We investigate the impact of an environmental award in a Bertrand duopoly with green consumers considering a three-stage game. First, the regulator designs the environmental contest. Second, firms choose their green investments, and the winner of the contest is awarded. Third, firms compete in...

This paper analyzes the behavior of the Argentine chocolate bar industry during the period 2019-2022. It mainly focuses on the level of competition between the firms in the industry, estimating conduct parameters that signal the existence of harder or softer competition. The estimations change...

We trace the origins of the definition of the "quality variable" used in the theory of product differentiation, which states that quality is unanimously appreciated by consumers, entails a higher unit cost for firms, is unidimensional and continuous. We also document the transition from a...

Production functions provide a mapping from the firms' input quantity and productivity to output quantity. This mapping only generates unbiased estimates if input and output quality variation within and between observation units is accounted for. I review and classify state-of-the-art methods to...

Firms often choose with whom to compete and how similar or how different their products should be relative to those of their rivals. This paper investigates this issue in the app economy by studying the determinants of mobile app success. We leverage natural language processing and unsupervised...

We model competition on a credence market governed by an imperfect label, signaling high quality, as a rank-order tournament between firms. In this market interaction, asymmetric firms jointly and competitively control the underlying quality ranking's precision by releasing individual...

We experimentally investigate exclusive-offer competition between two existing upstream firms. In theory, when upstream firms make exclusive offers to a downstream monopolist, both exclusion and non-exclusion can be equilibrium outcomes. By varying key parameters, we explore how bargaining power...

This paper introduces a novel ratio-based framework for analyzing how consumer heterogeneity translates into product differentiation in vertically structured monopoly markets. We consider a monopolist facing a continuum of consumers and a strictly convex production cost function and identify...

This paper incorporates non-homothetic preferences and the product quality ladder assumption into a model of heterogeneous multi-product firms from the perspective of scale and quality to investigate the differential impact of domestic demand upgrading on firm resource reallocation and export...

In theory, when upstream firms make exclusive offers to a downstream monopolist, both exclusion and non-exclusion can be equilibrium outcomes. By varying key parameters, we explore how bargaining power...

This paper investigates the impact of services sector liberalization on product innovation of downstream manufacturing firms. Leveraging firm-product panel data from India and employing a shift-share research design, I find that services liberalization significantly increases firms’ product...

We study information design in a vertically differentiated market. Two firms offer products of ex-ante unknown qualities. A third party designs a system to publicly disclose information. More precise information guides consumers toward their preferred product but increases expected product...

This paper studies biased-manager hiring in a market with network externalities and product compatibility. We show that the aggressivity of a biased manager has a non-linear relationship with product compatibility; however, since both owners want to hire aggressive managers, product...

The rising prevalence of greenwashing by firms has emerged as a major concern for regulatory authorities over the past decade. This paper examines the impact of regulation on firms' strategic decisions regarding greenwashing and environmental quality in an oligopolistic market. We model two...

How do environmental information and awareness interact to improve environmental quality by changing consumer behavior and firm strategies? This article provides theoretical insights using an original differentiation model within a general framework whose specific cases have been studied...
