Optimal Taxation in the Forestry Sector in the Congo Basin: The Case of Gabon
Description: This paper reviews forestry reform in the Congo basin, focusing on Gabon. It argues that the key challenge for the Congo basin countries is to manage their forests in a sustainable manner. It presents the current situation of forestry taxation and forestry reform in Gabon. The paper analyzes optimal taxation in the forestry sector using a static model. The model works from the proposition that tax policy should be used exclusively for revenue purposes and resource preservation should be achieved mainly through legislation and enforcement. It argues that when prices are uncertain the best practice is to tax only profits.

Policy Challenges of Population Aging in Ireland
Description: The projected rise in age-related government spending as a share of GDP in Ireland over the next forty years is among the highest in the euro area. In the absence of reforms, public debt will increase to unsustainable levels. This paper uses the IMF's Global Fiscal Model to compare the macroeconomic effects of different fiscal strategies to accommodate the rise in age-related spending. The simulations suggest that adopting a package of measures, including an increase in the retirement age, broadening the tax base, and raising indirect taxes, would be a more growth-friendly strategy than relying exclusively on raising the social security contribution rate.

Benchmarking the Efficiency of Public Expenditure in the Russian Federation
Description: This paper benchmarks the efficiency of public expenditure in the social sectors in the Russian Federation relative to other countries and among the country's regions. It finds that there is substantial room for efficiency gains, particularly in health care and social protection, although less so in education. An econometric analysis of efficiency differences between the regions suggests that they are positively related to per capita income and the quality of governance and democratic control, while they are negatively related to the share of federal transfers in the respective region's government revenue and the level of spending relative to gross regional product.

Implications of Oil Inflows for Savings and Reserve Management in the Cemac
Description: This paper argues that as part of their fiscal optimization strategies CEMAC countries should be given the opportunity to invest into longer-term assets that generate market-based returns. The BEAC has created a framework of longer-term savings funds but due to low remuneration and other factors usage has remained limited. The paper also argues that regional savings in the form of reserve accumulation must be sufficient to ensure the stability of the common currency. While the current level of common foreign reserves may now be appropriate, maintaining an adequate level calls for a link between country-specific savings decisions and the setting of a regional reserve target. Strengthening and diversifying reserve management will also be desirable, a process the BEAC has embarked upon.

Alternative Fiscal Rules for Norway
Description: This paper considers long-term fiscal policy options in Norway, the world's fifth largest oil exporter, in light of the substantial expected increase in pension outlays. It compares the current fiscal rule, which targets a (central government structural) non-oil deficit equal to 4 percent of Government Pension Fund assets, with three alternatives that save a larger share of oil revenue and accumulate more assets to pay for aging costs. It also analyzes the macroeconomic consequences of accumulating more assets, finding that the additional income generated from more assets allows lower tax rates, with positive effects on long-term output.

How Does Financial Globalization Affect Risk Sharing? Patterns and Channels
Description: In theory, one of the main benefits of financial globalization is that it should allow for more efficient international risk sharing. This paper provides a comprehensive empirical evaluation of the patterns of risk sharing among different groups of countries and examines how international financial integration has affected the evolution of these patterns. Using a variety of empirical techniques, we conclude that there is at best a modest degree of international risk sharing, and certainly nowhere near the levels predicted by theory. In addition, only industrial countries have attained better risk sharing outcomes during the recent period of globalization. Developing countries have, by and large, been shut out of this benefit. The most interesting result is that even emerging market economies, which have experienced large increases in cross-border capital flows, have seen little change in their ability to share risk. We find that the composition of flows may help explain why emerging markets have not been able to realize this presumed benefit of financial globalization. In particular, our results suggest that portfolio debt, which has dominated the external liability stocks of most emerging markets until recently, is not conducive to risk sharing.

Sukuk vs. Eurobonds: Is There a Difference in Value-at-Risk?
Description: This paper assesses the impact of bonds issued according to Islamic principles (Sukuk), on the cost and risk structure of investment portfolios by using the Value-at-Risk (VaR) framework. The market for Sukuk has grown tremendously in recent years at about 45 percent a year. Sukuk provide sovereign governments and corporations with access to the huge and growing Islamic liquidity pool, in addition to the conventional investor base. The paper analyzes whether secondary market behavior of Eurobonds and Sukuk issued by the same issuer are significantly different to provide gains from diversification. The analysis, employing the delta-normal as well as Monte-Carlo simulation methods, implies such gains are present and in certain cases very significant.

Hedonic Imputation versus Time Dummy Hedonic Indexes
Description: Statistical offices try to match item models when measuring inflation between two periods. However, for product areas with a high turnover of differentiated models, the use of hedonic indexes is more appropriate since they include unmatched new and old models. There are two main competing approaches to hedonic indexes are hedonic imputation (HI) indexes and dummy time hedonic (HD) indexes. This study provides a formal analysis of exactly why the results from the two approaches may differ and discusses the issue of choice between these approaches. An illustrative study for desktop PCs is provided.

The Health Sector in the Slovak Republic: Efficiency and Reform
Description: The paper assesses the financial situation of the health sector in the Slovak Republic. It also evaluates the efficiency of health expenditures and service delivery in comparison to the OECD and other new EU member states and suggests avenues for cost recovery and reform. The health sector of the Slovak Republic is plagued by financial problems. To turn around health system finances and achieve larger gains in health outcomes, the efficiency of health spending needs to increase and the mix and quality of real health resources need to be improved. Although Slovak's overall health spending efficiency is on par with that of the OECD, substantial inefficiencies occur in the process of transforming intermediate health inputs into health outcomes. Efficiency may be enhanced by containing the cost of drugs and reducing reliance on hospital care. Also, although cost-effectiveness may be relatively high at present, its sustainability in the future is an issue.

Sri Lanka’s Sources of Growth
Description: This paper uses the growth accounting framework to assess Sri Lanka's sources of growth. It finds that while labor was the dominant factor contributing to growth in the 1980s, labor's contribution declined over time and was overtaken, to a large extent, by total factor productivity (TFP) and, to a lower extent, by physical and human capital accumulation. A higher growth path over the medium term will depend on securing a stable political and macroeconomic environment; implementing structural reforms necessary to improve productivity and efficiency of investment; attaining fiscal consolidation; and creating space for the private sector.
