This paper provides new evidence on the existence and magnitude of the “twin deficits” in developing economies. It finds that a one percent of GDP unanticipated increase in the government budget balance improves, on average, the current account balance by 0.8 percentage point of GDP. This effect is substantially larger than that obtained using standard measures of fiscal impulse, such as the cyclically-adjusted budget balance. The results point to heterogeneity across countries and over time. The effect tends to be larger: (i) during recessions; in countries (ii) that are more open to trade; (iii) that have less flexible exchange rate regimes; and (iv) with lower initial public debt-to-GDP ratios.

The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.

This paper examines the relationship between fiscal policy and the current account, drawing on a larger country sample than in previous studies and using panel regressions, vector autoregressions, and an analysis of large fiscal and external adjustments. On average, a strengthening in the fiscal balance by 1 percentage point of GDP is associated with a current account improvement of 0.2–0.3 percentage point of GDP. This association is as strong in emerging and low-income countries as it is in advanced economies; and significantly higher when output is above potential.

This volume brings together nine papers from a conference on international macroeconomics sponsored by the NBER in 1985. International economists as well as graduate students in the fields of global monetary economics, finance, and macroeconomics will find this an outstanding contribution to current research. It includes two commentaries for each paper, written by experts in the field, and Frenkel's detailed introduction, which serves as a reader's guide to the arguments made, the models employed, and the issues raised by each contributor. The studies analyze national fiscal policies within the context of the international economic order. Malcolm D. Knight and Paul R. Masson use an empirical model to show that fiscal changes in recent years in the United States, West Germany, and Japan have caused major disturbances in net savings and investment flows. Linda S. Kole uses a two-country simulation model to examine the effects of a large nation's expansion on exchange rates, interest rates, and the balance of payments. In other studies, Warwick J. McKibbin and Jeffrey D. Sachs discuss the influences of different currency regimes on the international transmission of inflation; Kent P. Kimbrough analyzes the interaction between optimal tax policies and international trade; Sweder van Wijnbergen investigates the interrelation of fiscal policies, trade intervention, and world interest rates; and Willem H. Buiter uses an analytical model to look at fiscal interdependence and optimal policy design. David Backus, Michael Devereux, and Douglas Purvis develop a theoretical model to investigate effects of different fiscal policies in an open economy. Alan C. Stockman looks at the influence of policy anticipation in the private sector, while Lawrence H. Summers shows the effects of differential tax policy on international competitiveness.

We contribute to the intense debate on the real effects of fiscal stimuli by showing that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a novel quarterly dataset of government expenditure in 44 countries, we find that (i) the output effect of an increase in government consumption is larger in industrial than in developing countries, (ii) the fisscal multiplier is relatively large in economies operating under predetermined exchange rate but zero in economies operating under flexible exchange rates; (iii) fiscal multipliers in open economies are lower than in closed economies and (iv) fiscal multipliers in high-debt countries are also zero.

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.

This paper reviews the theoretical and empirical literature on the effectiveness of fiscal policy. The focus is on the size of fiscal multipliers, and on the possibility that multipliers can turn negative (i.e., that fiscal contractions can be expansionary). The paper concludes that fiscal multipliers are overwhelmingly positive but small. However, there is some evidence of negative fiscal multipliers.

This paper focuses on the developing countries, which accounted for nearly half the value of those surpluses, were apparently unable to find sufficiently profitable investments at home that overcame market and political risk. The United States a decade ago likely could not have run up today’s near $800 billion annual deficit for the simple reason that we could not have attracted the foreign savings to finance it. In 1995, for example, total cross-border saving was less than $300 billion. The long-term updrift in this broader swath of unconsolidated deficits and mostly offsetting surpluses of economic entities has been persistent but gradual for decades, probably generations. However, the component of that broad set that captures only the net foreign financing of the imbalances of the individual US economic entities, our current account deficit, increased from negligible in the early 1990s to 6.2 percent of our GDP by 2006.

This paper explores how fiscal policy can affect medium- to long-term growth. It identifies the main channels through which fiscal policy can influence growth and distills practical lessons for policymakers. The particular mix of policy measures, however, will depend on country-specific conditions, capacities, and preferences. The paper draws on the Fund’s extensive technical assistance on fiscal reforms as well as several analytical studies, including a novel approach for country studies, a statistical analysis of growth accelerations following fiscal reforms, and simulations of an endogenous growth model.
