Bank Capital and Uncertainty
Description: An important role for bank capital is that of a buffer against unexpected losses. As uncertainty about these losses increases, the theory predicts an increase in the optimal level of bank capital. This paper investigates this implication empirically with U.S. Commercial Banks data and finds statistically significant and robust evidence supporting it. A counterfactual experiment suggests that a decline in uncertainty to the lowest level measured in the sample generates an average reduction in bank capital ratios of slightly over 1 percentage point. However, I also find suggestive evidence that the intensity of this precautionary motive is stronger during recessions. From a policy perspective, these results suggest that the effectiveness of countercyclical capital requirements during bad times will be undermined by banks desire to hold more capital in response to increased uncertainty.

Information Content of DQAF Indicators: Empirical Entropy Analysis
Description: The study presents an analysis of the information content of IMF’s Data Quality Assessment Framework (DQAF) indicators. There are significant differences in the quantity of information between DQAF dimensions and sub-dimensions. The most informative DQAF dimension is accessibility, followed by the prerequisites of quality and accuracy and reliability. The least informative DQAF dimensions are serviceability and assurances of integrity. The implication of these findings is that the current DQAF indicators do not maximize the amount of information that could be obtained during data ROSC missions. An additional set of assessments that would refine the existing DQAF indicators would be beneficial in maximizing the information gathered during data ROSC mission. The entropy of DQAF indicators could also be used in the construction of a cardinal index of data quality.

Can Global Liquidity Forecast Asset Prices?
Description: During the period leading up to the global financial crisis many asset classes registered rapid price increases. This coincided with a significant rise in global liquidity. This paper attempts to determine the extent to which the rise in asset prices was influenced by developments in global liquidity. We confirm that global liquidity had a significant impact on the buildup in house prices; however, the impact on equity prices was limited. In contrast to common perception, we find that the impact of global liquidity declined during the period of the Great Moderation. The paper also examines spillovers from global liquidity to domestic variables and concludes that domestic factors generally played a more significant role in house price appreciation relative to global factors. This contradicts the hypothesis of weakened potency of domestic monetary policy in the presence of increased international liquidity.

A Macro Model of the Credit Channel in a Currency Union Member: The Case of Benin
Description: This paper applies and extends a theoretical model built by Agénor and Montiel (2007) by exploring the effectiveness of government bonds and monetary policy in a small, open, credit-based economy with a fixed exchange rate. The model is applied to Benin, a member of a currency union, using a general equilibrium model with stochastic simulation. Model calibration replicates the historical pattern for 1996–2009. Policy experiments simulated an increase in government securities in Benin’s regional market and a cut in the reserve requirement. Simulations produced mixed results. It appears that, among other factors, excess bank liquidity lowers the effectiveness of monetary policy instruments through the credit channel and that government bonds can help mop up excess bank liquidity.

Dedollarization
Description: This paper provides a summary of the key policies that encourage dedollarization. It focuses on cases in which the authorities’ intention is to gain greater control of monetary policy and draws on the experiences of countries that have successfully dedollarized. Unlike previous work on the subject, this paper examines both macroeconomic stabilization policies and microeconomic measures, such as prudential regulation of the financial system. This study is also the first attempt to make extensive use of the foreign exchange regulation data reported in the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions. The main conclusion is that durable dedollarization depends on a credible disinflation plan and specific microeconomic measures.

Determinants of Foreign Direct Investment: A Sectoral and Institutional Approach
Description: Using a dataset which breaks down FDI flows into primary, secondary and tertiary sector investments and a GMM dynamic approach to address concerns about endogeneity, the paper analyzes various macroeconomic, developmental, and institutional/qualitative determinants of FDI in a sample of emerging market and developed economies. While FDI flows into the primary sector show little dependence on any of these variables, secondary and tertiary sector investments are affected in different ways by countries’ income levels and exchange rate valuation, as well as development indicators such as financial depth and school enrollment, and institutional factors such as judicial independence and labor market flexibility. Finally, we find that the effect of these factors often differs between advanced and emerging economies.

Output and Unemployment Dynamics during the Great Recession: A Panel Unobserved Components Analysis
Description: This paper analyzes the sources of output and unemployment dynamics in the world economy during the Great Recession. This analysis is based on a panel unobserved components model of the world economy, disaggregated into its fifteen largest national economies. We find that excess supply pressure was primarily transmitted from the output market to the labor market by economy specific combinations of negative domestic or foreign output demand shocks, mitigated to varying degrees by countercyclical labor market policies or institutions.

A Monetary Policy Model Without Money for India
Description: A New Keynesian model estimated for India yields valuable insights. Aggregate demand reacts to interest rate changes with a lag of at least three quarters, with inflation taking seven quarters to respond. Inflation is inertial and persistent when it sets in, irrespective of the source. Exchange rate pass-through to domestic inflation is low. Inflation turns out to be the dominant focus of monetary policy, accompanied by a strong commitment to the stabilization of output. Recent policy actions have raised the effective policy rate, but the estimated neutral policy rate suggests some further tightening to normalize the policy stance.

Is Exchange Rate Stabilization an Appropriate Cure for the Dutch Disease?
Description: This paper evaluates how successful is a policy of exchange rate stabilization to counteract the negative effects of a Dutch Disease episode. We consider a small open economy model that incorporates nominal rigidities and a learning-by-doing externality in the tradable sector. The paper shows that leaning against an appreciated exchange rate can prevent an inefficient loss of tradable output but at the cost of generating a misallocation of resources in other sectors of the economy. The paper also finds that welfare is a decreasing function of exchange rate intervention. These results suggest that stabilizing the nominal exchange rate in response to a Dutch Disease episode is highly distortionary.

A New Framework to Estimate the Risk-Neutral Probability Density Functions Embedded in Options Prices
Description: Building on the widely-used double-lognormal approach by Bahra (1997), this paper presents a multi-lognormal approach with restrictions to extract risk-neutral probability density functions (RNPs) for various asset classes. The contributions are twofold: first, on the technical side, the paper proposes useful transformation/restrictions to Bahra’s original formulation for achieving economically sensible outcomes. In addition, the paper compares the statistical properties of the estimated RNPs among major asset classes, including commodities, the S&P 500, the dollar/euro exchange rate, and the US 10-year Treasury Note. Finally, a Monte Carlo study suggests that the multi-lognormal approach outperforms the double-lognormal approach.
