Observatory of Economic Complexity (OEC) – great graphics on global trade

I picked up the OEC site from Michael Cameron’s blog ‘Sex, Drugs and Economics’. The Observatory of Economic Complexity is a tool that allows users to quickly compose a visual narrative about countries and the products they exchange. It was Alexander Simoes’ Master Thesis in Media Arts and Sciences at the MIT Media Lab. The project was conducted at The MIT Media Lab Macro Connections group. Alex’s Advisor was César A. Hidalgo, principal investigator of Macro Connections. Since its creation in 2010, the development of The Observatory of Economic Complexity has been supported by The MIT Media Lab consortia for undirected research.

The graphics on each country and products are superb and include:

  • Exports
  • Imports
  • Trade Balance
  • Destinations

It also includes Economic Complexity Index which measures the knowledge intensity of an economy by considering the knowledge intensity of the products it exports. Below are some images on New Zealand trade.

AS & A2 Revision – How PED varies along a demand curve

Been doing some more revision sessions on CIE AS economics and went through how the elasticity of demand varies along a demand curve. Notice in Case A that the fall in price from Pa to Pb causes the the total revenue to increase therefore it is elastic – the blue area (-) is less than the orange area (+). In Case B the opposite applies – as the price decreases from Pa to Pb the total revenue decreases therefore it is inelastic – the blue area (-) is greater than the orange area (+). In Case C the drop in price causes the same proportionate change in quantity demanded, therefore there is no change in total revenue – it is unitary elasticity. Remember where MR = 0 – PED = 1 on the demand curve (AR curve).

Using whiteboards to teach externalities

In my teaching I am very keen on using whiteboards so that students can get used to drawing graphs and also writing essay plans. It makes it very easy for me to go around the classroom to check on their accuracy and I have to say that the students enjoy the whiteboards even if it does lead to a little doodling. The boards are just over A3 size and are perfect to draw some of the more complex graphs in NCEA and CIE economics. Below are some externality graphs by A2 student Jonathan Ta.

A2 Worksheets – Perfect and Imperfect Labour Market

Currently covering Labour Markets with my A2 level classes and put together an exercise which tests them on calculating MCL, MRPL etc and also showing why MCL = MRPL is the number of workers a firm should employ. There is an exercise for both Perfect and Imperfect Labour markets – see ‘Word’ document. The excel document is a model answer showing the data in a table and a graphical format. Hope it is of use.

Great economics revision videos from Tutor2u

Here is a great set of revision videos by Geoff Riley of Tutor2u. They cover a range of macro and micro topics for AS and A2 Level economics. Most of them are around 8 minutes long and he uses the powerpoint slides very effectively so you get his oral contribution plus the key points on the presentation slides. Well worth a look and you are bound to find them very useful as exams approach. Below is the video on the Circular Flow.

 

 

 

Inflation – Hungary 1941 – House and Jelly Bean

Here is a very useful video on Inflation from The School of Life. It discusses the causes of inflation and why it is seen as big problem in countries. They use the example of Hungary in 1941 and explain how inflation erodes the purchasing power of the income of citizens – a good example of a house and a jelly bean. Mention of Keynesian and Monetarist schools of thought – useful for IGCSE courses and above

Skyscraper completion = Economic Downturn

Barclays Capital have produced an interesting indicator in that its Skyscraper Index shows the relationship between construction of the next world’s tallest building and an imminent financial crisis.

Over the past 140 years it is interesting to see the economic environment post skyscraper completion. The Great Depression was matched by 3 record breaking New York skyscrapers. With the completion of the World Trade Center skyscrappers in 1973/4 saw the looming spectre of stagflation (high unemployment and high inflation) in both the US and UK economies. This condition was further compounded by the breakdown of the Bretton Woods Agreement.

The Petronas building in KL was followed by the Asian currency crisis and the Taipei 101 coincided with the early 2000’s recession and the end of the technology bubble. The Burj Khalifa was completed in 2010 which was amidst the current financial crisis. Its increase in height over the previous highest skyscraper is indicative of the extent of the current economic crisis.

WE THE ECONOMY – 20 short movies on economics

WE THE ECONOMY website provides a series of short films that explain economic concepts or key features of the modern economy. Each of the 20 movies focuses on some aspect of the U.S. economy or on some economic concept. The films are grouped into five ‘chapters’ covering the basics of the economy:

What is the Economy?
What is Money?
What is the Role of our Government in the Economy?
What is Globalization?
What Causes Inequality?

Every 5-8 minute video is well worth watching and useful for the classroom. Below is the trailer – very professionally done and excellent reinforcement when teaching certain topics.
