In three essays we tackle three different topics, the first with a stronger economic focus, the second with a stronger business focus, and the third with a policy focus:

  1. “the first essay uses data that combines Call Detail Records and employment information on mobile phone subscribers to identify job information networks”
  2. “the second essay studies the impact of Time-Shift Television (TSTV) on TV consumption and advertisement viewership.”
  3. “the third essay measures the impact of DNS blocking on digital piracy and on the consumption of several legal alternatives not covered before in the literature”

The first study, focusing on consumer switching decisions, investigates the impact of lock in shortening policies on both firm profits and consumer welfare.

The later two studies focus on consumer search and purchase behaviors in a representative telecom service market where consumers shop for movies on demand.
