Title: Lecture 11 Economic Theory of the Firm
1Lecture 11Economic Theory of the Firm
- There are two views of the firm
- 1. Neoclassical (traditional) theory
- Firm is a calculating entity, that makes
decisions, buys inputs, making output, and
selling for profit for loss - 2. Property rights theory
- Firm is a collection of contracts between owners
of resources, who wish to combine some portion of
their resources, for some period, for some purpose
2Traditional Theory of the Firm
- Traditionally, the firm headed by the
entrepreneur or manager makes decisions - What to produce?
- When and how to produce it?
- How much to produce?
- What is its price?
- The firm is seen as having a production function
- Relates inputs and outputs like a recipe
- q q (x,y,z)
- q is output
- x, y, z are inputs
- The exact form depends on technology, state of
knowledge, etc.
3A production function
- A production function is often a mechanical or
engineering view of productionlabor, supplies
and capital - 1 shovel of cement
- 3 shovels of sand
- 5 shovels of stone
- 4 liters of water
- Use labor to mix cement, sand, and stone for 1
minute - Add more water to get right texture
- Use labor and hoe to mix for 2 minutes
- Output 12 liters of wet concrete
- Most of this is engineering. The role of
economics is limited to the importance of price,
substitutes, etc. Important concepts, but not
difficult to grasp.
4Property Rights Theory Firms and Markets
- Where is the line between the market vs. command
and control (within the firm)? - The market relies on spot prices to provide
information and induce decisions - The firm relies on command and control within the
context of long term contracts to inform and
induce - The tradeoff
- Market is informationally efficient
- The firm is contractually efficient
- The balance between these two determines the
margin of choice between the firm and the market
5What Kind of Organizational Form to Choose?
- A key role of managers is to procure inputs in
the least cost mannerincluding providing
incentives for workers to be productive. - If this is not accomplished, costs will be higher
than needed and the firm will lose profits and
perhaps go out of business in a competitive
market. - Does a manager procure inputs from the market or
procure inputs within the firm?
6How to obtain needed inputs?
- Consider possible stages of production
- Obtaining raw materials
- Obtaining finished parts
- Assembly
- Transportation services
- Storage
- Wholesaling
- Retailing
7How to obtain needed inputs?
- Consider general services needed by an
organization - Accounting
- Finance (including credit service)
- Human Resources
- Legal Services
- Marketing (advertising, etc.)
- Janitorial Service
- Who is to provide such services?
8Who provides such needed services and functions?
- Should the firm produce within the organization
or outsource? - There is no one answermany conditions will
determine outcome. - Think of the great range of options
- Spot markets ? Long Term Contracts ?
- Vertical Integration (produce in house)
9Methods of Obtaining Inputs
- 1. Spot market or spot exchange
- Buyers and sellers of inputs exchange, but might
not deal again. Benefit deal with specialized
sellers, usually with low transaction costs. It
means we do not have to integrate the seller into
the firm or deal with over time. Possible
problem exploitation by seller who knows we are
ignorant or need supply badly.
10Methods of Obtaining Inputs
- 2. Contracts
- Legally based extended relationship between
buyer and seller. - Benefits specialization, ability to terminate
sellers who do not perform, reduction in
opportunistic behavior compared to spot markets.
Problems costly in complex environments
incentives to cheat act badly.
11Many Forms of Contracts
- Services (Deere and Ryder Trucks UPS and
Toshiba warranty laptop repairs UPS and Jockey
Japanese call centers in Dalien) - Joint Ventures (foreign firms in China)
- Leases (office buildings)
- Franchises (McDonalds, car dealers)
- Strategic Alliances (Merck Astra)
12Methods of Obtaining Inputs
- 3. Vertical Integration
- (Non-market exchange)
- When a firm chooses to produce an input
internally rather than contract with outsiders.
Benefits reduced opportunistic behavior by
outsiders and fewer contracting costs. Problems
lost specialization and increased organizational
costs.
13When Is Vertical Integration Most Likely to Be
Necessary?
- Brand name (goodwill) protection
- When there are specific assets
- When there are high sunk costs
- When contracts especially difficult to enforce
14Methods of Obtaining Inputs
- Summary
- Is there substantial specialized investments
relative to contracting costs? If nolikely to
use spot market. - If yesis the cost of contracting high relative
to the cost of integration? If yesvertical
integration if nocontracts with outside
suppliers.
15Recent Example Ford
- Ford had used annual bidding competition to
achieve low cost suppliers for auto parts (70
billion a year). - Problems high administrative cost, bankruptcy by
suppliers, quality control uneven - Solution longer term contracts with fewer
suppliers (down from 2,500 to 1,000) closer
working relationship estimated savings of 10
per year.
16Agency Costs
- Who gets what or thinks they deserve something
is a part of what we call Agency Costs or
Agency Problems. - Agency costs exist as a problem whenever a
principal hires an agent to act on his behalf. - Solving this universal problems is a key
managerial problem in managing personnel and in
controlling costs.
17A Major Drawback of Firms Agency Costs
- The agency problem arises from the separation of
ownership and control. - Owners of firms are interested in profit
maximization. - Managers and other employees are interested in
maximizing own self-interests. - How do we give managers an incentive to act as if
they were owners of the firm? How do we get
employees to not shirkthat is, work as hard as
they can in the manner the owners would want?
Telling people to work hard does not help muchit
is a matter of incentives.
18Agency Costs . . .
- These are a problem because we are human. If we
cheat ourselves, then no one else bears the
cost. So we never cheat ourselves. So the
one-person firm is efficient and does not suffer
agency costs. - It is natural for us to want to exploit others
get others to pay more than they agreed to pay or
we produce less than we agreed to produce. That
is, a divergence in interest between principal
and agent in a multi-person organization and in
contracts.
19Monitoring, Signals and Contracts
- Assume a company will need an average of 50 hours
of legal work a year at 100/hour. - The law firm has an incentive to inflate the
number of hours to maybe 70 hours. - Company knows that, so pays an expert to monitor
the law firm - Law firm knows it is being monitored so has
incentive to monitor itself. - How to avoid this problem both parties recognize?
- Parties may reach fixed price contract to avoid
monitoring costs send right signal.
20Monitoring
- We have incentives to shirk take more than we
should or work less than we should. Monitoring is
costly, so sensible to accept some losses. Many
forms of monitoring (spot checks, etc.). - Usually there is unequal (asymmetric) information
between parties. One knows more than the other
and can exploit that. - Examples. Person selling used car.
- Buy insurance (buyer exploits seller)
21Monitoring Bonding
- How do we assure customers that we will not
exploit them unfairlythat they will pay a
reasonable, market price? - Various devices
- Fixed price contracts Bonds Warranties
- Future price guarantees.
- Less formal Reputation. The evidence is strong
this matters greatly in the market. We pay
premiums to deal with firms with good reputations.
22Entrepreneurs and their Firms
- Key Managerial Problem
- Giving employees incentives to act as if they are
owners. - In general The entrepreneur or top manager must
cede authority to others. The movement has been
in this direction especially in knowledge-based
production.
23Decentralization Pros Cons
- Empowering workers and managers is a good
concept-- - BENEFITS
- 1. More effective use of local knowledge
- those closest know the most
- 2. Conservation of senior management top
people cannot know or do everything - 3. Training motivation for local managers
helps attract and keep good managers and train
future top managers
24Decentralization . . .
- A good idea but obviously not perfect--
- There Are Costs
- 1. Agency costs
- shirking self-dealing so control and
monitoring measures needed - 2. Coordination costs and failures
- duplication pricing errors
- 3. Less effective use of central information
- local managers cannot know all information the
central managers, so have inferior knowledge
25Decentralizing Team Decisions
- Create teams composed of people with different
expertise to make decisions - Ex.Hallmark Cards has teams of art, design,
production and marketing assigned by holiday with
decision rights rather than move produce from
functional area to areacut time in half. - BenefitsImproved use of specific knowledge and
employee buy in due to better information, more
cooperation less blame. - CostsCollective-action and free-rider problems.
- Same thing in car productionteam development
tried at Chrysler separate functional areas at
GM. Tradeoffs.
26Decision Management Control
- 1. Initiationproposals to use firm resources and
the structuring of contracts - 2. Ratificationchoice of initiatives to be
implemented - 3. Implementationexecution of ratified decisions
- 4. Monitoringmeasurement of performance of
decision agents and implementing rewards - Remember agents (managers within a firm) do not
bear the full cost of their actions, so cannot be
delegated both decision management and control
hierarchy still necessary. Make authority and
lines of control clear to avoid confusion.
27Questions How Do We Overcome Agency Costs?
- The larger the organization, or the greater the
distance from the owners to the workers, the more
likely that agency costs will become significant
large corporation look more like an inefficient
government agency. What economic incentives do
firms take to try to give workers proper
incentives?
28Question Large Organization with Simple
Monitoring
- Mary Kay Cosmetics grew from sale of 200,000 in
1963 to over 600 million in 1993, 30 years
later. The product is common and very
competitive. The key to growth was measurement of
employee effort and rewards. What was it?
29Question on Team Incentives
- Suppose different numbers of people are assigned
to pull a rope as hard as you can. - One person pulls the rope.
- Three people pull the rope together.
- Eight people pull the rope together.
- How does the pulling force (work effort) per
person change across these three cases?
30Incentives of Managers
- In the fast-food industry, about 30 of stores
are company owned and run by a salaried manager.
About 70 of the stores are run as franchises by
owner-operators who split profits with the parent
company. 1) Which kind of store would you think
would tend to be more profitable? - 2) Why then does the parent choose to own some?
Where would they be located? - 3) Would you expect employees to see a
difference in the managers?
