 Risk-benefit analysis (RBA), also called cost-benefit analysis (CBA) is a collection of decision-aiding techniques that weigh advantages against disadvantages in numerical terms. In a typical risk-benefit analysis, multi-dimensional problems are reduced to a single dimension. This is achieved by assigning monetary values to all potential outcomes. Usually, uncertain outcomes are evaluated according to the expected utility model. This means that the disvalue of a risk is obtained by multiplying the probability of the undesired event by a monetary value representing its severity (Sen 2000; Sunstein 2005).
