EC 1 Lecture 9 Dr. Bresnock 2 Price and Output Determination : Pure Competition Characteristics : 1. Large # of Independent Sellers 2. Standardized, or Homogeneous, Product – little ability for sellers to differentiate product; buyers indifferent between sellers 3. “Price Takers” not “Price Makers – sellers are “quantity adjusters”. **(see below) 4. No Barriers to Entry or Exit – no significant financial, technological, or legal obstacles 5. Only “Product” Advertising – i.e. California raisins, California cheese, “pork the other white meat”, “where’s the beef” Graph 1 Price Determination for Purely Competitive Firm INDUSTRY F I R M Some Terms : TR = Total Revenue = Price X Quantity AR = Average Revenue = Per Unit Revenue = TR Q MR = Marginal Revenue = Additional Revenue per an Additional Unit of Output = TR = TR 2 – TR 1 Q Q 2 – Q 1
