Aggregate Demand and Aggregate Supply - The AD-AS Model
4 important questions on Aggregate Demand and Aggregate Supply - The AD-AS Model
What is the point at which AD intescts SRAS curves? What is it? By whom is it experienced?
the point at which the quantity of aggregate output supplied is equal to the quantity of aggregate output demanded
by households, businesses, the government, and the rest of the world
When are the 2 only times short run equilibrium aggregate output and short run equilibrium aggregate price level can change?
- short run aggregate output and short run equilibrium aggregate price level can change
- because of shifts in the AD to bring it back to short run equilibrium aggregate output, but cause inflation
- shifts of the SRAS curve , that fixed both short run equilibrium aggregate output and short run equilibrium aggregate price level
Reminder: what are the determinants of demand? And how can they be use here? What are the events that shift demand curve called?
- The change in expectations about income or GDP
- The change in wealth
- the changes in existing stock of physicals capital
- The change or use of fiscal or monetary policy
because the government cannot directly affect the AS, it will try to deal with a recession by influencing the AD so that the economy could go back to equilibrium output.
the events that shift demand curve are called Demand shock

For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
When does a shift of the AD curve to the left occur? And what happens to the SR equilibrium aggregate price level and SR equilibrium aggregate output? In which direction do they both move?
- negative demand shock
- this leads to a lower short run equilibrium aggregate output and short run equilibrium aggregate price level
- demand shocks causes aggregate output and aggregate price level to move in the same direction
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
