What is Responsible for India’s Sharp Disinflation?
Description: We analyze the dramatic decline in India’s inflation over the last two years using an augmented Phillips Curve approach and quantify the role of different factors. Our results suggest that, contrary to popular perception, the direct role of lower oil prices in India’s disinflation was relatively modest given the limited pass-through into domestic prices. Instead, we find that inflation is a highly persistent process in India, reflecting very adaptive expectations and the backward looking nature of wage and support price-setting. As a consequence, we find that a moderation of expectations, both backward and forward, and a rationalization of Minimum Support Prices (MSPs), explain the bulk of the disinflation over the last two years.

Evolution of Exchange Rate Behavior in the ASEAN-5 Countries
Description: This paper examines exchange rate behavior in the ASEAN-5 countries (Indonesia, Malaysia, the Philippines, Singapore, and Thailand). It finds that for the last 10 years there is no evidence that their central banks target particular exchange rate levels against any currency or basket. Thus, contrary to some assertions, they do not belong to a U.S. dollar club, a Japanese yen club, a Chinese renminbi club, or an ASEAN club. At the same time, they clearly try to smooth short-term volatility, particularly vis-à-vis the U.S. dollar. The degree of smoothing declined noticeably after the Asian Financial Crisis and less obviously after the Global Financial Crisis, with heterogeneity across countries. Short-term smoothing without level targeting does not interfere with monetary policies aimed at price stability.

Investing to Mitigate and Adapt to Climate Change: A Framework Model
Description: We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused development remains an open question. The paper places particular emphasis on the changing level of risk and vulnerabilities faced by developing countries as they allocate investment toward growth strategies, adapting to climate change and emissions mitigation.

A Probabilistic Approach to Fiscal Space and Prudent Debt Level: Application to Low-Income Developing Countries
Description: What constitutes fiscal space or a prudent level of debt to conduct countercyclical policy while ensuring debt sustainability? This paper addresses the question by exploring the relationship between debt dynamics, and the probabilistic distribution of the primary balance and the effective interest rate. This proposed approach is useful in situations where the lack of relevant data makes it difficult to estimate detailed fiscal reaction functions. Applying this approach to Low-Income Developing Countries (LIDCs) and based on various debt ceiling assumptions, we find that about 60 percent of these countries presently have fiscal policy space to address adverse shocks, subject to the availability of domestic and external financing. Countries with strong institutional capacity tend to have more fiscal space, and countries with weak institutional capacity, mostly countries in conflict and fragile states, tend to lack fiscal space.

From Firm-Level Imports to Aggregate Productivity: Evidence from Korean Manufacturing Firms Data
Description: Using the Korean manufacturing firm-level data, this paper confirms that three stylized facts on importing hold in Korea: the ratio of imported inputs in total inputs tends to be procyclical; the use of imported inputs increases productivity; and larger firms are more likely to use imported inputs. As a result, we find that firm-level import decisions explain a non-trivial fraction of aggregate productivity fluctuations in Korea over the period between 2006 and 2012. Main findings of this paper suggest a possible link between the recent global productivity slowdown and the global trade slowdown.

The Impact of Oil Prices on the Banking System in the GCC
Description: This paper examines the links between global oil price movements and macroeconomic and financial developments in the GCC. Using a range of multivariate panel approaches, including a panel vector autoregression approach, it finds strong empirical evidence of feedback loops between oil price movements, bank balance sheets, and asset prices. Empirical evidence also suggests that bank capital and provisioning have behaved countercyclically through the cycle.

Testing Piketty’s Hypothesis on the Drivers of Income Inequality: Evidence from Panel VARs with Heterogeneous Dynamics
Description: Thomas Piketty's Capital in the Twenty-First Century puts forth a logically consistent explanation for changes in income and wealth inequality patterns. However, while rich in data, the book provides no formal empirical testing for its theoretical causal chain. In this paper, I build a set of Panel SVAR models to check if inequality and capital share in the national income move up as the r-g gap grows. Using a sample of 19 advanced economies spanning over 30 years, I find no empirical evidence that dynamics move in the way Piketty suggests. Results are robust to several alternative estimates of r-g.

Inflation and the Black Market Exchange Rate in a Repressed Market: A Model of Venezuela
Description: This paper presents a stylized general equilibrium model of the Venezuelan economy. The model explains how the recent sharp fall in oil revenue combines with foreign exchange rationing to produce a steep rise in inflation. Counterintuitively, a devaluation of the official exchange rate could temporarily reduce inflation. The model also explains how the hyper-depreciation of the black market exchange rate reflects prices in the most distorted goods markets.

Measuring Concentration Risk - A Partial Portfolio Approach
Description: Concentration risk is an important feature of many banking sectors, especially in emerging and small economies. Under the Basel Framework, Pillar 1 capital requirements for credit risk do not cover concentration risk, and those calculated under the Internal Ratings Based (IRB) approach explicitly exclude it. Banks are expected to compensate for this by autonomously estimating and setting aside appropriate capital buffers, which supervisors are required to assess and possibly challenge within the Pillar 2 process. Inadequate reflection of this risk can lead to insufficient capital levels even when the capital ratios seem high. We propose a flexible technique, based on a combination of “full” credit portfolio modeling and asymptotic results, to calculate capital requirements for name and sector concentration risk in banks’ portfolios. The proposed approach lends itself to be used in bilateral surveillance, as a potential area for technical assistance on banking supervision, and as a policy tool to gauge the degree of concentration risk in different banking systems.

The Case for an Independent Fiscal Institution in Japan
Description: In response to the recent financial crisis and the ensuing buildup in public indebtedness, an increasing number of advanced economies have created independent fiscal institutions (IFIs) to improve the quality of public finances and to strengthen the credibility of government policy. A review of Japan’s fiscal policymaking over the past decades suggests that Japan would greatly benefit from establishing an IFI in line with internationally accepted standards of good practice. Such an institution could help correct critical weaknesses in policymaking and anchor expectations, especially if introduced as part of a fiscal framework with a medium-term perspective.
