The methods used by Samuelson required either explicit solutions of those equation systems or else analyses of certain approxi- mations to those systems, usually by linearization. In any event, the math- ematics was...

Evans (1924; 1925; 1930, chaps. 14–15) considered for simplicity, and avoiding further behavioral assumptions,10 the case of a quadratic cost function and a demand function that is a linear differential equation.11 In all the...
