Part A
Elasticity of Sales
Population Elasticity of sales can be defined as the responsiveness to sales due to change in
population. In other words it means that due to increase or decrease in population to what
extent and how sales is affected (Love,2013, p.125).
Here
s= Elasticity of sales
S= Sales
P= Population
dS= change in sales
dP= change in population
As given:
s= 0.8
Therefore
0.8= (dS/ (140000-130000))(130000/S)
0.8= (dS/10000)(130000/S)
0.8= (dS / 1) (13/S)
0.8/13= (dS/S)
dS/S= 0.0615
Therefore estimated percentage change in sales would be,
0.615100=6.1538%.
Now if the population increases by 10000,
The sale is expected to rise by:
(6.1538/100)10000

615.384 units.
(b) Price elasticity of demand
Price elasticity of demand is the responsiveness of price change on quantity or it can be
written as change in quantity demanded due to 1 unit change in price.
Here in this case
P0– Initial Price
Pf– Final Price
P0=7.50
Pf = 8.50
p=0.85
p = (dq/q)/(dp/p)
p = dq/dpp/q
p = dq/(Pf –P0)(7.50/q)
p = dq/(8.50 –7.50)(7.50/q)
-0.85= dq/q7.50
dq/q=-(0.85/7.50)
dq/q= -0.113
According to the problem it seems that with one unit increase in price the demand is expected
to fall by 0.113 units.
In terms of percentage, with a percentage change in price,
The demand is expected to fall by 0.113100 = 11.3% of the initial demand
The rise or fall in revenue is dependent on the nature of the elasticity curve; if the curve is
elastic the revenue is expected to fall with an increase in price, and if the demand curve is in
elastic the total revenue is expected to increase with increase in price, because people have
little choice then to move over to other goods.

Here,
TR= Total Revenue
dTR= Change in Total revenue
The conditions are if p>1,then dTR<0,which means with an increase in price total revenue
decreases.
p=1then the demand is unit elastic, in this case dTR=0, that is no change in the revenue level
with change in price.
p<1 Total revenue rises dTR>0 with an increase in price.
In the given problem the elasticity is less than 1, which means the demand for the product is
inelastic and the people have little scope to move over for other products and hence the
consumers will have to accept the price and this will result in additional revenue.
If the p =1.1,
Then in this case the price elasticity of demand is more elastic than before hence any kind of
increase in price will lead to a greater fall in demandin comparison to the previous case
dq/q=-(1.1/7.50)
=-0.1467
Therefore an increase in price while the price elasticity ofdemand is -1.1 will lead to a fall in
demand of the commodity by 0.1467 units which is greater than 0.113 units as calculated
earlier. As the elasticity -1.1 is close to being unit elastic dTR will be close to zero which
means that any increase or decrease in price will not affect the total revenue of the firm in a
massive way.
(c) Income Elasticity
Income elasticity is the responsiveness in quantity demanded due to change in income. If
income elasticity of a good is estimated to be 0.75 which means 1 unit increase in will
increase the demand of the good by 0.75 units (Saada,2013, p.115).
The conditions for income elasticity are:
Where

y- Elasticity of income
If y>0, the good is normal good
If ylies between 0 and 1 i.e. (0y1) then the good is considered as a necessary good.
Ify >1then the good is considered to be luxury good
Ify<0 the good is considered to be a inferior good.
From the above conditions it can be stated that the income elasticity of 0.75 means that the
good is a normal and necessary good, any kind of increase in price will lead to decrease in
demand and any income rise will lead to increase in demand for product either in absolute or
relative terms. As per the question the said firm depending on the income elasticity’s can
makes its pricing decision and classification of products on whether the good is a normal,
inferior, necessary or luxury good and take measures accordingly.
(d)Revenue and Cost
As per the given case scenario the following table consisting of Total Revenue, Marginal
Revenue, Total Cost, Marginal Cost, Average Cost, Total Profit, and Marginal profit has
been prepared.
Total Revenue: Total revenue in economics refers to the total sales of a firm based on a
given quantity of goods. It is the total income of a company (Shepherd, 2015, p.109). It is
derived by multiplying the price of the good and the quantity of goods sold. In this case the
given total revenue equation is
TR=$800Q - $0.2Q2
Basing on this equation and assuming quantities at an interval of 100 units the Total Revenue
column has been constructed.
Marginal Revenue:Marginal Revenue is the additional revenue that will be generated by
increasing product sales by one unit.
The Marginal Revenue equation for this firm stands to
MR=dTR/dQ =$800- 2(0.2) Q (2-1)
MR=$800-0.4Q

(In order to derive the marginal revenue functiona first order differentiation of the Total
Revenue function of the firm has been performed)
Total Cost: Is the summation of the variable cost and fixed cost which refers to the total
expense incurred in reaching a particular level of output. The total cost of the given firm is
TC=$38,000 + $250Q + $0.2Q2, where $ 38,000is the fixed cost and $250Q+$0.2Q2is
the variable cost.
Marginal Cost: is the additional cost incurred while producing one additional unit of output.
The marginal cost equation is determined through a first order differentiation of the total cost
function. Here the marginal cost function of the firm is
MC=dTC/dQ= $250+0.4Q (2-1).
MC= $250+0.4Q, and basing on this the marginal cost column has been prepared,
considering different values of output.
Average Cost: Is theper unit cost of a product which is derived simply by dividing the Total
Cost function by the total number of goods produced.
Average cost function for this case is:
AC=TC/Q = ($38000+ $250Q+ $0.2Q2)/Q
Total Profit: Total profit is the difference between the total revenue of the firm and the total
cost incurred by the firm in doing this.
Therefore,
Π = TR-TC
Π = (800Q-0.2Q2) - (38000+250Q+0.2Q2)
Π= 550Q-0.4Q2-38000
Here the total profit column has been created by using this function and applying various of
quantity at the specified interval level starting from 100 till 1000.
Marginal Profit:Marginal profit is the difference between the marginal revenue and the
marginal cost. Under the profit maximization approach, to maximize profits, a firm should
continue to produce a good or service up to the point where marginal profit is zero. Here the

Here the marginal profit equation has been prepared by taking first order derivative of the
profit function.
M(Π)= dΠ/dQ =d(550Q-0.4Q2-38000)/dQ
⇒M(Π)=550-2(0.4)Q(2-1)
M(Π)=550-2(0.4)Q
⇒M(Π)=550-0.8Q
In determining the profit maximising output we equate
M(Π)=0
550-0.8Q=0
⇒550=0.8Q
Therefore, Q*= 687 [Q* is the optimum output]

This shows that:
d2Π/dQ2 = d(550-0.8Q)/dQ2 =-0.8,
Therefore the output is the profit maximising output and has been portrayed in
the table in a similar way and the function is a profit maximisation function as
d2Π/dQ2<0 which is the necessary condition for fulfilling the objective of profit
maximisation. And 687 units appear to be the profit maximising output.
In order to determine the cost minimisation output we apply first order differentiation to the

And S.O.Ci.e. d2(AC)/dQ2>0 which is a necessary condition for minimisation, Therefore at
435.899 level of output the cost of the form is minimised, and negative output is not feasible
can be safely ignored.This has been depicted in the above graph at the point where the
average cost line intersects the marginal cost line.This is the point beyond which marginal
cost starts rising again and the point below which the minimum cost has not been reached
and there is further scope of output maximisation and can be explained form the above graph
(Baumol, 1977, p.158).
(F) Intuitive Analysis
The cost minimising output for the firm would be at the level where the average cost curve
intersects the marginal cost curve at the minimum point, analyticallywhich could be
translated as the point beyond the cost starts increasing.
The profit maximising output level is the level at which the profit is maximum foir the firm
beyond which the profit level start falling due to rising marginal cost and falling marginal
revenue of the firm.

a. Brief history of the international company Microsoft
Microsoft is a MNC (Multinational Company) based on computer technology (Şerban, 2014,
p.65). The history of establishment of Microsoft is related to the past when the bigwig
personalities Bill Gates and Paul Allen in Albuquerque founded the company in the 4th of
month of April in the year 1975.
Its founding members was responsible for the success of Microsoft in terms of the different
computer based products manufactured by it such as operating systems based software,
official documents based software like that of Microsoft Word and Microsoft Outlook and
different gaming and entertainment software like Xbox and popular search engines like Bing
(Norton & Baye, 2013, p.88).
In the year of 1980, Microsoft made a deal based on partnership based agreement with the
International computer manufacturing giant IBM(International Business Machines) in terms
of the condition that IBMwill get access to use of operating system produced by Microsoft

and other products in return of the favour that Microsoft will get the royalty for every
production related sales and marketing process of IBM. Microsoft Company was also
requested by IBMto write or create a new operating system for the variety of computers
based OS called OS/2 by IBMin terms of the deal (Sloman et al. 2013, p.33).
In this periodthe multinational company of Microsoft faced strict competition from the
substituteoperating systems of OS/2 operating in the market. The result of this competition
went in favour of Microsoft because of the personal operating system got the advantage of
the OS/2 based operating systems in terms technological advancement (Griffiths & Wall,
2011, p.55)
Microsoft flourished from the era when it started producing standardised quality of operating
systems such as that of Disk Operating System (DOS) whose manufacture brought the
company its real success. Till date, Microsoft is performing as the best leading company in
the business of computer operating systems and allied products though it faces a strict
competition from Google, a computer technology based contemporary company of similar
nature and potential as that of Microsoft.
b. Discussion of the nature of the market structure of Microsoft
Microsoft is a company which is based on monopolistic based market structure in terms of its
nature and scope of business conduction and performance. Its monopolistic based market
structure is the main reason for its success as a leader and pioneer manufacturing based
multinational company of international origin (Griffiths & Wall, 2011. p.23)
In order to discussing this regard we first need to understand the monopolistic market
structures and the essentials of the frame work. monopolistic is a market structure where the
businesses are price setters and strategy based decisions of producing and selling products
manufactured are taken by the monopolist in the market. The monopolistic market is based
on condition where there are many sellers and buyers in the market who use to differentiate
their products from each other. As Monopolies are price-setters, Monopolist sets its price
above the market clearing price. This gives us an indication of a very special feature of
monopolistic based market structure and it is that the goal or objective of monopolist or
monopolistic firm is profit maximisation which it does by setting price above the market
clearing price or price where the price where marginal revenue is not necessarily equivalent
11

to the marginal cost which necessarily happens in the case of market clearing equilibrium in
perfectly competitive equilibrium condition (Mahoney and Qian, 2013, p.1033). Thus the
monopolistic market has an imperfectly created market structure where price set by the
monopolist is equivalent to the marginal cost at the meeting point of marginal cost and
average revenue curve or demand curve. There is no supply curve in monopolistic as a single
set of prices or price is charged for any varied quantity of goods manufactured in the
monopolistic based market structure decided by the monopolist in terms of shift of average
and revenue curves rightwards when the quantity supplied is more at the similar price or
when the quantity supplied is less due to shift of the curves leftwards at the similar price.
There is hence no one to one correspondence or one to one relationship between prices sold
and quantity supplied in this variety of market framework. monopolistic market bas
suggested in the above mentioned illustrations belongs to market framework which is based
on the aim of maximisation of profits in terms of earning of supernormal profits that is profits
earned in excess of the normal or zero excess profits. The presence of excess capacities or
non-ideal capacities is the best outcome based on policy of profit maximisation strategy in
monopolistic market. Process based on phenomenon of excess capacity in imperfect
competition based market structure of monopolistic leads to improper allocation of total
amount of industrial resources and resource based capabilities allocated to the firm or
industry beforehand. Further there is no presence of freedom based on entry and exit of firms
to and fro from the industry as against the case of perfect competition. Therefore, there is no
challenge faced by the unit policy holding monopolist from outside entrants or external firms
surrounding its own industrial cum business environment so that its policy of excess profits
earning or supernormal profits earning will be hurt or hampered. An interesting case to be
noted here is that in monopolistic phenomenon may arise the need for welfare of the
economy for government regulation in terms of fixing the threshold level of maximum price
charged by the monopolist for its satiating the goal of profit maximisation. This is done
through different price regulation techniques which helps the government to put a barrier on
unnecessary rise of prices set by the monopolists for its products as this steps taken by the
monopolist may prove harmful or threatening to the interests of the of other industrial firms
surviving in the economy by huge struggle to compete against the unfair price competition
thrown by the monopolists. In terms of Pareto analysis, welfare generated in the monopolists
is always in terms of the costs being suffered by firms of other structural patterns and so
Pareto Welfare is not necessarily generated by the monopolistic firm to the society due to the
negative impacts of hiking of excess prices of products for fulfilment of selfish motives of
