Producers, dealers and workers would not easily see why they should accept reduced prices and wages. Rather, they would hesitate making changes until they were sure that their costs or expenses had also been reduced. Brown was alluding to the ‘who-goes-first problem’ explained below.

One cannot consistently suppose that the price system is a communication mechanism – a device for mobilizing and coordinating knowledge dispersed in millions of separate minds – and also suppose that people already have the knowledge that the system is working to convey (compare Garrison, 2001, p. 27).
