Editorial

Conclusion We keenly feel the loss of our friend, Murray N. Rothbard. We shall strive to follow the path he so ably blazed. Although none of us ever studied formally with Murray, he was our intellectual guide and mentor. He will be sorely missed.Co-editors of theReview of Austrian Economics are: Walter Block, associate professor of economics at The College of the Holy Cross, Hans-Hermann Hoppe, professor of economics at the University of Nevada, Las Vegas, and Joseph T.

The costs and benefits of additional information in agency models with endogenous information structures

We study the effect of additional private information in an agency model with an endogenous information structure. If more private information becomes available to the agent, this may hurt the agent, benefit the principal, and affect the total surplus ambiguously.     

Gumbel’s Identity,Binomial Moments,and Bonferroni Sums

Gumbel’s Identity equates the Bonferroni sum with the k ‐ th binomial moment of the number of events M_n which occur, out of n arbitrary events. We provide a unified treatment of familiar probability bounds on a union of events by Bonferroni, Galambos–Rényi, Dawson–Sankoff, and Chung–Erdös, as well as less familiar bounds by Fréchet and Gumbel, all of which are expressed in terms of Bonferroni sums, by showing that all these arise as bounds in a more general setting in terms of binomial moments of a general non‐negative integer‐valued random variable. Use of Gumbel’s Identity then gives the inequalities in familiar Bonferroni sum form. This approach simplifies existing proofs. It also allows generalization of the results of Fréchet and Gumbel to give bounds on the probability that at least t of n events occur for any A further consequence of the approach is an improvement of a recent bound of Petrov which itself generalizes the Chung–Erdös bound.

Second-Mover Advantages in Dynamic Quality Competition

This paper explores a dynamic model of product innovation, extending the work of Dutta, Lach, and Rustichini (1995). It is shown that if R&D costs for quality improvements are low, the dynamic competition is structured as a race for being the pioneer firm with payoff equalization in equilibrium, but switches to a waiting game with a second-mover advantage in equilibrium if R&D costs are high. Moreover, the second-mover advantage increases monotonically as R&D becomes more costly.     

DUOPOLISTIC HIRING AND SALES COMPETITION—A THEORETICAL AND EXPERIMENTAL ANALYSIS

Two firms compete in selling as well as hiring, where sales levels depend on the hired workforce. There are two types of workers, mobile and immobile, differing in effort costs, and two workers of each type. The principals offer contracts to all workers, who then select an employer. Finally, the workers determine production levels and profits. Our experimental results show: vanishing cost differences between mobile and immobile workers induce monopolistic hiring but low profits. In contrast, large cost differences result in higher profits and allow for various hiring constellations such as one firm hiring only low‐cost workers.     

Betriebsunterbrechungsversicherung bei kleinen und mittleren Unternehmen

The business interruption caused by a property claim is an existential risk both for large industrial companies and for small to medium enterprises (SME). It is especially relevant for companies working on a more complex sales and production infrastructure. Statistics show that in case of a large property claim the cost of the accompanying business interruption claim frequently exceeds the property claim. In Germany, however, the share of companies opting for business interruption insurance is much smaller than those opting for property insurance. This is especially true for SME that can hardly cover the risk themselves. The goal of this paper is to analyze the insurance decision for a business interruption policy with a special focus on SME. As a database we use the results of a representative survey among 1802 German SME with up to 100 employees. Our results show that the decision for a business interruption policy is not only dependent on hard factors such as company size and industry, but also driven by the so-called “insurance mentality”, which includes risk aversion, insurance know-how and price-sensitivity.     

Brand Community Members as a Source of Innovation

Brand community members have a strong interest in the product and in the brand. They usually have extensive product knowledge and engage in product‐related discussions; they support each other in solving problems and generating new product ideas. Therefore, brand communities can be a valuable source of innovation. So far, little is known about the member's ability and willingness to participate in a company's innovation process. How does passion for the brand, affiliation to the brand community, and trust in the brand affect the willingness to engage in a company's innovation process? What is the effect of brand passion on brand knowledge and on domain‐specific skills, which are considered important prerequisites for qualified and creative contributions to new product development? What is the effect of personality traits on the willingness and ability to engage in new product development? This research addresses these questions, which are interesting for managers who are thinking about opening up their innovation process and collaborating with brand communities and for academics exploring the opportunities of online communities for new product development and trying to develop promising new forms of open innovation networks. Drawing on brand community literature, relationship theory, creativity theory, and personality traits research, this paper introduces a comprehensive set of antecedents affecting brand community members' willingness to engage in new product development. It is argued that consumer creativity, identification with the brand community, and brand‐specific emotions and attitudes (passion and trust) as well as brand knowledge are important determinants of consumers' willingness to share their knowledge with producers. The paper also identifies two personality traits (i.e., extraversion and openness) that have significant influence on brand passion, creativity, and identification with the community. The hypotheses are tested on a sample of 550 members of the Volkswagen Golf GTI car community. Structural equation modeling was used to test the relationship among the constructs. Though a positive disposition toward a brand may be advantageous for consumers that are willing to interact with producers during new product development, our results show that it is consumer interest in innovations and the innovative process that drives them to get involved. Further, brand community members with more knowledge and more innovative skills seem to be more willing to contribute than less qualified community members.
