World economy predicted to double in size by 2042

A new report by PricewaterhouseCoopers (PwC) forecasts the global economic changes between now and 2050.

The long-term power shift away from the established advanced economies is set to continue over the period to 2050, as emerging market countries boost their share of world GDP in future decades, despite recent mixed performance in some of these economies.

This is one of the key findings from the latest report by PwC economists, The long view: how will the global economic order change by 2050? This presents forecasts of GDP growth up to 2050 for 32 of the largest economies in the world, which together account for 85% of global GDP. The projections are based on an update of a detailed, long-term, global growth model, first developed by PwC in 2006.

PwC predicts that the world economy will double in size by 2042, growing at an average real rate of 2.5% annually from 2017 to 2050. This growth will be driven largely by emerging market and developing countries, with the E7 economies of Brazil, China, India, Indonesia, Mexico, Russia and Turkey growing at an annual average rate of 3.5% over the next 33 years, compared to only 1.6% for the advanced G7 nations of Canada, France, Germany, Italy, Japan, the UK and the US.

As shown in Figure 1, the E7 could comprise almost 50% of world GDP by 2050, while the G7's share declines to only just over 20%.

When looking at GDP measured at market exchange rates (MER), there is not quite such a radical shift in global economic power. But China still emerges as the largest economy in the world before 2030 and India is still clearly the third largest in the world by 2050.

But the spotlight will certainly be on the newer emerging markets as they take centre stage. By 2050, Indonesia and Mexico are projected to be larger than Japan, Germany, the UK or France, while Turkey could overtake Italy. In terms of growth, Vietnam, India and Bangladesh could be the fastest growing economies over the period to 2050, averaging growth of around 5% per year.

Nigeria has the potential to move eight places up the GDP rankings to 14th by 2050, but it will only realise this potential if it can diversify its economy away from oil and strengthen its institutions and infrastructure.

Colombia and Poland also exhibit great potential, and are projected to be the fastest growing large economies in their respective regions, Latin America and the EU (though Turkey is projected to grow faster if we consider a wider definition of Europe).

"Growth in many emerging economies will be supported by relatively fast-growing populations, boosting domestic demand and the size of the workforce," comments John Hawksworth, PwC Chief Economist and co-author of the report. "This will need, however, to be complemented with investments in education and improvement in macroeconomic fundamentals to ensure there are sufficient jobs for the growing number of young people in these countries."

One piece of good news for today's advanced economies is that they will continue to enjoy higher average incomes. With the possible exception of Italy, all of the G7 continue to sit above the E7 in the rankings of GDP per capita in 2050. Emerging markets will close this gap gradually over time, but full convergence of income levels across the world is likely to take until well beyond 2050.

China achieves a middling average income level by 2050, while India remains in the lower half of the income range given its starting point, despite relative high projected growth over time. This illustrates that while strong population growth can be a key driver of total GDP growth, it will take much longer to eliminate differences in average income levels.

"Average income gaps between countries will reduce over time, but this process will still be far from complete by 2050," explains Hawksworth. "In 2016, US GDP per capita was almost four times that of China's and almost nine times that of India's. By 2050, these gaps are projected to narrow so that average US income levels may be around double China's and around three times India's – but it is also possible that income inequality within countries will continue to rise, driven in particular by technological change that favours higher skilled workers and the owners of capital."

PwC expects global economic growth to average 3.5% per annum over the years to 2020, slowing to around 2.7% in the 2020s, 2.5% in the 2030s, and 2.4% in the 2040s. This will occur as many advanced economies (and eventually also some emerging markets like China) experience a marked decline in their working-age populations. At the same time, emerging market growth rates will moderate as these economies mature and the scope for rapid catch-up growth declines. These effects are projected to outweigh the impact of emerging economies having a progressively higher weight in world GDP, which would otherwise tend to boost average global growth.

To realise their potential, emerging economies must undertake sustained and effective investment in education, infrastructure and technology. The fall in oil prices from mid-2014 to early 2016 highlighted the importance of more diversified emerging economies for long-term sustainable growth. Underlying all of this is the need to develop the political, economic, legal and social institutions within emerging economies to generate incentives for innovation and entrepreneurship, creating secure and stable economies in which to do business.

Hawksworth continues: "Policymakers across the world face a number of challenges if they are to achieve sustainable long-term economic growth of the kind we project in this report. Structural developments – such as aging populations and climate change – require forward-thinking policy which equips the workforce to continue to make societal contributions later on in life and promotes low carbon technologies.

"Falling global trade growth, rising income inequality within many countries and increasing global geopolitical uncertainties are intensifying the need to create diversified economies which create opportunities for everyone in a broad variety of industries."

Emerging market development will create many opportunities for business. These will arise as these economies progress into new industries, open up to world markets and as their relatively youthful populations get richer. They will become more desirable places to work and live, attracting new investment and talent.

Emerging economies are rapidly evolving and often relatively volatile, however, so companies will need operating strategies that have the right mix of flexibility and patience to succeed in these markets. Case studies in the PwC report illustrate how businesses should be prepared to adjust their brand and market positions to suit differing and often more nuanced local preferences. An in-depth understanding of the local market and consumers will be crucial, which will often involve working with local partners.

John Hawksworth concludes: "Businesses need to be patient enough to ride out the short-term economic and political storms that will inevitably occur from time to time in these emerging markets as they move towards maturity. But the numbers in our report make clear that failure to engage with these emerging markets means missing out on the bulk of the economic growth we expect to see in the world economy between now and 2050."
