Scarcity exists
Correct Answer
C. In all countries in the world.
Explanation
Scarcity exists in all countries in the world because it is a fundamental economic concept that arises due to the limited availability of resources compared to the unlimited wants and needs of individuals and society as a whole. Regardless of the level of wealth or development of a nation, there will always be scarcity because resources are finite. This means that people will always have to make choices and trade-offs in order to satisfy their needs and wants, leading to the existence of scarcity in all countries.

Which of the following would eliminate scarcity as an economic problem?
Correct Answer
D. None of the above.
Explanation
None of the options mentioned in the question would eliminate scarcity as an economic problem. Scarcity is a fundamental concept in economics that refers to the limited availability of resources relative to unlimited human wants. While moderation of competitive instincts and the discovery of new energy reserves may alleviate certain aspects of scarcity, they cannot completely eliminate it. Similarly, although steady productivity growth can increase the availability of goods and services, it does not eliminate scarcity entirely. Therefore, none of the options provided would completely eliminate scarcity as an economic problem.
3.
Which of the following is not a resource?
Correct Answer
C. Money
Explanation
Money is not considered a resource because it is not a factor of production. While money can be used to acquire resources, it is not a resource itself. Resources refer to the inputs used in the production of goods and services, such as land, labor, and capital. Money is a medium of exchange and a store of value, but it does not have inherent productive capabilities like the other options listed.

Correct Answer
C. People making choices because of the problem of scarcity
Explanation
Economics is the study of how individuals, households, and societies make choices in the face of limited resources.

Microeconomics approaches the study of economics from the viewpoint of
Correct Answer
A. Individuals or specific markets
Explanation
Microeconomics focuses on the behavior and decision-making of individuals, households, and firms, as well as the interactions between buyers and sellers in specific markets. It analyzes how individuals allocate their resources, make choices, and respond to changes in prices. By studying the microeconomic level, economists can understand how individual actions and market interactions shape the overall economy. This approach allows for a detailed examination of specific markets and their impact on the larger economy, making it the correct answer.

Correct Answer
A. Macroeconomics
Explanation
The review of the performance of the U.S. economy during the 1990's is primarily the concern of macroeconomics because macroeconomics focuses on the overall behavior and performance of the entire economy. It examines factors such as GDP, inflation, unemployment, and government policies that impact the economy as a whole. In contrast, microeconomics focuses on individual economic agents, such as households and firms, and their behavior in specific markets. Since the question asks about the performance of the entire economy, macroeconomics is the appropriate field of study.

An economic theory claims that a rise in gasoline prices will cause gasoline purchases to fall, ceteris paribus. The phrase “ceteris paribus” means that
Correct Answer
A. Other relevant factors like consumer incomes must be held constant
Explanation
The phrase "ceteris paribus" means that other relevant factors like consumer incomes must be held constant. This means that in order to accurately test the theory that a rise in gasoline prices will cause gasoline purchases to fall, all other factors that could potentially influence gasoline purchases, such as consumer incomes, must be kept unchanged. By isolating the effect of gasoline prices on purchases and holding all other factors constant, the theory can be accurately tested.
8.
An economist notices that sunspot activity is high just prior to recessions and concludes that sunspots cause recessions. The economist has
Correct Answer
A. Confused association with and causation
Explanation
The economist has confused association with causation. This means that the economist is assuming that because sunspot activity is high just prior to recessions, sunspots must be the cause of recessions. However, this conclusion is based on a correlation between the two variables and does not necessarily imply a causal relationship. It is possible that there is another underlying factor that is causing both the increase in sunspot activity and the occurrence of recessions. Therefore, the economist's conclusion is not supported by evidence and is a result of misunderstanding the distinction between association and causation.

Which of the following is a statement of normative economics?
Correct Answer
A. The minimum wage is good because it raises wages for the working poor

This statement is an example of normative economics because it presents a value judgment about the minimum wage. It states that the minimum wage is good because it raises wages for the working poor, indicating a belief about what should be considered desirable or beneficial in the economy.

Select the normative statement that completes the following sentence: If the minimum wage is raised rapidly, then
