Is slower economic growth a cost of cutting greenhouse gas emissions? Apparently not – at least according to two studies: one by DIW Econ, a German institute for economic research, and the other, earlier this year, by the International Energy Association (see reports below).
The IEA study found that, despite global GDP having grown by 6.4% in 2014, global emissions remained flat. The DIW Econ study found that from 2004 to 2014, OECD countries as a whole grew by 16% while cutting fossil fuel consumption by 6% and greenhouse gas emissions by 6.4%.
But what does this mean? If growth accelerated, what would happen to greenhouse gas emissions? Would they begin to rise again? Probably.
The point is that various developments, largely independent of economic growth have been reducing the greenhouse gas emissions/GDP ratio. These developments include: technological advances in energy generation; the switch to alternative fuels in many countries, thanks, in large part to lower renewable energy costs; increased energy efficiency by consumers; and a continuing move from energy-intensive manufacturing to less energy-intensive services.
So if governments forced more radical cuts in greenhouse gases, would this reduce the rate of economic growth or have no effect? For a given level of technological advancement, the initial effect would probably be a reduction in economic growth. But to the extent that this encouraged further investment in renewables and energy saving, it might even stimulate economic growth over the longer term, especially if it helped to bring lower energy prices.
A big problem in decoupling economic growth from fossil fuel usage is that developing countries, which are taking a growing share of world manufacturing, are more heavily dependent on coal than most developed countries. But even here there seems to be some hope. China, the biggest manufacturer in the developing world, is rapidly increasing its use of renewables. As the IEA press release states:
In China, 2014 saw greater generation of electricity from renewable sources, such as hydropower, solar and wind, and less burning of coal.
If the world is to tackle global warming by making significant cuts in greenhouse gases, there must be a way for developing countries to continue growing while making less use of fossil fuels.

The second largest economy in the world, with a record expansion to its current economic status: China. With a phenomenal population, massive migration to the cities and incredible infrastructure development, China has fast become a key economic player, with environmental and pollution problems to match.
The price of China’s economic development may be too high for some people. Increases in incomes, growth and employment may be good news, but is the cost too high? Do economic growth and progress mean poor health and if so, is this a price worth paying
Another big topic within China is the impact on inequality. With growth accelerating in urban areas, population movement from the rural to the urban has been a common feature across China, but this has also created greater inequality. This population movement has separated families and played a role in creating barriers of access to health and education.
The following article from the BBC considers a range of indicators within China and you may also want to review some earlier blog postings on the Sloman News Site which analyse the Chinese economy.

Questions
- What are the key drivers of China’s development?
- What are the costs and benefits of rural-urban migration?
- To what extent do you think there may be a trade-off between quality and quantity when it comes to infrastructure projects? Or is Chinese labour simply more efficient relative to countries such as the UK?
- How should we measure economic development? If access to education and health care is limited in the more rural areas, but widely available in the larger cities, does this suggest a country that is developing?
- What are the main externalities that China must tackle? Are they domestic issues or global ones? What about the solutions?
- If a key driver of Chinese growth and development is government investment in infrastructure projects, is this true and sustainable growth or do you think it might slowly disappear if the government doesn’t continue to invest?
- Do you think the relative success of China can be replicated in other emerging nations and in particular in nations within Africa?
Productivity has been a bit of a problem for the UK economy for a number of years. Earlier posts from 2015 have discussed the trend in Tackling the UK’s poor productivity and The UK’s poor productivity record. Although the so-called ‘productivity gap’ has been targeted by the government, with George Osborne promising to take steps to encourage more long-term investment in infrastructure and create better incentives for businesses to improve productivity, the latest data suggest that the problem remains.
The ONS has found that the UK continues to lag behind the other members of the G7, but perhaps more concerning is that the gap has grown to its biggest since 1991. The data showed that output per hour worked was 20 percentage points lower in the UK than the average for the other G7 countries. The economic downturn did cause falls in productivity, but the UK has not recovered as much as other advanced nations. One of the reasons, according to the Howard Archer, chief UK economist at IHS Global Insight is that it ‘had been held back since the financial crisis by the creation of lots of low-skilled, low-paid jobs’. These are the jobs where productivity is lowest and this may be causing the productivity gap to expand. Other cited reasons include the lack of investment which Osborne is attempting to address, fewer innovations and problems of finance.
Despite these rather dis-heartening data, there are some signs that things have begun to turn around. In the first quarter of 2015, output per hour worked did increase at the fastest annual growth rate in 3 years and Howard Archer confirmed that this did show ‘clear sign that UK productivity is now seeing much-needed improvement.’ There are other signs that we should be optimistic, delivered by the Bank of England. Sir John Cunliffe, Deputy Governor for financial stability said:
“firms have a greater incentive to find efficiency gains and to switch away from more labour-intensive forms of production. This should boost productivity.”
The reason given for this optimism is the increase in the real cost of labour relative to the cost of investment. So, a bit of a mixed picture here. UK productivity remains a cause for concern and given its importance in improving living standards, the Conservative government will be keen to demonstrate that its policies are closing the productivity gap. The latest data is more promising, but that still leaves a long way to go. The following articles consider this data and news.

Interest rates are the main tool of monetary policy and have a history of being an effective tool in creating macroeconomic stability. There has been much discussion since the end of the financial crisis concerning when interest rates would rise in the US (and the UK) and for the US, the case is stronger, given its rate of growth, which has averaged at 2.2% per annum since June 2009.
As in the UK, the question of ‘will rates rise?’ has a clear and certain answer: Yes. The more challenging question is ‘when?’. Much of the macroeconomic data for the US is promising, with positive economic growth (and relatively strong in comparison to the UK and Eurozone), a low unemployment rate and inflation of 0.3%. This last figure is ‘too low’, but it comes in at a much more attractive 1.2% if you exclude food and energy costs and there is an argument for doing this, given the price of oil. The data on unemployment and growth might suggest that the economy is at a stage where a rate rise could be managed, but the inflation data indicates that low interest rates might be needed to keep inflation above 0%. Furthermore, there are concerns that the low unemployment figure is somewhat misleading, given that under-employment is quite high at 10.3% and there are still many who are long-term unemployed, having been out of work for more than 6 months.
Interest rates can be a powerful tool in affecting the components of aggregate demand (AD) and hence the macroeconomic variables. If interest rates fall, it can help to stimulate AD by reducing borrowing costs for consumers and businesses, reducing the incentive to save, cutting variable rate mortgage payments and depreciating the exchange rate. Collectively these effects can stimulate an economy and hence create economic growth, reduce unemployment and push up prices. However, interest rates have been at almost 0% since the financial crisis, so the only way is up. Reversing the aforementioned effects could then spell trouble, if the economy is not in a sufficiently strong position.
For many, the strength of the US economy, while relatively good, is not yet good enough to justify a rate rise. It may harm investment, growth and unemployment and none of these variables are sufficiently high to warrant a rate rise, especially given the slowdown in the emerging markets. Karishma Vaswani, from BBC News said:
“The current global hand-wringing and head-holding over whether the US Fed will or won’t raise interest rates later has got investors here in Asia worried about what this means for their economies.
The Fed has become the favourite whipping boy of Asia’s central bankers, with cries from India to Indonesia to “just get on with it”.”
There are many, including Professor John Taylor from Stanford University and a former senior Treasury official, a rate rise is well over-due. The market is expecting one and has been for some time and these expectations aren’t going away, so ‘just get on with it.’ Janet Yellen, the Chair of the Federal Reserve is in a tricky situation. She knows that whatever is decided, markets around the world will react – no pressure then! The following articles consider the interest rate debate.

China has a key role in the global economy. Recording double digit growth for a number of years and posting impressive export figures, China’s has been an economy on an upward trajectory. But its growth has been slowing and this might spell trouble for the global economy, as was discussed in the following blog. For many, China is the pendulum and the direction it moves in will have a big influence on many other countries.
There are some suggestions that China’s rapid growth has been somewhat artificial, in particular following the financial crisis, where we saw massive investment by state-owner enterprises, banks and local government. This has led to a severe imbalance within the Chinese economy, with high levels of debt. One of the key factors that has enabled China to grow so quickly has been strong exports. China has typically had a large current account surplus, often balanced by large current account deficits in many Western countries.
The exchange rate is a key component in keeping strong export growth and the devaluation of the Chinese currency in August (see What a devalued yuan means to the rest of the world) is perhaps a suggestion that export growth in China is lower than desired. Devaluing the currency will boost the competitiveness of Chinese exports and this in turn may lead to a growth in the current account surplus, which had fallen quite significantly from around 10% to 2%.
The problem is that China is currently imbalanced and this is likely to create problems around the world. With globalisation, the free movement of capital and people, deflation in the West and falling world asset prices, the situation in China is crucial. Although you will find many articles about China and blogs on this site about its devaluation, its growth and policy, the BBC News article below considers the conflicts that exist between three key economic objectives:
1. currency stability
2. the free movement of capital
3. independent monetary policy
and the need for some international co-operation and co-ordination to enable China’s economy to return to internal and external balance.
China’s impossible trinity BBC News, Duncan Weldon (8/9/15)
Questions
- What is meant by internal balance?
- What is external balance?
- Would you suggest that China is suffering from an imbalanced economy? If so, which type of imbalance and why is this a problem for China and for the world economy?
- The article refers to the trilemma. Why can an country not achieve all 3 parts of the trilemma? You should explain why each combination of 2 aspects is possible, but why the third is problematic.
- Use a diagram to explain why a fall in the exchange rate will boost the competitiveness of exports and why this can create economic growth.
- Why is a devalued Chinese currency bad news for the rest of the world?
- How could international co-operation and co-ordination help China?
Is slower economic growth a cost of cutting greenhouse gas emissions? Apparently not – at least according to two studies: one by DIW Econ, a German institute for economic research, and the other, earlier this year, by the International Energy Association (see reports below).
So if governments forced more radical cuts in greenhouse gases, would this reduce the rate of economic growth or have no effect? For a given level of technological advancement, the initial effect would probably be a reduction in economic growth. But to the extent that this encouraged further investment in renewables and energy saving, it might even stimulate economic growth over the longer term, especially if it helped to bring lower energy prices.
