Aggregate Demand Part 1
Nov 1st
Relevant Syllabus Points:
3.3. Macroeconomic Models: Aggregate demand—components
3.4 Demand-side and supply-side policies: Shifts in the aggregate demand curve/demand-side policies [fiscal policy, interest rates as a tool of monetary policy]
Questions:
- What is Aggregate Demand?
- What are the components of Aggregate Demand?
- What shape does the curve have and why? How are the axes labelled?
- What causes a movement along the AD curve?
- What factors affect Aggregate Demand, causing it the curve shift? Categorise your answers under the four main components. Give examples and show the effects in diagrams.
Overview of the Aggregate Demand Curve:
CuteChadz gives a 2 minute overview. Note that figures given are UK based and the 2nd bullet point on Consumption is a bit confusing and so can be ignored:
mjmfoodie on AD and AS. Watch the first 4 minutes (we can use the last 1 and a half minutes later when we cover Aggregate Supply)
Why does the Aggregate Demand Curve slope downwards?
econsteve12 gives quite a thorough and clear explanation here:
Reffonomics on Slope of Aggregate Demand
What factors affect aggregate demand?
CuteChadz gives a 10 minute overview, referring to such things as loose, tight, fiscal, and monetary policy.
Specifically, what influences Consumption, the main component of AD?

All The World’s Flights In A Day
Mar 22nd
This video (of which there are several copies on youtube) could provoke a lot of interesting questions. Where in the world receives the most air traffic? Why? How does this reflect historical developments? Does the spread of daylight hours affect flight concentrations? Which two continents / regions are the most connected by flights? Again, why? How does the perspective of a 2D map affect the apparent speed of flights in different parts of the globe? How else might this data be shown?
Thanks to my colleague Darren for passing this on.
The World’s Most Typical Person
Mar 7th
The world’s most typical person is male and in terms of the mode average ethnic group, is a Chinese, Han man. His age, in terms of median average is 28. The typical face shown above is built of 190 000 photos of 28 year old ethnic Han men. But as the video tells us, he won’t be the most typical person for long …
As World Population approaches 7 billion, NationalGeographic have created a brilliant infographic-style animation, complete with catchy tune and thought-provoking statistics. (There’s also a healthy qualifier in there – “typical is always relative”).
A great starter for population studies or even for discussions about global inequality, like the World Scaled Down to A Village of 100 idea. It might also have value in Theory Of Knowledge discussions of data and what we mean by ‘typical’ and ‘ethnicity’. There’s even a bit relevant to the economic concept of ‘needs and wants’ at the very end.
Packed full of cross-curricular uses, it is simply a ‘must see’.
The World Scaled Down to A Village of 100
Nov 28th
Just came across this video, based on what is now a widely-read summary of some key demographic and economic statistics. These statistics do need to be verified, as the opening shot states, if not for any other reason than the age of the data. This notion of the world as a village of 100 (and the associated data) first emerged in the early 1990s.
As David Truss argues, this could be really useful for cross-curricular discussion. I’ve used the Village of 100 idea a few times – in Geography, Economics and as part of an assembly. I first received an email with this idea in 1998, and used some of it when visiting a Secondary School in southern Ghana in 2003. Teaching a Geography class of nearly 70 students, I tried to apply the same concept for some of the issues covered by asking the appropriate proportion of the class to stand up. The Ghanaian students were blown away by the proportion of their class that would live in Asia (having guessed Africa and Europe to carry the highest populations, by far). The ICT teacher at that school (who commanded a suite of 16 computers for a school of c. 2,500 students) was fascinated by the internet access statistic.
For another way of visualising global economic inequality (which features in the Village of 100 idea), I highly recommend this website:
Update:
This impressive and simple website helps you to make quick comparisons between your own country and any other – this can call up statistics that call to mind the inequality depicted in the Village of 100. Watch out for the adverts though:
‘Eat Local ‘ Government Advertising Domestic Produce
Nov 9th
Why would a government encourage consumers to ‘buy local’?
What impact would this have on the demand / supply diagram for these products?
How could this be considered a form of protectionism?
IB Economics: Why might a government introduce this together with certain price controls (such as a minimum price / Buffer stock programme)?
Introducing the Millennium Development Goals
Nov 7th
What are the 8 Millennium Development Goals? This 30 second video introduces them:
This video includes a bit of a speech by Kofi Annan who was Secretary-General for the United Nations when the Millennium Development Goals which were agreed in 2000 at an important meeting (The Millennium Summit) where a number of world leaders discussed ways to reduce poverty in the world. The images and facts help explain his message:
Another good video to introduce the MDGs:
These slideshows also help explain the 8 Millennium Development Goals:

Millennium Development Goal 3
Nov 7th
Watch this video about Millennium Development Goal 3:
These two videos are part of a series by planinternationaltv called ‘Because I am A Girl’ and they tell us about some important facts (statistics) about girls around the world:
A similar video by PlanUSAvideos makes us think by comparing the birthdays of girls in very poor countries to some typical birthdays of girls in USA:

A Song about Elasticity
Oct 28th
Some people have a lot of time on their hands, but we should sometimes be grateful for that … this song summing up the different elasticities is worth a listen (you never know, it might even help you revise this particular topic …)
The new ‘Think You Know’ Video?
Sep 12th
Following a theme introduced by Karl Fisch’s Think You Know video, this video produced by the New Brunswick Department of Education on 21st Century Education is professionally made, eye-catching stuff. According to the blurb on You Tube:
This video was produced by the New Brunswick Department of Education to stimulate discussion among educators and other stakeholders in public education in the province of New Brunswick. The 21st Century presents unique challenges for education worldwide. In order to keep pace with global change we must focus on 21st Century Skills and public education must adapt to keep students engaged
