I would disagree - the economy is anti-inductive[1] (in that it resists attempts to understand it). As soon as you implement the results of your sufficiently-sophisticated model, the economy will start to be influenced by that.
Any viable model of the economy would therefore have to recursively contain a model of the model of the economy and so on.
