Structural remedies as a signaling device

We analyze the effects of structural remedies on merger activity when the Antitrust Agency (AA) cannot observe a proposed merger’s efficiency type. Provided the AA follows a consumer surplus standard, an efficient merger type is doomed to over-fix with its divestiture proposal in a pooling equilibrium, which is also possible under separation.

Salience and Health Campaigns

Abstract Motivated by current topics in health economics, we apply the theory of salience to consumer policy. If a government intends to encourage healthier diets without harming consumers by raising taxes, it could initiate information campaigns which focus consumers’ attention either on the healthiness of one item or the unhealthiness of the other item. According to our approach, both campaigns work, but it is more efficient to proclaim the unhealthiness of one product in order to present it as a “ bad.” Our findings imply that comparative advertisement is particularly efficient for entrant firms into established markets.

Explaining Gender Differences in Competitiveness: Testing a Theory on Gender-Task Stereotypes

We examine an explanation for differences of self selection into competitive environments between men and women: gender-task stereotypes. Via data from a laboratory and a framed field experiment we test a recent model on stereotyping. Therefore, we contrast genders’ competitiveness between three tasks, two of which are male-connotated and one of which is not strongly associated with gender. An indirect test ensures that our quantitative and our sports task are stereotypically male, while for the verbal task concerning gender performance are absent. Controlling for potential confounds, we find that women self-select significantly less into competition against men only such tasks which are stereotypically male. In addition, we show that these stereotypes not only have consequences for the self selection into payment regimes, but also, for instance, for the selection of partners under the examined payment regimes. Overall, our results imply that the existence of gender connotations of tasks triggers significant gender effects with respect to different dimensions such as competitiveness, performance or partner choice. In particular, our experimental analysis strongly supports the underlying theory on stereotypes.
