Leveraging FDA Health Claims

Although past research has investigated different aspects of various health claims, relatively little effort has been directed toward synthesizing the reasons why some Food and Drug Administration (FDA) health claims are more successful than others. After outlining two necessary conditions for a health claim's success, currently approved FDA health claims are examined to explain both the diet–health relationship and its effect on the widespread awareness and adoption of the claim. Understanding what makes health claims successful provides useful nutrition education and product‐labeling lessons for policy makers in all countries.     

Conference Presentations and the Disclosure Milieu

Conference presentations differ from other voluntary disclosures in that the audience for the disclosure is co‐located with managers in a well‐defined physical and social setting, or “disclosure milieu.” The milieu affects the degree to which conference participants can update their prior beliefs about the firm with information signals obtained through interactions with management and other informed participants. While the average abnormal stock return and volume reactions to presentations are positive, there is a great deal of cross‐sectional variation as indicated by negative median reactions. We find that conference characteristics that determine the nature of the audience and its interactions, such as sponsor, location, size, and industry‐focus, are significantly associated with the market reaction, consistent with the disclosure milieu explaining the cross‐sectional variation in the information content of the presentation. We also find that conference characteristics explain changes in subsequent analyst and institutional investor following, consistent with the disclosure milieu creating differences in access to management by potential new investors and analysts.     

HAVE INSTITUTIONAL INVESTORS DESTABILIZED EMERGING MARKETS?

In the past few years, there has been a large increase in portfolio capital flows into emerging markets, mostly fueled by mutual funds and other institutional investors. Based on a simple variance ratio test, this paper finds that emerging stock markets as a group experienced a sharp increase in autocorrelation in total returns at a time when institutional investors began to expand significantly their holdings in these markets. These results are consistent with the view that institutional investor sentiment toward emerging markets as an asset class can at times play a critical role in determining asset prices, with shifts in sentiment resulting in periods of bubble-like booms and busts and asset price overshooting.     

CALCULATING DEVELOPER CHARGES FOR URBAN INFRASTRUCTURE: A FEASIBLE METHOD FOR APPLYING MARGINAL COST PRICING

This paper considers the application of marginal cost pricing to the calculation of developer charges, also termed exactions or impact fees, in the contemporary urban environment. We derive an “ideal” measure of long-run marginal capacity cost (MCC) of urban infrastructure expansion. Given practical difficulties in estimating MCC, we develop an alternative Adjusted Amortization Method (AAM) with less onerous data requirements. Using a simulation model we compare the magnitudes of developer charges derived from the ideal MCC measure, our AAM method and three other common approaches to the measurement of MCC. Our results show that an adjusted version of the AAM formula performs very well.     

Style‐Related Comovement: Fundamentals or Labels?

I find that economically meaningless index labels cause stock returns to covary in excess of fundamentals. S&P/Barra follow a simple mechanical procedure to define their Value and Growth indices. In doing so, they reclassify some stocks from Value to Growth even after their book‐to‐market ratios have risen, and vice versa. Such stocks begin to covary more with the index they join and less with the index they leave. Backdated constituent data from Barra reveal no such label‐related shifts in comovement during the 10 years prior to the actual introduction of the indices in 1992.     

AN EXPLORATORY COST-BENEFIT STUDY OF A BRITISH STANDARD FOR UPHOLSTERED FURNITURE FABRIC

Without an evaluation of the costs and benefits arising from the production of standards for consumer goods, consumer policy makers will be operating with incomplete information in their decision-making. A standard specification for a fabric used in upholstered furniture is costed to see what resources were used in its preparation and what benefits can be estimated to have accrued to the consumer.     

The Financial Crisis from the Family's Perspective: Evidence from the 2007–2009 SCF Panel*

This paper examines changes in families' finances as captured in the 2007–2009 Survey of Consumer Finances panel. The broad contours of changes in families' assets, debts, and wealth align with changes in the corresponding aggregate measures, but the microdata from the panel highlight substantial variation in families' experiences between 2007 and 2009. Although more than 60% of families saw their wealth decline over the two‐year period, a sizable fraction experienced gains in wealth, while some families' financial situations saw little change on net. The shifts in wealth do not appear to be correlated in a simple way with families' characteristics. Instead, the patterns of mixed losses, gains, and modest shifts in wealth generally hold within groups defined by demographic characteristics or by 2007 wealth or income. On the whole, changes in wealth appear to stem from changes in asset values rather than from changes in portfolio composition or debt levels.     

The Effects of Advertising,Social Influences,and Self-Efficacy on Adolescent Tobacco Use and Alcohol Consumption

Exploring the simultaneous effects of key variables on the unhealthy consumption behavior of adolescents, two studies focused on the relative effects of advertising, parental and peer influence, and self-efficacy on adolescent tobacco use and alcohol consumption. The results suggest that (1) advertising effects are largely neutralized by parental and peer influence; (2) peer and parental influence strongly predict adolescent tobacco use and alcohol consumption; and (3) self-efficacy is a weak predictor of both adolescent risk behaviors.
