a.You are an environmental economist for the San Joaquin Air Pollution Control District. You are assigned to measure the Yosemite National Park visitors' WTP for reducing ozone pollution by 50% in the San Joaquin Valley to improve visibility in the Yosemite National Park. What type of regression models (ex, OLS, Logit, Quantile, etc.) would you use for Single-Bound CVM, Double-Bound CVM, and Single-Site TCM? Briefly explain why.

b.Based on a hedonic price model in 2022, the coefficient for the ozone variable (in ppm) is estimated at 25,000 in linear regression and the average property value in the San Joaquin Valley is $500,000. The number of residential properties in the San Joaquin Valley is 1,000,000. What is the benefit of ozone pollution control on properties in the San Joaquin Valley (by 50% or by 0.08 ppm (from 0.16 ppm to 0.08 ppm))?
