CEA - Certified Economic Analyst Policy Evaluation and Analysis Questions and Answers — Questions and Answers
Question 1: An economic analyst is conducting a cost-benefit analysis for a proposed public infrastructure project. The project has a present value of total benefits estimated at $80 million and a present value of total costs estimated at $65 million. Based on the standard decision rule, what is the Net Present Value (NPV) of the project and what is the appropriate recommendation?
- NPV is $145 million; accept the project.
- The NPV cannot be determined without the discount rate.
- NPV is $15 million; accept the project. (Correct answer)
- NPV is -$15 million; reject the project.
Correct answer: NPV is $15 million; accept the project.
The Net Present Value (NPV) is calculated by subtracting the present value of costs from the present value of benefits (NPV = PV(Benefits) - PV(Costs)). In this case, NPV = $80 million - $65 million = $15 million. The standard decision rule for a cost-benefit analysis is to accept projects that have a positive NPV, as this indicates that the societal benefits outweigh the costs.
Question 2: A national government wants to evaluate the impact of a new nationwide carbon tax policy on industrial emissions. The policy was implemented for the entire country at the same time, making a traditional control group unavailable. However, detailed emissions data is available for many years prior to the policy's implementation. Which evaluation method is most appropriate for this scenario?
- Randomized Controlled Trial (RCT)
- Difference-in-Differences (DiD)
- Regression Discontinuity Design (RDD)
- Interrupted Time Series (ITS) (Correct answer)
Correct answer: Interrupted Time Series (ITS)
Interrupted Time Series (ITS) analysis is the most suitable method here. ITS is a quasi-experimental design that specializes in evaluating the impact of a population-level intervention implemented at a specific point in time. It uses the long-term data from before the intervention to establish a trend, which is then compared to the trend after the intervention to estimate the policy's effect. RCT and DiD are not feasible as they require a control group, and RDD requires a specific cutoff point for eligibility, which is not present here.
Question 3: An analyst uses a difference-in-differences (DiD) model to assess the impact of a regional training program on workers' wages. The analysis compares the change in wages for workers in the region with the program (treatment group) to the change in wages in a similar, neighboring region without the program (control group). For the DiD estimate to be valid, what is the critical 'parallel trends assumption'?
- The wage levels in both regions must have been identical before the program started.
- In the absence of the training program, the wage trends in the treatment and control regions would have been the same. (Correct answer)
- The economic structures of both regions must be completely identical.
- The control group's wages must remain static throughout the entire analysis period.
Correct answer: In the absence of the training program, the wage trends in the treatment and control regions would have been the same.
The parallel trends assumption is the cornerstone of the DiD method. It posits that the treatment and control groups' outcomes would have followed the same trend over time had the treatment not occurred. This assumption allows the analyst to attribute any deviation from this common trend in the treatment group post-intervention to the effect of the policy itself. It does not require the levels of the outcome to be the same, only their trends.
Question 4: Which of the following best describes the primary purpose of conducting a Regulatory Impact Analysis (RIA)?
- To guarantee that a new regulation will increase government tax revenue.
- To provide a legal justification for regulations after they have been implemented.
- To systematically assess the potential benefits, costs, and effects of a proposed regulation to inform decision-making. (Correct answer)
- To exclusively focus on the financial costs imposed on private businesses.
Correct answer: To systematically assess the potential benefits, costs, and effects of a proposed regulation to inform decision-making.
A Regulatory Impact Analysis (RIA) is a systematic policy tool used to provide a detailed and objective appraisal of the potential impacts of a new regulation before it is implemented. The main goal is to ensure that regulations are welfare-enhancing from a societal viewpoint by comparing all potential benefits and costs, thereby promoting evidence-based and efficient policy-making.
Question 5: A city is considering a policy to reduce noise pollution from a nearby airport. To value this non-market good for a cost-benefit analysis, analysts conduct a survey asking residents near the airport how much they would be willing to pay in higher property taxes for the implementation of new noise-reduction technology. This survey-based valuation technique is known as:
- Hedonic Pricing
- Travel Cost Method
- Contingent Valuation (Correct answer)
- Revealed Preference
Correct answer: Contingent Valuation
Contingent Valuation is a survey-based method used to place a monetary value on non-market goods, such as environmental amenities. It operates by creating a hypothetical market and directly asking individuals to state their willingness to pay for the good in question. Hedonic pricing would use housing price differences, the travel cost method would analyze visitor expenses, and revealed preference is a broader category of methods based on observed behavior, not surveys.
Question 6: A policy analyst is comparing two potential social policies. Policy A aims to maximize the sum of all individuals' utilities, while Policy B is designed to maximize the well-being of the worst-off person in society. Policy B's objective is most consistent with which social welfare function?
- Utilitarian
- Rawlsian (Maximin) (Correct answer)
- Pareto
- Kaldor-Hicks
Correct answer: Rawlsian (Maximin)
The Rawlsian social welfare function, based on John Rawls' 'maximin' principle, states that social welfare is determined by the welfare of the least advantaged member of society. Therefore, a policy that seeks to maximize the minimum level of utility aligns with the Rawlsian framework. A Utilitarian function corresponds to Policy A, while Pareto and Kaldor-Hicks are efficiency criteria rather than distributive social welfare functions.
