Newspapers have been experiencing declining circulation figures and advertising revenues for several years. Declining advertising figures, in particular, pose a threat to newspapers - this is especially severe in the U.S. where 73 per cent of newspapers’ revenues are generated through...

In markets where sellers' marginal costs of production have a common component, they have informational advantage over buyers regarding those costs. This information asymmetry between sellers and buyers is especially relevant in markets where buyers have to uncover prices through costly search....

Our article investigates the impact of vertical integration (without foreclosure) on innovation. We compare cases where either (i) two manufacturers or (ii) a manufacturer and a vertically integrated retailer invest. Then, the independent manufacturer(s) and the retailer bargain over non-linear...

This paper analyzes a market in which two horizontally differentiated firms compete by setting menus of two-part tariffs, and in which some consumers are not informed about the linear per-unit price component. We consider two regulatory interventions that limit firms’ ability to price...

This article studies the effects of consumer information on the intensity of competition. In a two dimensional duopoly model of horizontal product differentiation, firms use consumer information to price discriminate. I contrast a full privacy and a no privacy benchmark with intermediate regimes...

Compatibility of network products is an important issue in markets for communication technology as well as hard- and software products. Empirical findings suggest that firms competing in these markets typically choose intermediate degrees of product compatibility. We present a strategic...

We empirically investigate the relevance of multi-homing in two-sided markets. First, we build a micro-founded structural econometric model that encompasses demand for differentiated products and allows for multi-homing on both sides of the market. We then use an original dataset on the Italian...

A positiv relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this oberservation. This paper analyzes an oligopoly model with asymmetric multiproduct firms,...

The economic effects of environmental taxes depend on the market structure. Under imperfect competition with free entry and exit, environmental taxes have an impact on economies of scale by changing the number and size of firms. Whether economies of scale rise or fall in a particular industry...
