Information Assymmety
When one party has more /different information than the other
Adverse selection (hidden information)
When sellers have information that buyers dont or vice versa

Increasing observability: The seller can screen and select the buyer with the desired characteristics
Moral Hazard (Hidden action)

Signalling
Attempt at showing hidden information so that buyer can be sure of the quality
Mutual insurance companies

Game Theory
A formal way to analyze/conceptualize strategic interaction among a group of rational players who behave strategically
Three steps of Analysis
- Problem formula (question)
- Model building (who, what, payoffs etc)
- Decision (using game theory analysis)
Assumptions of Game theory
- Players aim to maximize profits
- Rationality (all players are perfect calculators) #
- Common rules
Coordination Game
Players must coordinate their decisions in order to reach the outcome that is best
2-Entry game
A number of players have to decide simultaneously if they want to enter a market
Prisoners Dilemma
Situation where if both settle, there is minimum payout but if one confesses and the other doesnt, one of them gets maximum profits while the other looses. If both confess both loose.
Dominant strategy
The best strategy whatever the other player does
Nash equilibrium
A set of strategies one for each player such that each players strategy is a best response to other strategies (no incentive to unilaterally change my strategy)

Which governance mechanisms can solve agency problems
Theory of principal and agent
How should the principal design the agents reward structure
Which contract will be the efficient/optimal under different levels of risk attitude outcome uncertainty, task measurability, information asymmetry
Outcome based incentives (Rent contrat)
