How does governance shape economic growth, trade openness, and investment across different regions and income groups? This book delves into the intricate relationship between governance and economic performance, offering empirical insights through case studies and rigorous analyses. From the economic trajectories of African nations to the business environments of the Visegrád and Maghreb countries, this collection of research explores the impact of governance on trade, foreign direct investment, and financial stability. It also examines Tunisia's economic and social challenges, including the repercussions of COVID-19 and the evolving relationship with the European Union under the Deep and Comprehensive Free Trade Agreement (DCFTA). Drawing from advanced econometric techniques, including Granger causality tests, and real-world policy implications, this book is an essential resource for policymakers, economists, and scholars seeking to understand governance's pivotal role in global economic structures.
