List and explain the determinants of Demand, distinguishing between the movement along a demand curve and a shift in a demand curve. Use diagrams as appropriate
The Law of Demand states that the quantity of a good demanded will fall as its price rises and will rise as the price falls – all things being equal. Quantity demanded of a good is therefore inversely related to price. The determinants of Demand are: • Price of the good itself. • Price of
