As the world prepares for the post-pandemic era, the quest for sustainable economic growth is becoming ever more intense – especially for developing countries. It is tempting to call for these countries – the main engine of global growth in recent decades – to shift their development strategies from industrialization to services. As new technologies increasingly allow services to be produced and traded just like goods, some economists even suggest that low-income economies should skip the manufacturing stage of development altogether and go directly from traditional agriculture to the new “growth escalator” of services.
The belief that services represent the new holy grail for developing countries stems in part from empirical studies showing that trade in services has increased faster than trade in manufactured goods since 2000, and in particular since 2011. The disruption of global value chains caused by Covid-19 has only reinforced this belief.
Moreover, new technologies like 5G networks and cloud computing are fragmenting service processes and opening up new possibilities to outsource high-wage and costly activities. These trends are driving a so-called “third unbundling”, whereby some previously non-tradable services become tradable. With the world’s largest economies engaged in tariff wars and global trade declining sharply, many regard services as the most appropriate growth and employment engine, because they can be digitized and are less susceptible to customs and other logistical barriers.
But this blind faith in services-led growth is a dangerous illusion, and the arguments supporting it are deeply flawed.
For starters, the downward trend in the global trade-to-GDP ratio over the past decade should be put in perspective: a study by Giovanni Federico and Antonio Tena-Junguito shows that although world trade since 1800 has often suffered temporary retreats, the fundamental and consistent trend is upward. Trade and globalization have on balance made the world much wealthier, and will remain the most reliable routes to global prosperity and peace.
Second, manufacturing – not services – remains the primary driver of global growth. True, high-tech innovation is blurring the lines between physical and new digital production systems, and also changing the conventional boundaries between agriculture, industry, and services. For example, new developments in information and communications technology (ICT) are allowing traditional farmers around the world to connect to global value chains in agro-industrial production and services.
But these changes do not alter the fact that industrialization is still paramount in the quest for economic prosperity. The digital revolution is mainly opening up new opportunities to accelerate innovation and boost the value-added content of manufacturing output. A recent report by the United Nations Industrial Development Organization shows that value added in world manufacturing averaged 3.1% annual growth between 1991 and 2018, slightly higher than the average GDP growth rate of 2.8%. As a result, manufacturing’s contribution to world GDP growth increased from 15.2% in 1990 to 16.4% in 2018.
Third, the current value of global trade in services is only one-third that of manufactured goods, even though services account for 75% of GDP and 80% of employment in OECD (Organization for Economic Co-operation and Development) countries. Advanced economies’ greater share of employment in tradeable services is simply a logical step in the process of industrial upgrading and structural transformation, and also reflects their comparative advantage in being near the technological frontier and relying mainly on relatively high-skilled labour and financial capital.
By contrast, developing countries’ comparative advantage is low-cost labour, and they should not seek to mimic the services-led growth strategy in vogue in advanced economies without having the skills base to sustain it. Policymakers from Bolivia to Burundi to Bhutan would be ill-advised to try to emulate Switzerland’s services-led growth simply because they also are landlocked countries.
Moreover, the claim that industrialization will create fewer job opportunities than in the past because robots are increasingly replacing human labour remains conjectural. Although automation will eliminate a large number of jobs, it will also likely create new industries and jobs in more skilled activities. Once we consider indirect effects along the value chain, the increase in the stock of robots used in global manufacturing is actually creating employment, not destroying it. Moreover, in situations where technological progress and the proliferation of artificial intelligence (AI) lead to unemployment and worsen inequality, sound public policies (such as non-distortionary taxation levied to compensate those who otherwise lose their jobs) can counter these negative effects.
Fourth, services’ status as the main source of growth in many developing countries (at least according to official national accounting statistics) mainly reflects the failures of industrialization strategies that were not aligned with these economies’ comparative advantages, as well as excessive informalization in traditional agriculture and relatively unproductive activities. Low-skilled services may help many people to escape extreme poverty, but they are not reliable engines of growth and sustainable economic development.
