Economics studies the choices people make. ‘Rational choice’ involves the weighing up of costs and benefits and trying to maximise the surplus of benefits over costs. This surplus will be maximised when people do more of things where the marginal benefit exceeds the marginal cost and less of things where the marginal cost exceeds the marginal benefit. But, of course, measuring benefits and costs is not always easy. Nevertheless, for much of the time we do make conscious choices where we consider that choosing to do something is ‘worth it’: i.e. that the benefit to us exceeds the cost.
When we make a choice, often this involves expenditure. For example, when we choose to buy an item in a shop, we spend money on the item, and also, perhaps, spend money on transport to get us to the shop. But the full opportunity cost includes not only the money we spend, but also the best alternative activity sacrificed while we are out shopping.
Then there are the benefits. Not all pleasurable activity costs us money. The sight of beautiful contryside or the pleasure of the company of friends may cost us very little, if anything, in money terms. But they may still be very valuable to us.
If we are to make optimal decisions we need to have some estimate of all costs and benefits, not just ones involving the payment or receipt of money. This applies both to individual behaviour and to collective decisions made by governments or other agencies.
Cost–benefit analysis seeks to do this to help decisions about new projects, such as a new road, a new hospital, environmental projects, and so on. But just how do we set about putting a value on the environment – on the pleasure of a walk in bluebell woods, on protecting bird life in wetlands or sustaining ecosystems?
For the first time there has been a major study that attempts to value the environment. According to the introduction to the report:
The UK National Ecosystem Assessment (UK NEA) is the first analysis of the UK’s natural environment in terms of the benefits it provides to society and the nation’s continuing prosperity. Carried out between mid-2009 and mid-2011, the UK NEA has been a wide-ranging, multi-stakeholder, cross-disciplinary process, designed to provide a comprehensive picture of past, present and possible future trends in ecosystem services and their values; it is underpinned by the best available evidence and the most up-to-date conceptual thinking and analytical tools. The UK NEA is innovative in scale, scope and methodology, and has involved more than 500 natural scientists, economists, social scientists and other stakeholders from government, academic and private sector institutions, and non-governmental organisations (NGOs).
The following podcast and webcast look at the report and at some of the issues it raises in terms of quantifying and incorporating environmental costs and benefits into decision taking.

$8 billion – this is the likely cost of the BP oil leak, which spilled 206 million gallons of oil into the Gulf of Mexico. Whilst the oil leak has been stopped for some time, there were ongoing concerns that the leak would re-appear due to the underwater pressure. The cost of stopping the leak has been substantial, but BP will face further costs, as the company begins to pay out compensation.
$20 billion is the compensation that residents of the Gulf of Mexico will receive. Further to this, BP has said that it will invest more money in promoting the tourism industry there, which has suffered from the oil spill. However, what about the fishing industry? Although compensation will be paid for the losses incurred, will this continue in the long term? The oil may cause a loss in productivity in certain populations of sea-life. How will this impact us? If certain fish became scarcer, then their price will rise accordingly, whether you purchase the fish at a shop or have it as a meal in a restaurant. To make matters worse, the hurricane season has arrived in the affected areas, which will make the clean-up effort even harder.
As BP’s share price has fallen, individuals have suffered from lower dividends. Jupiter Income Trust had almost 10% of their portfolio invested in BP, which largely explains the 9 per cent drop in their payout.

Whenever a sporting event comes around, there is mad frenzy from countries across the world to enter a bid – this was entirely evident with the 2018 World Cup bids! And it’s not really surprising with the attention that the World Cup and the Olympics receive. Hundreds of thousands of spectators, billions of pounds worth of investment in infrastructure, thousands of jobs created and television deals in every country of the world.
However, why is it that every sporting event of this magnitude fails to come in on budget? The costs are always underestimated. The Athens Olympics was supposed to cost £1.5 billion, but ended up costing over 10 times as much. It is also suggested that it may have played a part in the current Greek financial crisis. The 2002 Japanese World Cup had little effect on the struggling Japanese economy. The London 2012 Olympics was estimated to cost £2.35 billion, but suggestions say it will now cost taxpayers some £20 billion, although budget cuts are inevitable. What about South Africa? Costs of $300 million were estimated for stadiums and infrastructure, with a boost to GDP of $2.9 billion. However, $300 million was not even sufficient to renovate Soccer City (where the first and final game will be held). Add on to this over $1 billion to rebuild the rest of the stadiums and then take into account rising inflation, which has caused inevitable cost over-runs.
On top of this, every country says ‘look at the benefits’ when they enter their bid. However, economists have suggested that there are actually minimal employment benefits in the long term. Obviously there is substantial investment in infrastructure leading up to the World Cup, which will benefit locals, but the overall boost to GDP is not expected to be significant. A similar thing can be seen with the London Olympics. In the study by PriceWaterhouseCoopers in 2005, there were estimates of a direct gain to London’s GDP of £5900 million between 2005 and 2016. However, UK GDP would only rise by £1936 million. Some of the costly stadiums that were built for the Portuguese European Championships were simply knocked down after the event.
So, what can we expect from South Africa? There have been many criticisms of poor ticket sales and that this World Cup is only for the rich. Street sellers have been booted out of their normal selling ground, as they do not have the necessary permits to sell and cannot afford to buy the permits anyway. Whilst transport has been improved, there are still concerns about the distance that has to be travelled between stadiums and this has put off many potential spectators. However, the Super 14 Southern Hemisphere Rugby tournament was staged in South Africa, with the final at the end of May and the event was successful. Transport worked perfectly, spectators arrived by the thousand and it is hoped that this is a positive omen for the fast approaching World Cup!

As the news from the Gulf of Mexico goes from very bad to even worse, so BP is increasingly coming under the international spotlight for its approach to risk management and safety. Was it sufficiently cautious? Could the accident on April 20 that killed 11 men and has been gushing some 800,000 gallons per day of crude oil into the sea have been averted? When the consequences of a pipe rupture are so catastrophic, is ‘catastrophic risk’ appropriately priced? As Tony Hayward, BP’s Chief Executive, told the Financial Times (see links below): “It was ‘an entirely fair criticism’ to say the company had not been fully prepared for a deep-water oil leak.”
One insight into BP’s approach to risk has come to light with the leaking of a 2002 memo from BP on how human life ought to be valued in any cost–benefit analysis of a project. As the Chicagoist summarises the memo:
A two page document prepared by risk managers in 2002 titled “Cost benefit analysis of three little pigs” shows the type of thinking BP put into risk assessment. The memo shows, in cartoonish fashion, that blast resistant trailers for BP’s workers weren’t necessary, because the cost was too high. In 2005, a refinery caught fire, killing 15 and injuring 170 people.
So how should catastrophic risk be taken into account? What does a company do when the probability of a disaster is extremely low and yet the costs of such a disaster, were it to occur, are extremely high?

Russia is now ranked alongside Zimbabwe on the worldwide corruption index, despite the fact that the Russian authorities have been doing their best to tackle it. The Russian bribery ‘industry’ is worth some $300 billion per year and those who can be bought include several government officials.
The Russian economy is in much need of foreign investment, but the growing world of bribery is deterring international businesses from investing in Russia. Not only will they face the costs of building and running the business, but they are also likely to face substantial costs in trying to get the paperwork through, as IKEA found. Having said that they would never resort to bribery, IKEA had to pay $4 million for investment in local infrastructure and donate a further $1 million for local government projects just to get the 300+ permits they needed to begin construction. This then led to further bribes and a number of lawsuits. For some companies, the delays caused by not paying a bribe may actually cost more than the bribe itself.
The following webcast and articles look at the case of IKEA and the push by foreign businesses to avoid the clutches of Russian bribery.
