Credibility and Crisis Stress Testing
Description: Credibility is the bedrock of any crisis stress test. The use of stress tests to manage systemic risk was introduced by the U.S. authorities in 2009 in the form of the Supervisory Capital Assessment Program. Since then, supervisory authorities in other jurisdictions have also conducted similar exercises. In some of those cases, the design and implementation of certainelements of the framework have been criticized for their lack of credibility. This paper proposes a set of guidelines for constructing an effective crisis stress test. It combines financial markets impact studies of previous exercises with relevant case study information gleaned from those experiences to identify the key elements and to formulate their appropriate design. Pertinent concepts, issues and nuances particular to crisis stress testing are also discussed. The findings may be useful for country authorities seeking to include stress tests in their crisis management arsenal, as well as for the design of crisis programs.

HEAT! A Bank Health Assessment Tool
Description: Developments during the global financial crisis have highlighted the importance of differentiating across financial systems and institutions. Assessments of financial stability have increasingly considered the characteristics of individual banks within a financial system, as well as those with significant international reach, to identify vulnerabilities and inform policy decisions. This paper proposes a simple measure of bank soundness, the Bank Health Index (BHI), to facilitate preliminary analyses of individual financial institutions relative to their peers. The evidence suggests that the BHI is useful for a first-pass identification of bank soundness conditions. Automated spreadsheet templates of the bank Health Assessment Tool (HEAT!) are provided for users with access to the BankScope, Bloomberg and/or SNL database(s).

Benchmarking Structural Transformation Across the World
Description: This paper documents stylized facts on the process of structural transformation around the world and empirically analyzes its determinants using data on real value added by sector of economic activity (agriculture, manufacturing and services) for a panel of 168 countries over the period 1970-2010. The analysis points to large differences in sector shares both across and within regions as well as for countries at similar levels of economic development. Using both linear and quantile regression methods, it finds that a large proportion of the cross-country variation in sector shares can be accounted for by country characteristics, such as real GDP per capita, demographic structure, and population size. It also finds that policy and insitutional variables, such as product market reforms, openness to trade, human and physical capital, and finance improve the baseline model’s ability to account for the variation in sectoral shares across countries.

Financial Interconnectedness and Financial Sector Reforms in the Caribbean
Description: Financial sector linkages have increased continuously in the Caribbean with cross border capital flows and financial conglomerates dominating the financial system. While the greater interconnectedness can heighten systemic risks and likelihood of contagion, it can have positive impacts provided the regional authorities take steps to prevent the systemic risk. In this context, financial sector reform measures aimed at bolstering and harmonizing prudential regulations in line with international best practices, the strengthening and enhancement of financial sector supervision to include cross border linkages through consolidated supervision, increased cooperation across supervisors in the region, and the establishment of deposit insurance and crisis resolution frameworks will be critical to maintain financial sector stability and minimize the repercussions of any negative shocks.

Sudden stops, time inconsistency, and the duration of sovereign debt
Description: We study the sovereign debt duration chosen by the government in the context of a standard model of sovereign default. The government balances off increasing the duration of its debt to mitigate rollover risk and lowering duration to mitigate the debt dilution problem. We present two main results. First, when the government decides the debt duration on a sequential basis, sudden stop risk increases the average duration by 1 year. Second, we illustrate the time inconsistency problem in the choice of sovereign debt duration: governments would like to commit to a duration that is 1.7 years shorter than the one they choose when decisions are made sequentially.

Tax Administration Reform in the Francophone Countries of Sub-Saharan Africa
Description: Since the early 1990s, major tax administration reforms have been implemented in the Francophone countries of sub-Saharan Africa, with significant support from the IMF and development partners. While the reforms have contributed to an increase in revenues, attention is still needed to address a number of weaknesses in these countries’ tax administrations. A review of the conditions for successful modernization of the tax administration shows that significant changes are needed to ensure better utilization of technical assistance, improve the governance of reforms, and provide the tax administrations with greater flexibility in managing their resources.

Bank Resolution Costs, Depositor Preference, and Asset Encumbrance
Description: Depositor preference and collateralization of borrowing may reduce the cost of settling the conflicts among creditors that arises in case of resolution or bankruptcy. This net benefit, which may be capitalized into the value of the bank rather than affect creditors’ expected returns, should result in lower overall funding costs and thus a lower probability of distress despite increasing encumbrance of the bank’s balance sheet. The benefit is maximized when resolution is initiated early enough for preferred depositors to remain fully protected.

What Explains Movements in the Peso/Dollar Exchange Rate?
Description: This paper examines the factors affecting the weekly peso/dollar exchange rate movements between 1999 and 2013 using an error correction model. The model fits the historical data well. While copper price is the most important determinant of the peso exchange rate over the long run, other factors including interest rate differential, global financial distress, local pension funds’ derivative position, as well as the Federal Reserve’s quantitative easing also affect the peso in the short run. The Central Bank of Chile’s foreign exchange interventions in 2008 and 2011 had a small impact on the peso.

The Macroprudential Framework: Policy Responsiveness and Institutional Arrangements
Description: This paper gauges if, and how, institutional arrangements are correlated with the use of macroprudential policy instruments. Using data from 39 countries, the paper evaluates policy response time in various types of institutional arrangements for macroprudential policy and finds that the macroprudential framework that gives the central bank an important role is associated with more timely use of macroprudential policy instruments. Policymakers may also tend to use macroprudential instruments more quickly if the ability to conduct monetary policy is somehow constrained. This finding points to the importance of coordination between macroprudential and monetary policy.

Institutional Arrangements for Macroprudential Policy in Asia
Description: This paper surveys institutional arrangements for macroprudential policy in Asia. Central banks in Asia typically have a financial stability mandate, and play a key role in the macroprudential framework. Smaller and more open economies with prudential regulation inside the central bank tend to have institutional arrangements that give the central bank a leading role. In larger and more complex economies where prudential regulation is outside the central bank, the financial stability mandate is usually shared with other agencies and the government tends to play a leading role. Domestic policy coordination is typically performed by a financial stability committee/other coordination body while cross-border cooperation is largely governed by Memoranda of Understanding.
