Lecture 10 - Mixed Strategies in Baseball, Dating and Paying Your Taxes

Author: William Sheppard June 4, 2018 Duration: 1:13:31
We develop three different interpretations of mixed strategies in various contexts: sport, anti-terrorism strategy, dating, paying taxes and auditing taxpayers. One interpretation is that people literally randomize over their choices. Another is that your mixed strategy represents my belief about what you might do. A third is that the mixed strategy represents the proportions of people playing each pure strategy. Then we discuss some implications of the mixed equilibrium in games; in particular, we look how the equilibrium changes in the tax-compliance/auditor game as we increase the penalty for cheating on your taxes.

Ever wondered how the strategies behind a high-stakes poker game, a political campaign, and a corporate merger might actually be connected? Yale Open Courses ECON 159: Game Theory, presented by William Sheppard, pulls back the curtain on the fascinating science of strategic decision-making. This isn't just an academic lecture series; it's a deep dive into the frameworks that explain how we interact when our choices directly impact others. Each episode unpacks core concepts-from Nash equilibrium and backward induction to credibility and signaling-using clear explanations that make these powerful ideas accessible. You’ll hear these theories brought to life through engaging examples that stretch far beyond textbook economics. Discussions might pivot from classic parlor games to analysis drawn from film narratives, historical events, and current political dilemmas, showing just how pervasive strategic thinking is in our world. The content is drawn directly from the renowned Yale College course, capturing the dynamic atmosphere of a campus classroom. For anyone curious about the hidden rules of competition and cooperation in everyday life, this podcast serves as a compelling guide. Tune in to train your mind to see the strategic layers in everything from simple interactions to complex global systems.

We introduce Game Theory by playing a game. We organize the game into players, their strategies, and their goals or payoffs; and we learn that we should decide what our goals are before we make choices. With some plausib…
