    Description: Despite the prevalence of non-routine analytical team tasks in modern economies, little is known about how incentives influence performance in these tasks. In a field experiment with more than 3000 participants, we document a positive effect of bonus incentives on the probability of completion of such a task. Bonus incentives increase performance due to the reward rather than the reference point (performance threshold) they provide. The framing of bonuses (as gains or losses) plays a minor role. Incentives improve performance also in an additional sample of presumably less motivated workers. However, incentives reduce these workers’ willingness to “explore” original solutions.

    Description: Do people blame refugees for negative events? We propose a novel experimental paradigm to measure discrimination in responsibility attribution towards Arabic refugees. Participants in the laboratory experience a positive or negative income shock, which is with equal probability caused by a random draw or another participant's performance in a real effort task. Responsibility attribution is measured by beliefs about whether the shock is due to the other participant's performance or the random draw. We find evidence for reverse discrimination: Natives attribute responsibility more favorably to refugees than to other natives. In particular, refugees are less often held responsible for negative income shocks. Moreover, natives with negative implicit a sociations towards Arabic names attribute responsibility less favorably to refugees than natives with positive associations. Since neither actual performance differences nor beliefs about natives' and refugees' performance can explain our finding of reverse discrimination, we rule out statistical discrimination as the driving force. We discuss explanations based on theories of self-image and identity concerns.

    Description: Most economic decisions are embedded in a specific social context. In many such contexts, individual choices are influenced by their observability due to underlying social norms and social image concerns. This study investigates the impact of choices being observed, compared to anonymity of choices, on risk taking in a laboratory experiment. I relate participants\' investments in a risky asset directly to social norms for risk taking that are elicited in an incentivized procedure. I find that risk taking is not affected by the choice being observed by a matched participant. Nor do investments follow elicited norms for risk taking more closely when observed. This holds when considering males and females separately. However, I provide strong evidence for gender-specific norms in risk taking. While these explain part of the existing gender gap in risk taking, males still \"overshoot\" by investing more than the norm dictates. This is particularly true for males being matched with a female participant.

    Description: Hereditary neuropathies comprise a wide variety of chronic diseases associated to more than 80 genes identified to date. We herein examined 612 index patients with either a Charcot-Marie-Tooth phenotype, hereditary sensory neuropathy, familial amyloid neuropathy, or small fiber neuropathy using a customized multigene panel based on the next generation sequencing (NGS) technique. In 121 cases (19.8%), we identified at least one putative pathogenic mutation. Out of these, 54.4% showed an autosomal dominant, 33.9% an autosomal recessive, and 11.6% an X-linked inheritance. The most frequently affected genes were PMP22 (16.4%), GJB1 (10.7%), MPZ and SH3TC2 (both 9.9%), and MFN2 (8.3%). We further detected likely or known pathogenic variants in HINT1, HSPB1, NEFL, PRX, IGHMBP2, NDRG1, TTR , EGR2, FIG4, GDAP1, LMNA, LRSAM1, POLG, TRPV4, AARS, BIC2, DHTKD1, FGD4, HK1, INF2, KIF5A, PDK3, REEP1, SBF1, SBF2, SCN9A, and SPTLC2 with a declining frequency. Thirty-four novel variants were considered likely pathogenic not having previously been described in association with any disorder in the literature. In one patient, two homozygous mutations in HK1 were detected in the multigene panel, but not by whole-exome-sequencing. A novel missense mutation in KIF5A was considered pathogenic due to the highly compatible phenotype. In one patient, the plasma sphingolipid profile could functionally prove the pathogenicity of a mutation in SPTLC2 . One pathogenic mutation in MPZ was identified after being previously missed by Sanger sequencing. We conclude that panel based NGS is a useful, time- and cost-effective approach to assist clinicians in identifying the correct diagnosis and enable causative treatment considerations.
