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.Abstract. This paper presents a comprehensive examination of the determination and evolution of inflation expectations, with a focus on emerging market and developing economies (EMDEs).

Indeed, in EMDEs, long-term inflation expectations are more sensitive to both domestic and global inflation shocks.

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 2010–2015. These emerging markets, which we call EM7, are also closely integrated with other countries, especially with other emerging and frontier markets (FMs). Given their size and integration, growth in EM7 could have significant cross‐border spillovers. We provide empirical estimates of these spillovers using a Bayesian vector autoregression model. We report three main results. First, spillovers from EM7 are sizeable: a 1 percentage point increase in EM7 growth is associated with an 0.9 percentage point increase in growth in other emerging and FMs and a 0.6 percentage point increase in world growth at the end of 3 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 FMs, 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.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.

This paper quantitatively assesses the effects of inflation shocks on the public debt-to-GDP ratio in 19 advanced economies using simulation and estimation approaches. The simulations suggest that 1 percentage point shock to the inflation rate can reduce the debt-to-GDP ratio by about 0.7 percentage points on average across countries, while the estimated impulse responses are a little larger and more persistent. Additional assumptions taking into account financial repression do not necessarily make these effects substantially larger. These results imply that modestly higher inflation, even if accompanied by some financial repression, could reduce the public debt burden only marginally.
