1. Cost Benefit Analysis 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 1

2. Cost-Benefit Analysis (CBA) Objective: To understand the principles, methods, and applications of cost-benefit analysis in evaluating the economic efficiency and desirability of projects or policies. Introduction: Definition of cost-benefit analysis and its role in decision-making processes related to public investments, policies, and projects. Explanation of why CBA is considered a valuable tool for assessing the net societal benefits of alternative courses of action. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 2

3. Resource Allocation: Assist decision-makers in allocating scarce resources efficiently by comparing the costs and benefits of competing projects or policy options. Prioritize investments and interventions that yield the highest net benefits to society. Risk Management: Identify and quantify potential costs, benefits, and risks associated with projects or policies. Inform risk mitigation strategies and contingency planning to minimize adverse outcomes. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 3

4. Accountability and Transparency: Enhance accountability and transparency in decision-making by providing a systematic and rigorous framework for evaluating projects or policies. Enable stakeholders to assess the rationale and justification for investment decisions based on objective criteria. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 4

5. Key Components of Cost-Benefit Analysis: Identification of Costs and Benefits: Identify and quantify all relevant costs and benefits associated with the project or policy under consideration. Include direct and indirect costs, as well as tangible and intangible benefits. Monetization of Costs and Benefits: Express costs and benefits in monetary terms to facilitate comparison and aggregation. Use market prices, shadow prices, or valuation techniques to assign monetary values to non-market goods and services. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 5

6. Discounting and Time Preference: Discount future costs and benefits to account for the time value of money and individuals' time preferences. Apply an appropriate discount rate to reflect the opportunity cost of capital and the social rate of time preference. Sensitivity Analysis: Conduct sensitivity analysis to assess the robustness of CBA results to changes in key assumptions, parameters, or scenarios. Identify sources of uncertainty and variability in cost and benefit estimates and their implications for decision-making. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 6

7. Challenges and Considerations: Valuation of Intangible Benefits: Address challenges in valuing intangible benefits such as environmental quality, health improvements, and social well-being. Adopt appropriate valuation methods and techniques, such as contingent valuation or stated preference surveys. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 7

8. Distributional Impacts: Consider distributional impacts and equity concerns in CBA, including the distribution of costs and benefits among different population groups or regions. Incorporate equity considerations into project design and implementation to mitigate adverse distributional effects. Ethical and Social Considerations: Recognize ethical considerations and social values in CBA, including intergenerational equity, fairness, and social justice. Engage stakeholders in the CBA process to ensure their perspectives and concerns are considered in decision-making. 11-03-2024 Dr.P.VIGNESH KUMAR,PROFESSOR IN CHEMISTRY,DEPARTMENT OF S&H 8
