Disclosure Control is the discipline concerned with the modification of data containing confidential information about individual entities, such as persons, households, businesses, etc. in order to prevent third parties working with these data from recognizing entities in the data and thereby disclosing information about these entities. In very broad terms, disclosure risk is the risk that a gi...

Background: In the treatment and health process, there are a lot of dangers to patients, and the increased number of medical errors is one of the most important circumstances of this process. Objective: The present research purposed to decrease medical errors through disclosure of them in hospitals of Tehran University of Medical Sciences. M...

In the recent past there have been numerous scandals around bad practices in the food industry. Although it can be easily rationalized why these bad practices have not been reported by the inflictors themselves, it is more difficult to understand why the noninflicting competitors did not report their rivals’ conspicuous acts. In this paper we study these competitors’ incentives to acquire and t...

Whether consumers are aware of potentially adverse product effects is key to private and social incentives to disclose information about undesirable product characteristics. In a monopoly model with a mix of aware and unaware consumers, a larger share of unaware consumers makes information disclosure less likely to occur. Since the firm is not interested in releasing information to unaware cons...

User Controlled Identity Management Systems have the goal to hinder the linkability between the different digital identities of a user. We perform a theoretical and an experimental study of the following information leakage problem: given a consistent view on the actions of a strong identity management system (e.g. Idemix ) where k users pseudonymously issue and show some credentials, do these ...

Disclosure is widely assumed to play an important role in corporate governance. Yet governance has not been the focus of previous academic analyses of disclosure. We consider disclosure in the context of corporate governance. We argue that disclosure is a two-edged sword. On one side, disclosure of information permits principals to make better decisions. On the other, it can create or exacerbat...

This paper explores information disclosure in matching markets, e.g., the informativeness of transcripts given out by universities. We show that the same amount of information is disclosed in all equilibria. We then demonstrate that if universities disclose the equilibrium amount of information, students and employers will not find it profitable to contract early; if they disclose more, unravel...

This paper provides a novel approach to ordering signals based on the property that more informative signals lead to greater variability of conditional expectations. A new class of precision criteria is defined by combining this approach with different variability orders and its relation with existing criteria of informativeness explored. Then, precision criteria are used to study the incentive...
