The duration of ownership has been shown to increase the valuation of items that people currently own as well as items they have owned in the past, a phenomenon termed the ``length-of-ownership effect.'' We hypothesize that the duration of exposure to an item will foster increased pre-ownership...

The assumption that people possess a repertoire of strategies to solve the inference problems they face has been made repeatedly. The experimental findings of two previous studies on strategy selection are reexamined from a learning perspective, which argues that people learn to select...

Recent research reported evidence that contradicts cumulative prospect theory and the priority heuristic. The same body of research also violates two editing principles of original prospect theory: cancellation (the principle that people delete any attribute that is the same in both alternatives...

Theoretical equivalence exists among various auction mechanisms, specifically the Second-Price-Auction (SPA), a competitive environment, and the BDM mechanism, a non-competitive environment. Yet, empirical studies suggest that behavior in these mechanisms may diverge. Our experimental study...

We compare and critique two measures of risk perception. We suggest that a single question --- ``How risky is the situation?'' --- captures the concept of risk perception more accurately than the multiple-item measure used by Sitkin and Weingart (1995). In fact, this latter measure inadvertently...

Three studies presented scenarios to lay people to investigate their willingness to restrict imports. Greater restriction was preferred when similar goods were made at home, when the owners of the foreign businesses made very good profits, and, less consistently, when the goods came from a low...

Although many models for risky choices between gambles assume that information is somehow integrated, the recently proposed priority heuristic (PH) claims that choices are based on one piece of information only. That is, although the current reason for a choice according to the PH can vary, all...

Researchers know very little about \textit{how} people choose mates. To remedy this, the present study examined the influence of number of potential mates and mate-standard strength on single women's choice satisfaction and strategy use. Single women chose one potential partner from a set of 4,...

In this paper I explore how the evolution of emotional expression and co-operative planning in humans may inform the way they communicate about risks, and what implication this may have for models of rationality in risk communication. In particular, I focus on aspects of human language that...

Subjects performed a decision task (Grether, 1980) in both a well-rested and experimentally sleep-deprived state. We found two main results: 1) final choice accuracy was unaffected by sleep deprivation, and yet 2) the estimated decision model differed significantly following sleep-deprivation....
