My topic: Strategic Games (A Nash equilibrium is a pair of strategies, one for each player, in which each strategy is a best response against the other). When players act rationally, optimally, and in their own self-interest, it’s possible to compute the likely outcomes (equilibria) of games. By studying games, we learn not only where our strategies are likely to take us, but also how to modify the rules of the game to our own advantage. Equilibria of sequential games, where players take turns moving, are influenced by who moves first (a potential first-mover advantage, or disadvantage), and who can commit to a future course of action. Credible commitments are difficult to make because they require that players threaten to act in an unprofitable way—against their self-interest.

The concept of strategic games and Nash equilibrium plays a fundamental role in understanding decision-making processes in competitive environments. A Nash equilibrium, as defined by John Nash (1950), occurs when each player's chosen strategy is the optimal response to the strategies of other players, resulting in a situation where no player has an incentive to unilaterally change their decision. This equilibrium concept informs the analysis of rational behavior in various strategic settings, from economics and politics to everyday interpersonal interactions.
One illustrative example of a strategic game is the Prisoner's Dilemma, where two players face the choice of cooperating or defecting. Mutual cooperation leads to a collectively better outcome, but rational self-interest drives each player toward defection, often ending in a suboptimal Nash equilibrium. This exemplifies how individual incentives can lead to outcomes that are not socially optimal, highlighting the importance of understanding strategic behavior and the potential for intervention through rule modifications or enforcement.
Sequential games, where players move in turns, are particularly interesting because they introduce elements such as the timing of moves and the ability to make credible commitments. For example, the first-mover advantage suggests that the initial player may secure a favorable position by acting first, potentially committing to strategies that influence subsequent moves. Conversely, a first-mover disadvantage can occur if the initial move exposes vulnerabilities that opponents can exploit. Crocker (2017) emphasizes that in sequential games, the ability to commit credibly to future actions is crucial, as it can alter the strategic landscape by influencing opponents' expectations and responses.
Credible commitments are often difficult to establish because they require players to threaten or promise actions that are contrary to their immediate self-interest. For instance, a firm might commit to a costly advertising campaign to deter entrants, but such a commitment only attains credibility if it is believable and enforceable. In game theory, the credibility of threats and promises significantly affects strategic stability and outcomes (Fudenberg & Tirole, 1991). The capacity to credibly commit can shift the equilibrium, enabling players to coordinate on more Pareto-efficient outcomes.
Furthermore, the study of modifications to game rules illustrates how strategic environments can be manipulated to favor certain outcomes. For example, auction rules can influence bidding strategies and revenue outcomes. Similarly, regulations that alter payoff structures or introduce binding commitments can make equilibrium outcomes more desirable from a social or individual standpoint. Such interventions demonstrate the practical importance of understanding game mechanics and strategic incentives, as they allow policymakers and participants to steer results toward more optimal solutions.
In conclusion, the analysis of strategic games, including the concept of Nash equilibrium, provides profound insights into rational decision-making. Recognizing the influence of move order and credible commitments reveals how strategic advantages can be leveraged, and how rules can be designed or altered to achieve more favorable outcomes. These principles are applicable across diverse fields, illustrating the pervasive nature of strategic thinking in shaping human interaction.
