Does the presence of arbitrageurs decrease equilibrium asset price volatility? I study an economy with arbitrageurs, informed investors, and noise traders. Arbitrageurs face a trade-off between arbitrage and inference: they would like to buy assets in response to temporary price declines (the...

The evolution of risk management has resulted from the interplay of financial crises, risk management practices, and regulatory actions. In the 1970s, research lay the intellectual foundations for the risk management practices that were systematically implemented in the 1980s as bond trading...

This paper explores financial stability policies for the shadow banking system. I tie policy options to economic mechanisms for shadow banking that have been documented in the literature. I then illustrate the role of shadow bank policies using three examples: agency mortgage real estate...

One year after passage of the Dodd-Frank Act (DFA), regulators proposed several of the rules required for its implementation. In this paper, I discuss some aspects of proposed DFA rules in light of shadow banking. The topics are risk-retention rules for securitized products and the impact of...

Pierret (2015) presents empirical analysis of the solvency-liquidity nexus for the banking system, documenting that a shock to the level of banks' solvency risk is followed by lower short-term debt. Conversely, higher short-term debt Granger-causes higher solvency risk. These results point...

The COVID-19 pandemic is causing an unprecedented worldwide economic contraction, leading central banks to reduce interest rates to historically low levels and making unconventional monetary policies-including 'low for long' interest rates and asset purchases-increasingly common. Arguably,...

"When risk-factor loadings are time-varying and unobservable, investors are forced to form beliefs about the levels of their loadings. The learning process involved in forming these beliefs has normative implications for asset-pricing tests. This paper develops an equilibrium model of learning...

The macro risk premium measures the threshold return for real activity that receives funding from savers. We base our argument in this paper on the relationship between the macro risk premium and the growth of financial intermediaries’ balance sheets. The spare capacity of their balance sheets...

We reconsider the role of financial intermediaries in monetary economics. We explore the hypothesis that financial intermediaries drive the business cycle by way of their role in determining the price of risk. In this framework, balance sheet quantities emerge as a key indicator of risk appetite...

Central banks have a variety of tools for implementing monetary policy, but the tool that has received the most attention in the literature has been the overnight interest rate. The financial crisis that erupted in the summer of 2007 has refocused attention on other channels of monetary policy,...
