Network Centrality and Market Prices: An Empirical NoteFirgo, Matthias, Pennerstorfer, Dieter, Weiss, Christoph 09 1900 (has links) (PDF)
We empirically investigate the importance of centrality (holding a central position in a spatial network) for strategic interaction in pricing for the Austrian retail gasoline market. Results from spatial autoregressive models suggest that the gasoline station located most closely to the market center - defined as the 1-median location - exerts the strongest effect on pricing decisions of other stations. We conclude that centrality influences firms' pricing behavior and further find that the importance of centrality increases with market size.

Centrality and Pricing in Spatially Differentiated Markets: The Case of GasolineWeiss, Christoph, Pennerstorfer, Dieter, Firgo, Matthias 05 1900 (has links) (PDF)
We highlight the importance of "centrality" for pricing. Firms characterized by a more central position in a spatial network are more powerful in terms of having a stronger impact on their competitors' prices and on equilibrium prices. These propositions are derived from a simple theoretical model and investigated empirically for the retail gasoline market of Vienna, Austria. We compute a measure of network centrality based on the locations of gasoline stations in the road network. Results from a spatial autoregressive model show that prices of gasoline stations are more strongly correlated with prices of central competitors.
