ANALYSIS COST – BENEFIT

(CBA)PONNADA PUSPALATHA

Assistant Professor

ADITYA INSTITUTE OF TECHNOLOGY AND MANAGEMENT(AUTONOMOUS)Tekkali, Srikakulam.

Page 2: Cost benefit analysis (environmental impact assessment)

IntroductionCost-benefit analysis is a set of practical

procedures for guiding public expenditure decisions.

Page 3: Cost benefit analysis (environmental impact assessment)

We want our environment to be clean and safe.

But ‘how much’ clean and safe ?

How to measure environmental benefits and costs ?

Page 4: Cost benefit analysis (environmental impact assessment)

Total Cost

Total Benefit

Maximum Net Benefit

Q1 Q*

Q0 Q2

Most Efficient Resource Distribution

• Our aim is to attain the ‘most efficient’ resource distribution.

•We will select the option with the ‘maximum’ net benefit

Page 5: Cost benefit analysis (environmental impact assessment)

Project cost =

cost of resources + cost imposed on third parties

Include only incremental costs

Do not include – interest payments, depreciation

Project costs

Page 6: Cost benefit analysis (environmental impact assessment)

Project benefitsUse and Non-use values

Use values = all use benefits to man

Non-use values =

Direct or Indirect use benefits + option values + existence values

Page 7: Cost benefit analysis (environmental impact assessment)

Environmental valuesEnvironmental Values

Use Values

Direct Use Values (Timber, Food,

Recreation)

Indirect Use Values

( Nutrient Recycling)

Non-use Values

Optional Use

Values(Gene pool)

Bequest Values

(Conservation

Rainforests)

Existence values(Conservation of Tiger)

Page 8: Cost benefit analysis (environmental impact assessment)

Secondary benefitsResult from primary benefits of the project

e.g. project > higher wages to employees > higher expenditure > improve quality of life

Not included in CBA

Viewed as transfer between communities rather than net addition to community income

Page 9: Cost benefit analysis (environmental impact assessment)

Option valuesRisk is attached to all decisions

Uncertainty about demand and supply in future

Pay more to insure demand or supply

Option value =

value that an individual is willing to pay in excess to expected use value to preserve an asset

Page 10: Cost benefit analysis (environmental impact assessment)

Uncertainty continued ….

Project A

Project B

ENPV

$ 1.5 M

P = 1

P = 0.5

P = 0.5$ 5 M

$ - 1 M

$ 2 M

$ 2.5 M

$ 1.5 M

$ - 0.5 M

Steps in CBA

• Role:1• Environmental components (i) for presenting various option (ii) Selecting among them

• Role: 2(i) Environmental mitigation

measures converted into costs (ii) Management plans

are useful

Living organisms

Air Water Soil

i.e, environmental impacts (of a project) are accounted

Page 12: Cost benefit analysis (environmental impact assessment)

Role 3: Economic assesment of the environmental impacts of a project.

Drawbacks: 1. Impacts are to be: Transformed and stated

in clear monetary terms

2. Not useful for small scale development projects.

3. Not possible to find economic value on environmental losses or gains that resulted from a development project.

Not always possible

Intangibles like health – Related impacts of industrial developments

Page 13: Cost benefit analysis (environmental impact assessment)

Site evaluation together with Major design options:Within (i) economic limitationsIi) technical limitations

That give LEAST ECONOMIC COST to the community

Thank You !
