A use-or-lose provision requires firms to employ a certain minimum fraction of their productive capacity. Variants have been used by regulators in the airline, natural gas transmission, and electric power industries, among others. The primary objective of these provisions is to limit capacity...

This paper studies the design of sin taxes when firms exercise market power. We outline an optimal tax framework that highlights how market power impacts the efficiency and redistributive properties of sin taxation, and quantify these effects in an application to sugar-sweetened beverage...

Attribute-based subsidies (ABS) are commonly used to promote the diffusion of energy-efficient products, whose manufacturers often wield significant market power. We develop a theoretical framework for the optimal design of ABS to account for endogenous product attributes, environmental...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with minority shareholdings. We find that, with high market concentration and sufficiently convex demand, there is no scope for cross-ownership to improve welfare regardless of spillover levels. Otherwise,...

This paper shows the strategic aspects of international outsourcing in a duopolistic market. Due to different costs of integrated production and outsourcing, the choice of a firm influences the strategy of the competitor via the output price. Therefore, the resulting market constellation depends...
