Open with LBRYIn which we explain economic equilibrium, how to make money from nothing, and every fundamental force in physics.
If you'd like to read a (very) rigorous description of gauge theory in economics, check out this paper by Lee Smolin: http://arxiv.org/pdf/0902.4274v1.pdf
And if you're an economist rather than a physicist, check out "The Index Number Problem: A Differential Geometric Approach" by Pia Malaney: http://bit.ly/JKS5lh
