The 2012 London Olympics opened on 27 July. This has been the result of years of planning and investment in infrastructure since London won the bid in 2005.

It is estimated that hosting the Games will have cost over £9bn. It is therefore interesting to consider the long-run impact on a host city years after the last medal has been won. We might expect host cities to achieve increased growth due to the benefits from the improved infrastructure and the impact of increased publicity and exposure on trade, capital and population.

This has recently been investigated in a paper published in the Economic Inquiry by Stephen Billings and James Holladay which looks at the impact hosting the Games has on GDP and trade (working paper available here). One difficulty with trying to identify the impact of hosting the Games, is that only certain cities will have a chance of being chosen as hosts and these may be cities that are more likely to experience future growth. If this is the case, it would appear that the future growth was due to hosting the Games when it would in fact have been likely to occur anyway. In order to control for this, the above paper compares the winners with losing finalists in the selection process for host cities. For example under this approach London would be compared with Singapore, Moscow, New York and Madrid. In addition, subsequent matching processes are also used to select appropriate cities for comparison.

They find that larger cities in wealthier countries are more likely to be chosen to host the Games. However, once comparisons with other appropriate cities are made, overall, they find that hosting the Games has no effect on a cities population, growth or trade. One explanation provided is that the intense competition to host the Games means the potential gains are competed away via escalated promises in order to increase a cities chances of being selected. In addition, they note that there may well still be considerable specific benefits from the investments made to host the Games.

It is also clear that there are both positive and negative externalities from hosting the Games that, whilst difficult to measure, ideally should be taken into account. On the negative side, these include the extra hassle anybody travelling to work in London during the Games will face. On the other hand, on the positive side, it is hoped that part of the long-run legacy of the Games will be increased interest and participation in sport which would result in substantial health benefits.

Academic research is encouraged by universities. Indeed, the number and quality of research publications is the most important criterion for promotion in many universities.

Periodically university research in the UK is publicly assessed. The latest assessment is known as the Research Excellence Framework (REF) and will be completed in 2014. Most research that will be considered by the REF is published in peer-reviewed journals. Most of these journals are subscription based. Universities pay large amounts of money in subscriptions.

In recent years there has been much criticism by both academics and universities about the high cost of such subscriptions. In a movement dubbed the Academic Spring, pressure has mounted for journal articles to be made available free of charge – i.e. on open access.

The government too has been concerned that the results of publicly-funded research has been disappearing behind ‘paywalls’ and hence not available free to people outside the universities which subscribe to such journals. Indeed, no single university can afford licences for all the 25,000 peer-reviewed journals currently being published. As a result, the government set up a committee under the chair of Professor Janet Finch to examine alternative ways of making research more accessible. The committee has just published its report.

It advocates an expansion of open-access journals:

The principle that the results of research that has been publicly funded should be freely accessible in the public domain is a compelling one, and fundamentally unanswerable…

Instead of relying on subscription revenues provided by or on behalf of readers, most [open-access journals] charge a fee to authors…before an article is published. Access for readers is then free of charge, immediately on publication, and with very few restrictions on use and re-use.

Under this model, universities would essentially pay to have their academics’ articles published rather than paying to purchase the journal. Alternatively, research councils could fund the publication of articles based on research already funded by them.

Many people go further. They argue that authors ought to be able to have their published research in any journal made freely available, after an embargo period, through their university’s website.

So is the current pricing model the best for encouraging research and for disseminating its findings? Or is open access a better model – and if so, of what form? Or would it discourage publishers and lead, in the end, to less being published or to a less rigorous peer review process? The questions are ones of pricing, incentives, choices and investment – the questions that economists are qualified to consider.

World leaders have been meeting in Rio de Janeiro at a United Nations Conference on Sustainable Development. The conference, dubbed ‘Rio+20’, refers back to the first UN Conference on Environment and Development (UNCED) held in Rio 20 years ago in June 1992.

The 1992 conference adopted an Agenda 21. It was “comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which human impacts on the environment.”

The 2012 conference has looked at progress, or lack of it, on sustainability and what needs to be done. It has focused on two major themes: “how to build a green economy to achieve sustainable development and lift people out of poverty, including support for developing countries that will allow them to find a green path for development; and how to improve international coordination for sustainable development.” Issues examined have included decent jobs, energy, sustainable cities, food security and sustainable agriculture, water, oceans and disaster readiness.

But just what is meant by sustainable development? The conference defines sustainable development as that which meets the needs of the present without compromising the ability of future generations to meet their own needs. “Seen as the guiding principle for long-term global development, sustainable development consists of three pillars: economic development, social development and environmental protection.”

The articles below look at prospects for national and global sustainability. They also look at a new measure of national wealth, the Inclusive Wealth Index (IWI). This index has been developed under the auspices of the International Human Dimensions Programme on Global Environmental Change (IHDP) and published in its Inclusive Wealth Report 2012 (see report links below).

The IWR 2012 was developed on the notion that current economic production indicators such as gross domestic product (GDP) and the Human Development Index (HDI) are insufficient, as they fail to reflect the state of natural resources or ecological conditions, and focus exclusively on the short term, without indicating whether national policies are sustainable.

The IWR 2012 features an index that measures the wealth of nations by looking into a country’s capital assets, including manufactured, human and natural capital, and its corresponding values: the Inclusive Wealth Index (IWI). Results show changes in inclusive wealth from 1990 to 2008, and include a long-term comparison to GDP for an initial group of 20 countries worldwide, which represent 72% of the world GDP and 56% of the global population. (Click on chart for a larger version.)

So will growth in IWI per capita be a better measure of sustainable development than growth in GDP per capita? The articles also consider this issue.

No market is perfect and when the market mechanism fails to deliver an efficient allocation of resources, we say the market fails and hence there is justification for some government intervention. From a monopolist dominating an industry to a manufacturing firm pumping out pollution, there are countless examples of market failure.

The Guardian is creating a guide to climate change, covering areas from politics to economics. The problem of climate change has been well documented and this blog considers a particular issue – the case for climate change or the environment as a market failure. In many cases just one market failure can be identified, for example an externality or a missing market. However, one of the key problems with climate change is that there are several market failures: externalities in the form of pollution from greenhouse gases; poor information; minimal incentives; the problem of the environment as a common resource and the immobility of factors of production, to name a few. Each contributes towards a misallocation of resources and prevents the welfare of society from being maximised.

When a market fails, intervention is justified and economists argue for a variety of policies to tackle the above failures. In a first-best world, there is only one market failure to tackle, but in the case of the environment, policy must be designed carefully to take into account the fact that there are numerous failings of the free market. Second-best solutions are needed. Furthermore, as the problem of climate change will be felt by everyone, whether in a developed or a developing country, international attention is needed. The two articles below are part of the Guardian’s ultimate climate change guide and consider a huge range of economic issues relating to the problem of environmental market failure.

Questions

  1. What is meant by market failure?
  2. What are the market failures associated with the environment and climate change? In each case, explain how the issue causes an inefficient allocation of resources and thus causes the market to fail? You may find diagrams useful!
  3. What is meant by the first-best and second-best world?
  4. What does a second-best solution aim to do?
  5. Using diagrams to help your explanation, show how a tax on pollution will have an effect in a first best world, where the only market failure is a negative externality and in a second best world, where the firm in question is also a monopolist.
  6. What solutions are there to the problem of climate change? How effective are they likely to be?
  7. Does the need to tackle climate change require international co-operation? Can you use game theory to help your explanation?!

The UK hosted the third Clean Energy Ministerial conference on 25/26 April 2012. More than 20 energy ministers from around the world attended. In his address, David Cameron, gave his backing to more wind farms being built in the UK, both onshore and offshore.

Currently just under 10 per cent of the UK’s electricity is generated from renewable sources. But to meet agreed EU targets this must increse to at least one-third by 2020. Most of this will have to come from wind.

But whilst wind turbines create no CO2 emissions, electricity generated from wind is currently some 15% more expensive than from gas. To make wind power profitable, energy companies are required by law to generate a certain percentage of their electricity from renewables and the cost is passed on to the consumer. This adds some £20 per year to the average household energy bill.

Over the coming years, many new power plants will have to be built to replace the electricity generated from older plants that reach the end of their life. So what types of plant should be built? Unfortunately measuring the costs and benefits from power generation is not easy. For a start, energy needs are not easy to predict. But more importantly, electricity generation involves huge environmental and social externalities. And these are extremely difficult to measure.

What is more, the topic is highly charged politically. The social costs do not fall evenly on the population. People might favour wind turbines, but they do not want to see one outside their window – or from their golf course!

The following videos and articles will give you some insight into the difficulties that any decision makers face in making the ‘right’ decisions about electricity generation
