This paper investigates the impact of free trade on welfare in a two-country world modelled as an international Hotelling duopoly with quadratic transport costs and asymmetric countries, where a negative environmental externality is associated with the consumption of the good produced in the...

We modify the vertically differentiated duopoly model by André et al. (2009) replacing Bertrand with Cournot behaviour to show that firms may spontaneously adopt a green technology even in the complete absence of any form of regulation.

Acquired wisdom has it that the allocation of pollution rights to firms hinders their willingness to undertake uncertain R&D projects for environmental-friendly technologies. We revisit this issue in a model where firms strategically choose whether to participate in an auction to attain...

In this paper, we provide a very simple model to shed light on the issue of managed competition in mixed quasi-markets (i.e. regulated markets in which social and for-proÖt Örms coexist). In doing this, we consider the literature on mixed oligopolies as a reasonable reference point and try to...

This paper examines the stability conditions of the equilibria in a market where profit-maximizing and CSR firms coexist in the presence of an environmental externality. An equilibrium in mixed duopoly is stable for low impact of productivity on pollution and high CSR sensitivity to consumer...

We investigate the introduction of a minimum quality standard (MQS) in a vertically differentiated duopoly with an environmental externality. We establish that the MQS bites only if the hedonic component of consumer preferences is sufficiently strong. Then, we illustrate an underlying tradeoff...

This paper reviews the empirical evidence on commercial media bias (i.e., advertisers influence over media accuracy) and then introduces a simple model to summarize the main elements of the theoretical literature. The analysis provides three main policy insights for media regulators: i) Media...

We extend the analysis carried out by Valletti (2000) by considering an environmental externality in a vertically differentiated duopoly where firms compete à la Cournot with fixed costs of quality improvement. We show that, if the weight of the external effect is high enough, the resulting...

This paper investigates how CSR firms influence a Cournot oligopoly with pollution. We define as CSR a firm that takes into account not only its profits but also internalises its own share of the externality and is sensitive to consumer surplus. The CSR firm obtains higher profits compared to...

An integrated monopoly, where all complements forming a composite good are offered by a single firm, is typically welfare superior to a complementary monopoly. This is the "tragedy of the anticommons". We consider the possibility of competition in the market for each complement. We present a...
