Chapter 17: Formalization and mathematical modelling
Claims that economics is close in spirit and principle to mathematics have been reiterated many times; a well-known one is William S. Jevons’s “our science must be mathematical, simply because it deals with quantities” (1871 : 1.5, original emphasis).

The history of mathematical modelling in economics has not been a linear one. The profession privileged the verbal form for long, and even when the formal approach gradually gained ground, it often had to defend itself against hefty criticisms. Today’s widespread consensus around formalization does not prevent doubts from occasionally resurfacing.
