Alban William Housego "A. W." "Bill" Phillips, MBE was a New Zealand economist who spent most of his academic career as a professor of economics at the London School of Economics (LSE). He invented the Phillips curve of economics in 1958. He also designed and built the MONIAC hydraulic economics computer in 1949.

The Phillips Machine, also known as the MONIAC, Phillips Hydraulic Computer and the Financephalograph, is an analogue computer which uses fluidic logic to model the workings of an economy. The name "MONIAC" is suggested by associating money and ENIAC, an early electronic digital computer.
