We explore the incentives of a vertically integrated incumbent firm to license the production technology of its core input to an external firm, transforming the licensee into its input supplier. We find that the incumbent opts for licensing even when licensing also transforms the licensee into...

Empirical evidence suggests that people dislike ads in media products like TV programs. In such situations standard economic theory prescribes that the advertising volume can be optimally reduced by levying a tax on ads. However, making use of recent advances in the theory of Industrial...

We study the effects of horizontal mergers when firms compete on quality and price. Two key factors are identified: (i) the magnitude of variable quality costs, and (ii) the relative magnitudes of cross-quality and cross-price effects on demand. The merging firms will increase (reduce) both...

We investigate the relation between Net Neutrality regulation and Internet fragmentation. We model a two-sided market, where Content Providers (CPs) and consumers interact through Internet Service Providers (ISPs), and CPs sell consumers' attention to advertisers. Under Net Neutrality, a...

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...

Digital media goods and digital media platforms exhibit cost structures and network effects that imply that price and quantity effects of consumption taxes are qualitatively different compared to what we typically find for physical goods. For instance, in most European countries and US states,...

Standard media economics models imply that increased platform competition decreases ad levels and that mergers reduce per-viewer ad prices. The empirical evidence, however, is mixed. We attribute the theoretical predictions to the combined assumptions that there is no advertising congestion and...

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...

This paper aims at providing an explanation of the observed espresso price dispersion across major Italian cities. The empirical evidence suggests a positive relationships between the average espresso price in a city and the number of coffee shops (normalized for the adult population) operating...

Economic theory provides ambiguous and conflicting predictions about the association between algorithmic pricing and competition. In this paper we provide the first empirical analysis of this relationship. We study Germany’s retail gasoline market where algorithmic-pricing software became...
