What does it take to create a successful business? From the looks of it: mud, electric barbed wire, icy water, enormous walls to climb, big jumps to make, team work and complete exhaustion – the recipe for every successful business.

Tough Mudder was founded in 2010 and runs gruelling extreme obstacle courses for anyone mad enough to think it might be fun. In the BBC News article below, you’ll see that there is a discussion as to intellectual property rights, but whatever the outcome, this company has become the main provider of such extreme sports in a remarkably short period of time. Within 2 years of being established, it had gained 500,000 participants and now records annual revenues of more than £60m. Add to this, that there has no external funding and this organic growth is beyond impressive.

A key question, then, is what creates such a successful business? Without a doubt, this depends on the product you are selling and the market a firm is in, but there are some aspects that apply across the board. Understanding what your customers want is crucial, as they represent your demand. Differentiating your product to create inelastic demand may be a good strategy to enable price rises, without losing a large number of sales, but the differentiated product is essential in establishing demand, loyalty and reputation. Marketing something in the right way and to the right audience is crucial – word-of-mouth is often the most effective form of advertising.

If you have all of these aspects, then you have the makings of a successful business. The next step is putting it into practice and climbing those high walls, taking the big jumps and hopefully avoiding the mud and ice. The following article considers Will Dean and his fast growing business.

In December 2013, Uruguay passed a law permitting the growing, distribution and consumption of marijuana. The legislation comes into effect in April 2014. The state will regulate the industry to ensure good quality strains of the crop are grown and sold. It will also tax the industry.

Uruguay is the first country to legalise cannabis, but in July 2012, Colorado and Washington states in the USA passed laws permitting the sale and possession of small amounts of the drug for recreational use. (It was already legal to possess the drug for medical use.) The laws took effect a few months later. It is heavily taxed, however, especially in Washington, where it is taxed at a rate of 25% three times over: when it is sold to the processor; when the processor sells it to the retailer; and when the retailer sells it to the consumer. In Massachusetts, Nevada and Oregon, medical cannabis shops will be permitted to open this year. In the Netherlands, although the sale of cannabis is still illegal, ‘coffee shops’ are permitted to sell people up to 5 grams per day.

So should cannabis be legalised? People have very strong views on the subject and this can make a calm assessment of the issue more difficult. The economist’s approach to legalising cannabis involves seeking to identify and measure the costs and benefits of doing so. If the benefits exceed the costs, then it should be legalised; if not, it should remain illegal (or made illegal). The problem is that the size of the costs and benefits are not easy calculate as they involve estimates of things such as consumption levels, tax revenues, crime reduction, the effects on the consumption of other drugs, including legal drugs such as alcohol and tobacco.

Nevertheless, various estimates of these costs and benefits have been made and provide a basis for discussion.

Possible benefits of cannabis legalisation include: increased tax revenues for the government; reduction in crime, and hence reduction in law enforcement and prison costs; encouraging people with addiction problems to seek help, as they would not fear arrest; reduction in the price, benefiting users; regulating quality of the drug; reducing the consumption of alcohol and more dangerous drugs if these are substitutes for cannabis; moral arguments concerning freedom of individuals to choose their lifestyle.

Possible costs include: increased consumption of cannabis, with attendant health and social side effects; increased consumption of other drugs if they are complements, or if cannabis is an ‘entry level’ drug to harder drugs; moral objections to drug taking.

Clearly some of these costs and benefits are easier to measure than others. Moral arguments are almost impossible to assess quantitatively, even when various underlying moral standpoints are agreed.

The following articles look at recent events and at the arguments, both economic and non-economic.

According to the supply and demand model, we would expect the price of turkeys to be high at this time of year. After all, last Christmas in the UK over 10 million turkeys were consumed and, therefore, this high level of demand should cause prices to rise. This is certainly what happens in other markets when there is a substantial increase in demand.

However, evidence from Thanksgiving in the USA suggests that this might not be the case. According to this article from the New York Times, data suggests that the price of frozen turkeys in the US falls by around 9% between October and November, coinciding with the substantial increase in demand for Thanksgiving celebrations. The article then goes on to suggest a number of plausible demand and supply-side explanations for this fall in price.

The ONS has just published two of its major annual publications on income and expenditure in the UK. The first is the Annual Survey of Hours and Earnings (ASHE) and looks at earnings from 1998 to 2013. The second is Family Spending and looks at the level and pattern of household spending each year from 2001 to 2012.

Figures from the two publications show that average real incomes have fallen each year since 2008. This is illustrated in the first chart (click here for a PowerPoint of the chart). They also show that household expenditure in real terms is falling and is at the lowest level since 2006.

Overall picture
In 2012, households’ average weekly disposable income was £597. In 2012 prices, this was down from £621 in 2010 (after the recession) and £659 in 2008 (before the recession).

Household expenditure is at its lowest level in real terms for over a decade. In 2012 households spent on average £489.00 per week. In 2012 prices, this compares with £521.90 in 2001/2 and £533.80 in 2006 (the peak year).

Picture for particular income groups and products
Although average real incomes have fallen, not everyone has been affected the same. For example, not all occupations have seen a fall in incomes (see the table at the end of the BBC article, Earnings rise slower than inflation for fifth year running). Also, as income distribution has become less equal, so those in lower income groups have seen their real incomes fall the fastest. This is partly the result of nominal wages rising less fast for low-paid workers and partly the result of price increases for various essentials, such as food and power being greater than the rate of inflation, and these products constituting a higher proportion of expenditure for poor people than rich people (see Squeezed Britain 2013).

Likewise expenditure hasn’t fallen on all categories of product. Since 2006, real expenditure on clothing and footwear and on housing, fuel and power has risen. The second chart illustrates expenditure on some of the different categories and how the balance has changed (click here for a PowerPoint). This partly reflects the changes in prices of products, with some items, such as electricity, gas and rent having risen faster than the average, and with the demand for such items being relatively price inelastic.

The changing pattern is also partly the result of different income elasticities of demand for different items. Thus, with falling real incomes, the proportion of income spent on products with a low income elasticity of demand is likely to rise.

Expenditure also varies by income group. People on higher incomes tend to spend a greater proportion of their income on things such as leisure activities (e.g. eating out and holidays), motoring, and clothing and footwear. Poorer people tend to spend proportionately more on food and drink, and on electricity, gas and rent (even net of housing benefit). These differences are illustrated in the third chart which looks at certain categories of expenditure of three different disposable income groups: the poorest 10% (decile), the richest 10% and the 6th decile (i.e. the 6th group up from the bottom – the group with average or just above average income) (click here for a PowerPoint for the chart). Detailed figures can be found here, which is Table 3.2 from Family Spending.

Just as the time-series data looking at changing income and expenditure over time can illustrate the different income elasticities of demand for different products, so can the cross-sectional data in Tables 3.1 and 3.2 of Family Spending.

The price of road fuel is falling. Petrol and diesel prices in the UK are now at their lowest level since February 2011. The average pump price for a litre of unleaded petrol has fallen to 130.44p in November – down nearly 8p per litre since September.

According to the AA, the reduction in price equates to a fall in the average monthly expenditure on petrol of a two-car family of £14.49 – down from £252.54 to £238.05. This saving can be used for spending on other things and can thus help to boost real aggregate demand. The fall in price has also helped to reduce inflation.

But will lower fuel prices lead to a rise in fuel consumption? In other words, will some of the savings people make when filling up be used for extra journeys? If so, how much extra will people consume? This, of course depends on the price elasticity of demand.

The following articles explain why the price of road fuel has fallen and look at its consequences.
