Using supply and demand curves show how an increase in the price of shoes affects the price of a pair of socks and the number of pairs of socks bought and sold.
Shoes and socks both are complementary to each other and are used together. Therefore, the increase in shoe price will discourage the demand for socks. Therefore, due to the decrease in demand for socks, the demand curve for socks will shift leftwards parallelly from D1D1toD2D2. The supply remaining unchanged, at the equilibrium price pe, there exists excees supply of socks, which reduces the price of socks and the new equilibrium will be at E2, with equilibrium price P2 and equilibrium quantity q2.
How will a change in the price of coffee affect the equilibrium price of tea? Explain the effect on equilibrium quantity also through a diagram.
When do we say that there is an excess demand for a commodity in the market?
Suppose the price at which the equilibrium is attained in exercise 5 is above the minimum average cost of the firms constituting the market. Now if we allow for free entry and exit of firms, how will the market price adjust to it?
Suppose the market determined rent for apartments is too high for common people to afford. If the government comes forward to help those seeking apartments on rent by imposing control on rent, what impact will it have on the market for apartments?
Explain through a diagram the effect of a rightward shift of both the demand and supply curves on equilibrium price and quantity.
When do we say that there is an excess supply for a commodity in the market?

What is budget line?
Why is the short-run marginal cost curve 'U'-shaped?
What do you mean by an ‘inferior good’? Give some examples
What do the short-run marginal cost, average variable cost and short-run average cost curves look like?
Can there be some fixed cost in the long run? If not, why?
A consumer wants to consume two goods. The prices of the two goods are Rs 4
and Rs 5 respectively. The consumer’s income is Rs 20.
(i) Write down the equation of the budget line.
(ii) How much of good 1 can the consumer consume if she spends her entire
income on that good?
(iii) How much of good 2 can she consume if she spends her entire income on
that good?
(iv) What is the slope of the budget line?
Questions 5, 6 and 7 are related to question 4.
