Market entry into Africa: Acquisitions and international joint ventures. Studies of foreign firms' market entry strategies, challenges, and performance in Africa INTRODUCTION

While the interest in investing in Africa is rising, the know-how of business on the continent is very limited. There have been only recently few special issues focusing on sub-Saharan Africa in the top international business journals: "Sub-Saharan Africa at a key inflection point" (Thunderbird International Business Review 2009); "Contemporary developments in the management of human resources in Africa" (Journal of World Business 2011); "Contemporary challenges and opportunities of doing business in Africa" (Journal of Technological Forecasting and Social Change 2016); "Critical perspectives on international business in Africa (Critical Perspectives on International Business 2016); "Strategic Management in Africa (Global Strategy Journal, 2017); and "The internationalization of African firms (Thunderbird International Business Review 2016). The aim of this special issue is to advance understanding of international business in Africa and specifically focus on how foreign firms enter African markets via acquisitions and international joint ventures and extend knowledge of these market entry strategies and performance in Africa for research and for foreign firms intending to, or currently doing business in Africa. This guest editorial provides a summary of the five articles and one book review in this special issue categorized into three broad thematic issues: International joint ventures and acquisitions as market entry strategies in Africa; cross-border investments of African firms; and theoretical underpinnings.
