This course offers an in-depth exploration of the economic principles in the digital era. As digital technologies and online platforms increasingly influence global markets, understanding their implications becomes essential for future economists. We will examine critical topics, including digital platforms, data regulation, search algorithms, and their effects on consumer behaviours and market structures. Through a combination of theoretical frameworks and practical case studies, students will develop a comprehensive understanding of how digital technologies and platforms shape economic interactions and regulatory challenges. By the end of the course, students will be equipped with the analytical tools necessary to critically assess the role of digital technologies in contemporary economic contexts.
