We explore the existence of first mover advantages in mobile telecommunications markets. Building on a data set comprising monthly penetration rates, market concentration, number of active operators, and market shares of 90 followers from 33 OECD countries, we estimate a dynamic growth model....

This note analyzes the existence of a possible media bias by determining the impact of automobile manufactures' advertisements on the probability that German car magazines review their products. By accounting for possible endogeneity, we find a positive impact of advertising volumes on test...
