摘要：We propose a general model of monopolistic competition and derive a complete
characterization of the market equilibrium using the concept of Relative Love for
Variety. When the RLV increases with individual consumption, the marketgenerates pro-competitive effects. When it decreases, the market mimics anticompetitive
behavior. The CES is a borderline case. We extend our setting to
heterogeneous firms and show that the cutoff cost decreases (increases) when the
RLV increases (decreases). Last, we study how combining vertical, horizontal and
cost heterogeneity affects our results
