Supply Revisited
Oct 25th
This post is to add further resources on the concept of supply, for those who wish to follow up on this absolutely essential concept in Economics. First, however, I recommend you use the resources on this post to learn about supply: http://opengecko.com/economics/supply/

Change in supply / change in quantity supplied by vaacon1
Various factors (short clips) affecting supply by vaacon1:
The diagrams are quite hard to see on the whiteboard, but the explanations and examples are clear.
Supply shifts – Prices of Relevant Resources
Supply Shifts – Expectations of Future price
Supply Shifts – Number of Sellers
Supply Shifts – Technology
Supply shifts – Taxes and Subsidies
You will need to revise what taxes and subsidies are.
Supply shifts – Government Restrictions

Note – at one point she claims the market is the whole planet’s population, but we can talk about more specific, smaller markets than that. E.g. the market for cars in Thailand.

The diagrams are quite hard to see on the whiteboard, but the explanations and examples are clear.
Demand shifts – prices of related goods
Demand shifts – expectations of future prices
Demand shifts – Income
Demand shifts – Number of buyers
Demand shifts – Preferences
As he adds, in text, part way in, he makes a mistake early on and mentions shifts in supply, when he is actually discussing shifts in demand.

Before starting to understand Price Elasticity of Supply, it is worth recapping Price Elasticity of Demand. Click on the following link:
www.business2000.ie provides an interactive quiz on PED
This site introduces the main concepts of Price Elasticity of Supply:
Slideshow from http://www.econ.ucsb.edu
This site gives a useful overview of PES:
This web page details price elasticity of supply, but is a little complicated:
http://dotlearn.com/topics/Economics/1040/content/
This web page provides information on how time effects PES:
This site gives a useful interactive demonstration of PES calculations:

This video from pajholden helps understand the concept further (note, this is suited to A Level / IB students):
Finally, if you think you’ve made yourself an expert in PES, you can test your understanding using the following quiz:
Market Failure
Nov 27th
These YouTube clips help us to understand some of the ideas to do with Market Failure. Some of the ideas in the first clip are not needed for IGCSE understanding (adverse selection and moral panic).
1) General understanding of Market Failure
2) Negative Externalities Explained
Note this uses Marginal Costs and Marginal Benefits curves. Marginal Benefits is the same as the Demand Curve. Marginal Costs is the same as the Supply Curve.
3) Public Goods
