Lower for Longer: Neutral Rates in the United States
Description: We use a semi structural model to estimate neutral rates in the United States. Our Bayesian estimation incorporates prior information on the output gap and potential output (based on a production function approach) and accounts for unconventional monetary policies at the ZLB by using estimates of “shadow” policy rates. We find that our approach provides more plausible results than standard maximum likelihood estimates for the unobserved variables in the model. Results show a significant trend decline in the neutral real rate over time, driven only in part by a decline in potential growth whereas other factors (including excess global savings) matter. Neutral rates likely turned negative during the Global Financial Crisis and are expected to increase only gradually looking forward.

Avoiding Dark Corners: A Robust Monetary Policy Framework for the United States
Description: The Fed has taken several steps towards strengthening its monetary framework over the past several years. Those steps have supported the Fed’s efforts to stimulate the economy through forward guidance despite being constrained by having policy rates at zero. We show that an optimal control approach to monetary policy, which includes the publication of a baseline forecast and a description of the uncertainties around that outlook, combined with an improvement in the Fed’s communications toolkit, could further enhance the effectiveness of Fed policy. In the current conjuncture, such a risk management approach to monetary policy would result in both a later liftoff of policy rates and a modest, but planned, overshooting of inflation.

Global Food Prices and Domestic Inflation: Some Cross-Country Evidence
Description: This paper provides a broad brush look at the impact of fluctuations in global food prices on domestic inflation in a large group of countries. For advanced economies, we find that these fluctuations have played a significant role over the period from 1960 to the present, but the impact has declined over time and become less persistent. We also find that the more recent global food price shocks occurred in the 2000s had a much bigger impact on emerging than on advanced economies. This larger impact could reflect the larger share of food in the consumption baskets in emerging economies on average than in advanced economies, and less anchored inflation expectations in emerging economies than in advanced economies.

Inflation-Forecast Targeting: Applying the Principle of Transparency
Description: Many central banks in emerging and advanced economies have adopted an inflation-forecast targeting (IFT) approach to monetary policy, in order to successfully establish a stable, low-inflation environment. To support policy making, each has developed a structured system of forecasting and policy analysis appropriate to its needs. A common component is a model-based forecast with an endogenous policy interest rate path. The approach is characterized, among other things, by transparent communications—some IFT central banks go so far as to publish their policy interest rate projection. Some elements of this regime, although a work still in progress, are worthy of consideration by central banks that have not yet officially adopted full-fledged inflation targeting.

The Leap of the Tiger: How Malaysia Can Escape the Middle-Income Trap
Description: Only a few European economies and Korea and Taiwan Province of China reached high-income status during 1970-2010. Malaysia’s real income per capita increased to 26 percent of the U.S. level in 2010 from 20 percent in 1970. Despite relatively strong growth and a substantial improvement in export sophistication, Malaysia’s total factor productivity lagged behind that of Korea and Taiwan Province of China. We argue that what characterizes their experience in contrast to Malaysia’s is the creation of technologies by domestic firms and a push to leapfrog to the technological frontier at an early stage of development.

Unveiling the Effects of Foreign Exchange Intervention: A Panel Approach
Description: We study the effect of foreign exchange intervention on the exchange rate relying on an instrumental-variables panel approach. We find robust evidence that intervention affects the level of the exchange rate in an economically meaningful way. A purchase of foreign currency of 1 percentage point of GDP causes a depreciation of the nominal and real exchange rates in the ranges of [1.7-2.0] percent and [1.4-1.7] percent respectively. The effects are found to be quite persistent. The paper also explores possible asymmetric effects, and whether effectiveness depends on the depth of domestic financial markets.

Monetary Policy in India: Transmission to Bank Interest Rates
Description: This paper provides new evidence on the credit channel of monetary policy transmission in India. Using stepwise estimation of vector error correction models, the analysis finds significant, albeit slow, pass-through of policy rate changes to bank interest rates in India. There is evidence of asymmetric adjustment to monetary policy: the lending rate adjusts more quickly to monetary tightening than to loosening. In addition, the speed of adjustment of deposit and lending rates to changes in the policy rate has increased in recent years.

Gauging Housing Supply in Canada: A Stock Approach
Description: This paper estimates Canada’s housing stock to gauge the supply-side component of the recent exuberance in the Canadian housing sector. The paper adds to the current related literature by focusing on housing units and reconstructing housing stock and households series. An error correction model is estimated at the provincial level over the period 1980-2013 to estimate a measure of housing stock desequilibrium. The model predicts an excess supply in the order of ½ percent above the housing stock level consistent with fundamentals as of 2013.

Push Factors and Capital Flows to Emerging Markets: Why Knowing Your Lender Matters More Than Fundamentals
Description: This paper analyzes the behavior of gross capital inflows across 34 emerging markets (EMs). We first confirm that aggregate inflows to EMs co-move considerably. We then report three findings: (i) the aggregate co-movement conceals significant heterogeneity across asset types as only bank-related and portfolio bond and equity inflows do co-move; (ii) while global push factors in advanced economies mostly explain the common dynamics, their relative importance varies by type of flow; and (iii) the sensitivity to common dynamics varies significantly across borrower countries, with market structure characteristics (especially the composition of the foreign investor base and the level of liquidity) rather than borrower country’s institutional fundamentals strongly affecting sensitivities. Countries relying more on international funds and global banks are found to be more sensitive to push factors. Our findings suggest that EMs need to closely monitor their lenders and investors to assess their inflow exposures to global push factors.

Pension Reforms in Mauritius: Fair and Fast—Balancing Social Protection and Fiscal Sustainability
Description: Despite important past reforms, the ageing population of Mauritius threatens the sustainability of its pension system. This paper examines how pension spending might increase without reforms and discusses reforms options. The findings suggest that unifying the retirement age and indexing it to life expectancy would contribute most significantly to secure and sustainable pensions. The poverty reducing objective of the universal pension can be improved by better targeting. The old age protection objective of the National Pension Fund could be strengthened by increasing contribution and replacement rates. Implementing changes faster should result in less drastic future changes and fairer outcomes.
