If an economy is operating inside its production possibilities curve for consumer goods and capital goods, it can only produce more consumer goods by producing fewer capital goods. can only produce more capital goods by producing fewer consumer goods. can produce more of both consumer goods and capital goods by using resources that are currently idle. must improve its technology to produce more output.

choices that are made in seeking the best use of resources.

more consumer goods can only be produced at the cost of fewer capital goods.
Joe sold gold coins for $1,000 that he bought a year ago for $1,000. He says, "At least I didn't lose any money on my financial investment." His economist friend points out that in effect he did lose money because he could have received a 3 percent return on the $1,000 if he had bought a bank certificate of deposit instead of the coins. The economist's analysis in this case incorporates the idea of opportunity costs. marginal benefits that exceed marginal costs. imperfect information. normative economics.
opportunity costs.
Consumers spend their incomes to get the maximum benefit or satisfaction from the goods and services they purchase. This is a reflection of resource scarcity and the necessity of choice. purposeful behavior. marginal costs that exceed marginal benefits. the trade-off problem that exists between competing goals.
purposeful behavior.
The output of digital music players should be reduced if marginal benefits exceed marginal costs. reduced if marginal costs exceed marginal benefits. increased if marginal costs exceed marginal benefits. reduced to zero if their unit costs exceed the unit costs of alternative products.
reduced if marginal costs exceed marginal benefits.
When an economy is operating under conditions of full employment, the production of more of commodity A will mean the production of less of commodity B because of the law of increasing opportunity costs. economic wants are insatiable. resources are limited. resources are specialized and only imperfectly substitutable.
resources are limited.
Economics may best be defined as the interaction between macro and micro considerations. social science concerned with how individuals, institutions, and society make optimal choices under conditions of scarcity. empirical testing of value judgments through the use of logic. study of why people are rational.
