Test your Knowldge on A2 Diagrams (Day Three)

Wednesday, April 16, 2014

Today is the final day of posting resources aimed at testing knowledge on diagrams (please see the links at the bottom of this page for easy access to Monday and Tuesday's blog posts).  The resources are aimed at testing knowledge on some of the key diagrams that students need to know for their exams.

Today's diagrams are for A2 students in both micro and macro economics.  We're sorry, but the diagrams are primarily aimed at students undertaking the AQA version of the Economics qualification.

For both micro and macro, you have a Powerpoint file that can be used in class to test knowledge using a scrolling slideshow.  There is also a static diagram file for both topics that can be used in class or as a revision tool for students.

Labour Market: UK Minimum Wage does not Cost Jobs

Tuesday, April 08, 2014

The introduction of a national minimum wage does not lead to job losses. That is the central finding of research by Peter Dolton and
Michael Stops, to be presented at the Royal Economic Society’s 2014 conference.

Normative statements - using E-Cigarette newspaper reports to look at normative statements

Friday, April 04, 2014

I'm sure that introducing the concept of normative statements is something that most Economics' teachers introduce early in the curriculum to show the dangers of expressing opinions without evidence.  It's a tricky balancing act that we have to play - as students start to write longer, evaluative pieces we are keen for them to make reasoned arguments that don't sit on the fence but warn them of the dangers of starting to rant.

I thought that the two reports included on the document here might prove an interesting activity.  The file contains two reports into a possible plan from the Welsh Assembly to introduce a ban on the smoking of E-cigarettes in public places (akin to the current ban on smoking of 'traditional' cigarettes) in Wales.  The articles are interesting in their own right in explaining the reasons behind such a plan and as an example of Government intervention to solve a possible market failure (although one of the articles clearly identifies E Cigarettes as a solution to a market failure itself).

You could also ask students to read through the two articles and answer the following questions:

  1. Which of the two articles appears to offer more opinion-based evidence than the other?
  2. Highlight any words or phrases that indicate a value judgement rather than evidence-based reporting.
  3. Based upon your own reading and picking up on journalistic styles, have a guess which newspaper each article was published in.

The answer to this final question is in the 'read more...' section of this blog.

Unit 3 Micro: Energy firms face competition inquiry

Friday, March 28, 2014

The big six energy firms in the UK - who account for more than ninety per cent of suppliers to UK household, commercial and industrial consumers - will be subject to another investigation by the competition authorities.  

A report by regulator Ofgem has called for an investigation by the Competition and Markets Authority (CMA) which could take nearly two years to complete - effectively pushing the issue into the long grass well beyond the date of the next election.

Unit 3 Micro: Pop Up Shops on the Underground

Saturday, March 15, 2014

In recent times, pop up shops (retail outlets available on very short term leases) have grown in popularity. In part this has been because of the increase in vacant retail space during and in the aftermath of the last recession. But increasingly other organisation are thinking about using their locations as opportunities to attract small retailers and/or retail start-ups. 

Transport for London is one such example. TfL owns more than 1,000 retail properties and this week TFL has signed a deal with Appear Here, an ‘online property agency’, to allow pop-up shops and restaurants in its tube stations. Consider the business potential for this kind of retail investment. Old Street is earmarked for this experiment - it is just a short walk from Silicon Roundabout in Shoreditch - the home of hundreds of emerging tech start up businesses.

Price Regulation in Industries

Wednesday, March 05, 2014

Regulation of prices through price capping has been a feature of regulation of the utilities in the UK for many years – although this is now being phased out as most utility markets have become more competitive.

Price capping systems

  • Price capping is an alternative to rate-of-return regulation, in which utility businesses are allowed to achieve a given rate of return (or rate of profit) on capital.
  • In the UK, price capping has been known as "RPI-X". This takes the rate of inflation, measured by the Consumer Price Index and subtracts expected efficiency savings X. So for example, if inflation is 5% and X is 3% then an industry can raise their prices on average by only 2% per year
  • In the water industry, the formula is "RPI - X + K", where K is based on capital investment requirements designed to improve water quality and meet EU water quality standards. This has meant increases in the real cost of water bills for millions of households in the UK.

Advantages

Capping is an appropriate way to curtail the monopoly power of “natural monopolies” – preventing them from making excessive profits at the expense of consumers

Cuts in the real price levels are good for household and industrial consumers (leading to an increase in consumer surplus and higher real living standards in the long run).

Price capping helps to stimulate improvements in productive efficiency because lower costs are needed to increase a producer’s profits.

  • The price capping system is a tool for controlling consumer price inflation in the UK.

Disadvantages

Price caps have led to large numbers of job losses in the utility industries

Setting different price capping regimes for each industry distorts the price mechanism

Unit 3 Micro: Facebook Buys WhatsApp

Friday, February 21, 2014

In a bold move in the continuing battle between Facebook and Google to dominate the next phase of digital / mobile growth, Mark Zuckerberg's listed business has agreed an £11bn acquisition of WhatsApp - a deal to be paid in a combination of cash and shares.

The total value of the deal is staggering high for a business that employs just over 50 people.

  • The price Facebook is paying for WhatsApp is more than ten times what Google spent on YouTube
  • It is more than 20 times what Facebook paid for Instagram
  • The $19bn paid for WhatsApp works out at $40 for each of its 450m users!
  • The $19bn deal to buy WhatsApp is more than 10% of the annual value of Ukranian GDP

What are some of the justifications for such a mega-priced deal?

Government underestimates the amount of student loans that are likely to be paid back

Friday, February 14, 2014

According to a report published by the Parliamentary Public Accounts Committee, the Government are currently underestimating how many students will actually pay back their university loans over the coming decades.  Currently, the Government estimates that between 35 and 40% of loans to Higher Education students are never paid back - the Committee believes that the rate on non-repayment is much higher and reflects a weakness in the loan collection method.  The primary reason for non-repayment is that student details get lost over a period of time particularly if the graduate moves and works abroad or was an EU citizen who has returned to their own country.  The method of using the income tax registration process as a way of locating former students has been criticized for not being an effective method of collecting information.  It is estimated that the shortfall could be as much as £80 million by 2042.

Energy companies charge cash-paying customers more - market failure and Government intervention

Tuesday, February 04, 2014

If you attended the recent tutor2u revision conferences for up-coming micro-economic exams (look out for the macro workshops and combined micro and macro to come in March) you will have seen how fuel-pricing was used as an example of market failure, government intervention strategies and government failure.  

Fortunately, the energy market is a gift that keeps giving to us in the economics world (every cloud has a silver lining) as a report out today (see this link for the BBC version of the story) indicates that Parliament is about to intervene to try and stop the energy companies charging more to customers who pay by cash rather than by direct debit (£114 per year, according to the report).

Superbowl Adverts - Has the Viral Video Trumped the Big Event?

Saturday, February 01, 2014

The cost of a thirty second advertising slot at the annual Superbowl final is immense. This year advertisers are paying $4 million dollars for a 30 second advertisement during America's largest televised event. But big hits on the social web often produced at a tiny fraction of the cost challenge the conventional view that mega bucks spent reaching a TV audience remains a viable way of using the marketing dollars. This short news video from the Financial Times is a useful reminder of the importance attached to brand advertising by some of America's biggest consumer products.

Government looks to abandon use of Microsoft Office to save money

It was announced yesterday that the Government is planning to abandon its use of expensive software such as Microsoft Office (see article in the Guardian here) partly as a way of reducing costs but also as a means of breaking some of the software company's 'oligopolistic' stranglehold on the market.

As well as offering an example of Government policy to combat market failure, this story gives us a little insight into the issue of contestability in the software industry.

So farewell, then, Facebook! That is the conclusion of a highly technical paper by two Princeton researchers, John Cannarella and Joshua Spechler, which received a lot of publicity in the press last week.

Capping Bonuses for Bankers - Unintended Consequences

Friday, January 24, 2014

Capping seems to be all the rage at the moment. We read of capping electricity and gas prices, capping welfare payments for families ... and now a proposed cap on bonuses for bankers is being put forward by the EU and by the Labour Party. 

In this article, Tim Harford cuts to the chase and highlights the contradictions in the EU blanket policy on capping bankers' bonuses. It is a good example of a policy where the unintended consequences include the probably that banking salaries would rise still further.

Under the EU proposal, a cap on rewards would limit payouts to banking executives to annual pay - or twice that only if shareholders approve.

Energy saving tips from the Government - effective Government intervention

Proposing Government intervention strategies for dealing with externality market failure is a common enough exam question.  Many of my students will concentrate on the use of indirect taxation, subsidies, pollution permits or regulation as a method of reducing consumption - often forgetting that the Government can use good, old-fashioned advice as a way of altering purchasing patterns.

Non-Price Competition - Paperless Receipts and Immediate Gratification

Friday, January 03, 2014

Here are some examples of changes in the nature of non-price competition in the oligopolistic supermarket industry. The success of the My Waitrose card (now used by 3 million customers) has catapulted Waitrose into 2nd place for the largest retailer of hot tea and coffee drinks in the UK. They are now second only to McDonald's and some distance ahead of Costa, Starbucks and other well-known high street brands.

Unit 3 Micro: Event Cinema - Seat with a Vue

Sunday, December 29, 2013

Event cinema is set to become big business both in fully digital cinemas in the UK. Cinemas that have invested in the very best digital screening technology can now harness their capacity to run non-conventional programming including live theatre, multi-player gaming and screening of live sporting events. 

Tim Richards from Vue Cinemas (one of Tutor2u's major commercial partners) is interviewed here by the Economist about the opportunities of event cinema to serve a more diverse audience and leverage the assets of a cinema to improve profitability. 

Vue has certainly been in the forefront of making huge investments in fully digital projection on huge screens - this is just one of the reasons we love hosting live Tutor2u events in some of the top Vue facilities in the UK.  

Watch the six minute interview and consider some of the non-price factors that are important in winning the battle for market share in the cinema industry and in broadening the appeal of cinemas to a wider range of audiences and tastes.

Competition Commission investigating the Car Insurance Market

Tuesday, December 17, 2013

You may have seen news reports today about the Competition Commission announcing that it will continue its investigation into the car insurance market having decided that there are concerns to be addressed. The headlines concentrate on the market failure caused by the current system of non-fault claimants organising their own replacement vehicles (and then charging the at-fault insurers) but I thought it was just as interesting that the CC are looking at the relationship between the insurers and price comparison websites.

Wow Economics! Update the ‘Average Wage Game’ and ‘Values of Occupations’ game

Monday, December 16, 2013

Calling all previous delegates of our Wow Economics CPD events! If you attended Wow Economics last academic year (2012-2013) you may recall an activity called 'The Average Wage Game'. If you have attended this academic year I'm sure you will remember the activity 'The Value of Occupations'. Both resources were aimed at introducing or stimulating initial discussion about wage determination before moving on to developing the theory behind Marginal Revenue Product and its value.

Both activities relied upon data relating to UK wage rates by occupation. This data was based upon information taken from what was the latest ONS report on wages in the UK (November 2012). I said, at the time, that when the data was updated I would forward information for both games so that teachers can update them accordingly. This information is now here and ready for you to download!

London’s Super Sewer

Friday, December 13, 2013

With London’s Victorian sewage system struggling to cope, the 25km Thames Tideway tunnel is intended to boost capacity. But the £4.2bn Super Sewer project has run into considerable and vocal opposition. London's main sewers are over 150 years old and built for a city for 2.5 million people. The population of London is now over 8 million and when heavy rainfall arrives, there are frequent and sizeable discharges of raw sewage into the river Thames. 39 million tonnes of untreated sewage flushes into the Thames in a typical year - that’s enough to fill the Royal Albert Hall 450 times. The sewage discharges puts the UK in breach of the EU Urban Wastewater Treatment Directive.

Critics of Thames Water argue that they have under spent on sewage system maintenance over the years despite recording persistently high profits. Thames Water announced £150 million profits in 2012.

Residents around the 21 proposed construction sites have protested about the externalities connected to the project. Other opponents argue that the money would be better spent on cheaper sustainable urban drainage techniques.

Future generations will benefit but today's water users will pay most of the construction cost with higher water bills imminent for a number of years to come. The Thames Water proposes adding £70 to £80 a year indefinitely to the average bill of Londoners to fund the 16-mile sewer from Acton in west London to Abbey Mills in east London. But a report by Bloomberg New Energy Finance calculates that the tunnel could be built for between £30 and £35 per household per year

Guardian: London super sewer 'should be scrapped in favour of cheaper projects'

Britain’s New Industrial Policy: Can We Learn from the Mistakes of the Past?

The phrase ‘industrial policy’ seems to take us decades back in time. In 1964, a powerful catchphrase of the new Labour Prime Minister, Harold Wilson, was the need for Britain to embrace the ‘white heat of the technological revolution’. Sadly, by the 1970s this vision had deteriorated into a list of institutions, stuffed with dull businessmen and trade unionists, meeting to decide how to prop up yet another failed sector of the UK economy.

But the concept is now back in vogue. Perhaps surprisingly, given the historical experience, the coalition chose to preserve Labour’s Technology Strategy Board (TSB) quango. The TSB has a budget of £400 million to “accelerate UK economic growth by stimulating and supporting business-led innovation”. A key way in which it plans to do this is through the purchasing decisions of the public sector.

Have Bankers Been Practising Socialism?  The Debate About the Top 1 Per Cent

Wednesday, December 11, 2013

Boris Johnson has got into trouble for his statement that it is "surely relevant to a conversation about equality" that just 2 per cent of “our species” has an IQ over 130. Over the past couple of years, the Occupy movement has made headlines by attacking the top 1 per cent.

The summer 2013 edition of the top American Journal of Economic Perspectives focuses specifically on the “Top 1 Per Cent”. This is written almost exclusively in English rather than maths, and top economists debate a range of intriguing questions.

Wages and Sharing the Fruits of Economics Growth

Thursday, December 05, 2013

Employees in the UK are not being denied their fair share of economic growth, according to research by João Paulo Pessoa and Professor John Van Reenen, director of the Centre for Economic Performance at LSE. Their investigation of claims that wage growth has become ‘decoupled’ from productivity growth finds that decoupling has been overstated and cannot be used to justify redressing the balance between wages and profits.

Unit 3 Micro: The Future of Gaming

Friday, November 29, 2013

The release of two major new iterations of games console including the PS4 is an opportune moment to take stock of the transformation of the oligopolistic computer gaming industry into one whose revenues now exceed films and where social gaming, connectivity and collaboration are features of an industry where dynamic efficiency is crucial. Paul Mason from Channel 4 news reports in this short clip.

Unit 3 Micro: Cartels and their Ringleaders

Price fixing and bid rigging by groups of firms in Europe are not solely the preserve of highly concentrated industries. According to research by Professor Stephan Davies and Dr Oindrila De, even industries with relatively large numbers of firms feature such anti-competitive practices – and they typically have a ‘ringleader’, which organises and enforces the cartel. Their study, published in the November 2013 issue of the Economic Journal, finds that roughly a quarter of the 89 cartels detected by the European Commission over the past two decades have a ringleader or ringleaders. In cartels with relatively large numbers of firms, the ringleader tends to be the dominant firm, acting aggressively to set prices and ensure that smaller firms fall in line.

Unit 3 Micro: Costs and Pricing for the PS4

Sunday, November 24, 2013

The launch of Sony's PS4 alongside Microsoft's XBox One signals the beginning of a highly intense competitive battle in the oligopolistic games console market. With both the new consoles being launched in time for the crucial Christmas sales period, pricing strategy is crucial in order to gain maximum market share.

In the US, Sony has priced the PS4 at $399 (retail). Of course that is the retail price. Distributors will be wanting to make their margin on each unit sold. So how much does it cost Sony to make a new PS4?
