Anti-Equilibrium (1971) was well ahead of its time in emphasising that (i) economics should draw from biology, rather than physics, as its methodological underpinning; (ii) evolutionary logic requires a different type of decision-making in simple, routine matters, as opposed to large and important decisions; (iii) the most important production processes are non-linear, with increasing returns to scale being the rule, rather than the exception in modern capitalist economies and — in conclusion — that there is no such thing as general equilibrium. In modern societies, goods and services are either in shortage (Socialism) or in a state of oversupply (Capitalism). It is either a buyers’ market or sellers’ market.
