The Fundamental Determinants of Credit Default Risk for European Large Complex Financial Institutions
Description: This paper attempts to identify the fundamental variables that drive the credit default swaps during the initial phase of distress in selected European Large Complex Financial Institutions (LCFIs). It uses yearly data over 2004 - 08 for 29 European LCFIs. The results from a dynamic panel data estimator show that LCFIs’ business models, earnings potential, and economic uncertainty (represented by market expectations about the future risks of a particular LCFI and market views on prospects for economic growth) are among the most significant determinants of credit risk. The findings of the paper are broadly consistent with those of the literature on bank failure, where the determinants of the latter include the entire CAMELS structure - that is, Capital Adequacy, Asset Quality, Management Quality, Earnings Potential, Liquidity, and Sensitivity to Market Risk. By establishing a link between the financial and market fundamentals of LCFIs and their CDS spreads, the paper offers a potential tool for fundamentals-based vulnerability and early warning system for LCFIs.

Monetary Policy Analysis and Forecasting in the Group of Twenty: A Panel Unobserved Components Approach
Description: This paper develops a panel unobserved components model of the monetary transmission mechanism in the world economy, disaggregated into twenty national economies along the lines of the Group of Twenty. This structural macroeconometric model features extensive linkages between the real and financial sectors, both within and across economies. A variety of monetary policy analysis and forecasting applications of the estimated model are demonstrated, based on a Bayesian framework for conditioning on judgment.

Procyclicality in Central Bank Reserve Management: Evidence from the Crisis
Description: A decade-long diversification of official reserves into riskier investments came to an abrupt end at the beginning of the global financial crisis, when many central bank reserve managers started to withdraw their deposits from the banking sector in an apparent flight to quality and safety. We estimate that reserve managers pulled around US$500 billion of deposits and other investments from the banking sector. Although clearly not the main cause, this procyclical investment behavior is likely to have contributed to the funding problems of the banking sector, which required offsetting measures by other central banks such as the Federal Reserve and Eurosystem central banks. The behavior highlights a potential conflict between the reserve management and financial stability mandates of central banks. This paper analyzes reserve managers’ actions during the crisis and draws some lessons for strategic asset allocation of reserves going forward.

Balance Sheet Vulnerabilities of Mauritius During a Decade of Shocks
Description: After reviewing the economic reform strategy of Mauritius for the past 10 years in the face of several external shocks, we apply a balance sheet analysis (BSA) focusing on currency, maturity, and intersectoral mismatches. In reviewing developments over this decade, we find that the currency and maturity mismatches have fallen across various sectors, and the intersectoral risks to each analyzed sector’s balance sheet appear controllable. The government has implemented reforms in recent years that have contributed to general improvement in the balance sheet of the Mauritian economy and its subsectors. We conclude that from a BSA perspective, the macroeconomic vulnerabilities of Mauritius seem manageable, though vulnerabilities remain, and data gaps mean that more work will be needed to support these findings.

Inflation Dynamics in Yemen: An Empirical Analysis
Description: Yemen has had a high and volatile rate of inflation in recent years. This paper studies the underlying determinants of inflation dynamics in Yemen using three different approaches: (i) a single equation model, (ii) a Structural Vector Autoregression Model, and (iii) a Vector Error Correction Model. The outcomes suggest that inflation dynamics in Yemen are driven by international price shocks, exchange rate depreciation, domestic demand shocks, and monetary innovations. The impact of international prices and exchange rate depreciation indicate a significant pass-through of import prices. In the short run, external shocks of international prices and the exchange rate account for most variations in inflation, but domestic shocks to money supply and domestic demand explain larger variations in the medium term.

Tax Revenue Downturns: Anatomy and Links to Imports
Description: We study historical tax revenue downturn episodes—where tax revenue-to-GDP ratios decline sharply—and explore the link between tax revenues and imports. We document that downturn episodes of at least 1 percentage point of GDP in one year are common. The tax types that account for these episodes are different in advanced, emerging and developing, and oil producing countries. We find that tax revenue downturns and import contractions have a statistically significant link. Finally, we show that changes in imports are a statistically significant determinant of changes in tax revenues even when controlling for changes in the output gap and in the terms of trade.

In Search of Lost Revenue: Why Restoring Fiscal Soundness After a Crisis is Harder Than it Looks
Description: This note argues that because fiscal deficit after a crisis owe much to a drop in tax revenues and a sluggish revenue growth, its adjustment has to rely more on revenue augmentation than commonly thought. Cutting extra spending in the wake of the crisis would not balance the book, while a natural growth of tax revenue after the recovery may take a long time before financing the pre-crisis level of expenditure. Faced with unpopular choices, the government may implicitly prefer seeing higher inflation.

Banking Efficiency and Financial Development in Sub-Saharan Africa
Description: This study assesses the determinants of banking system efficiency in sub-Saharan Africa (SSA) and asks what, besides the degree of efficiency, explains the low level of financial development in the region. It uses stochastic frontier analysis to measure efficiency and a generalized method of moments system to explain financial development. SSA banks are found to be generally cost-efficient, but nonperforming loans undermine efficiency, which suggests that improvement in the regulatory and credit environments should improve efficiency. The political and the economic environment have held back financial development in SSA.

How Expensive is Norway? New International Relative Price Measures
Description: In this paper, we derive two new measures of international relative prices for Norway. Developments in these new measures follow rather closely movements in the CPI-based real effective exchange rate through the 1990s, but diverge after 2000—suggesting that the costs of living in Norway relative to its trading partners have risen in the recent years more than the real effective exchange rate would indicate.

Sovereign Spreads: Global Risk Aversion, Contagion or Fundamentals?
Description: Over the past year, euro area sovereign spreads have exhibited an unprecedented degree of volatility. This paper explores how much of these large movements reflected shifts in (i) global risk aversion (ii) country-specific risks, directly from worsening fundamentals, or indirectly from spillovers originating in other sovereigns. The analysis shows that earlier in the crisis, the surge in global risk aversion was a significant factor influencing sovereign spreads, while recently country-specific factors have started playing a more important role. The perceived source of contagion itself has changed: previously, it could be found among those sovereigns hit hard by the financial crisis, such as Austria, the Netherlands, and Ireland, whereas lately the countries putting pressure on euro area government bonds have been primarily Greece, Portugal, and Spain, as the emphasis has shifted towards short-term refinancing risk and long-term fiscal sustainability. The paper concludes that debt sustainability and appropriate management of sovereign balance sheets are necessary conditions for preventing sovereign risk from feeding back into broader financial stability concerns.
