Investment set to fall as business is baffled by Trump

Economic growth is closely linked to investment. In the short term, there is a demand-side effect: higher investment, by increasing aggregate demand, creates a multiplier effect. GDP rises and unemployment falls. Over the longer term, higher net investment causes a supply-side effect: industrial capacity and potential output rise. This will be from both the greater quantity of capital and, if new investment incorporates superior technology, from a greater productivity of capital.

One of the biggest determinants of investment is certainty about the future: certainty allows businesses to plan investment. Uncertainty, by contrast, is likely to dampen investment. Investment is for future output and if the future is unknown, why undertake costly investment? After all, the cost of investment is generally recouped over several months or year, not immediately. Uncertainty thus increases the risks of investment.

There is currently great uncertainty in the USA and its trading partners. The frequent changes in policy by President Trump are causing a fall in confidence and consequently a fall in investment. The past few weeks have seen large cuts in US government expenditure as his administration seeks to dismantle the current structure of government. The businesses supplying federal agencies thus face great uncertainty about future contracts. Laid-off workers will be forced to cut their spending, which will have knock-on effect on business, who will cut employment and investment as the multiplier and accelerator work through.

There are also worries that the economic chaos caused by President Trump’s frequent policy changes will cause inflation to rise. Higher inflation will prompt the Federal Reserve to raise interest rates. This, in turn, will increase the cost of borrowing for investment.

Tariff uncertainty

Perhaps the biggest uncertainty for business concerns the imposition of tariffs. Many US businesses rely on imports of raw materials, components, equipment, etc. Imposing tariffs on imports raises business costs. But this will vary from firm to firm, depending on the proportion of their inputs that are imported. And even when the inputs are from other US companies, those companies may rely on imports and thus be forced to raise prices to their customers. And if, in retaliation, other countries impose tariffs on US goods, this will affect US exporters and discourage them from investing.

For many multinational companies, whether based in the USA or elsewhere, supply chains involve many countries. New tariffs will force them to rethink which suppliers to use and where to locate production. The resulting uncertainty can cause them to delay or cancel investments.

Uncertainty has also been caused by the frequent changes in the planned level of tariffs. With the Trump administration using tariffs as a threat to get trading partners to change policy, the threatened tariff rates have varied depending on how trading partners have responded. There has also been uncertainty on just how the tariff policy will be implemented, making it more difficult for businesses to estimate the effect on them.

Then there are serious issues for the longer term. Other countries will be less willing to sign trade deals with the USA if they will not be honoured. Countries may increasingly look to diverting trade from the USA to other countries.

How cross-border electricity trade can supercharge Africa’s energy transition

Africa’s energy transition is at a pivotal moment. While the continent boasts abundant renewable energy resources, its electricity generation and distribution remain fragmented. Cross-border electricity trade has emerged as a potential game-changer, fostering energy security, reducing costs, and accelerating the adoption of renewables. However, is Africa fully leveraging this opportunity?

In a forthcoming paper in the Energy & Environment journal, I join forces with my colleagues Mercy Adaji and Bereket Kebede to argue that the answer to this question is no. Our study examines the impact of cross-border electricity trade in renewable electricity generation across 21 African countries over a 24-year period (1996–2020). Our findings indicate that a 1% increase in electricity trade significantly raises the share of renewables in total electricity output by approximately 0.05%. This underscores the crucial role of regional integration in advancing Africa’s clean energy goals, aligning with previous studies (e.g., Boz et al., 2021; Song et al., 2022, linked below) that highlight how electricity market integration promotes renewable energy investments by stabilising supply and mitigating intermittency risks.

Despite these advantages, cross-border electricity trade remains significantly underutilised due to regulatory barriers, inadequate infrastructure, and governance challenges.

Net electricity-importing countries tend to benefit more from trade, while net-exporting nations, particularly those reliant on fossil fuels, exhibit weaker positive impacts. Without targeted policies (such as carbon pricing and green subsidies) trade disparities may persist, slowing the transition to clean energy.

Moreover, our results highlight the pivotal role of governance in fostering a robust electricity market. This is neither surprising nor new – quality of governance matters over the long term in all aspects of economic activity. Agostini et al. (2019), for instance, show that well-structured regulations and strategic investments in interconnections enhance the effectiveness of cross-border electricity trade. Transparent regulatory frameworks, expanded grid interconnections, and harmonised energy policies can significantly boost the impact of regional electricity trade.

By strengthening collaboration, African nations can mitigate energy poverty, enhance supply reliability, and accelerate the shift toward a greener future.

To capitalise fully on cross-border electricity trade, African policymakers must prioritise regional energy integration, invest in infrastructure and implement incentives to spur renewable energy expansion. With the right policies and co-operative strategies, Africa can harness its vast renewable potential and achieve a more sustainable, energy-secure future.

‘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 Russian economy after two years of war

It’s two years since Russia invaded Ukraine. Western countries responded by imposing large-scale sanctions. These targeted a range of businesses, banks and other financial institutions, payments systems and Russian exports and imports. Some $1 trillion of Russian assets were frozen. Many Western businesses withdrew from Russia or cut off commercial ties. In addition, oil and gas imports from Russia have been banned by most developed countries and some developing countries, and a price cap of $60 per barrel has been imposed on Russian oil. What is more, sanctions have been progressively tightened over the past two years. For example, on the second anniversary of the invasion, President Biden announced more than 500 new sanctions against individuals and companies involved in military production and supply chains and in financing Russia’s war effort.

The economy in Russia has also been affected by large-scale emigration of skilled workers, the diversion of workers to the armed forces and the diversion of capital and workers to the armaments industry.

So has the economy of Russia been badly affected by sanctions and these other factors? The IMF in its World Economic Forecast of April 2022 predicted that the Russian economy would experience a steep, two-year recession. But, the Russian economy has fared much better than first predicted and the steep recession never materialised.

In this blog we look at Russia’s economic performance. First, we examine why the Russian economy seems stronger today than forecast two years ago. Then we look at its economic weaknesses directly attributable to the war.

Apparent resilience of the Russian economy

GDP forecasts have proved wrong. In April 2022, just after the start of the war, the IMF was forecasting that the Russian economy would decline by 8.5% in 2022 and by 2.3% in 2023 and grow by just 1.5% in 2024. In practice, the economy declined by only 1.2% in 2022 and grew by 3.0% in 2023. It is forecast by the IMF to grow by 2.6% in 2024. This is illustrated in the chart (click here for a PowerPoint).

Similarly, inflation forecasts have proved wrong. In April 2022, Russian consumer price inflation was forecast to be 21.3% in 2022 and 14.3% in 2023. In practice, inflation was 13.8% in 2022 and 7.4% in 2023. What is more, consumer spending in Russia has remained buoyant. In 2023, retail sales rose by 10.2% in nominal terms – a real rise of 2.8%. Wage growth has been strong and unemployment has remained low, falling from just over 4% in February 2022 to just under 3% today.

So why has the Russian economy seemingly weathered the war so successfully?

The first reason is that, unlike Ukraine, very little of its infrastructure has been destroyed. Even though it has lost a lot of its military capital, including 1120 main battle tanks and some 2000 other armoured vehicles, virtually all of its production capacity remains intact. What is more, military production is replacing much of the destroyed vehicles and equipment.

The second is that its economy started the war in a strong position economically. In 2021, it had a surplus on the current account of its balance of payments of 6.7% of GDP, reflecting large revenues from oil, gas and mineral exports. This compares with a G7 average deficit of 0.7%. It had fiscal surplus (net general government lending) of 0.8% of GDP. The G7 countries had an average deficit of 9.1% of GDP. Its gross general government debt was 16% of GDP. The G7’s was an average of 134%. This put Russia in a position to finance the war and gave it a considerable buffer against economic sanctions.

The third reason is that Russia has been effective in switching the destinations of exports and sources of imports. Trade with the West, Japan and South Korea has declined, but trade with China and various neutral countries, such as India have rapidly increased. Take the case of oil: in 2021, Russia exported 4.4 billion barrels of oil per day to the USA, the EU, the UK, Japan and South Korea. By 2023, this had fallen to just 0.6 billion barrels. By contrast, in 2021, it exported 1.9 billion barrels per day to China, India and Turkey. By 2023, this had risen to 4.9 billion. Although exports of natural gas have fallen by around 42% since 2021, Russian oil exports have remained much the same at around 7.4 million barrels per day (until a voluntary cut of 0.5 billion barrels per day in 2024 Q1 as part of an OPEC+ agreement to prop up the price of oil).

China is now a major supplier to Russia of components (some with military uses), commercial vehicles and consumer products (such as cars and electrical goods). Total trade with China (both imports and exports) was worth $147 billion in 2021. By 2023, this had risen to $240 billion.

The use of both the Chinese yuan and the Russian rouble (or ruble) has risen dramatically as a means of payment for Russian imports. Their share has risen from around 5% in 2021 (mainly roubles) to nearly 75% in 2023 (just over 37% in each currency). Switching trade and payment methods has helped Russia to circumvent many of the sanctions.

The fourth reason is that Russia has a strong and effective central bank. It has successfully used interest rates to control inflation, which is expected to fall from 7.4% in 2023 to under 5% this year and then to its target of 4% in subsequent years. The central bank policy rate was raised from 8.5% to 20% in February 2022. It then fell in steps to 7.5% in September 2022, where it remained until August 2023. It was then raised in steps to peak at 16% in December 2023, where it remains. There is a high level of confidence that the Russian central bank will succeed in bringing inflation back to target.

The fifth reason is that the war has provided a Keynesian stimulus to the economy. Military expenditure has doubled as a share of GDP – from 3.7% of GDP in 2021 to 7.5% in 2024. It now accounts for around 40% of government expenditure. The boost that this has given to production and employment has helped achieve the 3% growth rate in 2023, despite the dampening effect of a tight monetary policy.

Longer-term weaknesses

Despite the apparent resilience of the economy, there are serious weaknesses that are likely to have serious long-term effects.

There has been a huge decline in the labour supply as many skilled and professional workers have move abroad to escape the draft and as many people have been killed in battle. The shortage of workers has led to a rise in wages. This has been accompanied by a decline in labour productivity, which is estimated to have been around 3.6% in 2023.

Higher wages and lower productivity is putting a squeeze on firms’ profits. This is being exacerbated by higher taxes on firms to help fund the war. Lower profit reduces investment and is likely to have further detrimental effects on labour productivity.

Although Russia has managed to circumvent many of the sanctions, they have still had a significant effect on the supply of goods and components from the West. As sanctions are tightened further, so this is likely to have a direct effect on production and living standards. Although GDP is growing, non-military production is declining.

The public finances at the start of the war, as we saw above, were strong. But the war effort has turned a budget surplus of 0.8% of GDP in 2021 to a deficit of 3.7% in 2023 – a deficit that will be difficult to fund with limited access to foreign finance and with domestic interest rates at 16%. As public expenditure on the military has increased, civilian expenditure has decreased. Benefits and expenditure on infrastructure are being squeezed. For example, public utilities and apartment blocks are deteriorating badly. This has a direct on living standards.

In terms of exports, although by diverting oil exports to China, India and other neutral countries Russia has manage to maintain the volume of its oil exports, revenue from them is declining. Oil prices have fallen from a peak of $125 per barrel in June 2022 to around $80 today. Production from the Arabian Gulf is likely to increase over the coming months, which will further depress oil prices.

Conclusions

With the war sustaining the Russian economy, it would be a problem for Russia if the war ended. If Russia won by taking more territory in Ukraine and forcing Ukraine to accept Russia’s terms for peace, the cost to Russia of rebuilding the occupied territories would be huge. If Russia lost territory and negotiated a settlement on Ukraine’s terms, the political cost would be huge, with a disillusioned Russian people facing reduced living standards that could lead to the overthrow of Putin. As The Conversation article linked below states:

A protracted stalemate might be the only solution for Russia to avoid total economic collapse. Having transformed the little industry it had to focus on the war effort, and with a labour shortage problem worsened by hundreds of thousands of war casualties and a massive brain drain, the country would struggle to find a new direction.
