Unit 1 Micro: Revision on Elasticity of Demand and Supply

Tuesday, April 08, 2014

Our normal laws of demand suggest that as prices increase demand decreases whilst firms attempt to supply more (with the opposite happening as prices decrease). The concept of elasticity extends this understanding by asking the question ‘by how much does demand and supply change?’

The NHS: Blinded By Love

Thursday, January 02, 2014

The NHS is part of the British establishment just as much as tea, talking about the weather and sarcasm. This view through rose-tinted spectacles has prevented serious debate and clouded our judgment. Foreign visitors are now being charged to use our A & E services, yet they can still see GP's for free. This ludicrous half measure is just one example that we are blinded by love for our NHS. A situation has arisen in which any attempt from politicians to discuss much needed improvements for the current healthcare system is political suicide. This is hindering development.

Unit 1 Micro: Chinese Get into a Froth over Starbucks Prices

Tuesday, October 22, 2013

Where would you expect a Starbucks latte to be cheaper - in a coffee store in downtown New York or in a Starbucks store in China? Keep in mind that per capita incomes in China are around one tenth of those in the United States.

The answer may come as something of a surprise!

In a report on coffee prices that has caused something of a stir across social media platforms, the state-owned broadcaster CCTV reported that a medium-sized latte cost Rmb27 ($4.43) in China compared with Rmb19.98 in Chicago, Rmb14.6 in Mumbai and Rmb24.25 in London.

Starbucks responded that its pricing strategy was based on local market costs, including infrastructure investment, real estate and labour costs. It also added that its Asia-Pacific profit margin was for 14 countries, not just China. They added that each Starbucks market is unique and has different operating costs and that it would be inaccurate to draw conclusions about one market based on the prices in a different market.

The prices of imported goods in China are often raised because of the effects of import taxes (tariffs) - in this case the customs duty on roasted coffee beans is 15%. Add to that a sales tax of 17%.

Price Maximum Example - Milliband’s Domestic Fuel Cap

Sunday, September 29, 2013

Ed Milliband’s conference speech last week gave us one of those all-too-rare moments where we can illustrate a real (or potential) government policy with a standard economic diagram.

Mr Milliband clearly stated that, should the Labour Party win the next General Election (in 2015) they will cap the price of domestic fuel. His policy is aimed at restricting how much people would have to spend on energy so as to improve their general purchasing power as well as reducing business costs. The big losers would be the energy companies themselves who do not seem particularly keen on the policy. Mr Milliband argued that their profits were sufficiently high and, besides, they have been using the lack of competition within the market place to bolster their coffers.

Assuming that teachers have already covered the basics in Demand and Supply diagrams, this link will take you to a short (up to 10 minute) activity asking students to draw the ‘Price-Cap’ diagram and consider the economic arguments for and against the policy proposal.

Manchester’s biggest tourist attraction to close?

Wednesday, June 05, 2013

This morning's news stories include an implied threat to close MOSI (The Museum of Science and Industry) in Manchester, in order to keep the Science Museum in London open.

Should museums charge admissions fees or not? Is a museum a merit good or not? If entry is free, are you tempted to avoid placing money in the transparent collection box as you go in? If is free, how should the museum fund its activities - encouraging donations, marketing guidebooks, souvenirs, themed gifts, or reliance on government grants? This begs questions about how a government allocates scarce funds? 

Florence's Uffizi Gallery does not charge children or pensioners, amongst others. Can you identify which museums have more price inelastic demand, and face a smaller drop in visitor numbers should charging be reintroduced? Why would visitors pay €18 to climb Pisa's famous leaning tower?

Bear in mind that AQA had set a question on this topic in 2004. "Using the data and your economic knowledge, assess the case for and against providing free entry to museums."

MOSI is supposed to be one of Manchester's biggest visitor attractions, but would there be a negative multiplier effect if it closed? Should the cultural heritage be preserved? This clip from Yes Minister helps focus a debate.

econoMAX - Will a minimum price for alcohol work?

Saturday, January 19, 2013

Bill Morrison examines whether proposals for a minimum price for alcohol will work in the UK. The UK Government is looking to introduce a minimum price per unit for alcoholic drinks. The price muted is 45p which would make a relatively strong can of lager approximately £0.95. Currently a local supermarket is retailing a brand of lager containing 2.1 units per can at the equivalent of £0.75. Under the new legislation, should it come into force, the equivalent box of ten cans would have to be sold at a minimum of £9.46. More of which later. However, why do we need to introduce a minimum price for alcohol?

Chocolate Passion - Grown in St Lucia, Made in Cambridge

Friday, November 09, 2012

Angus Thirwell the co-founder and CEO of Hotel Chocolat is immensely grateful to Joanne Harris and Juliet Binoche. respectively the author and star of the hit film Hotel Chocolat. The movie educated a generation of aspirational chocolate lovers in how to pronounce Hotel Chocolat and has helped millions of consumers in Britain and around the world advocate the hit chocolate retail brand without committing a pronunication faux-pas! I wonder how many satisfied customers realise that Hotel Chocolat does not exist? Perhaps they have typed the name into Trip Advisor hoping for a review of a retreat flowing with rather wonderful chocolate made from a St Lucian plantation?

Unit 3 Micro: The Rise of Dynamic Ticket Pricing in Sport

Saturday, October 20, 2012
An autumnal hat tip to Ralph Bostock at the Royal Grammar School Clitheroe for spotting this excellent article from BBC news on the growing use of dynamic ticket pricing by professionals sports clubs. Dynamic pricing to increase revenue - also known as yield management - has long been a common feature of pricing strategies among airlines and bus, coach and train operating companies. Now we find it occurring more frequently for tickets to football clubs many of whom have been struggling to fill their grounds on match day. The Football League has regulations governing ticket prices but Derby County has been given the go-ahead for a trial of dynamic pricing - is it working to boost the gate?
Here is the link to the article

Unit 1 Micro: Prices in Action - Ticket Pricing at Derby County

Monday, September 17, 2012

A warm hat tip to Ed Marsh, Head of Economics at Glyn School for spotting this superb example of a sports club using dynamic pricing technology to determine the prices of tickets for their home games. 

The BBC news site reports  that Derby County are introducing "demand-based" ticketing for the coming season with prices fluctuating according to the opposition, the team's form, kick-off times and even the weather. The system is known as Sports and Entertainment Analytical Ticketing System (SEATS) 

Buy in advance and fans will get cheaper prices - but what if a sizeable group decides to start a game of chicken with the club and hold back from buying? As match day gets closer, ticket prices should move higher, but if demand for a game is well below the stadium's capacity will prices drop back?

Hardened cynics might also point out that the Derby County ground has a fundamental design flaw .... the seats face the pitch!

Petrol, tax, and the downward sloping demand curve.

Tuesday, January 17, 2012

Nearly every country has a tax on petrol, although the amount varies widely. And given that the landed price of petrol is quite similar (see the graph below), it can be seen what effect the tax has on quantity demanded. The results are very much in line what economic theory would predict and there are also clear implications for countries that want to reduce petrol consumption.

Government Plans to boost the Housing Market

Monday, November 21, 2011

The Government has announced today a scheme to help first time buyers on to the property ladder. It has been reported widely in the press with mixed reactions. The BBC article outlines the main proposals (here is the link to The Daily Telegraph). It is interesting from a political point of view that this government should chose to intervene in this market, though perhaps we should not be too surprised as it was the Conservatives that brought in the ‘Right to Buy’ legislation in 1980.

From Harrods to Poundland…

Monday, October 17, 2011

Here is a nice example to illustrate the varying effects of the recession on the economy… A growing influx of high-spending foreign tourists powered Harrods through the £1bn sales barrier for the first time… whilst Poundland has also has reported a 26 per cent boost in revenues to £642m. A good example to use in discussion of goods and services that have different income elasticities of demand. Read the article at the FT here.

The Market for Potash

Saturday, October 30, 2010

This is a superb BBC news report on the rising demand for and prices of potash.

Potash is shorthand for potassium carbonate - a potassium compound often used in agriculture and industry. Potash is the third major plant and crop nutrient after nitrogen and phosphate and the vast majority of the annual global supply is used as a soil fertilizer.  It is a product with virtually no close substitute making the demand insensitive to the ruling market price - the price elasticity of demand for potash is very low and high prices make the product hugely profitable to supply

Price mechanism in action - student car insurance

Saturday, October 16, 2010

Here’s a great example of the price mechanism in action - on a topic that should be highly relevant to many A Level Economists.  As our accompanying chart shows, the cost of buying car insurance(as measured by the retail price index) has risen by a staggering 40% in the last year, with even bigger increases being registered for young drivers wishing to insure their own car or be added to their parent’s policy. 

This BBC video shows one such customer whose pride and joy (a Ford Fiesta) cost him just £700, but whose annual insurance premium is over £2,000.  Suppliers are raising their prices and (in some cases) withdrawing from the market altogether for this “risky” group of customers.  A great way for a lesson to combine supply and demand curves with some citizenship advice too smile

One aspect of the rising cost of car insurance is an increase in the number of uninsured drivers on the roads - higher premiums have made insurance unaffordable for many and some choose to take the risk of failing to insure their car. But accidents involving uninsured drivers has the follow-on effect of increasing the premiums that law-abiding motorists end up paying - a negative externality.

Lifting the cap on tuition fees - a question of price elasticity?

Monday, October 11, 2010

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.
University course fee increases ‘could deter students’ (BBC news)

Let’s hear it for the girls!

Thursday, October 07, 2010

My better half and I recently popped along to the cinema to see ‘Made in Dagenham’.

The film is set in the late 1960s and depicts the true story of the 200 female machinists and their fight for fair pay at the Ford plant in Dagenham, Essex in the late 1960s. The film is an archetypal feel-good piece of social history, and packed with interesting Economics. Teaching to the syllabus alas does not always afford us the luxury of discussing relatively recent Economic history – this is a real shame. An appreciation of these events I feel can really help to bring several topics alive. Encourage your students to go and see the film – it’s all there:

1/ Monopsony – In the late 1960s Ford employed 55,000 people in Dagenham – 54,800 of them were men
2/ Trade Unions and the Supply Side – wage negotiation and industrial action
3/ Legislation – The dispute was a catalyst for what became the 1970 Equal Pay Act: something that still provokes controversy; today – 40 years later – pay disparity still remains an issue (always extra fun to discuss this in an all boys’ school!)

Cinemas are also of course excellent places in and of themselves as regards turning the restless mind to Economics issues. This particular establishment provides sofas for customers to lounge upon, and one is able to order items from the menu via a handy waiter/waitress service. This of course has several ramifications re the business model the firm operates. I marvelled at the application of cross price elasticity as I took in the outrageous prices on the menu! My thoughts turned to price discrimination as I pondered the ticket price! I glanced round approvingly at the civilised audience, gathered together in part via the power of the price mechanism!

I can’t finish without mentioning the fact that the soundtrack during an advert for a well known brand of Corn Flakes was provided by one of my favourite bands … Primal Scream, a Scottish alternative rock group. I almost choked on my Sauvignon Blanc as I vacillated between thoughts of ‘sell out!’ and the use of multiple revenue streams to maximise the value of a well-known product. I have to tell you – the irrationality of the fan won the day …. Oh Bobby, how could you?

 

Next Generation Laptops - An Inferior Good

Wednesday, October 06, 2010

Rory Cellan-Jones, the BBC’s Technology Correspondent, does a pretty spectacular demolition job on an attempt by clothing retailer Next to break into the fast-growing market for tablet devices. A very funny piece to camera that manages to highlight when cheap truly means awful! A lovely clip to show when discussing the nature of inferior products in a given market space.

From heart transplants to watermelons - elasticity of demand

Tuesday, October 05, 2010

Here is a super blog by Jason Welker on aspects of price elasticity of demand - offering some great examples of where demand is either likely to be highly elastic to where consumers are almost immune to changes in the market price.

Scotland nudges towards minimum alcohol price

Friday, September 03, 2010

Here is a good 5-minute discussion here of the 45p a unit minimum alcohol price proposed in Scotland.

It offers a good application of some of the main AS micro topics - since it is targeting consumers for whom alcohol is a problem, the highly price inelastic demand for alcohol will probably mean the 45p minimum price is not a huge disincentive.

Paradoxically, since minimum prices only work if the free market equilibrium price is currenly below the minimum price, what it may actually cause is a shift towards higher strength alcohols that are already above the 45p a unit! There’s the law of unintended consequences for you!

Profiteering from Icelandic Volcano

Saturday, April 17, 2010

The Times features a very interesting article about the reaction or the percieved reaction of travel companies offering substitute forms of travel in the UK. Is the customer being ripped off? Is this price discrimination at work in the market?

Travel companies have denied profiteering from the volcanic dust cloud as stranded holidaymakers face paying premium fares to get home after the Easter break.

Channel ferry firms and Eurostar trains were fully booked this weekend as the Eyjafjallajökull volcano continued to pump ash into the atmosphere and aircraft were grounded across Northern Europe.

Supermarkets accused of price gouging

Saturday, February 13, 2010

The Guardian today carries a story about alleged price gouging by the supermarkets. Tesco and Asda refute the charge but they are said to have lifted the prices of a number of necessary purchases for many household goods in the lead up to Christmas.

“Both supermarkets, according to Bridgeman, would be able to use their sales data or information from loyalty cards to identify those purchases customers feel they have to make at Christmas and then target these categories for some steep rises “to extract maximum profit” from shoppers who have neither the time nor capacity to go elsewhere. So household cleaning goods, shaving products, toiletries, lightbulbs, batteries, pickles, sauces, herbs and spices typically consumed at Christmas, favourite seasonal drinks, hangover and indigestion pills, and must-have family presents were all categories seeing dramatic hikes on some lines”

Price gouging involves charging more for consumers whose demand is price insensitive, in other words the price elasticity of demand is low. This would allow the retailers to achieve a higher profit margin on their sales as they extract consumer surplus and turn it into extra producer surplus. The accusation is a strong one more so because many thousands of families on lower incomes may have suffered price hikes at a time when budgets are already under enormous pressure from the effects of the recession and rising utility and energy bills.

2009 - a desperately difficult year for airlines

Wednesday, January 27, 2010

This BBC news article highlights some of the key economic challenges facing the global airline industry as we move further in 2010. IATA reports that world airline passenger traffic dropped by 3.5% from a year earlier, while freight traffic fell 10.1% as the downturn hit demand. Losses have mounted and the industry continues to have to weather many uncertainties such as the likely strength of a rebound in global tourism, freight and business travel and the volatility of aviation fuel costs. This in the week when Japanese Airlines filed for bankruptcy. IATA has forecast that airlines will lose $5.6 billion (£3.5 billion) on a net basis this year after losing $11 billion in 2009.
