This book presents a new theory of market and capitalism, detailing its key moments and general logic. It is based on the distinction between two market types: the simple commodity market and the capitalist one.In contrast to what is usually uncritically accepted, disequilibrium and "imperfect competition" are admitted here to be a functional norm of the capitalist market. The book also shows that equilibrium and "perfect competition" are admitted to be a functional anomaly, with crises considered as the result of such an anomaly. It details the general principles and concrete measures of crisis-proof policies and behavior.
