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...

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...

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...

Kudüs, kadim tarihi ve kendisine atfedilen kutsiyeti ile bugün her iki kişiden biri için kutsal mekân olarak kabul edilmektedir. Tarih boyunca bu şehir hem dini alanda de siyasi çatışmaların merkezinde bulunmuştur. Haiz olduğu önemden dolayı şehir, birçok farklı medeniyet, kültür millete ev sahipliği yapmıştır. Yahudilik Hristiyanlık İslam dinlerinde merkezi bir kutsiyet değeri taşıyan kent, üç...

The effects of preference revelation on allocational and Pareto efficiency are studied in a multi-attribute reverse English auction. Multi-attribute reverse auctions have been proposed as market institutions for electronic request for quotation buying processes. Preference revelation is a crucial question in multi-attribute reverse auctions in terms of the efficiency of auction outcomes. Result...

We reverse the standard sequence of a complete contracting model: first the agent takes an action, then she alone observes the stochastic outcome and sends a message to the principal. Presuming of the validity of the Revelation Principle, the optimal (direct) mechanism with audit requires a two-part tariff to be offered to the agent, which weakens the ex ante incentives for effort. We then esta...

the question has always been raised throughout history whether human beings need to follow the prophets or divine revelation to achieve salvation. there will be no need, as some believe, to follow divine teachings once human beings reach intellectual maturity; however, others insist on the permanent need for guidance from god due to inadequacy of human reason. in the third or fourth century ah,...
