Enhanced Predictive Power of Dominant Strategy Equilibria
While a unique Nash equilibrium is a good predictor of a game's outcome, a dominant strategy equilibrium offers an even more reliable prediction. This heightened confidence arises because each player's optimal choice is their dominant strategy, which remains the best action regardless of their opponents' decisions. This makes the equilibrium outcome particularly robust and predictable.

Designing Games with Varying Equilibrium Plausibility
A game is known to have only one Nash equilibrium. Match each characteristic of how that equilibrium is reached with the corresponding level of confidence an economist would have in predicting it as the actual outcome.

Evaluating the Predictive Power of a Unique Nash Equilibrium
Enhanced Predictive Power of Dominant Strategy Equilibria
In a strategic interaction between two competing firms, the only outcome where neither firm has an incentive to unilaterally change its strategy is when both choose a 'Low Price'. Why does this single stable outcome serve as a strong prediction for how the firms will behave?
Learn After
Consider two strategic scenarios, Scenario X and Scenario Y.
- In Scenario X, a firm's profit-maximizing advertising budget is $1 million, regardless of whether its main competitor advertises heavily, moderately, or not at all.
- In Scenario Y, a different firm's profit-maximizing advertising budget is $1 million only if it correctly anticipates that its competitor will also spend $1 million on advertising. If the competitor chooses a different budget, the first firm's best response
Comparing Predictive Confidence in Strategic Scenarios
Assessing Predictive Confidence in Strategic Outcomes
In a strategic interaction between two firms, an outcome where Firm 1's chosen action is optimal only if it correctly anticipates Firm 2's action is just as reliable and predictable as an outcome where Firm 1's chosen action would have been optimal regardless of which action Firm 2 had chosen.
Predictive Certainty in Strategic Interactions
Analyze the following four strategic situations. Match each situation with the statement that best explains the reliability of predicting its outcome.
An economist is analyzing two potential market scenarios for two competing firms. In each scenario, the firms must simultaneously choose a strategy. The text below shows the profits for each firm, (Firm 1, Firm 2), in millions of dollars based on their choices.
