At a given price, when demand for commodity is more than supply of the commodity then it is called excess demand. Here given price is

• less than equilibrium price

• more than equilibrium price

• less than or equal to equilibrium price

• More than or equal to equilibrium price

The demand of a commodity when measured through the expenditure approach is inelastic. A fall in its price will result in :
(choose the correct alternative)
(a) no change in expenditure on it.
(b) increase in expenditure on it.
(c) decrease in expenditure on it.
(d) any one of the above

As we move along a downward sloping straight line demand curve from left to right, price elasticity of demand : (choose the correct alternative)
(a) remains unchanged
(b) goes on falling
(c) goes on rising
(d) falls initially then rises
