Buses are about redistribution, productivity and a greener future




Labour’s policy for buses is a key part of reversing the impact of neoliberalism on transport since the 1980s. It is redistributive: it helps those who cannot afford to drive to work. Nearly half of all bus journeys are taken by those who have no car, and two thirds of those who travel on buses have an annual income below £25,000 per annum. But it is also a brave policy. By far the most popular mode of transport is by car (or van), and the policy will be portrayed by opponents as putting road building at risk. .


The money recently promised by Labour will mainly go to undoing another impact of austerity. Outside London fares on commercial routes are set by bus operators. Local authorities can provide subsidies for routes that are socially important but not commercially viable. Local authority-supported services outside London have halved in vehicle mileage since 2009 as austerity has squeezed local authority budgets.


But Labour also plan to change the way buses are run outside London. Bus operation was privatised by Mrs Thatcher in 1986. Yet privatisation has in most cases failed to bring the benefits of competition. Largely as a result of a long-term process of consolidation through merger and acquisition, the UK bus industry is highly concentrated with three businesses (Arriva, FirstGroup, and Stagecoach) dominating the sector. Head-to-head competition between operators is uncommon, producing what is effectively a monopoly.

The market failure in this case may be the ability of a large bus operator to stifle any competition by temporarily cutting prices or increasing frequency. That makes the routes unprofitable for a time for the large bus company, but it is also unprofitable for the new entrant. As the financial resources available to the big company are much greater, they have the ability to kill off or take over any competition.There is no regulator preventing this kind of unfair competition.

With new entry unlikely to happen because of the possibility of such threats, the large bus companies can do what every unregulated monopoly does: raise fares and reduce services. That is good for profits and dividends, but bad for passengers. The large bus companies make good profits, and the passenger gets a more expensive or less frequent service. Since 2009, for example, the average price of riding a bus has increased in real terms by over 15%, while the cost of using a car in real terms has hardly changed.

There is a vicious circle here. The cost of running a bus is largely independent of how many people use it, so if usage declines firms put prices up, which in turn discourages passengers. But one important area has seen bus use rise rather than decline, and that is London.

The system in London is rather different from the rest of the country. Contrary to common belief, Transport for London does not own its buses. What it can do that local authorities elsewhere cannot is set routes and fares, with private companies bidding to run each route. That avoids the high fares that come from monopoly, and it also makes it easy to establish a common ticketing system which is absent in places like Manchester. The system used in many European countries for their bus services is similar to London. An important advantage London has is that there is effective competition between bus companies to bid for tenders on routes, which helps keep costs down and maintains efficiency that might be lost in a completely nationalised system.

The success of London compared to most other areas of the country suggests the neoliberal ideal of a bus system free from government ‘interference’ does not work, and local control over routes and fares can provide a better service. It is a classic example of where economics, which recognises the social costs of monopoly, beats a neoliberal ideology that is often blind to the dangers of monopoly. This is why Labour also plan to encourage areas outside London to re-regulate bus services, and support the creation of municipal bus companies that are publicly run.

While a comparison between London and elsewhere shows the dangers of private monopolies charging too high a price for services, is there not a danger that if local government can set fares it will tend to set fares too low? I don’t think this is likely to be a major issue because of two other problems (what economists call externalities) with a profit-based bus service. If people use many cars rather than a single bus this increases congestion and pollution.

Anyone familiar with large towns and cities during rush hour will know what a nightmare congestion can be. Buses can reduce congestion by persuading people not to use their cars. Basic economics tells us that the congestion externality justifies subsidising bus travel or taxing cars. Exactly the same point applies to CO2 emissions and pollution. In this respect underpricing bus travel can be advantageous.

Unfortunately the experience of UK cities suggest that cheap fares alone may not be enough to prevent congestion. In addition congestion outside London may be having a serious impact on the productivity of our cities, as well as increasing pollution and CO2 emissions.

Tom Forth writes about a recent study that starts with a puzzle. In many countries large cities tend to be more productive than small cities, and economists explain this by talking about agglomeration effects. However this pattern does not seem to be true for the UK if you exclude London. Another way of putting the same point is that UK cities outside London are not as productive as they should be.

The study then looks at transport times to the centre of Birmingham, where the transport system is mainly based on buses. At peak times, when congestion is high, bus journey times into work can double on bad days, and anyone using a bus route has to plan for bad days. So if we think about the effective size of Birmingham in terms of a reasonable time to get to the centre, the city shrinks substantially.

This study shows that as long as cars are free to come into the centre those travelling on buses also suffer. Birmingham is using this study to target investment in bus lanes, which provides a partial answer. Park and ride schemes can help too. Another approach is to again follow London and introduce a congestion charge, but this will only be politically feasible if alternatives are easy, cheap, frequent and reliable.

If we look at cities in France, the big difference with UK cities is metros. Lyon has 4 lines, while Lille and Marseille have two lines each. Birmingham and Manchester have none. Last week I visited the French city of Rennes, population 215,000, that has one metro and is building another. Manchester has a good tram network similar to Lyon, but Birmingham has just one and Leeds none (compared to three in Marseille and two in Lille).

In short, cities outside London lack the transport infrastructure that can make them work productively, but also in a way that reduces CO2 emissions and other forms of pollution. One difference with France is how money is provided. In France every city larger than 100,000 people has a ten-year transport plan, with significant national investment in five-year allocations with ten-year strategies. In the UK cities are good at the strategies and visions but cannot secure funding to realise them.

Once you have well functioning cities you need to provide easy connections to nearby towns. Towns flourish when they are well connected to dynamic cities. Many will argue that this kind of local investment is money better spent than HS2, but I don’t think we should think of these as alternatives. Cities that link quickly to other cities are likely to be more productive, and France’s TGV network puts the UK to shame. The UK has underinvested in non-road transport infrastructure outside London for decades, and we need to make up for this quickly to create a more prosperous and greener future.

Will Brexit make austerity worse?


There seems to be some confusion among some on the left about the impact of Brexit. Statements like ‘Brexit will make austerity worse’ by Remainers are imprecise, so let me spell this out. Because of the controversy this generates I’m afraid this is going to be a rather dry, analytical post. But if you think government spending can somehow reverse the negative economic impacts of Brexit, this post is for you.

Brexit will reduce UK trade relative to what it would be if we stayed in the EU. How much will depend on the type of Brexit. As I outlined here, it will not be possible to come near to replacing that trade through new trade deals. So less trade is a given.

Less trade reduces GDP mainly because it reduces productivity. Trade allows specialisation. Instead of Honda cars being produced in each EU country they can be made in just one, which allows (in part because of what economists call economies of scale) the cars to be produced more efficiently. Trade also increases competition (you can buy many makes of car in the UK) which improves efficiency. Therefore if you restrict trade, you reduce productivity. Less productivity means less GDP. I discussed how much GDP could fall under May’s preferred trade arrangement here.

A reduction in productivity is a supply side decline in GDP. It is very different from a demand deficient recession of the kind we had after the GFC. In a demand deficit recession fiscal policy (more government spending or lower taxes) can be used to restore demand and therefore GDP, and must be used if interest rates are stuck at their lower bound. The tragedy of austerity from 2010 is that the opposite was done. The decline in GDP brought about by lower productivity following less trade cannot be tackled in that way.

When GDP falls, taxes fall. To keep the deficit constant, that requires a reduction in government spending. Brexit will reduce government spending compared to what it would be if we stayed in the EU. To that extent Brexit makes austerity worse. To say that those who point this out are advocating a continuation of the policy of 2010 austerity are wrong.

It is important to note that what I am doing here is comparing two states of the economy, and saying what the differences would be between those two states. This type of comparison confuses many people. I am not saying government spending is going to be lower than it is now - it almost certainly will not be. People say cannot we do something to mitigate the impact on GDP of Brexit? There are many things that can be done to improve GDP, like more public investment, but they could also be done if we stayed in the EU. If you think there is still spare capacity in the economy then GDP can be raised by fiscal or monetary policy, but that is equally true in or out of the EU.

Does government spending have to lower out of the EU compared to inside the EU? The answer is no, which is why statements like Brexit will make austerity worse are incomplete. You could keep government spending at the same level in and outside the EU. But that would raise the deficit, which requires higher taxes. So in that case Brexit would increase taxes. So a correct statement would be that Brexit either reduces government spending or raises taxes or some combination of the two.

At this point you get MMTers up in arms. The deficit does not matter for a country with its own currency and so on. Or even worse, that government spending determines taxes and not the other way around. This is a very good illustration of how misleading MMT rhetoric can be. To see why, go back to the case where government spending falls in proportion to GDP under Brexit, which means the deficit is unaffected by Brexit. Now suppose you increased government spending to the level it would have been without Brexit. That is an expansionary fiscal policy, which stimulates demand which raises inflation. The obvious way to reduce demand and inflation is to raise taxes so the deficit is back to its original level. It does not matter whether you need to keep the deficit unchanged because you have a fiscal rule, or you have fiscal policy stabilising the economy as MMT advocates, you get the same result.

Some MMT followers never admit they are wrong, so I got a lot of stuff about how you can use other measures to reduce inflation like credit controls. But you could use them if we stayed in the EU as well to allow higher government spending or less taxes. There is no obvious reason why leaving the EU makes such measure more effective.

The correct statement about the impact of Brexit on the public finances is that it means government spending will be lower or taxes higher or some combination of the two. Furthermore the overwhelming majority of economists think GDP will fall as a result of Brexit, and I have not come across an academic whose field is trade economics who thinks otherwise. If you think, as I do, that this government has reduced public spending way beyond the level that people want, and therefore you want to raise that spending, Brexit makes that more difficult. .
