The EMH cannot apply in a world in which investors differ in their exp — Steve Keen

"Thus while diminishing returns do exist when industries are broadly defined, no industry can be considered in isolation from all the others, as supply and demand curve analysis requires."

"In general then, and contrary to Friedman, abandoning a factually false heuristic asumption will normally lead to a better theory — not a worse one."

"Which comes first — price being set by the intersection of supply and demand, or individual firms equating marginal cost to price?"

"Since in reality the stock market is inhabited by mere mortals, there is no way that the stock market can be efficient in the way that economists define the term."

"This ascendancy of economic theory has not made the world a better place. Instead, it has made an already troubled society worse: more unequal, more unstable, and less efficient."

"Why do economists persist in modelling the economy with static tools when dynamic ones exist; why do they treat as stationery an entity which is forever changing?"
