PREFERENCE HETEROGENEITY AND ECONOMIC GEOGRAPHY*
研究了技能工人与非技能工人之间的偏好差异如何影响经济活动的集聚，发现当技能工人对现代商品及其多样性的偏好足够强时，企业定价可能随本地企业数量增加而上升，在低贸易成本时成为分散力、高贸易成本时成为集聚力。
ABSTRACT We investigate the effect of preference heterogeneity between skilled and unskilled workers on agglomeration, and we identify a new source of dependence of equilibrium prices on the demand properties shaped by the inter‐regional distribution of workers. We find a new preference effect, and we show that when the intensity of skilled workers' preference for the modern good and its variety is strong enough, prices charged by firms may even increase when the mass of local firms increases, therefore acting as a new dispersion force when trade costs are low or as a new agglomeration force when trade costs are high.
