Accounting for Output Drops in Latin America
Description: This paper evaluates what type of models can account for the recent episodes of output drops in Latin America. I develop an open economy version of the business cycle accounting methodology (Chari, Kehoe, and McGrattan, 2007) in which output fluctuations are decomposed into four sources: total factor productivity (TFP), a labor wedge, a capital wedge, and a bond wedge. The paper shows that the most promising models are the ones that induce fluctuations of TFP and the labor wedge. On the other hand, models of fnancial frictions that translate into a bond or capital wedge are not successful in explaining output drops in Latin America. The paper also discusses the implications of these results for policy analysis using alternative DSGE models.

Global Imbalances: The Role of Emerging Asia
Description: This paper investigates the role played by emerging Asia in the emergence and evolution of the global trade imbalances. Based on simulations in a general equilibrium model of the world economy, we find that a productivity slowdown in the non-tradable sector of these economies in the second half of the 1990s fits regional macroeconomic developments relatively well, but has limited spillover effect to the United States trade balance. In contrast, an increase in the desired level of emerging Asia net foreign assets starting in 2001 not only fits regional developments relatively well, but also has a significant spillover effect to the United States.

The Use (and Abuse) of CDS Spreads During Distress
Description: Credit Default Swap spreads have been used as a leading indicator of distress. Default probabilities can be extracted from CDS spreads, but during distress it is important to take account of the stochastic nature of recovery value. The recent episodes of Landbanski, WAMU and Lehman illustrate that using the industry-standard fixed recovery rate assumption gives default probabilities that are low relative to those extracted from stochastic recovery value as proxied by the cheapest-to-deliver bonds. Financial institutions using fixed rate recovery assumptions could have a false sense of security, and could be faced with outsized losses with potential knock-on effects for other institutions. To ensure effective oversight of financial institutions, and to monitor the stability of the global financial system especially during distress, the stochastic nature of recovery rates needs to be incorporated.

Targeting Social Transfers to the Poor in Mexico
Description: Mexico’s main social support program, Oportunidades, combines two methods to target cash to poor households: an initial self-selection by households who acquire knowledge about the program and apply for benefits, followed by an administrative determination of eligibility based on a means test. Self-selection improves targeting by excluding high-income households, while administrative targeting does so mainly by excluding middle-income households. The two methods are complementary: expanding program knowledge across households substantially increases applications from non-poor households, thus reinforcing the importance of administrative targeting. The paper shows that targeting can be further improved through redesigning the means test and differentiating transfers according to demographic characteristics.

A Primeron Fiscal Analysis in Oil-Producing Countries
Description: This paper proposes an integrated approach to fiscal policy analysis in oil producing countries (OPCs) geared towards addressing their unique and complex policy challenges. First, an accurate assessment of the fiscal stance in OPCs can be obscured by large and volatile oil revenue flows. Second, uncertain and volatile oil revenue flows can complicate the management of macroeconomic policies in these countries. Third, given the exhaustibility of oil reserves, OPCs need to address longer-term sustainability and intergenerational equity issues. The use of non-oil fiscal indicators, stress tests, medium-term frameworks, and permanent oil income models can greatly aid in addressing these challenges.

Global Liquidity, Risk Premiums and Growth Opportunities
Description: This paper constructs new indicators of liquidity for equity, bond and money markets in major advanced and emerging market countries, documents their evolution and comovements, and assesses the extent to which such measures are determinants of selected spreads and proxy measures of countries' growth opportunities. Three main results obtain. First, there is evidence of an historical increase in market liquidity since the early 1990s, in part as a result of advances in international financial integration, but markets have been increasingly exposed to global systemic liquidity shocks. Second, liquidity indicators appear to be important determinants of bond spreads in advanced economies and EMBI spreads in emerging markets. Third, improvements in market liquidity have significant real effects, as liquidity indicators have a significant positive impact on proxy measures of countries' growth opportunities.

Fiscal and Monetary Policy During Downturns: Evidence From the G7
Description: This paper analyzes how fiscal and monetary policy typically respond during downturns in G7 countries. It evaluates whether discretionary fiscal responses to downturns are timely and temporary, and compares the response of fiscal policy to that of monetary policy. The results suggest that while responding more weakly and less quickly than monetary policy, discretionary fiscal policy is more timely than conventional wisdom would suggest, particularly in “Anglo-Saxon” countries, but the response differs substantially across fiscal instruments. Both fiscal and monetary policy are found to be subject to an easing bias, with more easing during downturns than tightening during upturns; and liable to easing in response to erroneously perceived downturns, many of which are subsequently revised to expansions.

The Second Transition: Eastern Europe in Perspective
Description: The countries of Eastern Europe achieved two remarkable transitions in the short period of the last two decades: from plan to market and, then, in the run-up to and entry into the European Union, they rode a wave of global trade and financial market integration. Focusing on the second transition, this paper reaches three conclusions. First, by several metrics, East European and East Asian growth performances were about on par from the mid-1990s; both regions far surpassed Latin American growth. Second, the mechanisms of growth in East Europe and East Asia were, however, very different. East Europe relied on a distinctive-often discredited-model, embracing financial integration with structural change to compensate for appreciating real exchange rates. In contrast, East Asia contained further financial integration and maintained steady or depreciating real exchange rates. Third, the ongoing financial turbulence has, thus far, not had an obviously differential impact on emerging market regions: rather, the hot spots in each region reflect individual country vulnerabilities. If the East European growth model is distinctive, is it sustainable and replicable? The paper speculates on the possibilities.

Deleveraging After Lehman: Evidence From Reduced Rehypothecation
Description: Rehypothecation is the practice that allows collateral posted by, say, a hedge fund to their prime broker to be used again as collateral by that prime broker for its own funding. In the United Kingdom, such use of a customer’s assets by a prime broker can be for an unlimited amount of the customer’s assets. And moreover, there are no customer protection rules (such as in the United States under the Securities Act of 1933). The paper shows evidence that, following Lehman’s bankruptcy, the extent of rehypothecation has declined substantially, in part because investment firms fear losing collateral if their prime broker becomes insolvent. While less rehypothecation reduces counterparty risk in the system, it also reduces market liquidity.

The Inflation-Unemployment Trade-off at Low Inflation
Description: Wage setters take into account the future consequences of their current wage choices in the presence of downward nominal wage rigidities. Several interesting implications arise. First, a closed-form solution for a long-run Phillips curve relates average unemployment to average wage inflation; the curve is virtually vertical for high inflation rates but becomes flatter as inflation declines. Second, macroeconomic volatility shifts the Phillips curve outward, implying that stabilization policies can play an important role in shaping the trade-off. Third, nominal wages tend to be endogenously rigid also upward, at low inflation. Fourth, when inflation decreases, volatility of unemployment increases whereas the volatility of inflation decreases: this implies a long-run trade-off also between the volatility of unemployment and that of wage inflation.
