Constructing Forecast Confidence Bands During the Financial Crisis
Description: We derive forecast confidence bands using a Global Projection Model covering the United States, the euro area, and Japan. In the model, the price of oil is a stochastic process, interest rates have a zero floor, and bank lending tightening affects the United States. To calculate confidence intervals that respect the zero interest rate floor, we employ Latin hypercube sampling. Derived confidence bands suggest non-negligible risks that U.S. interest rates might stay near zero for an extended period, and that severe credit conditions might persist.

The Effectiveness of Central Bank Interventions During the First Phase of the Subprime Crisis
Description: This paper provides evidence that central bank interventions had a statistically significant impact on easing stress in unsecured interbank markets during the first phase of the subprime crisis which began in July 2007. Extraordinary liquidity provisions, such as the Term Auction Facility by the Federal Reserve, are analyzed. First a decomposition of the Libor-OIS spread indicates that credit premia increased in importance as the crisis deepened. Second, using Markov switching models, central bank operations are then graphically associated with reductions in term funding stress. Finally, bivariate VAR and GARCH models are adopted to econometrically quantified these impacts. While helpful in compressing Libor spreads, the economic magnitudes of central interventions have overall not been very large.

Commodity Terms of Trade: The History of Booms and Busts
Description: We compile a historical dataset covering nearly 40 years of booms and busts in the commodity terms of trade of over 150 countries. We discuss the characteristics of these events and their effects on macroeconomic performance and, in particular, compare the most recent commodity-price cycle with its historical precedents.

The Drivers of Housing Cycles in Spain
Description: Since Spain joined the EMU, two main important factors behind the housing boom appear to be the decrease of nominal interest rates and demographic factors. In this paper we estimate a New Keynesian model of a currency area, using data for Spain and the rest of the EMU to study the importance of those factors. We also examine the role of different rigidities and find that labor market frictions are crucial to explain main features of the data. On the other hand, financial frictions that impose a collateral constraint on borrowing do not appear to be relevant.

The Real Effects of Financial Sector Risk
Description: This paper estimates the magnitude of key effects on the real economy from financial sector stress. We focus on the short-run feedback effect from market-based indicators of financial sector risk to the real economy through the credit channel, and estimate this effect on an economy-wide (macro) level, as well as on the level of individual large banks. Both estimates yield significant feedback effects of substantial magnitude. The estimates are consistent with other work in this area. Our results suggest that prudential supervision could be enhanced by taking into account the feedback effects of financial instability in the real economy. We also propose a way to integrate feedback effects into stress tests in order to improve realism and accuracy or macroeconomic stress scenarios, as well as a metric to interpret stress testing results.

Frugality: Are We Fretting Too Much? Household Saving and Assets in the United States
Description: Household savings rates in the United States have recently crept up from all-time lows. Some have suggested that a shift toward frugality will hamper GDP growth-the Keynesian "paradox of thrift." We estimate that households compensate for a fall in their asset income by saving more out of their labor income, dollar-for-dollar. In the wake of the crisis, our model predicts that such primary savings will increase, but only temporarily and modestly, as household assets stabilize. As savings flows gradually accumulate, they help rebuild corporate net worth and hence firms' capacity to make capital investments. A timely return to pre-crisis levels of capital investment would require that U.S. households save substantially more than the model predicts, starting now. Hence, we should fret that our savings rates may be too low.

The Derivatives Market in South Africa: Lessons for Sub-Saharan African Countries
Description: This paper examines the role of the derivatives market in South Africa and provides policy options for promoting the development of derivatives markets in sub-Saharan Africa. South Africa's derivatives market has grown rapidly in recent years, supporting capital inflows and helping market participants to price, unbundle and transfer risk. There are tight regulations on asset allocations by insurance and pension funds to prevent excessive risk taking. The development of derivatives markets in sub-Saharan African countries could enable market participants to self-insure against volatile capital flows. Theiroverdependence on bank credit as a source of funding could be reduced and their management of seasonal risk could be improved through the introduction of commodity futures. However, these markets must be appropriately regulated and supervised. Since such markets would likely be small, consideration should be given to the establishment of a regional derivatives market.

The Gambia: Demand for Broad Money and Implications for Monetary Policy Conduct
Description: This paper evaluates the demand for broad money (M2) in The Gambia for January 1988-June 2007. There appears to be a long-run relationship for demand for real M2, but the relationship is not stable. Exogenous output shocks, financial innovation, changes in income velocity, and inadequate data quality contribute to the instability. The authorities may need to apply the monetary targeting regime flexibly in the overall objective of preserving price stability. A possible option for The Gambia is to become an inflation targeter lite.

Search in the Labor Market under Imperfectly Insurable Income Risk
Description: This paper develops a general equilibrium model with unemployment and noncooperative wage determination to analyze the importance of incomplete markets when risk-averse agents are subject to idiosyncratic employment shocks. A version of the model calibrated to the U.S. shows that market incompleteness affects individual behavior and aggregate conditions: it reduces wages and unemployment but increases vacancies. Additionally, the model explains the average level of unemployment insurance observed in the U.S. A key mechanism is the joint influence of imperfect insurance and risk aversion in the wage bargaining. The paper also proposes a novel solution to solve this heterogeneous-agent model.

One Money, One Market—A Revised Benchmark
Description: The introduction of the euro generated substantial interest in measuring the impact of currency unions (CUs) on trade flows. Rose's (2000) initial estimates suggested a tripling of trade and created a literature in search of "more reasonable" CU effects. A recent meta-analysis of this literature shows that subsequent papers quantify CU trade impacts at 30-90 percent. However, most recent studies use shorter time series and fewer countries than Rose in his original work. We revisit Rose's original benchmark, extend the dataset, and address Baldwin's (2006) critiques regarding the proper specification of gravity models in large panels by simultaneously accounting for multilateral resistance and unobserved bilateral heterogeneity. This produces a robust average CU trade effect of 45 percent. Yet, the trade impacts of individual CUs vary substantially and are generally lower than those of preferential trade agreements (PTAs). Our revised benchmark can be used as a yardstick for future studies to delineate how estimates differ due to new data or differences in econometric specifications.
