Default, Credit Growth, and Asset Prices
Description: This paper uses a Merton-type estimate of the probability of default (PoD) for the main banks in a sample of Organization for Economic Cooperation and Development and middle-income countries as a proxy for the fragility of their banking systems. Based on theory and stylized facts, the paper explores a range of financial and real variables that explain such PoDs across time. We find property price fluctuations and bank credit to be important explanatory factors. There is two-way interaction between these variables and a clearer relationship when the variables are entered as a deviation from trend. The lag structure between such developments and PoDs is long and varies widely across countries. The paper assesses the implications of these findings for economic policy.

The Incidence and Effectiveness of Prior Actions in IMF-supported Programs
Description: Prior actions are measures that need to be implemented prior to Board approval of an IMFsupported program. This paper examines whether such prior actions can signal a willingness to implement reforms, especially when the member's track record is weak. We find some support for this signaling role, particularly for programs supported by the General Resources Account (GRA). Controlling for the member's previous track record, prior actions are associated with greater compliance with other structural conditions, suggesting their possible use as a screening device. Moreover, prior actions set at program approval serve as a useful screening device and strengthen the macroeconomic targets set out in the IMF-supported program. The results also reveal a demonstrable screening effect on growth over the medium term, since the growth impact of the ratio of prior actions at the outset versus the rest of the program is significantly positive while the total number of prior actions is not statistically significant.

Political Instability and Inflation Volatility
Description: The purpose of this paper is to empirically determine the causes of worldwide diversity of inflation volatility. We show that higher degrees of political instability, ideological polarization, and political fragmentation are associated with higher inflation volatility.

The Monetary Policy Regime and Banking Spreads in Barbados
Description: The paper analyzes the determinants of banking spreads in Barbados, with a view to identifying the role of the monetary policy regime in explaining high spreads. The paper finds that interest rate spreads for Barbados are higher than would be suggested by its macroeconomic performance. Banking concentration and bank-specific variables, including bank size and provisions for nonperforming loans, do not have an important role in explaining variations in bank spreads. Rather, it appears that monetary policy variables, such as reserve requirements and capital controls, are the most important determinants of spreads.

Measuring Competitiveness
Description: This paper reviews alternative approaches to measuring an economy's cost competitiveness and proposes some new measures inspired by the economic theory of index numbers. The indices provide a theoretical benchmark for estimated real effective exchange rates, but differ from standard measures in that they are based on marginal rather than average sectoral shares in GDP or employment. The use of the new indices is illustrated by some simple calculations that highlight the potential exposure of the Irish economy to fluctuations in the euro-sterling exchange rate.

Economic Growth and Total Factor Productivity in Niger
Description: This paper investigates empirically the sources of aggregate output growth and the determinants of total factor productivity (TFP) in Niger between 1963 and 2003. A growth accounting analysis indicates that the erosion in output per capita over the sample period is due to the negative growth of both TFP and physical capital per capita. Sound macroeconomic policies, supported by official development assistance and structural reforms, are found to be key to raising TFP growth.

Money Market Integration
Description: We use transaction-level data and detailed modeling of the high-frequency behavior of federal funds and Eurodollar yield spreads to provide evidence of strong integration between the federal funds and Eurodollar markets, the two core components of the dollar money market. Our results contrast with previous evidence of segmentation of these two markets, showing them to be well integrated even at high intra-day frequency. We document several patterns in the behavior of federal funds and Eurodollar spreads, including liquidity effects from trading volume to yield spreads volatility. Our analysis supports the view that targeting federal funds rates alone is sufficient to stabilize rates in the, much larger, dollar money market as a whole.

Common Volatility Trends in the Central and Eastern European Currencies and the Euro
Description: How much convergence has been achieved between Central and Eastern European (CEE) economies and the eurozone? We explore this question by comparing long-run volatility trends in CEE currencies and the euro. We find that these trends are closely correlated, pointing to convergence in the economic and financial structures of these economies. Nonetheless, the degree of commonality remains weaker than what had been found for major European currencies before the introduction of the euro. Spillovers of volatility across regional markets appear to have diminished over time, with the exception of the Hungarian forint, which remains a source of volatility shocks to regional currencies.

A Principal-Agent Theory Approach to Public Expenditure Management Systems in Developing Countries
Description: A well-functioning public expenditure management (PEM) system is considered a critical pillar of government efficiency, on par with a low-distortion tax system and efficient tax administration. The paper discusses PEM systems in developing countries using an analytical framework based on principal-agent theory. This simple model can be applied to various PEM systems, and allows for comparisons between institutional settings. To illustrate this, we analyze the benefits derived from the use by the Ministry of Finance (MoF) of two control instruments; ex post audits and ex ante controls, and assess their value in terms of their ability to deter cheating. We derive a set of possible "control regimes" which can be used by the MoF. Although we illustrate the use of the model using developing countries, it is also relevant to developed economies.

Fiscal Implications of Multilateral Tariff Cuts
Description: The paper contributes to the discussion about the revenue implications of trade reform by assessing the approximate fiscal revenue impact of different liberalization formulae under consideration in multilateral trade negotiations for a group of low- and middle-income countries. The study applies a linear optimization framework to data for bound tariffs, applied tariffs, and imports at the HS-6 digit level for 58 developing countries, and simulates results for different sets of import demand elasticities and developing country "flexibilities." While only a small number of countries face a significant impact, results point toward the need for complementary fiscal measures in the countries most affected by revenue loss.
