Determinantion of visitors' willingness to pay to enter Karagol Natural Park of Ankara, Turkey

The objectives of this study were to assess visitors' attitudes, if visitors would be willing to pay to enter Lake Karagol, and what factors affect their decision to pay. The contingent valuation method was used to estimate the economic value of the lake by assessing willingness to pay (WTP). Double dichotomous questions were used in the survey. Respondents were first asked whether or not they would be willing to pay the starting bid. They could either answer in the affirmative (that is, accepted bid) or in the negative (that is, reject the starting bid). The average WTP for an entrance fee was found to be about USD 0.22 for all observations when zero bids were included, and about USD 4.40 when zero bids were excluded. Result of the probit model showed that respondents with a higher income, respondents who were young, and the working status of the respondents had significant impacts on the probability of the WTP.
