As shown by R. Hahn [6], free allocation equal to the amount of permits a firm with market power uses in equilibrium, can prevent welfare losses. If the necessary amount of free allocation is not provided to the firm with market power, a second best solution is obtained where marginal abatement...

The paper studies the impact of homophily on the optimal strategies of a monopolist, whose marketing campaign of new product relies on a word of mouth communication. Homophily is a tendency of people to interact more with those who are similar to them. In the model there are two types of...

In a dynamic storable good market where demand changes over time, we investigate the producer's strategic incentives to hold inventories in response to the possibility of buyer stockpiling. The literature on storable goods has demonstrated that buyer stockpiling in anticipation of higher future...

This paper considers the optimal pricing and diffusion of a durable good that exhibits positive network externalities, when consumers are heterogeneous with respect to their expectations about future network sizes. We consider the existence of naive consumers, as well as of sophisticated...

In a linear bilateral monopoly with the up-stream manufacturer and the down-stream retailer “consumers’ friendly” socially concerned (i.e. caring about a share of consumer surplus), Brand and Grothe (2015, in this Journal) shows that, although (as expected) both firms’ owners do not have...

This paper studies the optimal pricing and diffusion of durable goods that exhibit positive network externalities, when consumers are heterogeneous in their expectations about future network sizes. We consider the existence of naive consumers, as well as of sophisticated consumers having...

In a storable good market, we investigate a firm’s pricing policy and the welfare effects associated with the firm’s ability to commit to future prices in the presence of time-varying production costs. We show that, if costs are expected to increase, the firm’s lack of commitment leads to...

In this article we study patterns of vertical product differentiation in a multi-product monopoly using a random utility model. Prior research shows that applying such a model in a multi-product setting implies symmetric patterns of product differentiation in which all product variants of a...

We introduce a notion of subgames for stochastic timing games and the related notion of subgame-perfect equilibrium in possibly mixed strategies. While a good notion of subgame-perfect equilibrium for continuous-time games is not available in general, we argue that our model is the appropriate...

We construct subgame-perfect equilibria with mixed strategies for symmetric stochastic timing games with arbitrary strategic incentives. The strategies are qualitatively different for local first- or second-mover advantages, which we analyse in turn. When there is a local second-mover advantage,...
