If there are few goods available to buy - consumers are prepared to pay a high price for them BECUASE their marginal Utility is high

If goods are plentiful - then consumers are only prepared to pay a low price BECUASE the last one consumed has low marginal utility

Question 25

How does the law of diminishing marginal utility explain why the demand curve is downward sloping

Answer 25

The higher the quantity bought, the lower the marginal utility (the utility from the last one) derived from consuming the product So buyers will only pay Low prices for relatively high amounts purchased - but they will pay higher prices if the quantity available for sale is lower
