In many parts of the world, life in the oceans is dying out. The term ‘dead zones’ is used to describe seas that are devoid of marine life. And these zones are growing in size and number.
It’s not just the decline in fish and other marine species that’s worrying environmentalists and many others; it’s a growth in rubbish. Part of this is caused by natural disasters, such as the 2011 Tsunami in Japan that washed huge amounts of debris into the Pacific Ocean. But much of it is caused by rubbish carried down rivers and into the seas, or rubbish jettisoned from ships. The problem is particularly acute in areas of the oceans where currents circulate the rubbish into huge rubbish dumps. There are two such areas either side of Hawaii in the Pacific. Both are vast.
The first article below tells the tale of Newcastle (Australia) yachtsman Ivan Macfadyen. He completed the 2013 Melbourne to Osaka double handed yacht race earlier this year as skipper of his yacht Funnelweb and then went on to bring the yacht home to Australia via America and race the famous Trans-Pac Yacht Race from Los Angeles to Hawaii along the way.
Exactly 10 years before, when [he] had sailed exactly the same course from Melbourne to Osaka, all he’d had to do to catch a fish from the ocean between Brisbane and Japan was throw out a baited line.
“There was not one of the 28 days on that portion of the trip when we didn’t catch a good-sized fish to cook up and eat with some rice,” Macfadyen recalled. But this time, on that whole long leg of sea journey, the total catch was two. No fish. No birds. Hardly a sign of life at all.
After reaching Osaka in Japan, they sailed on to San Francisco via Hawaii.
“After we left Japan, it felt as if the ocean itself was dead,” Macfadyen said. “We hardly saw any living things. We saw one whale, sort of rolling helplessly on the surface with what looked like a big tumour on its head. It was pretty sickening.”
“I’ve done a lot of miles on the ocean in my life and I’m used to seeing turtles, dolphins, sharks and big flurries of feeding birds. But this time, for 3000 nautical miles there was nothing alive to be seen.”
In place of the missing life was garbage in astounding volumes.
As economists, you should readily understand that here we have a case of over-exploited common resources – a Tragedy of the Commons of epic proportions. One ship’s rubbish may make a tiny difference, but when the cost of dumping is near zero and when the oceans are not policed, what is rational for a single ship becomes a disaster when repeated tens of thousands of times by other ships
Again, overfishing is the result of seemingly rational behaviour by crews of individual fishing boats. But as Economics (8th edition) points out on pages 328–30:
Common resources are not owned but are available free of charge to anyone. Examples include the air we breathe and the oceans for fishing. Like public goods, they are non-excludable. For example, fishing boats can take as many fish as they are able from the open seas. There is no ‘owner’ of the fish to stop them. As long as there are plentiful stocks of fish, there is no problem.
But as more people fish the seas, so fish stocks are likely to run down. This is where common resources differ from public goods. There is rivalry. One person’s use of a common resource diminishes the amount available for others. This result is an overuse of common resources. This is why fish stocks in many parts of the world are severely depleted, why virgin forests are disappearing (cut down for timber or firewood), why many roads are so congested and why the atmosphere is becoming so polluted (being used as a common ‘dump’ for emissions). In each case, a resource that is freely available is overused. This has become known as the tragedy of the commons.
… When I use a common resource, I am reducing the amount available for others. I am imposing a cost on other people: an external cost. If I am motivated purely by self-interest, I will not take these external costs into account.
Try doing some research to find out just what has been happening to the state of the oceans in recent years.

First the good news. Employment is rising and unemployment is falling. Both claimant count rates and Labour Force Survey rates are down. Compared with a year ago, employment is up 279,092 to 29,869,489; LFS unemployment is down from 7.87% to 7.69%; and the claimant count rate is down from 4.7% to 4.0%.
Now the bad news. Even though more people are in employment, real wages have fallen. In other words, nominal wages have risen less fast than prices. Since 2009, real wages have fallen by 7.6% and
have continued to fall throughout this period. The first chart illustrates this. It shows average weekly wage rates in 2005 prices. (Click here for a PowerPoint of the chart.)
The fall in real wages is an average for the whole country. Many people, especially those on low incomes, have seen their real wages fall much faster than the average. For many there is a real ‘cost of living’ crisis.
But why have real wages fallen despite the rise in employment? The answer is that output per hour worked has declined. This is illustrated in the second chart, which compares UK output per worker with that of other G7 countries. UK productivity has fallen both absolutely and relative to other G7 countries, most of which have had higher rates of investment.
The falling productivity in the UK requires more people to be employed to produce the same level of output. Part of what seems to be happening is that many employers have been prepared to keep workers on in return for lower real wages, even if demand from their customers is falling. And many workers have been prepared to accept real wage cuts in return for keeping their jobs.
Another part of the explanation is that the jobs that have been created have been largely in low-skilled, low-wage sectors of the economy, such as retailing and other parts of the service sector.
But falling productivity is only part of the reason for falling real wages. The other part is rising prices. A number of factors have contributed to this. These include a depreciation of the exchange rate back in 2008, the effects of which took some time to filter through into higher prices in the shops; a large rise in various commodity prices; and a rise in VAT and various other administered prices.
So what is the answer to falling real wages? The articles below consider the problem and some of the possible policy alternatives.

You may have been following the posts on the US debt ceiling and budget crisis: Over the cliff and Over the cliff: an update. Well, after considerable brinkmanship over the past couple of weeks, and with the government in partial shutdown since 1 October thanks to no budget being passed, a deal was finally agreed by both Houses of Congress, less than 12 hours before the deadline of 17 October. This is the date when the USA would have bumped up against the debt ceiling of $16.699 trillion and would be in default – unable to borrow sufficient funds to pay its bills, including maturing debt.
But the deal only delays the problem of a deeply divided Congress, with the Republican majority on the House of Representatives only willing to make a long-term agreement in exchange for concessions by President Obama and the Democrats on the healthcare reform legislation. All that has been agreed is to suspend the debt ceiling until 7 February 2014 and fund government until 15 January 2014.
A more permanent solution is clearly needed: not just one that raises the debt ceiling before the next deadline, but one which avoids such problems in the future. Such concerns were echoed by Christine Lagarde, Managing Director of the International Monetary Fund (IMF), who issued the following statement:
The U.S. Congress has taken an important and necessary step by ending the partial shutdown of the federal government and lifting the debt ceiling, which enables the government to continue its operations without disruption for the next few months while budget negotiations continue to unfold.
It will be essential to reduce uncertainty surrounding the conduct of fiscal policy by raising the debt limit in a more durable manner. We also continue to encourage the U.S. to approve a budget for 2014 and replace the sequester with gradually phased-in measures that would not harm the recovery, and to adopt a balanced and comprehensive medium-term fiscal plan.

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.
