Their ‘becoming more expensive articles’, they ‘augment … national capital … with advantage to society’ and are ‘preferred by good economists’ (p21). The relevance of the (energy) costs of energy efficiency to rebound is disputed. 27 Rae also distinguishes between ‘efficiently’ and ‘effectually’ (in the sense of merely getting a job well done), as when the threshing machine not only saves labour but separates grain better than the flail method (p20). This again raises the question of the changing quality of the output in our numerator.

Criticizing his predecessors in all but name, Mill concludes that ‘All commodities may rise in their money price. But there cannot be a general rise of values’ (p459). Mill has a point. If, as Malthus somewhat circularly said, ‘exchangeable value is the relation of one object to some other or others in exchange’ (p51), then the concept of exchange is of no use in analysing the growth of wealth. And to the extent that prices are an abstract proxy for millions of exchange values, monetary concepts are likewise perhaps inapplicable.

For him the ‘effective desire of accumulation’ was necessary but not sufficient for the ‘increase of stock and capital’, which also required ‘augmentation’, that part of growth occurring ‘through the operation of the principle of invention’ (pp205–209 and 264 and Chapters VI and VII; see also Malthus, p339).
