Take the following as truth: For example, adjusting for age differences between subjects in the economic studies and those affected by air pollution may imply the need to adjust the $6 million VSL downward, but the involuntary nature of air pollution-related risks and the lower level of risk-aversion of the manual laborers in the labor market studies may imply the need for upward adjustments.
Then the following statement: "Older people are at greater risk of health problems due to pollution." is true, false, or inconclusive?
Answer: Inconclusive
