Delegation versus Authority by Daniel Krähmer The paper studies the role of delegation and authority within a principal-agent relation in which a non-contractible action has to be taken. The agent has private information relevant for the principal, but has policy preferences different from the principal. Consequently, an information revelation problem arises. We contribute to the literature by ...

Task delegation is a mechanism that supports organisational flexibility in the humancentric workflow systems, and ensures delegation of authority in access control systems. In this paper, we define an approach to support dynamic delegation of authority within an access control framework. The novelty consists of reasoning on authorisation dependently on task delegation events, and specifies them...

In a typical corporate hierarchy, the manager is delegated the authority to make strategic decisions, and to contract with other employees. We study when such delegation can be optimal. In centralization, the owner retains the authority, which fails to motivate the manager to acquire valuable information, leading to suboptimal decisions and inefficient incentive provision to the worker. Benefic...

Authority and power permeate political, social, and economic life, but empirical knowledge about the motivational origins and consequences of authority is limited. We study the motivation and incentive effects of authority experimentally in an authoritydelegation game. Individuals often retain authority even when its delegation is in their material interest—suggesting that authority has nonpecu...

The Canadian Department of National Defence (DND) is shifting its methods for the delegation and exercise of authority from paper-based to electronic-based means. DND has deployed a commercial PKI but there is no general technical solution presently employed by DND for access control or electronic authorization of workflow in distributed processing environments. The aim of this research is to s...

We present HM-ABE, a hierarchical multi-authority attributebased encryption scheme with policy delegation, that generalizes current work significantly. Current methods require encryptors to build ciphertext access policies themselves, using attributes published by authority domains. This causes problems, both since authorities may not publish sensitive attributes, and since users may not unders...
