Chapter 3

Q1.

Market efficiency is the degree of which the prices in the particular market replicates vital information of the market. In the long run, a perfectly competitive market achieves allocative and productive efficiency. It means that there is no waste in the production process since resources are allocated at a socially preferred level. Therefore, the prices in the perfectly competitive market are equal to the lowest potential average cost.

Q2.

Therefore, there is no discrimination implying that buyers and sellers must deal with each other openly at the market price. Products in the market are also homogeneous and the factor of production are perfectly mobile thus the cost of production is the same across the market. If the perfectly competitive market assumptions are not valid, the market will lose all its sales to its competitors.

Q3.
