Title: Maximizing the Value of the Firm


1
Maximizing 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.....

2
Steps 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.

3
Functional 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.

4
Functional 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.

5
Functional 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?

6
Total, 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

7
Examples 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.

8
Graphing 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.

9
Review 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

10
Review 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.

11
Review 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

12
Review 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

13
Review 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.

14
Review 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?

15
Review 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.
