Industry structure is often measured by computing the Four-Firm Concentration Ratio. Suppose you have an industry with 20 firms and the CR is 30%. How would I describe this industry? Suppose the demand for the product rises and pushes up the price for the good. What long-run adjustments would I expect following this change in demand? What does my adjustment process imply about the CR for the industry?© BrainMass Inc. brainmass.com March 4, 2021, 6:06 pm ad1c9bdddf
Concentration ratios are calculated based on the market shares of the largest firms in the industry.

When the demand for the product rises and pushes up the price for the ...
