Cost Benefit Analysis: Evaluating Economic Decisions for Society

The video tutorial explains cost benefit analysis, a technique to evaluate social benefits and costs of economic decisions. It covers the importance of considering both private and external costs and benefits, using an example of building a new airport. Challenges in estimating externalities and the concept of discounting future values to present value are discussed. The tutorial concludes with an evaluation of the method's effectiveness and limitations.

What is the primary goal of cost benefit analysis?

• To estimate the financial profit of a project

• To compare social benefits and costs of a decision

• To determine the environmental impact of a project

• To calculate the tax implications of a decision

Which of the following is NOT a component of social costs?

• Social costs

• Government subsidies

• External costs

• Private costs

In the airport example, what is considered an external cost?

• Revenue from increased tourism

• Noise pollution affecting local residents

• Landing fees from airlines

• Cost of building the airport

Why is it challenging to estimate the cost of noise pollution?

• It is a direct cost to the government

• It has no impact on property values

• It is difficult to quantify how much it bothers individuals

• It affects everyone equally

What does the term 'discounting' refer to in cost benefit analysis?

• Increasing future revenues

• Ignoring external costs

• Adjusting future costs and benefits to present value

• Reducing the price of a project

How is net present value (NPV) calculated?

• By dividing total benefits by total costs

• By subtracting future costs from future benefits

• By adding all future revenues

• By subtracting the present value of costs from the present value of benefits

What does a positive net present value indicate?

• The project should be abandoned

• The present value of costs is greater than benefits

• The project is financially viable

• The project has no external costs

Which factor can complicate the discounting process?

• Consistent future revenues

• Fixed project costs

• Changing interest rates over time

• Stable interest rates

What is a potential downside of conducting a cost benefit analysis?

• It always leads to project approval

• It guarantees accurate results

• It requires no skilled personnel

• It can be costly and time-consuming

Why might a government decide not to proceed with a project despite a positive NPV?

• There are unquantifiable externalities

• The cost benefit analysis was inexpensive

• The project has no social benefits

• The project is too small
