Six famous negotiations, told simply

Each case takes about five minutes: the story, the game behind it, the big idea, and three questions to check yourself. Read the case before class — the lecture will go much deeper.

CASE 1 · PAYOFF MATRIX · NASH EQUILIBRIUM

Samsung & Apple: sue your customer, supply your enemy

How two companies fought a global legal war and stayed business partners — at the same time.

The story in 60 seconds

APRIL 2011
Apple sues Samsung. It says Samsung copied the iPhone. Samsung sues back. Soon the two companies are fighting more than 50 lawsuits in about 10 countries.
AT THE SAME TIME
Samsung is Apple’s biggest parts supplier. Every year Apple buys about $7–8 billion of Samsung screens and memory chips — the parts inside the iPhone itself.
2011–2014
The legal war continues for three years. The supply relationship never stops. Not even once.
2016–2017
Apple slowly builds other suppliers (LG, BOE, its own chips). Only then does the relationship change.

The game behind the story

People said Samsung was behaving strangely. It was not. Look at Samsung’s choices as a table (points from 0–10, higher is better — first number Samsung, second Apple):

Apple: keep suingApple: settle
Samsung: keep supplying6, 6
what really happened
9, 5
more total value — reached only in 2014
Samsung: stop supplying2, 2
both lose big
3, 4

For Samsung, “keep supplying” is better in both columns (6 beats 2, and 9 beats 3). This is a dominant strategy — the best choice no matter what Apple does. And given that Samsung supplies, Apple prefers to keep suing (6 beats 5) — the lawsuits protected its patents and kept the pressure on. So the lawyers fought, the factories kept shipping, and the game “rested” in the gold cell for three years. That resting point is a Nash Equilibrium.

The big idea: when someone’s behaviour looks irrational, you are probably reading the wrong payoff table. Fix your table, and the mystery disappears.

Also notice the green cell: settling while supplying created more total value (9 + 5 = 14, against 6 + 6 = 12). Why didn’t it happen? Because Apple would lose by moving there alone (5 is less than 6). Nobody volunteers to be worse off. It finally happened when the payoffs themselves changed: by 2014, years of legal costs made settling more attractive to Apple, and the two companies dropped their lawsuits outside the US. Equilibria move when payoffs move — that is what skilled negotiators work on.

Words to know:Lawsuit — a fight in courtSupplier — a company that sells parts to another companyDominant strategy — best choice no matter what the other side doesNash Equilibrium — the resting point of a game

Check yourself

1. Why did Samsung keep supplying Apple during the lawsuits?
Supplying was Samsung’s dominant strategy: 6 > 2 and 9 > 3. No fear, no court order — just payoffs.
2. The gold cell (6, 4) is a Nash Equilibrium. What does that mean?
Equilibrium means stable, not best-for-everyone. The green cell created more total value — but Apple would lose by moving there alone, so the game stayed in gold.
3. What finally changed the game in 2016–17?
Apple changed the numbers in the table by building alternatives. Arguments don’t move equilibria — alternatives do.
CASE 2 · SEQUENTIAL GAMES · NEMAWASHI

Toyota & GM: the deal that was won before the meeting

A 50/50 joint venture where one side quietly held the real power for 26 years.

The story in 60 seconds

1982
GM closes its car factory in Fremont, California. The plant has huge problems: about 20% of workers absent, strikes, low quality.
1984
Toyota and GM open the factory together as a joint venture called NUMMI. Ownership: exactly 50/50.
BEFORE THE DEAL
Toyota spends months quietly preparing: visiting GM factories, talking one-to-one with union leaders, building agreement in private. This Japanese practice is called nemawashi — “preparing the roots before moving the tree”.
1984–2010
The same workers, using Toyota’s system, make the plant one of GM’s best. Toyota effectively leads operations for 26 years. GM never manages to copy the Toyota system into its other factories — and goes bankrupt in 2009.

The game behind the story

On paper, the deal was equal: 50/50. But two hidden mechanisms decided everything.

1 · The real decisions happened before the meeting. Toyota treated the formal negotiation as the last step, not the first. By meeting day, the union, the managers and the plans were already aligned — by Toyota. GM prepared presentations; Toyota prepared people. If you are still making arguments at the formal meeting, you have already lost.

2 · The payoffs arrived at different speeds. Toyota’s goals (learn to build cars in America, work with the union, prove its system abroad) were achieved in 3–5 years. GM’s goal (absorb Toyota’s culture) needed decades. The partner whose goals are satisfied first holds the power in the middle of the relationship.

The big idea: the visible contract said 50/50. The invisible pre-game decided who really led. Always ask: who is playing the pre-game of my negotiation right now?
Words to know:Joint venture (JV) — a company owned by two partners togetherUnion — organisation representing workersNemawashi — building agreement privately before the formal meetingPre-game — everything that happens before the official negotiation

Check yourself

1. What is nemawashi?
Nemawashi is preparation of people, done respectfully and privately. The formal meeting then simply confirms.
2. Why did Toyota gain more from NUMMI than GM?
Same workers, great results — the workers were never the problem. The timing of payoffs was asymmetric.
3. What is the lesson for your own negotiations?
The table is where prepared decisions get confirmed. Prepare the ground, not just the presentation.
CASE 3 · BATNA · ZOPA

Disney & Fox: the $18.9 billion wall move

How one new bidder changed the price of a company by billions in six months.

The story in 60 seconds

DEC 2017
Disney offers $52.4 billion (in shares) for most of 21st Century Fox. Fox has no other serious buyer — its plan B is weak.
JUN 2018
Comcast suddenly offers $65 billion in cash. Fox’s plan B is now excellent. The minimum price Fox will accept jumps overnight.
20 JUN 2018
Disney raises its offer to $71.3 billion — $18.9 billion more than in December.
MAR 2019
The deal completes. Fox chose Disney even though Comcast’s number was cash — read below to see why.

The game behind the story

A deal is possible in the space between the seller’s minimum and the buyer’s maximum — the ZOPA. Those two “walls” are set by each side’s plan B (BATNA). When Comcast appeared, Fox’s wall jumped, the zone moved, and Disney had to follow.

But why did Fox pick Disney? Because a bid is really worth its value × its chance of completing. Comcast’s bid carried bigger regulator risk (maybe ~60–65% chance of completing — an illustrative estimate). Disney’s carried much less (~90%+). Risk-adjusted, Disney’s offer was stronger. And one more thing: Disney’s boss, Bob Iger, had spent about a year building a relationship with the Murdoch family before any offer. Relationships change numbers too.

The big idea: you don’t get a better deal by arguing inside the zone. You get one by moving the walls — improving your plan B, or changing how the other side sees theirs.
Words to know:BATNA — your best plan B if there is no dealZOPA — the price space where a deal is possibleRisk-adjusted — value × chance it really happensRegulator — government body that can block a deal

Check yourself

1. What moved the price from $52.4B to $71.3B?
Nothing about Fox changed — only Fox’s alternative changed. Walls move when plan Bs move.
2. Why could the lower-risk bid beat a similar cash bid?
$65B at ~60% completing is worth less than $71.3B at ~90%+. Always risk-adjust.
3. What did Iger’s year of relationship-building do?
Relationship investment before a negotiation is price-relevant. It is preparation, not decoration.
CASE 4 · SUNK COST · RELATIONAL BATNA

SoftBank & WeWork: the $14 billion “yes” that should have been “no”

Why one of the world’s smartest investors kept paying more for a company that was losing money.

The story in 60 seconds

2016
SoftBank’s founder Masayoshi Son meets WeWork’s founder for 12 minutes — and decides to invest. WeWork rents office space with style; Son believes it is a tech revolution.
2017–2018
SoftBank invests billions. WeWork’s valuation climbs to $20 billion, then higher.
EARLY 2019
Warning signs everywhere — WeWork loses roughly one dollar for every dollar it earns. SoftBank still invests more, now valuing WeWork at $47 billion.
LATE 2019–2020
WeWork tries to sell shares to the public. Investors read the numbers and say no. The value collapses to under $8 billion. SoftBank writes off more than $14 billion (by 2020).

The game behind the story

Son is not stupid. So what happened? Three traps, each one predictable:

1 · Sunk cost. “We already invested billions — we can’t stop now.” But money already spent should never decide the next step. Only the future matters.

2 · Pattern matching. Son once made a quick bet on Alibaba and earned a legend. “Extraordinary founder + fast decision = fortune” became his template. WeWork looked like the pattern — but an office-rental company is not an internet platform.

3 · The relational BATNA. Stopping meant admitting a mistake — in front of his investors, his public image as “the world’s greatest tech investor”, and his own story about himself. His financial plan B said stop; his relational plan B (reputation, relationships, identity) said continue. The relational one won — and cost $14 billion.

The big idea: before re-investing in anything, take the zero test: “If I had zero history here, knowing what I know today — would I still say yes?” Write your answer down, alone, before the meeting.
Words to know:Valuation — the price the market puts on a companySunk cost — money already spent that cannot returnWrite-off — officially accepting a lossRelational BATNA — what leaving really costs: reputation, relationships, face

Check yourself

1. Why is “we already invested billions” a bad reason to invest more?
This is the sunk-cost trap. The correct question is always about the future, never about the past.
2. What is a relational BATNA?
Son’s spreadsheet said stop. His reputation and self-image said continue. Model both — separately.
3. What is the zero test?
It removes the sunk cost and the ego from the decision. The most under-used tool in deal-making.
CASE 5 · PRISONER’S DILEMMA · DEADLINES

Brexit: 45 months of “no” — then a deal in days

Why two rational sides refused to move for almost four years, and what finally unlocked them.

The story in 60 seconds

MAR 2017
The UK officially starts the process of leaving the European Union. Both sides begin negotiating their future relationship.
2017–2020
For 45 months, almost no real movement. The UK government cannot be seen making concessions (“Get Brexit Done”). The EU, with 27 member countries to keep together, cannot be seen rewarding a country for leaving. Both sides hold firm. Both lose value.
31 DEC 2020
A hard, real deadline: with no deal by this date, trade rules collapse for both sides — visibly, immediately, and every politician would be blamed.
24 DEC 2020
Agreement reached on Christmas Eve — one week before the cliff (formally signed 30 December). After 45 months, the final push took only days.

The game behind the story

This is the Prisoner’s Dilemma played by governments. “Cooperate” = make concessions; “defect” = hold firm. Both holding firm was bad for both — but each side’s politics at home made visible concessions feel impossible. In game language: both sides had a low discount factor (δ) — the future mattered less than tomorrow’s newspaper headlines.

The deadline changed everything. Suddenly “no deal” stopped being a tough negotiating pose and became a real, immediate, visible disaster with names attached. Both sides’ δ snapped upward at the same moment — and cooperation instantly became rational.

The big idea: when a negotiation is stuck for months, stop blaming personalities. Ask instead: what is making the future feel unimportant to each side? A real deadline is powerful because it restores the future’s weight for both sides at once.
Words to know:Concession — giving something up to reach agreementDiscount factor (δ) — how much the future matters to a player nowDeadline — a fixed final date with real consequencesTransition period — time allowed for changing to new rules

Check yourself

1. Why did both sides hold firm for 45 months?
Both sides were playing “defect” rationally, given their home audiences. Structure explains what personality cannot.
2. What did the deadline actually change?
A deadline is a delta-restoration mechanism: it makes the future arrive.
3. Your own negotiation is stuck for 90 days. Best first question?
Diagnose δ first. Then raise it, change the payoffs, or create honest urgency — never artificial urgency.
CASE 6 · AUCTION DESIGN · MECHANISM DESIGN

The £22.5 billion auction (and the one that went wrong)

Two governments sold the same kind of licence. One earned five times its estimate. One lost a fortune. The difference was design.

The story in 60 seconds

UK · 2000
Britain auctions five mobile-phone licences (3G). Economists Ken Binmore and Paul Klemperer design the rules. Key move: one licence is reserved for a new company — so the four big incumbents cannot relax; a fifth serious bidder is guaranteed.
RESULT
About 150 rounds of open bidding. Total raised: £22.5 billion — about five times the government’s early estimate.
INDIA · 2008
India gives out 2G licences without an auction — at 2001 prices, first-come-first-served. Some buyers quickly re-sell their stakes at much higher market prices.
AFTERMATH
The national auditor later estimates the value lost at up to ₹1.76 trillion (a contested, “what-if” upper estimate). The Supreme Court cancels 122 licences in 2012. A criminal trial ends in acquittals in 2017. The episode remains the textbook example of allocation without competition.

The game behind the story

The UK auction worked because of three design choices: guarantee real competition (the reserved licence), let bidders learn from each other’s bids (open rounds reduce the fear of over-paying), and commit to the rules (nobody could negotiate a special deal afterwards).

India’s process removed the auction — but competition did not disappear. It moved: from open bidding, where competition creates public value, to queue-jumping and connections, where it creates private value. That is the deep lesson: you cannot delete competition; you can only choose where it happens.

One warning for bidders: in auctions where the prize’s value is the same for everyone (a licence, an oil field), the winner is usually the bidder with the most optimistic estimate. This is the winner’s curse — winning can mean over-paying. Professionals bid below their estimate on purpose.

The big idea: whoever designs the rules of a game decides where the competition goes. Design your supplier selections, sales processes and tenders as carefully as you would play them.
Words to know:Auction — a sale by competing bidsIncumbent — a company already in the marketWinner’s curse — winning by being the most optimistic — and over-payingMechanism design — designing the rules of a game to get a good outcome

Check yourself

1. Why was reserving one licence for a new company so powerful?
Entry design is everything: without guaranteed competition, incumbents can relax and prices stay low.
2. What happened to competition when India removed the auction?
“When you remove the auction, you don’t remove the competition. You redirect it.”
3. You are bidding for an oil field. Your analyst says it is worth 100. What do you bid?
Winner’s curse discipline: shade your bid — more when uncertainty is high and bidders are many.
