Actually the link between economy and neural network is quite strong historically. Friedrich Hayek is an economist who invented the word catallaxy to describe "the order brought about by the mutual adjustment of many individual economies in a market" [2]. Then he went on to work on a global theory of the brain, and was cited by Frank Rosenblatt in 1958 as an inspiration for the model of the perceptron [3].
