Information- and Communication Technologies (ICTs) have revolutionized existing industries spurring productivity and growth.  At the same time, they have allowed firms to bring new products and services to the markets giving way to new information industries.  Examples include Internet services, mobile telecommunications, and software industries.  These industries share special features, such as low marginal production costs, network effects, and complementarities, which have important implications for firms’ conduct and competition policy.  In this project we analyze both: the impact of ICTs on established industries, as well as the functioning of information industries.  In particular, we study issues such as:

• productivity effects of competition and ICT adoptions
• empirical identification of network effects
• ICT diffusion
• pricing and conduct in information and communications industries
