Systemic Real and Financial Risks: Measurement, Forecasting, and Stress Testing
Description: This paper formulates a novel modeling framework that delivers: (a) forecasts of indicators of systemic real risk and systemic financial risk based on density forecasts of indicators of real activity and financial health; (b) stress-tests as measures of the dynamics of responses of systemic risk indicators to structural shocks identified by standard macroeconomic and banking theory. Using a large number of quarterly time series of the G-7 economies in 1980Q1-2010Q2, we show that the model exhibits significant out-of sample forecasting power for tail real and financial risk realizations, and that stress testing provides useful early warnings on the build-up of real and financial vulnerabilities.

An Assessment of Malaysian Monetary Policy During the Global Financial Crisis of 2008-09
Description: Malaysia was hit hard by the global financial crisis of 2008-09. Anticipating the downturn that would follow the episode of extreme financial turbulence, Bank Negara Malaysia (BNM) let the exchange rate depreciate as capital flowed out, and preemptively cut the policy rate by 150 basis points. Against this backdrop, this paper tries to quantify how much deeper the recession would have been without the BNM's monetary policy response. Taking the most intense year of the crisis as our baseline (2008:Q4-2009:Q3), counterfactual simulations indicate that rather the actual outcome of a -2.9 percent contraction, growth would have been -3.4 percent if the BNM had not implemented countercyclical and discretionary interest rate cuts. Furthermore, had a fixed exchange rate regime been in place, simulations indicate that output would have contracted by -5.5 percent over the same four-quarter period. In other words, exchange rate flexibility and the interest rate cuts implemented by the BNM helped substantially soften the impact of the global financial crisis on the Malaysian economy. These counterfactual experiments are based on a structural model estimated using Malaysian data.

Barbados: Sectoral Balance Sheet Mismatches and Macroeconomic Vulnerabilities
Description: This paper uses the balance sheet approach to analyze macroeconomic vulnerabilities in Barbados between 2006 and 2009. It discusses the financial position of the economy and its main sectors and the sectors' exposure to changes in exchange rates. The main finding of the analysis is that the balance sheet of the aggregate economy has been weakened by the recent deterioration in the balance sheet of the nonfinancial public sector. Macroeconomic vulnerabilities have increased in Barbados since 2006 due to the high public debt and the deterioration in the net financial position with nonresidents. The private sector, however, maintained a healthy position and seems resilient to shocks. The paper also finds the balance sheet of the nonfinancial public sector has deteriorated significantly reflecting weak fiscal performance. While the central government is highly vulnerable to exchange rate shock, debt rollover risks are likely to be limited since most of external liabilities are long term and most domestic liabilities are held by the National Insurance System.

Pricing of Sovereign Credit Risk: Evidence From Advanced Economies During the Financial Crisis
Description: We investigate the pricing of sovereign credit risk over the period 2008-2010 for selected advanced economies by examining two widely-used indicators: sovereign credit default swap (CDS) and relative asset swap (RAS) spreads. Cointegration analysis suggests the existence of an imperfect market arbitrage relationship between the cash (RAS) and the derivatives (CDS) markets, with price discovery taking place in the latter. Likewise, panel regressions aimed at uncovering the fundamental drivers of the two indicators show that the CDS market, although less liquid, has provided a better signal for sovereign credit risk during the period of the recent financial crisis.

Prudential Liquidity Regulation in Developing Countries: A Case Study of Rwanda
Description: This paper analyses the prudential liquidity management framework, in particular the quantitative indicators employed by the central bank of Rwanda in response to the domestic liquidity crisis in 2008/09. It emphasises that the quantitative methods used in the monitoring and assessment of systemic liquidity risk are inadequate because they did not signal the liquidity crises ex-post. There are quick gains to be made from augumenting the liquidity risk indicators with more dynamic liquidity stress tests so that compliance will be achieved through lengthening the maturities of both assets and liabilities on the balance sheet as opposed to simply holding more liquid assets. The paper recommends that policy emphasis shift toward reforms that strengthen systemic liquidity risk assesment, monetary policy implementation as well as improve the efficiency of Rwanda's financial system.

Central Banks Quasi-Fiscal Policies and Inflation
Description: Although central banks have recently taken unconventional policy actions to try to shore up macroeconomic and financial stability, little theory is available to assess the consequences of such measures. This paper offers a theoretical model with which such policies can be analyzed. In particular, the paper shows that in the absence of the fiscal authorities' full backing of the central bank's balance sheet, strange things can happen. For instance, an exit from quantitative easing could be inflationary and central banks cannot successfully unwind inflated balance sheets. Therefore, the fiscal authorities' full backing of the monetary authorities' quasi-fiscal operations is a pre-condition for effective monetary policy.

Can International Macroeconomic Models Explain Low-Frequency Movements of Real Exchange Rates?
Description: Real exchange rates exhibit important low-frequency fluctuations. This makes the analysis of real exchange rates at all frequencies a more sound exercise than the typical business cycle one, which compares actual and simulated data after the Hodrick-Prescott filter is applied to both. A simple two-country, two-good model, as described in Heathcote and Perri (2002), can explain the volatility of the real exchange rate when all frequencies are studied. The puzzle is that the model generates too much persistence of the real exchange rate instead of too little, as the business cycle analysis asserts. Finally, we show that the introduction of adjustment costs in production and in portfolio holdings allows us to reconcile theory and this feature of the data.

Foreign Banks: Trends, Impact and Financial Stability
Description: This paper introduces a comprehensive database on bank ownership for 137 countries over 1995-2009, and reviews foreign bank behavior and impact. It documents substantial increases in foreign bank presence, with many more home and host countries. Current market shares of foreign banks average 20 percent in OECD countries and 50 percent elsewhere. Foreign banks have higher capital and more liquidity, but lower profitability than domestic banks do. Only in developing countries is foreign bank presence negatively related with domestic credit creation. During the global crisis foreign banks reduced credit more compared to domestic banks, except when they dominated the host banking systems.

Oil Exporters' Dilemma: How Much to Save and How Much to Invest
Description: Policymakers in oil-exporting countries confront the question of how to allocate oil revenues among consumption, saving, and investment in the face of high income volatility. We study this allocation problem in a precautionary saving and investment model under uncertainty. Consistent with data in the 2000s, precautionary saving is sizable and the marginal propensity to consume out of permanent shocks is below one, in stark contrast to the predictions of the perfect foresight model. The optimal investment rate is high if productivity in the tradable sector is high enough.

Bank of Japan's Quantitative and Credit Easing: Are they Now More Effective
Description: This paper asks whether the BoJ's recent experience with unconventional monetary easing has been effective in supporting economic activity and inflation. Using a structural VAR model, the paper finds some evidence that BoJ's monetary policy measures during 1998-2010 have had an impact on economic activity but less so on inflation. These results are stronger than those in earlier studies looking at the quantitative easing period up to 2006 and may reflect more effective credit channel as a result of improvements in the banking and corporate sectors. Nevertheless, the relative contribution of monetary policy measures to the variation in output and inflation is rather small.
