Abstract
<jats:p>The transformation of the global economic order marks an era of increasing uncertainty, a redefinition of power balances, and a revolutionary role for technology in public administration. Uncertainties in trade policies, rising geopolitical tensions, volatility in energy markets, the rise of the digital economy, and the transformation wrought by artificial intelligence technologies across all sectors, including the public sphere, have made economic decision-making processes more complex than ever. This book aims to present a comprehensive analysis at the intersection of various disciplines, bringing together the economic, technological, and institutional dimensions of these transformations. The first chapter examines the interactions between trade policy uncertainty, geopolitical risks, and the energy market. In particular, the impact of energy price volatility on global risk appetite and policymakers' strategic choices is evaluated in light of both historical and current developments. A key area of discussion is how geopolitical risks shape energy supply security and the role of trade policies on global value chains. Completing this framework, the second chapter examines in detail the impact of the trade war between the United States and China on commodity markets. The pressures this economic competition exerts on a wide range of price mechanisms, from metals and agricultural products to energy commodities, are evaluated within the context of the restructuring of global supply chains. This demonstrates that trade wars are not simply a conflict between two countries, but rather a reflection of a much broader global economic transformation. The third and fourth chapters, which examine the impact of technological transformation on urbanization and public investments, are closely interconnected. The success factors of smart city public-private partnership projects are examined from a multidimensional perspective, from institutional capacity and financing models to technological infrastructure and stakeholder management. Furthermore, the role of artificial intelligence in public-private partnerships is discussed in detail. The opportunities offered by artificial intelligence in decision support processes, risk management, maintenance optimization, and increased project efficiency are considered a new paradigm for modern public administration. Another chapter of the book focuses on digital currencies, central banks, and monetary policy, one of the most critical topics in the digital economy. The potential impact of central bank digital currencies (CBDCs) on financial stability, the monetary policy transmission mechanism, and the banking system is evaluated using both a theoretical framework and international practices. This discussion encompasses a broad analysis of digitalization, encompassing aspects of financial sovereignty, competition, and regulation. The US Federal Reserve (FED), which has been at the center of the global financial architecture since the beginning of the twentieth century, has become not only a national institution but also a decisive actor in the international economic-political order, thanks to its capacity to manage crises, its diversification of monetary policy instruments, and its power to shape global liquidity cycles. The first part of the book examines the FED's historical journey, the evolution of its policy regimes, and the spillover effects of these policies on developing countries, revealing how the global power architecture has transformed. The final chapter of the book examines the financial performance of the banking and technology sectors, two of the most rapidly transforming sectors of our time, from a comparative perspective. This chapter demonstrates that sectoral change implies not only economic but also structural and managerial transformations. This book aims to comprehensively address the multidimensional dynamics shaping the global economy. Written from an interdisciplinary perspective, it aims to provide a comprehensive reference source for academics, practitioners, policymakers, and all readers interested in global economic developments. We would like to thank all the researchers who contributed to the creation of this work and everyone who supported it throughout the process. We hope that this study will make valuable contributions to the economics literature and decision-making processes in related fields.</jats:p>
