A simple model in economics is that of demand and supply. Through the price mechanism, signals are sent between consumers and producers and this interaction results in an equilibrium market price and quantity. However, what happens when the market for a good or service is in disequilibrium?
When a market is in equilibrium, demand equals supply. However, as we discussed in a previous blog concerning baby milk in China (see Milking the economy), markets are not always in equilibrium. If demand exceeds supply, a shortage will emerge and to eliminate this, the price must rise. If, on the other hand, supply exceeds demand, there will be an excess supply and thus the price must fall to restore equilibrium.
The market in question here is toilet paper in Venezuela! A severe shortage of this product has emerged in recent months, with shops running out of supplies. In a bid to relieve this shortage, the country’s Minister of Commerce has received approval for a $79 million credit, which can be used to import this basic product in short supply. Fifty million rolls will be imported to help fill the shortage that has emerged. The shortage is not just a problem for toilet paper, but also across a range of basic consumer goods. The article from Reuters comments that:
The government says the toilet paper shortages, like others, are the results of panicked buying and unscrupulous merchants hoarding the goods to artificially inflate prices.
Opposition critics say the problem is caused by the currency controls, created a decade ago by late socialist leader Hugo Chavez, and years of nationalizations that weakened private industry and left businesses unwilling to invest.
With shortages across a variety of products, the President has begun to work closely with business leaders to address this situation. The following articles consider this basic market, the intervention and consequences.

Imagine that the team you support has made the final of a major competition or a your favourite band is playing a live concert this summer. You desperately want a ticket and are willing to pay the advertised price. They go on sale at 9.00am in the morning and you go on-line at 8.59am but unfortunately the webpage will not load. You keep pressing the refresh button but with no success. Eventually, annoyed and frustrated, you give up at 10.00am!
Tickets for sporting, musical or other live shows are initially sold by people who organise the events in two ways. They may choose to sell some or all of the tickets directly to the customer. For example you can buy tickets for a West End show from the box office in the theatre. With some football games it is still possible to buy tickets on the day at the stadium. Another approach is to sell some or all of the tickets via an authorised ticket agent. These businesses are usually members of STAR (The Society of Ticket Agents and Retailers) and the organisers of the sporting, musical or live show provide them with tickets to sell on their behalf. Some of the larger and well known agents such as Ticketmaster, Ticketline and Seetickets usually sell the tickets at face value although some booking fees are often added to the price. This initial sale of tickets by either the event organiser themselves or an agent acting on their behalf is referred to as the primary market.
For example, British Athletics sold all of its 130,000 tickets for its two day Anniversary Games on the 26th and 27th July via its authorised ticket agent in 75 minutes!! However an internet search for this event will quickly reveal that tickets are still available!! Unfortunately in most cases the advertised price will be far greater than the face value of the ticket. How is this possible? The answer is that the internet has helped a thriving secondary market for tickets to develop. The secondary market refers to situations where people who have already purchased tickets through the primary market re-sell them to other members of the public. Prior to the internet the main way of buying a ticket in the secondary market was to visit the venue on the day of the event and hunt for some-one willing to sell. However technology has dramatically reduced these transaction costs and made it much easier for potential buyers and sellers to make an exchange. For example companies such as Viagogo, Seatwave, GetMeIn and Stubhub have created websites that allow members of the public to buy and sell tickets. As Viagogo publish on their webpage:
You are buying tickets from a third party, Viagogo is not the ticket seller. Ticket prices are set by the seller and may be above or below face value.
Why does this secondary market exist? An economist would argue that it can only happen if the quantity of tickets demanded is greater than the quantity of tickets for sale at the price set by the event organiser. If this was not the case then customers would be able to buy tickets through the primary market on the day of the match, concert or show. The puzzle is to explain why prices do not rise in the primary market. If the quantity demanded of any product is greater than the quantity supplied then market forces should put upward pressure on prices. However it would appear that many of the event organisers appear to resist this incentive and consistently set prices below the level that would limit demand to the number of tickets available. This leaves an opportunity for sellers in the secondary market to sell tickets much closer to their market clearing rate. Navin Kekane, the business operations director of Stubhub, stated that
What we do is all about supply and demand, and you can sometimes find tickets at below face value.
Some of these companies in the secondary market have recently established formal partnerships with a number of English Premier League (EPL) football clubs and other major sporting bodies. For example Viagogo have signed deals with 10 EPL clubs while Stubhub have deals with 3 EPL clubs as well as Leicester Tigers and the Lawn Tennis Association.
However some observers have expressed grave reservations about the growth of the secondary market. For example Malcolm Clarke, chairman of the Football Supporters Federation, stated that
At the moment if you are fan trying to sell a spare ticket and are not authorised to do so then you face a criminal conviction, even if you sell at the face value.
But secondary ticketing exchanges, because they are authorised, are allowed to do so. Many clubs grant these agencies the right to allow the re-sale of tickets for their matches at above face value. I don’t think that can be right.
Joe Cohen, the founder of Seatwave counters that
Touts is an emotional, dehumanising word. The reality is that they are just speculators. No one likes speculators until you need something from them.
Some have called for more regulation of the secondary market. For example Sharon Hodgson, Labour MP for Washington and Sunderland West, unsuccessfully tried to get a Private Members Bill through Parliament which would have made it illegal to re-sell tickets for more than 10% above their face value.

Why are 43 companies in the pub and restaurant sector in the UK donating over a £1 million to an 86 year old Frenchman who claims to work a 70 hour week? Jacques Borel has led an interesting and varied life which has included activities such as helping the French resistance in the 2nd world war and opening the first take-away hamburger restaurant in France in 1961. In 2001 he started a campaign to get the European Union to allow member states to reduce the rate of VAT applied to food and drink sold in the pub, hotel and restaurant industry. Organisations such as JD Wetherspoon, Heineken and Pizza Hut are backing his attempts to persuade the UK government of the benefits of this policy.
VAT is paid when goods and services are purchased and is normally included in the price advertised by the seller. It generates a significant amount of money for the UK government and it is estimated that it will raise £102 billion in 2012-13 – the third biggest source of revenue after income tax and national insurance contributions. It is applied at three different rates in the UK – a standard rate of 20%, a reduced rate of 5% and a zero rate i.e. 0%. This may sound straightforward but in reality the tax is extremely complicated as previously discussed in articles on this website . For example most basic or staple items of food sold in shops are zero rated. However there are some rather bizarre exceptions. For example a packet of potato crisps is subject to the standard rate of VAT whereas tortilla chips are not. The standard rate is applied to a packet of Wotsits whereas a zero rate is applied to a packet of Skips!
The campaign headed by Mr Borel focuses on the discrepancy between the zero-rate applied to most food items purchased from a shop and the standard rate applied to food purchased in restaurants or cafes. For example, if you buy a Pizza from a supermarket then you don’t pay any tax on this purchase, whereas if you eat a pizza in a restaurant the standard 20% rate of VAT is applied. Mr Borel is lobbying the UK government to reduce the rate of VAT paid in pubs and restaurants from the standard rate of 20% to the reduced rate of 5%. One reason why so many UK companies are willing to offer him financial support is because of his success in getting governments in other countries such as Germany, Belgium, Finland and France to adopt this policy.
In a recent radio interview Mr Borel was asked to make his case for the proposed reduction of VAT in the UK. He claimed:
I have a commitment from 125 chains of hotels, restaurants and independents to use 60% of the reduction in VAT to lower prices so that would be a 7.5% decrease in price. When you decrease price by that magnitude you will see an increase in customers of 10-12% and you will be forced to hire new staff. In our best case scenario, we plan to create 670,000 jobs in three years.
When asked in another interview why the hospitality sector should be favoured more than others he replied that:
It would create more jobs in a minimal amount of time…you cannot do that with any other industry.
One obvious drawback of the policy would be the loss of revenue for the UK government. Some estimates have suggested that the loss of VAT receipts would be between £5.5 and £7.8 billion. However it has been claimed that over time the impact of the change on government finances would be zero. In response to the proposed tax cut a Treasury spokesman commented:
Any reduced rates would make a significant impact on revenue and, as a significant proportion of spending in these areas is by UK residents, any increase in activity in these areas would largely be at the expense of other consumer spending.

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.
