They act as though they are resolute, risk assuming operators. They make all the right moves, utter all the right sentences and emit the perfect noises. But when push comes to shove - they recoil, retreat, defeated before staging a fight. Thus, they waste the collective resources of all that the operators that they get involved with. They are known to endlessly review projects, often change their minds, act in fits and starts, have the wrong priorities (for an efficient economic functioning, that is), behave in a self defeating manner, be horrified by any hint of risk, saddled and surrounded by every conceivable consultant, glutted by information. They are the stick in the spinning wheel of the modern marketplace. 4. The former kind of operators obviously has a character problem. Yet, there is a more problematic species: those suffering from serious psychological problems, personality disorders, clinical phobias, psychoneuroses and the like. This human aspect of the economic realm has, to the best of my knowledge, been neglected before. Enormous amounts of time, efforts, money and energy are expended by the more "normal" - because of the "less normal" and the "eccentric". These operators are likely to regard the maintaining of their internal emotional balance as paramount, far over-riding economic considerations. They will sacrifice economic advantages and benefits and adversely affect their utility outcome in the name of principles, to quell psychological tensions and pressures, as part of obsessive-compulsive rituals, to maintain a false grandiose image, to go on living in a land of fantasy, to resolve a psychodynamic conflict and, generally, to cope with personal problems which have nothing to do with the idealized rational economic player of the theories. If quantified, the amounts of resources wasted in these coping manoeuvres is, probably, mind numbing. Many deals clinched are revoked, many businesses started end, many detrimental policy decisions adopted and many potentially beneficial situations avoided because of these personal upheavals. 5. Speculators and middlemen are yet another species of parasites. In a theoretically totally efficient marketplace - there would have been no niche for them. They both thrive on information failures. The first kind engages in arbitrage (differences in pricing in two markets of an identical good - the result of inefficient dissemination of information) and in gambling.
