چکیده

A new light is shed on “substitutes and complements” in the maximum weight circulation problem with reference to the concepts of L-convexity and M-convexity in the theory of discrete convex analysis. This provides us with a deeper understanding of the relationship between convexity and submodularity in combinatorial optimization.

Convexity and Complementarity in Network Formation: Implications for the Structure of Pairwise Stable Networks

This paper studies the properties of convexity (concavity) and strategic complements (substitutes) in network formation and the implications for the structure of pairwise stable networks. First, different definitions of convexity (concavity) in own links from the literature are put into the context of diminishing marginal utility of own links. Second, it is shown that there always exists a pair...

Price and quantity competition in a differentiated duopoly

• Two classical models in the theory of oligopoly are those of Coumot (1838) and Bertrand (1883). In both models the equilibrium concept is the noncooperative equilibrium of Nash (1950). In the former firms set quantities. In the latter prices are the strategy variables. In a duopoly situation where firms produce a homogeneous good and marginal costs are constant and equal for both firms, the B...

Contractual and relational governance as substitutes and complements - explaining the development of different relationships

For a long time research on the management of IS outsourcing projects viewed relational and contractual governance as substitutes. However, subsequent studies provided empirical evidence for the complementary view. Recently, some authors supported the notion that relational and contractual governance mechanisms can simultaneously be complements and substitutes. Given these inconsistencies the q...
