No worries @aumkarbhave6737, here's Part 2, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Uip1ULExQUw.html. I'll start on Part 3, hopefully won't be too long.
Hi! I am able, but I probably won't be very quick (cards on the table, behavioural economics is not my favourite, I've only taught it once, so it might take me a little while to get my thoughts together). Feel free to e-mail me with more specific questions though (what textbook you use, topics covered etc), that will help me understand what you need, and I will be able to figure out if I have any insight (or not, as the case may be) that I can put together in a video. :) EMAIL: econmathhelp@gmail.com
