what is the meaning of aggregate supply and aggregate demand?

Question

and what factors cause shifts in the curves

Answer 1

the changes of supply and demand over a period of time as a total. So basically aggregate means collectivley the total. And the reasons for changes in either factors could be down to anything depending on what it is your are looking at specifically. Eg mobile phones demands increase because of ease, flexibilty, cost, advertising, fashion etc ... so supply increases

Answer 2

I believe aggregate can mean two things:
1. Solid particles in a mixture (i.e. the stone in a concrete mix).
2. Overall/net (i.e. if I buy 3 apples and sell 5, the aggregate output of apples is 5-3=2).

I think you're looking at the second one in this question. So the aggregate supply of something would be the total supply of something minus the amount which breaks in transit? That's a guess. The aggregate demand would be the amount ordered minus the amount they have excess at the end?

Things which cause shifts in curves: new suppliers coming, old suppliers ceasing, better transportation which doesn't break stuff, time of year would affect demand and supply for some things.

Answer 3

Aggregate means a sum of parts. The shifts occurs simply because of the mean average percentage fluctuations; they are based on the whole being a sum of parts. Therefore it can not be stable causing a shift or multiple shifts.

Answer 4

those are words from macro-economics and verify with the entire composites of provide or call for interior a given section, frequently a political entity or land served by technique of a significant economic organization. They play an element in diverse of the overall differential equations appearing in Keynes's well-known theory.

Answer 5

Final demand and final supply

Answer 6

It's the current rate. Not having enough or having too much of the commodity you're referring to.

Answer 7

total demand & total supply
