We experimentally investigate delegation and communication as two alternative means of coordinations among individuals with misaligned interests. We implement in the laboratory two delegation-communication games in which a principal chooses whether to delegate her decision-making authority to an informed agent or to make the decision herself after a cheap-talk communication with the agent. In t...

We introduce Delegation Logic (DL), a logic-based knowledge representation (i.e., language) that deals with authorization in large-scale, open, distributed systems. Of central importance in any system for deciding whether requests should be authorized in such a system are delegation of authority, negation of authority, and conflicts between authorities. DL’s approach to these issues and to the ...

Multi-agent systems have a reputation for bringing with them the property of robustness. However, multi-agent systems need to be specifically designed to display this property and until now it is unclear how this can be achieved. One way of approaching this, is to try to simulate social systems, as social order is in close analogy to robustness. We discuss this analogy, give an attempt to a def...

Collaborative robotic systems, such as unmanned aircraft systems, are becoming technologically mature enough to be integrated into civil society. To gain practical use and acceptance, a verifiable, principled and well-defined foundation for interactions between human operators and autonomous systems is needed. In this paper, we propose and specify such a formally grounded collaboration framewor...

Delegation of Authority as an Optimal (In)complete Contract The present paper aims to contribute to the literature on the foundations of incomplete contracts by providing conditions under which simple delegation of authority is the solution to the complete-contracting problem of the parties. We consider a hold-up framework where both parties profit from an investment that raises the value of an...

The paper presents revocation schemes in role-based access control models. We are particularly interested in two key issues: how to perform the revocation and how to manage the revocation policy. We show how to deal with these two aspects in our delegation model based on the OrBAC formalism and its administration licence concept. This model provides means to manage several types of of delegatio...

Few studies have identi®ed determinants of delegation and consultation. To investigate this question further, we surveyed managers and subordinates in two samples and interviewed managers individually or in focus groups. The use of delegation and consultation with individual subordinates was determined in part by characteristics of the subordinates and the manager±subordinate relationship. More...

Collaborative robotic systems have much to gain by leveraging results from the area of multi-agent systems and in particular agent-oriented software engineering. Agent-oriented software engineering has much to gain by using collaborative robotic systems as a testbed. In this article, we propose and specify a formally grounded generic collaborative system shell for robotic systems and human oper...

Large amount of digital content would be stored safely in peer-to-peer network, with encrypted format. Being requested, a cipher text is downloaded from certain peer and decrypted by a delegated decryptor to obtain the clear text. Observing the need for this new kind of delegation decryption service, we propose a novel time constraint delegation scheme for decrypting p2p data in this paper. The...

We consider the problem of delegating computation, where the delegator doesn’t even know the input to the function being delegated, and runs in time significantly smaller than the input length. For example, consider the setting of memory delegation, where a delegator wishes to delegate her entire memory to the cloud. The delegator may want the cloud to compute functions on this memory, and prov...
