For some people, a pint of beer is a regular thing each week. Add all your pints of beer together, then add your friend’s pints, their friends’ pints and … you get the idea. Once you’ve done that for the entire population, you have an estimate of total beer consumption in the UK. This can then be compared with total consumption of beer in other countries and between continents.
Prior to 2007, Europe and the Americas were the biggest beer drinking continents, but since then, Asia has emerged as the leader of pints of beer consumed, drinking 67bn litres of beer compared with the Americas’ 57bn and Europe’s 51bn in 2011. In per capita terms, Asia is still some way off, with Japan leading the way as the highest Asian country in 41st place, consuming 64 litres of beer per year per capita of the population. So how is this relevant to economics and business?
Consumption of anything provides jobs – bar workers, manufacturers and in the case of beer, probably law enforcement! It probably also increases utility – after all, why consume it if it’s not going to give you some degree of satisfaction!
We can analyse the demand for beer and see how it varies with changes in price and income. Minimum prices for alcohol have been proposed as a means of reducing consumption, and tax and excise duties are always linked to alcoholic beverages and clearly have an effect on demand. In this case, however, we can also consider the emergence of Asia and how tastes have changed. It is the fastest growing beer market in the world; so what can we deduce from that? As the BBC News article states, it is ‘a sign of a young, upwardly mobile, and increasingly hedonistic population.’
Experts also say that the increased consumption of beer in Asian countries is closely correlated with growing incomes and prosperity. A consumer research analyst from Standard Chartered, Nirgunan Tiruchelvam, said:
“Beer has a clearer correlation with strong economic growth … People tend to drink beer in times of growth. They drink spirits when times are good and when times are bad.”
Data suggest that when a certain level of prosperity is reached in a nation, beer sales begin to rise. As many Asian economies begin to develop rapidly, beer sales have taken off. This could be regarded as a good thing for Europe. With stagnant Western economies, beer producers within Europe may be grateful for a growing demand in Asia. Indeed, many of the world’s biggest breweries are expanding rapidly, providing jobs and income. Consumers in Europe will also be happy to see that beer production remains profitable in other parts of the world. With unemployment still high and recession ongoing, a pint of beer will be a much needed pick-me-up for many people. At least, that’s what the evidence from the Great Depression of the 1930s suggested!!
It’s not good news for everyone, however. Beer production has also increased in Asian countries, most notably in China, which now leads the world as the largest beer producer. This clearly reduces the export potential for European beer producers.
Also, many argue that the growing consumption of beer in Asia is simply an illustration of growing Western influence and it is likely to create severe medical problems in the future. Binge drinking and under-age consumption is already a big problem in Western countries and this could soon begin to extend across the world. The following articles consider the growth in consumption of beer.

The housing market is crucial in any economy, as it provides so many jobs in related industries. It is frequently a good signal of how buoyant the economy is. With recession in the UK, mortgage rationing continuing and many homeowners having to find 20% deposits to buy a house, many would expect the housing market to be showing signs of trouble.
And to some extent this is the case. Studies on house prices have clearly shown how unpredictable this market is and prices remain 0.7% below what they were a year ago. However, in August house prices increased, recording their biggest rise in two and a half years, at 1.3%. For many, this rise was a surprise, but came as a welcome relief following the declines in previous months. Despite this rise, analysts have suggested that this trend is unlikely to continue throughout the rest of the year, as the demand for houses remains weak. Robert Gardner, the Chief Economist at Nationwide said:
“Given the difficult economic backdrop, the extent of the rebound in August is a little surprising. However, we should never read too much into one month’s data, especially since monthly price changes have been impacted by a number of one-off factors this year, such as the ending of the stamp duty holiday for first time buyers’.
So, what is behind this upward trend? Nationwide’s Chief Economist says that it could be explained by a resilient labour market, where employment has risen in recent months, despite the recession. The labour market undoubtedly has a big effect on the housing market, as mortgages do take up so a large percentage of take-home pay.
However, another key factor that affects house prices is the availability of mortgages. The Bank of England and Treasury launched the Funding for Lending Scheme at the beginning of August in a bid to make mortgages cheaper and more easily available. However, analysts suggest that the scheme is yet to have an effect. Furthermore, until deposit requirements are eased, that first step on the property ladder will remain elusive for many people. Mortgage approvals did increase slightly in July, but still remain a major barrier for the housing market to really boom.
The following articles consider this ‘surprising’ rise in house prices and the factors behind it.

In its report A Distorted Debate: the need for clarity on Debt, Deficit and Coalition Aims, the Centre for Policy Studies claims that the public is confused by economic terminology surrounding the government’s finances. We try and understand this confusion and offer a bath-time solution!
In a survey conducted for the Centre for Policy Studies only 10 per cent of Britons knew that despite cuts to parts of the government’s spending plans, the stock of public sector debt (also known as the national debt) is expected to rise by a further £60 billion by 2015. Rather, 47 per cent of respondents thought that debt would have fallen by this amount.
The confusion is not terribly surprising because there are two important core economic concepts that can confuse: stocks and flows. To try to help we will show how reference to a bath tub can hopefully eliminate the confusion. However, first, let us considerthe Coalition government’s principal fiscal objective. Its so-called fiscal mandate is for the cyclically-adjusted current budget to be in balance by 2015/16. In simple terms, the government wants to be able afford its day-to-day expenditures by this date, after taking into account where the economy is in the business cycle. In other words, if the economy’s output was at its sustainable or potential level in 2015-16 the government should be able to raise sufficient taxes to meet what it refers to as current expenditures. This would still allow the government to borrow to fund investment expenditure, e.g. infrastructural projects, which are enjoyed or consumed over a period of time.
An important thing to note about the fiscal mandate is that the government can expect to need to borrow money in order to afford its current expenditures up to 2015/16. Even beyond this date, assuming that the mandate can be met, it is likely to need money to afford capital expenditures. This is where we introduce the bath tub. Think of government spending as water coming through the bath taps while the taxes that government collect are water leaving through the plug hole. Therefore, spending and tax receipts are flows. If the water pouring into the bath (spending) is greater than the water leaving the bath (tax receipts), the level of water in the bath will rise. You can think of the water level in the bath as the stock of national debt. Therefore, if government is spending more than it receives it needs to borrow money. Borrowing is therefore a flow concept too. As it borrows, the stock of debt (the amount of water in our bath tub) rises.
So we know that government will continue to borrow in the near future. What it is hoping to be able to do, year by year, is begin to borrow less. It wants the deficit to fall. Then, if it can meet its target, it will at least be able to afford current expenditure (after adjustment for where the economy is in the cycle) by 2015/16. As the deficit begins to decline then the stock of debt will rise less quickly. But, the bath tub will continue to fill because more is flowing through the taps than is leaving through the plug hole. However, it will fill less quickly.
What our use of the bath tub analogy demonstrates is the confusion that can be caused when economic terminology is misused. It is important that the terms debt and deficit be used carefully and correctly. Therefore, the next time you are sitting in bath see if you can be the next Chancellor by understanding these key economic concepts.

- Explain what will happen to both the size of the government’s deficit and to its stock of debt if borrowing begins to decline.
- Can the stock of government debt fall if the government continues to borrow? Can the ratio of the stock of government debt fall relative to GDP (i.e. Debt/GDP), if government continues to borrow?
- With examples, explain the differences between the government’s current and investment (capital) expenditures.
- What are the economic arguments for trying to cut the deficit quickly or more slowly?
With droughts and poor harvests in both North America and in Russia and the Ukraine, there are worries that food prices are likely to see sharp rises in the coming months. This is clearly bad news for consumers, especially the poor for whom food accounts for a large proportion of expenditure.
But it’s also bad news more generally, as higher food prices are likely to have a dampening effect on the global economy, struggling to recover from five years of low or negative growth. And it’s not just food prices. Oil prices are rising again. Since mid June, they have risen by nearly 25%. This too is likely to have a dampening effect.
Another contributing factor to rising food prices is a response, in part, to rising oil prices. This is the diversion of land from growing food to growing crops for biofuels.
G20 countries held a conference call on 28 August to discuss food prices. Although representatives decided against an emergency meeting, they agreed to reassess the situation in a few weeks when the size of the US harvest would be clearer. If the situation proved as bad as feared, then the G20 would call an emergency meeting of the Rapid Response Forum, to consider what could be done.
But is the sole cause of rising food prices a lack of production? Are there other problems on the supply side, such as poor distribution systems and waste? And what about the role of demand? How is this contributing to long-term increases in food prices? The articles consider these various factors and what can be done to dampen food prices.

Last year, an academic discovered that the only two firms on Amazon selling new copies of a classic biology textbook were charging well over $1 million (plus $3.99 for shipping!). Furthermore, when he checked the next day, prices had risen even further to nearly $2.8 million! Intrigued by this strange pricing behaviour, he started to investigate the prices further.
In oligopoly markets with a small number of players, firms must make strategic decisions taking into account how they expect their rivals will react. One option in today’s online market places is for firms to use computer algorithms which automatically adjust their prices according to the prices their rivals are charging. The results of his investigation suggested that this was exactly what was causing the prices for this textbook to be so high.
One of the firms appeared to adopt a pricing rule which set its price at 0.9983 times the price of the other firm. This seems to make sense – this firm wants to undercut its rival in order to be more likely to sell its copy. However, if both firms operated under this strategy, we would expect to see prices falling over time (see also). In contrast, the strategy of the other firm appeared to be to price 1.270589 above its rival’s price. Why would it want to try to make sure it was always more expensive that its rival? The academic’s plausible explanation was that:
“…they do not actually possess the book. Rather, they noticed that someone else listed a copy for sale, and so they put it up as well – relying on their better feedback record to attract buyers. But, of course, if someone actually orders the book, they have to get it – so they have to set their price significantly higher – say 1.27059 times higher – than the price they’d have to pay to get the book elsewhere.”
Put both of these pricing rules together and prices will continuously rise over time! This was exactly what the academic observed for over a week, until human intervention appears to have returned prices to a more sensible level.
As Tim Harford discusses in his recent blog post, it had been hoped that online market places would result in very low prices because the high degree of price transparency increases competition. Clearly the prices Amazon was initially charging for the textbook didn’t support this theory and even after human intervention prices would seem to be well above marginal production costs. However, as the blog post goes on to explain, we should not necessarily expect price transparency always to lead to low prices. Economic theory shows us that in oligopoly markets, when a small number of players interact repeatedly, they may be able to collude tacitly on high prices. Furthermore, a high degree of price transparency may help such collusive behaviour because it makes it easier for firms to detect cheating by a rival.
