great guy. very helpful during office hours. MT 25%, HW 25%, Final 50%. the final was very straightforward. class is not curved but his grading scale is pretty generous (80% = A). he's a funny guy and nice enough to go over some basics for those of us who've forgotten. don't be afraid to ask for help! i struggled at first and got a C on the midterm, then i started going to office hours every week to get help and i was able to get an A in the class. the topics are interesting (lotteries, insurance, investing). most students were math-econ, but just econ students can definitely keep up too!

Fall 2025 - This class is borderline unbearable (Econ 142 Economics of Networks). Unfortunately, Obara's lectures are convoluted, directionless and confusing. He reads off the slides all class, does very few in-class examples and is often corrected by students for mistakes he makes himself. The midterm looked similar to the singular practice exam he gave, but to figure out any of the answers you must look online, you will not find helpful examples or directions from the slides. Moreover, the content is straight up boring. It attempts to combine game theory and matrices, but generally teaches you nothing. I would not recommend this class for a student who wants to learn OR for a student who simply wants to register for any easy class.

This class was the best class I took at UCLA. Segal was an amazing teacher, and I'm really glad I took him. Although the class was very mathematical, he made it very applicable to real life, and therefore more enjoyable to learn. He always kept the students involved and was very clear and concise. Furthermore, his tests were very fair and he had an easy grading curve. Although he was amazing for our small econ 142 class (only 30 students), I heard he wasn't as effective in his larger econ 11 class although still pretty good. Overall though he really cares about his students and is a very very good professor.
