who created the Hansen Rule Curve use by the New York Thruway Authority? In other words who signed the agreement?

The Hicks-Hansen IS-LM Model:I think NYTA signed up for it as part of an accounting program with Hanson and his partners.The Hubbert curve was put out by,Hubbert, M. King. If I rember right Hanson had a partner or more.The result is that time goes into a Curve, and the curve has the elements to use as time advances.The points of the curve indicate unequal margins.
