Question 1

Which of the following statements best illustrates the fallacy of composition?

Accepted Answer

The fallacy of composition is the error of assuming that what is true for a member of a group is true for the group as a whole. Choice A illustrates this fallacy by suggesting that if one person stands up at a baseball game to see better, then if everyone stands up, they will all see better, ignoring that everyone's view would actually remain obstructed or unchanged.

Question 2

Which of the following is a statement of positive economics?

Accepted Answer

This statement is a positive economic statement because it is a statement of cause and effect. It predicts that an increase in tax rates will lead to a reduction in unemployment. It can be tested and proven or disproven. The other statements are normative economic statements because they express opinions or value judgments about what should be done.

Question 3

Economic theory asserts that manufacturers are willing to sell fewer units of output as the price of a good decreases, ceteris paribus. However, as the price of computers decreased throughout the 1990s, more computers were sold. Which of the following best explains the apparentconflict between theory and data

Accepted Answer

The apparent conflict between theory and data can be explained by changes in variables other than price, such as technological advancements, increased demand due to the internet, or changes in consumer preferences, which are not accounted for by the ceteris paribus assumption.

Question 4

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 will be better off." These statements demonstrate:

Accepted Answer

The statements demonstrate the fallacy of composition, which assumes that what is true for one person or group is also true for the entire population or group. In this case, it assumes that if one team is better off by acquiring better players, then all teams will be better off by doing the same. However, this may not necessarily be true as there are limits to the number of good players available, and some teams may not be able to afford them, leading to uneven outcomes.

Question 5

The term ceteris paribus means that:

Accepted Answer

Ceteris paribus means "all other things being equal" or "all else constant", which implies that the effect of a change in one variable is being analyzed while holding all other relevant variables constant. Therefore, choice C is the best answer as it states that all other variables except the ones specified are assumed to be constant.

Question 6

Which of the following statements best illustrates the fallacy of composition?

Accepted Answer

The fallacy of composition is the error of assuming that what is true for a member of a group is true for the group as a whole. Option D illustrates this fallacy by suggesting that if one person talks loudly, they are heard better, but incorrectly assumes that if everyone talks loudly, the same benefit applies to all.

Question 7

The importance of the ceteris paribus assumption is that it:

Accepted Answer

The ceteris paribus assumption allows one to isolate the relationship between two variables by assuming that all other relevant variables are held constant. This enables one to analyze the relationship between the two variables apart from the influence of other variables. Therefore, the correct option is C.

Question 8

Which of the following is true of hypothesis and theory?

Accepted Answer

A hypothesis is a proposed explanation for a phenomenon or observation, which is then tested through experiments or data analysis. If the hypothesis is supported by the evidence, it may become a theory, which is a well-substantiated explanation for a wide range of phenomena. Therefore, a theory may result from a tested and confirmed hypothesis.

Question 9

A leading game console manufacturer reduces the price of its flagship product by 10 percent. Holding other things such as income and preferences constant, which of the following is the most likely group behavior prediction?

Accepted Answer

The price reduction is expected to increase the quantity of game consoles demanded (demand curve shifts rightward) as the lower price makes the product more affordable for existing and potential customers. This assumes that other things, such as income and preferences, remain constant. The other options are less likely as there is no evidence to suggest that quality will be reduced or that there will be no impact on purchase patterns. Group behavior can be predicted for consumer goods, as long as the ceteris paribus assumption holds, which means that other things such as income and preferences are held constant.

Question 10

Which of the following statements best illustrates the fallacy of composition?​

Accepted Answer

The fallacy of composition involves assuming that what is true for an individual will also be true for a group. Choice A illustrates this fallacy by suggesting that if individual wealth leads to individual betterment, then universal wealth would lead to universal betterment, ignoring potential broader economic implications such as inflation.

Question 11

Which of the following is a difference between positive economics and normative economics?

Accepted Answer

Positive economics is concerned with describing and explaining economic phenomena as they are, without making value judgments. Normative economics, on the other hand, involves making value judgments and formulating opinions about what economic policies and outcomes should be. Therefore, option A is correct as it highlights the key difference between the two branches of economics.

Question 12

Which of the following is a statement of positive economics?

Accepted Answer

The answer of Which of the following is a statement...

Question 13

Suppose it is observed in a school that students who sit at the back of a classroom, on average, receive lower grades in economics than the rest of the class. This leads to the teachers at the school assuming that sitting at the back rows leads to lower grades. This is an example of:

Accepted Answer

The observation of a correlation between sitting at the back of the classroom and receiving lower grades in economics does not necessarily mean that sitting at the back causes lower grades. There may be other factors at play, such as students who are more likely to sit at the back also being less interested or engaged in the subject. Mistaking correlation for causation is a common logical fallacy.

Question 14

Economists prefer:

Accepted Answer

Economists prefer measuring revealed preferences because it provides a clearer indication of actual behavior instead of just stated intentions. Revealed preferences refer to the choices individuals make based on their available options, which is a more reliable indicator of their preferences compared to just asking them what their preferences are.

Question 15

The fallacy of composition is essentially the error of:

Accepted Answer

The fallacy of composition is the mistake of assuming that what is true of the individual is necessarily true of the whole. It involves generalizing from the individual to the whole, which is not always valid. For example, assuming that if one person stands up at a concert, everyone else should also stand up, can be considered as the fallacy of composition. The other answer choices are not directly related to this fallacy.

Question 16

In the context of correlation and causation, correlation means that:

Accepted Answer

Correlation simply means that two sets of phenomena occur together or are related in some way. It does not necessarily imply a causal relationship between them. Therefore, options B, C, D, and E are incorrect.

Question 17

Ten-year-old Josh observes that people who play football are taller than other people and tells his mom that he is going to play football because it will make him big and strong. Josh is:

Accepted Answer

Josh is mistaking correlation for causation by assuming that playing football causes people to be taller and stronger. There could be other factors that contribute to a person's height and athleticism, such as genetics or nutrition.

Question 18

Which of the following is a statement of positive economics?

Accepted Answer

A statement of positive economics is a statement that can be tested and proven or disproven based on empirical evidence. Choice C is a statement of positive economics because it provides a factual statement about the current rate of unemployment in an economy, which can be verified through data. The other options are not statements of positive economics as they are subjective opinions or comparisons that cannot be objectively tested.

Question 19

The relationship between the price of a good and its quantity supplied can be determined through:

Accepted Answer

The answer of The relationship between the price of a...

Question 20

The fallacy of composition is:

Accepted Answer

The fallacy of composition is the erroneous belief that what is true for an individual must also be true for the group as a whole. It involves attributing aggregate properties to the individual components that make up the group. This fallacy can lead to mistaken conclusions in many areas, including economics, politics, and social psychology.
