Today we'll be solving problem three from chapter 29 of economics 12 edition.
00:05
This problem wants to know what kind of event would cause a demand pull economic inflation.
00:12
So any event that affects aggregate demand can create demand pull inflation if it increases the aggregate demand curve.
00:20
So here are some examples.
00:22
The quantity of money in the economy increases.
00:25
The interest rate decreases.
00:28
Government expenditure increases.
00:31
Government passes a tax cut.
00:35
An economy experiences an increase in exports or an increase in the investments causes an increase in expected future profits.
00:44
So those are just some examples of what might increase aggregate demand and cause demand pull inflation.
00:50
The next part of this question wants you to describe the effects of a demand pull inflation and how it might lead to demand pull inflation spiral.
00:58
So here's the graph that we are given at the beginning of the question.
01:02
And our economy is starting where aggregate demand zero and short run aggregate supply zero meet each other, which is here, and our real gdp is at g0.
01:15
Let's say our economy experiences an increase in exports.
01:20
This is going to cause our aggregate demand curve to shift to the right from aggregate demand zero to aggregate demand one...
