Economic growth may involve change, but there can be change without economic growth insofar as outputs of some products or employment in some regions or industries grows while there are equal decreases elsewhere. National accounts data do not reveal such shifts, yet they may involve investment and disinvestment, require the acquisition of new skills and cause changes in the location of economic activities. Some simple examples are provided, demonstrating that the rate of growth and the pace of change are by no means perfectly correlated. Hence separate measures of change are required if we are to understand what is happening in the economy.

There is a high degree of symmetry between economic goods and economic bads. Snow, litter and street mud are cited as examples. Economic growth obviously results in an increase in the supply of bads as well as goods. In addition, however, because it raises the value of time it can turn goods into bads and it can result in an end to the transformation of bads into goods. This is illustrated in some detail by two case studies for nineteenth century London, relating to domestic refuse and to horse manure. As a result of economic growth, horse manure had almost ceased to be an economic good and had become an economic bad by the end of the century.
