Economic Integration and Financial Stability: A European Perspective
Description: This paper assesses changes in synchronization of real activity and financial market integration in Western Europe and evaluates their implications for financial stability. We find increased synchronization of real activity since the early 1980s and increased equity markets integration since the early 1990s. We also find that measures of systemic risk at large European financial institutions have not declined during the period 1990-2004 and that bank systemic risk profiles have converged. At the same time, the sensitivity of bank and insurance systemic risk measures to common real and financial shocks has increased in most countries. Overall, these results suggest that the integration process does not necessarily entail an unambiguously positive effect on financial stability.

Probabilistic Sustainability of Public Debt: A Vector Autoregression Approach for Brazil, Mexico, and Turkey
Description: This paper examines the sustainability of fiscal policy under uncertainty in three emerging market countries, Brazil, Mexico, and Turkey. For each country, we estimate a vector autoregression (VAR) that includes fiscal and macroeconomic variables. Retrospectively, a historical decomposition shows by how much debt accumulation reflects unsustainable policy, adverse shocks, or both. Prospectively, Monte Carlo techniques reveal the primary surplus that is required to keep the debt/GDP ratio from rising in all but the worst 50 percent, 25 percent, and 10 percent of circumstances. Such a value-at-risk approach presents a clearer menu of policy options than currently used frameworks.

Volatility and Growth in Latin America: An Episodic Approach
Description: This paper compares the pattern of macroeconomic volatility in 17 Latin American countries during episodes of high and low growth since 1970, examining in particular the role of policy volatility. Macroeconomic outcomes are distinguished from macroeconomic policies, structural reforms and reversals, shocks, and institutional constraints. Based on previous work, a composite measure of structural reforms is constructed for the 1970-2004 period. We find that outcomes and policies are more volatile in low growth episodes, while shocks (except U.S. interest rates) are similar across episodes. Fiscal policy volatility is associated with lower growth, but fiscal policy procyclicality is not. Low levels of market-oriented reforms and structural reform reversals are also associated with lower growth.

How Does the Introduction of Health Insurance Change the Equity of Health Care Provision in Bulgaria?
Description: The study examines the effect of health care reform in Bulgaria in 1999 on the equity of health care financing. It explores the distribution of different types of health care financing by income. Furthermore, it separates the financial and social reasons for these differences, dividing them into economic and social inequalities. It suggests a method of distinguishing between financially based and "exclusion based" reasons for having progressive/regressive health care financing. Moreover, it looks at the social factors that shape health expenditure patterns and identifies those social characteristics that lead to exclusion from the health care system.

Portfolio Credit Risk and Macroeconomic Shocks: Applications to Stress Testing Under Data-Restricted Environments
Description: Portfolio credit risk measurement is greatly affected by data constraints, especially when focusing on loans given to unlisted firms. Standard methodologies adopt convenient, but not necessarily properly specified parametric distributions or simply ignore the effects of macroeconomic shocks on credit risk. Aiming to improve the measurement of portfolio credit risk, we propose the joint implementation of two new methodologies, namely the conditional probability of default (CoPoD) methodology and the consistent information multivariate density optimizing (CIMDO) methodology. CoPoD incorporates the effects of macroeconomic shocks into credit risk, recovering robust estimators when only short time series of loans exist. CIMDO recovers portfolio multivariate distributions (on which portfolio credit risk measurement relies) with improved specifications, when only partial information about borrowers is available. Implementation is straightforward and can be very useful in stress testing exercises (STEs), as illustrated by the STE carried out within the Danish Financial Sector Assessment Program.

Uganda: Managing More Effective Decentralization
Description: This Working Paper should not be reported as representing the views of the IMF. The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate. A politically driven and ambitious decentralization program implemented by the authorities since the late 1990s has had mixed results in terms of enhancing service delivery. Paradoxically, concerns with the results of service delivery, partially driven by donors' requirements, have resulted in a deconcentrated system relying on conditional grants and unfunded mandates. This has reduced the incentives, responsibility, and ownership for local authorities to improve service delivery. Crucially, for functions where the local authorities have had full responsibility, better service quality has resulted than in those areas in which there are overlapping responsibilities between the center and the local authorities.

Credit Flows, Fiscal Policy, and the External Deficit of Bosnia and Herzegovina
Description: This paper develops and estimates a model of the trade balance of Bosnia and Herzegovina. Credit flows and the fiscal stance are found to play a significant role in determining the trade balance. On this basis the paper discusses the trade-offs between monetary and fiscal policy settings needed to achieve a clear downward path for the large current account deficit of Bosnia and Herzegovina.

The Myth of Post-Reform Income Stagnation in Brazil
Description: This paper uses Engel curves to estimate real income growth in Brazil. The estimated per capita household real income growth in metropolitan areas during 1987-2002 is about 4½ percent per year, well above the "headline" growth of 1½ percent obtained by deflating nominal incomes by the CPI. This suggests a substantial CPI bias during that period, likely owing to one-off effects of trade liberalization and inflation stabilization. The estimated unmeasured gains are higher for poorer households, implying a marked reduction in "real" inequality. This finding challenges the conventional wisdom that post-reform real income growth in Brazil was low.

Currency Mismatches and Corporate Default Risk: Modeling, Measurement, and Surveillance Applications
Description: Currency mismatches in corporate balance sheets have been singled out as an important factor underlying the severity of recent financial crises. We propose several structural models for measuring default risk for firms with currency mismatches in their asset/liability structure. The proposed models can be adapted to different exchange rate regimes, are analytically tractable, and can be estimated using available equity price and balance sheet data. The paper provides a detailed explanation on how to calibrate the models and discusses two applications to financial surveillance: the measurement of systematic risk in the corporate sector and the estimation of prudential leverage ratios consistent with regulatory capital ratios in the banking sector.

Asian Equity Markets: Growth, Opportunities, and Challenges
Description: Asian equity markets have grown significantly in size since the early 1990s, driven by strong international investor inflows, growing regional financial integration, capital account liberalization, and structural improvements to markets. The development of equity markets provides a more diversified set of channels for financial intermediation to support growth, thus bolstering medium-term financial stability. At the same time, as highlighted by the May-June 2006 market corrections, the increasing role of stock markets potentially changes the nature of macroeconomic and financial stability risks, as well as the policy requirements for dealing with these risks.
