Three chapters in industrial organization
On Monday 25 October 2021 Charlotte Bjørnhaug Evensen will hold a trial lecture on a prescribed topic and defend her thesis for the PhD degree at NHH.
Prescribed topic for the trial lecture:
«Industrial Economics of Artificial Intelligence»
10:15 at Jebsen Centre, NHH
Title of the thesis:
«Three chapters in industrial organization»
The thesis consists of three chapters that analyze firm behavior, aiming to broaden the understanding of their strategic decision-making. Using both theoretical and empirical methods, the thesis covers current topics related to trade in digital and physical goods.
The first chapter focuses on digital media markets and investigates the impact of targeted advertising on platform performance and market equilibria. A central issue is whether consumers use one or more platform. Although digitalization makes it easier to use multiple platforms, existing literature typically makes the assumption that this is not possible.
This chapter relaxes this assumption and shows that it can provides strikingly different results.
The second chapter pays attention to the grocery business and the increased competition from discount variety retail. The topic is examined using data from a large Norwegian grocery chain and the discount variety chain Europris. Our results suggest that the effect of Europris establishments on grocery store performance depends on the distance between the stores. If Europris locates sufficiently close, the grocery stores benefits from increased local demand. For locations further away, the negative effect due to increased competition for products that are offered by both chains dominates. For even greater distances, there is eventually no effect.
The third chapter concentrates on price setting by dominant suppliers, aiming to shed light on why they price discriminate and in what situations they would be better off by committing to uniform pricing. Our model shows that the optimal price setting depends on the retailers’ incentives to invest in a substitute to the suppliers’ products as well as the competitive pressure in the retail market. Interestingly, the paper also finds that supplier and consumers tend to prefer different pricing strategies.
