Suppose that an expenditure today of $150,000 on insulating layers to prevent toxic landfill seepage would eliminate $1 million worth of expected health costs 20 years from now. If the social discount rate was 10%, would society be willing to spend the $150,000 today to install the insulating layers? What if the social discount rate was 5%? Now would society be willing to spend the $150,000 today? Assuming the 10% discount rate, what is the most society would be willing to pay today to avoid the $1 million worth of health costs 20 years from now
