How Much Is the Gap? Efficient Jump Risk-Adjusted Valuation of Leveraged Certificates

This paper develops a novel and highly efficient numerical algorithm for the gap risk-adjusted valuation of leveraged certificates. The existing literature relies on Monte Carlo simulations, which are not fast enough to be used in a market making environment. This is because issuers need to compute thousands of price updates per second. By valuing leveraged certificates as multi-…

Measuring value sensitivity in medicine

Background: Value sensitivity – the ability to recognize value-related issues when they arise in practice – is an indispensable competence for medical practitioners to enter decision-making processes related to ethical questions. However, the psychological competence of value sensitivity is seldom an explicit subject in the training of medical professionals. In this contribution, we…

The Impact of Celebrity Endorsement and Celebrity Co-branding on Perceived Quality: The Role of Celebrity Application Frequency Within a Brand

Retailers have used celebrity endorsement (CE), an advertising strategy, for several decades to advertise the retailer’s brand or their private labels (PL); however, the emergence of celebrity co-branding (CCOB), a branding strategy, in combination with PL is a relatively new trend worldwide. Evidence from practice indicates that the most successful co-branded premium PL are the ones…

Team design with (female) leaders in mind: restoring equity in leadership evaluations

The leadership literature shows consistent, sizeable, and persistent effects indicating that female leaders face significant biases in the workplace compared with male leaders. However, the social identity leadership literature suggests these biases might be overcome at the team level by adjusting the number of women in the team. Building on this work, we conducted 2 multiple source…

Tx/Rx head coil induces less RF transmit-related heating than body coil in conductive metallic objects outside the active area of the head coil

The transmit–receive (Tx/Rx) birdcage head coil is often used for excitation instead of the body coil because of the presumably lower risk of heating in and around conductive implants. However, this common practice has not been systematically tested. To investigate whether the Tx/Rx birdcage head coil produces less heating than the body coil when scanning individuals with implants,…

Comparison of the working memory load in N-Back and working memory span tasks by means of EEG frequency band power and P300 amplitude

According to theoretical accounts, both, N-back and complex span tasks mainly require working memory (WM) processing. In contrast, simple span tasks conceptually mainly require WM storage. Thus, conceptually, an N-back task and a complex span task share more commonalities as compared to a simple span task. In the current study, we compared an N-back task, a complex operation span…

Impact evaluation methods in public economics : a brief introduction to randomized evaluations and comparison with other methods

Recent years have seen a large expansion in the use of rigorous impact evaluation techniques. Increasingly, public administrations are collaborating with academic economists and other quantitative social scientists to apply such rigorous methods to the study of public finance. These developments allow for more reliable measurements of the effects of different policy options on the…

You get what you 'pay' for: Academic attention, career incentives and changes in publication portfolios of business and economics researchers

Since the 1990s, research on publication outputs in business and economics has almost exclusively focused on journal articles. While earlier work has shown that journal articles and other publications were indeed complements in the 70s and 80s, we find that this is no longer the case when we include the most recent decades. Apparently, the notable shift in the scientific community’s…
