Contributor(s): Professor Edward Glaeser | Building and maintaining cities is difficult and density has costs, but in this presentation Professor Edward Glaeser will argue that these costs are worth bearing, because whether in London’s ornate arcades or Rio’s fractious favelas, whether in the high rises of Hong Kong or the dusty workplaces of Dharavi, our culture, our prosperity, and our freedom are all ultimately gifts of people living, working, and thinking together – the ultimate triumph of the city. Edward Glaeser is the Fred and Eleanor Glimp Professor of Economics at Harvard. He is widely regarded as one of the world’s most exciting urban thinkers. Travelling from city to city, speaking to planners and politicians across the globe, he uncovers questions large and small whose answers are deeply significant. His new book, Triumph of the City, is available on 18th March 2011.
