 Now assume that the operator is just like the average firm, except with respect to the operator's ability to improve efficiency.If the operator increases its productivity faster than (conversely, slower than) the average firm, then the operator's revenue will need to decrease (conversely, increase) relative to the rate of inflation.Combining these two possible differences between the operator and the average firm in the economy, the operator's revenue should change at the rate of inflation, minus (conversely, plus) the extent to which its input prices inflate less than (conversely, greater than) the rate of inflation, and minus (conversely, plus) the extent to which the operator's productivity is expected to improve at a rate that is greater than (conversely, less than) the average firm in the economy.
