Despite setbacks, an uneven global recovery continues. Largely due to weaker-than-expected global activity in the first half of 2014, the growth forecast for the world economy has been revised downward to 3.3 percent for this year, 0.4 percentage point lower than in the April 2014 World Economic Outlook (WEO). The global growth projection for 2015 was lowered to 3.8 percent.
Downside risks have increased since the spring. Shortterm risks include a worsening of geopolitical tensions and a reversal of recent risk spread and volatility compression in financial markets. Medium-term risks include stagnation and low potential growth in advanced economies and a decline in potential growth in emerging markets.
Given these increased risks, raising actual and potential growth must remain a priority. In advanced economies, this will require continued support from monetary policy and fiscal adjustment attuned in pace and composition to supporting both the recovery and longterm growth. In a number of economies, an increase in public infrastructure investment can also provide support to demand in the short term and help boost potential output in the medium term. In emerging markets, the scope for macroeconomic policies to support growth if needed varies across countries and regions, but space is limited in countries with external vulnerabilities. And in advanced economies as well as emerging market and developing economies, there is a general, urgent need for structural reforms to strengthen growth potential or make growth more sustainable.
After a slowdown in the first half of 2014, global growth is forecast to strengthen to 3.5 percent in the second half of 2014 and 3.8 percent in 2015. But growth is uneven and still weak overall and remains susceptible to many downside risks. Production disruptions or sharply higher global oil prices—due to geopolitical tensions—would reduce global growth, as would an unexpected tightening in financial conditions owing to higher-than-expected U.S. long-term interest rates or increased risk aversion. Over the medium term, protracted weak demand in advanced economies could result in lower growth everywhere, including, in part, through negative supply-side effects.
This chapter finds that increased public infrastructure investment raises output in both the short and long term, particularly during periods of economic slack and when investment efficiency is high. This suggests that in countries with infrastructure needs, the time is right for an infrastructure push: borrowing costs are low and demand is weak in advanced economies, and there are infrastructure bottlenecks in many emerging market and developing economies. Debt-financed projects could have large output effects without increasing the debt-to-GDP ratio, if clearly identified infrastructure needs are met through efficient investment.

Chapter 4: Are Global Imbalances at a Turning Point?
Global current account ("flow") imbalances have narrowed significantly since their peak in 2006, and their configuration has changed markedly in the process. The imbalances that used to be the main concern—the large deficit in the United States and surpluses in China and Japan—have more than halved. But some surpluses, especially those in some European economies and oil exporters, remain large, and those in some advanced commodity exporters and major emerging market economies have since moved to deficit. This chapter argues that the reduction of large flow imbalances has diminished systemic risks to the global economy. Nevertheless, two concerns remain.
