            Question 9       

 

  1. Which of the following correctly explains why sellers in a perfectly competitive market are price takers?                 a.  There  are many sellers, and so the market process generates an equilibrium  price that cannot be influenced by any one seller. Thus they have no  choice but to take the price generated by the market process.                  b.  Individual  buyers in a competitive market have the power to influence price, and  thus can impose prices and other conditions on powerless sellers.                  c.  There are few sellers, and so they have the power to take whatever price they want.                  d.  Sellers  in a competitive market have the power to influence price by colluding  with one another and using quotas to limit overall market output and  thus raise price.
