Circulation represents the lifeblood of all flow-systems, be they economies, ecosystems, or living organisms.
By Sally Goerner – Circulation represents the lifeblood of all flow-systems, be they economies, ecosystems, or living organisms. In living organisms, poor circulation of blood causes necrosis that can kill. In the biosphere, poor circulation of carbon, oxygen, nitrogen, etc. strangles life and would cause every living system, from bacteria to the biosphere, to collapse. Similarly, poor circulation of money, goods, resources, and services leads to economic necrosis – the dying off of large swaths of economic tissue that ultimately undermines the health of the economy as a whole.
In flow systems, balance is not simply a nice way to be, but a set of complementary factors – such as big and little; efficiency and resilience; flexibility and constraint – whose optimal balance is critical to maintaining circulation across scales. For example, the familiar branching structure seen in lungs, trees, circulatory systems, river deltas, and banking systems connects a geometrically constant ratio of a few large, a few more medium-sized, and a great many small entities. This arrangement, which mathematicians call a fractal, is extremely common because it’s particular balance of small, medium, and large helps optimize circulation across different levels of the whole. Just as too many large animals and too few small ones creates an unstable ecosystem, so financial systems with too many big banks and too few small ones tend towards poor circulation, poor health, and high instability.
In his documentary film, Inequality for All , Robert Reich uses virtuous cycles to clarify how robust circulation of money serves systemic health. In virtuous cycles, each step of money movement makes things better. For example, when wages go up, workers have more money to buy things, which should increase demand, expand the economy, stimulate hiring, and boost tax revenues. In theory, government will then spend more money on education which will increase worker skills, productivity and hopefully wages. This stimulates even more circulation, which starts the virtuous cycle over again. In flow terms, all of this represents robust constructive flow, the kind that develops human and network capital and enhances well-being for all.
Of course, economies also sometimes exhibit vicious cycles, in which weaker circulation makes everything go downhill – i.e., falling wages, consumption, demand, hiring, tax revenues, government spending, etc. These are destructive flows, ones that erode system health. more>
