Bayesian estimation approach for farmers’ willingness to pay for irrigation tank maintenance: The case of irrigation tank in Tamil Nadu

Non-market-based valuation methods, such as the contingent valuation method, emphasise the estimation of mean or median willingness to pay. This paper employs a Bayesian approach to estimate a quantile binary regression and WTP distribution in a contingent valuation framework. The findings suggest that interpreting technical non-market valuation studies using alternative quantiles framed in the supermajority notion provides a plausible interpretation. The majority of the farmers (44%) are willing to pay about Rupees 2000 to 4000 per year for the tank.
