When you hear about China, it’s often regarding their huge population, their strong growth or their dominance in exports. But, when it comes to baby milk, China is certainly an importer – and a big one at that. For many new parents, getting the ‘real thing’ when it comes to baby formula is absolutely essential.

Chinese baby formula is feared by many new parents, due to the potential for it to contain hormones and dangerous chemicals. This has led them to go to great lengths to ensure they have sufficient supplies of imported baby formula, often only trusting it if it has been hand carried from overseas. However, such is the demand for this safe version of baby milk that the global response has been to place restrictions on it. Essentially, we are seeing a system of rationing emerging.

Hong Kong was the first government to limit the amount bought to two cans of formula per day, with the potential for a fine of over $64,000 and up to two years in prison for those who do not abide by the rules. The UK has now also responded with restrictions on the quantity that can be purchased and other countries may follow suit if the excess demand continues.

According to Sainsburys:

As a short-term measure, retailers including Sainsbury’s are limiting the amount of baby milk powder that people can buy. In this way we aim to ensure a constant supply for our customers and we therefore hope they won’t be inconvenienced.

The Chinese government has reacted to this and is aiming to restore confidence in the food industry, but as yet there has been little positive effect and until there are 100% guarantees of food safety the surge in demand for baby formula from abroad is likely to continue.

This policy of rationing is clearly not only going to affect Chinese parents looking to import baby formula, but is already having an impact on domestic residents. Parents living in the UK are feeling the rationing effects and are also being restricted in terms of how many cans of formula they can buy per day. For many families this isn’t a problem, but for those with multiple children and for whom a trip to the supermarket is not a simple task, the restrictions on baby milk purchases is likely to become a problem. The following articles consider this topic.

The UK economy faces a growing problem of energy supplies as energy demand continues to rise and as old power stations come to the end of their lives. In fact some 10% of the UK’s electricity generation capacity will be shut down this month.

Energy prices have risen substantially over the past few years and are set to rise further. Partly this is the result of rising global gas prices.

In 2012, the response to soaring gas prices was to cut gas’s share of generation from 39.9% per cent to 27.5%. Coal’s share of generation increased from 29.5% to 39.3%, its highest share since 1996 (see The Department of Energy and Climate Change’s Energy trends section 5: electricity). But with old coal-fired power stations closing down and with the need to produce a greater proportion of energy from renewables, this trend cannot continue.

But new renewable sources, such as wind and solar, take a time to construct. New nuclear takes much longer (see the News Item, Going nuclear). And electricity from these low-carbon sources, after taking construction costs into account, is much more expensive to produce than electricity from coal-fired power stations.

So how will the change in balance between demand and supply affect prices and the security of supply in the coming years. Will we all have to get used to paying much more for electricity? Do we increasingly run the risk of the lights going out? The following video explores these issues.

In the blog No accounting for trade, the rise in the UK’s balance of trade deficit was discussed. Many factors have contributed to this weakening position and no one market is to blame. But, by analysing one product and thinking about the factors that have caused its export volumes to decline, we can begin to create a picture not just of the UK economy (or more particularly Scotland!), but of the wider global economy.

Scotch whisky may not have been the drink of choice for many British adults, but look outside Great Britain and the volume consumed is quite staggering. For example, French consumers drink more Scotch whisky in one month than they drink cognac in one year. The volume of Scotch whisky exported from our shores was £4.23 billion for 2011, accounting for 90% of all sales and making its way into 200 markets. However, one problem with this product is that it is highly susceptible to the business cycle. Add to this the time required to produce the perfect Scotch (in particular the fact that it must be left to mature) and we have a market where forecasting is a nightmare.

Producers typically look to forecast demand some 10 years ahead and so getting it right is not always easy, especially when the global economy declines following a financial crisis! So what has been the impact on exports of this luxurious drink? In the past few years, it has been as key growth market for UK exports rising by 190% in value over the past decade. But in 2012 the volume of Scotch whisky exports fell by 5% to 1.19 billion bottles. What explains the decline in sales?

The biggest importer of Scotch whisky is France and its volumes were down by 25%. Part of this decline is undoubtedly the economic situation. When incomes decline, demand for normal goods also falls. Many would suggest Scotch whisky is a luxury and thus we would expect to see a relatively large decline following any given fall in income. However, another factor adding to this decline in 2012 is the increased whisky tax imposed by the French government. Rising by 15% in 2012, commentators suggest that this caused imports of Scotch whisky to rise in 2011 to avoid this tax, thus imports in 2012 took a dive. Spain is another key export market and its economic troubles are clearly a crucial factor in explaining their 20% drop in volume of Scotch whisky imported.

But, it’s not all bad news: sales to Western Europe may be down, but Eastern Europe and other growth countries/continents, such as the BRICs and Africa have developed a taste for this iconic product. Latvia and Estonia’s value of Scotch whisky imports were up by 48% and 28% respectively, as Russian demand rises and China, still growing, is another key market. Gavin Hewitt, chief executive of the Scotch Whisky Association said:

A combination of successful trade negotations, excellent marketing by producers, growing demand from mature markets, particularly the USA, and the growing middle class in emerging economies helped exports hit a record £4.3bn last year.

Furthermore, while the volume of exports worldwide did fall, the value of these exports rose to £4.27 billion, a growth of 1%. This suggests that although we are exporting fewer bottles, the bottles that we are exporting are more expensive ones. Clearly some people have not felt the impact of the recession. For Scotland and the wider UK, these declining figures are concerning, but given the cyclical nature of the demand, as the world economy slowly begins to recover, sales are likely to follow suit. Gavin Hewitt continued his comments above, saying:

We are contributing massively to the Government’s wish for an export-led recovery. There is confidence in the future of the industry, illustrated by the £2bn capital investment that Scotch whisky producers have committed over the next three to four years.

VAT was introduced on the 1st of April 1973, as part of the conditions for the UK entering the Common Market. Designed by a French tax expert, Maurice Lauré, it was initially envisaged as a straightforward replacement for purchase tax, which would be applied to most goods and services.

Forty years on, VAT is increasingly complex, with numerous exemptions, many anomalies in its scope, and increasingly expensive challenges to its imposition. How did we get to this point? And is it time for VAT to undergo a mid-life makeover?

All governments have to raise taxes – to redistribute income and to fund public spending. They have a number of mechanisms they can use, but essentially they have to tax incomes (direct taxes), spending (indirect taxes) or a mix of both. The main indirect tax in the UK is VAT, which now raises over £100bn a year, compared with £1.5bn in its first year (see above chart: click here for a PowerPoint version). Initially envisaged as a simple, cross-Europe purchase tax, the current system is complex and at times appears to have been formulated ‘on the hoof’, never a good way to build a tax system.

In the 2012 Budget, the Chancellor decided to apply the standard rate of income tax to hot takeaway pasties; previously they had been zero-rated. However, he had sharply underestimated the ability of the industry to lobby against the tax, working closely with the tabloid press. Perhaps more importantly, he also missed the complex nature of the good; when is a hot pasty just cooling down? And what is hot? The government backtracked and now 20% VAT is only charged on pasties that are deliberately kept hot. You might think that this change of heart avoided introducing an anomaly, but consider how you might feel if you sell takeaway baked potatoes, which are subject to VAT.

Apart from the complexity of the system, VAT is unpopular with some commentators who feel that it falls too heavily on low-income households. Although many foodstuffs are zero-rated and housing is exempt, VAT is charged at 20% on clothing and many necessities such as cleaning materials. Gas and electricity are subject to a reduced rate of 5% and both alcohol and cigarettes have additonal excise duties imposed and yet are disproportionally consumed by the poor. When the standard rate of VAT was temporarily dropped to 15% in 2010, but then permanently raised to 20% in 2011, many felt that this was a shift in the tax burden to the poor.

So complex, irrational and prone to changes following political lobbying or expensive legal cases, VAT does seem to be stumbling into its forties under something of a cloud. However, it remains the case that it raises a large proportion of UK tax revenues at relatively low direct cost and provides the Chancellor with a reasonably effective fiscal policy tool. Even if a government wanted to put in place an alternative, it is likely that the associated political risks would be too high for it to do so. We might hope for some rationalisation of the current system, but there is little doubt that we will be raising a glass to VAT’s 50th birthday in 2023.

Questions

  1. Explain why VAT might be deemed regressive. Can you formulate an argument that it falls more heavily on the rich than the poor?
  2. Why is VAT administratively cheap? Other than generating tax revenues, can you think of any advantages of the tax?
  3. Newspapers and books are zero-rated in the UK, while e-books and news apps are standard rated at 20%. Can you identify some other anomalies in the UK VAT system? Is there an argument that a better approach would be to charge a lower rate on all goods and services?
  4. Who pays VAT, consumers or producers? Illustrate your answer with a diagram, or two.
  5. A business has to register for VAT once it has a turnover of £77,000 pa. Does this system give rise to any perverse incentives?
  6. Countries across the European Union have varying VAT rates, applied to very different ranges of products. Explain why this might hinder the workings of a single European market.
  7. Imagine you were running a brand new economy; would you use a value-added tax to raise revenues? What are the alternatives open to governments?

House prices have long been an obsession with the UK media and much of the public; when they rise, homeowners feel rich, when they fall, consumer confidence dives. Following the financial crisis and subsequent recession, there has been a great deal of attention focused on the overall health of the housing market.

But the UK faces a particular problem of a sharp and growing divide in regional house prices. First time buyers in London face having to find high deposits and even then, many are unable to access mortgages. Meanwhile those in the regions can access more affordable housing, but may be reluctant to enter the market when prices are stagnant. What are the implications of this divide for the housing market and for the broader economy?

The housing market demonstrates characteristics which are typical of those for goods that are both consumable and involve capital growth; when prices rise housing is seen as a good ‘investment’ and demand increases, this in turn leads to higher prices. Conversely when values drop, demand falls and the market slumps. Markets like this are described as being prone to price bubbles.

Looking at UK house prices as a whole can, however, mask large variations across the economy; variations which can cause problems for jobseekers, for employers and for the government. Recently one of the UK’s largest mortgage lenders predicted continuing regional variance in house prices. Halifax’s figures looked at the price of housing across a number of UK towns and showed that changes seen during 2012 ranged from a 14.8 per cent rise to an 18.4 per cent fall. The biggest rise seen during the year was in Southend on Sea, in Essex, while the greatest fall was in Craigavon, in Northern Ireland. Of the ten towns with the biggest rises, eight were found in London or the south east, with Durham being the only northern town showing growth. Of the ten towns that the Halifax identified with the biggest falls, four are in Scotland, three are in the north west, one is in the north of England and one is in Northern Ireland.

Martin Ellis, housing economist at the Halifax, said:

We expect continuing broad stability in house prices nationally in 2013. The generalised north/south divide in house price performance seen during 2012 is likely to continue next year. House prices are expected to be strongest in London and the south east as this part of the country performs best in economic terms.

These disparities present a particular problem in a recession. While London and the south east show signs of economic growth, with relatively low unemployment and high levels of inward investment, many regions outside London see house prices falling further as unemployment grows. There are some exceptions – the arrival of the BBC in Salford has resulted in a sharp increase in prices there – but, in general, confidence is low outside the south east.
