Australia held a general election on 2 July 2016. The Liberal/National coalition narrowly won in the House of Representatives, gaining a substantially reduced majority of 77 of the 150 seats, to Labor’s 68 and other parties’ 5 seats. One campaign issue for all parties was the destruction of the Great Barrier Reef, which is seen as an environmental disaster. Each party had proposals for tackling the problem and we examine some of them here.

The Great Barrier Reef is the largest coral reef in the world. As the BBC’s iWonder guide states:

One of the world’s seven natural wonders, the Great Barrier Reef contains some 900 islands and 3000 smaller reefs. It is larger than the UK, the Netherlands and Switzerland combined, home to around 10% of the world’s marine fish, over 200 bird species and countless other animals, including turtles and dolphins.

But this iconic Reef system is facing unprecedented threats. Together with governments, scientists are playing a key role in the battle to preserve this vulnerable ecosystem before it’s too late.

The Reef is 2300km long. In the northern third, around half of the coral is dead. Few tourists see this, as they tend to dive in the southern third, which, being cooler, is less affected.

The bleaching and destruction of coral reefs has a number of causes. These include: rising water temperatures, generally from global warming and more extreme El Niño events (rising warm waters that periodically spread across the Pacific); pollution, including that from coal mining, industrial effluent and run-off of pesticides, herbicides, fertilisers and sediment from farming, leading to acidification of waters; more frequent and more violent cyclones; rapidly expanding numbers of coral-eating Crown of Thorns starfish; and over fishing of some species of fish, leading to knock-on effects on ecosystems.

The Barrier Reef and the oceans and atmosphere around it can be regarded as a common resource. The warming of the atmosphere and the oceans, and the destruction of the reef and the wildlife on it, are examples of the ‘tragedy of the commons’. With no-one owning these resources, they are likely to be overused and abused. Put another way, these activities cause negative externalities, which do not appear as costs to the polluters and despoilers, but are still costs to all who treasure the reef. And, from a non-human perspective, it is a cost to the planet and its biodiversity. What is in the private interests of the abusers is not in the social or environmental interest.

The Australian government had sought to downplay the extent of the problem, afraid of deterring tourists – a valuable source of revenue – and under pressure from the coal and farming industries. Nevertheless, in the run-up to the election, the destruction of the Reef and what to do about it became a major debating point between the parties.

The Coalition government has pledged A$1bn for a new Reef fund, which will be dedicated to tackling climate change and water quality.

The fund will also help coastal sewage treatment plants to reduce ocean outfalls with efficient pumps, biogas electricity generation and next-generation waste water treatment. Improving water quality will enhance the Reef’s resilience to climate change, coral bleaching and outbreaks of the destructive crown of thorns starfish.

But how much difference the fund can make with the money it will have is not clear.

The Labor Party pledged to follow every recommendation in the Great Barrier Reef Water Science Taskforce’s Final Report, released in May, and to pass laws to prevent farm pollution flowing into the waters around the Reef and to have a more rapid shift towards renewable energy.

The Green Party goes the furthest. In addition to the Labor Party’s proposals, it wants to impose taxes on coal firms equal to the cost of the damage they are causing. The tax revenues would be paid into a multi-billion dollar fund. This would then be spent on measures to rescue the Reef, invest in clean energy projects, stop damaging industrial development, improve farm management and stop polluted run-off into the Reef catchment area by investing in water systems.

Promises at the time of an election are all well and good. Just how much will be done by the re-elected Coalition government remains to be seen.

What have been, and will be, the monetary and fiscal responses to the Brexit vote in the referendum of 23 June 2016? This question has been addressed in speeches by Mark Carney, Governor of the Bank of England, and by George Osborne, Chancellor the Exchequer. Both recognise that the vote will cause a negative shock to the economy, which will require some stimulus to aggregate demand to avoid a recession, or at least minimise its depth.

Mark Carney stated that:

The Bank of England stands ready to provide more than £250bn of additional funds through its normal facilities. The Bank of England is also able to provide substantial liquidity in foreign currency, if required.

In the coming weeks, the Bank will assess economic conditions and will consider any additional policy responses.

This could mean that at its the next meeting, scheduled for 13/14 July, the Monetary Policy Committee will consider reducing Bank Rate from its current level of 0.5% and introducing further quantitative easing.

In a speech on 30 June, he went further:

I can assure you that in the coming months the Bank can be expected to take whatever action is needed to support growth subject to inflation being projected to return to the target over an appropriate horizon, and inflation expectations remaining well anchored.

Then in a speech on 5 July, introducing the latest Financial Stability Report, he said that the Bank of England’s Financial Policy Committee is lowering the required capital ratio of banks, thereby freeing up capital for lending to customers. The part being lowered is the ‘countercyclical capital buffer’ – the element that can be varied according to the state of the economy. Mark Carney said:

The FPC is today reducing the countercyclical capital buffer on banks’ UK exposures from 0.5% to 0% with immediate effect. This is a major change. It means that three quarters of UK banks, accounting for 90% of the stock of UK lending, will immediately have greater flexibility to supply credit to UK households and firms.

Specifically, the FPC’s action immediately reduces regulatory capital buffers by £5.7 billion and therefore raises banks’ capacity to lend to UK businesses and households by up to £150 billion. For comparison, last year with a fully functioning banking system and one of the fastest growing economies in the G7, total net lending in the UK was £60 billion.

Thus although there may be changes to interest rates and narrow money in response to economic reactions to the Brexit vote, the monetary policy framework remains unchanged. This is to achieve a target rate of CPI inflation of 2% at the 24-month time horizon.

But what of fiscal policy?

In its Charter for Budget Responsibility, updated in the Summer 2015 Budget, the government states its Fiscal Mandate:

3.2 In normal times, once a headline surplus has been achieved, the Treasury’s mandate for fiscal policy is:
   a target for a surplus on public-sector net borrowing in each subsequent year.

3.3 For the period outside normal times from 2015-16, the Treasury’s mandate for fiscal policy is:
   a target for a surplus on public-sector net borrowing by the end of 2019-20.

3.4 For this period until 2019-20, the Treasury’s mandate for fiscal policy is supplemented by:
   a target for public-sector net debt as a percentage of GDP to be falling in each year.

The target of a PSNB surplus by 2019-20 has been the cornerstone of recent fiscal policy. In order to stick to it, the Chancellor warned before the referendum that a slowdown in the economy as a result of a Brexit vote would force him to introduce an emergency Budget, which would involve cuts in government expenditure and increases in taxes.

However, since the vote he is now saying that the slowdown would force him to extend the time for reaching a surplus beyond 2019-20 to avoid dampening the economy further. But does this mean he is abandoning his fiscal target and resorting to discretionary expansionary fiscal policy?

George Osborne’s answer to this question is no. He argues that extending the deadline for a surplus is consistent with paragraph 3.5 of the Charter, which reads:

3.5 These targets apply unless and until the Office for Budget Responsibility (OBR) assess, as part of their economic and fiscal forecast, that there is a significant negative shock to the UK. A significant negative shock is defined as real GDP growth of less than 1% on a rolling 4 quarter-on-4 quarter basis. If the OBR assess that a significant negative shock:

occurred in the most recent 4 quarter period;
is occurring at the time the assessment is being made; or
will occur during the forecast period

then:

  if the normal times surplus rule in 3.2 is in force, the target for a surplus each year is suspended (regardless of future data revisions). The Treasury must set out a plan to return to surplus. This plan must include appropriate fiscal targets, which will be assessed by the OBR. The plan, including fiscal targets, must be presented by the Chancellor of the Exchequer to Parliament at or before the first financial report after the shock. The new fiscal targets must be approved by a vote in the House of Commons.
  if the shock occurs outside normal times, the Treasury will review the appropriateness of its fiscal targets for the period until the public finances return to surplus. Any changes to the targets must be approved by a vote in the House of Commons.
  once the budget is in surplus, the target set out in 3.2 above applies.

In other words, if the OBR forecasts that the Brexit vote will result in GDP growing by less than 1%, the Chancellor can delay reaching the surplus and thus not have to introduce tougher austerity measures. This, in effect, is what he is now saying and maintaining that, because of paragraph 3.5, it does not break the Fiscal Mandate. The nature of the next Budget, probably in the autumn, will depend on OBR forecasts.

A few days later, George Osborne announced that he plans to cut corporation tax from the current 20% to less than 15% – below the rate of 17% previously scheduled for 2019-20. His aim is not just to stimulate the economy, but to attract inward investment, as the rate would below that of any major economy and close the rate of 12.5% in Ireland. His hope would also be to halt the outflow of investment as companies seek to relocate in the EU.

In June 2014, the Gas and Electricity Markets Authority (which governs the energy regulator, Ofgem) referred Great Britain’s retail and wholesale gas and electricity markets to the Competition and Markets Authority (CMA). The market is dominated by the ‘big six‘ energy companies (British Gas, EDF, E.ON, npower, Scottish Power and SSE) and Ofgem suspected that this oligopoly was distorting competition and leading to higher prices.

The CMA presented its report on 10 March 2016. It confirmed its preliminary findings of July and December 2015 “that there are features of the markets for the supply of energy in Great Britain that result in an adverse effect on competition”. It concludes that “the average customer could save over £300 by switching to a cheaper deal” and that “customers could have been paying about £1.7 billion a year more than they would in a competitive market”.

It made various recommendations to address the problem. These include “requiring the largest suppliers to provide fuller information on their financial performance” and strengthening the role of Ofgem.

Also the CMA wants to encourage more people to switch to cheaper suppliers. At present, some 70% of the customers of the big six are on default standard variable tariffs, which are more expensive than other tariffs available. To address this problem, the CMA proposes the setting up of “an Ofgem-controlled database which will allow rival suppliers to contact domestic and microbusiness customers who have been stuck on their supplier’s default tariff for 3 years or more with better deals.”

Another area of concern for the CMA is the 4 million people (16% of customers) forced to have pre-payment meters. These tend to be customers with poor credit records, who also tend to be on low incomes. Such customers are paying more for their gas and electricity and yet have little opportunity to switch to cheaper alternatives. For these customers the CMA proposed imposing transitional price controls from no later than April 2017 until 2020. These would cut typical bills by some £80 to £90 per year. In the meantime, the CMA would seek to remove “restrictions on the ability of new suppliers to compete for prepayment customers and reduce barriers such as debt issues that make it difficult for such customers to switch”.

Despite trying to address the problem of lack of competition, consumer inertia and barriers to entry, the CMA has been criticised for not going further. It has also been criticised for the method it has chosen to help consumers switch to cheaper alternative suppliers and tariffs. The articles below look at these criticisms.

Questions

  1. Find out the market share of the ‘big six’ and whether this has changed over the past few years.
  2. What, if any, are the barriers to entry in the gas and electricity retail markets?
  3. Why are the big six able to charge customers some £300 per household more than would be the case if they were on the cheapest deal?
  4. What criticisms have been made of the CMA’s proposals?
  5. Discuss alternative proposals to those of the CMA for dealing with the problem of excessive prices of gas and electricity.
  6. Should Ofgem or another independent not-for-profit body be allowed to run its own price comparison and switching service? Would this be better than the CMA’s proposal for allowing competitors access to people’s energy usage after 3 years of being with the same company on its standard tariff and allowing them to contact these people?

People are beginning to get used to low oil prices and acting as if they are going to remain low. Oil is trading at only a little over $30 per barrel and Saudi Arabia is unwilling to backtrack on its policy of maintaining its level of production and not seeking to prevent oil prices from falling. Currently, there is still a position of over supply and hence in the short term the price could continue falling – perhaps to $20 per barrel.

But what of the future? What will happen in the medium term (6 to 12 months) and the longer term? Investment in new oil wells, both conventional and shale oil, have declined substantially. The position of over supply could rapidly come to an end. The Telegraph article below quotes the International Energy Agency’s executive director, Fatih Birol, as saying:

“Investment in oil exploration and production across the world has been cut to the bone, falling 24% last year and an estimated 17% this year. This is… far below the minimum levels needed to keep up with future demand. …

It is easy for consumers to be lulled into complacency by ample stocks and low prices today, but they should heed the writing on the wall: the historic investment cuts raise the odds of unpleasant oil security surprises in the not too distant future.”

And in the Overview of the IEA’s 2016 Medium-Term Oil Market Report, it is stated that

In today’s oil market there is hardly any spare production capacity other than in Saudi Arabia and Iran and significant investment is required just to maintain existing production before we move on to provide the new capacity needed to meet rising oil demand. The risk of a sharp oil price rise towards the later part of our forecast arising from insufficient investment is as potentially de-stabilising as the sharp oil price fall has proved to be.

The higher-cost conventional producers, such as Venezuela, Nigeria, Angola, Russia and off-shore producers, could take a long time to rebuild capacity as investment in conventional wells is costly, especially off-shore.

As far as shale oil producers is concerned – the prime target of Saudi Arabia’s policy of not cutting back supply – production could well bounce back after a relatively short time as wells are re-opened and investment in new wells is resumed.

But, price rises in the medium term could then be followed by lower prices again a year or two thereafter as oil from new investment comes on stream: or they could continue rising if investment is insufficient. It depends on the overall balance of demand and supply. The table shows the IEA’s forecast of production and consumption and the effect on oil stocks. From 2018, it is predicting that consumption will exceed production and that, therefore, stocks will fall – and at an accelerating rate.

But just what happens to the balance of production and consumption will also depend on expectations. If shale oil investors believe that an oil price bounce is temporary, they are likely to hold off investing. But this will, in turn, help to sustain a price bounce, which in turn, could help to encourage investment. So expectations of investors will depend on what other investors expect to happen – a very difficult outcome to predict. It’s a form of Keynesian beauty contest (see the blog post A stock market beauty contest of the machines) where what is important is what other people think will happen, which in turn depends on what they think other people will do, and so on.

Pork – a favourite food of many Brits, whether it’s as a key ingredient of a roast dinner or a full English Breakfast! But, British pig farmers may be in for a tricky ride and we might be seeing foreign pork on our plates in the months to come. This is because of the falling price of pork, which may be driving local farmers out of the market.

As we know, market prices are determined by the interaction of demand and supply and as market conditions change, this will affect the price at which pork sells at. This in turn will have an impact on the incomes of farmers and hence on farmers’ ability to survive in the market. According to forecasts from Defra, specialist pig farms are expected to see a fall in income by 46%, from £49,400 to £26,500 in 2016. A key driver of this, is the decline in the price of pork, which have fallen by an average of £10 per pig. This loss in income has led to pig farmers facing the largest declines of any type of farm, even beating the declines of dairy farmers, which have been well-documented.

If we think about the forces of demand and supply and how these have led to such declines in prices, we can turn to a few key things. Following the troubles in Russia and the Ukraine and Western sanctions being imposed on Russia, a retaliation of sorts was Russia banning European food imports. This therefore reduced demand for British pork. Adding to this decline in demand, there were further factors pushing down demand, following suggestions about the adverse impact that bacon and ham have on health. If pig farmers in the UK continue with the number of pigs they have and bearing in mind they would have invested in their pig farms before such bans and warnings were issued, then we see supply being maintained, demand falling and prices being pushed downwards.

Zoe Davies, Chief Executive of the National Pig Association said:

“This year is going to be horrendous for the British pig industry … Trading has been tough for at least 18 months now and we are starting to see people leave. We’re already seeing people calling in saying they’ve decided to give up. All we can hope is that more people leave European pig farms before ours do.”

We can also look to other factors that have been driving pig farmers out of business, including a strong pound, the glut of supply in Europe and productivity in the UK. Lily Hiscock, a commentator in this market said:

“It is estimated that the average pig producer is now in a loss-making position after 18 months of positive margins … The key factors behind the fall in markets are the exchange rate, UK productivity and retail demand … Indeed, pigmeat seems to be losing out to cheaper poultry meat in consumers’ shopping baskets … The recent fall in prices may stimulate additional demand, and a strengthening economy could help, but at present these are hopes rather than expectations.”

The future of British pig farms is hanging in the balance. If the economy grows, then demand may rise, offsetting the fall in demand being driven by other factors. We will also see how the exit of pig farmers affects prices, as each pig farmer drops out of the market, supply is being cut and prices rise. Though this is not good news for the farmers who go out of business, it may be an example of survival of the fittest. The following articles consider the market for pork.
