For this purpose,\r\nwe administered a series of experiments during the final exam of a university\r\ncourse. We confronted three cohorts of undergraduate students with a set of bonus\r\nquestions and the choice between an absolute and a tournament grading scheme\r\nfor these questions. To test the moderating impact of task difficulty, we (randomly)\r\nvaried the difficulty of the questions between treatment groups. We find that, on\r\naverage, women are significantly less likely to select the tournament scheme. However,\r\nthe results show that the gender gap in tournament entry is sizable when the\r\nquestions are relative easy, but much smaller and statistical insignificant when the\r\nquestions are difficult." author: - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer - first_name: Thomas full_name: van Huizen, Thomas last_name: van Huizen - first_name: 'Linda ' full_name: 'Keijzer, Linda ' last_name: Keijzer - first_name: 'Sarah ' full_name: 'Rezaei, Sarah ' last_name: Rezaei - first_name: Stephanie full_name: Rosenkranz, Stephanie last_name: Rosenkranz - first_name: 'Bastian ' full_name: 'Westbrock, Bastian ' last_name: Westbrock citation: ama: 'Hoyer B, van Huizen T, Keijzer L, Rezaei S, Rosenkranz S, Westbrock B.

We supplement this data with data generated in a survey among the students who participated in the clearinghouse. We find that under the current mechanism over 74% of students act strategically by misrepresenting at least one of their preferences. Nevertheless, not all students are able to improve their outcome by doing so. We show that this is mainly due to the incomplete information of students and naiveté. Sophisticated students actually reach significantly better outcomes than naive students. Thus, we find evidence that naive students are exploited by sophisticated students in an incomplete information setting. article_type: original author: - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer - first_name: Nadja full_name: Stroh-Maraun, Nadja id: '13264' last_name: Stroh-Maraun citation: ama: Hoyer B, Stroh-Maraun N.

We validate this empirically using the American Inventors Protection Act (AIPA), three complementary identification strategies, and a new measure of blocked future patent applications. We show that AIPA—intended to reduce duplication, through default disclosure of patent applications 18 months after filing—reduced duplication in the U.S. and European patent systems. The blocking measure provides a clear and micro measure of technological competition that can be aggregated to facilitate the empirical investigation of innovation, firm strategy, and the positive and negative externalities of patenting.

The prices are regulated and providers compete in location and quality. We show that whereas opening a public hospital market typically raises quality, the private provider strategically locates towards the corner of the market to avoid costly quality competition. Social welfare depends on the size of the regulator's budget and on the altruism of the public provider. If the budget is large, high quality results and welfare is highest in a duopoly whenever entry is optimal. If the budget is small, quality levels in a duopoly mirror the quality level in a monopoly. It can be optimal for the regulator not to use the full budget. article_type: original author: - first_name: Burkhard full_name: Hehenkamp, Burkhard id: '37339' last_name: Hehenkamp - first_name: 'Odvar M.

Underlying a Bertrand model of price competition, we empirically model pricing behaviour in an oligopoly. We analyse panel data of individual pricing information of mobile phone contracts offered between 2011 and 2017. We provide empirical evidence that price differences as well as reputational effects serve as a signal to buyers and significantly affect market demand. Additionally, we find that brands lead to an increase in demand and thus are able to generate spillover effects even after price increase. author: - first_name: Daniel full_name: Kaimann, Daniel id: '18949' last_name: Kaimann - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer citation: ama: 'Kaimann D, Hoyer B.

An interesting scenario\r\nis the formation of an information network where group members individually sponsor costly links. Suppose that ceteris paribus, an outsider\r\nappears who aims to disrupt the information \r\nflow within the network\r\nby deleting some of the links. The question is how the group responds\r\nto this common enemy. We address this question for the homogeneous\r\nconnections model of strategic network formation, with two-way \r\nflow of\r\ninformation and without information decay. For sufficiently low linkage\r\ncosts, the external threat can lead to a more connected network, a positive\r\ncommon enemy effect. For very high but not prohibitively high linkage\r\ncosts, the equilibrium network can be minimally connected and efficient\r\nin the absence of the external threat whereas it is always empty and ineffi\fcient in the presence of the external threat, a negative common enemy\r\neffect. For intermediate linkage costs, both connected networks and the\r\nempty network are Nash for certain cost ranges." author: - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer - first_name: Hans full_name: Haller, Hans last_name: Haller citation: ama: Hoyer B, Haller H.
