This paper aims to contribute to the international policy debate around profit shifting, tax avoidance and SSA’s revenue mobilization efforts in three ways. First, it examines the importance of mining, the role of multinational enterprises (MNEs), and mining revenue outcomes in SSA. Second, it assesses the magnitude of profit shifting in mining drawing on new macro level research, supplemented by case studies to illustrate the lived experience of tax avoidance in SSA mining. Third, the paper identifies tax policy reforms that could boost revenue mobilization in SSA.

Countries generally tax the forestry sector to achieve the twin objectives of revenue maximization and sustainability of logging levels. In an ideal world of perfect markets and information, auctions would be the best instrument to determine the price of extraction rights. However, a number of factors-including a lack of information on the forest resources under consideration, uncertainties as to the stability of property rights over time, and a lack of access to credit-have limited the use of auctions so far, particularly in low-income countries. To establish transparency of the forestry sector's financial flows, this paper discusses a radical simplification of Liberia's current timber tax structure, including a proposal to reduce the sector's current tax system to two instruments, an area tax and an export tax.

This paper provides an overview of diamond mining in sub-Saharan African countries, and explores the reasons for substantial differences in their tax rates and fiscal revenues from the sector, which mainly arise from differences in the incentives for smuggling. In a theoretical model, we show that optimal diamond tax rates increase with the degree of competition among diamond buyers, as well as with the corporate share of diamond production, which is confirmed by the data. We then discuss policies to increase revenue, including by enhancing mining productivity, stimulating the exploration of new areas, reducing barriers to entry, and attracting investment into value-adding downstream operations.

We develop a multicountry model in which governments aim at excessive spending in order to serve the narrow interests of the group in power. This puts pressure on the monetary authorities to extract seigniorage, and thus affects the incentives countries would have to participate in a monetary union. This feature, ignored by the monetary union literature for Europe, is potentially important in Africa. We calibrate the model to data for West Africa and use it to assess proposed ECOWAS monetary unions. We conclude that monetary union with Nigeria would not be in the interests of other ECOWAS countries, unless it were accompanied by effective discipline over Nigeria's fiscal policies.

Abstract

Written by Ved P. Gandhi, Liam P. Ebrill, George A. Mackenzie, Luis Mañas-Antón, Jitendra R. Modi, Somchai Richupan, Fernando Sanchez-Ugarte, and Parthasarathi Shome, this book contains 12 articles. It examines the relevance to developing countries of the tax policy recommendations of supply-side economists and attempts to delineate policy guidelines to ensure that fiscal management enhances rather than inhibits growth and efficiency in the wider economy.

Abstract

This study indentifies some of the taxation problems most frequently encountered by Fund member countries in sub-Saharan Africa and seeks solutions that may be useful to either the region as a whole or to groups of countries in the region.
