Assume that consumers consider rice and potatoes to be substitutes, so that when the price of rice rises, consumers purchase less rice and more potatoes. When the CPI is computed following the increase in the price of rice, it takes into account

the increase in the price of rice.

Because the CPI is based on a fixed basket of goods, the introduction of new goods and services in the economy causes the CPI to overestimate the cost of living. This is so because

when a new good is introduced, it gives consumers greater choice, thus reducing the amount they must spend to maintain their standard of living.

Fundamentally, economics deals with

scarcity

does not involve mathematics.

Jackie, a Canadian citizen, works only in the United States. The value of the output she produces is

included in U.S. GDP, but it is not included in U.S. GNP.

Over the last few decades, Americans have chosen to cook less at home and eat more at restaurants. This change in behavior, by itself, has

increased measured GDP by the value added by the restaurant's preparation and serving of the meals.

A tradeoff exists between a clean environment and a higher level of income in that

laws that reduce pollution raise costs of production and reduce incomes.

GDP excludes most items that are produced and sold illegally and most items that are produced and consumed at home because

measuring them is so difficult.

The loss of potential gain from other alternatives when one alternative is chosen is called

opportunity cost

Billie Jean has $120 to spend and wants to buy either a new amplifier for her guitar or a new mp3 player to listen to music while working out. Both the amplifier and the mp3 player cost $120, so she can only buy one. This illustrates the basic concept that

A Korean steel company produces steel in the United States, with some of its steel being exported to other nations and some of it being sold within the United States. If the prices of this steel increase, then

the GDP deflator and the CPI will both increase.
