This course, structured as a seminar, will explore foundational questions concerning prices and pricing, as well as the transactions, relationships and institutions in which they appear. Basic questions we may explore include: Why have prices at all? How does price-setting occur (in theory and practice)? How should it occur? What are appropriate and realistic social goals relating to prices? Who are the actors engaging in price-mediated transactions — natural persons and households, business firms, and others — from a legal, economic and social perspective? We will consider perspectives on prices drawn from various areas of law and policy and from a variety of perspectives and traditions in economic and legal thought. At a minimum, this will include close engagement with prevalent or “textbook” approaches to many of these issues; their assumptions and foundations; as well as important objections and possible alternatives. Selected policy applications and current issues — potentially including labor relationships, essential consumer goods, and international trade — may further inform our discussions.
