HS2: Do the costs exceed the benefits?

HS2 has been a controversial topic for some time now. Between the disruption it would cause to countless neighbourhoods and the protests that have emerged and the debate about the cost effectiveness of the project, it’s been in the news a fair amount. The transport network in the UK needs improving, not only for businesses located here, but also to encourage more investment into the country. HS2 is one of the solutions offered.

The latest estimate for the cost of HS2 is over £40 billion. However, many suggest that the benefits HS2 will bring do not cover the full costs. Furthermore, as noted above, other concerns include the disruption that it will bring to countless households who will be living along the proposed routes. Cost benefit analysis have been carried out to determine the viability of the project, but they are invariably difficult to do. As they involve determining all of the private and social costs and benefits and putting a monetary estimate onto them, there will inevitably be factors that are over-looked, under-estimated or over-estimated. The suggestions here are that the costs have been under-estimated and the benefits over-estimated.

In September, KPMG produced a report that estimated the overall benefit to the UK economy would be a boost to growth of 0.8%, which would benefit many businesses and communities. The British Chambers of Commerce said:

Business communities in dozens of cities and towns, from many parts of the UK, remain strongly supportive of HS2.

The railway network is also approaching full capacity and this is one of the reasons why HS2 has been proposed. A government source said:

We need to do something because our railways are nearly full, but the alternative to HS2 is a patch and mend job that would cause 14 years of gridlock, hellish journeys and rail replacement buses … The three main routes to the north would be crippled and the economy would be damaged.

However, this report has faced criticism, in particular because it ignored a variety of supply-side constraints and because they argue it would be more effective to simply update the existing network. However, a new government-commissioned report has suggested that this alternative to HS2 would involve 14 years of weekend route closures and much longer journey times. However, those in favour of updating existing routes have said that this new report commissioned by the government is ‘a complete fabrication’. Hilary Wharf of the HS2 Action Alliance commented:

This government-funded report is a complete fabrication. The main alternative to HS2 involves longer trains and reduced first-class capacity to provide more standard class seats…No work is required at Euston to deliver the necessary capacity increase. Work is only required at three locations on the WCML [West Coast Main Line], and this is comparable to the work being carried out on the route at present.

The debate regarding HS2 will continue for the time being and it is just another area that is fuelling the political playing field. Whatever is done, the rail network certainly requires investment, whether it is through HS2 or upgrades to the existing routes. The following reports and articles consider the latest developments and controversy regarding HS2.

A respectful debate about austerity versus stimulus

There has been an interesting debate recently about whether the austerity policies being pursued in the UK are the correct ones. What would have happened if the government had pursued a more expansionary policy? Would the increase in borrowing, at least in the short term, have triggered a financial crisis?

Without austerity policies, would the eurozone crisis have led to a collapse in investor confidence in the UK, especially if Greece had been forced out of the euro?

On the one side, Kenneth Rogoff argues that increasing the UK’s budget deficit would have been dangerous and could have led to a flight from the pound. Generally, but with some reservations, he supports the fiscal policies that have been pursued by the Coalition.

I am certainly not arguing that the UK or other advanced countries handled the post-crisis period perfectly. There should have been more infrastructure spending, even more aggressive monetary policy and probably more ruthless bank restructuring. But there has to be a balance between stimulus and stability. To assume we always knew things would calm down, and to retrospectively calibrate policy advice accordingly, is absurd

Paul Krugman and Simon Wren-Lewis challenge Rogoff’s arguments. Paul Krugman uses a version of the IS-LM model to analyse the effect of a loss of international confidence in the UK following problems in the eurozone and worries about excessive UK borrowing.

In the model, the LM curve (labelled MP in Krugman’s diagrams) illustrates the effect of an increase in real GDP on interest rates with a particular monetary policy (e.g. an inflation target or a Taylor rule, which involves a mix of two policy objectives: an inflation target and real GDP). As GDP rises, putting upward pressure on inflation, so the central bank will raise interest rates. Hence, like the traditional LM curve, the monetary-policy related LM curve will slope upwards, as shown in the diagram.

Initial equilibrium GDP is Y0. The rate of interest is at the minimum level, r0 (i.e. the rate of 0.5% that the Monetary Policy Committee has set since January 2009). This, in the model, is the liquidity trap, where any increase in money supply (a rightward shift in the LM curve) will have no effect on interest rates or GDP.

In Rogoff’s analysis of a crisis triggered by excessive borrowing and problems in the eurozone, the IS curve will shift to the left (as illustrated by curve IS1) as capital flows from the UK and confidence collapses. Real GDP will fall to Y1. This will be the outcome of fiscal expansion in the world of the early 2010s.

Krugman argues that the opposite will occur. The outflow of capital will drive down the exchange rate. This will lead to an increase in exports and a decrease in imports. Aggregate demand thus rises and the IS curve will shift to the right (e.g. to IS2 in the diagram. Real GDP will rise (e.g. to Y2 in the diagram). If the rise in aggregate demand is sufficient, the economy will rise out of the liquidity trap and interest rates will rise (e.g. to r2 in the diagram).

Not surprisingly, Rogoff challenges this analysis, as you will see if you read his second paper below. He doesn’t criticise the model per se, but challenges Krugman’s assumptions. For example, a depreciation of sterling by some 20% since 2008 doesn’t seem to have had a major effect in stimulating exports (see the chart in the news item, A balancing act). And exports could well have declined if the eurozone economy had collapsed, given that exports to the eurozone account for around 44% of total UK exports.

Rogoff’s assumptions in turn can be challenged. Simon Wren-Lewis argues that, provided a credible long-term plan for deficit reduction is in place, maintaining a fiscal stimulus in the short run, to keep the recovery going that was beginning to emerge in 2010, would help to increase investor confidence, not undermine it. And, with a policy of quantitative easing, which involves the Bank of England buying central government debt, there is no problem of a lack of demand for UK gilts by the private sector.

What is clear from this debate is the willingness of both sides to accept points made by the other. It is an extremely civilised debate. In fact, it could be seen as a model of how academic debate should be conducted. There is none of the ‘shouting’ that has charaterised much of the pro- and anti-austerity lobbying since the financial crisis burst onto the world stage.

A (further) review of recent UK growth numbers

The latest preliminary GDP estimates for 2013 Q3 suggest that the economy’s output (real GDP) expanded by 0.8 per cent following on the back of a 0.7 per cent increase in Q2. Growth was observed across the main industrial sectors with the important service sector growing by 0.7 per cent. While the output of the service sector is now 0.5 per cent higher than its 2008 Q1 peak, the total output of the economy remains 2.6 per cent below its 2008 Q1 peak.

The volatility of growth underpins the idea of business cycles and on occasions results in recessions. Today’s release needs to be set in the context of this volatility and in the context of 2008/9 recession which saw output fall by 7.2 per cent. UK output peaked in 2008 Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters during which output declined.

Output declined again in 2010 Q4 (–0.2% growth) and again in 2011 Q4 (–0.1% growth). The estimates of real GDP for 2011 Q4 and 2012 Q1 are identical at £376.462 billion (at 2010 prices). Previous revisions have seen the 2012 Q1 growth number revised up so that a further recession resulting in a double-dip recession no longer appears in the figures.

While output is now portrayed as (very) flat in 2012 Q1, it did fall again in 2012 Q2 (–0.5 per cent growth) and in 2012 Q4 (–0.3 per cent growth). Moving forward in time, the latest ONS numbers show an economy that grew by 0.4 per cent in 2013 Q1 (to £377.301 billion at 2010 prices), by 0.7 per cent in 2013 Q2 (to £379.780 billion at 2010 prices) and by 0.8 per cent in 2013 Q3 billion (to £382.818 billion at 2010 prices). Compared with 2012 Q3, the output of the UK economy in 2013 Q2 is 1.5 per cent higher.

Chart 1 helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s. From it, we can see the 5-quarter recession that commenced in 1980 Q1 when output shrunk by 4.6 per cent, the 5-quarter recession that commenced in 1990 Q3 when output shrank by 2.4 per cent and the 6-quarter recession that commenced in 2008 Q2 when output shrank by 7.2 per cent. (Click here to download a PowerPoint of the chart.)

Chart 2 scratches a little below the surface by looking at output by the four principal industrial types. The interesting finding is that the output of the service sector has now risen above its 2008 Q1 peak. In 2013 Q3 output is 0.5 per cent larger. By contrast, the other three sectors remain smaller than in 2008 Q1. Agriculture, forestry and fisheries is 5.9 per cent smaller, construction 14.3 per cent smaller and production (including manufacturing) is 14.6 per cent smaller. (Click here to download a PowerPoint of the chart.)

With today’s release, quarterly growth now averages –0.11 per cent since 2008 Q2. If we take the series back to the mid 1950s when it began, the average quarterly rate of growth is 0.64 per cent which is equivalent to an annual rate of increase of 2.57 per cent. While today’s news is encouraging it remains important to keep it in perspective and to ensure that growth is sustainable and built on firm foundations.

A modern tragedy of the commons

In many parts of the world, life in the oceans is dying out. The term ‘dead zones’ is used to describe seas that are devoid of marine life. And these zones are growing in size and number.

It’s not just the decline in fish and other marine species that’s worrying environmentalists and many others; it’s a growth in rubbish. Part of this is caused by natural disasters, such as the 2011 Tsunami in Japan that washed huge amounts of debris into the Pacific Ocean. But much of it is caused by rubbish carried down rivers and into the seas, or rubbish jettisoned from ships. The problem is particularly acute in areas of the oceans where currents circulate the rubbish into huge rubbish dumps. There are two such areas either side of Hawaii in the Pacific. Both are vast.

The first article below tells the tale of Newcastle (Australia) yachtsman Ivan Macfadyen. He completed the 2013 Melbourne to Osaka double handed yacht race earlier this year as skipper of his yacht Funnelweb and then went on to bring the yacht home to Australia via America and race the famous Trans-Pac Yacht Race from Los Angeles to Hawaii along the way.

Exactly 10 years before, when [he] had sailed exactly the same course from Melbourne to Osaka, all he’d had to do to catch a fish from the ocean between Brisbane and Japan was throw out a baited line.

“There was not one of the 28 days on that portion of the trip when we didn’t catch a good-sized fish to cook up and eat with some rice,” Macfadyen recalled. But this time, on that whole long leg of sea journey, the total catch was two. No fish. No birds. Hardly a sign of life at all.

After reaching Osaka in Japan, they sailed on to San Francisco via Hawaii.

“After we left Japan, it felt as if the ocean itself was dead,” Macfadyen said. “We hardly saw any living things. We saw one whale, sort of rolling helplessly on the surface with what looked like a big tumour on its head. It was pretty sickening.”

“I’ve done a lot of miles on the ocean in my life and I’m used to seeing turtles, dolphins, sharks and big flurries of feeding birds. But this time, for 3000 nautical miles there was nothing alive to be seen.”

In place of the missing life was garbage in astounding volumes.

As economists, you should readily understand that here we have a case of over-exploited common resources – a Tragedy of the Commons of epic proportions. One ship’s rubbish may make a tiny difference, but when the cost of dumping is near zero and when the oceans are not policed, what is rational for a single ship becomes a disaster when repeated tens of thousands of times by other ships

Again, overfishing is the result of seemingly rational behaviour by crews of individual fishing boats. But as Economics (8th edition) points out on pages 328–30:

Common resources are not owned but are available free of charge to anyone. Examples include the air we breathe and the oceans for fishing. Like public goods, they are non-excludable. For example, fishing boats can take as many fish as they are able from the open seas. There is no ‘owner’ of the fish to stop them. As long as there are plentiful stocks of fish, there is no problem.

But as more people fish the seas, so fish stocks are likely to run down. This is where common resources differ from public goods. There is rivalry. One person’s use of a common resource diminishes the amount available for others. This result is an overuse of common resources. This is why fish stocks in many parts of the world are severely depleted, why virgin forests are disappearing (cut down for timber or firewood), why many roads are so congested and why the atmosphere is becoming so polluted (being used as a common ‘dump’ for emissions). In each case, a resource that is freely available is overused. This has become known as the tragedy of the commons.

… When I use a common resource, I am reducing the amount available for others. I am imposing a cost on other people: an external cost. If I am motivated purely by self-interest, I will not take these external costs into account.

Try doing some research to find out just what has been happening to the state of the oceans in recent years.
