All sessions together Flashcards
TOF Approach
Identify the coordination and cooperation (incentives, motivation) problems in each alternative.
Use this to reason about what is the best alternative.
“Best” = alternative that creates most value for the involved parties.
What are some coordination problems?
Team work more difficult to execute; challenges of sequencing work; greater need for formalization, advance planning; difficult to read facial, body language; harder to explain tasks to new hires; etc.
Division of labor between parties not clear, insufficient pre-planning, no procedures for reacting to disturbances, lack of communication, non-overlapping beliefs/culture, etc. → omitting important activities, incompatible activities, resource allocation, break-up …
What are some cooperation problems?
Shirking may become an issue b/c of greater difficulties of monitoring remote work (but remote could also make individual efforts more transparent). Less peer pressure.
Shirking, hold-up, undesired knowledge leaks, poaching of key employees, lack of trust, etc. → frictions, low investments, break-up …
What is a firm ?
“A firm is characterized by the employment contract, in which an employee accepts to take unspecified future orders (within limits) from an employer against payment – i.e., AUTHORITY.” Coase [emphasis added].
Why does the firm exist?
Discovering relevant prices (coordination).
Negotiating and concluding a separate contract for each exchange (cooperation).
Coordinating when tasks are uncertain.
The firm may avoid many of these costs.
(Firm) Optimum size (boundaries):
where the costs of organizing a transaction inside the firm = cost of organizing it using the price mechanism (market).
Q1: From the perspective of the TOF, managers

Definition of a strategy in Game Theory
A specification of an action/choice for
each possible history/contingency/
situation which might occur.
Definition of Nash equilibrium
A payoff maximising strategy for each player, given the choice of strategy of other players.
How to sustain cooperation
-Between firms?
-Inside firms?
Between firms
Contract law, legal system, mediators/arbitrators, reputations, repeated interaction … that enforce contracts.
Inside firms:
Between employees, employers: Employment law, mediators/arbitrators, unions/employers’ associations, reputation, culture, repeated interaction.
Between organizational units: Fiat/authority, culture, repeated interaction.
What is imperfect enforcement?
These mechanisms help, but don’t work perfectly.
Reputation mechanisms are not perfect (think TrustPilot or Tripadvisor).
The legal system may be imperfect (slow, over-burdened, etc.), based on unfamiliar legal doctrine, or even corrupt.
What exactly happened in the dispute? Court may be asymmetrically informed; make ”wrong” decision.
Costly to make use of enforcement mechanisms (think corporate lawyers).
Improving outcomes by changing
Players—e.g., get rid of bad suppliers.
Payoffs—e.g., incentivize players to not choose ”bad” strategies (e.g., pay your employees more than what the rivals pay).
Choices—e.g., job descriptions (e.g., multi-tasking may have advantages, but also drawbacks …).
Information—e.g., management information systems, financial control, activity-based costing, benchmarking …
Interaction—e.g., repeated interaction often better than one-shot interaction.
Bounded rationality
humans have inherent cognitive limitations
Heuristics help
intuition, heuristics, rule of thumbs, etc. are useful.
Biases
Decision-making errors.
Q1: Nash equilibrium requires that there are “many” players.
True
False

Q2: When asymmetric information is introduced into a game, this typically
1. Changes the strategy set.
2. Changes the outcomes of the game.
3. Both A) and B).
- Both A) and B).
Q3: Cognitive biases help us understand why CEOs
A. Make errors that are entirely specific to the firm.
B. Make systematic decision making errors.
C. Make random decision making errors.
B. Make systematic decision making errors.
Q4: In a game, the number of subgame perfect equilibria will always be higher than the number of Nash equilibria.
True
False
False
Q5: In classical decision theory, decision-makers have unstable, preferences, limited attentional and computational capacities, and their behaviors are driven by expectation of consequences.
True
False

Q6. Loss aversion means that
1. We pay more attention to non-recoverable costs (potential losses) when considering future actions.
2. We feel losses more acutely than gains of the same amount.

True
False
False
What is efficiency?
Efficiency as maximizing the sum of producers’ and consumers’ surpluses.
For instance, the monopoly quantity vs. market quantity. The competitive output maximizes welfare i.e., the sum of producers and consumers surplus—so producing Qpc is efficient.
When can efficiency be defined as value maximization?
When 1) the utility of players can be measured in money equivalents (as in a ”reservation price”),
and 2) utilities measured in this way can be summed over players (as in the ”consumers’ surplus”),
then 3) efficiency can be defined as value maximization.
When is doing X (investments, organizational structure, contracts, etc.) efficient?
If it contributes to maximizing the Σ money equivalents of utilities (”value max”).
Two situations where markets -> efficiency (i.e., no need for firms!) (“first-best” outcomes).
The Fundamental Welfare Theorem (textbook, chpt 3).
The Coase theorem (textbook, chpt 4).
What is the (1st) Welfare Theorem?
If
1. each firm maximizes its profits, knowing the prices and its own production technology;
2. each consumer maximizes utility, knowing the prices and his own preferences;
3. income and prices are such that demand equals supply for every good and service,
then the resulting allocation of goods and services is Pareto optimal.
Some limitations:
Large number of consumers and producers
Law of one price
Anonymity
Production function view of firm
Communication structure
Contracts (complete contingent)
Complete rationality
Decentralisation
Coordination
Complete set of markets
No externalities
All goods and services can be exchanged
… Etc.
The Coase Theorem: Externality
Externality: Result of an activity that causes benefits (costs) to others with no corresponding compensation provided to (or paid by) those who generate the externality.
Does the equilibrium change if property rights are involved?
No. Regardless of the allocation of property rights, the equilibrium is the same.
The Coase Theorem (transaction costs, wealth effects.. etc.)
If 1) transaction costs are zero, so that bargaining is costless, and 2) there are no wealth effects, then any allocation of property rights results in an efficient outcome.
(“if there are no transaction costs, no wealth effects, voluntary bargaining always lead to efficiency”)
“No wealth effects” means
choices can be expressed in money;
choices do not depend on wealth position;
there are no financial restrictions regarding establishing a deal.
Realistic assumption when the amount of money involved is small relative to the financial position of the decision maker.
Q1: The First Welfare Theorem says that any efficient allocation can be decentralized as a competitive equilibrium.
True
False
False
Q2: In the world described by the First Welfare Theorem, there are no cooperation problems but there may be coordination problems.
True
False
False
Q3: Cognitive biases may be a source of bargaining costs.
True
False.
True
Q4: The Coase Theorem assumes that
Transaction costs are zero
Transaction costs are zero and there are no wealth effects.
The sub-game perfect equilibrium will always be optimal.
Transaction costs are zero and there are no wealth effects.
Q5: The First Welfare Theorem and the Coase Theorem:
Describe realistic theoretical ideals.
Present imaginary worlds in which markets don’t exist.
Describe the conditions under which first best efficient outcomes can be reached.
Describe the conditions under which first best efficient outcomes can be reached.
Q6. A key implication of the Coase Theorem is that the more complete a contract, the further away we get from efficiency (all else equal):
True
False
False
Q7: The Coase Theorem implies that the closer we get to full information, the closer we get to efficiency (all else equal):
True
False

True
False
False
When does agency problems arise?
When you need to incentivize people who carry out a task for you, but you don’t know what they know and there is a latent conflict of interests.
Ingredients in the PA problem
- Surplus available / gains from trade, i.e. there are opportunities for value generating exchange.
- Conflict of interests (how much effort and risk -> agent)
- Asymmetric information (the agent has superior information compared to the principal)
In an agency relation, moral hazard results when:
1) The agent can engage in post-contractual behavior that affects the utility of both principal and agent (externality);
2) the principal can only observe an imperfect signal of the agent’s effort (usually the outcome – not the actual effort exerted!) (control problem); and
3) the action the agent will take spontaneously is not optimal (inefficiency).
How can moral hazard be reduced?
By incentivizing the agent
(Tradeoff between ”insuring” the agent and giving him incentives)
What does “insuring the agent mean?”
= removing risk from him = putting him on a flatter wage (less performance-dependent) (NB: Agent usually assumed to be «risk-averse»)
What does “giving the agent incentives” mean?
Making his pay more performance-dependent
Explain the trade-off between stronger and weaker incentives
«Tradeoff»:
Give the agent stronger incentives → he works harder but he faces more risk which he does not like (wants a risk-premium) (P is happier, A is less happy)
Give the agent weaker incentives → he works less hard but faces less risk (smaller risk-premium) (P is less happy, A is more happy)
Three strategies for handling the agency problem
Change the choice possibilities (i.e., job descriptions, tasks, what can be done with corporate resources) – “change the rules of the game”.
Engage in monitoring – “change the information in the game”.
Provide incentives – “change the payoffs in the game”.
Look more closely at incentive management and how it interacts with monitoring.
The agent’s wage (linear wage model)
W = W0 + B ( e + 0l )
The agent’s utility
U = U(W) – C(e)
The agent’s utility from remuneration U(W) is dependent on the (uncertain) result z (i.e., the agent’s wage is uncertain).
The agent’s certainty equivalent
CEA = “expected wage”– “risk premium for agent”–“cost”
The principal’s certainty equivalent
CEP = “exp. value” – “exp. wage for agent” – “risk premium”
What does the optimal contract between principal and agent do?
Maximizes the total value of the relationship
Incentive intensity:
the size of beta
Monitoring intensity:
the amount of resources needed to estimate e.
W = W_0 + beta ( e + x )
Examples for a high beta (incentive intensity?)
For
1. Fine when effort has a high incentive elasticity.
2. ”Self-selection”: Laggards, shirkers stay away!
3. Can foster upgrading of skills and knowledge.
Etc.
Examples against a high beta (incentive intensity?)
What is ”z”?
1. Heterogeneity in the measure.
2. Multi-tasking problem; e.g., reduction of helpfulness.
3. How to decide the ”normal” effort level (for which beta = 0)?

Types of Incentive Pay
Gainsharing / group incentives:
Pay tied to gains in measures of group “success” (productivity, costs, quality, etc.).
E.g., tip pooling (waiters/tresses), casino dealers.
Profit-sharing: Pay tied to profits of firm.
E.g., Handelsbanken.
Efficiency wages: Paying employees a “premium.”
Piece rates:
Pay tied to amount of output produced.
E.g., sales commissions; garment workers.
Piece rates:
- Mention employee preferences
- Mention Employer preferences
Employee pref:
If the expected level of pay constant, employees may prefer time-based over piece rate.
Piece rate is “riskier”
Production process is uncertain.
Piece rate will cause self-selection on
Productivity
Risk aversion
Employer pref:
Advantages:
Productivity is increased among a given work force.
Attract most productive workers.
Disadvantages:
Quantity vs. Quality
Willingness to help coworkers
Treatment of equipment
Cost of monitoring output
Sales: who made the sale?
Is there a single “output” that can be measured?
Why are CEOs paid so (increasingly) well?
Conspiracies between well-connected aspiring CEOs to not underbid each other.
Imitation: Very high exec pay is a managerial practice that gives you credibility as a firm.
Skimming: CEOs are better able to manipulate their pay (e.g., in many stock option program, base pay wasn’t adjusted (downward))
Much greater risk of being dismissed
Mechanisms that handle agency problem
Board of directors (evaluate managers against high performance standards)
Shareholder activism (proxy battles, right to sue for damages if directors or managers fail to meet their obligations,
External forces: Market for corporate control, auditors, banks and analysts, regulatory bodies, legislation (e.g., SOX), media and public activists, etc.

Q6. In Safelite Glass, the increase in β led to less employee sorting in and out of the firm.
True
False.
True
Q7: According to Jensen & Murphy, the link between CEO pay and shareholder wealth is weak because
CEOs are risk-averse.
The public dislikes high CEO pay..
Boards are very good at (input-)monitoring CEOs so they don’t need to tie pay and firm performance together.
The public dislikes high CEO pay..
Q8: In agency theory, the contracting problem is that the principal fails to anticipate certain contingencies:
True
False (the P anticipates all possible contingencies but does not what exactly the agent did and the realization of the random variable).
False (the P anticipates all possible contingencies but does not what exactly the agent did and the realization of the random variable).
Q9: Inefficiency in a PA relation arises because
The parties face asymmetric information.
Because of the agent’s risk aversion.
Because it is not possible at the same time to make the agent pick the efficient action and efficiently share risk between P and A.
