24 - Asymmetric information: auctions and the winner's curse
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, sec

The Joy of Economics: Making Sense out of Life
My goal is to provide an accessible book that reflects this theme of choice and conveys a sense of the breadth and power of basic economic analysis. It assumes no prior knowledge of economics and can be read and appreciated by anyone. While some parts of the book cover conventional material, others do not. I've ignored many traditional topics and substituted ones that apply economics in unusual and often provocative ways. The chapters are not meant to be definitive, they are meant to raise q
