Health Information on the Internet

Electronic Health (e-Health) increasingly strives to provide health information and services to healthcare stakeholders via the Internet, and to actively involve patients in their care. One major chance for these participatory healthcare and patient-centered approaches that integrate patients in healthcare are the phenomena and ideas associated with providing information and healthcare on the Internet. This paper examines the existing body of knowledge on online health information and explores the current state of research through a review of literature as well as past and current research projects. The fundamental categories of the analysis represent the stakeholders in the healthcare sector, the connecting information flows, the information-transferring technological applications, as well as the categories of the TEMPEST model. Based on these findings, causes and future research fields are discussed. The technological category has the largest share of all categories. Based on these findings, causes and future research fields are discussed.     

Importance of spatial proximity between venture capital investors and investees in Germany

Based on 1182 dyads of venture capitalists and German portfolio companies involved in a financing round between 2002 and 2007, the study here examines the importance of spatial proximity between investors and investees in a dense economy. Analysis of this data shows that the probability of a financing relationship decreases by 8% if the journey time increases by one standard deviation. For deals involving very small or very large investment sums, and for less experienced venture capitalists and lead investors, spatial proximity is particularly important. The results suggest that even in economies with a dense infrastructure such as Germany spatial proximity between investor and investee impacts the likelihood of an investment.     

Experimental evidence that quorum rules discourage turnout and promote election boycotts

Many democratic decision making institutions involve quorum rules. Such rules are commonly motivated by concerns about the “legitimacy” or “representativeness” of decisions reached when only a subset of eligible voters participates. A prominent example of this can be found in the context of direct democracy mechanisms, such as referenda and initiatives. We conduct a laboratory experiment to investigate the consequences of the two most common types of quorum rules: a participation quorum and an approval quorum. We find that both types of quora lead to lower participation rates, dramatically increasing the likelihood of full-fledged electoral boycotts on the part of those who endorse the Status Quo. This discouraging effect is significantly larger under a participation quorum than under an approval quorum.     

Flying under the radar: The effects of short-sale disclosure rules on investor behavior and stock prices

We study how disclosure requirements for large short positions affect investor behavior and security prices. Short positions accumulate just below the applicable disclosure threshold as certain investors never disclose any of their positions. Further tests suggest that this secrecy is part of investors’ general policy of avoiding disclosure to protect their unique, profitable investment strategies against reverse engineering by competitors. No evidence supports the notion that short sellers avoid disclosure because of potential adverse effects on securities' lending fees, risk of recall, or short squeezes. Finally, the evasive behavior by short sellers in response to transparency regulations hampers price discovery.     

Does female management influence firm performance? Evidence from Luxembourg banks

In this study, we examine the relationship between the proportion of women in top management positions at banks and these institutions’ financial performance. Using prudential data from supervisory reporting for all credit institutions in the Grand Duchy of Luxembourg from 1999 to 2013, we find a positive association between female management and firm performance. The economic effect is substantial: a 10 % increase in women in top management positions improves the bank’s future return on equity by more than 3 % p.a. Moreover, we show that this positive relationship is (i) almost twice as large during the global financial crisis than in stable market conditions and (ii) non-linear, with banks having 20–40 % female management being the most successful.
