This book is a major stocktaking of law and economics in the context of developing and emerging economies, and in the light of the dramatic changes in the global economy that we have witnessed in recent years. The rise of artificial intelligence, digital technology, and mega platforms that collect data and facilitate trade is changing the landscape of economics. Rapid globalization has created new challenges for law and regulation, since increasingly contentious cases arise which span multiple countries and several legal jurisdictions. All these changes are giving rise to new problems in developing countries where many people lead precarious lives anyway, healthcare is minimal, and corruption widespread. Alongside these global developments, the discipline of law and economics is also undergoing profound changes, making us re-think some of the founding assumptions of the subject.
