liu metivier says:

can someone explain why it is unrealistic for it to be linear ? and more
likely to be concave ?

p.s very helpful video =] 

Fariza Utepbayeva says:

thank you very much. it was really helpful

Noore Tautaya says:

when production of cheese increases the opportunity costs of wool increases
on the upper part of the x – axis and not as shown on the demo video

Melissa Roberts says:

This guy defines his own rules of economics. Normally, when quantity
increases, price increases. So how come almost 200,000 people want to watch
this video tutorial, and it remains free?

darandonman says:

I have a question On a concave PPF, does the opportunity cost ALWAYS
increase as the output of the good/service on the ‘y’ axis increases?

CWRT says:

He taught this better in 5 minutes than my teacher did in 40.

QuickBricks288 says:

Thank you so much for explaining this to me!! I could not find a meaning I
understood on any websites about opportunity cost!

Luis T. Puig says:

Productivity is a result of Efficiency, and not energy efficiency like some
are talking right now, but COMPLETE Efficiency…if you don’t know the
Baselines of your business how can you improve it?… if your Equipment
isn’t kept and operated properly how can you depend on it?…if your
organization has no effective worker’s communication & training how can you
get people to do the right things?…get it? Process, Equipment, Personnel,
the core elements… get the Industrial Efficiency Triangle.

Dhaamin Samsoodeen says:

Thank you for all the great videos it helped me a lot. Thumbs up :)

Rafael Morseletto says:

Why does the opporunity cost curve make a concave, but the indifference
curve makes a convex? It seems like almost the same to me.

pajholden says:

@Tosnel Hi – thank you for your kind comments. I used to work in the UK. I
was a stand-up comedian for a year, then got into teaching. I taught in a
tiny language school in a mountain town in Arcadia, Greece for a year, fell
in love with teaching and Greece, came back to the UK and taught History
for three years in state schools in Dagenham and Morecambe. But Greece was
in my blood by then, and kept calling me back, so I moved to Athens
permanently in 1996.

amy chang says:

ThatDrumBoy says:

Bianca Hock says:

Thank you for your help! I am a student at Ucla and we covered this topic
in my World Politics course for our Global Trade chapter— I’m not an
economics major, but your way of explaining clarified things very well :)
Thanks again!

I could only lean on one example of OC but now I see that it also applies
to production and manufacturing lines. It’s like I had been living in a
flat earth before this video.

kcathcar says:

this guy is good. thanks for the videos.

weirdshibainu says:

hey blurock, it may be simple but you’d be surprised at how many businesses
particularly small businesses that have never heard of opportunity cost let
alone attempt to make a singular choice on 2 or more competing

THANK YOU SIR! You should be my teacher!!! I am doing Economics for the
first time in A levels and my teacher has already made it clear tha she
will only teach us the basics and we will have to get into the depths
ourselves 😐 I am quite bad at anwering questions or exam type case
studies. Will you be able to make a video on writing modal answers? Thank
