The cost of capital of the financial sector
Standard factor pricing models do not capture well the common time-series or cross-sectional variation in average returns of financial stocks. We propose a five-factor asset pricing model that complements the standard Fama and French (1993) three-factor model with a financial sector ROE factor (FROE) and the spread between the financial sector and the market return (SPREAD). This five-factor model helps to alleviate the pricing anomalies for financial sector stocks and also performs well for nonfinancial sector stocks compared with the Fama and French (2014) five-factor model or the Hou, Xue, ...

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 ...

Bubbles and Leverage: A Simple and Unified Approach
In this paper, we lay out a simple framework that captures much of what the theoretical literature has to say about the role of credit in systemically important asset booms and busts. In addition, we suggest ways in which to incorporate physical investment in the bubble asset as well as monetary policy.

The impact of the pandemic and the Fed’s muni program on Illinois muni yields
We estimate a simple model in which variations in Illinois daily municipal bond yields are explained by high-frequency indicators summarizing economic and public health conditions in Illinois, as well as key changes in the Federal Reserve’s Municipal Liquidity Facility (or MLF). We find that the MLF appears to have reduced Illinois muni yields by more than 200 basis points.

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 ...

Betting against beta (and gamma) using government bonds
Purportedly consistent with ?risk parity? (RP) asset allocation, recent studies document compelling ?low risk? trading strategies that exploit a persistently negative relation between Sharpe ratios (SRs) and maturity along the U.S. Treasury (UST) term structure. This paper extends this evidence on betting against beta with government bonds (BABgov) in four respects. First, out-of-sample tests suggest that excess returns may have waned somewhat recently and that the pattern seems most pronounced for USTs given data on ten other previously unexamined government bond markets. Second, BABgov ...

Discount Shock, Price-Rent Dynamics, and the Business Cycle
The price-rent ratio in commercial real estate is highly volatile, and its variation comoves with the business cycle. To account for these two facts, we develop a dynamic general equilibrium model that explicitly introduces a rental market and incorporates the liquidity constraint on an individual firm's production as a key ingredient. Our estimation identifies the discount shock as the most important factor in driving price-rent dynamics and linking the dynamics in the real estate market to those in the real economy. We illustrate the importance of the liquidity premium and endogenous total ...

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 ...

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. ...

When Do Trade Frictions Increase Liquidity?
Economists tend to assume that frictions that limit trading in financial markets reduce liquidity and lower investor welfare. In this blog I discuss a recent staff study of mine that challenges that conventional wisdom. I explain how introducing trading frictions—such as circuit breakers—that slow or halt trading in an over-the-counter market experiencing a fire sale might, paradoxically, lead to higher liquidity and investor welfare.
