A bumper harvest should be good news for farmers – but not if it drives down prices. This is the position facing many Australian farmers. After a relatively wet summer a year ago and a mild winter this year, crop yields have soared. But the prices farmers can get in wholesale markets have been so low that many have resorted to setting up their own farm shops or selling in farmers’ markets or from the backs of ‘utes’ (utility vehicles, i.e. pickup trucks) or at roadside stalls.
And the supply problem is not just one of increased domestic supply: cheap food imports, often of inferior quality, have been flooding into Australia. Increasing food exports, 
especially to Asia, would help Australian farmers, but here again there is competition in these markets from other countries.
The problem of increased Australian supply is even more serious for Australian farmers in areas where harvests have not been so good. Australia is a huge country and conditions, although generally favourable this year, have been poor in some areas. Here farmers face the double disaster of low output and low prices.
Australian dairy farmers too are facing problems of falling prices. Price deregulation and the monopsony power of supermarkets have driven down 
the price of milk and other dairy products. Since deregulation in 2000, the number of dairy farms has halved, as many smaller family farms go out of business and larger ‘industrial-scale’ farms grow.
So are there any solutions? The BBC article looks at things being done in Tasmania to help small farmers, but questions whether small farmers have much of a future more generally in Australia?

Demand and supply analysis can be applied to a multitude of markets. When there is a disequilibrium in a market, prices will tend to adjust to eliminate any shortage or surplus. But, what of road space? There is a demand and a supply of road space and when there are too many cars for the road space available, congestion is the consequence.
When an additional car enters the road network, there is a cost and a benefit to the driver. However, there are not only costs/benefits to the driver, but there are also costs/benefits to other road-users. When one car drives on the M25 it adds to the number of cars on the road. Once we reach the point where there are too many cars given the road space and thus the flow of cars per minute begins to fall, congestion starts to build up. There is a negative externality involved here – the actions of one person (the driver) impose an additional cost on other drivers (the congestion). It takes every other road user a little bit of extra time to get from A to B the more cars there are on the road.
Congestion is a problem in many parts of the country and various solutions have been suggested. Policies to reduce demand will help the congestion problem by reducing the number of cars on the road. Numerous strategies have been tried, such as restrictions on parking; improvements in public transport; an integrated transport policy; higher parking charges; work place parking levies; higher taxes on petrol, higher car taxes and congestion charging schemes.
Alternatively, building more roads will directly increase the supply of road space, but this can (and has) simply led to more cars using the additional road space and thus the problem of congestion remains. Bus/taxi lanes are in use across the country and allow the users of public transport to benefit from faster journey times, thus encouraging them to forgo their cars and use buses. However, does this add to the congestion for other people?
In Liverpool, a nine month trial is taking place, where bus lanes will be removed to find out if they have a positive effect on reducing congestion. By increasing the amount of road space available to all road users, Liverpool City Council will be able to see if directly increasing the supply of road space will help to meet the existing demand. The possibility, however, is that by increasing the supply of road space, more individuals will choose to use their cars, thus fuelling demand. Many argue that this trial is a step backwards and will add to congestion, reduce the appeal of travelling by bus and impose further costs on the environment. The following articles consider the debate surrounding congestion.

Questions
- Explain why congestion is a negative externality. What other externalities exist with regard to car usage?
- Using a diagram, show the point at which congestion occurs and explain why there is a difference between the marginal private and marginal social cost.
- What will happen to the difference between the marginal private and social cost curves before and after congestion sets in?
- Think about the different solutions to the problem of congestion. In each case, explain whether it is a demand-side or supply-side solution and how it will aim to combat congestion. You should also consider whether it is a short or long term solution and how feasible it actually is.
- How will the abolition of bus lanes aim to reduce congestion?
- There are supporters for bus lanes and supporters for the abolition of them. Justify the arguments on each side of the debate. You should consider the wider implications as well as the impact on congestion.
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.

The cost of living is a contentious issue and is likely to form a key part of the political debate for the next few years. This debate has been fuelled by the latest announcement by SSE of an average rise in consumer energy bills of 8.2%, meaning that an average dual-fuel customer would see its bill rise by £106. With this increase, the expectation is that the other big energy companies will follow suit with their own price rises.
Energy prices are made up of numerous factors, including wholesale prices, investment in infrastructure and innovation, together with government green energy taxes. SSE has put their price hike down to an increase in wholesale prices, but has also passed part of the blame onto the government by suggesting that the price hikes are required to offset the government’s energy taxes. Will Morris, from SSE said:
We’re sorry we have to do this…We’ve done as much as we could to keep prices down, but the reality is that buying wholesale energy in global markets, delivering it to customers’ homes, and government-imposed levies collected through bills – endorsed by all the major parties – all cost more than they did last year.
The price hike has been met with outrage from customers and the government and has provided Ed Miliband with further ammunition against the Coalition’s policies. However, even this announcement has yet to provide the support for Labour’s plans to freeze energy prices, as discussed in the blog Miliband’s freeze. 
Customers with other energy companies are likely to see similar price rises in the coming months, as SSE’s announcement is only the first of many. A key question is how will the country provide the funding for much needed investment in the energy sector? The funds of the government are certainly not going to be available to provide investment, so the job must pass to the energy companies and in turn the consumers. It is this that is given as a key reason for the price rises.
Investment in the energy infrastructure is essential for the British economy, especially given the lack of investment that we have seen over successive governments – both Labour and Conservative. Furthermore, the government’s green targets are essential and taxation is a key mechanism to meet them. Labour has been criticized for its plans to freeze energy prices, which may jeopardise these targets. The political playing field is always fraught with controversy and it seems that energy prices and thus the cost of living will remain at the centre of it for many months.
