Positive and Normative Economics
Economics is often divided into two types of analysis: positive and normative. Positive economics is objective and fact-based, describing and explaining economic phenomena as they are. It focuses on cause-and-effect relationships and can be tested against data (e.g., 'An increase in the minimum wage will cause unemployment to increase'). Normative economics is subjective and value-based, focusing on what the economy 'should be' like. It involves value judgments and opinions, and cannot be proven true or false by facts alone (e.g., 'The government should raise the minimum wage').

In this model, the economist assumes that consumer income, the price of public transportation, and the availability of electric cars all remain unchanged. Which fundamental methodological principle does this economist's assumption illustrate?
The Scientific Nature of Economics
Evaluating an Economic Conclusion
Because economists use sophisticated mathematical models and statistical analysis, their conclusions about cause and effect have the same level of certainty as those derived from controlled experiments in the natural sciences.
Match each methodological term used in economic inquiry with its corresponding description.
Arrange the following steps of a typical economic inquiry into the correct logical sequence, from the initial stage to the final one.
An economist observes a strong positive correlation between the number of ice cream shops in a city and the city's crime rate. Based on this observation alone, the economist concludes that the presence of ice cream shops causes an increase in crime. What is the most significant methodological flaw in this conclusion?
The Role of Simplification in Economic Inquiry
An economist aims to determine the causal effect of a new job training program on the wages of unemployed workers. A city randomly offers the program to 5,000 unemployed individuals (the treatment group) but not to another 5,000 (the control group). The economist will compare the average wages of both groups one year later. Which statement best evaluates the methodological soundness of this research design for establishing causality?

The statement, 'The current national unemployment rate of 3.7% is too high and should be lowered through government intervention,' is a positive economic statement because it refers to a verifiable statistic.
Dissecting an Economic Argument
An economic statement that can be tested and validated against data, such as 'A rise in interest rates will decrease consumer borrowing,' is an example of ______ economics.
An economic advisor is preparing a report for a government official about a proposed carbon tax. The report is structured in two main parts. Part 1 estimates the likely reduction in carbon emissions, the impact on gasoline prices, and the potential revenue generated. Part 2 argues that implementing this tax is the most equitable way to address climate change and that the revenue ought to be used to fund renewable energy projects. How would you best characterize the two parts of this report?
