This is the end of the test. When you have completed all the questions and reviewed your answers, press the button below to grade the test.

What causes the demand for a good to increase?

The demand for a normal good increases if income increases. The demand for an inferior good decreases if income increases. Expected future income and expected future prices influence demand today. For example, if the price of a computer is expected to fall next month, the demand for computers today decreases.

How does an increase in income affect the demand for most goods?

The income effect identifies the change in consumers' demand for goods and services based on their incomes. In general, as one's income rises, they will begin to demand more goods. Similarly, A decrease in income results in lower demand.

When the price of a good increases demand for the good will?

An increase in the price of a good will increase demand for its substitute, while a decrease in the price of a good will decrease demand for its substitute.

What is the claim that with other things being equal the quantity demanded of a good falls when the price of that good rises?
