This paper proposes axiomatic foundations of expectation formation rules, by which deviating players anticipate the reaction of external players in a partition function game. The projection rule is the only rule satisfying subset consistency and responsiveness to the original partition of...

orldwide, postal and delivery economics has attracted considerable interest. Numerous questions have arisen, including the role of regulation, funding the Universal Service Obligation, postal reform in Europe, Asia and North America, the future of national postal operators, demand and pricing...

We consider the allocation of corporate control in a company with two large and a continuum of small shareholders. Control is determined in a shareholders' meeting, where the large shareholders submit competing proposals in order to attract the vote of small shareholders. The presence of...

We analyze dynamic assignment problems where agents successively receive different objects (positions, offices, etc.). A finite set of n vertically differentiated indivisible objects are assigned to n agents who live n periods. At each period, a new agent enters society, and the oldest agent...

This paper proposes new concepts of strong and coalition-proof correlated equilibria where agents form coalitions at the interim stage and share information about their recommendations in a credible way. When players deviate at the interim stage, coalition-proof correlated equilibria may fail to...

Postal markets are open to competitor for a long time. But, with a few exceptions, the competitors of the incumbent postal operator are currently active on the upstream segments of the market -preparation,collection, outward sorting and transport of mail products. With the further steps planed...

This paper studies the core of combined games, obtained by summing two coalitional games. It is shown that the set of balanced transferable utility games can be partitioned into equivalence classes of component games whose core is equal to the core of the combined game. On the other hand, for...

This paper studies the endogenous formation of alliance in conflicts offering a survey of the recent literature and providing new results. We analyze the effect of group sizes on conflict, study endogenous alliance formation in a general model of conflict with linear technology and discuss...

This paper studies optimal pricing in networks in the presence of local consumption or price externalities. It analyzes the relation between prices and nodal centrality measures. Using an asymptotic approach, it shows that the ranking of optimal prices and strategies can be reduced to the...
