Using a comparative framework, this volume presents case studies of issues of public procurement and discusses how procurement professionals and policy makers in different regions are responding to these challenges. This book discusses current issues in public procurement. Over the past few decades, public procurement has had to evolve conceptually and organizationally in the face of unrelenting budget constraints, government downsizing, public demand for increased transparency in public procurement, as well as greater concerns about efficiency, fairness and equity. Procurement professionals have also had to deal with a changeable climate produced by emerging technology, environmental concerns, and ongoing tension between complex regional trade agreements and national socioeconomic goals. The first section discusses innovation and reforms in public procurement and how practitioners are adapting to and making use of new technologies. The second section addresses the challenges of maintaining transparency, equity, and fairness in public procurement. The final section discusses preferential public procurement and introduces strategies for building sustainable public procurement systems. By combining theory and analysis with evidence from the real world, this book is of equal use to academics, policy makers, and procurement professionals.
