The concept of the multiplier is extended to an economy composed of a number of sectors, such as countries, regions, industries, classes, and functional groups, or individuals, firms, and governments.

Some properties of such a system are described--in particular, the conditions for dynamic stability; the effect of changes in relative prices is also introduced.
