Global growth for 2018–19 is projected to remain steady at its 2017 level, but its pace is less vigorous than projected in April and it has become less balanced. Downside risks to global growth have risen in the past six months and the potential for upside surprises has receded. Global growth is projected at 3.7 percent for 2018–19—0.2 percentage point lower for both years than forecast in April. The downward revision reflects surprises that suppressed activity in early 2018 in some major advanced economies, the negative effects of the trade measures implemented or approved between April and mid-September, as well as a weaker outlook for some key emerging market and developing economies arising from country-specific factors, tighter financial conditions, geopolitical tensions, and higher oil import bills. The balance of risks to the global growth forecast has shifted to the downside in a context of elevated policy uncertainty. Several of the downside risks highlighted in the April 2018 World Economic Outlook (WEO)—such as rising trade barriers and a reversal of capital flows to emerging market economies with weaker fundamentals and higher political risk—have become more pronounced or have partially materialized. Meanwhile, the potential for upside surprises has receded, given the tightening of financial conditions in some parts of the world, higher trade costs, slow implementation of reforms recommended in the past, and waning growth momentum.

Global economic activity is picking up with a long-awaited cyclical recovery in investment, manufacturing, and trade, according to Chapter 1 of this World Economic Outlook. World growth is expected to rise from 3.1 percent in 2016 to 3.5 percent in 2017 and 3.6 percent in 2018. Stronger activity, expectations of more robust global demand, reduced deflationary pressures, and optimistic financial markets are all upside developments. But structural impediments to a stronger recovery and a balance of risks that remains tilted to the downside, especially over the medium term, remain important challenges. Chapter 2 examines how changes in external conditions may affect the pace of income convergence between advanced and emerging market and developing economies. Chapter 3 looks at the declining share of income that goes to labor, including the root causes and how the trend affects inequality. Overall, this report stresses the need for credible strategies in advanced economies and in those whose markets are emerging and developing to tackle a number of common challenges in an integrated global economy.

Global growth remains moderate and uneven, and a number of complex forces are shaping the outlook. These include medium- and long-term trends, global shocks, and many country- or region-specific factors. The April 2015 WEO examines the causes and implications of recent trends, including lower oil prices, which are providing a boost to growth globally and in many oil-importing countries but are weighing on activity in oil-exporting countries, and substantial changes in exchange rates for major currencies, reflecting variations in country growth rates and in exchange rate policies and the lower price of oil. Additionally, analytical chapters explore the growth rate of potential output across advanced and emerging market economies, assessing its recent track and likely future course; and the performance of private fixed investment in advanced economies, which has featured prominently in the public policy debate in recent years, focusing on the role of overall economic weakness in accounting for this performance.

This issue discusses a number of factors affecting global growth, as well as growth prospects across the world's main countries and regions. It assesses the ongoing recovery from the global financial crisis in advanced and emerging market economies and evaluates risks, both upside and downside, including those associated with commodity prices, currency fluctuations, and financial market volatility. A special feature examines in detail causes and implications of the recent commodity price downturn; analytical chapters look at the effects of commodity windfalls on potential output and of exchange rate movements on trade.

The countries in the Caucasus and Central Asia (CCA) have recorded significant macroeconomic achievements since independence. These countries have grown more rapidly-—on average by 7 percent over 1996–2011—-than those in many other regions of the world and poverty has declined. Inflation has come down sharply from high rates in the 1990s and interest rates have fallen. Financial sectors have deepened somewhat, as evidenced by higher deposits and lending. Fiscal policies were broadly successful in building buffers prior to the global crisis and those buffers were used effectively by many CCA countries to support growth and protect the most vulnerable as the crisis washed across the region. CCA oil and gas exporters have achieved significant improvements in living standards with the use of their energy wealth.

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 October 2012 World Economic Outlook (WEO) assesses the prospects for the global recovery in light of such risks as the ongoing euro area crisis and the “fiscal cliff” facing U.S. policymakers. Reducing the risks to the medium-term outlook implies reducing public debt in the major advanced economies, and Chapter 3 explores 100 years of history of dealing with public debt overhangs. In emerging market and developing economies, activity has been slowed by policy tightening in response to capacity constraints, weaker demand from advanced economies, and country-specific factors, but policy improvements have raised these economies'resilience to shocks, an issue explored in depth in Chapter 4.

The World Economic Outlook (WEO) presents the IMF's leading economists'analyses of global economic developments during the near and medium terms. It is a respected, one-stop, trusted resource offering remarkable insight, balance, and perspective to decision makers and policymakers worldwide. Published twice yearly, the World Economic Outlook presents the outlook for growth, inflation, trade, employment, and other economic developments in a clear, practical format. Each WEO considers the issues affecting advanced, emerging market, and developing economies. Central bankers, economists, Financial institutions, business leaders, governments, think tanks, and researchers eagerly await this unique investigation of what's happening and what's ahead.

The global economic recovery is progressing better than expected, but the speed of recovery varies, as outlined in the April 2010 World Economic Outlook. Some countries, notably in Asia, are off to a strong start, but growth in others is constrained by lasting damage to the financial sector and to household balance sheets. The challenge for policymakers is to ensure a smooth transition of demand, while maintaining supports that promote growth and employment. There is also a need to contain and reduce public debt and repair and reform the financial sector. This issue of the WEO also explores two other key challenges in the wake of the Great Recession: how to spur job creation in the face of likely high and persistent unemployment in advanced economies, and how countries that previously ran large current account surpluses or deficits can promote growth by rebalancing external and domestic demand.

This edition of the World Economic Outlook explores how a dramatic escalation of the financial crisis in September 2008 provoked an unprecedented contraction of activity and trade, despite active policy responses. It presents economic projections for 2009 and 2010, and also looks beyond the current crisis, considering factors that will shape the landscape of the global economy over the medium term, as businesses and households seek to repair the damage. The analysis also outlines the difficult policy challenges presented by the overwhelming imperative to take all steps necessary to restore financial stability and revive the global economy, and the longer-run need for national actions to be mutually supporting. The first of two analytical chapters,'What Kind of Economic Recovery?'explores the shape of the eventual recovery. The second,'The Transmission of Financial Stress from Advanced to Emerging and Developing Economies,'focuses on the role of external financial linkages and financial stress in transmitting economic shocks.
