 Digital markets have become an important part of our lives and of the global economy. What has happened over the last 10 years or so is that we've seen the emergence of a few big platforms, the so-called GAFAM, Google, Amazon, Facebook, etc., who have emerged as gatekeepers to the digital economy. So these platforms offer great products that consumers love. But at the same time, they also exert some enormous influence on the content we consume, on the products we buy, etc. The situation represents a big challenge to competition authorities and regulators because we want to foster innovation. And for that, we need to reward the firms that offer successful products. But at the same time, we don't want these firms to exert too much of an influence on the market and to stifle innovation by potential entrants. What is important to understand is that these markets present some specific features such as network effects, economies of scale, the role of data, the importance of innovation, which require a specific economic analysis if we want to get the trade-offs right. The objective of the course is to equip you with a good understanding of the economic principles that govern digital markets and to allow you to identify the pro and anti-competitive practices. This will help you structure your arguments when working on a case involving digital platforms. The course will be taught by a team of TSE experts who have been at the forefront of the debates surrounding the regulation of digital platforms. We will also have some leading practitioners who will share their experience by discussing in-depth some important recent cases. The course will feature parallel sessions tailored to the background of the participants whether they are lawyers or economists. And we will also have some plenary sessions so as to foster interactions. You can find more information on our websites. We look forward to seeing you there.
