Your favourite chocolate bar or your drink of hot chocolate could soon be much dearer. Since March, the price of cocoa has risen by 34% and much of this increase remains to be passed on to the consumer. The price of cocoa butter is up 70% since the beginning of the year.

On the demand side, sales of luxury cocoa-rich chocolate and hot chocolate have been rising and chocolate manufacturers, with relatively low forward purchases of cocoa, are likely to have to buy more in spot markets. What is more, there is growing speculative demand as traders anticipate higher prices to come.

On the supply side, dry weather in West Africa, where 70% of cocoa beans are produced, has led to a fall in output. Estimates suggest that cocoa production in the 12 months to end-September 2013 will be 2.7% down on the previous 12 months. Supply is expected to be 60,000 tonnes less than demand, resulting in a fall in stocks from 1,833,000 to 1,773,000.

The following articles look at the ‘crisis’ for chocoholics and at the market conditions that lie behind it.

Over the past few years lobster prices in Maine have tumbled. Eight years ago the price paid to fishermen was around $4.60 per pound. Today it’s around $2.20. The problem is one of booming lobster populations and the dominance of lobster in catches. Last year’s haul was double that of a decade ago and, in some waters, six times higher.

You would think that larger catches would be good news for fishermen. But prices now are so low that they barely cover variable costs. Individual fishermen fish harder and longer to bring in even bigger catches to make up for the lower price. This, of course, compounds the problem and pushes the price even lower.

So what are the answers for the fishermen of Maine? One solution is to diversify their catch, but with lobster so plentiful and other fish stocks depleted, this is not easy.

Another solution is to cooperate. The Reuters article below quotes John Jordan, a lobsterman and president of Calendar Islands Maine Lobster Co.:

‘If you had an industry that actually cooperated, you wouldn’t be bringing in more product if you couldn’t sell what you already had, right?’

Restricting the catch would require lobster distributors to cooperate and set quotas for what the fishermen would be permitted to sell. But with over 5000 fishermen, this is not easy.

Another solution is to expand the market. One way is for the distributors or other agencies to market lobster and lobster products more aggressively. For example, this year the State of Maine has established a $2 million marketing collaborative. Another solution is to find new markets.

Jordan’s company and others are frantically seeking new ways to sneak lobster into unexpected corners of the food market, from gazpacho to puff pastries and quiche.

In the meantime, for consumers the question is whether the low prices paid to the fishermen of Maine will feed through into low prices in the fishmonger, supermarket and restaurant. So far that does not seem to be happening, as the final two articles below explain.

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.

Increases in the cost of living over the past few years have put many families under financial pressure. One of the main factors that has been hurting households is the price of petrol and diesel. Road fuel duty was due to be increased last August, but the Chancellor delayed it in June. However, a planned 3p rise in duty by the Coalition, which has faced rebellion from numerous MPs may now be delayed further, following a hint from the Treasury.

The government has said that it will do everything it can to support struggling families with the cost of living and this has led many to conclude that in the Autumn Statement, the Chancellor will delay the planned 3p rise. Labour was defeated in its efforts to force a delay of the proposed 3p duty rise, as Tory bankbenchers were given this hint that the Treasury would decide to delay the increase anyway. The Economic Secretary to the Treasury said that fuel duty is part of the government’s strategy to help cut the cost of living. He commented that fuel duty was 20% lower in real terms compared to March 2000, when it was at its peak.

If we had continued with the policies of the previous government, quite simply prices would be higher, fuel would be 10p more expensive per litre. I know some will call for a further freeze in fuel duty today. I can assure them this government understands the financial pressures hard-working families are facing. Subject to the constraints of the public finances, this government is determined to help families with the cost of living.

A key economic question to consider is why is fuel one of the products that is frequently taxed? When a tax is imposed on a product, its price will rise and as the law of demand tells us, this will cause people to purchase less of it. But, what is so special about petrol? Why do people continue to purchase petrol even when its price rises? The following articles consider the concerns surrounding the 3p fuel duty rise.

The problem of obesity and healthy eating is a growing problem in many countries and governments have long been looking into designing policy to tackle this issue.

Some have gone for healthy eating campaigns and policies to encourage pregnant women to eat better, but one government took it a step further and introduced a Fat Tax. In October 2011, the Danish government introduced a tax on foods that are high in saturated fat in a bid to reduce consumption of these goods. However, this policy is now to be abolished.

The Fat Tax introduced by the government imposed a surcharge on foods that contained more than 2.3% saturated fat. Numerous products were affected, including meats, dairy and as expected – processed foods. The policy was criticised by scientists who said that saturated fat was the wrong target and perhaps they were proved right, but the government’s u-turn, which will now see the tax being abolished. The tax had gradually increased food prices throughout the country and authorities said that it had even put Danish jobs at risk.

With food prices much higher in Denmark with the tax, consumers switched from buying domestically produced goods to crossing the border into Germany and purchasing their cheaper food. This undoubtedly had an adverse effect on the Danish economy, as it represented a cut in consumer expenditure. Perhaps it also helps to explain Germany’s strong economy – it was feeding 2 nations! The Danish tax ministry said:

‘The fat tax and the extension of the chocolate tax — the so-called sugar tax — has been criticised for increasing prices for consumers, increasing companies’ administrative costs and putting Danish jobs at risk … At the same time it is believed that the fat tax has, to a lesser extent, contributed to Danes travelling across the border to make purchases … Against this background, the government and the (far-left) Red Green Party have agreed to abolish the fat tax and cancel the planned sugar tax’

Once the tax is abolished, other policies will need implementing to tackle the problem of obesity and encourage healthy eating, as it continues to be a big problem in this and many other countries. The following articles consider this problem.
