16. We look at things from the point of view of one firm: a car assembly business. Right now, it gets all its inputs via the market and sells all its output via the market

17. Car assembly A car assembly business

18. This firm can be thought of as one component of a larger “car production” supply chain:

19. Let us focus only on the ‘central’ part of this supply chain. We begin with a situation in which each activity along the supply chain is undertaken by a separate firm.

20. Vertical integration But there may be good reasons why the car assembler might choose to link ‘upstream’ and/or ’downstream’ with other parts of the supply chain … And so become a vertically integrated company.

24. Now envisage three separate supply chains:

25. Horizontal integration Meanwhile, distinct firms undertaking iron ore extraction and processing activities might choose to combine (or integrate)… and so become a horizontally integrated single company. (Two separate car assembly firms might also choose to combine, but we don’t show this here).

28. Vertical and horizontal integration It may make sense for two separate materials transport and storage companies to merge too. Moreover, it may be sensible to combine the integrated materials storage and transport company with the combined extraction and processing company. If this were to occur, it would generate a single horizontally and vertically integrated company.

29. Economies of scope (Related diversification) There are potential synergies between car and motor cycle production activities. We might observe integration among such businesses where economies of scope exist, generating those synergies.
