Knowledge that Transforms

Ambiguity and learning about the equity premium can simultaneously explain the low fraction of financial wealth allocated to stocks over the life cycle and the stock market participation puzzle. Individuals are ambiguous about the size of the equity premium and are averse to this ambiguity, resulting in lower stock allocations over the life cycle, consistent with the data. As agents get older, they learn about the equity premium and increase their allocation to stocks. Furthermore, I find that ambiguity leads to underdiversification, home bias, lower Sharpe ratios, and higher savings. Similar results cannot be obtained by assuming higher risk aversion.

We examine the influence of outside directors’ industry experience on segment investment, segment operating performance, and firm valuation for conglomerates. Given board composition is endogenous, we instrument for the presence of industry expert directors using the supply of experienced executives near conglomerate firms’ headquarters. We find that industry expert representation on the board causes increased segment investment. Consistent with experienced directors playing favorites rather than acting as dispassionate advisors, segment profitability (firm value) is lower for segments (firms) with industry expert outside directors. We do not find analogous negative profitability or valuation effects of director experience for single-segment firms.

This paper specifies term structure dynamics by a recursive cascade of heterogeneously persistent factors. The cascade naturally orders economic shocks by their adjustment speeds, and generates smooth interest-rate curves in closed form. For a class of specifications, the number of parameters is invariant to the size of the state space, and the term structure converges to a stochastic limit as the state dimension goes to infinity. High-dimensional specifications fit observed term structure almost perfectly, match the observed low correlation between movements in different maturities, and produce stable interest-rate forecasts that outperform lower-dimensional specifications.

We examine whether sizable initial public offerings (IPOs) affect the whole market. Using a Chinese IPO sample, we find robust evidence that sizable IPOs depress the market price on not only the listing day but also the offering (subscription) day. The impact on the market is negatively correlated with IPO size on the listing day. However, this impact is largely transitory. The China Securities Regulatory Commission (CSRC) often places a moratorium on IPOs to support the market, which seems ineffective as the negative IPO effect is transitory and moratoriums are not perceived as good news.

Mutual fund managers with degrees from elite universities tend to outperform their counterparts from less elite universities. We show that the better performance of elite graduates is generated from their better connections with underwriters that facilitate allocations to underpriced initial public offerings (IPOs). Indeed, we find that the funds outperform only in months when they are connected to underwriters issuing IPOs. A strategy of buying mutual funds in months when they are connected to underwriters scheduled to issue IPOs generates significant abnormal returns, as high as 4.08% per annum in hot markets.

We examine pitfalls in the use of return-based measures of systemic risk contributions (SRCs). For both linear and nonlinear return frameworks, assuming normal and heavy-tailed distributions, we identify nonexotic cases in which a change in a bank’s systematic risk, idiosyncratic risk, size, or contagiousness increases the risk of the system but lowers the measured SRC of the bank. Assessments based on estimated SRCs could thus produce false interpretations and incentives. We also identify potentially adverse side effects: A change in a bank’s risk structure can make the measured SRC of its competitors increase more strongly than its own.

This article examines whether investors receive compensation for holding crash-sensitive stocks. We capture the crash sensitivity of stocks by their lower-tail dependence (LTD) with the market based on copulas. We find that stocks with strong LTD have higher average future returns than stocks with weak LTD. This effect cannot be explained by traditional risk factors and is different from the impact of beta, downside beta, coskewness, cokurtosis, and Kelly and Jiang’s (2014) tail risk beta. Hence, our findings are consistent with the notion that investors are crash-averse.

Whereas corporate political connections are known to enhance equity values, we demonstrate that union political activity can have the opposite effect. We examine the consequences of a recent Australian state law that restricts union political activity but does not change collective bargaining rights. In the wake of this law, the equity values of affected unionized firms significantly increase, and consistent with this market reaction, these firms are able to bargain for more favorable labor contracts than their unionized peers in other states. The evidence strongly suggests that unions use political activism to extract rents from shareholders and benefit their members.

We examine the suitability of using overnight returns to measure firm-specific investor sentiment by analyzing whether they possess characteristics expected of a sentiment measure. We document short-term overnight-return persistence, consistent with existing evidence of short-term persistence in the share demand of sentiment-influenced investors. We find that short-term persistence is stronger for harder-to-value firms, consistent with existing evidence that sentiment plays a larger role for such firms. We show that stocks with high (low) overnight returns underperform (outperform) over the longer term, consistent with prior evidence of temporary sentiment-driven mispricing. Overall, our evidence supports using overnight returns to measure firm-specific sentiment.

To “ensure depth and liquidity,” the European Central Bank intervened in sovereign debt markets through its Securities Markets Programme (SMP), providing a unique opportunity to estimate the effects of large-scale asset purchases on sovereign bond liquidity premia. From reduced-form estimates, we find robust, economically significant impact and lasting reductions in sovereign bonds’ liquidity premia in response to official purchases. We develop a search-based asset-pricing model to understand our empirical results. The theory implies that bond liquidity premia fall in response to both official purchases and rising sovereign default probabilities, as seen in the data.
