Spatial Development [PDF]

open access: yesSSRN Electronic Journal, 2009
We present a theory of spatial development. Manufacturing and services firms located in a continuous geographic area choose each period how much to innovate.

On developability [PDF]

open access: yesProceedings of the American Mathematical Society, 1982
The converse of an old result of Bing turns out to be a very interesting characterization of developability. It is interesting in the sense that it provides a unifying framework for certain classical results of Bing, F. B.

Geography and Development [PDF]

open access: yesJournal of Economic Geography, 2000
The most striking fact about the economic geography of the world is the uneven spatial distribution of economic activity, including the coexistence of economic development and underdevelopment. High-income regions are almost entirely concentrated in a few temperate zones, half of the world's GDP is produced by 15 percent of the world's population, and ...

Spite and Development [PDF]

open access: yesAmerican Economic Review, 2008
In a wide variety of settings, spiteful preferences would constitute an obstacle to cooperation, trade, and thus economic development.
