Following a strong showing in early 2011, the economies across Europe now face the prospect of a pronounced slowdown, as global growth has softened, risk aversion has risen, and strains in Europe's sovereign debt and financial markets have deepened, according to this issue of the Regional Economic Outlook for Europe. Downside risks are significant, and a further deepening of the euro area crisis would affect not only advanced Europe, but also emerging Europe, given its tight economic and financial ties. The policy stance in advanced Europe will need to be adapted to reflect the weakening and tense outlook, financial systems strengthened further, and a consistent, cohesive and cooperative approach to monetary union adopted by all euro area stakeholders. The cross-country experience in the past decade in Europe shows the difference that good policies can make in boosting growth, with some European countries having grown rapidly while others have stagnated. Escaping low-growth traps, through broad-based reforms that address macroeconomic imbalances and country-specific structural rigidities, is possible.

The September 2011 edition of the World Economic Outlook assesses the prospects for the global economy, which is now in a dangerous new phase. Global activity has weakened and become more uneven, confidence has fallen sharply recently, and downside risks are growing. Against a backdrop of unresolved structural fragilities, a barrage of shocks hit the international economy this year, including the devastating Japanese earthquake and tsunami, unrest in some oil-producing countries, and the major financial turbulence in the euro area. Two of the forces now shaping the global economy are high and rising commodity prices and the need for many economies to address large budget deficits. Chapter 3 examines the inflationary effects of commodity price movements and the appropriate monetary policy response. Chapter 4 explores the implications of efforts by advanced economies to restore fiscal sustainability and by emerging and developing economies to tighten fiscal policy to rebuild fiscal policy room and in some cases to restrain overheating pressures.

Global growth is in low gear, and the drivers of activity are changing. These dynamics raise new policy challenges. Advanced economies are growing again but must continue financial sector repair, pursue fiscal consolidation, and spur job growth. Emerging market economies face the dual challenges of slowing growth and tighter global financial conditions. This issue of the World Economic Outlook examines the potential spillovers from these transitions and the appropriate policy responses. Chapter 3 explores how output comovements are influenced by policy and financial shocks, growth surprises, and other linkages. Chapter 4 assesses why certain emerging market economies were able to avoid the classical boom-and-bust cycle in the face of volatile capital flows during the global financial crisis.

The Arab Spring holds the promise of improved living standards and a more prosperous future for the peoples of the Middle East and North Africa region. At the same time, the region is witnessing uncertainty and economic pressures from domestic and external sources, which will likely be exacerbated by the recent worsening of the global economy. The main challenge in the short term will be to manage expectations while maintaining economic stability. To that end, better-targeted subsidies and transfers will help free up resources for investment in infrastructure, education, and health. Policies aimed at fostering inclusive growth will also help cement the longer-term benefits of the ongoing changes in the region. In the Caucasus and Central Asia, the economic outlook is broadly positive. Exports and remittances--key growth drivers in 2010--are continuing to grow solidly, helping the recovery gain firm momentum. At the same time, uncertainties over the robustness of the global recovery constitute a downside risk to the growth outlook. Key challenges facing the region over the medium term are to create jobs and foster high and inclusive growth.

Despite the recent deterioration in the global economic environment, projections for the region involve only a modest worsening of the outlook. The October 2011 Regional Economic Outlook: Western Hemisphere cautions, however, that there are severe downside risks. A sharp slowdown in Asia, for example in response to a recession in advanced economies, could impact commodity prices, with negative effects on Latin American commodity exporters. With global monetary policy likely to remain accommodative, capital flows could exacerbate overheating and amplify vulnerabilities in emerging markets. Countries with strong real linkages to the United States face a somewhat weaker outlook and should give priority to reducing public debt. Although much of the Caribbean is recovering from a prolonged recession, the outlook remains constrained by high public debt and weak tourism flows. This issue finds that policies can play an important role in mitigating the economic impact of terms-of-trade shocks, and underscores the need to rebuild policy buffers.

The world economy is experiencing a very strong but uneven recovery, with many emerging market and developing economies facing obstacles to vaccination. The global outlook remains uncertain, with major risks around the path of the pandemic and the possibility of financial stress amid large debt loads. Policy makers face a difficult balancing act as they seek to nurture the recovery while safeguarding price stability and fiscal sustainability. A comprehensive set of policies will be required to promote a strong recovery that mitigates inequality and enhances environmental sustainability, ultimately putting economies on a path of green, resilient, and inclusive development. Prominent among the necessary policies are efforts to lower trade costs so that trade can once again become a robust engine of growth. This year marks the 30th anniversary of the Global Economic Prospects. The Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.

In line with the weaker global outlook, growth in Asia is expected to be slightly lower in 2011-12 than forecast in April 2011, mainly as a result of weakening external demand, but the expansion should remain healthy, supported by domestic demand, which has been generally resilient. Overheating pressures remain elevated in a number of economies, with credit growth still robust and inflation momentum generally high, though inflation is expected to recede modestly after peaking in 2011. The sell-off in Asian financial markets in August and September 2011 underscores that an escalation of euro area financial turbulence and a renewed slowdown in the United States could have severe macroeconomic and financial spillovers to Asia. Against this backdrop, Asian low-income and Pacific Island economies face particular challenges in the near and medium term. In low-income countries, the fight against inflation is complicated by strong second-round effects, the need to phase out subsidies, and less well-anchored inflation expectations. Pacific Island economies need to undertake further structural reforms to lift potential growth. The downside risks to growth amid persistent overheating pressures present Asian policymakers with a delicate balancing act, as they need to guard against risks to growth but also limit the adverse impact of prolonged easy financial conditions on inflation and balance sheet vulnerabilities. At the same time, the weakness in global demand only confirms that Asia would greatly benefit from further progress in rebalancing growth by developing domestic sources of demand. In addition to structural reforms, this would require a reprioritization of fiscal spending, in order to create fiscal space for critical infrastructure investment and social priority expenditure.

The European recovery is strengthening and broadening appreciably. Real GDP growth is projected at 2.4 percent in 2017, up from 1.7 percent in 2016, before easing to 2.1 percent in 2018. These are large upward revisions—0.5 and 0.2 percentage point for 2017 and 2018, respectively—relative to the April World Economic Outlook. The European recovery is spilling over to the rest of the world, contributing significantly to global growth. In a few advanced and many emerging economies, unemployment rates have returned to precrisis levels. Most emerging market European economies are now seeing robust wage growth. In many parts of Europe, however, wage growth is sluggish despite falling unemployment.

This year looks set to be another encouraging one for most sub-Saharan African economies. Reflecting mainly strong demand but also elevated commodity prices, the region's economy is set to expand by more than 51⁄4 percent in 2011. For 2012, the IMF staff's baseline projection is for growth to be higher at 53⁄4 percent, owing to one-off boosts to production in a number of countries. There are, however, specters at the feast: the increase in global food and fuel prices, amplified by drought affecting parts of the region, has hit the budgets of the poor and sparked rising inflation, and hesitations in the global recovery threaten to weaken export and growth prospects. The projection for 2012 for the region is highly contingent on global economic growth being sustained at about 4 percent. A further slowing of growth in advanced economies, curtailing global demand, would generate significant headwinds for the region's ongoing expansion, with more globally integrated countries likely to be most affected. Policies in the coming months need to tread a fine line between addressing the challenges that strong growth and recent exogenous shocks have engendered and warding off the adverse effects of another global downturn. In some slower-growing, mostly middle-income countries without binding financial constraints, policies should clearly remain supportive of output growth, even more so if global growth sputters. Provided the global economy experiences the currently predicted slow and steady growth, most of the region's low-income countries should focus squarely on medium-term considerations in setting fiscal policy while tightening monetary policy wherever nonfood inflation has climbed above single digits. In the event of a global downturn, subject to financing constraints, policies in these countries should focus on maintaining planned spending initiatives, while allowing automatic stabilizers to operate on the revenue side. For the region's oil exporters, better terms of trade provide a good opportunity to build up policy buffers against further price volatility.

Major macroeconomic realignments are affecting prospects differentially across the world’s countries and regions. The April 2016 WEO examines the causes and implications of these realignments—including the slowdown and rebalancing in China, a further decline in commodity prices, a related slowdown in investment and trade, and declining capital flows to emerging market and developing economies—which are generating substantial uncertainty and affecting the outlook for the global economy. Additionally, analytical chapters examine the slowdown in capital flows to emerging market economies since their 2010 peak—its main characteristics, how it compares with past slowdowns, the factors that are driving it, and whether exchange rate flexibility has changed the dynamics of the capital inflow cycle—and assess whether product and labor market reforms can improve the economic outlook in advanced economies, looking at the recent evolution and scope for further reform, the channels through which reforms affect economic activity under strong versus weak economic conditions, reforms’ short- to medium-term macroeconomic effects, and sequencing of reforms and coordination with other policies to maximize their potential quantitative economic benefits.
