If it can be ascertained experimentally that the 3 × 3 Majorana neutrino mass matrix Mν has vanishing determinants for one or more of its 2 × 2 submatrices, the theoretically well-known canonical seesaw mechanism may be revealed as its progenitor. I show how these two things are connected and offer a realistic Mν with two zero subdeterminants as an example. It is a common theoretical belief in ...

Sanctioning in the face of uncertainty has been investigated from the perspective of signaling models, in which an informed target sends a signal and the sanctioner decides to sanction or not. As the more powerful power, however, the sanctioner could take the lead rather than react to the action of the target. Borrowing from contract theory, I present a new approach to the sanctioning of a targ...

Privacy Concerns, Voluntary Disclosure of Information, and Unraveling: An Experiment by Volker Benndorf, Dorothea Kübler and Hans-Theo Normann* We study the voluntary revelation of private, personal information in a labor-market experiment with a lemons structure where workers can reveal their productivity at a cost. While rational revelation improves a worker's payout, it imposes a negative ex...

some of the islamic philosophers such as farabi and mulla sadra supporting the belief in sacred and divine revelation, began to give a philosophical explanation in the field. in philosophical explanation of revelation, revealed facts can be divided into two: general and particular, perceived respectively by the prophet`s intellect and imagination. both the philosophers when explaining divine re...

A firm owns the investment rights over one undeveloped oilfield with technical uncertainties on the size and quality of the reserve. In addition, the long run expected oil price follows a stochastic process. The firm needs to select the best alternative of investment in information with different costs and different revelation powers. The modeling of technical uncertainty uses the practical con...

We consider the effects a public revelation of information (e.g. rating, grade) has on trading in a dynamic signaling model. Competing buyers offer prices to a privately informed seller who can reject them and delay trade. Delay is costly and the seller has no commitment to its duration. The external public information allows for signaling in equilibrium. More interestingly, we characterize the...

This study examined the effects of different levels of identity revelation in relation to aspects most relevant to engaged online learning activities. An online learning system supporting question-generation and peer-assessment was adopted. Three 7 grade classes (N=101) were assigned to three identity revelation modes (real-name, nickname and anonymity) and observed for six weeks. A pretest-pos...
