We often use delegation as a commitment device if a government faces problems of timeinconsistency. McCallum (1995, AER P&P) challenged this practice, claiming that delegation merely relocates the commitment problem but does not solve it. In a model where delegation and specific policies are subject to the same commitment technology it is shown that McCallum’s conjecture holds if optimal ex-ant...

Delegation of signing capability is a common practice in various applications. Mambo et al. proposed a proxy signatures as a solution for delegation of signing capability. Proxy signatures allow a designated proxy signer to sign on behalf of an original signer. After the concept of proxy signature scheme was proposed, many variants are proposed to support more general delegation setting. To cap...

Delegation is an important concept to increase flexibility in authorization and obligation management. Due to the complexity of potential delegation relations, there is a strong need to systematically check the consistency of all delegation assignments. In this paper, we discuss the detection of delegation conflicts based on the formal definitions of a model that supports the delegation of role...

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...

Elected governments and states have delegated extensive powers to non-majoritarian institutions (NMIs) such as independent central banks regulatory agencies, courts, international trade investment organizations, which become actors in governance. But, far from having resolved the balance between political control governing competence or removed certain issues debate, NMIs faced challenges their...

We investigate trust propagation in delegation situations, which often occur in hierarchical organisations and coalition structures. In doing so we define a delegation chain representing the sub-delegation process. Such delegation chains present a problem for current trust evaluation mechanisms, which are unable to accurately divide trust among the chain members, resulting in degraded system pe...

In Role-based Access control (RBAC) permissions are associated with roles and users are made members of roles thereby acquiring the associated permissions. User delegation in RBAC is the ability of one user (called the delegating user) who is a member of the delegated role to authorize another user (called the delegate user) to become a member of the delegated role. This paper proposes a simple...

An anonymous delegation system enables individuals to retrieve rights and to delegate different subparts of these rights to different entities. The delegation procedure is anonymous, such that no collusion of entities can track an individual’s delegation behavior. On the other hand, it is ensured that a user cannot abuse her delegation capabilities. This paper introduces a general delegation mo...

This paper studies the optimal design of delegation rule in a three-tier principalintermediary-agent hierarchy. In this hierarchy, monetary transfer is not feasible, delegation is made sequentially, and all players are strategic. We characterize the optimal delegation mechanism. It is shown that the singleinterval delegation a la Holmstrom is optimal only when the intermediary is moderately bia...

Abstract Recently, in their 2019 paper, Poyago-Theotoky and Yong consider a managerial Cournot duopoly with pollution externalities emission taxes propose an explicit environmental incentive compensation contract. The authors compare several exogenous equilibria emerging the symmetric sub-games which owner offers either delegation contract or standard sales contract: abatement social welfare (r...
