Let’s be honest: in standard economics, we often pretend everyone has “perfect information.” We imagine buyers and sellers meeting in a sunlit market where everyone knows exactly what a product is worth. But Economics of Information pulls back the curtain on the real world—a world that is messy, lopsided, and full of “hidden” truths.

If you’re preparing for your finals, you’ve likely realized that information isn’t just a commodity; it’s a power dynamic. One minute you’re discussing why a used car might be a “lemon,” and the next you’re calculating the value of a degree as a “market signal.” It’s a subject that requires you to think like a strategist, a psychologist, and a mathematician all at once.
To help you balance the scales of knowledge, we’ve tackled the high-yield questions that define the syllabus. Plus, we’ve provided a direct link to download a full Economics of Information revision past paper at the bottom of this page.
Your Economics of Information Q&A: Thinking Beyond the Price
Q: What is “Asymmetric Information,” and why does it break the market? Asymmetric information occurs when one party in a transaction knows more than the other. This leads to two classic exam “monsters”: Adverse Selection (happens before the deal, like a sick person buying insurance) and Moral Hazard (happens after the deal, like someone driving recklessly because they are insured). In an exam, if you’re asked how to “fix” this, remember the terms Screening and Signaling.
Q: How does “Signaling Theory” explain why we go to university? In this unit, a degree isn’t just about what you learned; it’s a signal to employers that you have the discipline and intelligence to finish a hard task. Because it is “costly” (in time and money) for a low-ability person to get a degree, the degree serves as a reliable signal of high ability. Expect an exam question asking you to contrast the “Human Capital” view vs. the “Signaling” view of education.
Q: What are “Network Effects,” and how do they create monopolies? Information goods often have network effects—the more people use a product (like WhatsApp or LinkedIn), the more valuable it becomes for everyone else. This leads to “Lock-in” and “Switching Costs.” In an exam, if a question asks why a technically inferior product stays at the top of the market, the answer is usually found in the power of the network.
Q: Why is “Pricing Information” so different from pricing a loaf of bread? Information has a unique cost structure: High Fixed Costs (it costs a fortune to produce the first copy) and Low Marginal Costs (it costs almost nothing to copy and distribute it). This is why information companies love Versionings (offering “Premium” vs “Basic” versions) and Bundling (selling a group of products for one price).

Strategy: How to Use the Past Paper for Maximum Gain
Don’t just read the PDF; treat it like a game theory simulation. If you want to walk into that exam hall with an edge, follow this “Economist” protocol:
-
The “Lemon” Calculation: Look for a question on the Market for Lemons. Practice explaining why a market might collapse entirely if buyers can’t tell the difference between high-quality and low-quality goods.
-
The Principal-Agent Problem: Take a scenario from the paper (e.g., “A shareholder and a CEO”). Identify the Incentive Conflict. How would you design a contract (using bonuses or stocks) to make sure the Agent acts in the Principal’s best interest?
-
The Intellectual Property Debate: Be ready to discuss Copyright and Patents. Do they encourage innovation by protecting the creator, or do they hurt the economy by creating “Deadweight Loss”?
Ready to Master the Market of Knowledge?
The Economics of Information is the lens through which we understand the modern digital economy. It explains everything from why we trust online reviews to how Silicon Valley giants maintain their grip on the world. By working through a past paper, you’ll start to see that the “cost” of information is often much higher than the price we pay.
We’ve curated a comprehensive revision paper that covers everything from Search Costs and Experience Goods to Information Cascades and Game Theory.
