Let’s do a basic welfare comparison between consumers and producers in a market for widgets.  Say that the relationship between the quantity of widgets supplied and the price is given by the equation qS = [b]p – 120, while quantity demanded is given by the equation qD = 240 – p. Solve for the equilibrium price, p*, and the equilibrium number of widgets sold, q*.  Then calculate consumer surplus using the formula CS =
