- The document analyzes pricing strategies for Moser Baer Compact Discs using the Stackelberg game theory model of duopoly.
- It establishes the demand function for CDs based on sales data and defines key terms like supply chain, oligopoly, and duopoly.
- The problem is to find the optimal wholesale and retail prices using a Stackelberg model where either the manufacturer or retailer is the leader.
- Equations are developed for the manufacturer and retailer profits based on costs, revenues, and demand. The manufacturer stackelberg and retailer stackelberg models are defined and profit functions are derived.

Sales Forecasting for Management Consultants & Business AnalystsAsen Gyczew
ย
During many consulting projects, you may be asked to forecast the sales of the firm or check sales forecast models done by the customer. Sales forecasting requires a specific approach to data and also a lot of creative, out of box thinking, to address the issue of insufficient data and changing environment. In this presentation, I will teach you how to do fast and efficiently basic sales forecast models in Excel. We will create a relatively simple sales forecast. Nevertheless, they will significantly help your customer define strategy and decide whether he should open a new factory, enter a new field, buy a business. We will NOT get into complicated models, forecasts as in most case you will not have neither time nor data to do them. It would also require a wider knowledge of mathematics, statistics, econometrics and a usage of more advanced tools than Excel. The things you will learn in this presentation will be sufficient in 70% of the cases and can be done with the knowledge of basic Math. Such basic sales forecasts are especially important during Strategy projects, M&A projects and business development projects. In such projects, you want to get fast rough sales forecasts using simple methods. A similar approach as we will show in this presentation can be used as the starting point for budgeting models.
In the presentation you will learn the following things:
1. The essential concepts in sales forecasting and the main tools that you may need.
2. How to forecast sales in Excel using simple methods fast and efficiently
3. What drivers of sales you should take into account for selected industries. We will look at different cases studies to see how you can move from drivers to a working model in Excel

Memorandum Of Association Constitution of Company.pptseri bangash
ย
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

DEFINITIONS:
What is Supply Chain?
โA supply chain is the network of all the individuals, organizations, resources, activities and
technology involved in the creation and sale of a product, from the delivery of source
materials from the supplier to the manufacturer, through to its eventual delivery to the end
user. The supply chain segment involved with getting the finished product from the
manufacturer to the consumer is known as the distribution channel.
Supply chain management (SCM) is the oversight of materials, information, and finances as
they move in a process from supplier to manufacturer to wholesaler to retailer to consumer.
The three main flows of the supply chain are the product flow, the information flow and the
finances flow. SCM involves coordinating and integrating these flows both within and among
companies.โ
Supply Chain (n.d.)
What is the importance of price in oligopoly market?
โWe define oligopoly as the form of market organization in which there are few sellers of a
homogeneous or differentiated product. If the product is homogeneous, we have a pure
oligopoly. If the product is differentiated, we have a differentiated oligopoly. Oligopoly is the
most prevalent form of market organization in the manufacturing sector of most nations,
including India. Some oligopolistic industries in India automobiles, primary aluminium, steel,
electrical equipment, glass, breakfast cereals,cigarettes, and many others.
Since an oligopolist knows that its own actions will have a significant impact on the other
oligopolists in the industry, each oligopolist must consider the possible reaction of
7. Page | 6
competitors in deciding its pricing policies, the degree of product differentiation to introduce,
the level of advertising to be undertaken, the amount of service to provide, etc. Since
competitors can react in many different ways (depending on the nature of the industry, the
type of product, etc.) We do not have a single oligopoly model but many-each based on
the particular behavioural response of competitors to the actions of the first. Because of this
interdependence, managerial decision making is much more complex under oligopoly than
under other forms of market structure.โ
Pricing (n.d.)
What is duopoly?
โA duopoly is a form of oligopoly occurring when two companies (or countries) control all
or most of the market for a product or service.
There are two kinds of duopolies. In the first, the Cournot duopoly, competition between the
two companies is based on the quantity of products supplied. The duopoly members
essentially agree to split the market. The price each company receives for the product is based
on the quantity of items produced, and the two companies react to each other's production
changes until an equilibrium is achieved.
In a Bertrand duopoly, the two companies compete on price. Because
consumers will purchase the cheaper of two identical products, this leads to a zero-profit
price as the two competitors attempt to attract more customers (and thus more profit) through
price cuts. The threat of price undercutting means that Bertrand equilibrium prices and profits
are generally lower (and quantities higher) than in Cournot duopolies.โ
Duopoly (n.d.)

ANALYSIS:
Letโs take price of Moser Baer Compact Disks (CDs) ranging from Rs 20 to 44.
Letโs take a step of INR 2 i.e. an increase of INR 2 across different stores in the market.
Demand at Market:
Let the linear demand function be
q = a โ bp
where,
q = quantity sold
p = retail price
9. Page | 8
a = market potential
b = price elasticity
Estimation of Demand:
To establish the demand function we will do the following calculations:
โ ๐ = ๐๐ โ ๐ โ ๐
And
โ ๐๐ = ๐ โ ๐ โ ๐ โ ๐2
Let us now prepare a table consisting of retail price(p), quantity sold(q), Total

Therefore,
โ ๐ = ๐๐ โ ๐ โ ๐

and
โ ๐๐ = ๐ โ ๐ โ ๐ โ ๐2
15,912 = 416 a โ 14,040 b ---------(2)
From equation 1 & 2 we can get the value of a & b,
And those will be a=72 and b=1.
Hence the demand function is
q = 72 โ p (i)
Verification of Demand:
Let us plot the straight line graph of Price V/s Quantity.
FIG 1.2
We know that the equation of the straight line is
y = mx + c
From the graph, we get
y = -x + 72
Therefore,
m = -1, intercept
and c = 72, constant
y = -x + 72

THE PROBLEM:
We will consider a simple duopoly market where there is only one manufacturer and one
retailer.
The problem is to find the optimal wholesale price and retail price. We will be using
Stackelberg Game Theory to decide the optimum wholesale and retail price.
STACKELBERG GAME:
โThe Stackelberg leadership model is a strategic game in economics in which the leader firm
moves first and then the follower firms move sequentially. It is named after the German
economist Heinrich Freiherr von Stackelberg who published Market Structure and
Equilibrium (Masrktform und Gleichgewicht) in 1934 which described the model.โ
In game theory terms, the players of this game are a leader and a follower and they compete
on quantity and price. The Stackelberg leader is sometimes referred to as the Market Leader.
Firms may engage in Stackelberg competition if one has some sort of advantage enabling it to
move first. More generally, the leader must have commitment power. Moving observably
first is the most obvious means of commitment: once the leader has made its move, it cannot
undo it - it is committed to that action. Moving first may be possible if the leader was the
incumbent monopoly of the industry and the follower is a new entrant. Holding excess
capacity is another means of commitment.
The game is played in a sequential manner. Specifically, the manufacturer is the leader in the
game, which means it initiates the game by making the first move (e.g., order quantity to
12. Page | 11
suppliers), while the suppliers are the followers. The manufacturer knows that the suppliers
will decide by reacting to its decisions, so it takes this into account while making its own
decisions. Consequently, the game is modelled as a single leader โ multiple follower
Stackelberg game. As in any variant of game theory and its applications, the central
assumption is that players are rational and claimed that this assumption is often a common
knowledge. In the proposed game, the manufacturer, being the leader of this non-cooperative
Stackelberg game, is assumed to be rational in nature and his/her objective in a non-
cooperative Stackelberg game is to discover the best strategy in order maximize its profit
given all the possible move of its followers. Rationality is also expected from the suppliers as
long as they never choose dominated strategies. Thus, as long as the manufacturer and the
suppliers satisfy the rationality principle and are willing to remain in the game, the proposed
game is applicable; that is, they can determine their strategies that maximize their profit
functions. Otherwise, optimal decisions may not be guaranteed when the manufacturer or
suppliers or both leave the game.
Key Points:
STACKELBERG GAME:
โข The decision-making is sequential.
โข Either the manufacturer or the retailer acts as the market leader and first decides on
the wholesale price (w) or the retail price (p)
โข Then the other acts as the follower and then decides on p or w accordingly
โข If the manufacturer acts as the leader the game is called Manufacturer-Stackelberg
(MS) game
โข Else if the retailer acts as the leader the game is called Retailer-Stackelberg (RS) game
The assumptions we will use to solve the problem:
โข No stock-out or inventory at the retailerโs end
โข The retailer anticipates the demand q and orders exactly q quantity and sells exactly q
quantity
โข No stock-out or inventory at the manufacturerโs end
โข The manufacturer produces exactly q quantity and sells exactly q quantities to the
retailer
โข The manufacturer possess enough capacity to fulfil the order

What is Manufacturer Stackelberg Model?
The game is played in a sequential manner. Specifically, the manufacturer is the
leader in the game, which means it initiates the game by making the first move (i.e.
order quantity to suppliers), while the suppliers are the followers. The manufacturer
knows that the suppliers will make their decisions by reacting to its decisions, so it
takes this into account while making its own decisions. Accordingly, the game is
modelled as a single leader-multiple follower Stackelberg game.
What is Retailer Stackelberg Model?
In the context of a retailer Stackelberg supply chain, we examine how a direct channel
added by a manufacturer can influence the decisions of the retailer and the
manufacturer, and the impact it will have on their profits. We obtain equilibrium
prices for a retailer Stackelberg dual-channel supply chain. We find that, as compared
to a single retail channel supply chain, a dual-channel supply chain can enhance the
profits of the manufacturer and the supply chain. The retailer, however, will benefit
from the direct channel when the maximum sales in the retail channel are high. We
further propose a retailer's margin contract that can coordinate the dual-channel
supply chain and ensure that both the retailer and the manufacturer will be more
profitable.
The cost function for the manufacturer can be given as:
Cq = A +vq
Cq = (20 + 3q) (in thousand rupees)โฆโฆโฆโฆโฆ.. Cost of manufacturer
(ii)
where,
A = Total Fixed cost = 20, and
v = per unit variable cost = 3
Also Let,
14. Page | 13
w = wholesale price, and
p = Retail Price
๐๐ = Revenue of the retailer
๐ค๐ = Cost of the retailer
๐ค๐ = Revenue of the manufacturer
Manufacturerโs revenue/profit = ๐ซ ๐ด = ๐๐ โ ๐ช ๐ (iii)
Using equation (ii) in (iii), we get
๐ซ ๐ด = ๐๐ โ (๐๐ + ๐๐) = (๐ โ ๐)๐ โ ๐๐ (iv)
Using equation (i) in (iv), we get:
๐ซ ๐ด = (๐ โ ๐)(๐๐ โ ๐) โ ๐0 (v)
Also, Retailerโs Revenue/profit = ๐ซ ๐น = ๐๐ โ ๐๐ (vi)
Using equation (i) In equation (vi), we get:
๐ซ ๐น = (๐ โ ๐)๐ = (๐ โ ๐)(๐๐ โ ๐)
๐ซ ๐น = (๐ โ ๐)(๐๐ โ ๐)
(vii)
OPTIMIZATION MODELS:
MS GAME (Manufacturer Stackelberg):
Manufacturer is the market leader and retailer follows the manufacturer. The wholesale
price(w) is set by the manufacturer and based on that the retailer will set the retail price(p).
We will try to optimize the wholesale price(w) first and the retail price(p) based on the
optimized wholesale price.
Maximizing the manufacturers profit:
Using equation (v) to maximize, we get
๐ฆ๐๐ฑ
๐
โ = (๐ โ ๐)(๐๐ โ ๐) โ ๐๐
๐ด
Where for a given w, retailer will find optimal retail price at
๐ = ๐๐๐๐๐๐ โ (๐ โ ๐)(๐๐ โ ๐)
๐น
Hence to find the point of maxima, we find the partial derivative with respect to p, i.e.

Optimum wholesale price is achieved when,

๐คโ

๐คโ

๐คโ

Also optimum Retail price at ๐คโ

๐(๐) =
๐ฐ+๐๐

(From equation(viii))
๐โ

(37.5 + 72)

๐โ

Optimum Demanded quantity in our case is
๐โ
= 72 โ ๐โ
(From equation(viii))
๐โ
= 72 โ 54.75
๐โ
= ๐๐. ๐๐
Thus, the optimum profit of the manufacturer is
Max ๐ฑ ๐ = (๐ค โ 3)(72 โ ๐) โ 20 (from
equation (ix))
๐ฑ ๐
โ
= (37.5 โ 3)(72 โ 54.75) โ 20
๐ฑ ๐
โ
= (34.5 โ 17.25) โ 20
๐ฑ ๐
โ
= 575.125
And the maximum profit of the retailer is
๐ฑ ๐ = (๐ โ ๐ค)(72 โ ๐) (from equation
(vii))
๐ฑ ๐
โ
= (54.75 โ 37.5)(72 โ 54.75)
๐ฑ ๐
โ
= 17.25 โ 17.25
๐ฑ ๐
โ

RS GAME(Retailer Stackelberg):
The retailer is the market leader and sets the retail price first and the manufacturer is the
follower, follows the retail price to set the wholesale price. We will try to establish the MRP
in this model.

To maximize the manufacturerโs profit we find partial derivative with respect to w, i.e.

๐๐ค

Therefore, MRP =

๐๐ค

Result Validation:
The table shows the data for retail price, quantity demanded, manufacturerโs profit and
retailerโs profit for different wholesale price. (MS Game)

FIG 1.3
From the graph between the wholesale price and the manufacturerโs profit, it is clear that
the profit is optimum at a wholesale price of 37.5 and that is the price optimum price
established through MS game.
FIG 1.4
Also the graph between retail price and retailerโs profit for different wholesale price is
declining in nature. However as in MS game the manufacturer sets the optimum wholesale

Hence, we are able to set the wholesale price and the retail price through MS game as
manufacturer as the leader of the market and retailer as the follower such that both the
profits of the manufacturer and retailer are at optimum level.
