‘Tariff is the most beautiful word.’ Not for economists!

In an interview with Joe Rogan for his podcast, The Joe Rogan Experience, just before the US election, Donald Trump stated that, “To me, the most beautiful word – and I’ve said this for the last couple of weeks – in the dictionary today and any is the word ‘tariff’. It’s more beautiful than love; it’s more beautiful than anything. It’s the most beautiful word. This country can become rich with the use, the proper use of tariffs.”

President-elect Trump has stated that he will impose tariffs on imports of 10% or 20%, with 60% and 100% tariffs on imports from China and Mexico, respectively. This protection for US industries, combined with lighter regulation, will, he claims, provide a stimulus to the economy and help create jobs. The revenues will also help to reduce America’s budget deficit.

But it is not that straightforward.

Problems with tariffs for the USA

Imposing tariffs is likely to reduce international trade. But international trade brings net benefits, which are distributed between the participants according to the terms of trade. This is the law of comparative advantage.

In the simple two-country case, the law states that, provided the opportunity costs of producing various goods differ between the two countries, both of them can gain from mutual trade if they specialise in producing (and exporting) those goods that have relatively low opportunity costs compared with the other country. The total production and consumption of the two countries will be higher.

So if the USA has a comparative advantage in various manufactured products and a trading partner has a comparative advantage in tropical food products, such as coffee or bananas, both can gain by specialisation and trade.

If tariffs are imposed and trade is thereby reduced between the USA and its trading partners, there will be a net loss, as production will switch from lower-cost production to higher-cost production. The higher costs of less efficient production in the USA will lead to higher prices for those goods than if they were imported.

At the same time, goods that are still imported will be more expensive as the price will include the tariff. Some of this may be borne by the importer, meaning that only part of the tariff is passed on to the consumer. The incidence of the tariff between consumer and importer will depend on price elasticities of demand and supply. Nevertheless, imports will still be more expensive, allowing the domestically-produced substitutes to rise in price too, albeit probably by not so much. According to work by Kimberly Clausing and Mary E Lovely for the Peterson Institute (see link in Articles below), Trump’s proposals to raise tariffs would cost the typical American household over $2600 a year.

The net effect will be a rise in inflation – at least temporarily. Yet one of Donald Trump’s pledges is to reduce inflation. Higher inflation will, in turn, encourage the Fed to raise interest rates, which will dampen investment and economic growth.

Donald Trump tends to behave transactionally rather than ideologically. He is probably hoping that a rapid introduction of tariffs will then give the USA a strong bargaining position with foreign countries to trade more fairly. He is also hoping that protecting US industries by the use of tariffs, especially when coupled with deregulation, will encourage greater investment and thereby faster growth.

Much will depend on how other countries respond. If they respond by raising tariffs on US exports, any gain to industries from protection from imports will be offset by a loss to exporters.

A trade war, with higher tariffs, will lead to a net loss in global GDP. It is a negative sum game. In such a ‘game’, it is possible for one ‘player’ (country) to gain, but the loss to the other players (countries) will be greater than that gain.

Donald Trump is hoping that by ‘winning’ such a game, the USA could still come out better off. But the gain from higher investment, output and employment in the protected industries would have to outweigh the losses to exporting industries and from higher import prices.

The first Trump administration (2017–21), as part of its ‘America First’ programme, imposed large-scale tariffs on Chinese imports and on steel and aluminium from across the world. There was wide-scale retaliation by other countries with tariffs imposed on a range of US exports. There was a net loss to world income, including US GDP.

Problems with US tariffs for the rest of the world

The imposition of tariffs by the USA will have considerable effects on other countries. The higher the tariffs and the more that countries rely on exports to the USA, the bigger will the effect be. China and Mexico are likely to be the biggest losers as they face the highest tariffs and the USA is a major customer. In 2023, US imports from China were worth $427bn, while US exports to China were worth just $148bn – only 34.6% of the value of imports. The percentage is estimated to be even lower for 2024 at around 32%. In 2023, China’s exports to the USA accounted for 12.6% of its total exports; Mexico’s exports to the USA accounted for 82.7% of its total exports.

It is possible that higher tariffs could be extended beyond China to other Asian countries, such as Vietnam, South Korea, Taiwan, India and Indonesia. These countries typically run trade surpluses with the USA. Also, many of the products from these countries include Chinese components.

As far as the UK is concerned, the proposed tariffs would cause significant falls in trade. According to research by Nicolò Tamberi at the University of Sussex (see link below in Articles):

The UK’s exports to the world could fall by £22 billion (–2.6%) and imports by £1.4 (–0.16%), with significant variations across sectors. Some sectors, like fishing and petroleum, are particularly hard-hit due to their high sensitivity to tariff changes, while others, such as textiles, benefit from trade diversion as the US shifts demand away from China.

Other badly affected sectors would include mining, pharmaceuticals, finance and insurance, and business services. The overall effect, according to the research, would be to reduce UK output by just under 1%.

Countries are likely to respond to US tariffs by imposing their own tariffs on US imports. World Trade Organization rules permit the use of retaliatory tariffs equivalent to those imposed by the USA. The more aggressive the resulting trade war, the bigger would be the fall in world trade and GDP.

The EU is planning to negotiate with Trump to avoid a trade war, but officials are preparing the details of retaliatory measures should the future Trump administration impose the threatened tariffs. The EU response is likely to be strong.

The growth of autarky: is globalisation dead?

Over the decades, economies have become increasingly interdependent. This process of globalisation has involved a growth in international trade, the spread of technology, integrated financial markets and international migration.

When the global economy is growing, globalisation spreads the benefits around the world. However, when there are economic problems in one part of the world, this can spread like a contagion to other parts. This was clearly illustrated by the credit crunch of 2007–8. A crisis that started in the sub-prime market in the USA soon snowballed into a worldwide recession. More recently, the impact of Covid-19 on international supply chains has highlighted the dangers of relying on a highly globalised system of production and distribution. And more recently still, the war in Ukraine has shown the dangers of food and fuel dependency, with rapid rises in prices of basic essentials having a disproportionate effect on low-income countries and people on low incomes in richer countries.

Moves towards autarky

So is the answer for countries to become more self-sufficient – to adopt a policy of greater autarky? Several countries have moved in this direction. The USA under President Trump pursued a much more protectionist agenda than his predecessors. The UK, although seeking new post-Brexit trade relationships, has seen a reduction in trade as new barriers with the EU have reduced UK exports and imports as a percentage of GDP. According to the Office for Budget Responsibility’s November 2022 Economic and Fiscal Outlook, Brexit will result in the UK’s trade intensity being 15 per cent lower in the long run than if it had remained in the EU.

Many European countries are seeking to achieve greater energy self-sufficiency, both as a means of reducing reliance on Russian oil and gas, but also in pursuit of a green agenda, where a greater proportion of energy is generated from renewables. More generally, countries and companies are considering how to reduce the risks of relying on complex international supply chains.

Limits to the gains from trade

The gains from international trade stem partly from the law of comparative advantage, which states that greater levels of production can be achieved by countries specialising in and exporting those goods that can be produced at a lower opportunity cost and importing those in which they have a comparative disadvantage. Trade can also lead to the transfer of technology and a downward pressure on costs and prices through greater competition.

But trade can increase dependence on unreliable supply sources. For example, at present, some companies are seeking to reduce their reliance on Taiwanese parts, given worries about possible Chinese actions against Taiwan.

Also, governments have been increasingly willing to support domestic industries with various non-tariff barriers to imports, especially since the 2007–8 financial crisis. Such measures include subsidies, favouring domestic firms in awarding government contracts and using regulations to restrict imports. These protectionist measures are often justified in terms of achieving security of supply. The arguments apply particularly starkly in the case of food. In the light of large price increases in the wake of the Ukraine war, many countries are considering how to increase food self-sufficiency, despite it being more costly.

Also, trade in goods involves negative environmental externalities, as freight transport, whether by sea, air or land, involves emissions and can add to global warming. In 2021, shipping emitted over 830m tonnes of CO2, which represents some 3% of world total CO2 emissions. In 2019 (pre-pandemic), the figure was 800m tonnes. The closer geographically the trading partner, the lower these environmental costs are likely to be.

The problems with a globally interdependent world have led to world trade growing more slowly than world GDP in recent years after decades of trade growth considerably outstripping GDP growth. Trade (imports plus exports) as a percentage of GDP peaked at just over 60% in 2008. In 2019 and 2021 it was just over 56%. This is illustrated in the chart (click here for a PowerPoint). Although trade as a percentage of GDP rose slightly from 2020 to 2021 as economies recovered from the pandemic, it is expected to have fallen back again in 2022 and possibly further in 2023.

But despite this reduction in trade as a percentage of GDP, with de-globalisation likely to continue for some time, the world remains much more interdependent than in the more distant past (as the chart shows). Greater autarky may be seen as desirable by many countries as a response to the greater economic and political risks of the current world, but greater autarky is a long way from complete self-sufficiency. The world is likely to remain highly interdependent for the foreseeable future. Reports of the ‘death of globalisation’ are premature!

UK–Australia trade deal: benefits and costs

The UK and Australia are set to sign a free-trade deal at the G7 summit in Cornwall on 11–13 June. This will eventually give tariff-free access to each other’s markets, with existing tariffs being phased out over a 15-year period. It is the first trade deal not based on an existing EU template. The government hopes that it will be followed by trade deals with other countries, including New Zealand, Canada and, crucially, the USA.

But what are the benefits and costs of such a deal?

Trade and comparative advantage

The classic economic argument is that free trade allows countries to benefit from the law of comparative advantage. According to the law, provided opportunity costs of various goods differ in two countries, both of them can gain from mutual trade if they specialise in producing (and exporting) those goods that have relatively low opportunity costs compared with the other country. In the case of the UK and Australia, the UK has a comparative advantage in products such as financial services and high-tech and specialist manufactured products. Australia has a comparative advantage in agricultural products, such as lamb, beef and wheat and in various ores and minerals. By increasing trade in these products, there can be a net efficiency gain to both sides and hence a higher GDP than before.

There is clearly a benefit to consumers in both countries from cheaper products, but the gains are likely to be very small. The most optimistic estimate is that the gain in UK GDP will be around 0.01% to 0.02%. Part of the reason is the physical distance between the two countries. For products such as meat, grain and raw materials, shipping costs could be relatively high. This might result in no cost advantage over imports from much nearer countries, such as EU member states.

But modern trade deals are less about tariffs, which, with various WTO trade rounds, are much lower than in the past. Many imports from Australia are already tariff free, with meat currently having a tariff of 12%. Modern trade deals are more about reducing or eliminating non-tariff barriers, such as differing standards and regulations. This is the area where there is a high degree of concern in the UK. Import-competing sectors, such as farming, fear that their products will be undercut by Australian imports produced to lower standards.

Costs of a trade deal

In a perfectly competitive world, with no externalities, labour mobile between sectors and no concerns about income distribution, eliminating tariffs would indeed provide an efficiency gain. But these conditions do not hold. Small farmers are often unable to compete with food producers with considerable market power. The danger is that by driving out such small farmers, food production and supply might not result in lower long-run prices. Much would depend on the countervailing power of supermarkets to continue bearing down on food costs.

But the question of price is probably the least worrying issue. Meat and grain is generally produced at lower standards in Australia than in the UK, with various pesticides, fertilisers and antibiotics being used that are not permitted in the UK (and the EU). Unless the trade deal can involve UK standards being enforced on products produced in Australia for export to the UK, UK farmers could be undercut by such imports. The question then would be whether labelling of imported food products could alert consumers to the different standards. And even if they did, would consumers simply prefer to buy the cheaper products? If so, this could be seen as a market failure with consumers not taking into account all the relevant health and welfare costs. Better quality food could be seen as a merit good.

Then there are the broader social issues of the protection of rural industries and societies. Labour is relatively immobile from farming and there could be a rise in rural unemployment, which could have local multiplier effects, leading to the decline of rural economies. Rural ways of life could be seriously affected, which imposes costs on local inhabitants and visitors.

Trade itself imposes environmental costs. Even if it were privately efficient to transport products half way around the world, the costs of carbon emissions and other pollution may outweigh any private gains. At a time when the world is becoming increasingly concerned about climate change, and with the upcoming COP26 conference in Glasgow in November, it is difficult to align such a trade deal with a greater commitment to cutting carbon emissions.

A free-trade deal? Not really

According to the Brexit trade agreement (the Trade and Cooperation Agreement (TCA)), trade between the EU and the UK will remain quota and tariff free. ‘Quota free’ means that trade will not be restricted in quantity by the authorities on either side. ‘Tariff free’ means that customs duties will not be collected by the UK authorities on imports from the EU nor by the EU authorities on imports from the UK.

Article ‘GOODS .5: Prohibition of customs duties’ on page 20 of the agreement states that:

Except as otherwise provided for in this Agreement, customs duties on all goods originating in the other Party shall be prohibited.

This free-trade agreement was taken by many people to mean that trade would be unhindered, with no duties being payable. In fact, as many importers and exporters are finding, trade is not as ‘free’ as it was before January 2021. There are four sources of ‘friction’.

Tariffs on goods finished in the UK

This has become a major area of concern for many UK companies. When a good is imported into the UK from outside the EU and then has value added to it by processing, packaging, cleaning, remixing, preserving, refashioning, etc., under ‘rules of origin’ regulations, it can only count as a UK good if sufficient value or weight is added. The proportions vary by product, but generally goods must have approximately 50% UK content (or 80% of the weight of foodstuffs) to qualify for tariff-free access to the EU. For example, for a petrol car, 55% of its value must have been created in either the EU or UK. Thus cars manufactured in the UK which use many parts imported from Japan, China or elsewhere, may not qualify for tariff-free access to the EU.

In other cases, it is simply the question of whether the processing is deemed ‘sufficient’, rather than the imported inputs having a specific weight or value. For example, the grinding of pepper is regarded as a sufficient process and thus ground pepper can be exported from the UK to the EU tariff free. Another example is that of coal briquettes:

The process to transform coal into briquettes (including applying intense pressure) goes beyond the processes listed in ‘insufficient processing’ and so the briquettes can be considered ‘UK originating’ regardless of the originating status of the coal used to produce the briquettes.

In the case of many garments produced in the UK and then sold in retail chains, many of which have branches in both the UK and EU, generally both the weaving and cutting of fabric to make garments, as well as the sewing, must take place in the UK/EU for the garments to be tariff free when exported from the UK to the EU and vice versa.

Precise details of rules of origin are given in the document, The Trade and Cooperation Agreement (TCA): detailed guidance on the rules of origin.

Many UK firms exporting to the EU and EU firms exporting to the UK are finding that their products are now subject to tariffs because of insufficient processing being done in the UK/EU. Indeed, with complex international supply chains, this is a major problem for many importing and exporting companies.

Documentation

Rules of origin require that firms provide documentation itemising what parts of their goods come from outside the UK/EU. Then it has to be determined whether tariffs will be necessary on the finished product. This is time consuming and is an example of the increase in ‘red tape’ about which many firms are complaining. As the Evening Standard article states:

Exporters have to be able to provide evidence to prove the origin of their products’ ingredients. Next year, they will also have to provide suppliers’ declarations too, and EU officials may demand those retrospectively, so exporters need to have them now.

The increased paperwork and checks add to the costs of trade. Some EU companies are stating that they will no longer export to the UK and some UK companies that they will no longer export to the EU, or will have to set up manufacturing plants or distribution hubs in the EU to handle trade within the EU.

Other companies are adding charges to their products to cover the costs. As the Guardian article states:

“We bought a €47 [£42] shelf from Next for our bathroom,” said Thom Basely, who lives in Marseille. “On the morning it was supposed to be delivered we received an ‘import duty/tax’ demand for over €30, like a ransom note. It came as a complete surprise.”

In evidence given to the Treasury Select Committee (Q640) in May 2018, Sir Jon Thompson, then Chief Executive of HMRC, predicted that leaving the single market would involve approximately 200 million extra customs declarations on each side of the UK/EU border at a cost of £32.50 for each one, giving a total extra cost of approximately £6.5bn on each side of the border for companies trading with Europe. Although this was only an estimate, the extra ‘paperwork’ will represent a substantial cost.

VAT

Previously, goods could be imported into the UK without paying VAT in the UK on value added up to that point as VAT had already been collected in the EU. Similarly, goods exported to the EU would already have had VAT paid and hence would only be subject to the tax on additional value added. The UK was part of the EU VAT system and did not have to register for VAT in each EU country.

Now, VAT has to be paid on the goods as they are imported or released from a customs warehouse – similar to a customs duty. This is therefore likely to involve additional administration costs – the same as those with non-EU imports.

Services

The UK is a major exporter of services, including legal, financial, accounting, IT and engineering. It has a positive trade in services balance with the EU, unlike its negative trade in goods balance. Yet, the Brexit deal does not include free trade in services. Some of the barriers to other non-EU countries have been reduced for the UK in the TCA, but UK service providers will still face new barriers which will impose costs. For example, some EU countries will limit the time that businesspeople providing services can stay in their countries to six months in any twelve. Some will not recognise UK qualifications, unlike when the UK was a member of the single market.

The financial services supplied by City of London firms are a major source of export revenue, with about 40% of these revenues coming from the EU. Now outside the single market, these firms have lost their ‘passporting rights’. These allowed such firms to sell their services into the EU without the need for additional regulatory clearance. The alternative now is for such firms to be granted ‘equivalence’ by the EU. This has not yet been negotiated and even if it were, does not cover the full range of financial services. It excludes, for example, banking services such as lending and deposit taking.

Conclusions

Leaving the single market has introduced a range of frictions in trade. These are causing severe problems to some importers and exporters in the short term. Some EU goods are now unavailable in the UK or only so at significantly higher prices. Some exporters are finding that the frictions are too great to make their exports profitable. However, it remains to be seen how quickly accounting and logistical systems can adjust to improve trade flows between the UK and the EU.

But some of these frictions, as itemised above, will remain. According to the law of comparative advantage, these restrictions on trade will lead to a loss of GDP. And these losses will not be spread evenly throughout the UK economy: firms and their employees which rely heavily on UK–EU trade will be particularly hard hit.

EU strikes major trade deals

The EU has recently signed two trade deals after many years of negotiations. The first is with Mercosur, the South American trading and economic co-operation organisation, currently consisting of Brazil, Argentina, Uruguay and Paraguay – a region of over 260m people. The second is with Vietnam, which should result in tariff reductions of 99% of traded goods. This is the first deal of its kind with a developing country in Asia. These deals follow a recent landmark deal with Japan.

At a time when protectionism is on the rise, with the USA involved in trade disputes with a number of countries, such as China and the EU, deals to cut tariffs and other trade restrictions are seen as a positive development by those arguing that freer trade results in a net gain to the participants. The law of comparative advantage suggests that trade allows countries to consume beyond their production possibility curves. What is more, the competition experienced through increased trade can lead to greater efficiency and product development.

It is estimated that the deal with Mercosur could result in a saving of some €4bn per annum in tariffs on EU exports.

But although there is a net economic gain from greater trade, some sectors will lose as consumers switch to cheaper imports. Thus the agricultural sector in many parts of the EU is worried about cheaper food imports from South America. What is more, increased trade could have detrimental environmental impacts. For example, greater imports of beef from Brazil into the EU could result in more Amazonian forest being cut down to graze cattle.

But provided environmental externalities are internalised within trade deals and provided economies are given time to adjust to changing demand patterns, such large-scale trade deals can be of significant benefit to the participants. In the case of the EU–Mercosur agreement, according to the EU Reporter article, it:

…upholds the highest standards of food safety and consumer protection, as well as the precautionary principle for food safety and environmental rules and contains specific commitments on labour rights and environmental protection, including the implementation of the Paris climate agreement and related enforcement rules.

The size of the EU market and its economic power puts it in a strong position to get the best trade deals for its member states. As EU Trade Commissioner, Cecilia Malmström stated:

Over the past few years the EU has consolidated its position as the global leader in open and sustainable trade. Agreements with 15 countries have entered into force since 2014, notably with Canada and Japan. This agreement adds four more countries to our impressive roster of trade allies.

Outside the EU, the UK will have less power to negotiate similar deals.
