The Growth Engines Are Sputtering

The International Monetary Fund’s significant downward revision to its 2022 World Economic Outlook, just one quarter into the calendar year, has generated headlines and hand-wringing around the world. But no less important is the dour forecast for 2023, which implies a broader crisis of prevailing growth models.

CAMBRIDGE – The International Monetary Fund’s revised World Economic Outlook (WEO) is sobering. It is rare for the organization to revise down sharply its projections for economic growth just one quarter into the calendar year. Yet in this case, it has done so for 86% of its 190 member countries, resulting in a decline of almost one percentage point in global growth for 2022 – from 4.4% to 3.6%. Moreover, this forecast is accompanied by a significant increase in projected inflation, and all this bad news is packaged in a wrapping of deeper uncertainty. There is a downward bias in the balance of risks, and inequality is expected to worsen both within and across countries.

But as important as these 2022 effects are, especially when it comes to the impact on vulnerable segments of the population and fragile countries, we also must pay attention to the IMF’s 2023 outlook. The projection for next year points to a medium-term problem that is no less important: the lost potency of growth models worldwide. The IMF does not expect its significant downward revision in global economic growth for 2022 to be offset in 2023. Instead, it has lowered its forecast for next year from 3.8% to 3.6%, with those revisions applying to both advanced and developing economies.

The implication is that the world’s economic engines are sputtering. This problem is especially worrisome in such a fluid operating environment, because it means that the prevailing growth models are not up to the task of pulling economies through unanticipated negative shocks. Making matters worse, the same models have also failed to maintain a decent level of inclusive growth during periods of less stress.

Three major secular developments are to blame for the tepid outlook: the changing nature of globalization; the prolonged reliance on artificial growth boosters; and the long-term failure to invest in the sources of sustained growth.

Economic and financial globalization have been evolving in ways that make it more difficult for national economies to leverage international trade and foreign direct investment for domestic growth. While the pandemic raised questions about the proliferation and potential vulnerabilities of “just-in-time” cross-border supply chains, it is worth recalling that trade and investment restrictions were increasing well before COVID-19 emerged. The US-China trade war featured the return of high tariffs and other protectionist measures that have generated far-reaching knock-on effects throughout the global economy.

Moreover, these developments have come at a time when many countries face tighter policy constraints. A return to conventional and unconventional monetary-policy stimulus is now precluded by high and persistent inflation. As the IMF notes, this new environment confronts central banks with very delicate and problematic policy tradeoffs, and it exposes the real economy to the potential vagaries of financial-market volatility.

Although the scope for fiscal action is less limited than it is for monetary measures, it is not well distributed among countries. While governments should use the firepower they have to protect the most vulnerable segments of their populations, some already face troubling debt levels.

These developments coincide with a period of low productivity growth in many countries, which is a function of past and persistent failures to invest in the drivers of genuine growth, including physical infrastructure and human capital.

The IMF’s report offers an important reminder to policymakers that they need to focus much more attention on generating innovation, improving productivity, and strengthening the other drivers of robust, inclusive economic growth. Failure to do so will make the risk of medium-term growth stagnation uncomfortably high. In a world that is already subject to considerable climate, economic, financial, institutional, political, and social challenges, that is not a scenario we can afford.
