| Abstract: | This paper studies optimal pricing in networks in the presence of local consumption or price externalities. It analyzes the relation between prices and nodal centrality measures. Using an asymptotic approach, it shows that the ranking of optimal prices and strategies can be reduced to the lexicographic ranking of a specific vector of nodal characteristics. In particular, this result shows that with positive consumption externalities, prices are higher at nodes with higher degree, and with relative price externalities, prices are higher at nodes which have more neighbors of smaller degree. |

| Abstract: | Concert tickets can either be sold at a single price or at multiple prices corresponding to different seating categories. We study the relationship between price discrimination and revenue by examining variations in the number of seating categories across concert, tour, artist, location, and time. Offering multiple seating categories leads to revenues that are approximately 5 percent higher than with single price ticketing. The return to price discrimination is higher in markets with more heterogeneous demand, in smaller venues and in more competitive markets. The return of increasing from three to four categories of seating is about half that of increasing from one to two. |
| Keywords: | Price discrimination, return to price discrimination, second degree price discrimination |

| Abstract: | In this paper the problem of a city with access to two firms or facilities (shopping malls, airports, commercial districts) selling a differentiated product (shopping, flights) and/or offering a differentiated workplace is studied. Transport connections to one facility are congested. A model is presented for this asymmetric duopoly game that can be solved for a Nash equilibrium in prices and wages. A comparative statics analysis is used to illustrate the properties of the equilibrium. A numerical model is then applied to the two Brussels airports. Three stylised policies are implemented to address the congestion problem: expansion of transport capacity; congestion pricing; and a direct subsidy to the uncongested facility. Our results indicate that the degree of intrinsic differentiation between the two firms is crucial in determining the difference in profit and market share. Price and wage differences also depend on trip frequency and consumer preferences for diversity. Congestion pricing is the most effective policy tool but all three options are shown to have attractive attributes. |
