The Coming U.S. Interest Rate Tightening Cycle: Smooth Sailing or Stormy Waters?
(World Bank, Washington, DC, 2015-09-15)Since the global financial crisis, the exceptionally accommodative monetary policy stance of the U.S. Federal Reserve (Fed) has helped support activity, bolstered asset valuations, and reduced risk premia. In addition, it has been instrumental in boosting capital flows to emerging and frontier market economies (EFEs). As the U.S. economy improves, the Fed is expected to start raising policy interest rates in the near term (an event widely referred to as “liftoff”) and thus commence a tightening cycle for the first time in nearly a decade. The mid-2013 “taper tantrum” episode is a painful reminder that even a long-anticipated change in Fed policies can surprise markets in its specifics, and lead to significant financial market volatility and disruptive movements in capital flows to EFEs. Recent debates have focused on the potential impact of the liftoff on EFEs, but there are also significant risks associated with the pace of subsequent rate increases, which is currently expected to be very gradual, but could accelerate at a time when EFE policy buffers are eroding. This Policy Research Note presents a comprehensive analysis of the changes in global conditions since the taper tantrum, risks of disruptions during the upcoming Fed tightening cycle, potential implications for EFEs, and policy options. -

Slowdown in Emerging Markets: Rough Patch or Prolonged Weakness?
(World Bank, Washington, DC, 2015-12)A synchronous growth slowdown has been underway in emerging markets (EM) since 2010. Growth in these countries is now markedly slower than, not just the pre‐crisis average, but also the long‐term average. As a group, EM growth eased from 7.6 percent in 2010 to 4.5 percent in 2014, and is projected to slow further to below 4 percent in 2015. This moderation has affected all regions (except South Asia) and is the most severe in Latin America and the Caribbean. The deceleration is highly synchronous across countries, especially among large EM. By 2015, China, Russia, and South Africa had all experienced three consecutive years of slower growth. The EM‐AE growth differential has narrowed to two percentage points in 2015, well below the 2003‐08 average of 4.8 percentage points and near the long‐term average differential of 1990‐2008. The recent slowdown in EM has been a source of a lively debate, as evident from the quotations at the beginning of this note. Some economists paint a bleak picture for the future of EM and argue that the impressive growth performance of EM prior to the crisis was driven by temporary commodity booms and rapid debt accumulation, and will not be sustained. Others emphasize that a wide range of cyclical and structural factors are driving the slowdown: weakening macroeconomic fundamentals after the crisis; prospective tightening in financial conditions; resurfacing of deep‐rooted governance problems in EM; and difficulty adjusting to disruptive technological changes. Still others highlight differences across EM and claim that some of them are in a better position to weather the slowdown and will likely register strong growth in the future. This policy research note seeks to help move the debate forward by examining the main features, drivers, and implications of the recent EM slowdown and provides a comprehensive analysis of available policy options to counteract it. -

The Great Plunge in Oil Prices: Causes, Consequences, and Policy Responses
(World Bank, Washington, DC, 2015-03)This note combines and distills existing and new research to inform discussion on the topical policy issue of oil prices. Following four years of relative stability at around $105 per barrel (bbl), oil prices have declined sharply since June 2014 and are expected to remain low for a considerable period of time. The drop in prices likely marks the end of the commodity supercycle that began in the early 2000s. Since the past episodes of such sharp declines coincided with substantial fluctuations in activity and inflation, the causes and consequences of and policy responses to the recent plunge in oil prices have led to intensive debates. This paper addresses four questions at the center of these debates, with particular emphasis on emerging market and developing economies: 1) How does the recent decline in oil prices compare with previous episodes? 2) What are the causes of the sharp drop and what is the outlook for oil price? 3) What are the economic and financial consequences? 4) What are the main policy implications? The decline in oil prices will lead to significant real income shifts from oil exporters to oil importers, likely resulting in a net positive effect for global activity over the medium term. However, several factors could counteract the global growth and inflation implications of the lower oil prices. These include weak global demand and limited scope for additional monetary policy easing in many countries. The disinflationary implications of falling oil prices may be muted by sharp adjustments in currencies and effects of taxes, subsidies, and regulations on prices. Regarding fiscal policy, the loss in oil revenues for exporters will strain public finances, while savings among oil importers could help rebuild fiscal space. Lower oil prices also present a window of opportunity to implement structural reforms. These include, in particular, comprehensive and lasting reforms of fuel subsidies, as well as energy taxes more broadly. -

How Does the Sensitivity of Consumption to Income Vary Over Time?: International Evidence
(World Bank, Washington, DC, 2016-04)This paper studies how the sensitivity of consumption to income has changed over time as the degree of financial integration has risen. In standard theory, greater financial integration facilitates international borrowing and lending, helping to reduce the sensitivity of consumption growth to fluctuations in income. The paper examines the empirical validity of this prediction using an array of indicators of financial integration for a large sample of advanced and developing countries over the period 1960-2011. Two main results are reported. First, the sensitivity of consumption to income has declined over time as the degree of financial integration has risen. The decline has been more pronounced in advanced economies than in developing ones. Second, the regression analysis indicates that a higher degree of financial integration is associated with a lower sensitivity of consumption to income. This finding is robust to the use of a wide range of empirical specifications, country-specific characteristics, and other controls, such as interest rates and outcome-based measures of financial integration. The paper also discusses other potential sources of the temporal changes in the sensitivity of consumption to income. -

Do Fiscal Multipliers Depend on Fiscal Positions?
(World Bank, Washington, DC, 2016-06)This paper analyzes the relationship between fiscal multipliers and fiscal positions of governments using an Interactive Panel Vector Auto Regression model and a large data-set of advanced and developing economies. The methodology permits tracing the endogenous relationship between fiscal multipliers and fiscal positions while maintaining enough degrees of freedom to draw sharp inferences. The paper reports three major results. First, the fiscal multipliers depend on fiscal positions: the multipliers tend to be larger when fiscal positions are strong (i.e. when government debt and deficits are low) than weak. For instance, the long-run multiplier can be as large as unity when the fiscal position is strong, while it can be negative when the fiscal position is weak. Second, these effects are separate and distinct from the impact of the business cycle on the fiscal multiplier. Third, the state-dependent effects of the fiscal position on multipliers is attributable to two factors: an interest rate channel through which higher borrowing costs, due to investors' increased perception of credit risks when stimulus is implemented from a weak initial fiscal position, crowd out private investment; and a Ricardian channel through which households reduce consumption in anticipation of future fiscal adjustments. -

Challenges of Fiscal Policy in Emerging and Developing Economies
(World Bank, Washington, DC, 2016-06)This paper presents a systematic analysis of the availability and use of fiscal space in emerging and developing economies. These economies built fiscal space in the run-up to the Great Recession of 2008-09, which was then used for stimulus. This reflects a more general trend over the past three decades, where availability of fiscal space has been associated with increasingly countercyclical (or less procyclical) fiscal policy. However, fiscal space has shrunk since the Great Recession and has not returned to pre-crisis levels. Emerging and developing economies face downside risks to growth and prospects of rising financing costs. In the event that these cause a sharp cyclical slowdown, policy makers may need to employ fiscal policy as a possible tool for stimulus. An important prerequisite for fiscal policy to be effective is that these economies have the necessary fiscal space to employ countercyclical policies. Over the medium-term, credible and well-designed institutional arrangements, such as fiscal rules, stabilization funds, and medium-term expenditure frameworks, can help build fiscal space and strengthen policy outcomes. -

Inflation in Emerging and Developing Economies: Evolution, Drivers and Policies
(Washington, DC: World Bank, 2019)Emerging market and developing economies, like advanced economies, have experienced a remarkable decline in inflation over the past half-century. Yet, research into this development has focused almost exclusively on advanced economies. This book fills that gap, providing the first comprehensive and systematic analysis of inflation in emerging market and developing economies. It examines how inflation has evolved and become synchronized among economies; what drives inflation globally and domestically; where inflation expectations have become better-anchored; and how exchange rate fluctuations can pass through to inflation. To reach its conclusions, the book employs cutting edge empirical approaches. It also offers a rich data set of multiple measures of inflation for a virtually global sample of countries over a half-century to spur further research into this important topic. -

Negative Interest Rate Policies: Sources and Implications
(World Bank, Washington, DC, 2016-08)Against the background of continued growth disappointments, depressed inflation expectations, and declining real equilibrium interest rates, a number of central banks have implemented negative interest rate policies (NIRP) to provide additional monetary policy stimulus over the past few years. This paper studies the sources and implications of NIRP. It reports four main results. First, monetary transmission channels under NIRP are conceptually analogous to those under conventional monetary policy but NIRP present complications that could limit policy effectiveness. Second, since the introduction of NIRP, many of the key financial variables have evolved broadly as implied by the standard transmission channels. Third, NIRP could pose risks to financial stability, particularly if policy rates are substantially below zero or if NIRP are employed for a protracted period of time. Potential adverse consequences include the erosion of profitability of banks and other financial intermediaries, and excessive risk taking. However, there has so far been no significant evidence that financial stability has been compromised because of NIRP. Fourth, spillover implications of NIRP for emerging market and developing economies are mostly similar to those of other unconventional monetary policy measures. In sum, NIRP have a place in a policy maker’s toolkit but, given their domestic and global implications, these policies need to be handled with care to secure their benefits while mitigating risks. -

A Decade After the Global Recession: Lessons and Challenges for Emerging and Developing Economies
(Washington, DC: World Bank, 2021-03-18)This year marks the tenth anniversary of the 2009 global recession. Most emerging market and developing economies weathered the global recession relatively well. However, following a short-lived initial rebound in activity in 2010, the global economy and, especially, emerging market and developing economies, have suffered a decade of weak growth despite unprecedented monetary policy accommodation and several rounds of fiscal stimulus in major economies. A Decade After the Global Recession provides the first comprehensive stock-taking of the decade since the global recession for emerging market and developing economies. It reviews the experience of emerging market and developing economies during and after the recession. Many of these economies have now become more vulnerable to economic shocks. The study discusses lessons from the global recession and policy options for these economies to strengthen growth and be prepared should another global downturn occur. -

Global Waves of Debt: Causes and Consequences
(Washington, DC: World Bank, 2021-03-02)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.
