Guest heartarcade Posted August 23, 2008 Report Share Posted August 23, 2008 So I'm doing my IA on microeconomics.. and I was wondering if you can move both the supply and demand curves at the same time? My understanding is that you can't but in the example that the IBO gives out (the one that was awarded full marks) the person moved both.

How would u apply a shift in any of the curves? There are factors right? Like for demand curves, Complement and substittute goods would shift your demand curve and cost of production would also shift the supply curve. So if both happen in one scenario, then im sure u can shift both. Perhaps u are confused with change in demand curve and change in quantity demanded?

pretty_ah_boi Posted August 24, 2008 Report Share Posted August 24, 2008 oh ok i understand what you mean. well, if in your IA, it satisfies the reasons for a shift in demand and supply curve then i suppose that it is possible to shift them both at one time. The theory justifies it. Btw, what textbook are you using? Reply Link to post Share on other sites More sharing options...
deissi Posted August 24, 2008 Report Share Posted August 24, 2008 I'll use two words two answer your question: [b]ceteris paribus[/b] In other words, shift one at a time. Reply Link to post Share on other sites More sharing options...
moneyfaery Posted August 25, 2008 Report Share Posted August 25, 2008 [quote name='heartarcade' post='22521' date='Aug 23 2008, 07:56 PM']but in the example commentary they moved them both.[/quote] It might have been a case of combining graphs. I personally had graphs where both D and S shifted, but that was so that the overall presentation of the commentary was better. Reply Link to post Share on other sites More sharing options...
