Lecture 24 - Asymmetric Information: Auctions and the Winner's Curse

Author: William Sheppard June 8, 2018 Duration: 1:02:28
We discuss auctions. We first distinguish two extremes: common values and private values. We hold a common value auction in class and discover the winner’s curse, the winner tends to overpay. We discuss why this occurs and how to avoid it: you should bid as if you knew that your bid would win; that is, as if you knew your initial estimate of the common value was the highest. This leads you to bid much below your initial estimate. Then we discuss four forms of auction: first-price sealed-bid, second-price sealed-bid, open ascending, and open descending auctions. We discuss bidding strategies in each auction form for the case when values are private. Finally, we start to discuss which auction forms generate higher revenues for the seller, but a proper analysis of this will have to await the next course.

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.

 - Subgame Perfect Equilibrium: Wars of Attrition [not-audio_url] [/not-audio_url]

Duration: 1:15:36
We first play and then analyze wars of attrition; the games that afflict trench warfare, strikes, and businesses in some competitive settings. We find long and damaging fights can occur in class in these games even when…
