Overspending in the Videogames Market - Job Market Paper [PDF]

Abstract: This paper studies overspending in the videogames market resulting from purchasing games and never opening them later. According to the descriptive statistics around 28% of games in people’s game libraries are unopened at the moment. The main data are gathered from Steam, one of the biggest online gaming platforms. It contains daily purchasing and consumption statistics as well as daily prices in 40 currencies for the period of 5 months. I overview the mechanisms that may be causing such behavior, and conclude that it is due to biased beliefs about future consumption of new games. I build a structural model that takes this behavior into account and quantify the bias.
