Help me with demand-supply :(

<< < (2/2)

Collin Li:
Yes, unless there were two exogenous changes (shifts) specified.

Often you are asked to analyse the effect of something, involving a shift in one of the curves. The final equilibrium relies on the dynamics of the supply-demand curve, but it does not shift the other curve. It is just a movement along the other (and this is the dynamics of supply and demand).

costargh:
Fuck, thank-you man. You made everything make more sense now!!!
I'd always had trouble understanding the difference between a shift and a movement of/along a curve.

That totally makes sense now. I always understood what effect business confidence would have on demand, but I interpreted it also to mean an increase in supply, which I can see now why it is not the case.

Will + karma after 12 hour limit is up.
BEST HELP I'VE EVER GOTTEN ON HERE!   

Fyrefly:

Wow.

Go Coblin.

But... Yr 12 economics must b sooo different 2 uni stuff.
We covered movements and shifts of demand and supply in our 1st lecture <.<

If it makes it any easier Costa:
Movements along a curve are a result of a change in P or Q (Change in Q Demanded/Supplied).
Shifts are generally the result of everything else - factors that have changed *other* than a simple change in P or Q (Change in Demand/Supply)
(something other than suppliers/demanders simply saying "ok, we're gonna buy more/sell less/charge more/etc").
Remember tho, that, say, a movement along D occurs when a shift of S occurs, unless the same factor alters both D and S (assuming a free market when S-ers and D-ers r free 2 meet @ a new equilibrium). Same goes for visa versa.

Hope I haven't confused u more, if u don't get wot i've said then dw.
I really have no idea wot's covered in yr 12 eco course or how they explain it.
