Why Study Economic Principles ?•Modern business conditions are changing so fast and becoming so competitive and complex that personal business sense, intuition and experience alone are not sufficient to make appropriate business decisions. It is in this area of decision making that economic analysis contribute a great goal

Process of decision making i. Determining and Defining the Objective
ii. Collection and analysis of the information regarding the objective
iii. Inventing, developing and analyzing possible course of action
iv. Selecting the best available alternative

1. The Opportunity Cost•The cost involved in any decision consists
of the sacrifices of alternatives required by that decision.
•The opportunity cost of a choice is the value of the alternative forgone.
•Expresses basic relationship between ‘scarcity’ and ‘choice’

Parameters• Opportunity costs are not restricted to
monetary or financial costs
• Other aspects such as pleasure, time lost and output forgone are considered too
• For example, Appointing a new manager in the business
![Page 12: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/12.jpg)
Appointing a new ManagerOption A Option B• Promotion of an internal
employee to a managerial position with experience but without qualification
• the opportunity cost for promoting an internal employee to a managerial post is the lack of required qualification
• Appointing a new employee with the required qualification
• The opportunity cost for recruiting a new employee is the experience and commitment of the present internal employee towards the business
![Page 13: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/13.jpg)
2. Marginal Principle •Widely used term in Economics
•The term ‘Marginal’ refers to the change in total quantity or value due to one-unit change in its determinant
•This could be an increasing or a decreasing change
![Page 14: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/14.jpg)
Elements of Marginal Principle•Total Cost of Production (TCn)•Total Revenue (TRn)•Marginal Cost (MC)•Marginal Revenue (MR)•Total Cost for producing an additional
unit of the commodity (TCn-1)•Total Revenue by selling an additional
unit of the commodity (TRn-1)
![Page 15: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/15.jpg)
•Total Cost of Production (TCn) - The total cost of production of a
commodity depends on the number of units produced.
example, if 300 units are produced at Rs.20 each then the Total Cost amounts to Rs.6000
•Total Revenue (TRn) - The total revenue of the firm depends
on the total number of units it sells. example, 300 units sold at Rs.35 each
amounts to a Total Revenue of Rs.10,500
![Page 16: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/16.jpg)
•Marginal Cost (MC) - The marginal cost is the change in
the total cost as a result in producing an additional unit.
example, Total cost of producing 300 units is Rs.6000 and the total cost of producing an additional unit is 6020.
[ MC = TCn – TCn-1 ] MC = 6020 – 6000 MC = 20
![Page 17: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/17.jpg)
•Marginal Revenue - The Marginal revenue is the revenue
collected due to a sale of an additional unit.
Example, Total Revenue earned by selling 350 units is Rs.10,500 and the Total revenue earned by selling and additional unit is 10,535
[ MR = TRn – TRn-1 ] MR = 10535 – 10500 MR = 35
![Page 18: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/18.jpg)
Limitations1. It can only be applied where the management has the
Total Cost (TC) and Total Revenue (TR) data for each and every unit of output is recorded or where the management is fully aware of the cost of producing one additional unit and the price expected to be received from the sale of that unit.
Business that manufactures large units: i . Airplanes ii . Ships iii . Buildings iv . Turbines … etc.

2. The concept of ‘Marginal’ value, when used in cost analysis, reduces the value of MC to the change in variable cost only. Therefore, marginal analysis can only be applied to a situation in which only the variable cost changes
![Page 20: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/20.jpg)
3. Incremental Principle• Incremental principle is the opposite of marginal
principle
• Incremental principle is applied to business decision that involves bulk production and constant change in total cost and the total revenue
• Data is easily available
• Combination of fixed and variable cost
![Page 21: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/21.jpg)
Elements of Incremental Principle•Incremental Cost - The total change in cost is called the
incremental cost - Incremental cost can be defined as
the cost that arises due to a business decision
![Page 22: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/22.jpg)

Elements of Incremental Principle•Incremental Revenue
- When a business decision is successfully implemented, it results in a significant increase in the total revenue
- This increase in the revenue is termed as incremental revenue
![Page 26: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/26.jpg)

Incremental Reasoning
•Conclusions based on incremental concept (Incremental Cost + Incremental Revenue) in business decision is termed as Incremental reasoning
•Incremental Reasoning is used in accepting or rejecting a business proposition
![Page 30: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/30.jpg)

Close StudyMarginal Principle Incremental Principle• Marginal Value is
calculated for an additional unit produced
• Fixed cost must remain the same
• A theoretical concept and difficult to calculate in real life
• Incremental Value is calculated for bulk production and large total cost
• Fixed cost is tentative to change
• Used in Business decision more frequently and easy to calculate
![Page 33: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/33.jpg)
4. Contribution Analysis
•The analysis of a business decision between Incremental Revenue and Incremental Cost
•Generally applied to analyze the contribution made by overheads costs and revenue
![Page 34: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/34.jpg)
It is a useful technique for taking business decision on:
•Whether or not to accept a project ?•Whether or not to introduce a new
product ?•Whether or not to accept a new order ?•Whether or not to add an additional
plant ?•Whether to make or buy ?
![Page 35: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/35.jpg)
Costs taken into consideration for Contribution Analysis•Incremental Costs i. Present Explicit Costs a. Explicit variable costs . Direct labour cost . Direct material cost . Direct variable overheads b. Fixed Costs . New additional equipment . New additional personnel
![Page 36: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/36.jpg)
ii. Opportunity Cost iii. Future Incremental Costs . Depreciation . Reserves . Advertising

Incremental Revenues
i. Present Explicit Revenue
ii. Possible Opportunity Revenue
iii. Possible future revenue

5. The Equi-Marginal Principle•Allocation of available resources amongst
the alternative activities
•An input should be so allocated that the value added by the last unit is the same in all cases
•Goal of maximizing profits
![Page 40: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/40.jpg)
Consumer point of view•Every commodity will have different utility
for different consumer.
•The consumer will want to purchase both commodities and will want to reap highest possible marginal utility
•This is possible when the consumer complies his purchase of commodities in a way that gives maximum value
![Page 41: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/41.jpg)

Business point of view•When a business intends to start a new
project and get and faces problems of resource allocation between its alternatives
•Equi-Marginal principle helps in deciding how much resources to allocate in which project by studying the marginal utility of each project.

6. Time Perspective•All business decision are taken within a
certain time limit
•Time perspective i. Short run ii. Long run
• Determination of time perspective is of great significance specially where projects are involved
![Page 45: Fundamental economic concepts used in business decisions](https://reader036.vdocuments.mx/reader036/viewer/2022070518/58ec84b71a28abf06f8b47c5/html5/thumbnails/45.jpg)
•Short RunA decision to buy explosive materials for manufacturing crackers involves short run demand prospect
•Long RunSpending on labor welfare. i. Will result in expense initially ii. Will increase productivity in long run
