Microeconomics

Question 1

a)

According to the graph, if the country is producing 300 kg of food per month, it will not be able to produce any sunscreen. In order to produce 50 litres of sunscreen, it will have to give up 100 kg of food production.

b) If the country produces 150kg of food, it will have to produce 75 kg litres sunscreen in order to achieve efficiency.

c) If the country wants to produce one additional kg of food, it will have to give up 0.5 litres of sunscreen.

d) If the country wants to produce one additional litre of sunscreen, it will have to give up 2kg of sunscreen.

e) The relationship between c and d is that for every 1kg of additional food being produced, the country will have to give up 0.5 litres of sunscreen.

f) The opportunity cost for food remains constant for all levels of production. This is proved from the straight line that had been drawn in relationship between the two variables.

Question 2

a)

As the price of orange juice decreases, the quantity demamded increases.

If the wage rate is increased, the quantity of work done by the workers remains constant because of the limitations of humans.

Employees are paid low wages.

Customer service is not up to proper standards.

c) Characteristics of monopolistic competition:

Relatively large number of sellers.

Differentiated products.

Low prices.

Small market share of each competitor.

Question 3

dQ/Q ÷ dP/P

(3-2)/2 ÷ (1.2 - 1.4)/1.4

0.5 ÷ -0.1428

-3.5

Percentage change in demand / Percentage change in price

(0.9 + 0.85)/ (2+3) x (3-2)/ (0.85-0.9)

1.75 + 5 x -0.05

1.75%

Since a decrease in prices lead to an increase in quantity demanded, the products are complementary products.

dQ/Q ÷ dP/P

(2-3)/3 ÷ (1.2 - 1.2)/1.2

-0.33 ÷ 0

0

The good is a complementary product because its demand is changing without a change n price. This means that the demand is dependant on some other variable.

Profit maximization points are Price= 6 and 5, and quantity = 150 and 200

Question 5

Equilibrium rent = \$450 / month

Equilibrium quantity = 20 thousand units

At a rent of \$600 the quantity of houses rented = 10 thousand units

At a rent of \$300 the quantity of houses rented = 30 thousand units

Shortage of houses = 20 thousand units

Maximum price someone is willing to pay = \$600/ month
