We examine the strategic use of Corporate Social Responsibility (CSR) in imperfectly competitive markets. The level of CSR determines the weight a firm puts on consumer surplus in its objective function before it decides upon supply. First, we consider symmetric Cournot competition and show that...

We compare the strategic potential of Corporate Social Responsibility and Customer Orientation as commitments to larger quantities in Cournot competition. In addition to profits, firms can choose to care for the surplus of either all consumers (CSR) or their own customers only (CO), and if so,...

This paper studies the welfare consequences of a vertical merger that raises rivals costs when downstream competition is à la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can nevertheless improve welfare if it involves a...

This study compares energy and emission taxes used to control pollution and provide incentives for the adoption of an advanced abatement technology in a Cournot oligopoly. We examine multistage games where the government may intervene in order to maximize social welfare by setting an...

We investigate the effect of a ban on third-degree price discrimination on the sustainability of collusion. We build a model with two firms that may be able to discriminate between two consumer groups. Two cases are analyzed: (i) Best-response symmetries so that profits in the static Nash...

It is widely recognized that a cost-efficient way to achieve the climate targets of the Paris agreement requires investment in carbon capture and storage (CCS). However, to trigger sizeable investment in CCS the carbon price must exceed the historic carbon prices. This paper examines whether a...

We theoretically analyse the relationship between Corporate Social Responsibility (CSR) and tax avoidance of an oligopolistic firm. The firm maximises a weighted sum of profits and a CSR objective which depends on output and the firm's contribution to public good provision, i.e. tax payments....

We examine the role of CSR as a mechanism for private provision of public goods. We argue that corporations are using CSR to signal high product quality and demonstrate that signaling gives rise to an excessive level of contributions that offsets the positive externality, which causes the...

Is green consumerism beneficial to the environment and the economy? To shed light on this question, we study the political economy of environmental regulations in a model with neutral and green consumers where the latter derive some warm glow from buying a good of higher environmental quality...

We develop a model of vertical innovation in which firms incur a market entry cost and choose a unique level of quality. Once established, firms compete for market shares, selling to consumers with heterogeneous tastes for quality. The equilibrium of the pricing game exists and is unique within...
