我们提出了一个垄断竞争的一般模型,并利用相对多样性的概念推导了市场均衡的完整表征。当RLV随个人消费的增加而增加时,市场产生了促进竞争的效应。当它减少时,市场模仿反竞争行为。消费电子展是一个边缘案例。我们将我们的设置扩展到异质企业,并表明当RLV增加(减少)时,截止成本减少(增加)。最后,我们研究了纵向、横向和成本异质性对结果的影响。
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 market generates pro-competitive effects. When it decreases, the market mimics anti-competitive 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.
