Question
Chapter 7, Problem 1CACQ
To determine
The four-firm concentration ratio is to be calculated.
Expert Solution & Answer
Answer to Problem 1CACQ
Four-firm concentration ratio is 38%
Explanation of Solution
Given:
The total sales of all the 10 firms selling the product are $2000000.
The first four firm's sales are $260000, $220000, $150000 and $130000
The four-firm concentrationratio measures the proportion of sale of industry being done by top four firms. It shows market power in an industry.
Since, the first four firm's sales are $260000, $220000, $150000 and $130000, the four-firm concentration ratio is given by:
Hence, the four-firm concentration ratio in the market for product is 0.38 or 38%.

I need help figuring this out. I'm pretty sure this is correct?If Zambia is open to international trade in oranges without any restrictions, it will import 180 tons of oranges.I can't figure these two out:
1) Suppose the Zambian government wants to reduce imports to exactly 60 tons of oranges to help domestic producers. A tariff of ???? per ton will achieve this.
2) A tariff set at this level would raise ????in revenue for the Zambian government.

P₁ and P2 as the prices of those two goods and let M be per period money income. Derive each of
the following:
a) the ordinary or Marshallian demand functions q₁ = d₂ (P₁, P₂, M) for i = 1,2 [3 Marks]
b) the compensated or Hicksian demand functions q₁ = h₂ (P₁, P2, M) for i = 1,2 [3 Marks]
c) the Indirect Utility Function uº = v(P₁, P2, M) [3 Marks]
d) the Expenditure Function E(P1, P2, U°) [3 Marks]
