    Challenges of Fiscal Policy in Emerging and Developing Economies
    (Taylor and Francis, 2018) Huidrom, Raju; Kose, M. Ayhan; Ohnsorge, Franziska L.
    This article presents a systematic analysis of the availability and use of fiscal space in emerging and developing economies. We report two major results. First, emerging and developing economies built fiscal space in the run-up to the Great Recession of 2008–2009, which was then used for stimulus. Since then, fiscal space has shrunk and remains narrow as these economies have taken advantage of historically low interest rates. Second, fiscal policy in emerging and developing economies has become countercyclical (or less procyclical), i.e., “graduated,” since the 1980s, as most clearly demonstrated during the Great Recession. The move towards graduation is most pronounced for those economies with greater fiscal space, which suggests that fiscal space matters for a government’s ability to implement countercyclical fiscal policy.

    Do Fiscal Multipliers Depend on Fiscal Positions?
    (World Bank, Washington, DC, 2016-06) Huidrom, Raju; Kose, M. Ayhan; Lim, Jamus J.; Ohnsorge, Franziska L.
    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) Huidrom, Raju; Kose, M. Ayhan; Ohnsorge, Franziska L.
    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.

    Why Do Fiscal Multipliers Depend on Fiscal Positions?
    (World Bank, Washington, DC, 2019-03) Huidrom, Raju; Kose, M. Ayhan; Lim, Jamus J.; Ohnsorge, Franziska L.
    The fiscal position can affect fiscal multipliers through two channels. Through the Ricardian channel, households reduce consumption in anticipation of future fiscal adjustments when fiscal stimulus is implemented from a weak fiscal position. Through the interest rate channel, fiscal stimulus from a weak fiscal position heightens investors' concerns about sovereign credit risk, raises economy-wide borrowing cost, and reduces private domestic demand. The paper documents empirically the relevance of these two channels using an Interactive Panel Vector Auto Regression model. It finds that fiscal multipliers tend to be smaller when fiscal positions are weak than strong.

    How Important are Spillovers from Major Emerging Markets?
    (World Bank, Washington, DC, 2017-06) Huidrom, Raju; Kose, M. Ayhan; Ohnsorge, Franziska L.
    The seven largest emerging market economies -- China, India, Brazil, Russia, Mexico, Indonesia, and Turkey -- constituted more than one-quarter of global output and more than half of global output growth during 2010-15. These emerging markets, called EM7, are also closely integrated with other countries, especially with other emerging and frontier markets. Given their size and integration, growth in EM7 could have significant cross-border spillovers. The authors provide empirical estimates of these spillovers using a Bayesian vector autoregression model. They report three main results. First, spillovers from EM7 are sizeable: a 1 percentage point increase in EM7 growth is associated with a 0.9 percentage point increase in growth in other emerging and frontier markets and a 0.6 percentage point increase in world growth at the end of three years. Second, sizeable as they are, spillovers from EM7 are still smaller than those from G7 countries (Group of Seven of advanced economies). Specifically, growth in other emerging and frontier markets, and the global economy would increase by one-half to three times more due to a similarly sized increase in G7 growth. Third, among the EM7, spillovers from China are the largest and permeate globally.
