Exchange Days – Market Competition in the Digital Age

Virtual Brown Bag Lunch

Join us during your lunch and discuss with Prof. Dr. Andreas Hefti about Market Competition in the Digital Age.

Thursday, April 8 2021
12:00 – 13:00 


Digital markets produce an abundance of information, which makes attention a competitive resource. We study the implications of competitive attention based on two essential premises: i) People have limited information processing capacities and ii) consideration sets are formed according to the principle of relative salience.

The equilibrium predictions of the model can help to understand and connect diverse empirical phenomena in digitized competition, such as the Paradox of Choices, the power law dispersions of sales, profits or attention data, the relation between advertising expenditures and market shares, the evolution of market inequality, or why evidence favoring a “Long Tail” effect is mixed at best.
