Consumers’ heterogeneity and prices in a CES -model of monopolistic competition
P. 147–154.
Osharin A., Verbus V. A.
We extend the Dixit and Stiglitz set-up by introducing consumer heterogeneity into a general equilibrium model of monopolistic competition. By getting a closedform solution for a symmetric equilibrium, we show how the market outcome depends on the joint distribution of tastes and labor productivities of consumers. In contrast to the traditional framework, the model predicts that the short-run equilibrium price may vary with the number of firms, demonstrating both anti- and procompetitive behavior, which is in accordance with economic intuition and empirical evidence.

Rangeland degradation is a global environmental challenge; however, intense debate persists between equilibrium (focused on the negative effects of grazing intensity) and non-equilibrium (emphasizing livestock mobility for adapting to climate variability) theories in rangeland ecology. In recent years, an integrative theory advocating the “coexistence of equilibrium and non-equilibrium” has emerged to reconcile this debate. However, ...

Likert scales rely on the assumption that psychological attributes are ordinal, meaning that the attribute levels a, b, and c are in transitive relations. Testing transitivity is possible through pairwise comparisons of attribute levels. Previous tests showed that people can violate transitivity, which calls into question the basic assumption of rating scales. We hypothesized that ...

The paper investigates how recent advances in the treatment effects literature can be applied to study gender pay inequality in Russia. The key parameter of interest is the mean unexplained gender wage gap. Using the RLMS HSE data for 2005–2020, we consider linear regression, Oaxaca-Blinder (OB) decomposition, and estimators based on propensity scores (PS) and ...

If bidders are better informed than the seller about a common component of auction heterogeneity, the seller can allocate more efficiently by keeping her reserve price secret and revising it using submitted bids. We build a model of a first-price auction under unobserved auction heterogeneity—imperfectly observed by the seller—that captures this rationale and derive conditions ...

The transition from the Norwegian narrative to the Icelandic one in Bjarnar saga Hítdælakappa creates such a contrast that for a long time this saga has been seen as particularly odd or clumsily made. This article argues that the contrast is due to the saga’s bipartite structure where one part serves as an introduction and ...
