CONSIDERATIONS ON THE DEVELOPMENT OF POLITICAL METHODS FOR ABSORBING UNCERTAINTY

ALECU, Ciprian Ionel - In: EuroEconomica (2011) 5(30), pp. 39-47

There is no "standard" method used as a panaceum to reduce decision-making uncertainty. The technocratic approach on management is only valid on a free-competition market, with equal chances for everyone. In practice, this is a utopia. Knowledge-based economy changes the exogenous environment of...
