Social Cost Benefit Analysis

Social Cost Benefit Social Cost Benefit Analysis Analysis

Social Cost Benefit Analysis is a simple and well known concept. It is based on the assessment of the utility of a project for the society as distinct from the financial and economic utility for the promoter group.

While in the latter the focus is limited to financial benefits and costs directly accruing to the enterprise, in social cost benefit analysis the benefits and costs accruing to the society as a whole are considered.

Social Cost Benefit Analysis is to society what profit and loss account is to an enterprise. It is a technique for making enterprise decisions, from society’s stand point.

For exampleFor example

Now, if we think about the impact of soaps and cigars on the society, the question may be –

Does the price of cigar take note of the smoker’s higher probability of cancer?

Does the price of soap take note of the benefits from the use of soap e.g. reduced risk of disease spread increases?

Obliviously, a commercial entrepreneur can't give well answer to these questions.

Methodology of SCBAMethodology of SCBA

While the concept of SCBA is simple, the methodology to be adopted for such an analysis is quite elaborate and intricate. As it is based not only on the consideration of quantitative information but also on qualitative information and subjective judgment.

To suggest a complete methodology of Project appraisal based on the consideration of costs and benefits two teams of economists were constituted, one by the OECD, consisting of IMD Little & JA Mirrlees and the other by the UNIDO consisting of A.K.Sen, P.Dasgupta and Stephen Marglin.

What is SCBA? : What is SCBA? : 

Therefore, to reflect the real value of a project to society, one must consider the impact of the project on society .Thus, when we evaluate a project from the view point of the society (or economy) as a whole, it is called Social Cost Benefit  Analysis (SCBA)/Economic Analysis

Rationale for SCBARationale for SCBAIn SCBA the focus is on social costs and benefits of a project. These often tend to differ from the costs incurred in monetary terms and benefits earned in monetary terms by the project. The principal reasons for discrepancy are:

Market imperfections Externalities Taxes Concern for redistribution Concern for savings Merit wants

Scope of SCBA : Scope of SCBA : 

SCBA can be applied to both public and private investments .

Public Investment: SCBA is important specially for the developing countries where govt. plays a significant role in the economic development.

Private investment: Here, SCBA is also important as the private investments are to be approved by various governmental and Quasi-governmental agencies.

Objectives of SCBA : Objectives of SCBA : The main focus of SCBA is to determine

economic benefits of the project in terms of shadow prices.

The impact of the project on the level of savings and investments in the society.

The impact of the project on the distribution of income in the society; and

The contribution of the project towards the fulfillment of certain merit wants (self-sufficiency, employment etc)

Two Principal Approaches for SCBA : 

UNIDO Approach L-M Approach

UNIDO Approach Stage - 1 : UNIDO Approach Stage - 1 : 

Calculation of financial profitability of the project -A good technical and financial analysis must be done before a meaningful economic (social) evaluation can be made so as to determine financial profitability.

Financial profitability is indicated by the Net Present Value (NPV) of the project, which is measured by taking into Account inputs (costs) and outputs (benefits) at market price.

UNIDO Approach Stage - 2 : UNIDO Approach Stage - 2 : Obtaining the net benefit of the project at

economic (shadow) prices.

The commercial profitability analysis (calculated in stage 1) would be sufficient only if the Project is operated in Perfect market. Because, only in a perfect market, market prices can reflect the social value.

If the market is imperfect (most of the cases in reality), net benefit of the Project is determined by assigning shadow Prices to inputs and outputs. Therefore, developing the shadow prices is very much vital.

UNIDO Approach Stage - 2 : UNIDO Approach Stage - 2 :    Shadow prices reflect the real value of a resource

(input or output) to society as opposed to their financial or market value. Shadow Prices are also referred as economic prices, accounting prices, economic / accounting efficiency prices etc

Use of shadow prices is considered essential particularly due to market imperfections, non-market economy, fiscal policy of the state etc.

For instance, if the pdn cost of 1 ton of a fertiliser is Rs.2000, though it is supplied to the farmers at a subsidised price of Rs. 1500 only, the point of consideration is whether the cost of fertiliser should be taken as Rs.2000, the actual cost of pdn or Rs.1500, its market price.

Shadow Pricing: Basic Shadow Pricing: Basic IssuesIssues

Before we deal with shadow pricing of specific resources, certain basic concepts and issues must be discussed:

1.Choice of Numeraire2.Concept of Tradability3.Source of shadow prices4.Treatment of taxes5.Consumer willingness to pay

1.Choice of Numeraire1.Choice of Numeraire

A unit of account in which the values of inputs and outputs are to be expressed.

Numeraire is determined at

Domestic currency rather than border price. Present value rather than future value. Constant price rather than current price Consumption use rather than investment use.

   2.Concept of Tradability2.Concept of Tradability

A key issue in shadow pricing is whether a good is tradable or not. For a good that is tradable, the international price is a measure of its opportunity cost to the country.

Why? For a tradable good, it is possible to substitute

import for domestic production and vice versa; similarly it is possible to substitute export for domestic consumption and vice versa.

Hence the international price, also referred to as the border price, also represents the ‘real’ value of the good in terms of economic efficiency.

3.Sources of Shadow Pricing3.Sources of Shadow Pricing The UNIDO approach suggests three sources of

shadow pricing, depending on the impact of the project on national economy.If the impact of the project is on -

Basis of shadow pricing is-

Consumption in the economy

Consumer willingness to pay

Production in the economy

Cost of production

International Trade Foreign exchange value

4.Treatment of Taxes4.Treatment of Taxes

When shadow prices are calculated, taxes usually pose difficulties. The general guidelines in the UNIDO approach w.r.t taxes are as follows:

If the project augments domestic production, taxes should be excluded.

If the project consumes existing fixed supply of non-traded inputs, tax should be included .

For fully traded goods, taxes should be ignored

5.Consumer Willingness to Pay 5.Consumer Willingness to Pay (CWP)(CWP)

If the impact of the project is on the consumption in the economy, the basis of shadow pricing is CWP

What a consumer wants to spend for a product or service and what he actually does pay. The difference between CWP and actual payment is called consumer surplus

UNIDO Approach - Stage 2.UNIDO Approach - Stage 2. Shadow Pricing of Specific Shadow Pricing of Specific Resources : Resources : 

1.Tradable inputs and outputs1.Tradable inputs and outputs:- A good is fully traded

a. when an increase in its consumption, results in a corresponding increase in import or decrease in export

b. when an increase in its production, results in a corresponding increase in export or decrease in import.

For fully traded goods, the shadow price is border price translated in domestic currency at market exchange rate.

UNIDO Approach - Stage 2.UNIDO Approach - Stage 2. Shadow Pricing of Specific Shadow Pricing of Specific Resources : Resources : 

2. Non-tradable Inputs and outputs:- A good is non tradable when the following conditions are satisfied

(i) its import price (CIF price) is greater than its domestic cost of production and

(i) its export price ( FOB price) is less than its domestic cost of production.

UNIDO Approach - Stage 2.UNIDO Approach - Stage 2. Shadow Pricing of Specific Shadow Pricing of Specific Resources : Resources : 

Assuming that for a project, one-half of the required input is collected from additional domestic production which has a domestic cost of Rs. 200000 and the rest one half is collected from diversion from other consumers who are willing to pay Rs. 300000.

Therefore the shadow price of the inputs will Be: Cost of production + consumer willingness to pay = Rs (200000+300000) = Rs. 500000

UNIDO Approach - Stage 2.UNIDO Approach - Stage 2.Shadow Pricing of Resources : Shadow Pricing of Resources : 

Assuming that a newly established power station having a total capacity of 100 million units electricity, charges tariff at Rs. 1 for per unit electricity consumption.

The consumers of that particular area are willing to pay Rs. 1.20 for per unit. Therefore, the shadow price is (Rs. 1.20 x10 million) = Rs. 120 million, instead of Rs. 100 million

UNIDO Approach - Stage 2.UNIDO Approach - Stage 2.3.Externalities3.Externalities

An externality, also referred to as an external effect (either beneficial or harmful), is a special class of good which has the following characteristics:

It is not deliberately created by the project sponsor but is an incidental outcome

It is beyond the control of the persons, who are benefited or affected by it

It is not traded in the market place

Examples of ExternalitiesExamples of Externalities

Beneficial effects1. An oil company drilling its own fields may

generate useful information about oil potential in the neighbouring fields.

2. The approach roads built by a company may improve the transport system in the area.

Harmful effects1. A factory may cause environmental pollution

by emitting large volume of smoke and dirt, thereby exposing people in the neighbourhood to health hazards .

2. The location of an airport in a certain area may raise noise levels considerably.

Shadow Pricing of ExternalitiesShadow Pricing of Externalities

Although valuation of external effects is difficult as they are often intangible in nature and there is no market price, their values are estimated by indirect means. For example:

1. The benefit of information provided by the oil field to neighboring oil fields may be equated with what the neighboring oil fields would have spent to obtain such information.

2. The cost of pollution may be estimated in terms of the loss of earnings as a result of damage to health caused by it and the cost of time spent for coping with unhygienic surroundings.

Shadow pricing of labourShadow pricing of labour4.Labour inputs :- The principles of shadow pricing

for goods may be applied to labour as well, though labour is considered to be service. When a project hires labour, it could have 3 possible impacts on the rest of the economy:

I. It may take labour away from other employments

II. It may induce the production of new workers and;

III. It may involve import of workers.

If it’s the 1st case, then the shadow price of labour is equal to what other users of labour are willing to pay for this labour.

In a relatively free market this will be equal to the marginal product of such labour.

Shadow pricing of Capital Shadow pricing of Capital InputsInputs

5.Capital Investment of capital in a project two things happen -

1. Financial resources are converted into physical assets.

2. Financial resources are withdrawn from national pool of savings and hence alternative projects are foregone.

Thus, shadow pricing of capital investment involves two questions:

What is the value of physical assets?What is the opportunity cost of capital(which

reflects the benefit foregone by sacrificing alternative project/s)?

Shadow pricing of Capital InputsShadow pricing of Capital InputsThe shadow price of physical assets is calculated

in the same manner in which the value of any other resource is calculated.

For e.g. If it is a fully traded good, its shadow price is equal to its border price. If it’s a non-traded good its shadow price is measured in terms of cost of pdn

The opportunity cost of capital (shadow price of capital) depends on the source from which the capital has generated.

For e.g. If the capital is generated from the denial of capital to alternative projects, its opportunity cost is the rate of return that would be earned from those alternative projects.

UNIDO Approach...Stage 3: UNIDO Approach...Stage 3: Measurement of the Impact on distributionMeasurement of the Impact on distribution

The purpose of the stages 3&4 are concerned with measuring the value of a project in terms of its contribution to savings and income redistribution. That is to determine the

1. Amount of income gained or lost because of the project by different income groups (such as project other than business, government, workers, customers etc)

2. Evaluate the net impact of these gains and losses on savings

3. Measure the adjustment factor for savings and thus the adjusted values for savings impact

4. Adjust the impact on savings to the net present value calculated in stage two.

UNIDO Approach - Stage 3UNIDO Approach - Stage 3

1.Measurement of Gain or loss : 

The gain or loss to an individual group within the

society as a result of the project is equal to the

difference between shadow price and market price of

each input or output in the case of physical resources

or the difference between price paid and value received

in the case of financial transaction.

For e.g. A mining project requires 1000 labourers at a

wage rate of Rs. 150 per day. These workers were ready

to work for a daily wage of Rs. 100.Therefore, the gain

of the group of 1000 workers from the project (150-

100)x1000 = 50000 per day.

UNIDO Approach - Stage 3UNIDO Approach - Stage 3

2. Savings Impact and its value:

Most of the developing countries face scarcity

of capital. Hence the governments of these

countries are concerned about the impact of a

project on savings and its value thereof.

Stage three of the UNIDO method, concerned with this, seeks to answer the following questions:

Given the income distribution impact of the project what would be its effect on savings?

What is the value of such savings to the society?

UNIDO Approach - stage 3UNIDO Approach - stage 3 Evaluation of the Net Impact on Savings :-

Net savings Impact of the project = ΣΔYi MPSi Here, Δ Yi = change in income of group i as a result of the project MPSi= Marginal Propensity to save a group i

Assuming that the income gained or lost by 4 group is Workers (W) = Rs. 250000 Consumer(C) = Rs. -700000 Project (P) = Rs 1000000 External (E)=Rs.500000

The Marginal Propensity to Save of these four groups is: MPSw=0.04, MPSc=0.25, MPSp=0.4 and MPSe = 0.3

Therefore, the net impact of the project on savings is: {250000 x0.04+(-700000) x 0.25 + 100000 x 0.4 + 500000x0.3} = Rs. 475000

UNIDO Approach - stage 3UNIDO Approach - stage 3 Adjustment Factor for Savings (AFs)Adjustment Factor for Savings (AFs)

AFs measure the percentage by which the social value of investment of one Re. exceeds social value of consumption of one rupee.

Here, MPC = Marginal Propensity to Consume MPS = Marginal Propensity to Saving MPcap = Marginal Productivity of Capital CRI = Consumption Rate of Interest (Social Discount

Rate)

UNIDO Approach - stage 3UNIDO Approach - stage 3 Adjustment Factor for Savings (AFs)Adjustment Factor for Savings (AFs)

Assuming that MPC, MPS, MPcap and CRI of an economy is given: MPC = 70%, MPS = 30%, MPcap=25% and CRI=10% .

Therefore, adjustment factor for savings is AFs.

Adjusted Value of the impact of the project on savings: Adjusted value of Savings = (Net impact on savings X AFs) = Rs. 475000x6 = Rs. 28,50,000

UNIDO Approach - stage 3UNIDO Approach - stage 3

This Rs. 2850000 is now added to the NPV of the project calculated in stage 2(Rs.237.48 crore) .

Therefore, the adjusted NPV at this stage will be Rs. (237.48+.285) = Rs. 237.765 crore

UNIDO Approach Stage 4:UNIDO Approach Stage 4: Income distribution impact Income distribution impact Govt. considers a project as an investment for the

redistribution of income in favour of economically weaker sections or economically backward regions.

This stage provides a value on the effects of a project on income distribution between rich and poor and among regions.

Distribution Adjustment Factor (Weight) is calculated and the impacts of the project on income distribution have been valued by multiplying the adjustment factor with the particular income of a group.

This value will then be added to the net present value re-calculated in stage three to produce the social net present value of the project.

UNIDO Approach Stage 4UNIDO Approach Stage 4 Determination of WeightsDetermination of Weights

If there are only two groups in a society, poor and rich, the

determination of weight is just an iterative process between

the analysts (at the bottom) and the planners (at the top).

This is called "bottom-up" approach.

When more than two groups are involved, weights are

calculated by the elasticity of marginal utility of income.

The marginal utility of income is the weight attached to an

income, where

wi = weight of income at ci level ci = level of income of group i b = base level of income that has a weight of 1 n = elasticity of the marginal utility of income

UNIDO Approach Stage 4:UNIDO Approach Stage 4:

Assuming that the worker group gains an income of Rs. 250000 from a project, the base level of income is Rs. 50000 which has a weight if 1 and elasticity of Marginal Utility of Income is 0.20.

Therefore, weight is value of the impact of the project on income distribution to this group is Rs 250000x0.72 = Rs. 180000

Now this value will be added to the net present value adjusted in stage three. Therefore, Adjusted NPV in this stage will be Rs (237.765x0.018) = Rs. 237.78 crore

UNIDO Approach - Stage 5UNIDO Approach - Stage 5 Adjustment for Merit and Demerit Adjustment for Merit and Demerit

GoodsGoods If there is no difference between the economic value

of inputs and outputs and the social value of those, the UNIDO approach for project evaluation ends at stage four.

In practical, there are some goods (merit goods), the social value of which exceed the economic value (e.g oil, creation of employment etc) and also there are some goods (demerit goods), social value of which is less than their economic value (e.g., cigarette, alcohol, high -grade cosmetics etc)

Adjustment to the NPV of stage 4 is required if there is any difference between the social and economic value

UNIDO Approach - Stage 5 : UNIDO Approach - Stage 5 : 

The procedure for adjusting the difference between social value and economic value are:

1.Estimating the present economic value.

2.Calculating the adjustment factor.

3.Multiplying the economic value by the

adjustment factor to obtain the adjusted value.

4.Adding or subtracting the adjusted value to or

from the NPV of the project as calculated in

stage four.

UNIDO Approach - Stage 5 : UNIDO Approach - Stage 5 : 

An alcohol factory is being constructed. The present economic value of the project is Rs. 237.78 crore (Adjusted NPV up to stage 4).

The output of the project has no social value than its cost of production.

Cost of production is the 60% of the economic price. Therefore, adjustment factor is: ((60/100)-1) = -0.4 Therefore, the adjusted value = (Rs. 237.78 crore x - 0.4) = Rs. -95.11 crore

The NPV of the project in terms of socially acceptable consumption is (Rs. 237.78 - 95.11) = Rs. 142.67 crore.

ConclusionConclusionWhile the adjustment for the difference between

social value and economic value is seemingly a step

in the right direction, it is amenable to abuse. Once

the analyst begins to make a adjustment for social

reasons, projects which are undesirable economically

maybe made to appear attractive after such

adjustment.

While there is no way to prevent such a

manipulation, the stage-by-stage UNIDO approach

mitigates its occurrence by throwing it in sharp

relief.

L-M Approach L-M Approach

I.M.D. Little and James A. Mirrless have developed an approach to SCBA which is famously known as L-M approach.

The core of this approach is that the social cost of using a resource in developing countries differs widely from the price paid for it .

Hence, it requires Shadow Prices to denote the real value of a resource to society

Despite considerable similarities there are certain Despite considerable similarities there are certain differences between the 2 approaches:differences between the 2 approaches:

The UNIDO approach measures costs and benefits in terms of domestic rupees whereas the L-M approach measures costs and benefits in terms of international prices(border prices)

The UNIDO approach measures costs and benefits in terms of consumption whereas the L-M approach measures costs and benefits in terms of uncommitted social income.(L-M Numeraire is present uncommitted social income. L-M methods opt for savings as the yardstick of their entire approach. Present savings is more valuable to them than present consumption since the savings can be converted into investment fore future L-M approach rejects the 'consumption‘) .

The stage-by-stage analysis recommended by the UNIDO approach fosusses on efficiency,savings and redistribution considerations in different stages. The L-M approach, however, tends to view these considerations together.

Social Cost Benefit Analysis Social Cost Benefit Analysis (SCBA)(SCBA)

The resources of input and output of a project are classified into: Labour, Traded goods & Non-traded goods. Therefore, to find out the real value of these resources, the following values are to be calculated.

a. Shadow wage rate (SWR).b. Shadow price of traded goods c. Shadow price of Non-traded goods

a. a. Shadow Wage Rate (SWR)Shadow Wage Rate (SWR)

The shadow wage rate is an important but difficult to determine element in SCBA. It is a function of several factors:

The marginal productivity of labour

The cost associated with urbanisation

The cost of having an additional amount committed

to consumption when the consumption of a worker

increases as a result of the higher income he enjoys

in urban employment.

Shadow Wage Rate (SWR)Shadow Wage Rate (SWR)

L-M suggest the following formula for calculating SWR-

SWR= c`-1\s(c-m)

c`= additional resources devoted to consumption.

1/s = value of a unit of committed resource

m= marginal product of the wage earner.

c = consumption of wage earner

L-M ApproachL-M Approach

b) Shadow price of Traded Goods -Shadow price of traded goods is simply its border or international price. If a good is exported, its shadow price is its FOB Price. If a good is imported, its shadow price is its CIF price. (The logic for using border prices is because it represents the correct social opportunity costs or benefits of using or producing a traded good).

c) Shadow price of Non-traded goods- Non-traded goods are those which do not enter into international trade by their very nature. (e.g., land, building, transportation) Hence, no border price is observable for them.

L-M ApproachL-M Approach Ideally, shadow price of non-traded goods is

defined in terms of Marginal Social Cost (MSC) and the marginal social benefit (MSB).

The MSC of a good is the value in terms of accounting prices of the resources required to produce an extra unit of the good. For e.g. the MSC of a bus trip is roughly equal to the cost of material inputs(fuel, oil, wear&tear of the bus, etc.)

The MSB is the value of an extra unit of the good from the social point of view.

L-M suggest that the monetary cost of non-traded goods be broken down into Labour ---- SWR (Social Wage Rate) Tradable ----- SCF (Social Conversion Factor) Residual components ------(SCF)

L-M ApproachL-M Approach Accounting Rate of Return (ARR):Accounting Rate of Return (ARR):This is the rate used for discounting social

profits. Experience is the best guide to the choice of ARR .

ARR should be such that all mutually compatible projects with positive present social value can be undertaken
