ABSTRACT
Firms in different environments essentially face different interfaces between markets. Oligopoly is the most stable type of market structure simply in virtue that there is an overlap between all three markets the firm faces, which are centralised in the ecology. Oligopoly is also efficient since it is stabilising for firms, but stability comes at a high cost, and too high a cost, for the rest of the system. This includes exclusion, exclusivity, predation, domination, subjugation, polarisation and inequality.
