Knowledge that Transforms

We document differences in human-capital deployment between diversified and focused firms. We find that diversified firms have higher labor productivity and that they redeploy labor to industries with better prospects in response to changing opportunities. The opportunities and incentives provided in internal labor markets in turn affect the development of workers' human capital. We find that workers more frequently transition to other industries in which their diversified firms operate and with smaller wage losses compared with workers in the open market, even when they leave their original firms. Overall, internal labor markets provide a bright side to corporate diversification.

Analysts follow disproportionally firms whose fundamentals correlate more with those of their industry peers. This coverage pattern supports models of profit-maximizing information intermediaries producing preferentially information valuable in pricing more stocks. We designate highly followed firms whose fundamentals best predict those of peer firms as bellwether firms. When analysts revise a bellwether firm's earning forecast, it changes the prices of other firms significantly; however, revisions for firms that are less intensely followed do not change the prices of heavily followed firms. Unidirectional information spillovers explain how the more accurately priced stocks might exhibit more comovement.

This paper shows that housing wealth helps alleviate credit constraints for potential entrepreneurs by enabling home owners to extract equity from their property and invest it in their business. Using a large U.S. individual-level survey dataset for the 1996–2006 period, we find that a 10% increase in home equity raises the share of individuals who transition into self-employment each year from 1% to 1.07%. Our results persist when we use proxies for aggregate housing demand shocks and for the topological elasticity of housing supply to generate variation in home equity that is orthogonal to entrepreneurial choice.

Blockholders' incentives to intervene in corporate governance are weakened by free-rider problems and high costs of activism. Theory suggests activists may recoup expenses through informed trading of target firms' stock when stocks are liquid. We show that stock liquidity increases the probability of activism but does less so for potentially overvalued firms for which privately informed blockholders may have greater incentives to sell their stake than to intervene. We also document that activists accumulate more stocks in targets when stock is more liquid. We conclude that liquidity helps overcome the free-rider problem and induces activism via preactivism accumulation of target firms' shares.

Consistent with predictions from a stylized Bayesian learning model stock return volatility declines with CEO tenure in a convex manner, even for CEOs whose appointments occur for exogenous reasons. The decline is faster when there is higher uncertainty about the CEO's ability when there is more transparency about the firm's prospects, and when CEO ability is more important in value creation. We quantify the importance of uncertainty about CEO ability relative to the firm's fundamental cash flow uncertainty in contributing to stock return volatility, highlighting the importance of management in creating value.

We develop a dynamic model of investment, financing, and cash management decisions in which investment is lumpy and firms face capital supply uncertainty. We characterize optimal policies explicitly, demonstrate that smooth-pasting conditions may not guarantee optimality, and show that firms may not follow standard single barrier policies. In the model, firms with high investment costs differ in their behaviors from firms with low investment costs, financing policy does not follow a strict pecking order, and the optimal payout policy may feature several regions with both incremental and lumpy dividend payments.

This paper exploits the staggered initiation of takeover laws across countries to examine whether the threat of takeover enhances managerial discipline. We show that following the passage of takeover laws, poorly performing firms experience more frequent takeovers; the propensity to replace poorly performing CEOs increases, especially in countries with weak investor protection; and directors of targeted firms are more likely to lose board seats following corporate-control events. Our findings suggest that the threat of takeover causes managerial discipline through the incentives that the market for corporate control provides to boards to monitor managers.

Using a sample of non-U.S. firms from 43 countries, we investigate whether laws and regulations as well as votes cast by U.S. institutional investors are consistent with an effective shareholder voting process. We find that laws and regulations allow for meaningful votes to be cast, as shareholder voting is both mandatory and binding for important elections. For votes cast, we find there is greater dissent voting when investors fear expropriation. Further, greater dissent voting is associated with higher director turnover and more M&A withdrawals. Our results suggest that shareholder voting is an effective mechanism for exercising governance around the world.

We hypothesize that individual investors treat trading as a fun and exciting gambling activity, implying substitution between this activity and alternative gambling opportunities. To examine this hypothesis, we study the lottery jackpots and the trading of individual investors in Taiwan. When the jackpots exceed 500 million Taiwan dollars, the trading volume decreases between 5.2% and 9.1% among stocks preferred by individual investors and between 6.8% and 8.6% among lottery-like stocks. The decline in individual buy volume is statistically indistinct from the decline in sell volume. Large jackpots are associated with less trading in options with high sensitivity to volatility.

Many explanations for the rapid growth of the shadow banking system in the mid-2000s focus on money demand. This paper asks whether the short-term liabilities of the shadow banking system behave like money. We first present a simple model where households demand money services, which are supplied by three types of claims: deposits, Treasury bills, and asset-backed commercial paper (ABCP). The model provides predictions for the price and quantity dynamics of these claims, as well as the behavior of the banking system (in terms of issuance) and the monetary authority (in terms of open market operations). Consistent with the model, the empirical evidence suggests that the shadow banking system does respond to money demand. An extrapolation of our estimates would suggest that heightened money demand could explain up to approximately half the growth of ABCP in the mid-2000s.
