Effect of Corruption on Tax Revenues in the Middle East
Description: This study estimates the impact of corruption on the revenue-generating capacity of different tax categories in the Middle East. We find that the low revenue collection as a share of GDP there compared to other middle-income regions is due in part to corruption, and certain taxes are more affected than others. Taxes that require frequent interaction between the tax authority and individuals, such as taxes on international trade, seem to be more affected by corruption than most other types of taxation. This suggests that if governments need to raise more tax revenues in a way that minimizes distortions and maximizes social welfare, they should implement reforms that either reduce corruption or raise revenues from tax categories that are less susceptible to corruption. Possible reforms of the revenue system and administration are examined.

What Explains India’s Real Appreciation?
Description: We examine the evolution of nontradable and tradable prices in the Indian economy over 1980-2002 and find widening differentials: the real exchange rate has been appreciating. This might seem unsurprising, since India's rapid per capita income growth suggests Balassa-Samuelson factors at play. However, after 1990, the tradable-nontradable labor productivity gap, the driver of real appreciation according to Balassa-Samuelson, virtually disappeared. So what explains the real appreciation? Assessing the role of both demand and supply factors, we find that demand pressures arising from higher income growth accounted for much of the relative price increase during the post-reform period. Falling import prices also contributed significantly, along with an increase in government spending.

Estimating Spillover Risk Among Large EU Banks
Description: The paper examines the scope for cross-border spillovers among major EU banks using information contained in the stock prices and financial statements of these banks. The results suggest that spillovers within domestic banking systems generally remain more likely, but the number of significant cross-border links is already larger than the number of significant links among domestic banks, adding a piece of empirical evidence supporting the need for strong cross-border supervisory cooperation within the EU.

China’s Changing Trade Elasticities
Description: China's sectoral trade composition, product quality mix, and import content of processing exports have all changed substantially during the past decade. This has rendered trade elasticities estimated using aggregate data highly unstable, with more recent data pointing to significantly higher demand and price elasticities. Sectoral differences in these parameters are also very wide. All this suggests greater caution in using historical data to simulate the response of the China's economy to external shocks and exchange rate changes. Analyses based on models whose estimated coefficients largely reflect the China of the 1980s and 1990s are likely to turn out to be wrong, perhaps even dramatically.

The Use of Encompassing Tests for Forecast Combinations
Description: The paper proposes an algorithm that uses forecast encompassing tests for combining forecasts. The algorithm excludes a forecast from the combination if it is encompassed by another forecast. To assess the usefulness of this approach, an extensive empirical analysis is undertaken using a U.S. macroecoomic data set. The results are encouraging as the algorithm forecasts outperform benchmark model forecasts, in a mean square error (MSE) sense, in a majority of cases.

Education and Health in G7 Countries: Achieving Better Outcomes with Less Spending
Description: Enhancing the efficiency of education and health spending is a key policy challenge in G7 countries. The paper assesses this efficiency and seeks to establish a link between differences in efficiency across countries and policy and institutional factors. The findings suggest that reforms aimed at increasing efficiency need to take into account the nature and causes of inefficiencies. Inefficiencies in G7 countries mostly reflect lack of cost effectiveness in acquiring real resources, such as teachers and pharmaceuticals. We also find that high wage spending is associated with lower efficiency. In addition, lowering student-teacher ratios is associated with reduced efficiency in the education sector, while immunizations and doctors' consultations coincide with higher efficiency in the health sector. Greater autonomy for schools seems to raise efficiency in secondary education.

Effect of IMF Structural Adjustment Programs on Expectations: The Case of Transition Economies
Description: We analyze the effect of IMF programs on economic agents' expectations about the economy in transitional countries using survey data from the Central and Eastern Eurobarometer poll, an annual general public survey monitoring the evolution of public opinion from 1990 to 1997. Previous studies, in contrast, have looked at indirect measures, such as capital flows or yield spreads, to assess the impact of IMF programs on economic expectations. Using a multinomial probit model, we find that IMF loans appear to have a strong effect on agent expectations in the early years, through the inflow of real money, and through the signaling effect. IMF programs during periods of collapsing growth appear to reinforce underlying expectations for the future; they are associated with positive expectations for those with an optimistic outlook and negative expectations for those with a negative outlook. Once recovery is underway, and economic uncertainty diminishes, it appears that IMF programs cease to have a statistically significant effect on the expectations of economic agents. This suggests that IMF programs have the biggest impact on expectations during periods of great uncertainty and less of an impact when countries are subject to minor shocks.

The Duration of Capital Account Crises—An Empirical Analysis
Description: This paper examines the duration of capital account crises. We develop a new index to identify both the start and the end of these crises. Applying the index to a sample of 18 crisis episodes, we derive stylized facts on crisis duration and review the economic and financial circumstances that prevailed at the dusk of crises, a relatively unexplored area. We use the econometric technique of duration analysis to gauge the relative importance of various factors affecting the probability of exiting a crisis. We find that initial and external conditions are key determinants. But fiscal and monetary policies can also help shorten crisis duration.

Consistent Quantitative Operational Risk Measurement and Regulation: Challenges of Model Specification, Data Collection and Loss Reporting
Description: Amid increased size and complexity of the banking industry, operational risk has a greater potential to transpire in more harmful ways than many other sources of risk. This paper provides a succinct overview of the current regulatory framework of operational risk under the New Basel Capital Accord with a view to inform a critical debate about the influence of varying loss profiles and different methods of data collection, loss reporting, and model specification on the reliability of operational risk estimates and the consistency of risk-sensitive capital rules. The presented findings offer guidance on enhanced market practice and more effective prudential standards for operational risk measurement.

Capital Account Convertibility and Risk Management in India
Description: This paper takes a closer look at the prudential and regulatory measures needed to prepare India's financial system to manage the risks arising from fuller capital account convertibility (FCAC). The paper contributes to the debate on FCAC in two ways. First, it reviews the potential and existing financial stability challenges to FCAC in India. Second it studies how prudential regulation and supervision is addressing these challenges. The main conclusion is that regulatory and supervisory measures alone are not enough and will need to be complemented by improvements in Indian banks' risk management and further development of the domestic capital markets.
