What are some real-world examples of Nash Equilibrium?

A classic example is the Prisoner's Dilemma, where two criminals must decide whether to cooperate or betray each other.

Can you explain the Prisoner's Dilemma in more detail?

Sure! In the Prisoner's Dilemma, two suspects are arrested and interrogated separately. If both remain silent, they get a light sentence. If one betrays the other, the betrayer goes free while the silent one gets a heavy sentence. If both betray, they both get moderate sentences. The Nash Equilibrium occurs when both betray, as neither can improve their situation by changing their strategy alone.

Are there other examples outside of criminal scenarios?

Yes! Another example is in business, where companies may choose to set prices. If both set high prices, they maintain profits. If one lowers prices while the other keeps them high, the low-price company gains market share. The Nash Equilibrium is when both set high prices.

How does this apply to everyday decision-making?

In everyday life, Nash Equilibrium can be seen in situations like traffic flow, where drivers choose routes. If everyone chooses the same route, it becomes congested, but if they spread out, travel times improve. The equilibrium is reached when no driver can reduce their travel time by changing routes alone.
