 Please join me in welcoming Greg Nelson. Hey everybody, thanks for welcoming me back to the Bay Area, the chance to live both in San Francisco and in Oakland for about five years before moving to the muggy confines of D.C. back in 2008-2009 and I realize it had been about almost a year, more than a year since I had had the chance to come back so I appreciate that and I appreciate you guys welcoming me with 100-degree muggy weather which is exactly I was trying to get away from. So I want to give a big thanks to peers and to SOCAP for pulling this all together. It's pretty exciting for us to be part of it. I'm really here today to learn, to get a chance to hear from you all as you're grappling with a lot of these difficult challenges in a growing area, a place where innovation is happening, both at the company level but also frankly at the policy level. I want to hear a little more about that today. Why is the White House here? Why are we engaged? I think there's a couple of reasons. The most important is, those of you have probably seen in the last couple of years, the President spent quite a bit of time talking about sharing. He talks about it in the shared prosperity, shared opportunity and shared responsibility. That was the theme of the 2012 campaign. It's been a theme of this administration and how can we make sure that we are breaking down barriers and providing opportunity for citizens, for all of you here and throughout the world to build a better community that's going to enable and embody those kinds of values. I think there's real, real opportunities in what you're doing and real opportunities in how it's starting to remake the map in cities across the globe. As David mentioned, these innovations bring up challenges and questions that it sounds like you really tackled and struggled with yesterday around access, around equity, around how do we ensure that this is a kind of an opportunity that everybody can participate in and that, frankly, that the policy world can keep up with the innovations that you guys are creating. That's something that, in D.C., we try to make sure that we are thinking through what's happening out here, trying to catch up with everything that is going on, but ensuring that your world is what's driving it, driving down the cost of consumer interactions, driving down, enabling opportunities for consumer choice and resisting the chance to add more friction into a system and new markets that are providing consumers and retailers and supporters with additional opportunity. We want to make sure we learn a lot more about what's happening before we go out and think about what our role is going to be. We've already had some instances where it's come up, even as regulation has not been coming from the federal side. Two examples of that are when Hurricane Sandy hit in the northeast, the Federal Emergency Management Administration, FEMA, gives out housing vouchers to help make sure everybody who lost a home in a natural disaster gets a chance to find another location and place to stay, whether it's a hotel, an apartment building, whatever they can do, and Airbnb stepped up and actually every member stepped up and started offering their homes. So FEMA wasn't something they'd ever confronted before. This is a significant major national disaster and an opportunity where the sharing community really stepped up and provided housing for these individuals who lost their homes. And we were able to work with FEMA to allow those housing vouchers to be used in Airbnb facilities, which was an exciting and new innovation for where we've gone. That's the kind of thing that I think we're going to see a lot more of. On my way over here this morning, a question came up thinking about procurement, federal procurement. Should I have the ability, when I'm spending some of the trillion dollars of federal procurement by catching a ride over here, should that be reimbursable? Should IT procurement be something that sharing, sorry, federal procurement broadly be something that the sharing economy companies can participate in and can they be part of the federal spend? So all kinds of questions that we're going to have to grapple with. My main point for today is I really appreciate you guys are doing this. This is a huge set of issues to try to get ahead of and I'm glad to be here and participate and learn from you. I think the opportunity here is to spend as much time thinking about the questions of access, equity, opportunity, and prosperity now on the front end of this happening so that we can have as much innovation in policymaking and innovation in the way that we interact with continuing to help you all open markets on the front end rather than all on the back end. So that's why we're here. I'm leading a project now that will try to help look at some of this from the perspective of the federal side and the White House and I'm excited to learn from you all and participate today. So thanks for having me and keep it going.
