Uncover the economics of pricing power, barriers to entry, and the legal battle against monopolies.
This course explains what market power is, where it comes from, and how it affects prices, profits and the law. It builds on the supply and demand model from Course Two, but no earlier course is required.
The first part covers the core economics: why a seller with market power faces a downward-sloping demand curve, why marginal revenue is below price, how the firm chooses its price and output, and the difference between the transfer from buyers to sellers and the deadweight loss. The markup rule links the size of a markup to the elasticity of demand the firm faces, and each step is worked through with numbers.
The second part covers pricing and competition among a few firms: price discrimination, versioning, dynamic pricing and drip pricing; the cartel’s dilemma and why cartels survive when prices are visible; leniency programmes; and coordination through shared pricing software. Cases include the Canadian bread price-fixing case, the lysine cartel and RealPage.
The third part covers barriers to entry and what they mean for valuation, including network effects in payment cards, default agreements in the Google search case and grocery property controls in Canada. It also reviews the evidence on rising markups and on whether markups drove recent inflation, and explains why a markup is not the same as a gross margin.
The final part sets out competition law in Canada and the United States side by side: the Competition Act, the Sherman Act and the Clayton Act, Canada’s recent amendments, the HHI and the merger thresholds both countries now use, abuse of dominance, and how overcharges and pass-on are estimated in damages cases. The course returns to the Live Nation verdict and the remedies under discussion, and ends with regulated natural monopolies and a valuation case.
Six think questions let you apply each idea before the answer is given. The course is economics education, not legal advice.
Associate Professor of Economics | King's University College at Western
#Dr. Jason Dean **Associate Professor of Economics and Applied Economist** Dr. Jason Dean is an Associate Professor of Economics at King’s University College at Western University and holds a PhD in Economics from McGill University. He teaches university students and working professionals, drawing on experience in academic research, economic consulting, public policy and the practical use of artificial intelligence. His CPD work covers applied economics and emerging AI tools. His approach is practical and evidence-based: explain how something works, identify the assumptions and limitations, and give learners a framework they can use in their own work. Jason has worked extensively with generative AI since the emergence of ChatGPT, incorporating it into teaching, research and professional education. He has delivered three presentations for Haver Analytics, most recently a June 2026 session on Model Context Protocol (MCP) servers. He has also presented on AI for the Canadian Chamber of Commerce and the Toronto Association for Business and Economics. His presentations have covered AI productivity tools, copyright, privacy, emerging capabilities and the practical implications of using AI in professional work. Before joining King’s, Jason worked as an associate and health economist at Analysis Group and as an economic research analyst at CEP News. His consulting work contributed to published studies of healthcare costs and treatment outcomes. He has also taught economics to CPA students at Sheridan College. Jason’s teaching career has taken him across Canada, Japan and China. In 2024, he was a visiting professor in Canadian Studies at Kwansei Gakuin University in Japan, where he taught Canadian Business Culture and Canadian Economic History. He has also taught Labour Economics at Wuhan University of Technology and Labour Economics and International Trade and Finance at Renmin University in Beijing. His experience teaching in China later prompted him to develop his Economics of China course at King’s. His Canadian teaching experience also includes Wilfrid Laurier University, McMaster University Continuing Education and McGill University. Jason has contributed assessment questions, digital learning activities and instructional materials to economics resources for McGraw-Hill and Pearson. His research examines questions with practical consequences for households, workers and employers. What happens when immigrants cannot find work related to their education? How does a fall in income affect a renter’s ability to move? Do Canadian housing and stock markets share a long-run relationship? His work has appeared in journals including *Applied Economics*, *Regional Science and Urban Economics*, *Cliometrica* and the *Journal of Housing Economics*. As an Associate Researcher with the Montreal Economic Institute, Jason studies how taxes and benefit reductions affect the financial return to work. His policy publications examine the circumstances of low-income seniors, people taking second jobs and workers moving off income assistance. He has also provided media commentary on housing, labour markets, artificial intelligence and the Canadian economy. Jason also holds an MA in Economics from the University of Guelph and an Honours BBA from Wilfrid Laurier University. --- ## MONTREAL ECONOMIC INSTITUTE | RESEARCH REPORTS - **“End Penalties That Punish Low-Income Seniors Who Work”** (2026), with the collaboration of Gabriel Giguère. - **“The Benefits of Eliminating the Middle-Income Tax Bracket”** (2025), with the collaboration of Emmanuelle B.
