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. -

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. -

Inflation Expectations: Review and Evidence
(World Bank, Washington, DC, 2019-03)This paper presents a comprehensive examination of the determination and evolution of inflation expectations, with a focus on emerging market and developing economies (EMDEs). The results suggest that long-term inflation expectations in EMDEs are not as well anchored as those in advanced economies, despite notable improvements over the past two decades. Indeed, in EMDEs, long-term inflation expectations are more sensitive to both domestic and global inflation shocks. However, EMDEs tend to be more successful in anchoring inflation expectations in the presence of an inflation targeting regime, high central bank transparency, strong trade integration, and a low level of public debt. -

Understanding Inflation in Emerging and Developing Economies
(World Bank, Washington, DC, 2019-02)Emerging market and developing economies (EMDEs) have experienced an extraordinary decline in inflation since the early 1970s. After peaking in 1974 at 17.3 percent, inflation in these economies declined to 3.5 percent in 2017. Despite a checkered history of managing inflation among many EMDEs, disinflation occurred across all regions. This paper presents a summary of a recent book, "Inflation in Emerging and Developing Economies: Evolution, Drivers, and Policies," that analyzes this remarkable achievement. The findings suggest that many EMDEs enjoy the benefits of stability-oriented and resilient monetary policy frameworks, including central bank transparency and independence. Such policy frameworks need to be complemented by strong macroeconomic and institutional arrangements. Inflation expectations are more weakly anchored in EMDEs than in advanced economies. In EMDEs that do not operate inflation targeting frameworks, exchange rate movements tend to have larger and more persistent effects on inflation. -

Debt and Financial Crises
(World Bank, Washington, DC, 2020-01)Emerging market and developing economies have experienced recurrent episodes of rapid debt accumulation over the past fifty years. This paper examines the consequences of debt accumulation using a three-pronged approach: an event study of debt accumulation episodes in 100 emerging market and developing economies since 1970; a series of econometric models examining the linkages between debt and the probability of financial crises; and a set of case studies of rapid debt buildup that ended in crises. The paper reports four main results. First, episodes of debt accumulation are common, with more than 500 episodes occurring since 1970. Second, around half of these episodes were associated with financial crises which typically had worse economic outcomes than those without crises -- after 8 years output per capita was typically 6-10 percent lower and investment 15-22 percent weaker in crisis episodes. Third, a rapid buildup of debt, whether public or private, increased the likelihood of a financial crisis, as did a larger share of short-term external debt, higher debt service cover, and lower reserves cover. Fourth, countries that experienced financial crises frequently employed combinations of unsustainable fiscal, monetary and financial sector policies, and often suffered from structural and institutional weaknesses. -

Can This Time Be Different? Policy Options in Times of Rising Debt
(World Bank, Washington, DC, 2020-03)Episodes of debt accumulation have been a recurrent feature of the global economy over the past fifty years. Since 2010, emerging and developing economies have experienced another wave of historically large and rapid debt accumulation. Similar past debt buildups have often ended in widespread financial crises in these economies. This paper examines the factors that are likely to determine the outcome of the most recent debt wave, and considers policy options to help reduce the likelihood that it ends again in widespread crises. It reports two main results. First, the rapid increase in debt has made emerging and developing economies more vulnerable to shifts in market sentiment, notwithstanding historically low global interest rates. Second, policy options are available to lower the likelihood of financial crises, and to help manage the adverse impacts of crises when they do occur. These include sound debt management, strong monetary and fiscal frameworks, and robust bank supervision and regulation. The post-crisis debt buildup has coincided with a period of subdued growth as well as the emergence of non-traditional creditors. As a result, policy priorities also need to ensure that debt is spent on productive purposes to improve growth prospects and that all debt-related transactions are transparently reported.
