To facilitate the analysis, I assume that: the cross-elasticity of demand of good ( i ) with regard to the price of good ( j ), with ( i ne j ), is negligible; the influence of the purchase of the good produced by the representative family is also insignificant; and finally, the Lagrange multiplier is constant with respect to the price of each product.
The SAM with detailed economic circulation provides the relationship between supply and demand of goods and services and keeps the principle of equivalent of three aspects.
Finally, general equilibrium is defined by the equality (in each period) between supply and demand of goods and factors, and the savings-investment identity.

In terms of partial-differential calculus, point-price elasticity of demand can be defined as follows: let \displaystyle x p,w) be the demand of goods x_1,\dotsdots,x_L as a function of parameters price and wealth, and let \displaystyle x_l(p,w) be the demand for good \displaystyle l.
