Biography
Souleymane Coulibaly, from Cote d'Ivoire, holds a double Ph.D. degree in International Trade and Economic Geography from the University of Paris 1 Pantheon-Sorbonne (France) and the University of Lausanne (Switzerland). His publications and ongoing research deal with the impact of geography on firms’ location, trade flows and regional integration. He was a co-author of 2009 World Development Report "Reshaping Economic Geography", contributed to the 2005 Global Economic Prospect report on regionalism, and recently published the book “Eurasian Cities: New Realities along the Silk Road” in the ECA regional studies series. He is the Program Leader and Lead Economist for Central Africa. He joined the World Bank Africa Region in January 2014 from the Operation and Policy and Quality Unit (OPCS) where he was covering Development Policy Lending and Guarantee policies and operations, and represented the unit in the Non-Concessional Borrowing Policy committee. Before OPCS, he was in the Eastern and Central Asia (ECA) region working simultaneously as trade economist and country economist of some former Soviet countries (Armenia, Kazakhstan, Kyrgyzstan and Tajikistan), as well as ECA regional trade coordinator. Before joining the World Bank as a Young Professional in September 2006, he used to be lecturer at the Ecole Nationale Superieure de Statistiques et d’Economie Appliquée (ENSEA) of Abidjan, teaching assistant at the University of Lausanne, and economist at the Economic and International Relations department of NESTLE in Vevey, Switzerland.

Solow in Transition : Macro and Micro Determinants of Savings in Armenia
(World Bank, Washington, DC, 2013-07)This paper analyzes and reconciles macro and micro evidence on savings and factors that affect savings, as well as possible policy implications. At the aggregate level, the main question is how savings are affected by growth and macroeconomic policies and variables (fiscal policy, exchange rate, for example) and the breadth of financial markets. Some of these macro determinants can be reconciled with microeconomic evidence of the savings behavior of households. Using macroeconomic quarterly data and household survey data, the analysis explores the determinants of the savings rate at the macroeconomic and microeconomic levels, using the typical econometric models used in the literature (long-term co-integration relation and short-term error correction model for the macro determinants; linear multivariate models for the micro determinants). The long-term relationship indicates that a 10-percent increase in gross domestic product per capita would add 3.7 percentage points to the savings rate in the long run. The short-term relationship depicts a strong catch-up process to the long-run equilibrium, with quarterly changes in gross domestic product per capita and openness strongly correlated with quarterly changes in the savings rate. The characteristics of households that represent the volatility of expected income, such as education and access to borrowing or remittances, significantly impact saving rates. The macroeconomic and microeconomic analyses of the determinants of saving rates in Armenia point to three policy areas: the macroeconomic environment, the financial sector, and the role of remittances. -

Fiscal Consolidation and Recovery in Armenia
(World Bank, Washington, DC, 2012-02)Armenia's strong economic growth from 2001-2008, when real gross domestic product (GDP) grew 12.6 percent per year on average, boosted living standards and created the fiscal headroom necessary for the Government to respond to the 2009 financial crisis with a large fiscal stimulus. As a result, the fiscal deficit reached 7.6 percent in 2009 and helped limit the contraction in real GDP to 14 percent. With the economy growing again, the stimulus has to be gradually withdrawn. However, the retrenchment will need to be designed carefully to limit negative impact on growth. Improving the efficiency of all aspects of public finances - tax policy, tax administration, and public expenditures - will be crucial to the planned fiscal adjustment. With the ratio of tax revenues to GDP lower than that of comparator countries with similar levels of income per capita, the brunt of the fiscal consolidation should be borne by an increase in tax revenues (the lower bound estimated to be between 2.3 and 5.8 percent of GDP).
