A number of assumptions have been adopted for the projections presented in the World Economic Outlook. It has been assumed that real effective exchange rates will remain constant at their average levels during January 26–February 23, 2007, except for the currencies participating in the European exchange rate mechanism II (ERM II), which are assumed to remain constant in nominal terms relative to the euro; that established policies of national authorities will be maintained (for specific assumptions about fiscal and monetary policies in industrial countries, see Box A1); that the average price of oil will be $60.75 a barrel in 2007 and $64.75 a barrel in 2008, and remain unchanged in real terms over the medium term; that the six-month London interbank offered rate (LIBOR) on U.S. dollar deposits will average 5.3 percent in 2007 and 5.1 percent in 2008; that the three-month euro deposits rate will average 3.8 percent in 2007 and 3.7 percent in 2008; and that the six-month Japanese yen deposit rate will yield an average of 0.9 percent in 2007 and of 1.2 percent in 2008. These are, of course, working hypotheses rather than forecasts, and the uncertainties surrounding them add to the margin of error that would in any event be involved in the projections. The estimates and projections are based on statistical information available through end-March 2007.

The following conventions have been used throughout the World Economic Outlook:

  • … to indicate that data are not available or not applicable;
  • —to indicate that the figure is zero or negligible;
  • —between years or months (for example, 2005–06 or January–June) to indicate the years or months covered, including the beginning and ending years or months;
  • / between years or months (for example, 2005/06) to indicate a fiscal or financial year.

“Billion” means a thousand million; “trillion” means a thousand billion.

“Basis points” refer to hundredths of 1 percentage point (for example, 25 basis points are equivalent to ¼ of 1 percent point).

In figures and tables, shaded areas indicate IMF staff projections.

Minor discrepancies between sums of constituent figures and totals shown are due to rounding.

As used in this report, the term “country” does not in all cases refer to a territorial entity that is a state as understood by international law and practice. As used here, the term also covers some territorial entities that are not states but for which statistical data are maintained on a separate and independent basis.

The analysis and projections contained in the World Economic Outlook are integral elements of the IMF’s surveillance of economic developments and policies in its member countries, of developments in international financial markets, and of the global economic system. The survey of prospects and policies is the product of a comprehensive interdepartmental review of world economic developments, which draws primarily on information the IMF staff gathers through its consultations with member countries. These consultations are carried out in particular by the IMF’s area departments together with the Policy Development and Review Department, the Monetary and Capital Markets Department, and the Fiscal Affairs Department.

The analysis in this report has been coordinated in the Research Department. The project has been directed by Charles Collyns, Deputy Director of the Research Department, and Tim Callen, Division Chief, Research Department.

The primary contributors to this report are Thomas Helbling, Subir Lall, S. Hossein Samiei, Peter Berezin, Roberto Cardarelli, Kevin Cheng, Florence Jaumotte, Ayhan Kose, Toh Kuan, Michael Kumhof, Douglas Laxton, Valerie Mercer-Blackman, Jonathan Ostry, Alessandro Rebucci, Nikola Spatafora, and Irina Tytell. Olga Akcadag, To-Nhu Dao, Christian de Guzman, Stephanie Denis, Nese Erbil, Angela Espiritu, Patrick Hettinger, Bennett Sutton, and Ercument Tulun provided research assistance. Mahnaz Hemmati, Laurent Meister, and Emory Oakes managed the database and the computer systems. Sylvia Brescia, Celia Burns, and Jemille Colon were responsible for word processing. Other contributors include Anthony Annett, Andrew Benito, Selim Elekdag, Robert Feenstra, Caroline Freund, Jean Imbs, George Kapetanios, Jaewoo Lee, Daniel Leigh, Jaime Marquez, Gian Maria Milesi-Ferretti, Prachi Mishra, Susana Mursula, Christopher Otrok, Cedric Tille, Shang-Jin Wei, and Johannes Wiegand. Archana Kumar of the External Relations Department edited the manuscript and coordinated the production of the publication.

The analysis has benefited from input during the early stages by Raghuram Rajan, the former Economic Counsellor, and from comments and suggestions by staff from other IMF departments, as well as by Executive Directors following their discussion of the report on March 21 and 26, 2007. However, both projections and policy assessments are those of the IMF staff and should not be attributed to Executive Directors or to their national authorities.


The World Economic Outlook team has again done an outstanding job of pulling together both the latest key global macroeconomic developments and the three analytical issues that are highly relevant for accurately reading the current economic environment. The team continues to be ably led by Charles Collyns and Tim Callen and the cornerstone is staff at all levels in the World Economic Studies Division. My predecessor as Economic Counsellor, Raghuram Rajan, contributed key insights during the early stages of preparation. I would also like to stress the importance of inputs both from other parts of the Research Department and—critically—from other departments at the IMF.

It may surprise readers to learn that this World Economic Outlook sees global economic risks as having declined since our last issue in September 2006. Certainly this is at odds with many recent newspaper headlines and commentary, which have focused on problems related to U.S. mortgages, the potential for “disorderly” unwinding of global imbalances, and worries about rising protectionist pressures.

Nevertheless, as discussed in Chapters 1 and 2, looking at the big picture, we actually see the continuation of strong global growth as the most likely scenario. The most immediate concern is bad news from the U.S. housing market, and an associated slowing of U.S. growth. However, these developments have been evident for some months and are largely reflected in market assessments of credit quality. These assessments remain positive for most types of credit. The spreads on lower-quality BBB-rated bonds backed by subprime mortgages have indeed widened substantially, but there has been little change in the yields of lower-rated corporate bonds, let alone those of investment-grade issues. The mainstream mortgage market remains open for business to people with good credit histories.

We should be careful not to underestimate the potential spillovers from the specific problems with high-risk mortgages in the United States but, compared with six months ago and based on the information available today, there is less reason to worry about the global economy. First of all, the overall U.S. economy is holding up well despite the sharp downturn in the housing sector. Investment has slowed somewhat, but consumption remains well supported by a strong labor market and healthy household balance sheets. Unemployment remains low and—in most parts of the U.S. economy—there are good prospects for sustained job growth. Even more important, the signs elsewhere are very encouraging. The euro area is experiencing its fastest growth in six years, Japan’s expansion has momentum, and emerging market and developing countries—led by China and India—continue to enjoy remarkable growth. Overall, taking the five-year period of 2003–07 as a whole, the global economy is achieving its fastest pace of sustained growth since the early 1970s.

These developments, however, do rightly focus our attention on the important issue of spillovers from the United States to the broader global economy. This is the timely focus of Chapter 4, which points out that major global growth slowdowns are generally not due to country-specific developments, even if the country in question is one of the world’s largest economies. Global growth typically declines sharply only when there are events that affect many countries at the same time. The chapter finds that rising trade and financial integration of the global economy does increase the potential impact of spillovers across economies, but even if the U.S. economy were to slow further, the scale of such spillovers should be manageable, especially recognizing the strengthening of macroeconomic policy management around the world over the past 20 years. Flexible exchange rates and forward-looking monetary policies reduce the output effects from all kinds of shocks.

Turning to another risk highlighted in our September 2006 report, there has been definite progress in the right direction with regard to global imbalances. There are encouraging signs that the U.S. current account deficit is now stabilizing, albeit at a high level, helped by a real depreciation of the U.S. dollar and recent strong export performance. Moreover, policy steps have been taken, which, while small, are significant and very real. This movement in the right direction—particularly with regard to actual and intended changes in fiscal policy—is exactly what is needed at this time. However, obviously there is more to be done as the existing configuration of major current accounts is not sustainable indefinitely.

Chapter 3 reassesses the evidence on the role of exchange rates in external adjustment. It confirms that market-led real appreciations and depreciations can support macroeconomic policy changes and private sector saving and investment decisions by facilitating the reallocation of resources across sectors, and help to reduce imbalances without large fluctuations in output. In particular, the chapter pours some cold water on the “exchange rate pessimism” story, in which exchange rates move but do not contribute to current account adjustment. There is also no reason to believe that elasticities or other relevant parameters have declined recently for key countries, such as the United States. If anything, standard models may underestimate how much U.S. trade volumes are likely to respond to changes in relative prices.

Exchange rate adjustment is certainly not a panacea, but it can definitely lower the output costs that would otherwise be involved in changing current account positions. At the same time, we should never lose sight of the need to increase domestic demand in surplus countries, as well as to boost private and government net savings in the United States.

Chapter 5 continues a series of analytical pieces from previous issues of the World Economic Outlook on the process and consequences of the globalization of the world economy, which has been the principal wellspring of recent strong global economic performance. It focuses on the remarkable development of a bigger, more integrated worldwide market for labor. This is one of the central changes of the past 25 years and, in all likelihood, the associated changes will continue to be influential for at least another generation. In part, this global market has developed through the opening up of China, India, and the former communist bloc to the global trading system, as well as through the development of new communications and transportation technologies. But, in equal part, it has been made possible by increasing cross-border movements of financial capital that has sought out attractive skill-wage combinations even in what initially seemed to be unlikely parts of the world.

While there are some legitimate concerns about the pace and composition of those flows, it is important to put them in their proper perspective. This is not a short-run or second-order phenomenon, but rather a major secular shift in where capital finds labor. Put differently, it is the flow of capital and closely associated talent (global management and global ideas) to places where strong complementary skills (including local management and local ideas) are available at attractive prices. This “flow” into emerging markets is really a mutually beneficial set of exchanges that has made possible the creation of a larger global market for labor at low, medium, and high wages. This, in turn, has had great benefits both for the countries using better access to finance to grow faster as well as for everyone who consumes the goods that these countries produce.

The globalization of labor also has had consequences for the distribution of income, and this should not be overlooked. The labor share of income has declined over time in the advanced economies, especially in Europe, and for workers in unskilled sectors. Many factors have contributed, and the findings in Chapter 5 suggest that technological advances rather than globalization of labor is the most important element. The costs of adjustment are not small and, for the people involved, they can be truly traumatic. In fact, it is exactly the loss of jobs in some regions of the United States—due to globalization of labor as well as to technology changes—that has created the most serious reason to worry about parts of the U.S. housing market. If you lose your job, this makes it much harder to service your mortgage, and the increase in distress sales and foreclosures puts downward pressure on house prices. This makes it all the more important, from both a welfare and a macroeconomic perspective, to address the costs of adjustment, including through adequate labor market flexibility, good education and training, and safety nets that cushion but do not obstruct the process of change.

To be clear, the overall risks to global growth remain weighted to the downside, and any slowdown will further complicate people’s lives. But as long as macroeconomic and structural policies are designed and implemented with these risks and real people in mind, a strong global economy should be maintained. And we need to take full advantage of the opportunity that this period provides to push ahead with deep, difficult reforms to ensure both that strong growth can be sustained despite challenges such as population aging and that the benefits of this growth can be shared across all segments of the population.

Notwithstanding the recent bout of financial volatility, the world economy still looks well set for continued robust growth in 2007 and 2008. While the U.S. economy has slowed more than was expected earlier, spillovers have been limited, growth around the world looks well sustained, and inflation risks have moderated. Overall risks to the outlook seem less threatening than six months ago but remain weighted on the downside, with concerns increasing about financial risks.

Global Economic Environment

The global economy expanded vigorously in 2006, growing by 5.4 percent (Chapter 1). In the United States, the expansion slowed in the face of headwinds from a sharp downturn in the housing market, but oil price declines since August have helped to sustain consumer spending. In the euro area, growth accelerated to its fastest pace in six years as domestic demand strengthened. In Japan, activity regained traction toward year-end, after a soft patch in midyear. Among emerging market and developing countries, rapid growth was led by China and India, while momentum was sustained across other regions as countries benefited from high commodity prices and continued supportive financial conditions.

Strong growth and rising oil prices in the first half of 2006 raised concerns about inflation, but pressures have moderated with the decline in oil prices since August. Against the background of strong growth and reduced concerns about inflation, global financial market conditions have generally been buoyant. Despite a bout of financial volatility in February–March 2007, and rising concerns about the U.S. subprime mortgage market, equity markets remain close to all-time highs, real long-term bond yields have remained below long-term trends, and risk spreads have narrowed in most markets.

In foreign exchange markets, the U.S. dollar has weakened, mainly against the euro and pound sterling. The yen has also depreciated further, in part because prospects for continued low interest rates have encouraged capital outflows, although it recovered some ground in early 2007. The Chinese renminbi has declined modestly in real effective terms despite a mild acceleration in its rate of appreciation against the dollar. The U.S. current account deficit rose to 6½ percent of GDP in 2006, although the non-oil trade deficit declined as a percent of GDP as exports accelerated. Surpluses in Japan, China, and the Middle Eastern oil-exporting countries increased further.

The major central banks have faced differing policy challenges in recent months. The U.S. Federal Reserve has kept policy rates on hold since June 2006, seeking to balance risks from a cooling economy and lingering concerns about inflation. The European Central Bank (ECB) and other central banks in Europe have continued to remove monetary accommodation. The Bank of Japan has raised its policy rate very gradually since exiting its zero interest rate policy in July 2006. Some emerging market countries—including China, India, and Turkey—have also tightened monetary policy.

Advanced economies continued to make progress in strengthening their fiscal positions in 2006. Budget deficits were reduced substantially in Germany, Japan, and the United States. Fiscal gains largely reflected strong growth of tax revenues in the cyclical upswing.

Outlook and Risks

Global growth is expected to moderate to 4.9 percent in 2007 and 2008, some ½ percentage point slower than in 2006. In the United States, growth is expected to come down to 2.2 percent this year, from 3.3 percent in 2006, although the economy should gather some momentum during the course of the year as the drag from the housing sector dissipates (Chapter 2). Growth is also expected to ease in the euro area, reflecting in part the gradual withdrawal of monetary accommodation and further fiscal consolidation. In Japan, the expansion is projected to continue at about the same pace as in 2006.

Emerging market and developing countries are expected to continue to grow strongly, albeit at a somewhat slower pace than in 2006. These economies will continue to draw support from benign global financial conditions and commodity prices that remain high notwithstanding recent declines. China’s growth is projected to remain rapid in 2007 and 2008, albeit a little below the torrid pace in 2006, while India’s economy should also continue to grow rapidly. Commodity-rich countries should continue to prosper.

The risks to the growth outlook are less threatening than at the time of the September 2006 World Economic Outlook, but are still tilted to the downside. Particular uncertainties include the potential for a sharper slowdown in the United States if the housing sector continues to deteriorate; the risk of a retrenchment from risky assets if financial market volatility were to rise from historically low levels; the risk that inflation pressures could revive as output gaps continue to close, particularly in the event of another spike in oil prices; and the low probability but high cost risk of a disorderly unwinding of large global imbalances.

A key question in assessing the risks to the outlook is whether the global economy would be able to “decouple” from the United States were the latter to slow down more sharply than projected. To date, the cooling of U.S. activity since early 2006 has had a limited impact abroad beyond its immediate neighbors, Canada and Mexico. As discussed in Chapter 4, this reflects a number of factors, including that the U.S. slowdown has been focused in the housing sector, which has a relatively low import content; that spillovers from the United States are typically more muted in the context of a midcycle slowdown than in a full-blown recession; and that the shock has been a U.S.-specific event rather than a common shock. Nevertheless, were the U.S. economy to slow sharply, this would have a more substantial impact on global growth.

From a longer-term perspective, developments that undermined the buoyant productivity performance of recent years would clearly have an adverse affect on global growth. Strong productivity growth has been supported by a combination of technological progress, an increasingly open global trading system, rising cross-country capital flows, and more resilient macroeconomic policy frameworks and financial systems. It is essential that these pillars remain in place, and that trends that could pose challenges to continued strong global economic performance—such as population aging and global warming—are adequately addressed.

One particular concern is that protectionist forces could undercut trade and foreign investment. If this happens, there is a danger that some of the gains from an increasingly integrated global economy will be reversed. Chapter 5 discusses how the rapid growth of international trade and the introduction of new technologies have fostered an increasingly integrated global labor market that has produced gains in growth and incomes in both source and host countries, while at the same time affecting distributional outcomes. Against this background, more could be done to help those whose jobs may be particularly affected by recent trends in technology and trade, including through better education systems, more flexible labor markets, and welfare systems that cushion the impact of, but do not obstruct, economic change.

Policy Issues

Advanced Economies

The major central banks face varying challenges in managing monetary policy, reflecting differing cyclical positions and degrees of inflation pressure in their economies. In the United States, the Federal Reserve’s approach of holding its rates steady remains appropriate for now, and the path of monetary policy should depend on how incoming data affect the perceived balance of risks between growth and inflation. In the euro area, with growth projected to remain close to or above potential and the possibility of some further upward pressure on factor utilization and prices, raising interest rates further to 4 percent by the summer would seem warranted. In Japan, monetary accommodation should be removed only gradually and on the basis of evidence confirming the continuing strength of the expansion.

Fiscal policy should be directed at achieving the necessary consolidation and reform to maintain viability in the face of aging populations, while providing room for automatic stabilizers to work as needed. Sustained progress toward fiscal consolidation will depend on fundamental reforms to contain increasing outlays as populations age, particularly in areas such as health care and pensions, and to avoid the erosion of revenue bases.

With expansions now firmly established, this is the time to further advance structural reforms aimed at sustaining potential growth. A particular challenge is to ensure that adequate employment opportunities are created within the increasingly global economy and that the less well-off share more in the prosperity created by rising trade and the introduction of new technologies. Some progress has been made in implementing productivity-enhancing reforms in the euro area and Japan, but more needs to be done, particularly in the services and financial sectors. There is also scope to improve the flexibility of the U.S. economy, including by reducing the close link between health care coverage and employment to increase labor mobility.

Emerging Market and Developing Economies

Many emerging market and developing countries face the challenge of maintaining stable macroeconomic and financial conditions in the face of strong foreign exchange inflows. Exchange rates in several Asian countries have appreciated markedly over the past six months, but China would benefit from a more flexible regime that provides a more secure basis for monetary policy management. In emerging Europe, policies need to minimize risks associated with large current account deficits and rapid credit growth. In Latin America, the task is to consolidate recent progress toward strengthening public sector balance sheets. In commodity-exporting countries, the rapid rise in export receipts and government revenues needs to continue to be carefully managed to avoid overheating.

Recent progress on structural reforms has generally been patchy and the “to do” list remains long. Further progress in liberalizing service sectors in Asia and elsewhere would help sustain and extend productivity improvements. Accelerating labor market reforms in Latin America would help boost the region’s poor productivity performance. Establishing stable, transparent, and balanced regimes for infrastructure provision and for the exploitation of natural resources would help to reduce risks of bottlenecks, corruption, and lack of investment that could prove to be serious impediments to long-term growth.

Multilateral Initiatives and Policies

Cooperative policy actions are necessary to support the smooth unwinding of large global imbalances. Important elements of such an approach—which are being discussed in the context of the IMF’s Multilateral Consultations—include efforts to raise saving in the United States, including through more ambitious fiscal consolidation and steps to reduce disincentives to private savings; advancing growth-enhancing reforms in the euro area and Japan; and measures to boost consumption and increase upward exchange rate flexibility in some parts of emerging Asia, especially China. Among Middle Eastern oil exporters, lower oil prices and increased spending are expected to reduce external surpluses, although there is still scope to continue to boost spending, subject to absorptive capacity constraints.

As emphasized in Chapter 3, market-led movements in real effective exchange rates could potentially play an important supportive role in the adjustment of global imbalances. Currency depreciation could help to contain the output costs that may accompany the demand rebalancing needed to lower current account deficits by encouraging a smooth shift in resources across sectors. Encouragingly, the chapter finds that concerns about “elasticity pessimism”—that U.S. trade flows are unresponsive to real exchange rate changes—are exaggerated, consistent with the view that a real effective depreciation of the dollar over the medium term could contribute to reducing the U.S. current account deficit. To be most effective, the counterpart to this realignment of the U.S. dollar would be real exchange rate appreciations in countries with persistent current account surpluses, including China, Japan, and Middle Eastern oil exporters.

The recent revival in the Doha Round of multilateral trade negotiations is welcome. Reaching a Doha Round conclusion that achieves ambitious multilateral trade reform and further strengthens multilateral rules so as to reduce the risks of protectionism would provide an important boost to the global outlook. Prospects for a sustained global expansion and a gradual unwinding of global imbalances would also benefit from initiatives to remove obstacles to the smooth reallocation of resources in response to exchange rate movements, including through trade reform.
