Title: Maximizing the Value of the Firm
1Maximizing the Value of the Firm
- The value of the firm is impacted by
- Total Revenue.... which is a function of team
quality, market size, stadium etc..... - Total Cost .... which is a function of the player
salaries, administrative expenses, stadium
expenses.....
2Steps in the Decision Process
- Economic relations must be expressed in a form
suitable for analysis the managerial decision
problem must be expressed in analytical terms. - Optimization techniques must be applied to
determine the best, or optimal, solution in light
of managerial objectives.
3Functional Relations EquationsDefinitions
- Equations Analytical representation of
functional relationships. - Dependent Variable The variable on the left
side of the equation...the y-variable...the
variable whose value is dependent upon changes in
the x-variables...the endogenous variable. - Independent Variable The variables on the right
side of the equation...the x-variables...the
variables who determine the value of the
y-variable...the exogenous variable.
4Functional Relations EquationsMore Definitions
- Endogenous variable A factor that is determined
by the independent variables in the model. - Exogenous variables A factor determined outside
the model, yet impacts the dependent variable in
the model.
5Functional Relations Equations
- TR f(wins)
- In words....
- Total Revenue is a function of wins.
- What is endogenous?
- What is exogenous?
- Are there other variables that will impact total
revenue?
6Total, Average, and Marginal RelationsDefinitions
- Marginal change in a dependent variable caused
by a one unit change in an independent variable. - A Marginal Change is represented as
- ?Y / ?X
- Alternative definitions
- Rate of change
- Slope
7Examples of Marginal Relationships
- Marginal Revenue change in total revenue
associated with a one-unit change in output. - Marginal Cost Change in total cost associated
with a one-unit change in output. - Marginal Profit Change in profit associated
with a one-unit change in output.
8Graphing Total, Marginal, and Average Relations
- Slope a measure of the steepness of a line.
- OR The rate of change
- The marginal relation
- Tangent a line that touches but does not
intersect a given curve. - This is used to find the slope of a nonlinear
curve.
9Review of Basic Microeconomics
- Law of Demand As the price of a good rises,
quantity demand will fall, ceteris paribus. - In equation form P a bQ
- Total Revenue Price Quantity
- In equation form TR PQ
- OR TR aQ bQ2
10Review of Basic Microeconomics
- Revenue Maximization Activity level that
generates the highest revenue. - If P 100 2Q, how much should I produce to
maximize total revenue? - Marginal Revenue 100 4Q
- Marginal Revenue is the slope of the total
revenue curve - Be able to find the slope of a curve.
- Total Revenue is maximized when marginal revenue
is zero. WHY??? - When Marginal Revenue is positive, Total Revenue
is rising. - When Marginal Revenue is negative, Total Revenue
is falling. - When Marginal Revenue is zero, Total Revenue is
neither rising or falling, therefore it is
maximized. - Therefore, total revenue is maximized at 25 units.
11Review of Basic Microeconomics
- Own-price elasticity
- ?Q / ?P
- How does elasticity vary along a linear demand
curve? - The upper half of a linear demand curve is
elastic. - The lower half of a linear demand curve is
inelastic. - BE ABLE TO EXPLAIN WHY!!!
- The search for substitutes as price increases
12Review of Basic Microeconomics
- Connecting Elasticity to Total Revenue
- If change in Q gt change in P
- decreasing the price will increase TR
- and marginal revenue must be positive.
- If change in Q lt change in P
- increasing the price will increase TR
- and marginal revenue must be negative.
- BE ABLE TO ILLUSTRATE THE RELATIONSHIP
13Review of Basic Microeconomics
- What is the objective of the firm?
- PROFIT MAXIMIZATION
- Profit Total Revenue Total Cost
- To understand profit, you need to understand both
revenue and cost. Understanding total revenue
begins with the Law of Demand. Understanding
total cost begins with the Law of Diminishing
Returns.
14Review of Basic Microeconomics
- The Law of Diminishing Returns As a variable
input increases, holding all else constant, the
amount of output from each additional input
employed will eventually decline. - The Law of Diminishing Returns is the foundation
from which we build the relationship between
output and marginal cost. - Because of the law of diminishing returns, in the
short-run marginal cost will rise for a firm as
output is increased. - Is this true in professional sports?
15Review of Basic Microeconomics
- Profit Total Revenue Total Cost
- Marginal Profit MR MC
- Profit is maximized when marginal profit equals
zero. WHY? - When marginal profit is positive (MRgtMC), profit
is rising. - When marginal profit is negative (MRltMC), profit
is falling. - When marginal profit is zero (MRMC), profit is
not rising or falling, it is maximized.
