Cloud computing technologies have the potential to increase innovation and economic growth considerably. But many users worry that data in the cloud can be accessed by others, thereby damaging the data owner. Consequently, they do not use cloud technologies up to the efficient level. I design an...

We analyze competition among academic faculties for new researchers. The value to individual members through social interaction within the faculty depends on the average status of their fellow members. When competing for new members, existing members trade off the effect of entry on average...

By generalizing the standard solution for 2-person games into n-person cases, this paper develops a new solution concept for cooperative games: the consensus value.We characterize the consensus value as the unique function that satisfies efficiency, symmetry, the quasi dummy property and...

This paper analyzes the relations between social capital, institutions and trust.These concepts are full of ambiguity and confusion.This paper attempts to dissolve some of the confusion, by distinguishing trust and control, and analyzing institutional and relational conditions of trust.It...

In this paper we present an axiomatic analysis of several ranking methods for tournaments. We find that two of them exhibit a very good behaviour with respect to the set of properties under consideration. One of them is the maximum likelihood ranking, the most common method in statistics and...

We consider a relational economy in which economic agents participate in three types of relational economic activities: autarkic activities; binary matching activities; and plural cooperative activities. We introduce a stability notion and characterize stable interaction structures, both in the...

Abstract: We study the capacity of business associations - private, formal, noncommercial organizations designed to promote the common business interests of their members - to support contract enforcement and collective action. Inspired by recent empirical literature, our theoretical framework...

Many cooperative games, especially ones stemming from resource pooling in<br/>queuing or inventory systems, are based on situations in which each player is associated with a single attribute (a real number representing, say, a demand) and in which the cost to optimally serve any sum of attributes is...

Limit core allocations are the ones that remain in the core of a replicated economy.An equivalent notion for economies with public goods is Schweizer s concept of club e ciency under a variable number of economic agents.We extend this notion to economies with goods that have a semi-public...

In this paper we axiomatically characterize two recursive procedures for defining a social group.The first procedure starts with the set of all individuals who define themselves as members of the social group, while the starting point of the second procedure is the set of all individuals who are...
