Seminar Abstract 【Natural Agglomeration】 ------------------------------ Speaker: 田淵 隆俊 Affiliation: 東京大学 経済学部 Date and Time: 2003. 9. 18 (Thu), 4:30 - 6:00 p.m. Place: 3F1136 Chair: 金子 守 ------------------------------ Abstract: Based on new economic geography, we consider the racetrack economy, where manufacturing activities are distributed continuously. We show that smooth and dense distributions are always unstable equilibria, whereas agglomeration in 1 or 2 atomic cities is a stable equilibrium for any economic parameters given regular transport costs including linear ones.
