Now imagine that a national lawmaker, inspired by the willingness to pay in the state lawmaker's survey, sent a similar email survey to the same group of voters, asking if they would be willing to pay $20 a year to preserve every eagle nesting area in the United States. The questionnaire did not discuss the relative size of the eagle population at Dizzy Mountain to the nationwide eagle population. In this case, 80% said yes. Discuss the scope and warm glow effects that might be present in the survey. What information might the national lawmaker have added to the questionnaire? How would you write the questions to avoid the warm glow or scope effect and to obtain a more accurate estimate of WTP?
