Many online systems for bilateral transactions elicit performance feedback from both transacting partners. Such bilateral feedback giving introduces strategic considerations. We focus on reciprocity in the giving of feedback: how prevalent a strategy of giving feedback is only if feedback is first received from one’s trading partner. The overall level of feedback activity clearly depends on the...

We study a game in which the proposer can issue an extended or exploding offer. The responder is waiting for a better alternative, and an exploding offer has to be accepted or rejected before the responder knows whether a better alternative will arrive. An extended offer allows the responder to wait and first learn about the outcome of a better alternative. The responder, after accepting the pr...

INTRODUCTION The aim of the present work was to evaluate the resistance to flexural fatigue of Reciproc R25 nickel-titanium files, 25 mm, used in continuous rotation motion or reciprocation motion, in dynamic assays device. METHODS Thirty-six Reciproc R25 files were divided into 2 groups (n = 18) according to kinematics applied, continuous rotary (group CR) and reciprocation motion (group RM)...

This paper investigates consumers’ use of Electronic Word-of-Mouth System (EWOMS) after negative consumptions. We conceptualize providing product information to a EWOMS as a possible means to revenge. Our empirical study shows that this conceptualization is valid. The unsatisfied consumers who viewed the EWOMS as a revenging tool also indicated heightened likelihood of providing information to ...

The theory of reciprocal altruism offers an explanation for the evolution of altruistic behaviours among unrelated animals. Among primates, grooming is one of the most common altruistic behaviours. Primates have been suggested to exchange grooming both for itself and for rank-related benefits. While previous meta-analyses have shown that they direct their grooming up the hierarchy and exchange ...

When does a person who has been trusted reciprocate that trust? Kiyonari, Yamagishi, Cook, and Cheshire (2006) compared behavior in trust games and faith games and showed that in one-shot games, players who were trusted did not reciprocate that trust. In an experiment using trust games and dictator games, we examined what type of trust would elicit reciprocation of that trust by the trustee. In...

Consider people dividing their time and effort between friends, interest clubs, and reading seminars. These are all reciprocal interactions, and the reciprocal processes determine the utilities of the agents from these interactions. To advise on efficient effort division, we determine the existence and efficiency of the Nash equilibria of the game of allocating effort to such projects. When no ...
