IGCSE ECONOMICS
As a person buys more of a good, the total utility they get from it rises. But it does not rise by
the same amount each time. In fact, it rises by a smaller amount with each good consumed.
The extra utility gained from consuming one more unit is called marginal utility.

Economists define normal goods as having a positive income elasticity.

The rules of politics are not always the same as the rules of economics. In discussions of setting budgets for government agencies, there is a strategy called closing the Washington Monument. When an agency faces the unwelcome prospect of a budget cut, it may decide to close a high-visibility attraction enjoyed by many people (like the Washington Monument). Explain in terms of diminishing marginal utility why the Washington Monument strategy is So misleading. Hint: If you are really trying to make the best of a budget cut, should you cut the items in your budget with tile highest marginal utility or line lowest marginal utility? Does the Washington Monument strategy cut the items with the highest marginal utility or line lowest marginal utility?
Would you expect total utility to rise or fall with additional consumption of a good? Why?
