Perfect weather and a bumper wheat crop – impact on the market

Sunday, September 07, 2014

A great example to start you off looking at how economists understand markets: after a run of rain-wrecked years, British farmers are bringing in the last of what looks like a bumper cereals harvest. 2014 could be the biggest yield ever for wheat. Good news. But for whom?

Business Economics - hard hats on for banana wars

Saturday, September 06, 2014

We are taking business growth as our first topic for unit 3 this term, and the FT has some excellent resources to introduce the subject, in th form of short Lex video discussions. The three that I have used look at Fyffes attempt to buy Chiquita, which has been 'gatecrashed' by two Brazilian firms, Carillion's bid to buy the much bigger Balfour Beatty, and then to cover demergers, Barclays' sale of their Spanish business.

Tim Harford on Monopoly and Innovation

Wednesday, August 27, 2014

Tim Harford, the Undercover Economist has written an excellent article here on the impact of large scale monopolistic businesses on our economic welfare. Originally published in the Financial Times, you can read it in full by clicking this link to Tim's website. http://timharford.com/2014/08/monopoly-is-a-bureau...

Are highly profitable monopolies a crucial source of innovation (improvements in dynamic efficiency)? Or should we be looking for rigorous competition policy to address the X-inefficiencies often associated with established market dominance?

Tim writes 

"The ferocious cut and thrust of smaller competitors seems a more reliable way to produce many of the everyday innovations that matter."

BHP Billiton announces plans for a demerger

Tuesday, August 19, 2014

De-mergers often figure in EdExcel Unit 3 questions e.g. on the structured multiple choice - so this one from mining giant BHP Billiton is a good example to be aware of and to understand the key drivers behind the decision. BHP Billiton plan to sell (divest) non-core assets such as their aluminium, manganese and nickel mines.

As always - focusing on core competencies, streamlining operations to avoid diseconomies of scale lie at the heart of the de-merger process

BHP Billiton is hugely profitable! BHP achieved full-year profits last year of $US13.8bn helped by a 15th straight year of record iron ore production.

More here on the planned demerger from Reuters Business News

Business Economics - Succeeding in the US Market

Saturday, August 16, 2014

This article from the BBC news site is excellent for teachers and students wanting some applied examples of businesses that have succeeded in building through organic growth a durable market presence in the USA and some examples of bigger names / corporations that have failed.What are the key ingredients? How do import tariffs affect a business such as Brompton Bikes?

The Economics of the Blockbuster

Wednesday, August 13, 2014

Why do we get summer holiday blockbusters? They seem to matter more and more to Hollywood studios. According to one professor "the entertainment industry is moving more towards a winner-take-all-market". Yet it wasn't supposed to be like this. A best-selling 2008 book, The Long Tail, argued that the mainstream was going to be "shattered into a zillion different cultural shards," as fickle consumers "scattered to the winds" using the internet to find the books, films and songs that met their unique taste. So what might be going on?

Price Discrimination in the the EU Vehicle Hire Market

Tuesday, August 12, 2014

An almost perfect example of price discrimination is evident in this market revealed on the BBC online news site - read this section carefully!

"Charges vary for some motorists, even if they are picking up the same vehicle from the same location and from the same hire company."

Then read through the article to find clues as to how some vehicle hire businesses have been able to segment the market and discriminate between drivers from different countries inside the EU.

The regulators are onto the issue - expect some action unless vehicle hire businesses adjust their pricing tactics!

Sunday, August 03, 2014

P&G has announced that it will look to focus on a much smaller number of consumer brands and cull up to 100 brands from its extensive product portfolio. In a classic example of product portfolio management, P&G wants to focus on those 70-80 key brands that have existing strong market shares and/or fast growth prospects.

Externalities of Waste - Do we throw too much stuff away?

Friday, July 25, 2014

This is a super report from BBC Newsnight on the issue of our throwaway society and the externalities of waste. How can the link between consumption and the discarding of unwanted and broken products be weakened? What role can innovation play - for example the rise of modular phones where parts can be replaced when broken. The fundamental problem is that traditional manufacturing business models are based on mass production and sales. How are increasing world commodity prices affecting this model?

The Economics of Pay What You Want

Wednesday, July 23, 2014

People do care about fairness, social norms and not just about a cold calculation of marginal cost and marginal benefit. In this excellent short interview on BBC World, Joe Gladstone, Behavioural Scientist at the University of Cambridge, discusses the new form of "Pay What You Want" pricing. This means consumers can decide themselves how much they want to pay for a good or service. The catalyst is that several French hotels are experimenting with a pay what you like approach for their guests.

Siemens Boss on possible redindustrialisation of the UK economy

Sunday, July 20, 2014

This interview with Jurgen Maier of Siemens is well worth reading on several different levels. It challenges the conventional wisdom that UK will always lag behind Germany in terms of high value added manufacturing; it refers to the economics risks of Brexit (Britain leaving the EU) and it also stresses the importance to the UK of foreign investment from German businesses many of which have been in the Uk since well before the first World War - Siemens and Bosch are two well-known examples.

Shareholder activism at the Royal Mail

Shareholder activism regarding executive pay is covered in this article from the Guardian. Note too the emergence of TNT Post as a competitor in the cities for final mile delivery of business and household mail - the mail market is becoming more contestable.

The Royal Mail's latest market report is an interesting read for those who want to study market dynamics in more details - for example the continued growth (but high contestability) in parcels contrasted with a trend decline in the volume of letters sent through the post - click here for the 2014 market overview: http://ar2013-14.royalmailgroup.com/overview/marke...

Calculation time! CMA recommends banks provision of current accounts should be investigated

Friday, July 18, 2014

Today’s announcement that the Competition and Markets Authority (CMA) are recommending that the High Street Banks’ provision of current accounts should be investigated for lack of competition may not surprise many. The case study may be valuable when looking at competition in oligopolistic markets and a report can be found from this link.  The BBC take on the story can be found from this link.

I also thought it offered a chance to do some calculations! Given my current theme of bringing the new levels of assessment of numeracy and quantitative methods in the 2015 specifications of A level economics ever increasingly to the attention of our teaching community, where better to do some number work than when looking at market share in the banking industry!

Dropbox and the failures behind it

Tuesday, July 15, 2014

According to some sources, Dropbox was the 37th online storage solution to be developed for the web - but despite early failures and late entry it has emerged as the cloud storage product of choice for over 300 million people. The firm is now estimated to be worth about £5.9bn.

This BBC article looks at the background to the story. Article can be found here: http://www.bbc.co.uk/news/business-27579790

Contestable Markets - A New Retail Landscape

Monday, July 07, 2014

Here is a short FT background video on the challenges facing established food retailers in the UK. The supermarket is under pressure. They face competition from both hard discounters and upmarket retailers. The FT's Andrea Felsted visits Romford, on the outskirts of London, to examine how supermarkets are adapting to their new retail landscape. The Guardian's articles in changing competition in the food retail sector provide some excellent background pieces - click here to access: http://www.theguardian.com/business/supermarkets

Transport: competition in the cross channel market

Wednesday, July 02, 2014

When the Channel Tunnel opened in May 1994 bosses of many ferry companies were glum. But it was the backers of the channel tunnel who lost a fortune: according to The Economist (the source of the graph above), the train through the tunnel was meant to carry 28m passengers a year by 2010. Ferries were expected to lose foot passengers, cars and lorries. Like many predictions in business, this soon came to seem wrong; now it seems wrong only in the timing. Now it looks like competition in the market may be about to collapse, with ferries coming under increasing pressure.

Paul Ormerod: Innovation, Job Losses and Living Standards

Wednesday, June 18, 2014

Here is your starter for ten. What do the Uber app and David Ricardo have in common? Ricardo, I hear you ask. Scarcely known outside academic economics, he ranks equal with Adam Smith and Keynes as the greatest ever British economist. His classic Principles of Political Economy was published in 1816. He made millions of pounds on the stock market, at a time when a million was a vast amount of money.

​Disruptive technology: Uber

Wednesday, June 11, 2014

Technology always disrupts markets. It provides dynamic efficiency improvements, creates new markets, destroys old ones, and in some cases destroys monopolies and in others, creates new monopolies.

Unit 3 Micro: Should Tesco be broken up?

Saturday, June 07, 2014

The supermarket giant Tesco is under increasing pressure! Tesco is Britain’s biggest retailer (it has 29% of the UK groceries market) and the biggest private-sector employer, and it runs about 7,000 stores worldwide. But it is facing significant commercial challenges from discount retailers such as Aldi and Lidl and seems to be squeezed in the middle as other shoppers look for the value proposition in stores such as Waitrose. Their recent trading figures made for sorry reading. For the three months to 24 May 2014, Tesco said like-for-like UK sales including VAT and excluding petrol fell 3.7%.

Is there a case for breaking up Tesco and getting the business to re-focus on what it does best? Two journalists from the Financial Times argue it out in the video below:

Transport Economics: The Return of Trams - Benefits and Costs

Sunday, June 01, 2014

Trams have been experiencing a revival in a number of towns and cities in the past few decades. Edinburgh is the latest city to invest in trams, and hopes they will boost local economy. But do the benefits outweigh costs? Manchester, Sheffield, Blackpool, Nottingham, Newcastle and Croydon have all installed trams / light rail and others are considering investment. 

The Edinburgh trams at running (at last) but the jury will remain out for a long time about their net impact on economic activity, traffic congestion and the broader health of Edinburgh and the local environs.

Unit 3 Micro: Ban on Eurotunnel ferry service confirmed by CMA

Friday, May 30, 2014

An important judgement from the newly established Competition and Markets Authority (CMA). They believe that competition is best served by having three major cross-channel service operators - namely EuroTunnel (rail) and two ferry operators.

The CMA has ruled against EuroTunnel being able to cross-subsidise the loss-making MyFerryLink on the Dover to Calais service because in doing so, it is likely to lead to the market exit of a rival provider and ultimately cause higher prices for consumers.

Reducing Contestability using the ‘sardines’ technique

Thursday, May 15, 2014

A good article in The Economist recently, arguing that firms may be cramming markets in order to keep rivals out. Raising barriers to entry serves to reduce the levels of competition in markets, or makes them less ‘contestable’.

UK Economy: The Economics of Falling Real Wages

Thursday, May 01, 2014

The prospects of significant wage increases for typical UK workers are bleak, according to Professors David Blanchflower and Stephen Machin writing in the Spring 2014 issue of CentrePiece magazine from the London School of Economics.

It is quite clear that the economy is still well below full employment and there is a large amount of slack in the labour market, they say. There is little evidence of widespread skill shortages, which would push up wages; and public sector pay freezes with continuing redundancies continue to push down on workers’ bargaining power.

Unit 3 Micro: Tanzania’s cola wars

Saturday, April 19, 2014

Tanzanian cola producers are taking on Coca Cola and making headway in the battle for market share. Despite economic growth, there is a fragile middle class vulnerable to changes in world commodity prices and unstable employment and wages. This opens up an opportunity for indigenous food and drinks manufacturers who might be able to supply products at a lower price harnessing environmental aims such as recycling the majority of plastic bottles used.

Policies to reduce collusion

Friday, April 18, 2014

Investigating and understanding price fixing and collusion are an important part of analysing behaviour in oligopolistic markets. Not all of these corrupt practices are headline grabbers: most are in such unglamorous areas as ball-bearings and cargo rates, which go on unnoticed for years, quietly bumping up the end cost to consumers of all manner of goods and services.

What steps can be taken to undermine the incentives for business to engage in these illegal activities?

Unit 2 Macro: Fiscal Policy to improve Net Trade

Tuesday, April 08, 2014

Here is a good applied example of how fiscal policy can be used to help improve the UK's net trade position. Export finance is often a problem especially for small and medium sized businesses looking to expand beyond the domestic economy to new export markets. Improving the trade position is a key aspect of re-balancing the economy and make the recovery more sustainable.

Lancashire and London have dominated the Premier League.  Can it last?

Thursday, April 03, 2014

The Premier League season draws to an exciting close. It is by no means clear who will be champions, or who will gain the coveted top five European qualifying spots. There could even be a surprise. If Liverpool win, for the first time since 1995 a team from outside Manchester and North London will be crowned. Even then it was Blackburn. In the previous 21 seasons of the Premier League, all the winners have come from either the North West or London. So a Scouse victory would not alter this.

Unit 4 Macro: Economic Benefits of EU Membership

Membership of the European Union (EU) has had a big positive effect on average incomes in all but one of its member countries. That is the central finding of research by Nauro Campos, Fabrizio Coricelli and Luigi Moretti, to be presented at the Royal Economic Society’s 2014 annual conference. They also find that the more financially developed countries have grown significantly faster after joining the EU.

Wednesday, April 02, 2014

Unit 3 Micro: Energy firms face competition inquiry

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.
