A campaign to introduce a tax on disposable plastic bags in England has been launched by various pressure groups, including The Campaign to Protect Rural England (CPRE), Keep Britain Tidy, the Marine Conservation Society and Surfers Against Sewage. Plastic bags, they maintain, litter streets and the countryside and pollute the seas, where they cause considerable damage to marine life.

They propose a tax of 5p per bag, which would be passed on to consumers. Such a levy has already been introduced in Wales in October 2011. As a result, plastic bag use in Wales has dropped dramatically (see also the full report from the Welsh Government). The Scottish Government and the Northern Ireland Assembly are also planning introducing similar charges.

Many other governments have introduced taxes, charges or bans on plastic bags and many more are considering introducing such measures. Ireland introduced a 15 euro cent charge on single-use plastic bags as far back as 2002 and saw a 94% reduction in plastic bag use (328 per person per year to 21). The charge was raised to 22 euro cents in 2007 after bag use rose to 30 per person.

Other countries have banned plastic bags altogether: some, such as Rwanda and Somalia have banned all plastic bags; others, such as China and South Africa have banned very thin bags; others, such as Italy, have banned non-biodegradable ones.

In the USA, various states or districts have introduced levies and in the EU, where more than four billion bags are thrown away each year, the European Commission will soon publish proposals for limiting the use of plastic bags.

So what are the arguments for limiting the use of plastic bags? Why is it not enough to leave things simply to the market? And if the use of plastic bags is to be reduced, what’s the most efficient way of doing so? Are there any problems with alternatives to plastic bags? The following articles and reports consider these questions?

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.

The Office for Budget Responsibility has said that the UK Treasury will face a shortfall of £13bn in motoring taxes within a decade. Although car usage continues to rise putting increasing pressure on the road infrastructure, the greener and more fuel efficient cars being produced are driving down the tax revenues generated from motoring.

A report by the IFS has put forward the case for replacing the existing system of taxes on cars and fuel by a new road charging system. If no such change occurs, the IFS has forecast that with more electric cars and hence lower revenues raised from fuel and vehicle excise duties, the shortfall facing the Treasury would require an increase in fuel duty of some 50%. Instead of this, the solution could be to charge individuals for every mile of road they use, with the ‘price’ varying depending on the degree of congestion. For example, at peak times the price would be higher, where as for those in the countryside where roads are traditionally much quieter, charges would be lower. The IFS said:

‘Such a move would generate substantial economic efficiency gains from reduced congestion, reduce the tax levied on the majority of miles driven, leave many (particularly rural) motorists better off, and provide a stable long-term footing for motoring taxes without necessarily raising net additional revenue from drivers.’

Government policy across the world has been increasingly focused on climate change, with targets for emissions reductions being somewhat ambitious. However, many car manufactures who were told to reduce emissions significantly are on the way to meeting these targets and this success is a key factor contributing towards this new road ‘crisis’ that could soon be facing the government. The following articles consider the possibility of a road charging scheme.

Questions

  1. Illustrate the effect of a tax being imposed on petrol. What happens to the equilibrium price and quantity?
  2. Despite fuel duty pushing up the price of petrol, why has there been such a small decline in the quantity of petrol individuals use?
  3. Evaluate the case for and against a road charging scheme.
  4. Why are tax revenues from motoring expected to decline over the next decade?
  5. Climate change has become an increasingly important focus of government policy. To what extent is the current road ‘crisis’ a positive sign that policies to tackle climate change are working?
  6. If a road charging scheme went ahead and prices were varied depending on traffic, time etc, what name would you give to this strategy?
  7. Why would it be possible to charge a higher price at peak times and a lower price for cars using country roads?
  8. Is there an argument for privatising the road network? Is it even possible?

My son Andrew Sloman (see also) is currently in Goa. My wife Alison and I went to visit him over half term – our first trip to India. Goa is a beautiful state, with wonderful beaches, fantastic food and perfect weather in February. But inland from this tourist haven lies an environmental disaster caused by the open-cast extraction of iron ore.

This tiny state by Indian standards produces more than 60% of India’s iron ore exports. Whilst, along with tourism, the iron ore industry has been one of the largest contributors to the Goan economy, its environmental footprint is massive. Deforestation and water and air pollution are just three of the environmental externalities.

So should a cap be placed on the amount of iron ore that is mined? Should the industry be taxed more heavily? Should tough environmental standards be imposed on the industry? Or should it simply be allowed to continue, given its large contribution to the Goan economy? Or, at the other extreme, should the industry be closed? The linked article looks at some of the issues. Try to identify, as an economist, what information you would require in order to come to a conclusion to these questions.

Greens’ shout for cap on iron ore mining falls on deaf ears Times of India, Paul Fernandes (28/2/12)

Questions

  1. What negative externalities are involved with the Goan iron ore industry? Are there any positive externalities?
  2. What difficulties are there in measuring the negative externalities?
  3. How would you set about doing a cost–benefit analysis of (a) expanding the Goan iron ore industry; (b) shutting it?
  4. Explain the following: “The net present value of the opportunity cost for 25 years at 12% social discount rate of giving it up is greater than its environmental cost by Rs 14,449 crore, the report states.” (A crore is 10 million and Rs is the symbol for an Indian Rupee, where £1 = approximately 78 rupees.)
  5. What difficulties are there in attempting to take distribution into account when doing a cost–benefit analysis?

With the fall of communism in eastern Europe between 1989 and 1991, many hailed this as the victory of capitalism.

Even China, which is still governed by the Chinese Communist Party, has embraced the market and accepted growing levels of private ownership of capital. It is only one or two countries, such as North Korea and Cuba, that could be described as communist in the way the term was used to describe the centrally planned economies of eastern Europe before 1990.

But whilst market capitalism seemed to have emerged as the superior system in the 1990s, may are now questioning whether the market capitalism we have today is fit for the 21st century. Today much of the world’s capital in the hands of big business, with financial institutions holding a large proportion of shares in such companies. And the gap between rich and poor is ever widening

The market system of today, is very different from that of 100 years ago. In fact, as John Kay agues in his article “Let’s talk about the market economy” below, it would be wrong to describe it as ‘capitalism’ in the sense the term was used in the debates of the 19th and early 20th centuries. Nonetheless, the term is still used and generally refers to the market system we now have. And it is a market system that many see as failing and unfit for purpose. It is a system that coincided with the bubble of the 1990s and early 2000s, the credit crunch of 2007–9 and the recession of 2008/9, now seeming to return as a double-dip recession

With the political and business leaders of the world meeting at the World Economic Forum at Davos in Switzerland on 25–29 January 2012, a central theme of the forum has been the future of capitalism and whether it’s fit for the 21st century.

Is there a fairer and more compassionate capitalism that can be fostered? This has been a stated objective of all three political parties in the UK recently. Can we avoid another crisis of capitalism as seen in the late 2000s and which still continues today? What is the role of government in regulating the market system? Does the whole capitalist system need restructuring?

It’s becoming increasingly clear that we need to talk about capitalism. The following webcasts and articles do just that.
