Preparing for exams can feel like trying to solve a puzzle with missing pieces. When it comes to a specialized subject like the Economics of Information, standard textbooks sometimes aren’t enough to give you a clear picture of what to expect on test day.
That is exactly where practicing with actual exam questions comes into play. To help you bridge the gap between theory and exam success, we are breaking down what this subject is all about and showing you how to get your hands on the ultimate study resource.

Your Guide to Mastering the Economics of Information
What exactly is the Economics of Information?
In traditional economics, many classic theories assume that everyone in a market has perfect knowledge. In the real world, that rarely happens. The Economics of Information is a branch of microeconomics that studies how uncertainty and information disparities affect economic decisions and market outcomes. It looks at what happens when one party knows more than the other and how society builds mechanisms to overcome these gaps.
Why is this subject considered so challenging?
Students often find it tricky because it moves away from straightforward supply-and-demand graphs. Instead, it forces you to think strategically about human behavior. You have to analyze how people act when they are hiding information or when they cannot verify the quality of what they are buying. It requires a mix of logical reasoning, game theory, and psychological awareness.
What are the core concepts I need to know for the exam?
While curricula vary, a solid past paper on this subject will almost always test you on a few foundational pillars:
-
Asymmetric Information: This occurs when one party in a transaction possesses more or better information than the other.
-
Adverse Selection: A situation where market mechanisms lead to an unfavorable selection of buyers or sellers (often illustrated by George Akerlof’s famous “Market for Lemons” car example).
-
Moral Hazard: This happens when an entity has an incentive to take risks because the negative consequences of those risks will be borne by someone else (classic in insurance markets).
-
Signaling and Screening: The methods used by informed parties to credibly reveal their information (like getting a degree to signal high ability) and by uninformed parties to uncover hidden information.
Why should I use past papers to revise?
You can read a textbook front to back, but the exam does not ask you to just repeat definitions. It asks you to apply these theories to specific scenarios. Past papers train your brain to recognize which concept applies to which problem. They also help you master time management so you are not left rushing through the final questions when the clock is ticking down.
How can I access quality revision materials?
The best way to prepare is to test yourself under real exam conditions. We have gathered comprehensive resources to make your study sessions highly effective.
Quick Tips for Your Revision Session
-
Replicate the environment: Sit in a quiet room, put away your notes, and set a timer.
-
Grade yourself harshly: Use the marking scheme if available, or compare your answers directly to your core course texts to see where you missed nuance.
-
Focus on your weak spots: If you consistently lose points on moral hazard questions, dedicate your next study block specifically to that topic before attempting another full paper.
