Document Summary
The paradox of value why is water, which is essential to life, far cheaper than diamonds, which are not essential? is resolved by distinguishing between total utility and marginal utility. We use so much water that the marginal utility from water consumed is small, but the total utility is large. We buy few diamonds, so the marginal utility from diamonds is large, but the total utility is small. The paradox is resolved by distinguishing between total utility and marginal utility. For water, the price is low, total utility is large, and marginal utility is small. For diamonds, the price is high, total utility is small, and marginal utility is high. But marginal utility per dollar is the same for water and diamonds. The supply of water is perfectly elastic, so the quantity of water consumed is large and the consumer surplus from water is large.
