Current Account Norms in Natural Resource Rich and Capital Scarce Economies
Description: The permanent income hypothesis implies that frictionless open economies with exhaustible natural resources should save abroad most of their resource windfalls and, therefore, feature current account surpluses. Resource-rich developing countries (RRDCs), on the other hand, face substantial development needs and tight external borrowing constraints. By relaxing these constraints and providing a key financing source for public investment in RRDCs, temporary resource revenues might then be associated with current account deficits, or at least low surpluses. This paper develops a neoclassical model with private and public investment and several frictions that capture pervasive features in RRDCs, including absorptive capacity constraints, inefficiencies in investment, and borrowing constraints that can be relaxed when natural resources lower the country risk premium. The model is used to study the role of investment and these frictions in shaping the current account dynamics under windfalls. Since consumption and investment decisions are optimal, the model also serves to provide current account benchmarks (norms). We apply the model to the Economic and Monetary Community of Central Africa and discuss how our results can be used to inform the current account norm analysis pursued at the International Monetary Fund.

Hitchhiker’s Guide to Inflation in Libya
Description: This paper presents an empirical investigation of inflation dynamics in Libya over the period 1964–2010, using cointegration and error correction models. While inflation inertia is found to be a key determinant of consumer price inflation, the econometric results indicate that government spending, money supply growth, global inflation, and exchange rate pass-through play central roles in the inflation process. These findings are broadly consistent with the experience of other countries that are natural resource dependent. We also find evidence that the imposition and subsequent removal of international sanctions on Libya had a noteworthy impact on consumer price inflation. Collectively, our estimates indicate that the deviations from an equilibrium path initiate significant adjustments in inflation dynamics, and that closer coordination between monetary and fiscal policies would improve the balance between economic growth and price stability.

The Global Financial Crisis: An Anatomy of Global Growth
Description: The global financial crisis was a stark reminder of the importance of cross-country linkages in the global economy. We document growth synchronization across a diverse group of 185 countries covering 7 regions, and pay particular attention to the period around the global financial crisis. A dynamic factor model is used to decompose each country’s growth into contributions from global, regional, and idiosyncratic shocks. We find a high degree of global synchronization over 1990 to 2011, particularly across advanced economies. Examining the period around the global financial crisis, we find global shocks had large and widespread effects on growth, with more diversity in growth experiences in the early part of the recovery. In a recursive experiment, we find rising global growth synchronization just prior to the crisis, largely resulting from a shift in the importance of global shocks between countries. In contrast, the crisis period caused a much more widespread increase in growth synchronization, and was followed by a similarly pervasive decrease in synchronization in the early recovery.

How Effective are Macroprudential Policies in China?
Description: This paper investigates macroprudential policies and their role in containing systemic risk in China. It shows that China faces systemic risk in both the time (procyclicality) and cross-sectional (contagion) dimensions. The former is reflected as credit and asset price risks, while the latter is reflected as the links between the banking sector and informal financing and local government financing platforms. Empirical analysis based on 171 banks shows that some macroprudential policy tools (e.g., the reserve requirement ratio and house-related policies) are useful, but they cannot guarantee protection against systemic risk in the current economic and financial environment. Nevertheless, better-targeted macroprudential policies have greater potential to contain systemic risk pertaining to the different sizes of the banks and their location in regions with different levels of economic development. Complementing macroprudential policies with further reforms, including further commercialization of large banks, would help improve the effectiveness of those policies in containing systemic risk in China.

Rebalancing: Evidence from Current Account Adjustment in Europe
Description: After the 2003-2007 economic boom, European countries with large pre-crisis current account imbalances are undergoing adjustments. Countries are adjusting at different paces and ways reflecting the source and magnitude of imbalances, availability of financing, competitiveness of the tradable sector and external environment. While emerging European countries with large pre-crisis imbalances and a fixed exchange rate regime have seen sharp current account adjustments and a rebound in growth, adjustment in the euro zone periphery countries, which are also carrying a legacy of pre-crisis CA imbalances, has been gradual with difficulties bringing back growth. This paper is an empirical investigation of current account adjustment in Europe with a focus on these two groups, looking at contributions from cyclical and other factors, and seeking to draw policy conclusions.

Aid, Exports, and Growth: A Time-Series Perspective on the Dutch Disease Hypothesis
Description: We use a heterogeneous panel VAR model identified through factor analysis to study the dynamic response of exports, imports, and per capita GDP growth to a “global” aid shock. We find that a global aid shock can affect exports, imports, and growth either positively or negatively. As a result, the relation between aid and growth is mixed, consistent with the ambiguous results in the existing literature. For most countries in the sample, when aid reduces exports and imports, it also reduces growth; and, when aid increases exports and imports, it also increases growth. This evidence is consistent with a DD hypothesis, but also shows that aid-receiving countries are not “doomed” to catch DD.

Non-Performing Loans in CESEE: Determinants and Impact on Macroeconomic Performance
Description: The paper investigates the non-performing loans (NPLs) in Central, Eastern and South-Eastern Europe (CESEE) in the period of 1998–2011. The paper finds that the level of NPLs can be attributed to both macroeconomic conditions and banks’ specific factors, though the latter set of factors was found to have a relatively low explanatory power. The examination of the feedback effects broadly confirms the strong macro-financial linkages in the region. While NPLs were found to respond to macroeconomic conditions, such as GDP growth, unemployment, and inflation, the analysis also indicates that there are strong feedback effects from the banking system to the real economy, thus suggesting that the high NPLs that many CESEE countries currently face adversely affect the pace economic recovery.

Growth Slowdowns and the Middle-Income Trap
Description: The “middle-income trap” is the phenomenon of hitherto rapidly growing economies stagnating at middle-income levels and failing to graduate into the ranks of high-income countries. In this study we examine the middle-income trap as a special case of growth slowdowns, which are identified as large sudden and sustained deviations from the growth path predicted by a basic conditional convergence framework. We then examine their determinants by means of probit regressions, looking into the role of institutions, demography, infrastructure, the macroeconomic environment, output structure and trade structure. Two variants of Bayesian Model Averaging are used as robustness checks. The results—including some that indeed speak to the special status of middle-income countries—are then used to derive policy implications, with a particular focus on Asian economies.

Factors Influencing Emerging Market Central Banks’ Decision to Intervene in Foreign Exchange Markets
Description: Using panel data for 15 economies from 2001-12, I identify determinants of central bank foreign exchange intervention in emerging markets (“EMs”) with flexible to moderately managed exchange rates. Similar to other studies, I find that central banks tend to “lean against the wind,” buying/selling more foreign exchange in response to greater short-run and medium-run appreciation/depreciation pressures. The panel structure provides a framework to test whether other macroeconomic variables influence the different rates of reserve accumulation between economies. In testing other variables, I find evidence of both precautionary and external competitiveness motives for reserve accumulation.

A Framework for Macroprudential Bank Solvency Stress Testing: Application to S-25 and Other G-20 Country FSAPs
Description: The global financial crisis has placed the spotlight squarely on bank stress tests. Stress tests conducted in the lead-up to the crisis, including those by IMF staff, were not always able to identify the right risks and vulnerabilities. Since then, IMF staff has developed more robust stress testing methods and models and adopted a more coherent and consistent approach. This paper articulates the solvency stress testing framework that is being applied in the IMF’s surveillance of member countries’ banking systems, and discusses examples of its actual implementation in FSAPs to 18 countries which are in the group comprising the 25 most systemically important financial systems (“S-25”) plus other G-20 countries. In doing so, the paper also offers useful guidance for readers seeking to develop their own stress testing frameworks and country authorities preparing for FSAPs. A detailed Stress Test Matrix (STeM) comparing the stress test parameters applie in each of these major country FSAPs is provided, together with our stress test output templates.
