This paper assesses São Tomé and Príncipe's monetary and exchange rate arrangements in light of the country's monetary history and the relevant experience of comparable countries in Africa. The study highlights several structural characteristics of São Tomé and Príncipe including its very small size, high degree of openness, extensive use of foreign currencies, and inflexible product and factor markets in the consideration of an appropriate monetary and exchange regime. Firmly anchored currency arrangements, defined in this paper to include memberships in monetary unions or hard pegs, are found to be preferable to the status quo of a managed float. The paper applies statistical methods and takes into account other factors to identify the appropriate anchor currency. It stresses that fiscal discipline and prudent debt management are the main prerequisites for a firmly anchored currency arrangement.

What role does China play in Africa's development? What drives China's increasing economic involvement in the continent? This paper attempts to provide a quantified assessment of China's multifaceted influence as market, donor, financer and investor, and contractor and builder. Though in the past official development aid predominated, the paper argues that government policies, markets for each other's exports, Africa's demand for infrastructure, and differences in China's approach to financing have together moved commercial activities-trade and investment-to the center of China-Africa economic relations. While China's public sector, state financial institutions in particular, has been instrumental in the process, the influence of its private sector is increasing. Implications for the future of China-Africa economic relations are briefly noted.

This study assesses the experience of the Common Monetary Area (CMA) based on available empirical evidence over the last two decades. It pays particular attention to member countries' adjustment to economic shocks in recent years and the inter-country linkages, including the spillover effects of policies. The paper draws the main lessons from the CMA experience, identifies key policy challenges, and discusses the issues facing the member countries in their efforts to achieve sustained growth. Implications for further economic integration in a broader regional context are also noted.
