-
- 7.
Economists use different assumptions when studying the short-run and long-run effects of a change in the quantity of money.
-
True
-
False
Correct Answer
A. TrueExplanation
Economists use different assumptions when studying the short-run and long-run effects of a change in the quantity of money. This is true because the short-run effects of a change in the quantity of money are often characterized by sticky prices and wages, which means that they do not adjust immediately to changes in the money supply. In the short-run, changes in the quantity of money can have real effects on output and employment. In contrast, the long-run effects of a change in the quantity of money are primarily determined by changes in the price level. In the long-run, prices and wages are more flexible, and changes in the money supply primarily affect the price level rather than real variables.Rate this question:
-
- 8.
Economists use models which are often composed of diagrams and equations.
-
True
-
False
Correct Answer
A. TrueExplanation
Economists use models composed of diagrams and equations to represent and analyze economic situations. These models help economists understand and predict the behavior of individuals, firms, and markets. Diagrams visually represent relationships and interactions between economic variables, while equations mathematically express these relationships. By using models, economists can simplify complex economic systems and make predictions about how changes in variables will affect outcomes. Therefore, the statement "Economists use models which are often composed of diagrams and equations" is true.Rate this question:

All models are built with assumptions.
-
True
-
False
Correct Answer
A. TrueExplanation
Models are constructed based on certain assumptions, which are simplified representations of reality. These assumptions help to simplify complex systems and make them more manageable for analysis and interpretation. Therefore, it is true that all models are built with assumptions.Rate this question:

The circular-flow diagram dispenses signifcant details but aren't crucial for basic understanding of how the economy is organized.
-
True
-
False
Correct Answer
A. TrueExplanation
The circular-flow diagram is a simplified representation of how goods, services, and money flow in an economy. While it provides important information about the interconnections between households, businesses, and the government, it is not essential for a basic understanding of how the economy is organized. Basic understanding can be achieved by grasping concepts such as supply and demand, the role of prices, and the functions of different economic agents. Therefore, the statement that the circular-flow diagram does not provide crucial details for basic understanding of the economy is true.Rate this question:
-
- 12.
Most economic models are built using diagrams.
-
True
-
False
Correct Answer
A. FalseExplanation
Most economic models are built using tools of mathematics.Rate this question:

The economy can produce at any point on or inside the production possibilties frontier, but it cannot produce at points outside the frontier.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because the production possibilities frontier represents the maximum potential output of an economy given its resources and technology. Any point on or inside the frontier represents a combination of goods and services that can be produced efficiently. However, points outside the frontier are unattainable with the current resources and technology. Therefore, the economy can only produce at points on or inside the production possibilities frontier.Rate this question:
-
- 14.
An outcome is said to be efficient if the economy is getting all it can from the scarce resources it has available.
-
True
-
False
Correct Answer
A. TrueExplanation
Efficiency in an economy refers to the ability to maximize output from limited resources. If an outcome is efficient, it means that the economy is utilizing its scarce resources to their fullest potential, leaving no wasted or unused resources. This implies that the economy is producing the maximum possible output given its available resources, making the statement "True".Rate this question:
-
- 15.
The production possibilities frontier shows the trade-off between the outputs of different goods at a given time, but the trade-off can change over time.
-
True
-
False
Correct Answer
A. TrueExplanation
The production possibilities frontier is a graphical representation of the maximum output combinations of two goods that an economy can produce with its given resources and technology. It illustrates the trade-off between producing different goods at a given time. However, this trade-off is not fixed and can change over time due to various factors such as technological advancements, changes in resource availability, or shifts in consumer preferences. Therefore, it is true that the trade-off depicted by the production possibilities frontier can change over time.Rate this question:
-
- 16.
The production possibilities frontier simplifies a complex economy to highlight some basic put fowerful ideas except:
-
Economic growth
-
Trade-offs
-
Inflation
-
Opportunity cost
-
Scarcity
Correct Answer
A. InflationExplanation
The production possibilities frontier is a graphical representation of the maximum output an economy can produce given its resources and technology. It helps to illustrate the concept of scarcity and trade-offs, as it shows the different combinations of goods and services that can be produced. Economic growth, opportunity cost, and scarcity are all concepts that the production possibilities frontier can effectively highlight. However, inflation is not directly related to the production possibilities frontier as it represents a general increase in prices over time.Rate this question:

Because microeconomics and macroeconomics adress different questions, each field has its own set of models.
-
True
-
False
Correct Answer
A. TrueExplanation
Microeconomics and macroeconomics are two branches of economics that focus on different aspects of the economy. Microeconomics studies the behavior of individual economic agents such as households and firms, while macroeconomics examines the overall performance and behavior of the entire economy. Due to these different focuses, each field requires its own specific models and theories to analyze and understand the economic phenomena being studied. Therefore, the statement that "each field has its own set of models" is true.Rate this question:

DEMAND CURVE There is a simple way to tell when it is necessary to shift a curve: whena variable that is not named on either axis changes, the curve shifts.
-
True
-
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that when a variable that is not named on either axis changes, it causes a shift in the curve. This means that if a factor or variable that affects the demand curve, such as income or consumer preferences, changes, it will result in a shift of the demand curve. Therefore, the statement that it is necessary to shift a curve when a variable that is not named on either axis changes is true.Rate this question:

A graph where in the Y axis is: Risk of Cancer and the X axis: Number of Lighters in the House is an example of Omitted Variables.
-
True
-
False
Correct Answer
A. TrueExplanation
This statement is true because the given graph shows a relationship between the risk of cancer and the number of lighters in the house. However, it does not consider other variables that could affect the risk of cancer, such as smoking habits, exposure to carcinogens, or genetic factors. Omitted variables refer to factors that are not included in the analysis but could have an impact on the relationship being studied. Therefore, this graph is an example of omitted variables as it only considers one variable (number of lighters) while ignoring other potential factors that could influence the risk of cancer.Rate this question:
