Heating Up in the South, Cooler in the North broadly describes the economic scene for the Western Hemisphere. The report emphasizes how a mixed environment--with slow recovery in the United States and other advanced economies, but strength in Asia--differently shapes the outlooks for the diverse economies of Latin America and the Caribbean. This issue also focuses on financial issues in Latin America, with a chapter on the challenges of allowing credit to expand safely, without creating excessive risks, and a chapter that looks at macroprudential financial policies--topics especially important in today's context of low global interest rates and capital flows to emerging economies. The final chapter turns to Caribbean economies, exploring the drivers, and obstacles, that affect their growth.

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.

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.

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.

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.

After successfully weathering a series of shocks, most countries in the region are converging to their (tepid) potential. Growth is expected to moderate in late 2024 and 2025 while inflation is projected to continue easing, although gradually. With output and inflation gaps mostly closed but monetary policy still contractionary and public finances in need of strengthening, a further rebalancing of the policy mix is necessary. Fiscal consolidation should advance without delay to rebuild buffers while protecting priority public investment and social spending. This would support the normalization of monetary policy and strengthen credibility and resilience of policy frameworks. Most central banks are well placed to proceed with monetary easing, striking a balance between fending off the risk of reemerging price pressures and avoiding an undue economic contraction. Medium-term growth is expected to remain close to its low historical average, reflecting long-standing, unresolved challenges—including low investment and productivity growth—and shifting demographics. Worrisomely, the ongoing reform agenda is noticeably thin and could lead to a vicious circle of low growth, social discontent, and populist policies. Avoiding this requires pressing on with reforms. Improving governance—by strengthening the rule of law, enhancing government effectiveness, and tackling crime—is a priority that cuts across all areas of growth. Boosting capital accumulation requires improving the business environment, fostering competition, and increasing international trade. Greater and more effective public investment is also needed. Maintaining a dynamic labor force and increasing productivity requires tackling informality and making formal labor markets more flexible, including to adapt to new technologies. Increasing female labor participation can help boost the labor force and offset demographic shifts.

Economies in the Western Hemisphere are generally seeing a slowdown in growth. The U.S. economy regained momentum after a slow start at the beginning of the year, while in Latin America and the Caribbean economic activity continues to decelerate. Stronger U.S. growth should benefit countries in the region, especially those with tighter links through trade, remittances, and tourism (Mexico, Central America, and the Caribbean). Weaker commodity prices for the foreseeable future, however, will continue to hurt South America's net commodity exporters, lowering national incomes, reducing investment, and worsening fiscal balances. These developments could, in turn, impede progress made in recent years in poverty reduction. These developments could, in turn, impede progress made in recent years in poverty reduction. Key risks, including an abrupt tightening of U.S. interest rates or a further slowdown in China, may disproportionately affect Latin America. Chapters in this report examine monetary policy in Latin America, including the region’s exposure to global financial shocks; the role of value chains and regional trade agreements in fostering trade integration; and financial market development in the region.
