Explanation / Answer

1) Inferior goods are those whose demand increases as price increase or demand decrease while price decreases. Eg : course grains. Normal goods are those goods whose demand increases as price falls and demand falls as price increases. Two goods are substitutes if demand for good 1 increases if price of good 2 falls and vice-versa. Here since increase in price of adidas shoes increase demand for nike shoes, adidas shoes and nike shoes are substitutes.

2) Positive statements are fact-based while normative statements are subjective and value-based. Thus, statement C is a positive statement.

3) Whenever profit maximizing price is below the average cost, the firm should shut down. This is because at this point the firm would be dealing in losses.
