This example illustrates the origin of the term “linear”: the graph of y = x is a straight line, while the graph of y = x 2 is a curve.

Nonlinear systems come in all shapes and sizes. Linear dynamics is a useful abstraction, but if you look long enough at any real system you consider linear, you will discover nonlinearities. It ...

Empirical demand systems that do not impose unreasonable restrictions on preferences are typically non-linear. We show, however, that all popular systems possess the property of conditional linearity.
