Outlook for global economy in 2019 darkens
Article continues below
Several large emerging markets underwent substantial financial pressures last year.
Against this challenging backdrop, growth in emerging market and developing economies is expected to remain flat in 2019.
The pickup in economies that rely heavily on commodity exports is likely to be much slower than hoped for.
Growth in many other economies is anticipated to decelerate.
Advanced-economy central banks will continue to remove the accommodative policies that supported the protracted recovery from the global financial crisis ten years ago.
Also, simmering trade disputes could escalate.
Higher debt levels have made some economies, particularly poorer countries, more vulnerable to rising global interest rates, shifts in investor sentiment, or exchange rate fluctuations.
In addition, more frequent weather events raise the possibility of large swings in food prices, which could deepen poverty.
Because equitable growth is essential to alleviating poverty and increasing shared prosperity, emerging market and developing economies need to face this challenging economic climate by taking steps to sustain economic momentum, readying themselves for turbulence, and foster long-term growth.
Rebuilding budget and central bank buffers; nurturing human capital; promoting trade integration; and addressing the challenges posed by sometimes large informal sectors, are important ways to do this.
Addressing high levels of debt looms as an increasingly important concern.
In recent years, many low-income countries have gained access to new sources of finance, including private sources and creditors outside the Paris Club of major creditor countries.
This has allowed countries to fund important development needs.
However, it has also contributed to growing public debt.
Government debt levels among low-income countries have risen from debt-to-GDP ratios of 30 percent to 50 percent over the last four years.
Low income countries are using an increasing proportion of government revenues to make interest payments.
Such debt service pressures will only grow further if borrowing costs rise as expected in coming years.
Under these circumstances, were financing conditions to tighten abruptly, countries could experience sudden capital outflows and struggle to refinance debts.
Ideally, public debt should be sustainable and serviced under a wide range of circumstances at reasonable costs.
By increasing the effectiveness of resource mobilization, public spending, as well as strengthening debt management and transparency, low-income countries can reduce the possibility of costly debt stress, support financial sector development, and reduce macroeconomic volatility.
Another avenue toward stronger economic performance may lie in addressing the challenges associated with a large informal sector.
Employment and business outside regulatory, legal and financial structures is widespread in many emerging market and developing economies.
About one-third of GDP in emerging market and developing economies comes from the informal sector, and about 70 percent of employment in these economies is informal.
In some countries in Sub-Saharan Africa, informal employment accounts for more than 90 percent of employment and informal sector produces as much as 62 percent of GDP.
The livelihoods of the poor often depend on informal activity.
The informal sector thrives in certain environments: high prevalence of informality is associated with economic under-development, high levels of taxation and heavy-handed regulation, and corruption and bureaucratic inefficiency.
Yet, while sometimes offering advantages in terms of flexibility and employment, a large informal sector is often associated with lower productivity, reduced tax revenues, and greater poverty and inequality.
Informal firms are one-quarter as productive as companies in the formal sector.
In fact, firms in the formal sector that face informal competition are only three-quarters as productive as those that do not, new World Bank research shows.
Workers in the formal economy earn on average 19 percent more than those in the informal economy.
Countries with the largest informal sectors have government revenues that are 5 to 10 percentage points of GDP lower than those with the lowest levels of informality.
Policymakers can design comprehensive development strategies that, as a collateral benefit, reduce informality.
In addition, they must take care to avoid unintentionally moving workers to the informal sector.
The right policy mix would balance reforms such as improving tax administration, making the labor market more flexible, and strengthening regulatory enforcement with improved provision of pubic goods and services alongside more robust social security systems.
Seeking to shield vulnerable populations from food price spikes may require a shift in policy emphasis away from trade policies.
Authorities have in the past intervened with trade measures to dampen the impact of fluctuations in the prices of key food commodities, including rice, wheat and maize.
But while individual countries can succeed in the short term at buffering domestic markets from price fluctuations, collective action around the world can exacerbate food price volatility and push prices higher – hurting those with the thinnest margins of security.
Policies introduced in 2010-2011 may have accounted for 40 percent of the increase of the world price of wheat and one-quarter of the price rise for maize.
It is estimated that the food price jump of that period pushed 8.3 million people into poverty.
While food prices have declined since peaks at the turn of the decade, world hunger and food insecurity have risen between 2014 and 2017.
The number of undernourished people rose 5 percent to 821 million during that period, and food security challenges have recently been recognized as an urgent priority by the G20.
Further, food price spikes of the kind experienced in 2010-11 could occur again as extreme weather events raise the possibility of disruption to food production.
Instead of interventions such as export bans or the reduction of import duties, effective approaches to soften the blow of higher food prices include better safety nets such as cash and food transfers, school feeding and public works programs.
It is important for countries to have a strategy in place to respond to food crises and to provide adequate resources for these programs.
Even as policymakers and their constituents seek to maintain and accelerate growth in a period of waning momentum, they cannot take for granted a feature that has played an important role in stimulating activity in recent years: a long period of low and stable inflation.
Low and stable inflation is associated with greater output and employment stability, higher growth and better development results.
In contrast, high inflation erodes growth by sapping investor confidence and undermining incentives to save.
Some notable exceptions notwithstanding, emerging market and developing economies have achieved the remarkable feat of lowering inflation from the double digits in the 1970s to about 3.5 percent in 2018.
However, the maintenance of low inflation is not guaranteed, and a number of factors may conspire to push inflation higher in coming years.
A decade after the global financial crisis, many economies are operating at or close to full employment.
The pace of global economic integration could slow or be reversed.
Hard-won central bank independence and transparency could erode in the face of pressures to finance government.
Mounting debt could weaken commitment to strong fiscal and monetary regimes.
If global inflationary pressures rise, policymakers can protect their constituents by redoubling their support for central bank independence, building fiscal frameworks to ensure debt sustainability and maintaining adequate buffers to ride out economic downturns.
As the global economic outlook darkens, the imperative of sustaining economic momentum will require making the most out of growth opportunities, avoiding pitfalls, and building buffers against possible shocks.
Lessons from the past about debt, faith in public institutions, food security, and price stability can offer guidance in an increasingly challenging environment. ■
