Club Meeting 8th Feb 2022

The theme for tonight’s meeting was “Game Theory”. Game theory is a framework for understanding choice in situations among competing players. Game theory can help players reach optimal decision-making when confronted by independent and competing actors in a strategic setting.

Table Topics

During Table Topics, Mark Paton randomly picked audience members to deliver a 1 minute speech on how they would deal with each situation by using game theory. The question not only tested our impromptu public speaking skills, but also listening and problem solving skills! Anyone who participated in Table Topics is probably now an expert at Game Theory! Here were some of the questions:

  1. Prisoners Dilemma – You have committed a serious crime with your best friend – possession of drugs. If you cooperate with the investigation, you will go free and your best friend will go to jail for 20 years. If you keep your mouth shut and don’t cooperate with the investigation, you both get 2 years each. What will you choose?
  2. Cournot Competition – You are one of only two players in the market selling the new and exclusive next-gen smartphones. You can either flood the market with 1,000 phones and sell them for $1,000 each and make $1M. Alternatively, if you only produced 200 phones you would need to sell them for $5,000 or more each. You do not know how much your competitor is selling them for or how much they are producing. What do you do?
  3. Centipede Game – The maximum prize is $5,000 and will go to either yourself or your best friend.
    • Scenario A; You take $5,000, your friend decides to give it to you, you keep $5,000
    • Scenario B: You give your friend the money, your friend decided to give you the money and you win $10,000
    • Scenario C: Both take the money and both get $0.
  4. Dictator Game – Your best friend has been given an unknown sum of money. He or she will give you part of it and keep the rest. If you don’t accept the amount your friend gets nothing. Your friend offers you $500. Do you accept?
  5. Nash Equilibrium – You have a one of a kind smartphone that allows you to teleport yourself from place to place. This is sold for $5,000 per phone and costs you $2,500. A competitor is coming into the market and is planning to undercut you. Their cost is $3,500 and they plan to sell for $4,000. Do you sell for $3,499 destroy your competition and loose profitability or keep your price and margin and allow them to enter.
  6. Coordinator Game – There are 2 smartphone providers in the market. A new microchip technology is available.
    • If both companies introduce this, they will make $600M each.
    • If only one company introduces this they make $150M.
    • If no company introduces this you will continue making $300M

Word of the Night

Satoshi was the word that Chris asked everyone to use as much as possible tonight. A satoshi is the smallest unit of the Bitcoin cryptocurrency. It is named after Satoshi Nakamoto, the creator of the Bitcoin protocol.

Example Usage:

  • “I just had a satoshi moment. I finally understood how to solve the problem. This is going to be big.”
  • “Here’s my two sats” – same usage as “here’s my two cents”, but the unit is in satoshis (abbreviated as sats) instead of cents.
