Conclusion
I. Introduction
Property right
Property right is generally effected through contracting individual behavior in organizations.
In this paper, we focus on the contract between the owner and the manager of the firm
Agency cost
Agency relationship is a contract under the principal engage the agent to perform service on their benefits which involves some decision making authority to the agent.
Agency costs include ,
The monitoring expenditures by the principal
The bonding expenditure by the agent
The residual loss
The definition of the firm
The private corporation or firm is simply one form of legal fiction which serves as a nexus for contracting relationships
legal fiction : certain organizations to be treated as individuals
II. Assumption
Permanent assumption
P.1 All taxes are zero
P.2 No trade credit is available
P.3
All outside equity shares are non-voting
P.4
No outside complex financial claims,such as convertible bonds or warrants can be issued
P.5 No outside owner gains utility other than through the wealth and the cash flow
P.6
All dynamic aspect of the multiperiod nature of the problem are ignored
P.7
The manager ’ s wage are held constant throughout the analysis
P.8
There exist a single manager with ownership interest in the firm
Temporary assumption
T.1
The size of the firm is fixed
T.2
No monitoring or bonding activities are possible
T.3
No debt financing through bond, preferred stock, or personal borrowing is possible
T.4
All element of the manager ’ s decision problem included by the presence of uncertainty and the existence of diversifiable risk are ignored

IV. Agency cost on debt
Three part of agency cost on debt
The incentive effects associated with highly leveraged firms
The monitoring and the bonding expenditures by the bondholders and the owner-manager
Bankruptcy and reorganization costs
The incentive effects
The opportunity wealth loss caused by the impact of the debt on the investment decision of the firm.
The incentive effects
Bankruptcy behavior is the willingness of the residual claimant to engage in extremely high risk projects when there is no equity at stake.
Under-investment is often find that new investment helps the bondholders at the stockholders ’ expense
The role of monitoring and bonding cost
To limit the managerial behavior which results in reductions in the value of the bonds for the bondholders

Risk and the demand for outside financing
The owner-manager will invest 100% of his personal wealth in the firm and then resort to outside financing but in fact he allocate his wealth in diversified ways to reduced the risk. So when he want to reduce this cost he will bear some agency cost( from the issuance of equity and debt)

VI. Qualifications and extensions of the analysis
Multiperiod and extension of the analysis
Throughout our analysis we are dealing only with a single investment-financing decision and have ignored the future financing-investment decisions . If we take this into account it will have some changes such as the future sales of outside equity and debt, manager ’ s decision, agency cost and etc.
The control problem and outside owner ’ s agency costs
We have assumed that all outside equity is nonvoting . If such equity have voting right, the manager will concern about the effects on his long-run welfare of losing effective control of the firm (the danger of being fired). So to determine an equilibrium distribution of outside equity is necessary.
A note on the existence of inside debt and some conjectures on the use of convertible financial instruments

Some other convertible securities such as warrants, convertible bonds, and convertible preferred stock
Monitoring and the social product of security analysts
A large body of evidence exist which indicates that security prices incorporate in an unbiased manner all public available information and much of what might be called “ private information.
”
Furthermore, the security analysis activities will reduce the agency costs associated with the separation of ownership and control they are indeed social productive.
Specification in the use of debt and equity
Our previous analysis of agency costs suggests at least one other testable hypothesis: I.e., that in those industries where the incentive effects of outside equity and debt are widely different . The theory predicts the opposite would be true where the incentive effects of debt are large relative to the incentive effects of equity.
