Bargaining in the Shadow of Power
Part I. The Puzzle of Dyadic
Interaction
A. Why do some pairs of states have dramatically different relationships?
Conflict
Hostile statements
Hostile nonviolent actions
Use, threat, display of force
War
Vs.
Positive statements
Diplomatic recognition
Intercultural exchanges
Alliances
Trade
Aid

US-Iraq 1987: US forgives Iraqi attack on
USS Stark , aids Iraq
US-Iran 1987: US destroys Iranian oil platforms, ships
Iran-Iraq 1987: Bloody war continues
US-Iraq 2003: War
US-Iran 2003: No War
Iran-Iraq 2003: No War
Why the differences? No single state has become more or less warlike….but the dyads have!
C. Forms of Cooperation
1.
Between Cooperation and Conflict: Bargaining a. Formal Bargaining:
Treaties, etc.
b. Tacit Bargaining:
Reciprocal Action c. Arbitration: Third-party resolution d. Mediation: Third-party support

War – Standard definition is 1000 battledeaths
Militarized Interstate Disputes (MIDs) – use, threat, or display of force

Opposites?

Are these mutually exclusive with the conflict list?

Effects of Joint Democracy: i.
The “Democratic Peace:” Virtually no wars between democracies
• Alleged Exceptions: US-UK 1812 (UK not democracy), UK-Germany
WW1 (Germany not democracy), Finland-UK WW2 (no real combat), Peru-Ecuador (few casualties), India-Pakistan (civilians left out of the loop) ii. Fewer MIDs (1/3 to 2/3 reduction)
• Shift to covert from overt when force is used
• MIDs less likely to escalate to higher levels of violence
• Increased reliance on mediation, arbitration iii. Increased common interests (alliances, UN votes, IOs, etc) iv. Increased Trade – Why should this be?

Even after controlling for democracy / autocracy, similar government mechanisms

Given 100 resources, what can each country produce?
Missiles

USA Colombia
Missiles
OR
Coffee

10 200
•Production possibilities without trade
•Trade allows specialization. US buys
Coffee at < 10 resources. Colombia buys Missiles at < 20 resources.
•Example: Coffee = 1, Missiles = 10.
US trades 5 missiles (50 resources) for
50 coffee (50 resources)
10
100
Coffee

•Result: Both sides can achieve levels of consumption outside of the original production possibilities!

•US has absolute advantage in both goods –
5 to 1 in wheat, 2 to 1 in cars -- so has
comparative advantage (bigger relative advantage) in wheat
•UK has comparative advantage (smaller relative disadvantage) in cars (½ as productive rather than 20% as productive)
•UK buys wheat at < 5 resources,
US buys cars at < 10 resources
•Example: Wheat = 1.5, Cars = 9. US sells
24 wheat (36 resources), buys 4 cars (36 resources)

Bargaining
Conflict
Cooperation
Realists and some Radicals argue that Prisoners’
Dilemma (PD) represents the international system
“Tragedy of (Great Power) Politics” or “class war” i. BUT: Tournament of Strategies showed that when playing repeated PD the best strategy is not “Always
Defect” – it’s “Tit-for-Tat!” ii. Tit-for-Tat = Cooperate, then Reciprocate: Allows cooperation even in the most hostile circumstances BUT also risks escalation
Liberalism argues that few interactions are true PDs and that those that are should be approached with
TFT
Social Constructivism argues that people create these structures, so they can transform them
Bargaining
Conflict
Cooperation a.
b.
Anarchy need not war. Cooperation can evolve even in a world full of PD players!
Institutions and “tying hands” can allow credible commitment, allowing cooperation.
Cooperative “win-win” strategies (maximize joint payoffs) include: i.
Commit to silence in PD (join a gang that punishes squealers) ii. Commit to “no play” in Chicken iii. Commit to take turns in Battle of the Sexes, PD, or
Chicken

Realistic games tend to have an infinite number of possible Nash Equilibria limitations on predictive power
Assumes structure of game is “fixed”
Assumes common knowledge of rationality
– may be problematic (Princess Bride)
B. Empirical Outcomes of
Dyadic Bargaining
Outcomes
1.
Who gets more?
a. More power b. Cost Tolerance: Willing to take losses c. Salience ● Power predicts better than Power alone d. “Tied Hands” and Costly Signals: Ability to convince opponent that further concessions are impossible / unacceptable
2.
Will bargaining fail?
a. Zones of Agreement: Area of mutually acceptable outcomes (better than no agreement – which often means war -- for both sides) b. Expected costs of failure: What happens if there is no agreement?
c. “Shadow of the Future” – Bargaining over future bargaining power (i.e. territory) is most difficult
a.
b.
Economic conflict (tariffs) increased political conflict (and vice versa)
Dyadic war is rare and getting rarer: i. 197 sovereign states 19,306 dyads.
Formula = [n(n-1)]/2 ii. Nearly 1 million “dyad-years” over the past two centuries iii. Less than 1 war per 1,000 opportunities since 1816. 2004-2012 = only 1 interstate war-year out of more than
150,000 dyad-years (Russia vs. Georgia)
Outcomes
Outcomes i.
Total victory uncommon (2/3 end by negotiation) ii. 59% of wars won by initially stronger side -- BUT: initiators of wars victorious 68% of the time, yet only stronger 59% of the time iii. Implication: “Which side started it?” better predicts victory than military power, though advantage declines over time iv. Extension: Democracies win more often, though advantage declines over time (they lose long wars)

1. Ancient Greece:
The Melian
Dialogue
Melians: It may be your interest to be our masters, but how can it be ours to be your slaves?
“The strong do what they will and the weak do what they must.”
Athenians: To you the gain will be that by submission you will avert the worst; and we shall be all the richer for your preservation.
Athens demands submission by
Melians, even though
Melos is insignificant
Melians: But must we be your enemies?
Will you not receive us as friends if we are neutral and remain at peace with you?
Why fight a war over something so small?
Athenians: No, your enmity is not half so mischievous to us as your friendship; for the one is in the eyes of our subjects an argument of our power, the other of our weakness.

No [adequate] attention has been paid to a proposal, extremely important from the military and political point of view, to create a fully automated retaliatory strike system that would be activated from the top command levels in a moment of a crisis.

If communications fail AND nuclear explosions detected by sensors…
Rocket is launched with internal radio
Radio broadcasts launch orders / codes to Soviet

Thus, even if all Soviet leaders killed and communications disrupted, Soviet missiles will annihilate the USA
Problem: They didn’t TELL us about it!
All evidence suggests that Saddam did not expect opposition from the US – misinterpreted generic statement that US doesn’t take a position on the border disputes of other nations as permission to invade

– Ban on direct high-level military contacts
– Ban on some government financing
– suspension of export licenses for satellites contracted to be launched in China
– suspension of export licenses for crime control and detection instruments and equipment
– denial of export licenses for any goods or technology used in nuclear production, if the President finds that such products could be diverted to the research or development of a nuclear explosive device
Outcome: China ignores sanctions, most of which are lifted within a year or two
Iraq Violates the Geneva Protocol,

Iran-Iraq war is intense and bloody
Iraq begins using tear gas, then blister agents, then nerve gas
West is silent because Iran is considered the greater threat
Iran retaliates, but lacked enough chemical weapons to do serious damage
