Using data for the trading activities in the market of deep out-of-the-money S&P 500 put options, we identify periods when the variations in the net amount of trading...

This study provides a new theoretical result that a decline in the long-term interest rate can trigger a stronger investment response by market leaders relative to market followers, thereby leading to more concentrated markets, higher profits, and lower aggregate productivity growth. This...

A safe asset's real value is insulated from shocks, including declines in GDP from rare macroeconomic disasters. However, in a Lucas-tree world, the aggregate risk is given by the process for GDP and cannot be altered by the creation of safe assets. Therefore, in the equilibrium of a...

A growing literature shows that credit indicators forecast aggregate real outcomes. While researchers have proposed various explanations, the economic mechanism behind these results remains an open question. In this paper, we show that a simple, frictionless, model explains empirical findings...

A central challenge in asset pricing is the weak connection between stock returns and observable economic fundamentals. We provide evidence that this connection is stronger than previously thought. We use a modified version of the Bry-Boschan algorithm to identify long-run swings in the stock...

Central banks increasingly rely on macroprudential measures to manage the financial cycle. However, the effects of such policies on the core objectives of monetary policy to stabilise output and inflation are largely unknown. In this paper, we quantify the effects of changes in maximum...

We study the impact of monetary policy on investors' portfolio choices and asset prices. Using data on individual portfolio holdings and on mutual fund flows, we find that a low-interest-rate monetary policy increases investors' demand for high-dividend stocks and drives up their prices. The...
