One of the key questions about Brexit is its effect on UK trade and cross-border investment. Once outside the customs union, will the freedom to negotiate trade deals lead to an increase in UK exports and GDP, as many who support Brexit claim; or will the increased frictions in trade with the EU, and the need to negotiate new trade deals with those non-EU countries which already have trade deals with the EU, lead to a fall in exports and in GDP?

Also, how will trade restrictions or new trade deals affect capital flows? Will there be an increase in inward investment or a flight of investment to the EU or elsewhere? Will many companies relocate away from the UK – or to it?

Although there has been a cost up to now from the Brexit vote, in terms of a depreciation in sterling and a fall in inward investment (see the first article below), the future effects have been hard to predict as the terms on which the UK will leave the EU have been unclear. However, with a draft withdrawal agreement between the EU and the UK government having been reached, the costs and benefits are becoming clearer. But there is still uncertainty about just what the effects on trade and investment will be.

  • First, the 585-page draft withdrawal agreement is not a trade deal. It contains details of UK payments to the EU, commitments on the rights of EU and UK citizens and confirmation of the transition period – initially until 31 December 2020, but possibly extended with mutual agreement. During the transition agreement, the UK would remain a member of the customs union and single market and remain subject to rulings of the European Court of Justice. The withdrawal agreement also provides for a continuation of the customs union beyond the transition period, if no long-term trade agreement is in place. This is to prevent he need for a hard border between Ireland and Northern Ireland.
  • Second, there is merely a 26-page ‘political declaration‘ about future trade relations. Negotiations on the details of these can only begin once the UK has left the EU, scheduled for 29 March 2019. So it’s still unclear about just how free trade in both goods and services will be between the UK and the EU and how freely capital and labour will move between them. But with the UK outside the single market, there will be some limitations on trade and factor movements – some frictions.
  • Third, it is not clear whether the UK Parliament will agree to the withdrawal agreement. Currently, it seems as if a majority of MPs is in favour of rejecting it. If this happens, will the UK leave without an agreement, with trade based on WTO terms? Or will the EU be prepared to renegotiate it – something it currently says it will not do? Or will the issue be put back to the electorate in the form of a People’s vote (see also), which might contain the option of seeking to remain in the EU?

So, without knowing just what the UK’s future trade relations will be with (a) the EU, (b) non-EU countries which have negotiated trade deals with the EU, (c) other countries without trade deals with the EU, it is impossible to quantify the costs and benefits from the effects on trade and investment. However, the consensus among economists is still that there will be a net cost in terms of lost trade and inward investment.

Such as view is backed by a government analysis of various Brexit scenarios, released in time for the House of Commons vote on 11 December. This concludes that the UK will be worse off under all Brexit alternatives compared with staying in the EU. The main brake on growth will be frictions in trade from tariff and non-tariff barriers.

This analysis was supported by a Bank of England paper which modelled various scenarios based on assumptions about different types of Brexit deal. While recognising the inherent uncertainty in some of the empirical relationships, it still concluded that Brexit would be likely to have a net negative effect. The size of this negative effect would depend on the closeness of the new relationship between the UK and EU, the degree of preparedness across firms and critical infrastructure, and how other policies respond.

An agreement in principle was reached on September 30 between the USA, Canada and Mexico over a new trade deal to replace the North American Free Trade Agreement (NAFTA). President Trump had described NAFTA as ‘the worst trade deal maybe ever signed anywhere, but certainly ever signed in this country.’ The new deal, named the United States-Mexico-Canada Agreement, or USMCA, is the result of 14 months of negotiations, which have often been fractious. A provisional bilateral agreement was made between the USA and Mexico in August. At the same time, President Trump threatened a trade war with Canada if it did not reach a trade agreement with the USA (and Mexico). The new USMCA must be ratified by lawmakers in all three countries before it can come into force. This could take a few months.

So is USMCA a radical departure from NAFTA? Does the USA stand to gain substantially, as President Trump claims? In fact, USMCA is little different from NAFTA. It could best be described as a relatively modest reworking of NAFTA. So what are the changes?

The first change affects the car industry. From 2020, 75% of the components of any vehicle crossing between the USA and Canada or Mexico must be made within one or more of the three countries to qualify for tariff-free treatment. The aim is to boost production within the region. But the main change here is merely an increase in the proportion from the current 62.5%.

A more significant change affecting the car industry concerns wages. Between 40% and 45% of a vehicle’s components must be made by workers earning at least US$16 per hour. This is some three times more than the average wage currently earned by Mexican car workers. Although it will benefit such workers, it will reduce Mexico’s competitive advantage and could hence lead to some diversion of production away from Mexico. Also, it could push up the price of cars.

The agreement has also strengthened various standards inadequately covered in NAFTA. According to The Conversation article:

The new agreement includes stronger protections for patents and trademarks in areas such as biotech, financial services and domain names – all of which have advanced considerably over the past quarter century. It also contains new provisions governing the expansion of digital trade and investment in innovative products and services.
 
Separately, negotiators agreed to update labor and environmental standards, which were not central to the 1994 accord and are now typical in modern trade agreements. Examples include enforcing a minimum wage for autoworkers, stricter environmental standards for Mexican trucks and lots of new rules on fishing to protect marine life.

Another area where the USMCA agreement has made changes concerns trade in dairy products. This particularly affects Canada, which has agreed to allow more US dairy products tariff-free into Canada (see the CNN article at the end of the list of articles below). New higher quotas will give US dairy farmers access to 3.6% of Canada’s dairy market. They will still pay tariffs on dairy exports to Canada that exceed the quotas, ranging from 200% to 300%.

The other significant change for consumers in Mexico and Canada is a rise in the value of duty-free imports they can bring in from the USA, including online transactions. As the first BBC article listed below states:

The new agreement raises duty-free shopping limits to $100 to enter Mexico and C$150 ($115) to enter Canada without facing import duties – well above the $50 previously allowed in Mexico and C$20 permitted by Canada. That’s good news for online shoppers in Mexico and Canada – as well as shipping firms and e-commerce companies, especially giants like Amazon.

Despite these changes, USMCA is very similar to NAFTA. It is still a preferential trade deal between the three countries, but certainly not a completely free trade deal – but nor was NAFTA.

And for the time being, US tariffs on Mexican and Canadian steel and aluminium imports remain in place. Perhaps, with the conclusion of the USMCA agreement, the Trump administration will now, as promised, consider lifting these tariffs.

I admit it, the title of my blog today is a little bit misleading – but at the same time very appropriate for today’s topic. Nancy Sinatra certainly wasn’t thinking about emigration when she was singing this song – it had nothing to do with it, after all. It is, however, very relevant to economists: Indeed, there are many economics papers discussing the effects of skilled immigration on host and source economies and regions.

Economists often use the term ‘brain drain’ to describe the migration of highly skilled workers from poor/developing to rich/developed economies. Such flows are anything but unusual. As The Economist points out in a recent article, ‘[I]n the decade to 2010–11 the number of university-educated migrants in the G20, a group of large economies that hosts two-thirds of the world’s migrants, grew by 60% to 32m according to the OECD, a club of mostly rich countries.’.

The effects of international migration are found to be overwhelmingly positive for both skilled migrant workers and their hosts. This is particularly true for highly skilled workers (such as academics, physicians and other professionals), who, through emigration, get the opportunity to earn a significantly higher return on their skills that what they might have had in their home country. Very often their home country is saturated and oversupplied with skilled workers competing for a very limited number of jobs. Also, they get the opportunity to practise their profession – which they might not have had otherwise.

But what about their home countries? Are they worse off for such emigration?

There are different views when it comes to answering this question. One argument is that the prospect of international migration incentivises people in developing countries to accumulate skills (brain gain) – which they might not choose to do otherwise, if the expected return to skills was not high enough to warrant the effort and opportunity cost that comes with it. Beine et al (2011) find that:

Our empirical analysis predicts conditional convergence of human capital indicators. Our findings also reveal that skilled migration prospects foster human capital accumulation in low-income countries. In these countries, a net brain gain can be obtained if the skilled emigration rate is not too large (i.e. it does not exceed 20–30% depending on other country characteristics). In contrast, we find no evidence of a significant incentive mechanism in middle-income, and not surprisingly, high-income countries.

Other researchers find that emigration can have a significant negative effect on source economies (countries or regions) – especially if it affects a large share of the local workforce within a short time period. Ha et al (2016), analyse the effect of emigration on human capital formation and economic growth of Chinese provinces:

First, we find that permanent emigration is conducive to the improvement of both middle and high school enrollment. In contrast, while temporary emigration has a significantly positive effect on middle school enrollment it does not affect high school enrollment. Moreover, the different educational attainments of temporary emigrants have different effects on school enrollment. Specifically, the proportion of temporary emigrants with high school education positively affects middle school enrollment, while the proportion of temporary emigrants with middle school education negatively affects high school enrollment. Finally, we find that both permanent and temporary emigration has a detrimental effect on the economic growth of source regions.

So yes or no? Good or bad? As everything else in economics, the answer quite often is ‘it depends’.

Donald Trump has threatened to pull out of the World Trade Organization. ‘If they don’t shape up, I would withdraw from the WTO,’ he said. He argues that the USA is being treated very badly by the WTO and that the organisation needs to ‘change its ways’.

Historically, the USA has done relatively well compared with other countries in trade disputes brought to the WTO. However, President Trump does not like being bound by an international organisation which prohibits the unilateral imposition of tariffs that are not in direct retaliation against a trade violation by other countries. Such tariffs have been imposed by the Trump administration on steel and aluminium imports. This has led to retaliatory tariffs on US imports by the EU, China and Canada – something that is permitted under WTO rules.

Whether or not the USA does withdraw from the WTO, Trump’s threats bring into question the power of the WTO and other countries’ compliance with WTO rules. With the rise in protectionist sentiments around the world, the power of the WTO would seem to be on the wane.

Even if the USA does not withdraw from the WTO, it is succeeding in weakening the organisation. Appeals cases have to be heard by an ‘appellate body’, consisting of at least three judges drawn from a list of seven, each elected for four years. But the USA has the power to block new appointees – and has done so. As Larry Elliott states in the first article below:

The list of judges is already down to four and will be down to the minimum of three when the Mauritian member, Shree Baboo Chekitan Servansing, retires at the end of September. Two more members will go by the end of next year, at which point the appeals process will come to a halt.

This raises the question of the implication of a ‘no-deal’ Brexit – something that seems more likely as the UK struggles to reach a trade agreement with the EU. Leaving without a deal would mean ‘reverting to WTO rules’. But if these rules are being ignored by powerful countries such as the USA and possibly China, and if the appeals procedure has ground to a halt, this could leave the UK without the safety net of international trade rules. Outside the EU – the world’s most powerful trade bloc – the UK could find itself having to accept poor trade terms with the USA and other large countries.

The Economist is probably not the kind of newspaper that you will read more than once per issue – certainly not two years after its publication date. That is because, by definition, financial news articles are ephemeral: they have greater value, the more recent they are – especially in the modern financial world, where change can be strikingly fast. To my surprise, however, I found myself reading again an article on inequality that I had first read two years ago – and it is (of course) still relevant today.

The title of the article was ‘You may be higher in the global wealth pyramid than you think’ and it discusses exactly that: how much wealth does it take for someone to be considered ‘rich’? The answer to this question is of course, ‘it depends’. And it does depend on which group you compare yourself against. Although this may feel obvious, some of the statistics that are presented in this article may surprise you.

According to the article

If you had $2200 to your name (adding together your bank deposits, financial investments and property holdings, and subtracting your debts) you might not think yourself terribly fortunate. But you would be wealthier than half the world’s population, according to this year’s Global Wealth Report by the Crédit Suisse Research Institute. If you had $71 560 or more, you would be in the top tenth. If you were lucky enough to own over $744 400 you could count yourself a member of the global 1% that voters everywhere are rebelling against.

For many (including yours truly) these numbers may come as a surprise when you first see them. $2200 in today’s exchange rate is about £1640. And this is wealth, not income – including all earthly possessions (net of debt). £1640 of wealth is enough to put you ahead of half of the planet’s population. Have a $774 400 (£556 174 – about the average price of a two-bedroom flat in London) and – congratulations! You are part of the global richest 1% everyone is complaining about…

Such comparisons are certainly thought provoking. They show how unevenly wealth is distributed across countries. They also show that countries which are more open to trade are more likely to have benefited the most from it. Take a closer look at the statistics and you will realise that you are more likely to be rich (compared to the global average) if you live in one of these countries.

Of course, wealth inequality does not happen only across countries – it happens also within countries. You can own a two-bedroom flat in London (and be, therefore, part of the 1% global elite), but having to live on a very modest budget because your income (which is a flow variable, as opposed to wealth, which is a stock variable) has not grown fast enough in relation to other parts of the national population.

Would you be better off if there were less trade? Certainly not – you would probably be even poorer, as trade theories (and most of the empirical evidence I am aware of) assert. Why do we then talk so much about trade wars and trade restrictions recently? Why do we elect politicians who advocate such restrictions? It is probably easier to answer these questions using political than economic theory (although game theory may have some interesting insights to offer – have you heard of the ‘Chicken game‘?). But as I am neither political scientists nor a game theorist, I will just continue to wonder about it.
