Arbitrage Pricing Theory
Focusing on asset returns governed by a factor structure, the APT is a one-period model, in which preclusion of arbitrage over static portfolios of these assets leads to a linear relation between the expected ...

Arbitrage Pricing Theory
The arbitrage pricing theory (APT) was developed primarily by Ross (1976a; 1976b). It is a one-period model in which every investor believes that the stochastic properties of returns of capital assets are cons...

On the core and nucleolus of minimum cost spanning tree games
We develop two efficient procedures for generating cost allocation vectors in the core of a minimum cost spanning tree (m.c.s.t.) game. The first procedure requires O(n 2) elementary opera...

Error bounds for the aggregated convex programming problem
Applied mathematical programming problems are often approximations of larger, more detailed problems. One criterion to evaluate an approximating program is the magnitude of the difference between the optimal o...

Minimum cost spanning tree games
We consider the problem of cost allocation among users of a minimum cost spanning tree network. It is formulated as a cooperative game in characteristic function form, referred to as a minimum cost spanning tr...

The nucleolus and the essential coalitions
Gillies [1959] showed that the core of a game depends only on the vital coalitions. We show that the essential coalitions—which include the vital coalitions—determine the nucleolus if the core is not empty.
