There are two paradigms of city formation and size-the competitive model of
large-scale land developers operating in national land markets and the sel
f-organization model of agglomeration. This paper examines the effects of l
ocal politics, urban classes, and restrictions in national land markets on
city size and formation. It starts by introducing local politics into the t
wo paradigms. Then it turns to a growth situation, where land developers in
itiate new settlements, but existing cities are either self-organized or go
verned locally. The paper also examines the politics of local no-growth mov
ements and of governance of specially favored mega-cities. (C) 2000 Academi
