15.2 Transactions Costs
Transactions costs influence financial structure E.g., a $5,000 investment only allows you to purchase
100 shares @ $50 / share (equity) No diversification Bonds even worse—most have a $1,000 size
In sum, transactions costs can hinder flow of funds to people with productive investment opportunities
![Page 13: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/13.jpg)

15.3 Asymmetric Information: Adverse Selection and Moral Hazard In your introductory finance course, you
probably assumed a world of symmetric information—the case where all parties to a transaction or contract have the same information, be that little or a lot
In many situations, this is not the case. We refer to this as asymmetric (不对称 ) information.
![Page 15: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/15.jpg)

15.3.1 Asymmetric Information: Adverse Selection and Moral Hazard Asymmetric information can take on many
forms, and is quite complicated. However, to begin to understand the implications of asymmetric information, we will focus on two specific forms:
Adverse selection(不利选择 )
Moral hazard (道德风险 )
![Page 16: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/16.jpg)
16
15.3.2 Asymmetric Information: Adverse Selection and Moral Hazard Adverse Selection
1. Occurs when one party in a transaction has better information than the other party
2. Before transaction occurs
3. Potential borrowers most likely to produce adverse outcome are ones most likely to seek loan and be selected
![Page 17: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/17.jpg)
17
15.3.3 Asymmetric Information: Adverse Selection and Moral Hazard Moral Hazard
1. Occurs when one party has an incentive to behave differently once an agreement is made between parties
2. After transaction occurs
3. Hazard that borrower has incentives to engage in undesirable (immoral) activities making it more likely that won't pay loan back
![Page 18: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/18.jpg)

15.3.4 Asymmetric Information: Adverse Selection and Moral Hazard The analysis of how asymmetric information
problems affect behavior is known as agency theory.
We will now use these ideas of adverse selection and moral hazard to explain how they influence financial structure.

15.4 Lemons Problem
Lemons problem in used car market: potential buyers of used cars are frequently unable to assess the quality of the car, that is, they can tell whether a particular used car is a good car or a LEMON that will continually give them grief.
Adverse selection is referred to as the Lemons problem.
![Page 20: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/20.jpg)

15.4.1 The Lemons Problem: How Adverse Selection Influences Financial Structure
Lemons Problem in Securities Markets
1. If can't distinguish between good and bad securities, willing pay only average of good and bad securities’ value
2. Result: Good securities undervalued and firms won't issue them; bad securities overvalued so too many issued
![Page 21: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/21.jpg)

15.4.2 The Lemons Problem: How Adverse Selection Influences Financial Structure Lemons Problem in Securities Markets
3. Investors won't want buy bad securities, so market won't function well
Explains Fact # 1 and # 2 on p372 ( p378)
Also explains Fact # 6 on p374: Less asymmetric info for well known firms, so smaller lemons problem
![Page 22: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/22.jpg)

15.4.3 Tools to Help Solve Adverse Selection (Lemons) Problems1. Private Production and Sale of Information (e.g.,
Moody and S&P)
– Free-rider problem (“搭便车”问题 ) interferes with this solution
2. Government Regulation to Increase Information(explains Fact # 5 on p374)
– For example, annual audits of public corporations
– Does not eliminate the problem
![Page 23: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/23.jpg)

15.4.4 Tools to Help Solve Adverse Selection (Lemons) Problems3. Financial Intermediation
Analogy (类似 ) to solution to lemons problem provided by used car dealers (二手车商)

15.5 How Moral Hazard Affects the Choice Between Debt and Equity Contracts
Moral Hazard in Equity Contracts: the Principal-Agent Problem (委托 -代理问题 )
1. Result of separation of ownership by stockholders (principals) from control by managers (agents)
2. Managers act in own rather than stockholders' interest
![Page 25: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/25.jpg)
25
15.5.1 How Moral Hazard Affects the Choice Between Debt and Equity Contracts Tools to Help Solve the Principal-Agent Problem
1. Production of Information: Monitoring (costly state verification)
2. Government Regulation to Increase Information3. Financial Intermediation (e.g, venture capital)4. Debt Contracts (lenders only care if the loan can be
repaid)
Explains Fact # 1: Why debt is used more than equity
![Page 26: Chapter 15 Why Do Financial Institutions Exist?. 2 Chapter Preview This chapter provides an outline of this literature to the student and provides him](https://reader035.vdocument.in/reader035/viewer/2022062314/56649e105503460f94afc4c6/html5/thumbnails/26.jpg)
26
15.5.2 How Moral Hazard Influences Financial Structure in Debt Markets Because of the design of debt contacts, borrowers
only pay a fixed amount and keep any cash flow above this amount. In some circumstances, this creates an incentive for borrowers to take on riskier projects.
For example, if a firm owes $100 but only has $90, it will be bankrupt. The firm “has nothing to lose” by looking for “risky” projects to raise the needed cash.

15.5.3 How Moral Hazard Influences Financial Structure in Debt Markets Tools to Help Solve Moral Hazard in
Debt Contracts1. Net Worth
2. Monitoring and Enforcement of Restrictive Covenants (契约 )

Financial Crises and Aggregate Economic Activity
Our analysis of the affects of adverse selection and moral hazard can also assist us in understanding financial crises, major disruptions (破坏) in financial markets. Then end result of most financial crises in the inability of markets to channel funds from savers to productive investment opportunities.
