In this paper I try to argue for the desirability of analog computation in economics from a variety of perspectives, using the example of the Phillips Machine. Ultimately, a case is made for the underpinning of both analog and digital computing theory in constructive mathematics. Some conceptual...

In this paper it is claimed that the Phillips machine, contrary to what is sometimes believed, is a nonlinear mechanism. Phillips (1950) presented his machines, as formally described, with linear differential equations. In doing so, he fell into what Samuelson came later to define as the...

\tThe assumption that production in an economic system may be described by an aggregate neoclassical production function is at the foundation of most modern equilibrium neoclassical business cycles and growth models. Its validity requires stringent assumptions on individual production functions...
