- Which of the following statements is a positive economic statement, even if it might be factually incorrect?
Answer: Reducing the capital gains tax rate will result in a higher level of business investment.
A positive statement is one that can be tested against evidence, regardless of whether it is true or false. The claim that reducing the capital gains tax will increase business investment is a testable hypothesis. Economists can study data to support or refute it. The other statements are normative because they are based on values or ethics ('morally obligated,' 'fair tax system,' 'unethical') and cannot be proven or disproven by facts alone.
- A researcher concludes a study by writing, "The data show a strong positive correlation between a country's level of economic freedom and its citizens' self-reported happiness. This evidence supports the view that governments should adopt policies that enhance economic freedom."
This conclusion is questionable because it:
Answer: makes a normative leap from a positive correlation to a policy prescription.
The primary issue is the jump from a positive finding to a normative prescription. The first part of the statement is positive (describing a correlation found in data). The second part is normative (stating what governments 'should' do). Even if the correlation is causal, one cannot conclude what policy should be adopted without making a normative judgment that maximizing citizen happiness is the primary goal and that it outweighs other potential goals that might be harmed by enhancing economic freedom. While A is a valid general concern in economics, the more direct flaw here is the positive-normative leap.
- Which of the following statements moves from a positive observation to a normative conclusion?
Answer: Income inequality has increased in the last decade, which suggests that our economic system is failing the poor.
This statement begins with a positive observation ('Income inequality has increased'), which is a testable fact. It then draws a normative conclusion from this fact ('our economic system is failing the poor'), which is a value judgment. Choice A contains two positive statements. Choice C contains two positive statements. Choice D contains a positive statement and a normative statement, but they are presented as two separate, potentially contradictory points, not a logical progression.
- An economist writes, "The principle of comparative advantage demonstrates that two countries can both benefit from trade, even if one is more productive in all goods. Therefore, all barriers to free trade should be eliminated."
What is the logical flaw in this argument as it is presented?
Answer: It moves from a positive statement about the potential gains from trade to a normative conclusion without addressing other values.
The first sentence is a positive statement derived from economic theory. The second sentence is a normative conclusion. The flaw is that the argument jumps from 'can benefit' (positive) to 'should eliminate' (normative) without considering other potential goals or values, such as national security, income distribution, or protecting infant industries, which might be negatively affected by free trade. Economics can describe the trade-offs, but the choice of which goal to prioritize is normative.
- An economist is studying income inequality. Which of the following research questions represents a positive, rather than normative, line of inquiry?
Answer: What has been the effect of technological change on the wages of low-skilled workers over the past 30 years?
Positive economics deals with 'what is' and can be answered by appealing to facts and evidence. The question about the effect of technological change on wages is a positive question that can be investigated empirically. The other questions involve normative judgments about what is 'equitable,' what 'should' be prioritized, and what is 'too much' to tolerate.
- Read the following headline from a financial newspaper: "GDP Grew at a Disappointing 2% Rate Last Quarter." What does this headline contain?
Answer: A positive statement about the GDP growth rate, combined with a normative judgment about that rate.
The headline has two parts. 'GDP Grew at a... 2% Rate Last Quarter' is a positive statement; it is a piece of data that can be verified. The word 'Disappointing' is a normative judgment. It reflects an opinion that 2% growth is not good enough. While it might reflect expectations, calling it a disappointment is a value-laden interpretation, not an objective fact.
- Which of the following statements is a normative statement?
Answer: The current official poverty line is set too low to reflect a decent standard of living.
Statement D is normative because it involves a value judgment about what constitutes a 'decent standard of living' and whether the poverty line is 'too low.' This cannot be proven or disproven by facts alone. Statements A, B, and C are all positive statements. They are factual claims about the poverty rate, its calculation methodology, and its limitations, all of which can be verified with evidence.
- A labor market analyst makes four statements. Which statement is positive?
Answer: A 10% increase in the minimum wage is projected to decrease employment for teenagers by 1-3%.
The statement in C is a positive one. It is a prediction about the relationship between two variables (minimum wage and teen employment) that can be tested with data. It describes 'what is' or 'what is predicted to be'. The other statements are normative, as they are based on value judgments about what is a 'living wage,' what companies 'ought' to do, and what is 'unfair.'
- Two politicians are debating a proposed carbon tax. Politician A says, "This tax will disproportionately burden low-income families." Politician B replies, "We have a moral obligation to future generations to address climate change." Which statement correctly classifies their arguments?
Answer: Politician A is making a positive argument, while Politician B is making a normative one.
Politician A's statement is positive. It makes a testable claim about the distributional impact of the tax—one can analyze data to see which income groups would pay a larger percentage of their income. Politician B's statement is normative. It is based on a value judgment ('moral obligation') and prescribes a course of action based on ethics, which cannot be scientifically tested.
- The council member's argument rests on both a positive and a normative premise. What is the normative premise?
Answer: Forward-thinking projects that reduce congestion and create jobs are desirable for the city.
The claims about reducing congestion and creating jobs are positive statements (predictions that are, in principle, testable). The normative premise is the underlying value judgment that these outcomes are good and that the city 'ought to' fund projects that achieve them. This statement prescribes what the city should value and do.
- An economic consultant tells a client, "Our analysis indicates that if you lower the price of your product by 10%, your total revenue will increase. Therefore, you should lower your price." The consultant's advice contains:
Answer: A positive statement about price elasticity and a normative statement about business strategy.
The first part of the statement, 'if you lower the price... your total revenue will increase,' is a positive claim. It is a testable prediction based on an (implicit) analysis of the price elasticity of demand. The second part, 'Therefore, you should lower your price,' is a normative recommendation. It assumes the client's goal is to maximize revenue and prescribes an action to achieve it.
- Consider the statement: "To achieve allocative efficiency, an economy must produce at the point where the marginal benefit of the last unit produced equals its marginal cost." This statement is best described as:
Answer: Positive, because it defines a technical condition within an economic model.
This statement is positive. It is the definition of allocative efficiency within economic theory. It doesn't say that an economy should achieve allocative efficiency (that would be normative). It simply states the conditions under which that state exists, as defined by the model. It's a statement about the internal logic of the theory, similar to saying 'A triangle is a shape with three sides.' That the goal itself might be debated (B) or agreed upon (D) doesn't change the nature of the definitional statement itself.
- Which of the following best describes the two statements?
Answer: Statement I is positive because it is a testable hypothesis, while Statement II is normative because it is a value-based prescription.
Statement I is a positive statement. It makes a claim about the cause-and-effect relationship between a tariff and steel prices, which can be empirically tested. Statement II is a normative statement. It uses the word 'should' to advocate for a specific policy based on the value judgment that protecting domestic jobs is a desirable goal.
- A financial analyst says, "Based on historical data, a 1% increase in the federal funds rate has, on average, been followed by a 0.5% decrease in the inflation rate within 12 months. This relationship is not strong enough to justify harming the labor market with a rate hike now."
Which part of the analyst's statement is a positive economic statement?
Answer: The observation linking a past change in the interest rate to a subsequent change in inflation.
The positive part of the statement is the claim about the historical correlation between the federal funds rate and the inflation rate. This is a statement of fact based on data that can be verified or falsified. The parts about the relationship being 'not strong enough' and the policy 'harming the labor market' involve normative judgments about acceptable trade-offs and what constitutes harm.
- An economist states, "For a country to maximize its long-run economic growth, it ought to invest heavily in education and technology." How should this statement be classified?
Answer: As a positive statement that specifies a condition required to achieve a particular goal, not a statement of value.
This is a subtle but important distinction. The statement is not prescribing that maximizing growth should be the goal (which would be normative). Instead, it is making a positive, testable claim about the means to achieve a given goal. The 'ought to' here means 'is required to,' describing a cause-and-effect relationship, much like saying 'to bake a cake, you ought to use flour.' It's a conditional positive statement.
- How should the historian's statement be characterized?
Answer: As positive, because it reports factual information about a historical event and the beliefs of economists.
The entire statement is positive. It makes two testable claims: one about the level of tariff rates (a historical fact) and another about what economists believed and believe (a fact about the state of professional opinion). It does not say the policy should not have been enacted or that it was 'bad'; it simply reports the consensus view of its effect. This is a subtle trap, as the topic (a policy widely seen as a mistake) is value-laden, but the statement itself is factual.
- A central bank governor states, "Our mandate is to maintain price stability. Therefore, we must raise interest rates to combat the current inflation rate of 5%." The validity of the governor's conclusion depends on an unstated premise. Which of the following best represents this unstated positive premise?
Answer: Raising interest rates is an effective mechanism for reducing the rate of inflation.
The governor's argument is: Premise 1 (normative/goal): We must maintain price stability. Conclusion (normative): We must raise interest rates. To get from the premise to the conclusion requires a linking premise about how the world works. That link is the positive statement that raising interest rates actually causes inflation to fall. Options A, B, and D are all normative statements about goals, values, or responsibilities.
- An economist testifies before Congress: "My research indicates that a 20% tariff on imported automobiles would save approximately 5,000 U.S. manufacturing jobs but would cost U.S. consumers an average of $2,000 per new vehicle. In my view, the cost to consumers is an unacceptable price to pay to save those jobs."
How can the economist's testimony be best described?
Answer: It consists of positive analysis regarding the effects on jobs and prices, followed by a normative conclusion about the policy's desirability.
The economist first presents positive analysis: the testable claims that the tariff will save a certain number of jobs and cost consumers a certain amount of money. Then, the economist makes a normative judgment by stating that the trade-off is 'unacceptable.' This final part is a value judgment about which outcome is more important, not a statement that can be tested against data.
- Which of the following statements about market outcomes is strictly positive?
Answer: In the presence of a negative externality, the equilibrium output of a competitive market exceeds the socially optimal quantity.
Statement C is a positive statement derived from standard economic theory. It describes a testable feature of a market model with externalities. The term 'socially optimal' is used here in a technical, positive sense to mean the level of output that maximizes total surplus, not as a subjective value judgment. Statement A is normative ('unfair'). Statement B has a normative component ('undesirable'). Statement D is a normative prescription ('should intervene').
- Which of the following correctly analyzes the economic advisor's statement?
Answer: The statement contains a positive claim about the effect of a price ceiling and a normative judgment about the policy's fairness.
The advisor makes two distinct claims. The first, 'implementing a price ceiling... will lead to shortages,' is a positive statement. It is a testable prediction based on economic theory. The second, 'this policy would be unjust,' is a normative statement. It is a value judgment about the fairness of the outcome and cannot be empirically tested.
