Measuring Systemic Liquidity Risk and the Cost of Liquidity Insurance
Description: I construct a systemic liquidity risk index (SLRI) from data on violations of arbitrage relationships across several asset classes between 2004 and 2010. Then I test whether the equity returns of 53 global banks were exposed to this liquidity risk factor. Results show that the level of bank returns is not directly affected by the SLRI, but their volatility increases when liquidity conditions deteriorate. I do not find a strong association between bank size and exposure to the SLRI - measured as the sensitivity of volatility to the index. Surprisingly, exposure to systemic liquidity risk is positively associated with the Net Stable Funding Ratio (NSFR). The link between equity volatility and the SLRI allows me to calculate the cost that would be borne by public authorities for providing liquidity support to the financial sector. I use this information to estimate a liquidity insurance premium that could be paid by individual banks in order to cover for that social cost.

Latin America: Vulnerabilities Under Construction?
Description: This paper documents developments in mortgage credit and the housing sector in Latin America over the past decade, and compares them with those of other emerging economies. In particular, it examines the real estate and mortgage markets to assess whether (i) growth in mortgage credit is excessive compared to long-term trends; (ii) trends in house prices reflect changes in economic fundamentals; and (iii) the extent to which household and banking sector vulnerabilities could lead to potential fragilities. Although data limitations hamper a rigorous analysis of trends, our analysis suggests that while there are no imminent misalignments in the real estate and mortgage sectors, they could emerge if current trends persist. Strengthening supervision and addressing data gaps is thus critical to ensure adequate monitoring of risks and vulnerabilities in these sectors.

Lost in Transmission? The Effectiveness of Monetary Policy Transmission Channels in the GCC Countries
Description: This paper empirically investigates the effectiveness of monetary policy transmission in the Gulf Cooperation Council (GCC) countries using a structural vector autoregressive model. The results indicate that the interest rate and bank lending channels are relatively effective in influencing non-hydrocarbon output and consumer prices, while the exchange rate channel does not appear to play an important role as a monetary transmission mechanism because of the pegged exchange rate regimes. The empirical analysis suggests that policy measures and structural reforms - strengthening financial intermediation and facilitating the development of liquid domestic capital markets - would advance the effectiveness of monetary transmission mechanisms in the GCC countries.

Successful Austerity in the United States, Europe and Japan
Description: The output effects of 2009 fiscal expansions have been hotly debated. But the discussion of fiscal multipliers is even more relevant now that several European countries have had to quickly retract their stimulus measures in an effort to regain market confidence. Using regime-switching VARs we estimate the impact of fiscal adjustment on the United States, Europe and Japan allowing for fiscal multipliers to vary across recessions and booms. We also estimate ex ante probabilities of recessions derived in association with different-sized and different types of consolidation shocks (expenditure- versus tax-based). We use these estimates to understand how consolidations should be designed to be most effective in terms of permanently and rapidly reducing a country’s debt-to-GDP ratio. The main finding is that smooth and gradual consolidations are to be preferred to frontloaded or aggressive consolidations, especially for economies in recession facing high risk premia on public debt, because sheltering growth is key to the success of fiscal consolidation in these cases.

On Price Stability and Welfare
Description: The financial crisis in the advanced countries that began in 2007 has led central bankers to adopt unconventional policy measures as policy interest rates neared the zero bound. One suggestion (Blanchard, Dell’Ariccia, and Mauro, 2010) has been to raise inflation targets to provide more room for policy rate easing during crises. This paper addresses a different issue: the relationship between inflation and welfare. The literature is surveyed and a model is developed. A key conclusion is that an increase in inflation targets gives rise to additional welfare costs, even after the extra room to maneuver above the zero lower bound for nominal policy rates is taken into account. Based on parameter values that fit U.S. data, the additional welfare costs of raising inflation targets from 2 to 4 percent are estimated at about 0.3 percent of annual real income. A rise to 10 percent would yield additional welfare costs of about 1 percent of real income. Other parameter values yield welfare costs as high as 7 (respectively 30) percent of real income for raising inflation targets from 2 to 4 (respectively from 2 to 10) percent. The full costs of raising inflation targets are likely to be higher because the model used to generate these estimates does not account for higher inflation-induced volatility.

Riding Global Financial Waves: The Economic Impact of Global Financial Shocks on Emerging Market Economies
Description: Over the past two decades, most emerging market economies witnessed two key developments. A marked process of financial integration with the rest of the world, arguably turning these economies more vulnerable to global financial shocks; and an improvement of macroeconomic fundamentals, helping to increase their resiliency to these shocks. Against a backdrop of these opposing forces, are these economies more vulnerable to global financial shocks today than in the past? Have better fundamentals offset increasing financial integration? If so, what fundamentals matter most? We address these questions by examining the role of these two forces over the past two decades in amplifying or buffering the economic impact of these shocks. Our findings show that EMEs, with the exception of Emerging Europe, have become less vulnerable. Exchange rate flexibility and external sustainability are key determinants of the impact of these shocks, while the extent to which deeper financial integration is a source of vulnerability depends on the exchange rate regime.

Fiscal Rules in Response to the Crisis: Toward the "Next-Generation" Rules: A New Dataset
Description: Strengthening fiscal frameworks, in particular fiscal rules, has emerged as a key response to the fiscal legacy of the crisis. This paper takes stock of fiscal rules in use around the world, compiles a dataset - covering national and supranational fiscal rules, in 81 countries from 1985 to end-March 2012 - and presents details about the rules’ key design elements, particularly in support of enforcement. This information is summarized in a set of fiscal rules indices. Three key findings emerge: (i) many new fiscal rules have been adopted and existing ones strengthened in response to the crisis; (ii) the number of fiscal rules and the comprehensiveness of the design features in emerging economies has caught up to those in advanced economies; and (iii) the "next-generation" fiscal rules are increasingly complex as they combine the objectives of sustainability and with the need for flexibility in response to shocks, thereby creating new challenges for implementation, communication, and monitoring.

Intertwined Sovereign and Bank Solvencies in a Model of Self-Fulfilling Crisis
Description: Large fiscal financing needs, both in advanced and emerging market economies, have often been met by borrowing heavily from domestic banks. As public debt approached sustainability limits in a number of countries, however, high bank exposure to sovereign risk created a fragile inter-dependence between fiscal and bank solvency. This paper presents a simple model of twin (sovereign and banking) crisis that stresses how this interdependence creates conditions conducive to a self-fulfilling crisis.

Estimating the Implicit Inflation Target of the South African Reserve Bank
Description: This paper applies a state-space approach to estimate the implicit inflation target of the South African Reserve Bank (SARB) since the adoption of the Inflation Targeting (IT) framework. The paper's findings are two. First, although the official inflation target range is 3.6 percent, in practice, the SARB seems to have aimed for the upper segment of the band (41.2 .6 percent) for most of the period, despite the substantial variation of the output gap. Second, the estimation results show that the implicit inflation target varied over time, and in recent years it has shifted toward the upper limit of the inflation target range. This perhaps suggests that since the outbreak of the financial crisis in 2008, the SARB's tolerance for higher inflation has somewhat increased to better support economic activity.

Japan out of the Lost Decade: Divine Wind or Firms’ Effort?
Description: A surge of exports in the 2000s helped Japan exit the severe decade-long stagnation known as the lost decade. Using panel data of Japanese exporting firms, we examine the sources of the export surge during this period. One view argues that the so-called "divine wind" or exogenous external demand boosted Japanese exports. The other view emphasizes the role of supply factors such as productivity gains, materialized after long-fought restructuring efforts during the lost decade. Estimating the firm-level export function allows us to assess the relative importance of these demand and supply factors. Evidence shows that firms' efforts were more important than the divine wind.
