““The best things in life are The best things in life are free. . .”free. . .”
Free goods provide a special challenge for economic analysis.
When goods are available free of charge, the market forces that normally allocate resources in our economy are absent.

THE DIFFERENT KINDS OF THE DIFFERENT KINDS OF GOODSGOODS
When thinking about the various goods in the economy, it is useful to group them according to two characteristics:◦ Is the good excludable?◦ Is the good rival?

◦Excludability refers to the property of a good whereby a person can be prevented from using it.
Rivalry◦Rivalry refers to the property of a
good whereby one person’s use diminishes other people’s use.

PUBLIC GOODS: ProblemPUBLIC GOODS: ProblemA free-rider is a person who receives the
benefit of a good but avoids paying for it.
The free-rider problem prevents private markets from supplying public goods.
The Free-Rider Problem The Free-Rider Problem
Solving the Free-Rider Problem◦The government can decide to
provide the public good if the total benefits exceed the costs.
◦The government can make everyone better off by providing the public good and paying for it with tax revenue.
The Difficult Job of Cost-Benefit The Difficult Job of Cost-Benefit AnalysisAnalysisCost benefit analysis refers to a
study that compares the costs and benefits to society of providing a public good.
In order to decide whether to provide a public good or not, the total benefits of all those who use the good must be compared to the costs of providing and maintaining the public good.
COMMON RESOURCESCOMMON RESOURCESCommon resources,
like public goods, are not excludable. They are available free of charge to anyone who wishes to use them.
Common resources are rival goods because one person’s use of the common resource reduces other people’s use.
Tragedy of the CommonsTragedy of the Commons
The Tragedy of the Commons is a parable that illustrates why common resources get used more than is desirable from the standpoint of society as a whole.◦Common resources tend to be used
excessively when individuals are not charged for their usage.

CONCLUSION: THE IMPORTANCE OF CONCLUSION: THE IMPORTANCE OF PROPERTY RIGHTSPROPERTY RIGHTS
The market fails to allocate resources efficiently when property rights are not well-established (i.e. some item of value does not have an owner with the legal authority to control it).
When the absence of property rights causes a market failure, the government can potentially solve the problem.

Agency theoryAgency theoryTheory describing conflicting
relationship between principal and agents.◦Principal: employers◦Agent: employees◦Cause of conflict: difference of interests
(self interests) due to delegation of authority
◦Agency relationship: (1) between stockholders and managers and (2) between debtholders and stockholders.
◦As an impact Agency relationship moral hazard problem may arise.
Behavioral Theory-Cyert and Behavioral Theory-Cyert and March March Contrary to traditional
microeconomic theories-firms take multiple of objectives due to various internal conflicting factors.
Cyert and March:◦Various groups or coalitions exist
within the organization as that shares a consensus on the goals
◦Goals: production, stock, sales, market shares, profit and so on.

Price leadership modelPrice leadership modelAssumes that in some market, there is
one dominant firm in the industry that ◦Determine the level of demand and sets
the price ◦Other firms in the industry behave like
perfectly competitive price-taking firmsPossible due to large amount of
market sharePrice leader maintains the price such
that the level of demand remains unreduced

Economics with corporate Economics with corporate decision makings and public decision makings and public policy designpolicy design
Decision making in Corporations involves:◦ Demand analysis, production functions and
costs, pricing decisions and policies, entry and exit strategies and so on..
◦ Understanding of economics (managerial economics) provides strong foundations for such analyses
Public policy design requires understandings various conditions such as efficiency, effects of taxes, externalities, international trade, elasticity and so on.
