Unit 3: Ofwat curbs price rises

Here is an important example of regulatory control of utility businesses with regional natural monopoly power. Ofwat is requiring regional water companies to cut their bills in real terms for the next five year pricing regime.

Regulatory agencies are often accused of failing to be sufficient strong with suppliers leading to allegations of regulatory capture i.e. producer interests dominate consumer interests. Ofwat may be an example of a regulator that avoids this criticism.

Questions for discussion:

Why does the water industry need regulation?
Are there any disadvantages to the consumer of govt intervention?

Unit 1: Cost benefit analysis and Swansea Bay

Plans for the Swansea Bay tidal lagoon power station are potentially a superb case study to use when teaching the multiplier effect, renewable energy, cost-benefit analysis, economies of scale and different forms of government intervention including subsidies for harnessing new energy sources.
According to an article in the Independent:

"The £850m, six-mile-long U-shaped seawall by the Swansea docks will not only generate enough electricity to power 120,000 homes for 120 years – it will also create nearly 2,000 construction jobs in the two years it takes to build; and it will leave the city with a tourist attraction drawing in up to 100,000 visitors a year."

Unit 1: Monetary policy - Factors affecting Interest rate decisions

Click here for a really informative piece from Larry Elliott at the Guardian on some of the factors that the Bank of England will take into account when deciding the moment to move policy interest rates up from their historic low of 0.5%. 
Mark Carney in thoughtful mood!

To think, there are students who might make it through their entire secondary school education without experiencing a change in UK monetary policy interest rates!

Unit 3: Supermarket Price Wars

Morrisons has announced further price cuts in its latest effort to win back customers and revive its business.
It is the latest round in a price war among British supermarkets, which are reacting to the challenge of discounters such as Aldi and Lidl.  Click here to access full article.

Really good example of how oligopolies will still use price as a competitive strategy, even though it is likely to harm profits in the short run.

Unit 4: Introduction to inequality

Income distribution (often overlooked, especially when economies are booming) seems the hottest topic at the moment. Inequality books top the bestseller lists.

There are some excellent resources at the end of this post (Thank you Tom White). If you manage to look at some of these over the break, you will have an excellent understanding of this popular area of the course.

Inequality as a topic is great for macro, with scope for analysis and evaluation of UK government policy and approaches to development economics.

Things you need to understand include:
  1. Looking at and measuring poverty – what’s happening to absolute and relative poverty around the world?
  2. Why is absolute poverty falling? Where is it falling fastest? Where is it still entrenched?
  3. What do Lorenz curves look like, and how is the Gini co-efficient calculated? Clarify the distinction between income and wealth.
  4. Is relative poverty a crucial component in a successful and dynamic economy?
  5. “The rich get richer and the poor get poorer”. Discuss.
  6. Does inequality hamper growth and poison human development?
  7. Is inequality a price worth paying if it is accompanied by rapid growth and living standards?
  8. How can inequality be expressed other than by income?
Extension activities

  1. What theories are presented for rising levels of inequality within many economies?
  2. Evaluate policies that could reduce inequality (a) within economies (b) between economies.

Unit 4: The UK Productivity Gap

Measures of productivity, essentially the quantity of goods and services produced per worker or per hour, can be used to inform estimates of an economy's ability to grow without generating too much inflation. It seems that the UK is 16% below productivity levels pre-crisis. This is not good for growth and competitiveness!
