We study a two-sided markets model of two competing television stations that offer content of differentiated quality to ad-averse consumers and advertising space to firms. As all consumers prefer high over low quality content, competition for viewers is vertical. By contrast, competition for...

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...

We propose a model of environmental overcompliance in a duopoly setting where consumers are environmentally concerned and may patronise the product they buy, firms set their green investment to abate the impact of productivity on pollution and a government sets the environmental standard with...

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...

We investigate the interactions between optimal regulation and external credit constraints. When part of a regulated firm is owned by foreign investors, a credit-constrained country who wants to send profits abroad has to generate enough surplus in the trade account in order to compensate...

This Article discusses the dynamics of shared political accountability and provides a supply- and demand-side analysis of disaster management. Because multiple levels of government share political accountability in national scale disasters, disaster management is subject to a collective action...

This paper focuses on environmental policies aimed at rising investment in pollution abatement capital. Capital irreversibility is not postulated but endogenized using a quadratic adjustment cost function. We assume that ecological uncertainty, i.e. uncertainty over the dynamics of pollution,...

We ask whether regulation can usefully supplement litigation in a model of optimal social control of harmful externalities. In our model, firms choose activity levels in addition to precautions. In contrast to the usual analysis, we assume that social returns to activity are higher than private...

This paper examines the regulation of technological innovation direction under uncertainty about potential harms. We develop a model with two competing technological paths and analyze various regulatory interventions. Our findings show that market forces tend to inefficiently concentrate...
