Time-Varying Beta and the Value Premium

Journal of Financial and Quantitative Analysis 2017 52(4), 1551-1576
We model conditional market beta and alpha as flexible functions of state variables identified via a formal variable-selection procedure. In the post-1963 sample, the beta of the value premium comoves strongly with unemployment, inflation, and the price–earnings ratio in a countercyclical manner. We also uncover a novel nonlinear dependence of alpha on business conditions: It falls sharply and even becomes negative during severe economic downturns but is positive and flat otherwise. The conditional capital asset pricing model (CAPM) performs better than the unconditional CAPM, but this does not fully explain the value premium. Our findings are consistent with a conditional CAPM with rare disasters.

Transforming the management and governance of private family firms: The role of venture capital

Journal of Corporate Finance 2021 66, 101828
We analyze the role of venture capitalists (VCs) in transforming the management and governance of China's private family firms. We show, causally, that VC-backed family firms are more likely than non-VC backed family firms to experience departures of family members from top management positions and decreases in the separation between family control rights and cash-flow rights; these effects are stronger when VCs have greater equity ownership or board representation. We show that these changes in top management and governance in family firms are associated with higher IPO firm valuations and better post-IPO long run stock returns.

Information spillover and cross-predictability of currency returns: An analysis via Machine Learning

Journal of Banking & Finance 2024 169, 107313
This paper documents significant cross-return predictability of news variables, derived from textual analysis of news articles, for a broad cross-section of currencies. By employing forecasts based on the Least Absolute Shrinkage and Selection Operator (LASSO) that incorporate both news variables and forward discounts, we develop a notably profitable trading strategy. This strategy proves robust against transaction costs, risk adjustments, and controls for currency characteristics. Further analyses indicate that both risks and market frictions contribute to the profitability of the trading strategy, highlighting the crucial role of news in financial markets.

Funding liquidity shocks in a quasi-experiment: Evidence from the CDS Big Bang

Journal of Financial Economics 2021 139(2), 545-560
We use the advent of new credit default swap (CDS) trading conventions in April 2009—the CDS Big Bang—to study how a shock to funding liquidity impacts market liquidity. After the Big Bang, traders are required to pay upfront fees to execute CDS transactions, with the size of the fees depending on the level of CDS spreads. While CDS bid-ask spreads decline in aggregate after the Big Bang, they do so less for contracts that require larger fees. Furthermore, the funding effect is stronger for smaller and riskier firms and for noncentrally cleared contracts. The effect also becomes stronger after Deutsche Bank's exit.

Are Liquidity and Information Risks Priced in the Treasury Bond Market?

Journal of Finance 2009 64(1), 467-503
ABSTRACT We provide a comprehensive empirical analysis of the effects of liquidity and information risks on expected returns of Treasury bonds. We focus on the systematic liquidity risk of Pastor and Stambaugh as opposed to the traditional microstructure‐based measures of liquidity. Information risk is measured by the probability of information‐based trading (PIN). We document a strong positive relation between expected Treasury returns and liquidity and information risks, controlling for the effects of other systematic risk factors and bond characteristics. This relation is robust to many empirical specifications and a wide variety of traditional liquidity and informed trading proxies.
