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.

You’ll be familiar with these types of posts from me, which typically start with a comment like: ‘On my commute to work on …’. That’s one of the good things about a long drive – the interesting and informative discussions that you hear on the radio. This one is another interesting piece from BBC Radio 4, looking at a very topical issue, especially to those living in the South West and other rural areas in the UK.

We have recently seen pictures of farmers protesting about the price of milk and in places like Somerset, the protest took a rather odd method, where farmers from across the region entered supermarkets and simply bought all of the milk, before giving it away. The issue is that dairy farming is no longer profitable, as the price that dairy farmers receive for each pint of milk is now lower than the cost of providing it. Thus, for each pint they make a loss.

There are many reasons that have contributed to this situation, including pressures imposed by customers demanding cheaper prices; pressures from supermarkets using their monopsony power to force down the prices paid to farmers; and pressures from abroad. In the case of milk, we have a surplus and with a perishable product, i.e. one that cannot be stored, unlike wheat, this has contributed to falling prices. Data suggest that we are seeing approximately one farmer per day being forced to leave the indsutry.

This programme explores the current dairy farming crisis and draws some similarities with the wheat crisis that the UK experienced in the 1930s. The programme below is 30 minutes and provides some interesting insights on two important commodities and the economics behind the markets.

Today’s crisis in dairy farming and the wheat crisis of the 1930s BBC Radio 4; The Long View, Jonathan Freedland (29/9/15)

Questions

  1. Using demand and supply analysis, explain the situation in the milk market.
  2. Now consider the wheat industry and provide a similar analysis of how prices are set and what caused the problems seen in the 1930s.
  3. Although these two commodities have similarities they are also very different. Why can two different commodities experience such similar problems at such different times?
  4. What are the key demand and supply-side factors affecting the current low price of milk?
  5. Consider the market for (a) milk and (b) wheat. What are (if any) the market failures within each area?
  6. Agriculture is an area where we do see significant government intervention. Should the UK government be doing more to help the UK’s dairy farmers? If so, what should they do and would this intervention create further problems, e.g. unintended consequences?

What will production look like in 20 years time? Will familiar jobs in both manufacturing and the services be taken over by robots? And if so, which ones? What will be the effect on wages and on unemployment? Will most people be better off, or will just a few gain while others get by with minimum-wage jobs or no jobs at all?

The BBC has been running a series looking at new uses for robots and whether they will take people’s jobs? This complements three reports: one by Boston Consulting one by Deloitte and an earlier one by Deloitte and Michael Osborne and Carl Frey from Oxford University’s Martin School. As Jane Wakefield, the BBC’s technology reporter states:

Boston Consulting Group predicts that by 2025, up to a quarter of jobs will be replaced by either smart software or robots, while a study from Oxford University has suggested that 35% of existing UK jobs are at risk of automation in the next 20 years.

Jobs at threat from machines include factory work, office work, work in the leisure sector, work in medicine, law, education and other professions, train drivers and even taxi and lorry drivers. At present, in many of these jobs machines work alongside humans. For example, robots on production lines are common, and robots help doctors perform surgery and provide other back-up services in medicine.

A robot may not yet have a good bedside manner but it is pretty good at wading through huge reams of data to find possible treatments for diseases.

Even if robots don’t take over all jobs in these fields, they are likely to replace an increasing proportion of many of these jobs, leaving humans to concentrate on the areas that require judgement, creativity, human empathy and finesse.

These developments raise a number of questions. If robots have a higher marginal revenue product/marginal cost ratio than humans, will employers choose to replace humans by robots, wholly or in part? How are investment costs factored into the decision? And what about industrial relations? Will employers risk disputes with employees? Will they simply be concerned with maximising profit or will they take wider social concerns into account?

Then there is the question of what new jobs would be created for those who lose their jobs to machines. According to the earlier Deloitte study, which focused on London, over 80% of companies in London say that over the next 10 years they will be most likely to take on people with skills in ‘digital know-how’, ‘management’ and ‘creativity’.

But even if new jobs are created through the extra spending power generated by the extra production – and this has been the pattern since the start of the industrial revolution some 250 years ago – will these new jobs be open largely to those with high levels of transferable skills? Will the result be an ever widening of the income gap between rich and poor? Or will there be plenty of new jobs throughout the economy in a wide variety of areas where humans are valued for the special qualities they bring? As the authors of the later Deloitte paper state:

The dominant trend is of contracting employment in agriculture and manufacturing being more than offset by rapid growth in the caring, creative, technology and business services sectors.

The issues of job replacement and job creation, and of the effects on income distribution and the balance between work and leisure, are considered in the following videos and articles, and in the three reports.

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

  1. What are the key drivers of China’s development?
  2. What are the costs and benefits of rural-urban migration?
  3. 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?
  4. 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?
  5. What are the main externalities that China must tackle? Are they domestic issues or global ones? What about the solutions?
  6. 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?
  7. 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.
