3. Arms race Each side begins with 8. Costs 5 to arm. If one side arms and the other does not, it captures the 8 of the other side, and ends up with (8-3) + 8. If both arm, each ends up with 3 (=8-5). If neither side arms, each ends up with 8. The “payoffs” can be represented in a table as follows? The table lets you see what strategy would be best for each payer conditional upon the actions of the other… Thus: If Agent 2 arms, the best response of Agent 1 is to Arm If Agent 2 disarms, the best response of Agent 1 is to Arm If Agent 1 arms, the best response of Agent 2 is to Arm If Agent 1 disarms, the best response of Agent 2 is to Arm The expected outcome? Both sides arm even though both would be happier if Neither armed. This is an example of the Prisoners’ Dilemma.

4. Aside: The story behind the Prisoners’ Dilemma game. Two prisoners are arrested. For lack of evidence, the police can only put them away for 1 year each for some minor offence. If they had some evidence on a major offence then the police could put the prisoners away for an additional 10 years. So, the police make each prisoner the following offer: – if you squeel on the other prisoner and give us evidence leading to conviction of the other prisoner for the major offence, then we will forget the minor offence. So: If both Prisoners squeel then they each get put away for 10 years. If one only squeels, then the “squeeler” walks free while the “sucker” gets 11 years. If neither squeels then they get one year each. Will they squeel? Will the outcome depend on whether the players play at the same time of if one observes the actions of the other before playing?

5. Two more examples of the Prisoners’ Dilemma game: I.Aid and Adjustment: the role of Aid Conditionality. A similar game is played if countries do not like adjusting their policies and ceteris paribus, the World Bank does not like giving loans. It may be the case that both parties would be happier if there were loans and the country adjusts, but the logic of the game may result in no loans and no adjustment. Note that this outcome does not depend on who moves first – that is, it does not matter whether the World Bank has to give the loan before or after the country adjusts. What would provide a (happy) solution to the game is if one party is able to commit credibly to some conditional action. For example if the World Bank can commit to giving a loan conditional upon a country implementing adjustment, or, if the country could credibly commit to adjust given that the World Bank gives them a loan.

6. II Sharing an the costs of providing a public good: an irrigation project on neighboring farms. If nobody invests, they each earn 3. If anyone invests, the cost is 5, the return to each party is 4. Therefore, the private return is –1, the social return is 3. If both invest, the cost is 5, the return to each is 8. Note: This is also a Prisoners’ Dilemma game and the expected outcome is that neither party invests even though it would be better for all if all parties invest. If instead the return to each party when one party invests were 6, then this game would be strategically like a game of Chicken (like the car game). In a game of Chicken, even though it is in each person’s interest to invest (“swerve”) if the other does not, each would rather not invest and for the other player to invest instead.
