 What TSE and Yale have in common is a really excellent research community and one that's quite focused on this area of competition. It's called Industrial Organization Economics and TSE is, I think, the best in Europe. TSE economists have been very, very much involved in competition policy and in helping design the framework of competition policy in the EU. Both have the same view of the way in which we should be thinking about economics which is we should mix very good theory with very good empirical work and a strong interest in using the research work done in economics in order to help regulators and to help design better regulation. It's somewhat under explored considering its importance and both of us were trying to get started on research in this area and we realized it would be more fun and more productive to do that together. The main aim of a workshop here was to get very much top researchers in the area of a digital economy to discuss together what should be the agenda. Perhaps what is even more important is a large interest in understanding how we can improve the functioning of the digital economy which is often concentrated around a few large firms to make them behave more competitively, to make them more valuable for society and to have them perform better for broad swaths of the population. Current policy in the regulation of digital platforms is quite different across the Atlantic. In Europe there is actually a new law. It has been voted and approved and it will take effect shortly and therefore there is some policy urgency for economists to be able to answer questions about how this law might be enforced, what impacts it might have on different business models, how it will affect competition. The policy environment in the United States is lagging behind by contrast in that there are laws that have been proposed but nothing that has progressed to a stage where it is likely to become a new law and those laws that have been proposed are less comprehensive than the Digital Markets Act and the Digital Services Act. We were very, very lucky to have two very good outside participants one from the European Commission who explained to us what were the challenges that the European Commission had in implementing the new regulations and one lawyer who works for Microsoft who tried to explain to us what did the regulation look like from the inside of the firm, what type of changes they had to make, how they thought about their compliance with the regulation and I think this is going to really inform the way in which people are doing research and the topics in which they are doing research on the digital economy. We have to monitor and learn and see what we've ignored and what we've overlooked and improved and for that workshops such as this are crucial. If you leave economists alone in their offices without community or some information about what is happening in the world then of course the work they are going to do will be less useful to society and this initiative not only will we be able to start building a community today but we hope to grow that community so that it becomes larger and more useful and more influential.
