15. Yale School of Management Location Cities from first principles Monocentric city model  William Alonso (1964) Location and Land Use  Richard Muth (1969) Cities and Housing Transportation costs Employment and shopping take place at one point Demand for housing/budget constraint Utility for leisure time

16. Yale School of Management Results Housing prices (and rents) are a decreasing function of distance from CBD. Shifts in transportation costs and travel times can be analyzed. Calculus for understanding new structure of cities. E.g. Rae (2004)

17. Yale School of Management Another Approach What are cities?  Employment  Shopping  Social centers  Private property  Public amenities What makes them grow?

19. Yale School of Management Human Capital Acquisition of labor is easier. Knowledge spillover leads to positive externalities. Diversification (Jacobs/Glaeser)  Reduces labor risk Competition  Leads to innovation Specialization (Marshall/Arrow/Romer)  Develops particular technology

20. Yale School of Management Goetzmann, Massa, Simonov Specialization: the main industry in local employment / share of this same industry in national employment. Competition: number of firms per employee in a district relative to the number of firms per employee in Sweden. Diversity is the share of the next top (after the main one) five industries in municipal employment

21. Yale School of Management Savings, Investment & Finance Urban housing less risky  Diversified industry base => smooth demand Personal Portfolios  Knowledge spillover & speculation  Time and attention

26. Yale School of Management Under-Diversification Linked to knowledge creation and spill-over in the urban environment. Spillover that characterizes city agglomeration on the one hand reduces the availability of time to collect and analyze financial information Increases the relative information that an investor has with respect to stocks professionally or geographically closer to him.

27. Yale School of Management Cities Provide investment opportunities Require less risk hedging Result in capital growth and more spillover
