Development of a coherent methodology for supply chain vs. supply chain competition remains elusive in literature in terms of purpose, approaches and theoretical foundations. The purpose of this paper is to identify suitable theories of competition from which supply chain vs. supply chain competition may be further developed. Paper explores literature on competition theories, competition and it...

Traditional supply chain inventory modes with trade credit usually only assumed that the up-stream suppliers offered the down-stream retailers a fixed credit period. However, in practice the retailers will also provide a credit period to customers to promote the market competition. In this paper, we formulate an optimal supply chain inventory model under two levels of trade credit policy with d...

We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we compare the effect of adding a contract market with the introduction of an additional competitor, changing ...

Transmission constraints limit competition and arbitrageurs’ possibilities of exploiting price differences between commodities in neighbouring markets. We analyze radial transmission-constrained networks with local demand shocks, where spatially distributed oligopoly producers compete with supply functions, as in wholesale electricity markets. We prove existence and uniqueness of supply-functio...

This coordination service is frequently offered by a central operator (the so-called market operator), who actively intervenes in the market as an organiser or broker. The operator collects the bids and asks in a database and orders them according to a specific coo...
