Abstract: In a model of price competition single-product ¯rms compete for consumers. Consumerspurchase a variable quantity of one of the di®erentiated goods. The paper provides results onequilibrium existence when consumers are heterogeneous in their evaluation of the di®erentiatedgoods among each other, their evaluation of the di®erentiated goods relative to the outside good,and heterogeneous in income. Furthermore, I provide su±cient conditions for dominance solvabilityand monotone comparative statics.
