Managerial Economics
Assignment A
Question 1: Distinguish between the following:
(i) Industry demand and Firm (Company) demand,
(ii) Short-run demand and Long run demand,
(iii) Durable goods’ demand and Non-durable goods
demand.
Answer (1 i):
Company demand denotes the demand for the products by a particular
company or the firm whereas Industry demand is the demand for product by
an industry as a whole.
Under monopoly, company demand is the same as industry demand while in
all other types of markets the two demands are different.
In perfect competition company demand is completely divorced from
industry demand.
In monopolistic competition, the industry demand curve has little meaning.
Answer (1 ii):
The short run is a period of time in which the quantity of at least one input
is fixed and the quantities of the other inputs can be varied.
The long run is a period of time in which the quantities of all inputs can be
varied.
Short Run: Some inputs variable, some fixed. New firms do not enter the
industry, and existing firms do not exit.
Long Run: All inputs variable, firms can enter and exit the market place.

There is no fixed time that can be marked on the calendar to separate the
short run from the long run. The short run and long run distinction varies
from one industry to another.
Answer (1 III):
A. Non durable goods are those which can be used only once while durable goods
are those which can be used over and over again.
B. Sale of non durable goods are generally for meeting current demand, while sale
of durable goods add to the stock of existing goods whose services are used
over a long period of time.
Question 2: What are the problems faced in determining the demand
for a durable good? Illustrate with example of demand for
households refrigerator or television set.
Answer:
In the case of durable goods, however, there are some challenges associated with
identifying the demand. We do not get to observe frequent purchases of the same
type of durable goods by the same customer, nor do we expect many to ever
purchase the same item again, such as in the case of television set or refrigerator.
Then the price variation given from the longitudinal data of a customer’s purchase
history is, in general, within a category of similar products rather than for the same
product. The sparse purchases make it difficult to make conclusions about
individual customer’s preferences and price sensitivities, especially specific to the
individual product item level.
Potential preference changes during the long inter-purchase times associated with
durable goods also contribute to the challenge in estimating customer preferences.
In addition, when price variation over time is used to estimate demand/price
Sensitivity, changes in price can be confounded with many other factors.
Suppose we are going to buy a television or fridge then we will not go straight to
the market and buy the item. We have to do certain calculation. What is our need
associate to that product. How big fridge we need? Which company we have to
choose? Do we have the space to keep that fridge, or we have the fund to buy a
certain product. What are the features that we are looking for, so in buying
household items we have certain difficulty into determining the need.

Question 3: Analyze the method by which a firm can allocate the
given advertising budget between different media of advertisement.
Answer
In order to keep the advertising budget in line with promotional and
marketing goals, an advertiser should answer several important budget
questions:
1. Who is the target consumer? Who is interested in purchasing the
advertiser's product or service, and what are the specific
demographics of this consumer (age, employment, sex, attitudes,
etc.)? Often it is useful to compose a consumer profile to give the
abstract idea of a "target consumer" a face and a personality that can
then be used to shape the advertising message.
2. Is the media the advertiser is considering able to reach the target
consumer?
3. What is required to get the target consumer to purchase the product?
Does the product lend itself to rational or emotional appeals? Which
appeals are most likely to persuade the target consumer?
4. What is the relationship between advertising expenditures and the
impact of advertising campaigns on product or service purchases? In
other words, how much profit is earned for each dollar spent on
advertising?
Answering these questions will provide the advertiser with an idea of the
market conditions, and, thus, how best to advertise within these conditions.
Once this analysis of the market situation is complete, an advertiser has to
decide how the money dedicated to advertising is to be allocated.
There are several allocation methods used in developing a budget. The most
common are listed below:
• Percentage of Sales method
• Objective and Task method
• Competitive Parity method
Unauthorized copying, selling and redistribution of the content are prohibited. This
material is provided for reference onl Page 4
• Market Share method
• Unit Sales method
• All Available Funds method
• Affordable method
PERCENTAGE OF SALES METHOD Due to its simplicity, the percentage of
sales method is the most commonly used by small businesses. When using
this method an advertiser takes a percentage of either past or anticipated
sales and allocates that percentage of the overall budget to advertising.
Critics of this method, though, charge that using past sales for figuring the
advertising budget is too conservative and that it can stunt growth.
However, it might be safer for a small business to use this method if the
ownership feels that future returns cannot be safely anticipated. On the
other hand, an established business, with well-established profit trends, will
tend to use anticipated sales when figuring advertising expenditures. This
method can be especially effective if the business compares its sales with
those of the competition (if available) when figuring its budget.
Question 4: What kind of relationship would you postulate between
short-run and long-run average cost curves when these are not U-
shaped as suggested by the modern theories?
Answer:
Of late it is observed from certain empirical evidence that the LAC curves are more
L-shaped rather than U-shaped. In the event where we assume that there is no
technological progress, the LAC is U-shaped but in the context of modern times
where technological revolution is inherent, the empirical studies have shown
that there is greater likelihood of prevalence of LAC to be L-shaped rather than U-
shaped. The LAC is characterized by a rapid downward slope in the early part of the
curve, whereas the curve, may remain flat or slope gently downwards in later
stages.

The above fig shows that initially the firm is producing OQ at the minimum
possible average cost on LAC, i.e. at OA. When demand increases, the firm
produces OQ2 at the average cost of OB on LAC1. But if we assume that
technological progress takes place then the new LAC will be LAC2 and the
output OQ2 would be produced at the average cost of OC which is less than
ob. Thus, introduction of technology reduces the long run average cost.
LAC1, LAC2, LAC3 and LAC4 are possible long run average cost curves with
different technology. When we join the minimum points of LAC curves we
get the LAC which acquires the L-shape in the long run under condition of
changing technology. The L-shape of the LAC curve is also the outcome of
the process of ‘learning’ in course of production over a period of time. Thus
new technology and process of learning influence the shape of LAC curve.
We may conclude that “While the short run average cost must be U-shaped,
the long run average cost curve can be either U-shaped or L-shaped.”

Question 5: How do demand forecasting methods for new products
vary from those for established products?
Answer
Demand Forecasting: It is a process of estimating the future demand or
sales pattern of a firm by taking into account the past information, opinion of
industry observers & evolving consumption pattern for a desired time period.
Demand forecasting of a new product
• Projecting demand for a new product is different from those of
established products. This requires an intensive study of economic and
competitive characteristics of product. Forecasting methods need to be
tailored to a particular product
1. Product lifecycle analysis – Many products generally have
characteristics known as perishable distinctiveness. This means that a
product is distinct when it degenerates over the years into a common
product. This innovation of new product and its degeneration into a
common product is
Unauthorized copying, selling and redistribution of the content are prohibited. This
material is provided for reference onl Page 7
Forecasting demand for new products:
 Project the demand for a new product as an outgrowth of an existing old product.
 Analyze the new product as a substitute for some existing product or service.
 Estimate the rate of growth and ultimate level of demand for the new product on the
basis of the pattern of growth of the established products.
 Estimate the demand by making direct enquiries from the ultimate purchasers, either by
use of the samples or on a full scale.
 Offer the new product for sale in a sample market, e.g., by direct mail or through one
multiple shop organization.
 Survey consumers’ reaction to a new product indirectly through the eyes of specialized
dealers who are supposed to be informed about consumers’ needs and alternative
opportunities.

Assignment - B
Question 1: What are the different methods of measuring national income? Which
methods have been followed in India?
Answer:
National Income is the money value of all goods and services produced in a country
during a year. National income shows the economic position of a nation. The basic
objective of an economy is to achieve economic progress. This is achieved by
coordinating natural resources, human resources, capital, technology etc. National
income will help to assess and compare the progress achieved by a country over a
period of time.
We can calculate national income by following any one of these methods. Considering
the nature and requirements of the economy one or more methods are used for
calculating national income. The three methods used for calculating national income
are:
A Production method
B Income method
C Expenditure method
A. Production method
This method is based on the total production of a country during a year. First of all
production units are classified into primary, secondary and tertiary sectors. Then we
identify the various units that come under these sectors. We estimate the goods and
services produced in each of these sectors. The sum total of products produced in
these three sectors is the total output of the nation. The next step is to find out the value
of these products in terms of money. The money sent by Indian citizens working abroad
is also added to this. Now we get the gross national income.
GNI = Money value of total goods and services + Income from abroad.
This method helps us to find out contributions of various sectors to national income.
B. Income Method
Factors of production together produce output and income. The income received by the
factors of production during a year can be obtained by adding rent to land, wages to
labour, interest to capital and profit to organisations. This will be equal to the income of
the nation. In other words, total income is equal to the reward given to various factors of

material is provided for reference onl Page 9
production. By adding the money sent by the Indian citizens from abroad to the income
of the various factors of production, we get the gross national income.
GNI = Rent + Wage + Interest + Profit + Income from abroad.
This method will help us to know the contributions made by different agents like
Landlords, labourers, capitalists and organizers to national income.
C. Expenditure Method
National income can also be calculated by adding up the expenditure incurred for goods
and services. Government as well as private individuals spend money for consumption
and production purposes. The sum total of expenditure incurred in a country during a
year will be equal to national income.
GNI = Individual Expenditure + Government Expenditure.
This method will help us to identify the expenditure incurred by different agents.
Any one of the above methods can be used for calculating national income.
Production method = Income method = Expenditure method.
Today national income in India is calculated and published by the Central Statistical
Organization. All the three methods are used for calculating national income in India.
Question 2: What do you understand by the investment multiplier? In what way
does it defend the policy of public works on the part of the state during business
depression?
Answer: Investment multiplier is simply the multiplier effect of an injection of investment
into an economy. In general, a multiplier shows how a sum injected into an economy
travels and generates more output.
For example if you buy $100 worth of chips. Say the stall owner saves $10 and spends
$90 on burgers. Then the burger stall owner saves 10% that is $9 and consumes the
rest ($81) on cheese, and so on... Each $ received 10% is saved (marginal propensity
to save- MPS) and 90% consumed (marginal propensity to consume - MPC). This
eventually results in 100/(1-.9)=$1000 worth of expenditure in the economy. The
multiplier=1/(1-MPC).

The investment multiplier is simply the same idea applied to an increase in investment
as opposed to consumption above. Using consumption just makes it easier to
understand; investment multiplier is just the same.
Question 3: Discuss the various phases of business cycle:
(i) Are cyclical fluctuations necessary for economic growth?
(ii) Suggest appropriate fiscal and monetary policies for depression.
Answer 3i: The business cycle or economic cycle refers to the ups and downs
seen somewhat simultaneously in most parts of an economy. The cycle
involves shifts over time between periods of relatively rapid growth of output
(recovery and prosperity), alternating with periods of relative stagnation or
decline (contraction or recession). These fluctuations are often measured
using the real gross domestic product. To call those alternances cycles is
rather misleading, as they don't tend to repeat at fairly regular time
intervals. Most observers find that their lengths (from peak to peak, or from
trough to trough) vary, so that cycles are not mechanical in their regularity.
Business cycles are a type of fluctuation found in the aggregate economic
activity of nations that organize their work mainly in business enterprises: a
cycle consists of expansions occurring at about the same time in many
economic activities, followed by similarly general recessions, contractions
and revivals which merge in the expansion phase of the next cycle; this
sequence of changes is recurrent but not periodic; in duration business
cycles vary from more than one year to ten or twelve years; they are not
divisible into shorter cycles of similar character with amplitudes
approximately their own. (Burns and Mitchell)
Actually there are six phases of business cycles counting the peak points
(when booms turns into burst and the troughs).Business cycles are the
recurring rises and falls in overall economic activity as reflected in
production, employment, profits, prices, wages, and other macroeconomic
series. Business cycles are recurring, but non-periodic, and one cycle must
be more than a year, otherwise, it would be considered a seasonal cycle.
Business cycles reflect the inability of the marketplace to accommodate
smoothly such factors as new technologies, changing needs for occupational
skills, shifting markets for new and substitute products, and risks in business
investments. Business cycles can also reflect shortages and high prices

created by external shocks such as war, cutbacks in oil production by the
Organization of Petroleum Exporting Countries (OPEC), bad harvests, and
natural disasters.
Six phases of the business cycle are illustrated: Peak, Recession,
Contraction, Trough, Recovery, and Expansion. One complete cycle can be
measured from Peak-to-Peak or Trough-to-Trough. Beginning with the peak,
the six phases of the business cycle unfold as follows. The Peak is the high
point of continuous expansion just before the downturn in economic activity.
This is followed by a Recession, the immediate downturn in economic activity
after the peak in the business cycle, and represents the downward region of
the cycle from the peak to the trough. If overall activity falls below the
lowest level (i.e., trough) of the previous recession (lower horizontal dotted
line on the graph), then this more severe decline may be referred to as
Contraction.
The Trough is the lowest point of the recession phase of the business cycle
just before economic activity turns upward. Once economic activity turns
upward, the economy is then in Recovery. This phase of the business cycle
immediately follows the trough, and is characterized by the continuous
expansion of economic activity. The economy is in Expansion when overall
activity in the recovery phase exceeds the peak of the previous business
cycle (upper horizontal dotted line).
Sometimes during the upward phase of the business cycle, the expanding
economy may not be increasing production fast enough to absorb those
entering the labor market, and may even result in some of those already
employed being laid off. That is, overall production and unemployment rates
are both rising. This situation is known as a growth recession. If the opposite
occurs, that is, if the economy expands beyond the long- run sustainable
growth rate for a significant period of time, then this period may be
characterized as a boom. Booms are usually followed by a recession.
There may be obvious signs that the economy is in a recession, such as
slack business activity and a rising unemployment rate. We may be affected
personally, by having our workweeks reduced or even by losing our jobs. But
there is also a set of observable measurements of a recession. These
measurements provide the criteria for clearly defining dates for the peak and
the trough.

(ii) Fiscal policy focuses on controlling the government spending in order to
accelerate or retard economic growth. During depression, an expansionary
fiscal policy should be used which aims at increasing government spending
to directly increase investment, employment and thus domestic demand.
Expansionary fiscal policy is either financed through borrowing or tax
increase.
Monetary policy aims at controlling the liquidity in the market to spur up or
slow down the economy. It is implemented primarily through interest rate
control (though there are other ways as well). Usually the central bank is
responsible for fixing the interest rate. During depression, an expansionary
monetary policy is implemented (easy money) which aims to bring down
interest rate or make money cheaper. It is then expected that with cheaper
money, the private sector will increase production, which will increase
employment and then demand.

Case Study
Please read the case study given below and answer questions given at the end.
Electron Control, Inc., sells voltage regulators to other manufacturers, who then
customize and distribute the products to quality assurance labs for their sensitive test
equipment. The yearly volume of output is 15,000 units. The selling price and cost per
unit are shown below:
Selling price $200
Costs:
Direct material $35
Direct labor 50
Variable overhead 25
Variable selling expenses 25
Fixed selling expenses 15 150
Unit profit before tax $ 50
Management is evaluating the alternative of performing the necessary customizing to
allow Electron Control to sell its output directly to Q/A labs for $275 per unit. Although
no added investment is required in productive facilities, additional processing costs are
estimated as:
Direct labor $25 per unit
Variable overhead $15 per unit
Variable selling expenses $10 per unit
Fixed selling expenses $100,000 per year
Question:
Calculate the incremental profit Electron Control would earn by customizing
its instruments and marketing directly to end users.
Answer:
Ans: No of units produced annually =15000
Profit on selling price of 200 is 50 per unit.
So total profit earned is 15000x50= 7, 50,000
If they sell it @ 275 to Q/A labs then:
Added variable Expense=50 per unit
Unauthorized copying, selling and redistribution of the content are prohibited. This
material is provided for reference onl Page 14
Total variable expense = 150 + 50 = 200 per unit.
Total profit per unit = SP – CP
= 275 – 200
= 75 per unit
Added profit per unit= Total profit – profit on SP of 200
= 75 – 50
=25
Total Profit=75X15000=11, 25,000
Net profit = Total profit – Fixed selling expenses.
Net profit =11, 25,000 - 1, 00,000 =10, 25,000.
Incremental profit= 10, 25,000- 7, 50,000= 2, 75,000.

  • 1. Unauthorized copying, selling and redistribution of the content are prohibited. This material is provided for reference onl Page 1 Managerial Economics Assignment A Question 1: Distinguish between the following: (i) Industry demand and Firm (Company) demand, (ii) Short-run demand and Long run demand, (iii) Durable goods’ demand and Non-durable goods demand. Answer (1 i): Company demand denotes the demand for the products by a particular company or the firm whereas Industry demand is the demand for product by an industry as a whole. Under monopoly, company demand is the same as industry demand while in all other types of markets the two demands are different. In perfect competition company demand is completely divorced from industry demand. In monopolistic competition, the industry demand curve has little meaning. Answer (1 ii): The short run is a period of time in which the quantity of at least one input is fixed and the quantities of the other inputs can be varied. The long run is a period of time in which the quantities of all inputs can be varied. Short Run: Some inputs variable, some fixed. New firms do not enter the industry, and existing firms do not exit.

The short run and long run distinction varies from one industry to another. Answer (1 III): A. Non durable goods are those which can be used only once while durable goods are those which can be used over and over again. B. Sale of non durable goods are generally for meeting current demand, while sale of durable goods add to the stock of existing goods whose services are used over a long period of time. Question 2: What are the problems faced in determining the demand for a durable good? Illustrate with example of demand for households refrigerator or television set. Answer: In the case of durable goods, however, there are some challenges associated with identifying the demand. We do not get to observe frequent purchases of the same type of durable goods by the same customer, nor do we expect many to ever purchase the same item again, such as in the case of television set or refrigerator. Then the price variation given from the longitudinal data of a customer’s purchase history is, in general, within a category of similar products rather than for the same product. The sparse purchases make it difficult to make conclusions about individual customer’s preferences and price sensitivities, especially specific to the individual product item level. Potential preference changes during the long inter-purchase times associated with durable goods also contribute to the challenge in estimating customer preferences. In addition, when price variation over time is used to estimate demand/price Sensitivity, changes in price can be confounded with many other factors. Suppose we are going to buy a television or fridge then we will not go straight to the market and buy the item. We have to do certain calculation. What is our need associate to that product. How big fridge we need? Which company we have to choose? Do we have the space to keep that fridge, or we have the fund to buy a certain product. What are the features that we are looking for, so in buying household items we have certain difficulty into determining the need.

This material is provided for reference onl Page 3 Question 3: Analyze the method by which a firm can allocate the given advertising budget between different media of advertisement. Answer In order to keep the advertising budget in line with promotional and marketing goals, an advertiser should answer several important budget questions: 1. Who is the target consumer? Who is interested in purchasing the advertiser's product or service, and what are the specific demographics of this consumer (age, employment, sex, attitudes, etc.)? Often it is useful to compose a consumer profile to give the abstract idea of a "target consumer" a face and a personality that can then be used to shape the advertising message. 2. Is the media the advertiser is considering able to reach the target consumer? 3. What is required to get the target consumer to purchase the product? Does the product lend itself to rational or emotional appeals? Which appeals are most likely to persuade the target consumer? 4. What is the relationship between advertising expenditures and the impact of advertising campaigns on product or service purchases? In other words, how much profit is earned for each dollar spent on advertising? Answering these questions will provide the advertiser with an idea of the market conditions, and, thus, how best to advertise within these conditions. Once this analysis of the market situation is complete, an advertiser has to decide how the money dedicated to advertising is to be allocated. There are several allocation methods used in developing a budget. The most common are listed below: • Percentage of Sales method • Objective and Task method • Competitive Parity method
  • 4. Unauthorized copying, selling and redistribution of the content are prohibited. This material is provided for reference onl Page 4 • Market Share method • Unit Sales method • All Available Funds method • Affordable method PERCENTAGE OF SALES METHOD Due to its simplicity, the percentage of sales method is the most commonly used by small businesses. When using this method an advertiser takes a percentage of either past or anticipated sales and allocates that percentage of the overall budget to advertising. Critics of this method, though, charge that using past sales for figuring the advertising budget is too conservative and that it can stunt growth. However, it might be safer for a small business to use this method if the ownership feels that future returns cannot be safely anticipated. On the other hand, an established business, with well-established profit trends, will tend to use anticipated sales when figuring advertising expenditures. This method can be especially effective if the business compares its sales with those of the competition (if available) when figuring its budget. Question 4: What kind of relationship would you postulate between short-run and long-run average cost curves when these are not U- shaped as suggested by the modern theories? Answer: Of late it is observed from certain empirical evidence that the LAC curves are more L-shaped rather than U-shaped. In the event where we assume that there is no technological progress, the LAC is U-shaped but in the context of modern times where technological revolution is inherent, the empirical studies have shown that there is greater likelihood of prevalence of LAC to be L-shaped rather than U- shaped. The LAC is characterized by a rapid downward slope in the early part of the curve, whereas the curve, may remain flat or slope gently downwards in later stages.

This material is provided for reference onl Page 5 The above fig shows that initially the firm is producing OQ at the minimum possible average cost on LAC, i.e. at OA. When demand increases, the firm produces OQ2 at the average cost of OB on LAC1. But if we assume that technological progress takes place then the new LAC will be LAC2 and the output OQ2 would be produced at the average cost of OC which is less than ob. Thus, introduction of technology reduces the long run average cost. LAC1, LAC2, LAC3 and LAC4 are possible long run average cost curves with different technology. When we join the minimum points of LAC curves we get the LAC which acquires the L-shape in the long run under condition of changing technology. The L-shape of the LAC curve is also the outcome of the process of ‘learning’ in course of production over a period of time. Thus new technology and process of learning influence the shape of LAC curve. We may conclude that “While the short run average cost must be U-shaped, the long run average cost curve can be either U-shaped or L-shaped.”

Answer Demand Forecasting: It is a process of estimating the future demand or sales pattern of a firm by taking into account the past information, opinion of industry observers & evolving consumption pattern for a desired time period. Demand forecasting of a new product • Projecting demand for a new product is different from those of established products. This requires an intensive study of economic and competitive characteristics of product. Forecasting methods need to be tailored to a particular product 1. Product lifecycle analysis – Many products generally have characteristics known as perishable distinctiveness. This means that a product is distinct when it degenerates over the years into a common product. This innovation of new product and its degeneration into a common product is

Analyze the new product as a substitute for some existing product or service. Estimate the rate of growth and ultimate level of demand for the new product on the basis of the pattern of growth of the established products. Estimate the demand by making direct enquiries from the ultimate purchasers, either by use of the samples or on a full scale. Offer the new product for sale in a sample market, e.g., by direct mail or through one multiple shop organization. Survey consumers’ reaction to a new product indirectly through the eyes of specialized dealers who are supposed to be informed about consumers’ needs and alternative opportunities.

This material is provided for reference onl Page 8 Assignment - B Question 1: What are the different methods of measuring national income? Which methods have been followed in India? Answer: National Income is the money value of all goods and services produced in a country during a year. National income shows the economic position of a nation. The basic objective of an economy is to achieve economic progress. This is achieved by coordinating natural resources, human resources, capital, technology etc. National income will help to assess and compare the progress achieved by a country over a period of time. We can calculate national income by following any one of these methods. Considering the nature and requirements of the economy one or more methods are used for calculating national income. The three methods used for calculating national income are: A Production method B Income method C Expenditure method A. Production method This method is based on the total production of a country during a year. First of all production units are classified into primary, secondary and tertiary sectors. Then we identify the various units that come under these sectors. We estimate the goods and services produced in each of these sectors. The sum total of products produced in these three sectors is the total output of the nation. The next step is to find out the value of these products in terms of money. The money sent by Indian citizens working abroad is also added to this. Now we get the gross national income. GNI = Money value of total goods and services + Income from abroad. This method helps us to find out contributions of various sectors to national income. B. Income Method Factors of production together produce output and income. The income received by the factors of production during a year can be obtained by adding rent to land, wages to labour, interest to capital and profit to organisations. This will be equal to the income of the nation. In other words, total income is equal to the reward given to various factors of
  • 9. Unauthorized copying, selling and redistribution of the content are prohibited. This material is provided for reference onl Page 9 production. By adding the money sent by the Indian citizens from abroad to the income of the various factors of production, we get the gross national income. GNI = Rent + Wage + Interest + Profit + Income from abroad. This method will help us to know the contributions made by different agents like Landlords, labourers, capitalists and organizers to national income. C. Expenditure Method National income can also be calculated by adding up the expenditure incurred for goods and services. Government as well as private individuals spend money for consumption and production purposes. The sum total of expenditure incurred in a country during a year will be equal to national income. GNI = Individual Expenditure + Government Expenditure. This method will help us to identify the expenditure incurred by different agents. Any one of the above methods can be used for calculating national income. Production method = Income method = Expenditure method. Today national income in India is calculated and published by the Central Statistical Organization. All the three methods are used for calculating national income in India. Question 2: What do you understand by the investment multiplier? In what way does it defend the policy of public works on the part of the state during business depression? Answer: Investment multiplier is simply the multiplier effect of an injection of investment into an economy. In general, a multiplier shows how a sum injected into an economy travels and generates more output. For example if you buy $100 worth of chips. Say the stall owner saves $10 and spends $90 on burgers. Then the burger stall owner saves 10% that is $9 and consumes the rest ($81) on cheese, and so on... Each $ received 10% is saved (marginal propensity to save- MPS) and 90% consumed (marginal propensity to consume - MPC). This eventually results in 100/(1-.9)=$1000 worth of expenditure in the economy. The multiplier=1/(1-MPC).
  • 10. Unauthorized copying, selling and redistribution of the content are prohibited. This material is provided for reference onl Page 10 The investment multiplier is simply the same idea applied to an increase in investment as opposed to consumption above. Using consumption just makes it easier to understand; investment multiplier is just the same. Question 3: Discuss the various phases of business cycle: (i) Are cyclical fluctuations necessary for economic growth? (ii) Suggest appropriate fiscal and monetary policies for depression. Answer 3i: The business cycle or economic cycle refers to the ups and downs seen somewhat simultaneously in most parts of an economy. The cycle involves shifts over time between periods of relatively rapid growth of output (recovery and prosperity), alternating with periods of relative stagnation or decline (contraction or recession). These fluctuations are often measured using the real gross domestic product. To call those alternances cycles is rather misleading, as they don't tend to repeat at fairly regular time intervals. Most observers find that their lengths (from peak to peak, or from trough to trough) vary, so that cycles are not mechanical in their regularity. Business cycles are a type of fluctuation found in the aggregate economic activity of nations that organize their work mainly in business enterprises: a cycle consists of expansions occurring at about the same time in many economic activities, followed by similarly general recessions, contractions and revivals which merge in the expansion phase of the next cycle; this sequence of changes is recurrent but not periodic; in duration business cycles vary from more than one year to ten or twelve years; they are not divisible into shorter cycles of similar character with amplitudes approximately their own. (Burns and Mitchell) Actually there are six phases of business cycles counting the peak points (when booms turns into burst and the troughs).Business cycles are the recurring rises and falls in overall economic activity as reflected in production, employment, profits, prices, wages, and other macroeconomic series. Business cycles are recurring, but non-periodic, and one cycle must be more than a year, otherwise, it would be considered a seasonal cycle. Business cycles reflect the inability of the marketplace to accommodate smoothly such factors as new technologies, changing needs for occupational skills, shifting markets for new and substitute products, and risks in business investments. Business cycles can also reflect shortages and high prices

This material is provided for reference onl Page 11 created by external shocks such as war, cutbacks in oil production by the Organization of Petroleum Exporting Countries (OPEC), bad harvests, and natural disasters. Six phases of the business cycle are illustrated: Peak, Recession, Contraction, Trough, Recovery, and Expansion. One complete cycle can be measured from Peak-to-Peak or Trough-to-Trough. Beginning with the peak, the six phases of the business cycle unfold as follows. The Peak is the high point of continuous expansion just before the downturn in economic activity. This is followed by a Recession, the immediate downturn in economic activity after the peak in the business cycle, and represents the downward region of the cycle from the peak to the trough. If overall activity falls below the lowest level (i.e., trough) of the previous recession (lower horizontal dotted line on the graph), then this more severe decline may be referred to as Contraction. The Trough is the lowest point of the recession phase of the business cycle just before economic activity turns upward. Once economic activity turns upward, the economy is then in Recovery. This phase of the business cycle immediately follows the trough, and is characterized by the continuous expansion of economic activity. The economy is in Expansion when overall activity in the recovery phase exceeds the peak of the previous business cycle (upper horizontal dotted line). Sometimes during the upward phase of the business cycle, the expanding economy may not be increasing production fast enough to absorb those entering the labor market, and may even result in some of those already employed being laid off. That is, overall production and unemployment rates are both rising. This situation is known as a growth recession. If the opposite occurs, that is, if the economy expands beyond the long- run sustainable growth rate for a significant period of time, then this period may be characterized as a boom. Booms are usually followed by a recession. There may be obvious signs that the economy is in a recession, such as slack business activity and a rising unemployment rate. We may be affected personally, by having our workweeks reduced or even by losing our jobs. But there is also a set of observable measurements of a recession. These measurements provide the criteria for clearly defining dates for the peak and the trough.

This material is provided for reference onl Page 12 (ii) Fiscal policy focuses on controlling the government spending in order to accelerate or retard economic growth. During depression, an expansionary fiscal policy should be used which aims at increasing government spending to directly increase investment, employment and thus domestic demand. Expansionary fiscal policy is either financed through borrowing or tax increase. Monetary policy aims at controlling the liquidity in the market to spur up or slow down the economy. It is implemented primarily through interest rate control (though there are other ways as well). Usually the central bank is responsible for fixing the interest rate. During depression, an expansionary monetary policy is implemented (easy money) which aims to bring down interest rate or make money cheaper. It is then expected that with cheaper money, the private sector will increase production, which will increase employment and then demand.

Electron Control, Inc., sells voltage regulators to other manufacturers, who then customize and distribute the products to quality assurance labs for their sensitive test equipment. The yearly volume of output is 15,000 units. The selling price and cost per unit are shown below: Selling price $200 Costs: Direct material $35 Direct labor 50 Variable overhead 25 Variable selling expenses 25 Fixed selling expenses 15 150 Unit profit before tax $ 50 Management is evaluating the alternative of performing the necessary customizing to allow Electron Control to sell its output directly to Q/A labs for $275 per unit. Although no added investment is required in productive facilities, additional processing costs are estimated as: Direct labor $25 per unit Variable overhead $15 per unit Variable selling expenses $10 per unit Fixed selling expenses $100,000 per year Question: Calculate the incremental profit Electron Control would earn by customizing its instruments and marketing directly to end users. Answer: Ans: No of units produced annually =15000 Profit on selling price of 200 is 50 per unit. So total profit earned is 15000x50= 7, 50,000 If they sell it @ 275 to Q/A labs then: Added variable Expense=50 per unit
