| Summary: | Through a survey the authors study
willingness to pay for improvements in air quality in Sofia,
Bulgaria. Using a stochastic payment car approach - asking
respondents the likelihood that they would agree to pay a
series of prices - they estimate the distribution of
willingness to pay various prices. They find that people in
Sofia are willing to pay up to about 4.2 percent of their
income for a program to improve air quality. The income
elasticity of willingness to pay for air quality improvements is about 27 percent. For comparison, they also used the referendum contingent valuation approach. Results
from that approach yielded a higher estimate of willingness
to pay. |
