## DragIT - Revenue curves (2)

A change in the firm's output represents a movement along the demand curve (AR) and a movement along the TR curve. A shift in the demand curve would cause the total revenue curve to shift too.

The diagram below shows the current demand curve and marginal revenue curve (AR1and MR1 respectively) for product Z. Demand for this product falls by two units at all prices.
