The discounting principle in social cost-benefit analysis refers to the practice of assigning lower value to future costs and benefits compared to present costs and benefits. This principle recognizes that people generally prefer immediate benefits over delayed benefits and immediate costs over delayed costs. Therefore, when conducting a cost-benefit analysis for a project or policy that has long-term impacts, economists apply a discount rate to adjust the future costs and benefits to their present value. This discount rate reflects the time preference of individuals and society, and it is used to calculate the net present value of the project or policy. By discounting future costs and benefits, the analysis takes into account the opportunity cost of using resources in the present rather than in the future, and it helps decision-makers prioritize projects or policies based on their long-term economic efficiency.
