The 2025 Econ Camp is taught by Professor Emir Kamenica for incoming PhD students at Booth. This year, first-years from Griffin and Harris also joined, making the room a cross-department gala of future scholars craving for free coffee. The camp runs for an intensive week, with three hours of lectures every morning.

At the Econ Department… Thanks to Professor Kamenica’s exceptionally clean logical organization, these notes preserve the blackboard style.
The following is a catalog of my notes from class. They aim to preserve the “chalkboard clarity” of Professor Kamenica’s lectures. Which says, these are not polished essays but a structured record of the logical flow: definitions, theorems, and occasionally examples.
