A2 Economics: Tutor2u Webinar – Multiplier and Accelerator

April 24, 2015 Leave a comment

Here is an excellent webinar by Geoff Riley of Tutor2u on the multiplier and accelerator. This is part of Unit 5 in the CIE A2 course. Although the examples that he talks about are UK based he explains the theory very well. Worth a look especially with mid year exams approaching.

Sustainable Prosperity – Interview on Radio New Zealand

April 13, 2015 Leave a comment

Radio NZOver the Easter break I heard a very good interview on Kim Hill’s Saturday morning programme. The interview was with Bronwyn Hayward Associate Professor of Politics and head of the Department of Political Science at the University of Canterbury, who will lead one of nine research teams for the new international Centre for the Understanding of Sustainable Prosperity (CUSP).

In short, “Sustainable prosperity” would come as a result of sustainable development that enables all human beings to live with their basic needs met, with their dignity acknowledged, and with abundant opportunity to pursue lives of satisfaction and happiness, all without risk of denying others in the present and the future the ability to do the same. This means not just preventing further degradation of Earth’s systems, but actively restoring those systems to full health. Source: Worldwatch.org

A2 Revision – The Accelerator

March 23, 2015 Leave a comment

The accelerator theory states that investment is determined by the RATE AT WHICH INCOME, AND HENCE OUTPUT, CHANGES OVER TIME. The principle states simply that unless the rate of increase in consumption is maintained, the previous level of investment will not be maintained.

This theory assumes that firms try to maintain some constant relationship between the level of output and the stock of capital required to produce that output. In other words, we assume a constant capital-output ratio which can be expressed in either physical terms or money terms. The accelerator helps us to understand how small changes in demand in one sector can be magnified and spread throughout the economy. The example below assumes that the firm starts with 8 machines each year and 1 machine wears out each year and that each machine can produce 100 units of output per year. In the second year, demand rises for capital goods rises by 200% (from 1 to 3). When the rate of growth of demand for consumer goods slows in year 4, demand for capital goods falls. In year 6 demand drops and they is no requirement for any investment.


Limitations of Accelerator:

* Firms can meet output with stocks – may not need investment
* Changes in technology may mean firms don’t need to invest in as much capital as before
* Firms need to be convinced that demand is long-term to warrant investment
* Limited supply of technology available

Saudi Arabia’s plan to gain market share of oil industry

March 10, 2015 Leave a comment

Oil StocksThe recent drop in oil prices from $115 per barrel in June last year to $58 per barrel today (10th March) has asked the question why don’t oil producers cut back on supply? This would seem to be the logical policy to pursue as the revenue of oil producers has been cut significantly. However Saudi Arabia has allowed big oil surpluses to grow and as a result the price has fallen. As Saudi Arabia can extract the oil from the ground at a much lower cost than its oil producing counterparts they have a greater ability to absorb the lower oil price. Those that have a high cost of extraction – US shale producers, the tarsands of Canada, Russia, Venezuela – are now finding the return from oil is much lower. Therefore, the plan being to force high costs producers out of the market leading to an increase in the market share of the Gulf states.

Excess Oil Supply
There has been a growing amount of oil in storage which is absorbing the glut. World stocks have increased by approximately 265m barrels last year and is suggested to increase by a further 1.6m-1.8m barrels a day in the first six months of 2015 which adds about 300m barrels to the total. Oil producers are hoping that the demand for oil will increase next year and that the accumulated stock will satisfy that demand. However the restocking cannot continue for long as storage facilities in Europe and Asia are already at 80-85% capacity. Companies are going as far as renting oil tankers to store the excess oil. And what happens if storage facilities start to reach full capacity, then producers will be forced to dump supply onto the market dropping the price even further. There is the belief that oil prices will drop in the long run which will mean a restructuring of the industry.

World Dairy Prices and New Zealand Droughts

March 3, 2015 Leave a comment

WDP NZ droughtsHere is an image from the recent Westpac Economic Overview. As New Zealand is the world’s largest exporter of dairy products any disruption in the supply from New Zealand can impact on the global dairy prices. The last few droughts saw world dairy prices increase considerably as milk supply from the rest of the world was unable to adjust to market conditions. However supply capacity in the US and the EU has increased and with Russia’s import ban there is a much greater supply on the global market. Nevertheless, this doesn’t disprove the possibility that prices rise when supply falls short. The overall signs are that supply and demand are coming into line as Chinese buyers run down stocks. The drought in New Zealand will further boost prices from current low levels. Westpac expect the milk price to rise to $6.40/kg for the next season. Below is a useful video clip from Dominick Stephens – Chief Economist at Westpac – about the primary sector in New Zealand. It is very good on fundamentals – supply and demand.

A2 Economics – Keynesians vs Monetarists

Just been going through this part of the course with my A2 class and came across a table from some old A Level notes produced by Russell Tillson (ex Epsom College Economics and Politics Department) to help them understand the principal differences.

German Economy motoring on

February 17, 2015 Leave a comment

With euro area finance ministers meeting to discuss the Greek debt issue there has been positive news with regard to the the overall growth in the euro economy. Driven by consumption (C) and Investment (I) the German economy grew by 0.7% in the Q4 which makes the annual figure 1.4% in 2014 – see graph below. This helped the overall growth rate of the euro zone area 0.3% in Q4. The German figure is surprising when you think of the economic sanctions against Russia which has hit hard the German export market (X) – export volumes contracted 2% in Q4 in 2014. By contrast the DAX (German Stock Market indicator) recorded an all time high of 11,013 and German real wages rose 1.6% which was helped by falling oil prices.

Other euro areas didn’t do as well as their German counterparts but the important fact was that figures were more optimistic and better than expected for Q4 2014:
Slovakia +2.4%.
France +0.1%

Spain +0.7%,
Netherlands +0.5%,
Portugal +0.5%
Italy 0%,
Greece -0.2%.
