Acknowledgments

This research was funded under Economic and Social Research Council Collaborative Award for Science and Engineering (ESRC CASE) Studentship PTA-033-2003-00008 with the Greater London Authority Economics Unit kindly acting as co-sponsor. My research was made possible through the input and direction of many individuals.

I would first like to extend my sincere appreciation to Professors Mike Batty and Paul Longley for their supervision, guidance and support throughout my time at UCL which I am truly grateful. Secondly to Margarethe Theseira and Bridget Rosewell for providing me with insights into the London economy and how such a city operates.

Thirdly, I would like to acknowledge the help and support to all the people of CASA, both past and present for providing such a stimulating working environment and friendships over the last four years. Without which this research would not be what it is. I would like to make specific acknowledgements to Christian Castle, Kay Kitazawa and Joana Simoes for their insightful discussions on agent-based modelling. To Aidan Slingsby for his comments and support when I first started to program, and to Alex Singleton and Maurizio Gibin for their many discussions.

Finally, I would like to thank my parents and my wife Sophie for all their support; it has meant so much to me.
