Personal income taxes (PITs) play little or no role in the Middle East and North Africa, often yielding less than 2 percent of GDP in revenue—with the exception of few North African countries. This paper examines how PITs have evolved in recent decades, and what they might look like in the next 20 years. Top marginal tax rates on labor and business income of individuals have declined substantially, a trend that mirrors reductions in advanced and developing economies. Taxation of passive capital income has changed very little, and the revenue intake from this source remains low throughout the region (less than 1 percent of GDP on average and concentrated in oil-importing non-fragile states). Social security contributions (SSC) have increased in importance in nearly all MENA countries, and some countries have introduced additional payroll taxes. The combination of reduced marginal tax rates, light taxation of income from capital and business activities, and increase of SSC, have resulted in income tax systems that create disincentives to work and incentives for informality, and contribute little to government revenue and income redistribution. Given differences in economic and political structures, demographics, and starting points, the path to PIT/SSC reforms will vary across the region. Countries with relatively mature PIT/SSC systems, where revenue performance has improved in the past two decades, will increasingly need to balance the revenue and equity objectives against effciency objectives (in particular labor market incentives and infromality). Countries with no PITs will have to weigh whether a consumption tax/SSC system that mimic a flat tax on labor income is sufficient to diversify revenue away from oil and whether to adopt PITs to address rising income and wealth inequality. Finally, fragile states, who face more political volatility and weaker fiscal institutions, will have to focus on simplicity of tax design and collection to be able to raise revenue from PITs.

There is a growing debate on the relative merits of universal and targeted social assistance transfers in achieving income redistribution objectives. While the benefits of targeting are clear, i.e., a larger poverty impact for a given transfer budget or lower fiscal cost for a given poverty impact, in practice targeting also comes with various costs, including incentive, administrative, social and political costs. The appropriate balance between targeted and universal transfers will therefore depend on how countries decide to trade-off these costs and benefits as well as on the potential for redistribution through taxes. This paper discusses the trade-offs that arise in different country contexts and the potential for strengthening fiscal redistribution in advanced and developing countries, including through expanding transfer coverage and progressive tax financing.

Financially closed economies insure themselves against current-account shocks using international reserves. We characterize the optimal management of reserves using an open-economy model of precautionary savings and emphasize several results. First, the welfare-based opportunity cost of reserves differs from the measures often used by practitioners. Second, under plausible calibrations the model is consistent with the rule of thumb that reserves should be close to three months of imports. Third, simple linear rules can capture most of the welfare gains from optimal reserve management. Fourth, policymakers should place more emphasis on how to use reserves in response to shocks than on the reserve target itself.

This paper presents stylized facts on the quantitative and qualitative infrastructure gap in the West African Economic and Monetary Union (WAEMU), estimates the efficiency of public investment, and recommends how to improve it. The WAEMU countries face an important common challenge of creating sufficient fiscal space to finance ambitious growth, development, and poverty-reduction programs in individual countries. This paper also provides comparative evidence of the situation of WAEMU in several areas of financial development relative to groups of benchmark countries. The state of inclusion in the WAEMU along three dimensions—poverty, income inequality, and gender inequality—is also examined in this paper.

This paper tests the theoretical framework developed by North, Wallis and Weingast (2009) on the transition from closed to open access societies. They posit that societies need to go through three doorsteps: (i) the establishment of rule of law among elites; (ii) the adoption of perpetually existing organizations; and (iii) the political control of the military. We identify indicators reflecting these doorsteps and graphically test the correlation between them and a set of political and economic variables. Finally, through Identification through Heteroskedasticity we test these relationships econometrically. The paper broadly confirms the logic behind the doorsteps as necessary steps in the transition to open access societies. The doorsteps influence economic and political processes, as well as each other, with varying intensity. We also identify income inequality as a potentially important force leading to social change.

The Poverty Reduction Strategy Paper, whose implementation has now reached the second year, has been the key instrument in Mauritania's economic, social, and institutional development policy. The pursuit of policies to accelerate growth, maintain macroeconomic stability, and enhance the competitiveness of the economy have thus made it possible to attain an economic growth rate of about 3.3 percent notwithstanding an unfavorable international economic climate. Annual inflation has been contained at 4 percent.

In preparation for the 2003 IMF-World Bank spring meetings, the IMF Executive Board will review progress on the IMF’s efforts and plans to help poor countries further. The IMF Survey talked to Masood Ahmed, Deputy Director of the IMF’s Policy Development and Review Department, about this effort.
