When delegation in real world scenarios is considered, the delegator (the entity that posses the privileges) usually passes the privileges on to the delegatee (the entity that receives the privileges) in such a way that the former looses these privileges while the delegation is effective. If we think of a physical key that opens a door, the privilege being delegated by the owner of the key is o...

A number of OECD countries aim to encourage work integration of disabled persons using quota policies. For instance, Austrian firms must provide at least one job to a disabled worker per 25 nondisabled workers and are subject to a tax if they do not. This “threshold design” provides causal estimates of the noncompliance tax on disabled employment if firms do not manipulate nondisabled employmen...

Don Hoi Lord, a coastal wetland in the upper gulf of Thailand, is famous for the razor clam (Solen regularis), which is a source of food and income for local fishermen. However, the razor clam population is significantly decreasing so the aim of this study was to analyze the razor clam fishery and develop a management plan engaging the different stakeholders in collective discussions. A partici...

When aggregating information from a group of agents, accepting the pieces of information shared by all agents is a natural requirement. In this paper, we investigate such a unanimity condition in the setting of propositional merging. We discuss two interpretations of the unanimity condition. We show that the first interpretation is captured by existing postulates for merging. But the second int...

Spam, by overwhelming inboxes, has made email a less reliable medium than it was just a few years ago. Spam filters are undeniably useful but unfortunately can flag non-spam as spam. To restore email’s reliability, a recent spam control approach grants quotas of stamps to senders and has the receiver communicate with a wellknown quota enforcer to verify that the stamp on the email is fresh and ...

A vexing problem in managing sales forces occurs when the sales manager does not know the characteristics of a sales territory. In this paper we show how sales quota-bonus plans can be optimally used to learn about unknown territory characteristics over a multiperiod horizon. We demonstrate this process in two scenarios—one in which the sales manager and the rep are symmetrically informed about...

1.1.1 Two Conflicting Trends Two recent and conflicting trends in Internet applications motivate the discussion in this work: video traffic becoming dominant, and usage-based pricing becoming prevalent. Video traffic becoming dominant: Video consumption is on the rise. For example, Cisco predicts that 70% of all mobile traffic will be from video alone by 2016 [1]. Likewise, wireline traffic is ...
