Information may be transmitted directly from a sender to a receiver, or indirectly through intermediaries. How do intermediaries affect the reporting truthfulness of an informed sender? When does he prefer using intermediaries? In this model, an objective sender or intermediary passes on information truthfully, while a biased one wants to push a particular agenda but also has reputational conce...

Cake cutting is a common metaphor for the division of a heterogeneous divisible good. There are numerous papers that study the problem of fairly dividing a cake; a small number of them also take into account self-interested agents and consequent strategic issues, but these papers focus on fairness and consider a strikingly weak notion of truthfulness. In this paper we investigate the problem of...

Dynamic resource assignment is a common problem in multi-agent systems. We consider scenarios in which dynamic agents have preferences about assignments and the resources that can be assigned using online auctions. We study the trade-off between the following online auction properties: (i) truthfulness, (ii) expressiveness, (iii) efficiency, and (iv) average case performance. We theoretically a...

In the modern era, abundant information is easily accessible from various sources, however only a few of these sources are reliable as they mostly contain unverified contents. We develop a system to validate the truthfulness of a given statement together with underlying evidence. The proposed system provides supporting evidence when the statement is tagged as false. Our work relies on an infere...

We study the frugality ratio of truthful mechanisms in path auctions, which measures the extent to which truthful mechanisms “overpay” compared to non-truthful mechanisms. In particular we consider the fundamental case that the graph is composed of two node-disjoint s-t-paths of length s1 and s2 respectively, and prove an optimal √ s1s2 lower bound (an improvement over √ s1s2/2). This implies t...

The article presents and justifies the thesis that way of understanding knowledge has changed significantly over last century. This change consists in departing from classic definition formulated by Plato, particular questioning subjective role man as holder abandoning claims to truthfulness knowledge. process was an intensive evolution; its elements are given justified text. Its source a deep ...

Abstract We conduct a laboratory experiment to investigate how different deliberative structures of varying inclusiveness affect collective decisions in the presence economic conflict. An electorate consists two groups, one informed and uninformed about an uncertain state economy. This affects payoffs differently for groups. study three that vary are included pre-vote communication. Compared wi...
