In this paper, under the assumption that green consumption has (at least partially) a social/psychological dimension, we analyse the effect of a carbon tax when it is imposed on consumers buying dirty products rather than on polluting firms. The amount of the tax paid is determined by the share...

In the recent last years, in particular in the aftermath of the global financial and economic crisis, many countries initiated economic recovery plans with a major focus on stimulating green entrepreneurial activities to revive economic growth. Further, the recovery plans intend to improve a...

In this paper, I compare two-part tariff competition to linear pricing in a vertically differentiated duopoly. Consumers have identical tastes for quality but differ in their preferences for quantity. The main finding is that quality differentiation occurs in equilibrium if and only if two-part...

We investigate what kind of competitive pressure induces existing firms to engage in more intensive innovation activities. We examine two types of competitive pressure: a price decrease in competitive fringe firms and a quality improvement therein. We use an oligopoly model with vertical...

This paper studies how the emergence of specialized communication media focused on both high quality contents and high quality advertised products, affects the functioning of a vertically differentiated market. To that end, we formulate a simultaneous game of pricing and targeted advertising...

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...

The paper proves the existence of a subgame perfect Nash equilibrium in a vertically differentiated duopoly with uncovered market, for a large set of symmetric and asymmetric distributions of consumers, including, among others, all logconcave distributions. The proof relies on the 'income share...

In the framework of a vertically differentiated mixed duopoly, with uncovered market and costless quality choice, we study the existence of a price equilibrium when a welfare-maximizing public firm producing low quality goods competes against a profit-maximizing private firm producing high...

This paper analyses a model of vertical product differentiation with one incumbent and one entrant firm. It is shown that if firms can produce only one quality level welfare in this entry game can be lower than in monopoly. This is the case if qualities are strategic complements because the...
