Negative interest rates are fun for Governments

£30bn infrastructure programs! Ending taxation!

When bond yields are negative in real terms (as they are in Germany, the US and the UK) it leads to weird economic incentives.

Jonathan Portes has previously written about how interest rates this low mean that the government could embark on a £30bn infrastructure investment package for just the income raised each year by the now-defunct pasty tax. Portes, who is the director of the National Institute for Economic and Social Research, argued that:

If the government were, as I suggest, to fund a £30bn (2 per cent of GDP) investment programme, and fund it by borrowing through issuing long-term index-linked gilts, the cost to taxpayers - the interest on those gilts - would be something like £150m a year. . .

Twenty, or fifty, years from now, economic historians will look back at the decisions we are taking now. I cannot imagine that they will be anything but incredulous and horrified that – presented with these charts and figures – policymakers did nothing, international organisations staffed with professional economists encouraged them in their inaction, and commentators and academic economists (thankfully, few in the UK) came up with ever more tortuous justifications.

Today, Tyler Cowen argues that there is a dangerously underexamined hidden assumption in Portes' argument:

Keep in mind that the interest rates on quality government debt are down, in part, because the risk premium is up.  Non-governmental investments are perceived as riskier. . .

You might think the government investments are “low hanging fruit” in terms of quality.  Maybe yes, maybe no, but the low real interest rate doesn’t signal that, rather it signals merely that people expect to be repaid.

In this argument for more government investment, the notion of government investments as low hanging fruit is doing a lot of the work.

Cowen doesn't seem to be taking a fair approach to the situtation. Government investments aren't low hanging fruit so much as all other investments are unfeasibly risky. The long-term usefulness of transport, energy or education infrastructure, for instance, is little changed due to the current economic climate, so the multiplier for investment in them remains the same as it ever was.

But if investment in infrastructure is too risky, Matt Yglesias suggests another use for negative real interest rates: Stop collecting taxes. Yes, all of them:

Normally you face a tradeoff. Taxes impose costs on the present-day population that might impair wealth creation over the long-term, but to avoid taxes by borrowing you need to pay interest to creditors.

But the real interest rate we're being asked for is low. Less than zero. So what's the tradeoff?

Why not sell as many negative-yield ten-year bonds as the market will buy (sell enough bonds and presumably interest rates will rise) and let that auction revenue "crowd out" taxes as a way of financing government activities?

The really interesting thing about such a plan would be seeing the political fallout. In so many economic arguments, taxation, spending and size of government are used interchangably; lefties like big government, high taxes, and high spending, and right-wingers the opposite. But put a massive disconnect between the taxing and spending sides of government, and who knows which side of the line people will fall? Are the Taxpayers Alliance in favour of low taxes or small government? What about David Cameron?

MPs Seema Malhotra and Stephen Kinnock lay out a 6-point plan for Brexit:

Time for Theresa May to lay out her priorities and explain exactly what “Brexit means Brexit” really means.

Angela Merkel has called on Theresa May to “take her time” and “take a moment to identify Britain’s interests” before invoking Article 50. We know that is code for the “clock is ticking” and also that we hardly have any idea what the Prime Minister means by “Brexit means Brexit.”

We have no time to lose to seek to safeguard what is best in from our membership of the European Union. We also need to face some uncomfortable truths.

Yes, as remain campaigners we were incredibly disappointed by the result. However we also recognise the need to move forward with the strongest possible team to negotiate the best deal for Britain and maintain positive relationships with our nearest neighbours and allies. 
 
The first step will be to define what is meant by 'the best possible deal'. This needs to be a settlement that balances the economic imperative of access to the single market and access to skills with the political imperative to respond to the level of public opinion to reduce immigration from the EU. A significant proportion of people who voted Leave on 23 June did so due to concerns about immigration. We must now acknowledge the need to review and reform. 

We know that the single market is founded upon the so-called "four freedoms", namely the free movement of goods, capital, services and people & labour. As things stand, membership of the single market is on an all-or-nothing basis. 

We believe a focus for negotiations should be reforms to how the how the single market works. This should address how the movement of people and labour across the EU can exist alongside options for greater controls on immigration for EU states. 

We believe that there is an appetite for such reforms amongst a number of EU governments, and that it is essential for keeping public confidence in how well the EU is working.

So what should Britain’s priorities be? There are six vital principles that the three Cabinet Brexit Ministers should support now:

1. The UK should remain in the single market, to the greatest possible extent.

This is essential for our future prosperity as a country. A large proportion of the £17 billion of foreign direct investment that comes into the UK every year is linked to our tariff-free access to a market of 500 million consumers. 

Rather than seeking to strike a "package deal" across all four freedoms, we should instead sequence our approach, starting with an EU-wide review of the freedom of movement of people and labour. This review should explore whether the current system provides the right balance between consistency and flexibility for member states. Indeed, for the UK this should also address the issue of better registration of EU nationals in line with other nations and enforcement of existing rules. 

If we can secure a new EU-wide system for the movement of people and labour, we should then seek to retain full access to the free movement of goods, capital and services. This is not just in our interests, but in the interests of the EU. For other nation states to play hardball with Britain after we have grappled first with the complexity of the immigration debate would be to ignore rather than act early to address an issue that could eventually lead to the end of the EU as we know it.

2. In order to retain access to the single market we believe that it will be necessary to make a contribution to the EU budget.

Norway, not an EU member but with a high degree of access to the single market, makes approximately the same per capita contribution to the EU budget as the UK currently does. We must be realistic in our approach to this issue, and we insist that those who campaigned for Leave must now level with the British people. They must accept that if the British government wishes to retain access to the single market then it must make a contribution to the EU budget.

3. The UK should establish an immigration policy which is seen as fair, demonstrates that we remain a country that is open for business, and at the same time preventing unscrupulous firms from undercutting British workers by importing cheap foreign labour.  

We also need urgent confirmation that EU nationals who were settled here before the referendum as a minimum are guaranteed the right to remain, and that the same reassurance is urgently sought for Britons living in mainland Europe. The status of foreign students from the EU at our universities must be also be clarified and a strong message sent that they are welcomed and valued. 

4. The UK should protect its financial services industry, including passporting rights, vital to our national prosperity, while ensuring that the high standards of transparency and accountability agreed at an EU level are adhered to, alongside tough new rules against tax evasion and avoidance. In addition, our relationship with the European Investment Bank should continue. Industry should have the confidence that it is business as usual.

5. The UK should continue to shadow the EU’s employment legislation. People were promised that workers’ rights would be protected in a post-Brexit Britain. We need to make sure that we do not have weaker employment legislation than the rest of Europe.

6. The UK should continue to shadow the EU’s environmental legislation.

As with workers’ rights, we were promised that this too would be protected post-Brexit.  We must make sure we do not have weaker legislation on protecting the environment and combatting climate change. We must not become the weak link in Europe.

Finally, it is vital that the voice of Parliament and is heard, loud and clear. In a letter to the Prime Minister we called for new joint structures – a Special Parliamentary Committee - involving both Houses to be set up by October alongside the establishment of the new Brexit unit. There must be a clear role for opposition parties. It will be equally important to ensure that both Remain and Leave voices are represented and with clearly agreed advisory and scrutiny roles for parliament. Representation should be in the public domain, as with Select Committees.

However, it is also clear there will be a need for confidentiality, particularly when sensitive negotiating positions are being examined by the committee. 

We call for the establishment of a special vehicle – a Conference or National Convention to facilitate broader engagement of Parliament with MEPs, business organisations, the TUC, universities, elected Mayors, local government and devolved administrations. 

The UK’s exit from the EU has dominated the political and economic landscape since 23 June, and it will continue to do so for many years to come. It is essential that we enter into these negotiations with a clear plan. There can be no cutting of corners, and no half-baked proposals masquerading as "good old British pragmatism". 

The stakes are far too high for that.
