সারসংক্ষেপ	Willingness to pay (WTP) is an economic valuation method that elicits what individuals or society are willing to spend for a health benefit or to avoid a health risk. Rooted in contingent valuation (Carson & Louviere, 1980s), WTP is used to monetize health outcomes for cost-benefit analysis and to infer implicit cost-effectiveness thresholds from actual healthcare spending patterns. Unlike revealed preference (observing actual spending behavior), WTP uses stated preferences—surveys asking respondents: 'How much would you pay for this health improvement?'	Cost-benefit analysis compares the total monetary value of benefits produced by a program against its total monetary costs, reporting net present value (NPV) or benefit-cost ratio (BCR). Rooted in welfare economics and used extensively in public policy (transportation, environmental, education, health), CBA answers the question: 'Is this program worth doing from a societal perspective?' Unlike cost-effectiveness analysis, CBA monetizes both costs and benefits, enabling comparison across disparate program types.
