New Market Design with Terence Johnson is 100% the best 4000 level econ class you can take at UVA!! It is actually enjoyable and you can succeed in it unlike many other econ classes. Professor Johnson is one of UVA's best teachers and truly does everything he can to help everyone do well in the class. The exams are super fair and if you just understand the main picture, you will do fine on all of the exams. Definitely my favorite Econ class I've taken and the information is actually very interesting.
