The new economics: what does this mean for liberals?

My previous article on the changing world of political economy generated more interest than usual. It was, of course, a small dip into a large and complex topic. Given the interest shown, I feel the need to expand on it a bit.

The first thing to say is that what I am calling “the new economics” is based on standard economic principles, and the ideas aren’t new. The departure from political policy norms may be radical, but the departure from mainstream economic theory is not. This is partly how I have chosen to frame it. The heterodox idea of Modern Monetary Theory (MMT), popular in some parts of the left in the US and UK, is in fact not at all far from my new economics. But MMT advocates have, generally, chosen to frame their arguments as a radical challenge to conventional economics, and have a tendency to be very rude about mainstream economists. They have in turn drawn lots of rude comments from mainstream economists. A lot of this dispute, from both sides, is manufactured and I think that is a pity. Clearly some facts are in dispute, but it would be better to narrow these down and focus on the evidence rather than indulge in slanging.

Instead I take inspiration from people who are clearly on the mainstream spectrum. The main one is Adair Turner (whom I found going through some of my old papers was a Cambridge contemporary of mine: we were both members of the Conservative Association in 1976-1979). I haven’t read anything more than the Economist review of Dietrich Vollrath’s Fully Grown: Why a Stagnant Economy is a Sign of Success, but he is clearly another mainstream economist developing the same sorts of ideas. Mr Vollrath’s contribution is to bring rigorous numerical analysis to the table, where I have been plying with airy ideas.

Which brings me to my next point. A modern, developed economy will not show much in the way of GDP growth. We have become so conditioned to thinking that growth is a sign of economic health that this takes a lot of getting used to. But it is perfectly consistent with human wellbeing advancing. People may consume less stuff per head, but they can still have increasing levels of physical and mental wellbeing, and live in a nicer, friendlier and healthier environment. Mainstream economists have a tendency to suggest that people are being irrational if they consume less, work less, buy organic vegetables and have a healthier lifestyle, but the irrationality is theirs.

But a “stagnant” economy does bring a problem in its wake, and that problem is taxes and funding the public sector. GDP measures the size of the money economy, and the money economy is central to way governments operate. Indeed you can make a good case that money was invented so that the state could organise armies, build infrastructure and hoard surplus food. While the state could, and did, do this through forced labour and the appropriation of harvests and other goods, a system of taxation and wages is much more flexible. The rival idea that money was invented to facilitate trade is harder to sustain, though it used to feature a lot in economics text books. Of course the two functions of money, taxation and trade, fed off each other in a virtuous circle.

This all matters because there is no sign that the role of the state (in the broadest sense of collective public action) is about to diminish. The expansion of the state is one of the most important developments of the 20th Century, starting in large part with the creation of war economies, and then a dramatic expansion of the state role in education, healthcare and pensions and other welfare payments. To many on the right, this expansion of the state is seen as a hideous intrusion on human freedom that needs to be reversed. In fact it is a response to two important developments. The first is the tendency of capitalism to self-destruction, as noted by Karl Marx. If the capitalists succeed in creating too much profit, which is then hoarded, fewer people will benefit from the possibilities that the economy offers, and the system stagnates and collapses. If the state taxes those profits and hands them out to the less well off, this creates demand for capitalism’s products and the system is saved. (This is not the only way: capitalists being more generous with paying their workers has a similar effect, though it usually it takes organised labour to make this happen).

The second development causing the increased size of the state is the good old Baumol effect, which is the main driver of the new economics. The private sector is becoming so efficient that the relative cost of public goods is rising compared to what gets traded in private markets. Everything is more expensive in defence, law enforcement and healthcare. This issue is getting more acute. Public services are generally overstretched and many of their employees are underpaid. Stinginess on welfare benefits is creating knock-on problems elsewhere in society.

But this creates a political challenge. Public services need to be funded through taxes (it is possible to have a theological debate on this with MMT advocates, but let me duck that for now – without taxation public spending leads to inflation). People are generally willing to pay quite a bit of tax, but this comes at a political cost. Politicians have tried to sidestep this through economic growth. If the money economy is growing, then the state collects more money while keeping the tax rates the same. Those familiar with Baumol thinking will realise that this always was flawed thinking, as productivity in the public sector lags that in the private sector. But now we are in the stagnant phase of our economic evolution, the argument collapses completely.

That points to the raising of taxes, and all the political problems that come with that. But behind this there is a bit of a puzzle. For now state budget deficits look quite sustainable, as do higher levels of state borrowing. The fear is that deficit spending will create inflation, and high levels of public debt create financial instability – and that the risks are higher if the economy isn’t growing. But there is no sign that inflation is close to be awakened in developed economies, while monetary policy can be used to manage high levels of government debt, provided that you are borrowing in your own currency, and inflation is dormant. Meanwhile private sector demand for public debt remains very healthy. So just when do we need those higher taxes?

That is the central problem at the heart of the modern political economy. I don’t have an answer. But longer term there are three important things about a liberal approach to the new economics that I do hold on to:

  1. The government’s extra flexibility on fiscal deficits and debt should be exploited through investment programmes, creating assets that can be separately financed if necessary. These include social housing and renewable energy infrastructure. We need to be more careful with hospitals and transport infrastructure, but there are doubtless opportunities there too.
  2. The day when extra taxes will be needed to fund more public services will arrive. When it does the level of public accountability will need to improve substantially. This points to the need for a profound devolution of power, and especially the power to raise taxes, backed up greatly improved public governance.
  3. Meanwhile public services will need to be more efficient and effective (which is not the same as being more productive in my vocabulary). That means a profound switch to preventing and solving problems rather than service delivery and ticking boxes. That will require specialised services to work in a much more integrated way with much more delegated authority – and that means that services. mainly, need to be more localised. Which, of course, fits neatly with point 2.

I think this could be the basis for a grand bargain between liberals and either the left or, even, the right. The signs that either end of the political spectrum, or indeed liberals, are up for this are mixed. But there are some stirrings. On the other hand unscrupulous forces of the right or left could exploit the extra flexibility on public finances to line their friends’ pockets and consolidate political control while pretending to address the needs of “ordinary people”.

The rules of political economy have changed. Mainstream politicians and commentators haven’t noticed

Before the great financial crash of 2007-2008 there was a solid consensus as to the sorts of economic policies governments should pursue. In fact the underlying realities have been changing for some time. These new realities now dominate in developed economies, and yet the political mainstream hasn’t caught up. It is one of the reasons that populist politicians, not least Donald Trump, are doing relatively well when they defy the old rules.

What were those rules? First is that GDP growth is a critical indicator of economic wellbeing, and that increased productivity is the driver of this. Politicians should push through “supply-side” policies that improve productivity, which will allow income per head to grow, and with it individual incomes and wellbeing. With productivity apparently in the doldrums since the crash, especially here in Britain, there is much shaking of heads. Before the crash economists had thought something they referred to as “trend growth” of about 2% per annum was practically a law of nature. Many still think its disappearance is a failure of policy.

Second, governments must maintain a prudent fiscal policy that does not allow high levels of public debt to pile up. Public spending must be paid for through higher taxes. High levels of public debt can destabilise an economy, it was thought. This went alongside the idea that if public spending was not restrained it would be wasted, and cause low productivity.

Third: free trade is essential to a healthy economy. This follows from basic economics: the principle of comparative advantage. During the years of rapid globalisation of trade from the 1980s to the early 2000s, this idea received a terrific boost as new Asian economies entered the mix, with comparative advantage particularly evident in basic manufacturing. This generated huge gains in trade for both developed and developing economies.

And fourth, interest rate policy is the right way to manage the business cycle to ensure that recessions were smoothed out. This replaced the older post-war idea that fiscal policy was the right way to do this. Interest rate policy (or “monetary policy”) allowed the private sector to expand and contract as required, through an efficient market mechanism, rather than inefficient government direction.

What changed? First of all, the conventional wisdom on monetary policy, which evolved after the old system of fixed exchange rates and capital controls, known as Bretton Woods, collapsed in the early 1970s, led to an explosion of private debt. While policy makers liked to think that the policy was sustainable, there was a clear trend towards higher private debt and lower interest rates. This contributed to the great financial crash. Now interest levels can’t go lower, and people worry more about financial stability. This means that monetary policy is pretty much done for as means of regulating the cycle, with fiscal policy coming back into the picture, sometimes disguised as monetary policy with such ideas as “quantitative easing”.

Perhaps the most important change, though, was that productivity in manufactured and other tradable goods has advanced so far that they have ceased to have such an important role in the economy as a whole. This is known as the Baumol effect, and it is something I have been banging on about for ages. The modern economy is in fact dominated by things like health care, social care, and services, with status goods and land also playing a larger overall role. The old conventional wisdom around productivity doesn’t really work here.

On top of this environmental degradation, and especially climate change is posing a question that was always there. Is producing and consuming more and more stuff actually advancing human wellbeing? We all need to eat and wear clothes, but do we need to get through quite so much as we do? And yet an economic mindset in which consuming stuff is central to the way we measure wellbeing refuses to die.

A couple of other factors are worth mentioning. First is that the Asian economies are developing fast and converging with the western developed ones. This means that there are fewer gains from trade available, and that the globalisation boom is over; indeed many of those gains will actually reverse as the two worlds converge and comparative advantage diminishes. Second modern industry is not as hungry for capital investment as it used to be. This is partly to do with the Baumol effect, as the relative size of capital intensive industry shrinks, but also to do with the nature of modern technology, which uses more human capital. There are fewer opportunities in the private sector for savings to invest in, at any rate for things that aren’t outright speculative. The main cause of the great crash was an excess of private sector speculation as the relative scale of productive investment diminished.

So what does all this mean? First that it is OK to play fast and loose with fiscal policy. High levels of public debt are quite sustainable because the availability of private investment is diminished. Public debt is safer than private speculation. This is clearly evident in the USA and Japan. In Britain it is a little less clear because the country has a high current account deficit, meaning that is more vulnerable to international changes of mood – but surely there is much more scope than the government is currently using. Second, it is much less damaging than before to play fast and loose with trade policy. Once again Donald Trump is taking full advantage of this. His trade policy is mostly economic nonsense, but he can get away with it. Likewise Brexit is likely to be less dire for Britain than many predict – though the potential upside for “global Britain” is very slim. Trade just doesn’t matter so much, and the opportunities in Asia are disappearing.

All this is good news for populists. Mainstream policy needs to catch up. Policymakers need to drop their obsession with GDP and productivity, and start looking at wider quality of life instead. This includes the prevalence of poverty (I prefer not to focus on inequality, though that is clearly part of the picture), mental health problems and the environment. There needs to be a bigger drive on public investment, but not so much on roads, railways and airports, but on hospitals and healthcare therapies, social housing, and sustainable energy. There is scope for increased private investment here too, but the public element is vital.

There are other ideas, such as universal basic income, though I personally don’t favour this. But a rethink of state benefits is surely important. My instinct is for stronger set of social interventions to reduce poverty and its malign effects, rather than trying to make the problem go away by spraying money everywhere.

How does this work politically? It should be an opportunity for the left. And indeed Britain’s Labour manifesto in last election wasn’t quite as daft as it looked – in theory anyway. Bernie Sanders is making headway in the US in spite of defying conventional wisdom. But politics isn’t just about economics, and the left don’t really seem to grasp the demand for increasing personal autonomy. Besides so much of leftwing activism seems to be a rage against efficiency. Productivity may be an overrated issue, but the need for efficient and effective services remains as vital as ever.

Liberals, meanwhile, are badly compromised by their attachment to the old conventional wisdom. They have not yet found a new vision. Personally I think there is an opportunity for a grand bargain between the left and liberals, but there is no clear sign of this emerging. Meanwhile the political right has a clear opportunity. In the US they seem to be wasting it by failing to recognise that an efficient and effective state is critical to the future. They are failing to face up to the challenge on healthcare and the environment. In the UK the picture is different. The Conservatives are interested in courting more liberal-minded voters, and have not abandoned the idea of reducing carbon emissions, for example, or investing more in healthcare.

But at the moment the new rules of economics are providing more opportunities for the unscrupulous than they are to those genuinely want to make the world a better place. it is no wonder that the political centre is in such a mess.
