Hello, so today i'm going to answer a question about the specific effect of three situations or events in the demand curve.
00:11
For doing so, i'm going to use a graphical representation.
00:14
So this is the supply and demand curve.
00:16
In the article, access you will have the prices and in the horizontal axis you will have the quantities in the specific case of donuts.
00:23
This positive line is the supply relationship and this one is the amount curve.
00:28
So the first question is what happened if there is a change in the expectation of the future income.
00:32
So in this case, clear that it will be achieved, but we can say where it will be achieved, up or down, because we don't know what is the expectation if they increase or not.
00:43
If the price of the dough not decrease, it will be the case that the supply move to here.
00:51
It will make that there is a movement of the demand along the curve.
00:55
The final one is that they decrease the number of the consumers.
00:58
So in this case, they will generate a change like this one...
