 colleagues and deputy governor, first I'd like to thank everybody here, politicians, academics, non-governmental organization, activists, business people, on behalf of my colleagues from the London School of Economics and other universities for giving us such a wonderful time here in Sao Paulo and indeed the other cities that are represented from Brazil and beyond in Latin America. We've had a great time and it's been for me anyway a profoundly important opportunity to learn. I think the key themes that we've had discussed here in Sao Paulo have built from earlier urban age themes that have taken place in other conferences but with a key difference again and again we've come back to in different ways the extent to which changes in the global economy will now have a global to local effect. Saskia Sassan and I were at a conference in New York before we came here and the same kind of issues came up strongly there to this global to local link. There is less certainty that the future will be the same as the past. I think Sao Paulo has provided an excellent backdrop for us building on the very different things we've picked up from other urban age cities but with many similarities as well. So the kind of issues we've picked up in the last two days include the fact that urban agglomerations continue to evolve, they are radical, they are exciting, they make our lives. Certainly everybody in this room finds them exciting and interesting and there's no let up in the excitement that these epic scale places can provide. There's been a debate about changing influences on cities and on their people. The economic slowdown I've mentioned, the impact of global problems and the flow of capital which we've come up against again this afternoon and the evolution of the management of risk and on the subject of this fascinating issue and I'm here now so I can say this, I was going to say it earlier. The issue we bumped into this afternoon about the way in which capital no longer available at the national global level will it be available locally. I think it's worth remembering that in many older cities it used to be available locally as was Saskia said and what's happened is that because upper levels of government wanted more tax for consumption which is popular, they've left local governments struggling, unable to raise their own resources to invest in themselves and I think there is a big issue there that the urban age might wish to come back to. We've touched on transport as the urban age often does, it's a major and important issue which everybody can understand in this city, in all cities we need to get about to bring people into the labour market to allow us all to travel around in a way that doesn't destroy the environment but which does make it possible for us to visit people and to mix in the way that Charles Correa was saying this afternoon and we've heard about the power of leadership and the need for government. What we've heard less about till this afternoon is this question of money, my own home topic actually, I think the extent to which cities are massive movers of money and resources and the fact that you can use public finance to redistribute money around cities either using government machinery or using equalization mechanisms is another one that we might want to pick up in future conferences. We've heard a bit less here about heritage and culture than in the past and rather a lot less about financial and business services except as a problem. So to summarise, there's clearly no letter, no letter in the need to analyse cities. Everybody in this room does it either privately as they walk around the street or professionally all the time. But there is a need I think to move beyond the talk that we've done here and to come up with ideas that we can transfer very effectively from one city to another. Sao Paulo and other Latin American cities have I think extraordinary opportunities in their particular current stage of development to learn from the mistakes that have been made elsewhere. We can certainly learn things from Latin America. I've learned a lot about buses from Latin America I can tell you that. The urban age itself has been enriched by Sao Paulo and we can now move on to Istanbul next year so I'd like to thank you all on behalf of the LSE and I'd like to help the hair house and society as well. Wolfgang Novak who's our great friend and all the others who helped make this such a wonderful event. So thank you very much.
