We define secure implementation with partially honest agents in a social choice model and we show that strategy-proofness is a necessary and sufficient condition for it. This result offers a behavioral foundation for rectangularity ; and it remains valid even with only one partially honest agent. We apply the concept to a single-crossing voting environment, and we prove that it characterizes th...

Does information processing affect individual risk-taking behaviour? This paper provides evidence that professional athletes suffer from a left-digit bias when dealing with signals about differences in performance. Using data from the highly competitive field of World Cup alpine skiing for the period of 1992–2014, we show that athletes misinterpret actual differences in race times by focusing o...

Definitive judgment about the quality of decision making is made difficult by twin problems of measurement and identification. A measure of decision-making quality is hard to formalize, to quantify, and to make practical for use in a variety of choice environments; and it is difficult to distinguish differences in decision-making quality from unobserved differences in preferences, information, ...

Inequity aversion models have dominated the behavioral economics landscape in the last decade. This study uses variants of dictator and trust games to provide empirical content to these models. We manipulate market features—such as competition over resources—to demonstrate that extant models cannot explain realistic manipulations of either game. For example, we show that if socially acceptable ...

Recent research has cast some doubt on the general validity of outcome-based models of social preferences. We develop a model based on cognitive dissonance that focuses on the importance of self-image. An experiment (a dictator game variant) tests the model. First, we find that subjects whose choices involve two psychologically inconsistent cognitions indeed report higher levels of experienced ...

Interpreting Time Horizon Effects in Inter-Temporal Choice We compare different designs that have been used to test for an impact of time horizon on discounting, using real incentives and two representative data sets. With the most commonly used type of design we replicate the typical finding of declining (hyperbolic) discounting, but with other designs find constant or increasing discounting. ...

Having successfully explored the existing relations between the S-matrix and collision times in scattering reactions to study the conventional baryon and meson resonances, the method is now extended to the exotic sector. To be specific, the collision time in various partial waves of KN elastic scattering is evaluated using phase shifts extracted from the KN → KN data as well as from model depen...

We investigate the role of respect and monetary gifts in the service industry. We report findings from purchases of more than 800 doner durum, a common lunch snack. Prior to the food’s preparation, we either give a compliment about the product, or a monetary gift by tipping. We repeat the interaction on five consecutive days. Our findings show that salespersons exhibit positive reciprocity in r...

We analyze the welfare e¤ect of governmental regulation for individuals who consider anticipated regret in their decision making process. While governmental policies by directing choice distort individual decisions in the private market they can alleviate individuals’pain associated with the feeling of regret. We specify a general model to highlight this trade-o¤ and investigate two policies mo...

We present a model of reference dependence, which assumes that reference points affect choice by directing the decision maker’s attention towards the particular goods in the reference bundle. This model makes no assumptions about the curvature of utility, and does not assume a built-in asymmetry in gains and losses. Nonetheless it is able to generate loss aversion and can explain a large number...
