Relational Team Incentives and Ownership
This paper develops a stylized theory of internal organization of the firm based on the interplay between explicit (court-enforced) and implicit (self-enforced) incentives. The firm is modeled as a team that meets repeatedly, and is confronted with a problem of moral hazard. Two instruments are used to induce effort: court-enforced ownership shares over the stream of profits, and self-enforced ...
متن کاملEntities and Relations for Historical Relational Databases
Research to extend models of data to handle the temporal dimension has been conducted mainly in the context of the rela-tional data model. In the relational model, the primary object of database design, manipulation and retrieval is the relation, viewed extensionally as a nite set of tu-ples. A formal system for temporal re-lational data deenition and manipulation associates a temporal domain, ...
متن کاملRelational Authority and Legitimacy in International Relations
This essay develops a theory of relational authority in the most unpromising setting of international relations. Relational authority locates legitimacy in a social contract between a ruler, who provides a social order of value to the ruled, and the ruled who comply with the ruler's commands necessary to the production of that order. International politics are near universally assumed to be an ...
متن کاملCartesian Products of Relations and Relational Structures1
In this article we present several logical schemes. The scheme FraenkelA2 deals with a non empty set A , a binary functor F yielding a set, and two binary predicates P , Q , and states that: {F (s, t);s ranges over elements of A , t ranges over elements of A : P [s, t]} is a subset of A provided the following condition is satisfied: • For every element s of A and for every element t of A holds ...
متن کاملCardinality of relations and relational approximation algorithms
First, we discuss three specific classes of relations, which allow to model the essential constituents of graphs, such as vertices and (directed or undirected) edges. Based on Kawahara’s characterisation of the cardinality of relations we then derive fundamental properties on their cardinalities. As main applications of these results, we formally verify four relational programs, which implement...
