Vertical mergers, foreclosure and raising rivals' costs: Experimental evidence

Normann, Hans-Theo - 2010

The hypothesis that vertically integrated firms have an incentive to foreclose the input market because foreclosure raises its downstream rivals' costs is the subject of much controversy in the theoretical industrial organization literature. A powerful argument against this hypothesis is that,...

Parental paternalism and patience

Kiessling, Lukas; Chowdhury, Shyamal K.; … - 2021

We study whether and how parents interfere paternalistically in their children's intertemporal decision-making. Based on experiments with over 2,000 members of 610 families, we find that parents anticipate their children's present bias and aim to mitigate it. Using a novel method to measure...

Algorithmic and human collusion

Werner, Tobias - 2021

As self-learning pricing algorithms become popular, there are growing concerns among academics and regulators that algorithms could learn to collude tacitly on non-competitive prices and thereby harm competition. I study popular reinforcement learning algorithms and show that they develop...

Human-algorithm interaction: Algorithmic pricing in hybrid laboratory markets

Normann, Hans-Theo; Sternberg, Martin - 2022

This paper investigates pricing in laboratory markets when human players interact with an algorithm. We compare the degree of competition when exclusively humans interact to the case of one firm delegating its decisions to an algorithm, an n-player generalization of tit-for-tat. We further vary...

The Effects of Gasoline Price Regulations: Experimental Evidence

Haucap, Justus; Müller, Hans Christian - 2012

Economic theory suggests that gasoline retail markets are prone to collusive behavior. Oligopoly market structures prevail, market interactions occur frequently, prices are highly transparent, and demand is rather inelastic. A recent sector inquiry in Germany backed suspicions of tacit collusion...

Excess capacity and pricing in Bertrand-Edgeworth markets: Experimental evidence

Fonseca, Miguel A.; Normann, Hans-Theo - 2012

We conduct experiments testing the relationship between excess capacity and pricing in repeated Bertrand-Edgeworth duopolies and triopolies. We systematically vary the experimental markets between low excess capacity (suggesting monopoly) and no capacity constraints (suggesting perfect...

The willingness to sell personal data

Benndorf, Volker; Normann, Hans-Theo - 2014

We elicit the willingness to sell personal data (contact information, Facebook details, preferences) in laboratory experiments, using a BDM and take-it-or-leave-it offers. Our experiments are novel in that (i) the experiments are incentivized, (ii) the focus on privacy issues is salient, and...

Privacy concerns, voluntary disclosure of information, and unraveling: An experiment

Benndorf, Volker; Kübler, Dorothea; Normann, Hans-Theo - 2014

We study the voluntary revelation of private information in a labor-market experiment where workers can reveal their …

Organ donation in the lab: Preferences and votes on the priority rule

Herr, Annika; Normann, Hans-Theo - 2015

implementing a vote on the rule in a donation experiment, and we also elicit opinion poll-like views. We find that two-thirds of … the participants voted for the priority rule in the experiment. When asked about real-world implementation, participants … of the donation experiment were more likely to support the rule than non-participants. We further confirm previous …
