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...

"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...

We document a highly significant, strongly nonlinear dependence of stock and bond returns on past equity-market volatility as measured by the VIX. We propose a new estimator for the shape of the nonlinear forecasting relationship that exploits additional variation in the cross section of...

Conventional discussions of balance sheet management by nonfinancial firms take the set of positive net present value (NPV) projects as given, which in turn determines the size of the firm’s assets. The focus is on the composition of equity and debt in funding such assets. In contrast, the...

We provide an overview of data requirements necessary to monitor repurchase agreements (repos) and securities lending (sec lending) markets for the purposes of informing policymakers and researchers about firm-level and systemic risk. We start by explaining the functioning of these markets, and...

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...

Shadow banks conduct credit intermediation without direct, explicit access to public sources of liquidity and credit guarantees. Shadow banks contributed to the credit boom in the early 2000s and collapsed during the financial crisis of 2007-09. We review the rapidly growing literature on shadow...

Theories of systemic risk suggest that financial intermediaries’ balance-sheet constraints amplify fundamental shocks. We provide supporting evidence for such theories by decomposing the U.S. dollar risk premium into components associated with macroeconomic fundamentals and a component...

We derive equilibrium pricing implications from an intertemporal capital asset pricing model where the tightness of financial intermediaries’ funding constraints enters the pricing kernel. We test the resulting factor model in the cross-section of stock returns. Our empirical results show that...
