Show me the money: the monetary policy risk premium
We study how monetary policy affects the cross-section of expected stock returns. For this purpose, we create a parsimonious monetary policy exposure (MPE) index based on observable firm characteristics that are theoretically linked to how firms react to monetary policy. We find that stocks whose prices react more positively to expansionary monetary policy surprises earn lower average returns. This finding is consistent with the intuition that monetary policy is expansionary in bad economic times when the marginal value of wealth is high, and thus high MPE stocks serve as a hedge against bad ...

Spurious Inference in Unidentified Asset-Pricing Models
This paper studies some seemingly anomalous results that arise in possibly misspecified and unidentified linear asset-pricing models estimated by maximum likelihood and one-step generalized method of moments (GMM). Strikingly, when useless factors (that is, factors that are independent of the returns on the test assets) are present, the models exhibit perfect fit, as measured by the squared correlation between the model's fitted expected returns and the average realized returns, and the tests for correct model specification have asymptotic power that is equal to the nominal size. In other ...

The Private Premium in Public Bonds?
In a 2012 New York Fed study, Chenyang Wei and I find that interest rate spreads on publicly traded bonds issued by companies with privately traded equity are about 31 basis points higher on average than spreads on bonds issued by companies with publicly traded equity, even after controlling for risk and other factors. These differences are economically and statistically significant and they persist in the secondary market. We control for many factors associated with bond pricing, including risk, liquidity, and covenants. Although these controls account for some of the absolute pricing ...

Nonparametric pricing of multivariate contingent claims
In this paper, I derive and implement a nonparametric, arbitrage-free technique for multivariate contingent claim (MVCC) pricing. Using results from the method of copulas, I show that the multivariate risk-neutral density can be written as a product of marginal risk-neutral densities and a risk-neutral dependence function. I then develop a pricing technique using nonparametrically estimated marginal risk-neutral densities (based on options data) and a nonparametric dependence function (based on historical return data). By using nonparametric estimation, I avoid the pricing biases that result ...

General Aggregation of Misspecified Asset Pricing Models
This paper proposes an entropy-based approach for aggregating information from misspecified asset pricing models. The statistical paradigm is shifted away from parameter estimation of an optimally selected model to stochastic optimization based on a risk function of aggregation across models. The proposed method relaxes the perfect substitutability of the candidate models, which is implicitly embedded in the linear pooling procedures, and ensures that the aggregation weights are selected with a proper (Hellinger) distance measure that satisfies the triangle inequality. The empirical results ...

The Effect of the Federal Reserve on the Stock Market: Magnitudes, Channels and Shocks
We survey and extend work on the Federal Reserve’s effect on the stock market, focusing on three empirical findings: The effect of monetary policy surprises in a narrow window around announcements from the Federal Open Market Committee (FOMC), the pre-FOMC announcement drift, and the FOMC cycle in stock returns. We discuss the magnitude of the Fed’s impact (directional effects or effects on average stock returns), the types of shocks coming from the Fed (pure monetary policy shocks, reaction function news, or information about the Fed’s view of the economy), and the asset pricing ...

Implications of heterogeneity in preferences, beliefs and asset trading technologies for the macroeconomy
This paper analyzes and computes the equilibria of economies with large numbers of heterogeneous agents who have different asset trading technologies, preferences, and beliefs. We illustrate the value of our method by using it to evaluate the implications of these heterogeneities through several quantitative exercises.

Liquidity Premia, Price-Rent Dynamics, and Business Cycles
n the U.S. economy during the past 25 years, house prices exhibit fluctuations considerably larger than house rents, and these large fluctuations tend to move together with business cycles. We build a simple theoretical model to characterize these observations by showing the tight connection between price-rent fluctuation and the liquidity constraint faced by productive firms. After developing economic intuition for this result, we estimate a medium-scale dynamic general equilibrium model to assess the empirical importance of the role the price-rent fluctuation plays in the business cycle. ...

What we learn from China's rising shadow banking: exploring the nexus of monetary tightening and banks' role in entrusted lending
We argue that China's rising shadow banking was inextricably linked to potential balance-sheet risks in the banking system. We substantiate this argument with three didactic findings: (1) commercial banks in general were prone to engage in channeling risky entrusted loans; (2) shadow banking through entrusted lending masked small banks' exposure to balance-sheet risks; and (3) two well-intended regulations and institutional asymmetry between large and small banks combined to give small banks an incentive to exploit regulatory arbitrage by bringing off-balance-sheet risks into the balance ...

Excess volatility of exchange rates with unobservable fundamentals
We present tests of excess volatility of exchange rates that impose minimal structure on the data and do not commit to a choice of exchange rate "fundamentals." Our method builds on existing volatility tests of asset prices, combining them with a procedure that extracts unobservable fundamentals from survey-based exchange rate expectations. We apply our method to data for the three major exchange rates since 1984 and find broad evidence of excess volatility with respect to the predictions of the canonical asset-pricing model of the exchange rate with rational expectations.
