A Model of Shadow Banking

We present a model of shadow banking in which banks originate and trade loans, assemble them into diversified portfolios, and finance these portfolios externally with riskless debt. In this model: outside investor wealth drives the demand for riskless debt and indirectly for securitization, bank assets and leverage move together, banks become interconnected through markets, and banks increase their exposure to systematic risk as they reduce idiosyncratic risk through diversification. The shadow banking system is stable and welfare improving under rational expectations, but vulnerable to crises and liquidity dry‐ups when investors neglect tail risks.     

Disclosure and Recognition Requirements: Corporate Investment Decisions with Externalities*

This paper examines the effects of disclosure and recognition requirements on investment decisions when shareholders have limited liability. Firms' investment projects have either high initial pollution prevention costs or high subsequent clean‐up costs, and their liability for clean‐up costs may be either individual or joint and several. Even with individual liability for clean‐up costs, shareholders' limited liability creates an incentive to select the latter project type and to impose costs on the rest of the economy. This tendency is exacerbated when clean‐up liability is joint and several. We show that a disclosure requirement cannot have an unambiguous effect on the selection of the “cleaner” project. However, an accrual requirement, together with an accounting‐based dividend restriction, is shown to promote choice of the project that imposes lower expected costs on the rest of the economy. Moreover, we find that it is possible for a recognition requirement to have a greater impact in a joint‐and‐several liability regime than in an individual liability regime.     

Does Calculating Retirement Needs Boost Retirement Savings?

Calculating retirement savings needs is often viewed as an essential first step in retirement planning. Yet, little empirical evidence exists to support the value of this activity. This case study examines the connection between calculating retirement savings needs and retirement savings through analysis of an online survey of benefits‐eligible employees at a large Mountain West university. Controlling for a variety of possible covariates, and using an instrumental variable approach, the case study shows that having estimated a retirement savings target increases self‐reported retirement savings. The results provide support for financial educators and planners in their efforts to encourage people to estimate their retirement needs early in the retirement planning process.     

Why Do Large Firms' Prices Anticipate Earnings Earlier than Small Firms' Prices?*

This paper presents evidence that the positive association between firm size and price leads of earnings is not solely a function of private search incentives for firm‐specific information. Specifically, we find that small‐firm prices also lag large‐firm prices with respect to industry‐wide information. Our empirical analysis extends Collins, Kothari, and Rayburn 1987 and Freeman 1987, who document that security‐price leads of earnings are positively associated with market capitalization. In particular, we examine the association between firm size and the timing of security returns for two components of annual earnings changes: the average change for a firm's industry and the firm's idiosyncratic change. We find that large firms' prices have a longer lead than small firms' prices with respect to both components. Large firms' early lead on industry‐wide earnings suggests that returns of large firms predict returns of same‐industry small firms. To test this implication, we construct a portfolio of long (short) positions in small firms when the prior month's returns of large firms in their industry are above (below) average for large firms in other industries. This zero investment portfolio earns 4.5 percent over 12 months.
