01 If black income is not included in official data, what caution is needed in NNP-based policy analysis?
Answer and explanation
Correct answer: A. Official NNP may not provide a complete picture of the economy
Explanation: Black income refers to income that is concealed from official authorities and therefore may be absent from national-income statistics. If such income is excluded, measured NNP can be lower than the economy’s actual income. Hence, policymakers should treat official NNP as an incomplete estimate, consider under-reporting, and avoid drawing welfare or policy conclusions without supporting evidence.
