How to Crack a Nut is a blog published by Professor Albert Sanchez-Graells that explores issues at the intersection of public procurement, digital transformation, and regulatory frameworks. The blog discusses the role of procurement as a form of infrastructure shaping state capacity and governance, with attention to legal, economic, and administrative perspectives. It also covers emerging challenges in AI procurement and deployment, including human rights considerations, regulatory developments such as the EU AI Act, and public sector governance of generative AI tools. The blog reflects on academic and policy debates around procurement systems, AI ethics, and the implications of technological adoption in public administration.
