Basis‐Momentum

We introduce a return predictor related to the slope and curvature of the futures term structure: basis‐momentum. Basis‐momentum strongly outperforms benchmark characteristics in predicting commodity spot and term premiums in both the time series and the cross section. Exposure to basis‐momentum is priced among commodity‐sorted portfolios and individual commodities. We argue that basis‐momentum captures imbalances in the supply and demand of futures contracts that materialize when the market‐clearing ability of speculators and intermediaries is impaired, and that it represents compensation for priced risk. Our findings are inconsistent with alternative explanations based on storage, inventory, and hedging pressure.

The Effect of State Workers’ Compensation Program Changes on the Use of Federal Social Security Disability Insurance

In addition to traditional forms of private and public medical insurance, two other large public programs help pay for costs associated with ill health. In 2008, Workers’ Compensation (WC) insurance provided $57.6 billion in medical care and cash benefits to employees who are injured at work or contract a work‐related illness, and Social Security Disability Insurance (DI) provided $106 billion to individuals who suffer from permanent disabilities and are unable to engage in substantial gainful activity. During the 1990s, real DI outlays increased nearly 70 percent, whereas real WC cash benefit spending fell by 12 percent. There has been concern that part of this relationship between two of the nation’s largest social insurance programs may be due to individuals substituting toward DI as state WC policies tightened. We first show that this negative correlation between the national series does not hold over time within states, the level at which a causal relationship should operate. We then test for a causal effect of changes in WC enrollment on DI applications and new DI cases within states over time, using state policy (the maximum WC benefit) as an instrument for WC enrollment. Despite a strong first stage fit, we find no statistically significant evidence that WC tightening caused DI rolls to increase, although the standard errors are large enough that we cannot reject effects of substantial magnitude. We conclude it is unlikely that state WC changes were a meaningful factor in explaining the rise in DI during our study period of 1986–2001, although further study using individual level data is warranted.     

The Financial Knowledge Scale: An Application of Item Response Theory to the Assessment of Financial Literacy

Despite increasing interest in and funding for financial literacy and financial education programs in the private and public sectors, the field of financial literacy still has a major obstacle to overcome: the lack of a widely disseminated measure of financial literacy, developed through rigorous psychometric analyses. In this article, we develop such a measure, focusing specifically on financial knowledge. Using item response theory (IRT), we analyze items from three national surveys, resulting in a psychometrically sound 20‐item financial knowledge scale. By using IRT, the current analysis uses individuals' answers to inform which questions to include in the scale in the first place, rather than simply confirming relationships between these answers and other financially relevant outcomes post hoc. Widespread use of this index and the continued use of modern psychometric techniques would allow for the comparison of financial knowledge, measured consistently and reliably, across studies, populations, and programs.     

PLANNING IN AMBIGUOUS CONTEXTS: THE DILEMMA OF MEETING NEEDS FOR COMMITMENT AND DEMANDS FOR LEGITIMACY

This paper argues that ambiguity of context manifested in pressures for legitimacy and commitment affect planning processes. Ambiguity arises from multiple conflicting constituencies and the lack of direct control over resources. Using nonprofit and entrepreneurial organizations as examples of organizations facing ambiguous contexts, we examine their planning practices to develop an understanding of the relationship between commitment, legitimacy, and planning. From this analysis, we articulate a managerial dilemma: the need to use informality and vagueness to gain commitment from diverse interests, and the need to demonstrate formalization of managerial practices to acquire legitimacy from critical resource suppliers. Using elements of this dilemma, we present a new planning framework for organizations in ambiguous contexts that recognizes planning as a strategy for resource acquisition rather than a strategy for resource allocation.
