Cost-benefit analysis is a method used to evaluate the benefits of a project or decision against its costs. It is commonly used in economics, public policy, and business to determine the economic feasibility of a project or policy. The analysis weighs the potential benefits of a project, such as increased revenue or social welfare, against the costs, such as implementation expenses or negative impacts. By quantifying both the costs and benefits in monetary terms, decision-makers can make more informed choices about whether to proceed with a project or policy. Cost-benefit analysis helps to ensure that resources are allocated efficiently and that decisions are made with consideration of their overall impact on society.
