Pointwise agglomeration in continuous racetrack model

Using analytical methods they devised, the authors intend to study economic aspects of racetrack economy described as a continuous-space version new geography model. The main mathematical conclusions are summarized follows: 1) Workers and firms agglomerate only finite number cities, maximum possible emerging cities reduces preference for variety increases or transport cost decreases. 2) further apart located from each other, more stable city configuration is against increasing decreasing cost.
