摘要：
In a model of price competition single-product firms compete for consumers. Consumers purchase a variable quantity of one of the differentiated goods. The paper provides results on equilibrium existence when consumers are heterogeneous in their evaluation of the differentiated goods among each other, their evaluation of the differentiated goods relative to the outside good, and heterogeneous in income. Furthermore, I provide sufficient conditions for dominance solvability and monotone comparative statics. Classification Numbers: D43, D11. (C) 2000 Academic Press.
