The uncertain costs of MENA’s dual shock

780
Countries in the Middle East and North Africa are facing both the Covid-19 pandemic and a collapse in oil prices. Given the unprecedentedly fast-evolving global health crisis and highly volatile oil price, estimating the costs of the dual shock and forecasting economy is challenging. But as this column explains, changes in forecasts can provide some information on the costs of the crises.

In a nutshell

The costs of the crisis are a moving target: global, policy and social responses are fluid.

As time goes by, the main driver of expected costs is the health system with transparency at a premium.

National policy responses should follow a ‘sequencing without delay’ approach with transparency at a premium.

Research from the International Monetary Fund (IMF) shows that economists generally have difficulties forecasting severe economic downturns (IMF, 2018). Similarly, World Bank research finds that rare and large negative shocks – so-called ‘black swan’ events – are even harder to predict than run-of-the-mill recessions. Thus, predicting the costs of the current dual shock is difficult (World Bank, 2018).

Nevertheless, close inspection of the changes in the World Bank’s growth forecasts (Figure 1) can shed light on the beliefs of the institution’s economists about the nature of the impact of the dual shock on growth expectations for the Middle East and North Africa (MENA) in 2020-21.

Figure 1: Fluid estimates of the costs of the crisis – changes in World Bank growth forecasts

Panel A shows the changes in the growth forecasts between those conducted in 1 April 2020 and those published in October 2019, for MENA as a whole, the countries of the Gulf Cooperation Council (GCC), developing oil exporters and developing oil importers. The sharpest drop in 2020 growth forecasts corresponds to the developing oil exporters, followed by the developing oil importers and then by the GCC countries.

Panel B illustrates how forecasts can be fluid and subject to change when new data become available. Between 19 March and 1 April 2020, World Bank economists sharply increased their estimates of the cost of the dual shock, and downgraded growth rates in 2020 and 2021 for MENA.

To the extent that the full repercussions of the dual shock have not been fully captured in economic forecasts, it is safe to conclude that our estimates of the costs of the crisis are conservative; they can be interpreted as lower bound estimates of the costs.

Uncertainty also dominated private sector forecasts for the MENA region between December and March (see Table 1). The variance across forecasts as of March is orders of magnitude larger than the magnitude of the growth downgrades (relative to December). Furthermore, the magnitude of the growth downgrades is correlated with the variance of the forecasts.

A closer look at the World Bank forecast adjustments suggests that the changes in the forecasts are systematically related to initial pre-existing conditions, particularly each economy’s health system (see Figure 2). But oil export exposure had a significant effect only in the March forecast, with little influence in the April adjustment.

To net out the effects of pre-existing conditions and cyclicality, we decompose the change in economic expectations as follows: C = V + P + O – CYC. Where C is the change between ex post and ex ante expectations; V is change due to the spread of the virus; P is change due to the collapse of oil prices; O is other pre-existing conditions; and CYC is change due to cyclical factors.

While Figure 2 illustrates effects from the first two elements – namely Covid-19 and oil price-related changes – Lebanon provides a good example of the role of pre-existing conditions. Downgrades in not only the forecasted growth rate in 2020 but also in growth rates estimated for 2019 suggests that prior to Lebanon’s exposure to Covid-19 and the oil price collapse, the country was already facing crises, such as the larger than expected and still increasing fiscal deficit.

To deal with the dual shock, a two-pronged approach can be pursued. One is immediate and related to the health emergency. The other concerns forward-looking policy reforms. Authorities could sequence and tailor their responses to the severity of the shock. That is, it might be desirable to focus first on responding to the health emergency and the associated economic contraction.

Fiscal consolidation and structural reforms associated with the persistent drop in oil prices and pre-existing challenges are also very important, but with proper external support, they can wait until the health emergency subsides. After the crisis, budget-neutral reforms such as debt transparency and reforms of state-owned enterprises will also come to the fore.

In summary, the costs of the crisis are a moving target: global, policy and social responses are fluid. As time goes by, the main driver of expected costs is the health system with transparency at a premium. National responses should follow a ‘sequencing without delay’ approach.

Trust in Lebanon’s public institutions: a challenge for the new leadership

Lebanon’s new leadership confronts daunting economic challenges amid geopolitical tensions across the wider region. As this column explains, understanding what has happened over the past decade to citizens’ trust in key public institutions – parliament, the government and the armed forces – will be a crucial part of the policy response.

Qatarisation: playing the long game on workforce nationalisation

As national populations across the Gulf have grown and hydrocarbon reserves declined, most Gulf countries have sought to move to a more sustainable economic model underpinned by raising the share of citizens in the productive private sector. But, as this column explains, Qatar differs from its neighbours in several important ways that could render aggressive workforce nationalization policies counterproductive. In terms of such policies, the country should chart its own path.

Small businesses in the Great Lockdown: lessons for crisis management

Understanding big economic shocks like Covid-19 and how firms respond to them is crucial for mitigating their negative effects and accelerating the post-crisis recovery. This column reports evidence on how small and medium-sized enterprises in Tunisia’s formal business sector adapted to the pandemic and the lockdown – and draws policy lessons for when the next crisis hits.

Economic consequences of the 2003 Bam earthquake in Iran

Over the decades, Iran has faced numerous devastating natural disasters, including the deadly 2003 Bam earthquake. This column reports evidence on the unexpected economic boost in Bam County and its neighbours after the disaster – the result of a variety of factors, including national and international aid, political mobilisation and the region’s cultural significance. Using data on the intensity of night-time lights in a geographical area, the research reveals how disaster recovery may lead to a surprising economic rebound.

The impact of climate change and resource scarcity on conflict in MENA

The interrelationships between climate change, food production, economic instability and violent conflict have become increasingly relevant in recent decades, with climate-induced economic shocks intensifying social and political tensions, particularly in resource-constrained regions like MENA. This column reports new evidence on the impact of climate change on economic and food production outcomes – and how economic stability, agricultural productivity and shared water resources affect conflict. While international aid, economic growth and food security reduce the likelihood of conflict, resource scarcity and shared water basins contribute to high risks of conflict.

Qatar’s pursuit of government excellence: promises and pitfalls

As Qatar seeks to make the transition from a hydrocarbon-based economy to a diversified, knowledge-based economy, ‘government excellence’ has been identified as a key strategic objective. This column reports what government effectiveness means in terms of delivery of public services, digitalisation of services, and control of corruption – and outlines the progress made to date on these development priorities and what the country needs to do to meet its targets.

A Macroeconomic Accounting of Unemployment in Jordan:  Unemployment is mainly an issue for adults and men

Since unemployment rates in Jordan are higher among young people and women than other groups, unemployment is commonly characterised as a youth and gender issue. However, the majority of the country’s unemployed are adults and men. This suggests that unemployment is primarily a macroeconomic issue challenge for the entire labour market. The appropriate response therefore is coordinated fiscal, monetary, structural and institutional policies, while more targeted measures can still benefit specific groups.

The green energy transition: employment pathways for MENA

The potential employment impacts of green and renewable energy in the Middle East and North Africa are multifaceted and promising. As this column explains, embracing renewable energy technologies presents an opportunity for the region to diversify its economy, mitigate the possible negative impacts of digitalisation on existing jobs, reduce its carbon footprint and create significant levels of employment across a variety of sectors. Green energy is not just an environmental imperative but an economic necessity.

Tunisia’s energy transition: the key role of small businesses

Micro, small and medium-sized enterprises (MSMEs) play a critical role in Tunisia’s economy, contributing significantly to GDP and employment. As this column explains, they are also essential for advancing the country’s ambitions to make a successful transition from reliance on fossil fuels to more widespread use of renewable energy sources. A fair distribution of the transition’s benefits across all regions and communities will secure a future where MSMEs thrive as leaders in a prosperous, inclusive and sustainable Tunisia.

Global value chains, wages and skills in MENA countries

The involvement of firms in production across different countries or regions via global value chains (GVCs) can make a significant contribution to economic development, including improved labour market outcomes. This column highlights the gains from GVC participation in terms of employment quality in Egypt, Jordan and Tunisia. Given the high unemployment, sticky wages and wide skill divides that are common in the MENA region, encouraging firms to participate in GVCs is a valuable channel for raising living standards.
