We conduct a two-stage game experiment with a non-excludable public good. In the first stage, two subjects choose simultaneously whether or not they commit to contributing nothing to provide a pure public good. In the second stage, knowing the other subject’s commitment decision, subjects who did not commit in the first stage choose contributions to the public good. We found no support for the ...

In this paper we describe an approach to the problem of weighting various factors that contribute to an analysis or outcome of a problem situation and discuss issues about weighting as they touch upon our case-based reasoned HY@O. In HYPO, we take the approach of delaying for as long as possible any assignment of weights-and of symbolically comparing the “weights” of competing factors. We call ...

Many violent relationships are characterized by a high degree of cyclicality: women who are the victims of domestic violence often leave and return multiple times. To explain this we develop a model of time inconsistent preferences in the context of domestic violence. This time inconsistency generates a demand for commitment. We present supporting evidence that women in violent relationships di...

We consider the related notions of two-prover and of relativistic commitment schemes. In recent work, Lunghi et al. proposed a new relativistic commitment scheme with a multi-round sustain phase that keeps the binding property alive as long as the sustain phase is running. They prove security of their scheme against classical attacks; however, the proven bound on the error parameter is very wea...

Negotiations often take time, thereby delaying the implementation of agreements which are to the mutual advantage of the bargaining partners. If the negotiators are all impatient, then these delayed agreements must be inefficient, as all participants must strictly prefer an immediate agreement on the same terms. The inefficiency of delayed agreements poses an important explanatory question: Why...

We present the first universally verifiable voting scheme that can be based on a general assumption (existence of a non-interactive commitment scheme). Our scheme is also the first receipt-free scheme to give “everlasting privacy” for votes: even a computationally unbounded party does not gain any information about individual votes (other than what can be inferred from the

Introduction. Commitment schemes are one of the most fundamental primitives in cryptography. A commitment scheme is a two-party protocol consisting of two phases, the commit and the open phase. The goal of the commitment is to allow the sender to transmit information related to a message m during the commit phase in such a way that the recipient learns nothing about the message (hiding property...

A positive relationship between employee engagement and affective commitment is already documented in the literature. However, we do not adequately know how engagement is associated with continuance and normative commitment. Using survey methodology we find that while engagement has a non-significant positive association with continuance commitment, it has a positive association with normative ...

At the core of Wilson et al.'s paper stands the question of intentional change. We propose to extend this notion by introducing concepts from the domains of innovation and knowledge creation. By going beyond their "acceptance and commitment therapy" approach we present a comprehensive framework for a theory of change culminating in the change strategy of "learning from the future as it emerges."
