Financial Stability and Interest-Rate Policy: A Quantitative Assessment of Costs and Benefits
Description: Should monetary policy use its short-term policy rate to stabilize the growth in household credit and housing prices with the aim of promoting financial stability? We ask this question for the case of Canada. We find that to a first approximation, the answer is no— especially when the economy is slowing down.

Monetary Policy in the Presence of Islamic Banking
Description: This paper discusses key issues related to the conduct of monetary policy in countries that have Islamic banks. It describes the macrofinancial background and monetary policy frameworks where Islamic banks typically operate, and discusses the monetary transmission mechanism in economies where Islamic and conventional banking coexist. Most economies with Islamic banks also have conventional banks and this calls for a comprehensive approach to monetary policy. At the same time, a dual approach to monetary policy should be considered whenever the Islamic segment of the financial system is not as developed as the conventional one. The paper tries to shed light on potential spillovers between conventional and Islamic financial systems, and proposes specific recommendations on the design of Islamic monetary policy operations and for facilitating monetary transmission through the Islamic financial system.

Nowcasting Annual National Accounts with Quarterly Indicators: An Assessment of Widely Used Benchmarking Methods
Description: Benchmarking methods can be used to extrapolate (or “nowcast”) low-frequency benchmarks on the basis of available high-frequency indicators. Quarterly national accounts are a typical example, where a number of monthly and quarterly indicators of economic activity are used to calculate preliminary annual estimates of GDP. Using both simulated and real-life national accounts data, this paper aims at assessing the prediction accuracy of three benchmarking methods widely used in the national accounts compilation: the proportional Denton method, the proportional Cholette-Dagum method with first-order autoregressive error, and the regression-based Chow-Lin method. The results show that the Cholette-Dagum method provides the most accurate extrapolations when the indicator and the annual benchmarks move along the same trend. However, the Denton and Chow-Lin methods could prevail in real-life cases when the quarterly indicator temporarily deviates from the target series.

Implications of Food Subsistence for Monetary Policy and Inflation
Description: We introduce subsistence requirements in food consumption into a simple new-Keynesian model with flexible food and sticky non-food prices. We study how the endogenous structural transformation that results from subsistence affects the dynamics of the economy, the design of monetary policy, and the properties of inflation at different levels of development. A calibrated version of the model encompasses both rich and poor countries and broadly replicates the properties of inflation across the development spectrum, including the dominant role played by changes in the relative price of food in poor countries. We derive a welfare-based loss function for the monetary authority and show that optimal policy calls for complete (in some cases nearcomplete) stabilization of sticky-price non-food inflation, despite the presence of a foodsubsistence threshold. Subsistence amplifies the welfare losses of policy mistakes, however, raising the stakes for monetary policy at earlier stages of development.

Optimal Fiscal Adjustment under Uncertainty
Description: The paper offers a non-probabilistic framework for representation of uncertainty in the context of a simple linear-quadratic model of fiscal adjustment. Instead of treating model disturbances as random variables with known probability distributions, it is only assumed that they belong to some pre-specified compact set. Such an approach is appropriate when the decision maker does not have enough information to form probabilistic beliefs or when considerations for robustness are important. Solution of the model in the minimax sense when disturbance sets are ellipsoids is obtained and the application of the method is illustrated using the example of Portugal.

Tax Administration Reform in China: Achievements, Challenges, and Reform Priorities
Description: Tax administration improvements have contributed significantly to a doubling of China’s tax-to-GDP ratio and the substantial reduction in taxpayers’ compliance costs since the mid-1990s. This paper describes the key features of China’s tax administration and their evolution over the last 20 years. It also identifes emerging challenges to the tax system and areas where further tax administration improvements are needed to sustain tax revenue and reduce taxpayers’ compliance costs in the future.

Foreign Exchange Intervention under Policy Uncertainty
Description: We study the use of foreign exchange (FX) intervention as an additional policy instrument in an environment with learning, where agents infer the central bank policy rules from its policy actions. Under full information, a central bank focused on stabilizing output and inflation can achieve better outcomes by using FX intervention as an additional policy tool. Under policy uncertainty, where agents perceive that monetary policy may also have exchange rate stabilization goals, the use of FX intervention entails a trade-off, reducing output volatility while increasing inflation volatility. While having an additional policy tool is always beneficial, we find that the optimal magnitude of intervention is higher in monetary policy regimes with lower uncertainty. These results indicate that the benefits of using FX intervention as an additional stabilization tool are greater in regimes where monetary policy is credibly focused on output and inflation stabilization.

Serial Sovereign Defaults and Debt Restructurings
Description: Emerging countries that have defaulted on their debt repayment obligations in the past are more likely to default again in the future than are non-defaulters even with the same external debt-to-GDP ratio. These countries actually have repeated defaults or restructurings in short periods. This paper explains these stylized facts within a dynamic stochastic general equilibrium framework by explicitly modeling renegotiations between a defaulting country and its creditors. The quantitative analysis of the model reveals that the equilibrium probability of default for a given debt-to-GDP level is weakly increasing with the number of past defaults. The model also accords with an additional fact: lower recovery rates (high NPV haircuts) are associated with increases in spreads at renegotiation.

Natural Disasters and Food Crises in Low-Income Countries: Macroeconomic Dimensions
Description: The exposure of low-income countries to natural disasters has a significant impact on food production and food security. This paper provides a framework for assessing a country’s vulnerability to food crisis in the event of natural disasters. The paper finds that macroeconomic and structural indicators that are crucial for ensuring the resilience of low-income countries to adverse external shocks are equally important for minimizing the occurrence of food crisis in the event of natural disasters.

China's Slowdown and Global Financial Market Volatility: Is World Growth Losing Out?
Description: China's GDP growth slowdown and a surge in global financial market volatility could both adversely affect an already weak global economic recovery. To quantify the global macroeconomic consequences of these shocks, we employ a GVAR model estimated for 26 countries/regions over the period 1981Q1 to 2013Q1. Our results indicate that (i) a one percent permanent negative GDP shock in China (equivalent to a one-off one percent growth shock) could have significant global macroeconomic repercussions, with world growth reducing by 0.23 percentage points in the short-run; and (ii) a surge in global financial market volatility could translate into a fall in world economic growth of around 0.29 percentage points, but it could also have negative short-run impacts on global equity markets, oil prices and long-term interest rates.
