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.

Economists are increasingly turning to the experimental method as a means to estimate causal effects. By using randomization to identify key treatment effects, theories previously viewed as untestable are now scrutinized, efficacy of public policies are now more easily verified, and stakeholders can swiftly add empirical evidence to aid their decision-making. This study provides an overview of experimental methods in economics, with a special focus on developing an economic theory of generalizability. Given that field experiments are in their infancy, our secondary focus pertains to a discussion of the various parameters that they identify, and how they add to scientific knowledge. We conclude that until we conduct more field experiments that build a bridge between the lab and the naturally-occurring settings of interest we cannot begin to make strong conclusions empirically on the crucial question of generalizability from the lab to the field.

Alzheimer patients in the early stage of the disease were asked to participate in the Dictator game, a game in which each subject has to decide how to allocate a certain amount of money between himself and another person. The game allows the experimenter to view the influence of social norms and preferences on the decision-making process. When the data from the experiment are compared with the results of an identical experiment involving two control groups with similar ages and social background, one group with Mild Cognitive Impairment patients, the other with healthy subjects, it appears that the results from the three groups are statistically undistinguishable. This is an indication that Stage I AD patients are as capable of making decisions involving social norms and preferences as any person of their age, and that whatever brain structures are affected by the disease, they do not include, at this stage, the neural basis of cooperation-enhancing social interactions.

Auction theory represents one of the richest areas of research in economics over the past three decades. Yet, whether, and to what extent, the introduction of secondary resale markets influences bidding behavior in sealed bid first-price auctions remains under researched. This study begins by examining field data from a unique data set that includes nearly 3,000 auctions (over 10,000 individual bids) for cutting rights of standing timber in British Columbia from 1996-2000. In comparing bidding patterns across agents who are likely to have resale opportunities with those who likely do not, we find evidence that is consistent with theory. Critical evaluation of the reduced-form bidding model, however, reveals that sharp tests of the theoretical predictions are not possible because several other differences may exist across these bidder types. We therefore use a laboratory experiment to examine if the resale opportunity by itself can have the predicted theoretical effect. We find that while it does have the predicted effect, a theoretical model based on risk-averse bidders explains the overall data patterns more accurately than a model based on risk-neutral bidders. Beyond testing theory, the paper highlights the inferential power of combining naturally occurring data with laboratory data.

In this study, we use functional magnetic resonance imaging (fMRI) to understand how homeowners process non-financial information when considering strategic mortgage default. We find that borrowers initially attempt to inhibit their knee-jerk reaction to retaliate against a lender who has engaged in egregious lending practices when compared to a financially conservative lender. Moreover, when defaults are rare, borrowers are less likely to default because violating the social norm results in feelings of disgust. Finally, when a lender refuses a loan modification, the borrower is found to seek retribution. Interestingly, granting even a modest loan modification removes the desire of homeowners to seek retribution towards their lender no matter what their impression of the lender may be. The results carry a number of policy implications.

This study examines strategic mortgage default on a neurological level. Specifically, we test two mainstream behavioral finance/economic theories: sunk cost fallacy and cognitive dissonance. Using fMRI technology, we identify a number of substrates within the brain that provide a neurobiological explanation for why some homeowners exercise their mortgage put option while others do not. We find that borrowers rationally do not suffer from the sunk cost fallacy as it relates to strategic default in that stye significantly prioritize their negative equity position over the amount of their initial down payment. We do, however, find neurological support that cognitive dissonance is relevant in homeowners' thought processes as they toil with the hesitancy brought on by the belief that strategic default is immortal against strong financial incentive to walk away from a substantially underwater mortgage.
