Answer:
time limitations in limited marginal utility; limited income and wealth
Explanation:
Demand curves intersect the quantity axis due to time limitations in limited marginal utility, which explains the second law of demand – the lower the price, the higher the quantity demanded. While it intersects the price axis due to limited income and wealth, which also explains the second law of demand – the higher the price, the lower the quantity demanded.
The marginal utility of a consumer is limited, because, the more of the goods consumed, the amount of satisfaction derived decreases. Hence, the demand curve intersects the quantity axis, indicating the point when the consumer derives no more satisfaction from the consumption of that good.
On the other hand, as a result of limited income of the consumer, it would come to a point when the consumer will not be able to purchase any quantity of the goods as the price increases. The point at which the demand curve intersects the price axis, indicates he point where the consumer income cannot purchase any quantity of the goods.
