Week 1 slides Flashcards
What is the basic assumption of economic models?
The basic assumption of economic models is that people are motivated by financial incentives
What are the 2 basic assumptions of economic models?
- Greed: people prefer more over less - utility increases with each additional unit
- Risk-aversion: utility increases at decreasing rate with each additional unit
In what form can the 2 basic assumptions be seen? Also provide an example
A concave
Rather more than less, but decreasing increase.
Loss 2k to 1k is bigger than gain from 2k to 3k.
The utility gain is smaller.
What is another assumption of economic models?
Information asymmetry (private information)
The models are split by the actions/effort of what has been done and the characteristics of the information.
What are the 3 asymmetric information models?
Moral Hazard (!!)
Screening/adverse selection
Signaling
Describe the characteristics of moral hazard
- Agent has private information about their own actions
- Misalignment of interests between principal and agent (agent prefers leisure of effort)
- Principal elicits high effort and desired actions by offering contracts with performance bonus as reward for productive effort –> incentive compensation contracts.
Describe how the process relating to moral hazard works
Agent and principal have misaligned interests. Uninformed party (principal) moves first with incentive compensation contract. This gives principal a PM to judge agent –> problem limited since the agent is motivated.
What is moral hazard?
One party (agent) takes risks because the cost of consequences of those risks will not be fully borne by them, but by the principal.
What are the characteristics about screening?
Focus is on characteristics, not actions
- Agent has private information about characteristics
- Principal induces agent to reveal their private information about its type by offering contracts beneficial to high type, but not for low type.
How does screening effectively work?
The agent gives away a part of his private information by accepting such a contract. People with ‘undesired’ characteristics will be less likely to accept the contract.
What are examples of screening?
- Health insurer with higher premium and coverage so only certain people self-select into those plans
- Firm with strong incentive pay, only certain people self-select into those firms.
What are the characteristics of signalling?
Informed party moves first
- Agents communicate their type to principal by taking actions less costly to the high type.
- you communicate your characteristics with a strategy that low type can’t copy.
What are examples of signalling?
- Education (more costly for low type, so credible way to communicate ability for high type)
- Product warranty
What is the definition of signalling?
Agents take actions to credibly communicate their type to the principal.
What 2 things are many organizations characterized by?
- Asymmetric information (some members have informational advantage)
- Misaligned objectives (some people have different personal objectives than the corporate objective).
What caused the Wells Fargo problems?
Moral Hazard
Knowledge is valuable in decision making, so what must happen?
Bring (co-locate) decision rights and important knowledge for these decisions together.
What are the 2 alternatives to bring decisions rights and knowledge together (caused by dispersion of knowledge throughout organization)
- KTC: move knowledge to decision rights
- CC: move decision rights to those with knowledge
What 2 problems are created with the decentralization of decision rights?
Rights assignment problem: where to place decision rights?
Contro/agency problem: how to make sure decision rights are not used for personal gain but for corporate objectives.
What is the result of alienable rights not being applicable in firms?
No alienability of rights, so assign decision rights to lower-level employees with specific knowledge valuable for decision making.
Rely on internal delegation, offer rewards & punishments.
What is alienability?
The ability to sell or transfer ownership of assets or decision-making rights, and to pocket the proceeds from such transactions.
What is the agency problem?
Decentralized decision-makers might prioritize their own goals over the organization’s objectives.
What does completely centralized result in?
Low costs inconsistent objectives & high costs poor information
