This was by far the WORST CLASS I ever took at Columbia. It also prompted me to write a review on culpa for the very first time in my four years of college.
This was a class for the SEAS students and MSORs, and the professor is new. Honestly, I learned nothing from this class. The entire lecture could be summed up to less than half a page for most days.
Explanations about homework frequently too,k up half the class time. Instead of explaining something in detail in class, the professor just directed us to the chapter and page in the textbook, and posted some presentation slides from elsewhere for us to catch up on. Since he repeatedly told us how he thought our textbook is "rubbish and not helpful," this wasn't very helpful in convincing me that I was learning something. The way he would just reference everything to the book without discussing it also made me doubt why we had class time at all in the first place.
We were repeatedly nagged upon, sometimes for minutes on end and abruptly in the middle of lectures, about cell phone use or other actions in class that he thought was "disrespectful to yourself, me and all of your classmates," while the rest of the class was waiting to learn something. The professor was hard to reach as well, and even if we asked questions via email like he instructed, it took a while for him to get back to us. Considering that he doesn't have office hours or has the CA to cover his absence on campus, this was very inefficient.
He utterly failed to schedule the second midterm, and so it turned out to be on the last day of class.
The professor is especially not open to student opinions about the course, and sticks to his own decisions for regardless of the students. Very stubborn about his methods and grading, and students even had a lunch discussion with an IEOR advisor to complain. Compared to the other economics classes that I have taken, this course by far covered the least course material, especially in class.
In sum: If you want to learn something, don't take this professor. If you want to have a professor who is at least reasonable and knowledgable, don't take this professor.
