摘要：Costs-benefits analyses enable public or private decision-makers to rationalise their choices. The process is apparently transparent and egalitarian, as the preferences of every individual are aggregated in the same way. However, when they include non-market components assessed through the preferences of the population, individuals are limited in the expression of their preferences by their income and by their subsistence needs. We explore the consequences of these constraints on the preference elicitation process and on the monetary valuation of non-market goods. Results show that they implicitly favour the preferences of high-income individuals. Whether the elicited monetary valuations should be corrected when considering individual preferences remains an open issue.
