Jay is one of the most engaging professors in the Econ department and gives very good lectures. More than every other professor I had, he liked to stop and ask questions throughout every lecture to clarify concepts and motivate students to think. Class attendance was very high even though slides were posted online. The problem sets and exams were decently challenging (not easy, not hard). And the examples he gave were actually relevant to real life (ie. procrastination, investment, dating).

Behavioral Economics is a relatively "new" subject that merges classical economics with psychology. Jay did a great job structuring the main themes so that every theme was covered with the following format: 1) what does classical economics say? 2) why classical economics sucks, and 3) how is behavioral economics better? It's really easy to follow along, but you had to spend some time digesting the concepts. The math is relatively simple (algebra and basic differentiation) but the concepts could get dense so make sure you figure out the precise relationship between different ideas.
