Great debate is being waged between whether strategic mortgage defaulters follow a herd for social reasons or mimic others' behavior for informational gain. Using functional magnetic resonance imaging (fMRI), the latest neurological technology allowing for observation of brain activity during strategic mortgage default decision-making, we find that when defaulters learn of peer default behavior, they acknowledge the social component of the decision, but feel freer to make their own decisions. Alternatively, when observing the behavior of a maven (real estate expert), borrowers still consider the social aspect of the decision (although to a lesser extent), but ultimately follow the maven who presumably possesses a greater information set. Alarmingly, borrowers only significantly follow the herd when mavens advocate strategic default, not when they recommend against it.

This paper tests the empirical predictions of recent theories of the endogenous entry of bidders in auctions. Data come from a field experiment, involving sealed-bid auctions for collectible trading cards over the Internet. Manipulating the reserve prices in the auctions as an experimental treatment variable generates several results. First, observed participation behavior indicates that bidders consider their bid submission to be costly, and that bidder participation is indeed an endogenous decision. Second, the participation is more consistent with a mixed-strategy entry equilibrium than with a deterministic equilibrium. Third, the data reject the prediction that the profit- maximizing reserve price is greater than or equal to the auctioneer's salvage value for the good, showing instead that a zero reserve price provides higher expected profits in this case.

Research on competitiveness at the individual level has emphasized sex as a physiological determinant, focusing on the gap in preference for competitive environments between young men and women. This study presents evidence that women's preferences over competition change with age such that the gender gap, while large for young adults, disappears in older populations due to the fact that older women are much more competitive. Our finding that tastes for competition appear just as strong among older women as they are among men suggests a simple gender-based view of competitiveness is misleading; age seems just as important as sex. These findings are consistent with one of the most commonly cited views on the deeper origins of gender differences: that they stem at least in part from human evolution.

Firms spend billions of dollars annually on new product and label designs in order to attract and retain customers. The issue of labeling is also important to government agencies and nonprofit labeling organizations. For example, the U.S. Food and Drug Administration has an organizational body in its Office of Nutritional Products that deals with issues of food and dietary supplement labeling. The U.S. Department of Agriculture's Food Safety and Inspection Service also deals with labeling through its Labeling and Consumer Protection Staff. These government agencies spend millions of dollars trying to ensure that food labels adequately inform consumers. One issue that has not been examined is the welfare difference to consumers from alternative labeling schemes/regulations. It seems likely that different labels would differ in effectiveness at informing consumers.
