Improving Evaluation Skills in Economics Exams
Here is an updated version of the WEESTEPS approach to economics evaluation designed to boost the evaluation scores and exam results for AS and A2 students. Paul Bridges is the mastermind behind this superb approach to evaluation - it gives you some great pointers about the evaluative approaches that can be used. Works well for micro and macro - but particularly when you have to evaluate a specific policy intervention in a market / industry / or a macro policy discussion.

The price of carbon emissions permits inside the EU’s emissions trading system has fallen to a record low. A sharp fall in total CO2 emissions in Europe has been the driving factor behind the fall in the carbon price. Last year Germany’s CO2 emissions fell by 1.2% and the UK saw a 7.2% reduction. The overall decline in the 27 country ETS was 2.4% in 2011 causing the carbon price to drop below 7 Euros per tonne.

The housing sectors of many towns and cities around the world have often been the target for different forms of government intervention including planning regulations, subsidies and direct price controls.
Price controls are legal restrictions on how high or low a market price may go. They can take two forms: a price ceiling, a maximum that price sellers are allowed to charge for a good, or a price floor, a minimum price buyers are required to pay for a good.
Our focus in this blog is the decision by the authorities in New York to extend arrangement for rent controls for a million rent-regulated units in the Big Apple. This provides an opportunity to look at the basic supply and demand analysis for housing rent controls and build a critical evaluation of some of their effects.

For several years the European Union Competition Commission has been targeting the oligopolistic mobile phone industry accusing it of damaging consumer welfare with high roaming charges when people are travelling and working within Europe. Yesterday marked another landmark in the battle between the regulators and the industry.

Around this time of my micro course my students look at maximum prices (price ceilings) in different markets. There are still plenty of contemporary examples to consider, for example salary caps for executives, caps on the cost of mobile phone texts and roaming charges, rent ceilings etc. But here is a resource that will be of special interest to football-loving economists, namely the 50th anniversary of the ending of the maximum wage in football. The Independent has this nifty set of graphics looking at landmarks in wages of top footballers over the years. Click on: The maximum wage and football’s money trail
Competition Plan for Universities
So the Universities White Paper has been published. Words like “Competition” on news feeds instantly make me sit up and take notice. As my Year 12s embark on their odyssey into market structures and ever more close encounters with efficiency, I think this might just be the case study of the moment. After all its subject matter is foremost in many of their minds.

The financialisation of the British economy continues apace. This article in the Guardian reports that US pay day loan businesses (regulated loan sharks to you and me) are planning a rapid and sizeable entry into the UK consumer credit market. In part this might be because in the UK there is little or no effective regulation on what they can charge.
Cash-strapped families often denied credit by high street banks are vulnerable to the heavy marketing of these businesses - students will know of one of them Wonga the shirt sponsor for Blackpool FC. The typical pay day loan is around £75 to £750, which is deposited in their bank account in as little as 15 minutes, to be repaid in around two to four weeks but with interest rates that can easily reach 30% a month or higher.
The pay day loan market might be a good case study for students wanting to understand more about the demand for credit and discussions about whether there should be a maximum price or cap on the interest rates that can be charged.
Watch out for the £7 chocolate bar!
Will a collapse in global cocoa production bring an end to chocolate as an affordable treat and giver of blood sugar? This article from the Independent today was timely as I am teaching price volatility in commodity markets in my AS micro class as a prelude to discussions abour price intervention strategies such as maximum prices / buffer stock schemes etc. I have attached my class homework as a word file in case it is of use to colleagues.

Here is a highly relevant section from a new report from Commodities Now
“World food prices have been trending higher as emerging markets have increased their share of global food demand due to rising populations and incomes. Food products are having to compete for finite resources such as water, land and fertiliser inputs and are increasingly being used for alternative applications such as bio-fuels. As an example, ethanol now accounts for approximately one-third of annual corn output in the US, up from 5% a decade ago.”

Lifting the cap on tuition fees - a question of price elasticity?
The latest review of university funding has recommended that the cap on tuition fees be lifted giving universities more freedom to raise annual tuition costs well above the current level of £3,290 a year.
To what extent will a rise in the private cost of studying for a degree lead to a substantial fall in market demand from UK-based students? This BBC news feature makes for interesting reading and links in well to the concept of price elasticity of demand - the responsiveness of demand to a change in the market price. There is little doubt that the cost of taking a university education will rise substantially in the years ahead and this raises hugely important questions about the impact on demand and the effect on students from poorer backgrounds who might be priced out of a degree.
It seems that Business Secretary Vince Cable has already come out against introducing a Graduate Tax - one of the main alternatives to raising tuition fees. The issue is debated here in this discussion on the Radio 4 Today programme. There is more background on the university funding issue here.
Further articles on the economics of a graduate tax can be found here.

Unit 3 Micro: Efficiency and Price Intervention in Markets
In recent times the European Union Competition Commission introduced maximum prices for the roaming charges made by mobile phone service providers. These are the rates charged by one operator to another to enable its customers to make calls while visiting another country.

From July 2010 the EU is introducing price caps on the roaming charges facing users of mobile / smart phones but beyond the boundaries of the EU in countries such as Turkey, New Zealand and the United States there are dangers that smart phone users might face horrendously expensive bills - a 10 minute video downloaded with five music tracks could cost £200! A simple email with an attachment could cost £8. Is there any way that price caps could be extended? Or are users simply suffering from information failure by not understanding how to disable the roaming facility? This BBC video provides a timely reminder of the risks.
Price elasticity of demand for stamps
The BBC reports that PostComm - the postal service industry regulator has given initial backing for Royal Mail to increase the cost of a standard first-class stamp by three pence. This would take the price up to 42p. At the same time, standard second-class stamps may rise by 2p to 32p. How will consumers respond to the price change? For many the price hike will have little effect - most of the stamps that I buy can be reclaimed as stationery expenses. But many smaller businesses spend heavily on mailshots as a part of their marketing. A rise in mail costs may cause them to consider making more effective use of their customer databases so that - for example - a 3000 mail shot volume is better targeted than before. Do you think that the price elasticity of demand for stamps is price inelastic - at least in the short term?
The Royal Mail is subject to a price cap agreed with their industry regulator. Since the Royal Mail?s current price control was agreed in 2006, the Royal Mail has lost 9% of its mail volumes over the three year period to April 2009, largely through shrinkage of the total market including 20% of stamped mail. The Royal Mail has also had to face up to increased competition as the postal market has been fully opened up to competition.
Shrinking mail volumes has the effect of reducing capacity utilisation of their collection, sorting and delivery capacity and leads to a rise in the unit costs of the business. The Royal Mail is required by law to operate a universal service across the UK; it is a business that requires substantial economies of scale to remain profitable.
OFWAT wants cuts in the real cost of water bills

The water regulator OFWAT has published their latest five-year price capping proposals for the UK water industry. They want household bills to fall in real terms for water customers in England and Wales - positive news for people struggling to pay their utility bills but not so for shareholders in the water companies who have become renowned for their generous dividends on the back of price increases over and above inflation in past years.
