Traumberuf oder Verlegenheitslösung?

So far relatively little is known about the situation of Ph.D. students in media and communication research. The main purpose of this study is, therefore, to shed light on the employment and working conditions for young scholars on their way to their doctoral degrees. We conducted a survey of 281 Ph.D. students in Germany, Switzerland and Austria. The results show that, on the one hand, young scholars are intrinsically highly motivated to do their jobs. On the other hand, they perceive an academic career as a very uncertain venture with many obstacles. Furthermore, several types of Ph.D. students can be distinguished: idealists, careerists and waverers. It is shown that only the idealists conform to the concept of a productive and interested scholar. The results are discussed in terms of their importance for the future development of the field.     

Employee Share Ownership: Safeguarding Investments in Human Capital

Valuable investments in human capital, it has been argued, may be at risk in much the same way as shareholder equity capital. In this paper, we develop and test the hypothesis that employee share ownership (ESO) may be used to encourage and safeguard investments in human capital. Using the Workplace Employee Relations Survey 1998, we examine the empirical link between the likelihood of ESO and the presence of valuable human capital. Adjusted for possible structural influences, empirical evidence suggests considerable support for our hypothesis.     

An optimization approach to business buyer choice sets: How many suppliers should be included?

In many new or repeat purchasing situations, business buyers must decide how many suppliers to consider (a “choice set”) in determining which supplier(s) to actually buy from or contract with. This paper develops an optimization approach to determining the size of the choice set, taking into consideration buyer utility and search and evaluation costs. A theoretical model is developed for both one-time and repeat purchase situations. The model is estimated using empirical data received from bids received for procurement auctions. In these auctions, suppliers provide bids for steel pipe based on two product attributes (price and delivery time). Model sensitivity to small changes in parameters is also tested.     

Risks in new product development: devising a reference tool

This paper describes the development and applicability of a risk reference framework (RRF) for diagnosing risks in technological breakthrough projects. In contrast to existing risk identification strategies, the RRF centers on an integral perspective on risk (i.e. business, technological and organizational) and the assessment of risks in ongoing projects. The resulting RRF consists of 12 main risk categories and 142 connected critical innovation issues and has been developed for a globally operating company in the fast-moving consumer goods industry. Our analyses show that to some extent different project members identified the same risks and that saturation occurred in the number of new risk-issues brought to light. We conclude that the success of breakthrough innovation projects improves through formal risk-assessment.     

Market Orientation and the New Product Paradox

The extant literature shows that the strength of the market orientation–performance relationship decays as the terminal measure of performance shifts from new product success to profitability to market share. As Day (1999) concluded, a broader nomological inquiry is needed to more fully understand the nature and limits of market orientation's effects. This suggests that a broader nomological inquiry is needed to fully understand the nature and limits of market orientation's effects.
Utilizing a national sample of marketing executives, the present study's purpose is to build a fuller understanding of the effects of market orientation on firm performance. Its structural equations model includes measures of new product success, profitability, and market share.
The research reinforces a strong positive relationship between market orientation and new product success. The expanded nomological network under study, however, implies barriers to market orientation's effectiveness. First, market-orientation-inspired increases in the priority firms place on "breakthrough" learning without commensurate increases in the priority placed on "breakthrough" innovation capabilities can boomerang and negatively impact new product success. Second, market-orientation-inspired new product development programs that are unable to increase market share can negatively impact profitability. These gatekeepers to the success of market orientation underscore the need for firms to coordinate a strong market orientation with resources and capabilities that increase the effectiveness of the marketing function. Without such coordination, the positive effect of market orientation on new product success may be limited to incremental innovations, and the overall effect of successful new products on profitability may be limited.     

Bank CEO materialism: Risk controls,culture and tail risk

We investigate how the prevalence of materialistic bank CEOs has evolved over time, and how risk management policies, non-CEO executives’ behavior and tail risk vary with CEO materialism. We document that the proportion of banks run by materialistic CEOs increased significantly from 1994 to 2004, that the strength of risk management functions is significantly lower for banks with materialistic CEOs, and that non-CEO executives in banks with materialistic CEOs insider trade more aggressively around government intervention during the financial crisis. Finally, we find that banks with materialistic CEOs have significantly more downside tail risk relative to banks with non-materialistic CEOs.     

Short-Sale Restrictions and Price Clustering: Evidence from SEC Rule 201

We provide a novel test of information-based theories of price clustering by examining trade, order, and the National Best Bid and Offer (NBBO) quote price clustering during periods when information is removed from the market. We use a natural experiment of short-sale restrictions resulting from Securities and Exchange Commission (SEC) Rule 201 to more effectively determine the impact of information on price clustering. We find evidence of increased price clustering for trades, orders, and NBBO prices during short-sale restrictions. Overall, our findings indicate that short-sale restrictions harm the price discovery process and lead to a reduction in market efficiency.
