  • Even my teacher recognises that you're better than he is. At the beginning of every topic, if there's something difficult to explain then he just says "Boys, let's get Big Phil Holden to explain it"

  • @Charlieboy4444 Thanks Charlie - say hello to your teacher for me.

  • I was told it is costs and output on the axis. Confusing.

  • Great teacher, got me through my International Baccalaureate and now getting me through my degree! thank you so much, please dont stop! :)

  • i just love your videos they are so helpful thank u so much :))

  • I think i love you at the moment

  • where do you teach?

  • U said that it was most students found themselves baffled that when the supply increased in the industry, the supply by each firm decreased...Isn't that because new firms have entered the market attracted by the abnormal profit. In this way the suppliers have increased. So if suppliers are increased, then wouldn't it make sense that even if the supply of each individual firms has fallen, overall the supply has increased due to the new firms entrance....

  • what is the difference between long run equilibrium and short run equilibrium. I know that in the long run equilibrium abnormal profits are impossible in perfectly competitive markets, but is that the only distinguishing feature???

  • @abdullah7200

    Perhaps you should learn that it is 'economics' first. Just kidding xD. Great videos Sir! I study economics without a teacher or a university too xD

  • @pajholden I'm an IB student who was struggling as hell to make it through my 2 years... you came along and now my predicted is a 6! Thank you soo much! You honestly saved my diploma!
