Adverse Selection: How Hidden Information Destroys Markets and What Can Be Done About It
When one side of a transaction knows something the other does not, markets can unravel from the inside. This lesson traces adverse selection from Akerlof's Nobel Prize-winning lemons model through health insurance death spirals, the 2008 financial crisis, and rural credit markets in Bangladesh, building to a practical toolkit of signaling, screening, and policy responses that shape markets from Nairobi to New York.

Auctions and Bidding Strategy: The Economics of Competitive Price Discovery
From the Aalsmeer flower clock to Google's trillion-dollar ad market, auctions are the economy's most powerful price-discovery machines. This lesson builds from the four canonical auction formats through the Winner's Curse, bid-shading strategy, and collusion risks, culminating in the Nobel Prize-winning spectrum auction designs that reshaped how governments allocate scarce resources. Students leave with both the theory and the strategic instincts to analyze any competitive bidding environment.

Behavioral Responses to Taxation: How People Actually React When the Rules Change
Tax policy rarely produces the outcomes its designers predict, because people are not passive recipients of new rules. This intermediate microeconomics lesson traces the full spectrum of behavioral responses to taxation, from labor supply adjustments and income retiming to corporate profit shifting and geographic mobility, using real natural experiments from Denmark, Sweden, the UK, the United States, and beyond. By the end, you will be able to evaluate any tax reform proposal not just by its stated rate changes but by the behavioral landscape it will actually produce.

Capital and Wealth Taxation: Power, Mobility, and the Limits of Redistribution
Wealth concentration is rising across the globe, public support for taxing the rich is broad, and yet wealth taxes keep failing, being repealed, or raising far less than projected. This lesson moves from the real-world experiences of Norway, France, South Korea, and Argentina through the theoretical debates between Piketty, Chamley-Judd, and Mirrlees, to the structural problems of capital mobility, offshore havens, and political economy that explain the gap between what voters want and what governments can deliver. By the end, you will be able to evaluate any wealth tax proposal against the constraints that have defeated most of its predecessors.
