In engineering, there's something called impedance matching:

In economics, there's something called the Laffer curve (which I would imagine many on this forum are familiar with):

I was curious to see if I could find something that made a connection or correlation between the two concepts; I didn't exactly find something that did that, but I did find this: http://criercurve.blogspot.com/2008/...fer-curve.html

Unfortunately it requires an understanding of calculus (that's reality - sorry), but if you can follow it, what do you think (especially if you have a background in math, physics, or engineering)?
