Anxiety in the face of risk
We model an ?anxious? agent as one who is more risk averse with respect to imminent risks than with respect to distant risks. Based on a utility function that captures individual subjects? behavior in experiments, we provide a tractable theory relaxing the restriction of constant risk aversion across horizons and show that it generates rich implications. We first apply the model to insurance markets and explain the high premia for short-horizon insurance. Then, we show that costly delegated portfolio management, investment advice, and withdrawal fees emerge as endogenous features and ...

Risk-Adjusted Capital Allocation and Misallocation
We develop a theory linking “misallocation,” i.e., dispersion in marginal products of capital (MPK), to macroeconomic risk. Dispersion in MPK depends on (i) heterogeneity in firm-level risk premia and (ii) the price of risk, and thus is countercyclical. We document strong empirical support for these predictions. Stock market-based measures of risk premia imply that risk considerations explain about 30% of observed MPK dispersion among US firms and rationalize a large persistent component in firm-level MPK. Risk-based MPK dispersion, although not prima facie inefficient, lowers long-run ...

Explaining the Great Moderation Exchange Rate Volatility Puzzle
In this paper, we study how the volatility of both realized and expected macroeconomic variables relates to the variation in exchange rate volatility through the prism of the Great Moderation hypothesis. We find significant heterogeneity in exchange rate trend volatility across currency pairs despite decreases in the volatility of expected future interest rate differentials and of realized yields themselves. We argue that time variation in the relationship between macroeconomic variables and exchange rates has prevented the Great Moderation in realized yield volatility from translating to a ...

High Discounts and Low Fundamental Surplus: An Equivalence Result for Unemployment Fluctuations
Ljungqvist and Sargent (2017) (LS) show that unemployment fluctuations can be understoodin terms of a quantity they call the “fundamental surplus.” However, their analysis ignores riskpremia, a force that Hall (2017) shows is important in understanding unemployment fluctuations. Weshow how the LS framework can be adapted to incorporate risk premia. We derive an equivalenceresult that relates parameters in economies with risk premia to those of an artificial economy withoutrisk premia. We show how to use properties of the artificial economy to deduce how risk premia affectunemployment ...

Risk Premia at the ZLB: A Macroeconomic Interpretation
Historically, inflation is negatively correlated with stock returns, leading investors to fear inflation. We document using a variety of measures that this association became positive in the U.S. during the 2008-2015 period. We then show how an off-the-shelf New Keynesian model can reproduce this change of association due to the binding zero lower bound (ZLB) on short-term nominal interest rates during this period: in the model, demand shocks become more important when the ZLB binds because the central bank cannot respond as effectively as when interest rates are positive. This changing ...

Uncertainty Shocks, Capital Flows, and International Risk Spillovers
Foreign investors’ changing appetite for risk-taking has been shown to be a key determinant of the global financial cycle. Such fluctuations in risk sentiment also correlate with the dynamics of uncovered interest parity (UIP) premia, capital flows, and exchange rates. To understand how these risk sentiment changes transmit across borders, we propose a two-country macroeconomic framework. Our model features cross-border holdings of risky assets by U.S. financial intermediaries that operate under financial frictions and act as global intermediaries in that they take on foreign asset risk. In ...

Wealth in the Utility Function and Consumption Inequality
Wealth in the utility function (WIU) has been increasingly used in macroeconomic modelsand this specification can be justified by a few theories such as Max Weber’s (1904-05, German; 1958) theory on “spirit of capitalism.” We incorporate the WIU into a general equilibriumconsumption-portfolio choice model to study the implications of the WIU for consumption inequality, equilibrium interest rate, and equity premium—an unexplored area in the literature.Our general equilibrium framework features recursive exponential utility, uninsurable labor risks,and multiple assets and can deliver ...

Special Repo Rates and the Cross-Section of Bond Prices: the Role of the Special Collateral Risk Premium
We estimate the joint term-structure of U.S. Treasury cash and repo rates using daily prices of all outstanding Treasury securities and corresponding special collateral (SC) repo rates. This allows us to derive a risk premium associated to the SC value of Treasuries and quantitatively link this premium to various price anomalies, such as the on-the-run premium. We show that a time-varying SC risk premium can explain between 74%?90% of the on-the-run premium, and is highly correlated with a number of other Treasury market anomalies. This suggests a commonality across these price anomalies, ...
