Managerial Economics
Integrates and applies microeconomic
theory and methods to decision making
problems faced by private, public, and
not-for-profit organizations.
Managerial economics deals with
microeconomic reasoning on real world
problems such as pricing decisions
selecting the best strategy in different
competitive environments.
Slide 3
MAJOR TOPICS
• Demand and Supply Analysis
and how to estimate price elasticities with regressions
• Production and Cost Analysis
and how managers can estimate these relationships
• Monopoly, Competition, and Oligopolies
and how to make good pricing decisions in the real world
• Organization Architecture
and the economic problem of motivating agents
• Risk in Economic Decisions
and ways to modify or compare risks

Slide 5
Theories of Why Profit Varies
Across Industries
1. RISK-BEARING THEORY
2. DYNAMIC EQUILIBRIUM (or
FRICTIONAL) THEORY OF PROFIT
3. MONOPOLY THEORY OF PROFIT
4. INNOVATION THEORY OF PROFIT
5. MANAGERIAL EFFICIENCY
THEORY OF PROFIT
Slide 6
Objectives of the Firm
• Profit maximization
• Shareholder wealth = value of each share (V0)
times the number of shares outstanding, or
V0 · (shares outstanding). This is the present
value of expected future profits or cash
flows, discounted at the shareholders required
rate of return, ke, ignoring taxes.

V0 (shares outstanding) =   t /(1+ke) t
t=1
Slide 7
Firm Value
(Figure 1.2)
t = REVENUE – COST = TRt – TCt = PtQt – VtQt - Ft
• Value of the Firm = the present value of discounted cash
flows
N
(t ) / (1+ke)t =
t=1
N
(PtQt – VtQt – Ft) / (1+ke)t
t =1
• Whatever lowers the perceived risk of the firm (ke) will
also raise firm value.
• Whatever raises the price of the product (Pt) or the quantity
sold (Qt ) will raise firm value.
• Whatever raises variable cost (Vt )or fixed cost ( Ft ) will
reduce firm value.
Slide 8
• To make good economic decisions,
managers need to be able to forecast &
estimate relationships
• Will be forecasting demand (both Pt & Qt)
» applies to for-profit corporations
» non-profit organizations
• Hospital Administrators -- # patients
• University Administrator -- enrollment
• Regression analysis, time series
methods, and qualitative forecasting
methods used for forecasting
Slide 9
The Role of Profits
• Economic Cost (or opportunity cost) is
the highest valued benefit that must be
sacrificed as a result of choosing an
alternative.
• Economic Profit is the difference
between revenues and total economic
cost (including the economic or
opportunity cost of owner supplied
resources such as time and capital.

Slide 11
Agency Problems
• Modern corporations allow managers to have
no, or limited, ownership participation in the
profitability of the firm.
• Shareholders may want profits, but managers
may wish to relax.
• The shareholders are principals, whereas the
managers are agents.
» Conflicting motivations between these
groups are called agency problems.
Slide 12
• The Principal-Agent Problem
» Shareholders (principals) want profit
» Managers (agents) want leisure &
security
• Examples
» KKR’s takeover of RJR Nabisco to
refocus on wealth-maximization
» The LBO by O.M. Scott (a lawn fertilizer
company) from ITT improved Scott’s
performance
Slide 13
Solutions to Agency Problems
• Compensation as incentive
• Extending to all workers stock options,
bonuses, and grants of stock
» It helps to make workers act more like
owners of firm
• Incentives to help the company, because
that improves the value of stock options
and bonuses.
Slide 14
What Went Right?
What Went Wrong?
• Saturn Corporation
» Different kind of
car company in 1991
» No-haggle pricing
» Sales were above expectations
• But, margin of only $400 per car to GM
» GM earned only 3% on capital
» Saturn customers wanted bigger Saturns rather than
trade up to Buick, as GM hoped.
» When the dollar appreciated, Japanese firms could
price their cars more competitively.
Slide 15
Shareholder Wealth Maximization:
Necessary Conditions
• COMPLETE MARKETS - liquid markets
for firm's inputs and by-products (including polluting
by-products).
• NO SIGNIFICANT ASYMMETRIC
INFORMATION - buyers and sellers all know
the same things.
• KNOWN RECONTRACTING COSTS
future input costs are part of the present value of
expected cash flows.
Slide 16
Goals in the Public Sector and the
Not-For-Profit (NFP) Enterprise
 Public Goods are goods that can be consumed or used by
more than one person at the same time with no extra cost
(like a flood control or national defense).
 Sometimes governments produce public goods. Other times,
they are exclusive to one person (like a free meal).
 Instead of profit, NFP organizations may have as their goals:
1. Maximization of the quantity of output, subject to a
breakeven constraint.
2. Maximization of the utility (happiness) of NFP
administrators.
3. Maximization of cash flows.
4. Maximization of the utility of contributors to the NFP
organization.
Slide 17
• Which goal a NFP manager selects affects
decisions made.
» A food shelter manager may decide to maximize
the utility of contributors by selecting only
"healthy foods"
• Public sector managers are performance
monitored.
» V.A. hospital administrators are rewarded by reducing
the cost per bed over a year. Hence, they become
efficient with respect to costs.
» The "friendliness" of the hospital staff is harder to
measure, so friendliness will tend not be a high priority
of the public sector manager.
