Question 1

A theory asserts that consumers will purchase less of a good at higher prices than they will at lower prices, ceteris paribus. However, when the average price of cars increased throughout the 1990s, more cars were purchased. Which of the following best explains the apparent conflict between theory and data?

Accepted Answer

The apparent conflict between the theory and data can be explained by the fact that other factors such as income growth and changes in consumer preferences could have influenced the demand for cars during the 1990s. Therefore, the ceteris paribus assumption may not have been valid, leading to the observed increase in car purchases despite higher prices.

Question 2

"When one basketball team spends a large sum of money acquiring better players, it is better off. If all teams do the same thing, all of them are better off." These statements demonstrate:

Accepted Answer

This statement demonstrates the fallacy of composition, which assumes that what is true for one part of a system must necessarily be true for the system as a whole. In this case, it assumes that the benefits of one team spending large sums of money on acquiring better players must necessarily apply to all teams if they were to follow suit. However, this assumption overlooks the potential negative consequences that could arise if all teams were to adopt this strategy, such as inflation in player salaries and reduced competitive balance.

Question 3

"Ceteris paribus" means:

Accepted Answer

"Ceteris paribus" is a Latin phrase meaning "holding other things constant." It is often used in economics to isolate the impact of a specific variable, by assuming that all other factors remain fixed. Therefore, the correct answer is D.

Question 4

The fallacy of composition is essentially the error of:

Accepted Answer

The fallacy of composition involves assuming that something true for an individual or part of a group must also be true for the group as a whole. This can be an error because variables that operate on a smaller scale may not translate to a larger scale, and generalizing in this way can lead to incorrect conclusions. The other answer options are describing different types of errors or fallacies in economic reasoning.

Question 5

Which of the following best illustrates the fallacy of composition?

Accepted Answer

The fallacy of composition is assuming that what is true for an individual will also be true when applied to a group. In choice A, the idea that if one person stands up, they see better, but if everyone stands up, the benefit does not scale up and everyone's view does not improve similarly, illustrates this fallacy. Choices B, C, and D do not illustrate the fallacy of composition because the outcomes scale up with the number of participants.

Question 6

In the discussion of correlation and causation, correlation means:

Accepted Answer

Correlation refers to a relationship or association between two variables, but it does not necessarily imply causation. In other words, just because two variables are correlated, it does not mean that one causes the other. There could be other variables or factors that affect both variables, or the relationship may be purely coincidental. Therefore, option A is the best choice. Option B suggests that there is a causal relationship, which contradicts the definition of correlation. Option C is too strong and absolute because it does not allow for other possible explanations. Option D is an unrelated and humorous statement, but it does not provide a valid explanation for the concept of correlation and causation.

Question 7

Your mother tells you, "Watching ten hours of TV per day will make you stupid." This is a positive statement because:

Accepted Answer

The statement is a proposition that can be tested, as it can be investigated whether watching ten hours of TV per day has a negative impact on cognitive abilities.

Question 8

The importance of the ceteris paribus assumption is that it:

Accepted Answer

The ceteris paribus assumption allows economists to isolate two variables and analyze their relationship independent of the influence of other variables. This is important for building economic models and making causal inferences. It is not related to normative economics, generalization, or suspending the economy.

Question 9

A leading game-console manufacturer slashes the price of its flagship product by ten percent. Holding other things such as income and preferences constant, which of the following is the most likely group behavior prediction?

Accepted Answer

A price reduction of a flagship product is likely to increase demand and sales, assuming all other factors are constant. Therefore, more game consoles are likely to be sold at a lower price. Option A is incorrect because a price reduction usually influences purchase behavior. Option B is incorrect because there is no mention of a reduction in quality. Option D is incorrect because group behavior can be predicted in certain situations.

Question 10

Which of the following statements can explain why an association between Event A and Event B may not imply causality from A to B?

Accepted Answer

All of the options listed can explain why an association between Event A and Event B may not imply causality from A to B, including coincidence, a third variable causing both events, and causality running from B to A instead. Therefore, the best answer is D.

Question 11

A theory asserts that manufacturers are less willing to sell units of output as the price of a good decreases, ceteris paribus. However, as the price of computers fell throughout the 1990s, more computers were sold. Which of the following best explains the apparent conflict between theory and data?

Accepted Answer

It is likely that other variables, such as advancements in computer technology and an increase in consumer demand for computers, were changing and had a greater impact on the quantity of computers sold than the decrease in price. Therefore, the theory of manufacturers being less willing to sell units of output as the price decreases may still hold true, but other factors must be considered in analyzing the market for computers.

Question 12

Which of the following best illustrates the fallacy of composition?

Accepted Answer

The fallacy of composition is assuming that what is true for a part will also be true for the whole. In choice A, the assumption that if one person leaves early to avoid traffic, it benefits them, and thus if everyone did the same, it would benefit everyone, illustrates this fallacy. This overlooks the fact that if everyone leaves early, the same traffic congestion issues would likely occur, just at an earlier time.

Question 13

Which of the following best illustrates the fallacy of composition?

Accepted Answer

The fallacy of composition occurs when someone assumes that what is true of the parts must be true of the whole. In this case, the speaker assumes that because talking louder will help them be heard, it will also help everyone else be heard. However, if everyone talks louder, it may create a noisy and chaotic environment making it harder for anyone to be heard.

Question 14

"I woke up earlier today to beat other fishermen to the fish and yet I caught the same number of fish at 5 am.as I did at noon." Which of the following best explains this occurrence?

Accepted Answer

The passage states that the narrator caught the same number of fish at 5 am as he did at noon. This suggests that the time of day does not affect the number of fish that can be caught. Choice A is the only choice that provides a possible explanation for this occurrence.

Question 15

In Europe, birth rates have fallen as the stork population decreased. This is likely

Accepted Answer

This statement is an example of confusing correlation and causation because the falling stork population and falling birth rates are simply happening at the same time, but one does not necessarily cause the other.

Question 16

The fallacy of composition is:

Accepted Answer

The fallacy of composition is the erroneous belief that what is true for the individual will also be true for the group. This is often not the case, as aggregate behaviors and outcomes can differ from individual behaviors and outcomes.

Question 17

Many people have heard that the stock market rises when a team from the National Football Conference (NFC) wins the Super Bowl, and falls when a team from the American Football Conference (AFC) is victorious. If you conclude that there is a causal relationship between the outcome of the Super Bowl and stock prices, you probably are:

Accepted Answer

The correlation between the outcome of the Super Bowl and stock market performance is likely coincidental, and there is not a direct causal relationship between the two. Confusing correlation with causation is a common logical fallacy that occurs when two variables are observed to have a relationship, but one does not directly cause the other.

Question 18

The fallacy of composition is the erroneous view that:

Accepted Answer

The fallacy of composition occurs when someone assumes that what is true for an individual is true for the group as a whole. This is incorrect because what is true for an individual may not be true for the group. For example, one person standing up at a concert may have a better view, but if everyone stands up, no one will have a better view and the overall experience will be worse.

Question 19

In a congressional debate about agricultural price supports, senators, members of congress, and other experts made the following four statements. Which of these is a normative statement?

Accepted Answer

Statement A is a normative statement because it expresses an opinion about what should be done based on a value judgment. It is subjective and cannot be proven or disproven by data or facts. Statements B, C, and D are all positive statements because they make factual claims that can be tested and proven using data and evidence.

Question 20

If individuals who sit in the back of the classroom receive lower grades on average than the rest of the class, does that mean that sitting in the back of a classroom causes one to perform poorly on exams?

Accepted Answer

The fact that there is a correlation between sitting in the back of the classroom and receiving lower grades does not necessarily mean that sitting in the back causes one to perform poorly on exams. There may be other factors, such as a lack of engagement or distractions, that are associated with sitting in the back and also contribute to lower grades. Therefore, it is important to consider other variables before concluding that there is a causal relationship between sitting in the back of the classroom and academic performance.
