SHORT‐MATURITY OPTIONS AND JUMP MEMORY

We investigate jump memory using an extensive database of short‐term S&P 500 index options. Jump memory refers to the attenuation of the implied jump intensity and magnitude parameters following a crash event. We use a genetic algorithm to obtain a time series of implied parameter estimates and posit behavioral and rational explanations for parameter attenuation following a crash event. We find that a nested form of the jump‐diffusion model sharpens the remaining parameter estimates and has a negligible effect on pricing accuracy.

Stock market perceptions of the motives for mergers in cases reviewed by the UK competition authorities: an empirical analysis

A number of studies have considered the motivation of managers to follow a merger strategy. However, as far as we are aware none has looked at the influence of competition regulation on merger motives using stock market data and event study techniques. Data drawn from 63 merger cases in the UK between 1989 and 2003 are examined for the stock market's perceptions of what motivated managers to pursue their initial merger bid. The findings suggest that the Synergy and Hubris dominate as motivations for mergers and that, unintentionally, competition policy may help to reduce the number of mergers motivated by Managerialism.

Research findings in strategic management with implications for R&D management

Abstract
The author has reviewed the literature, predominantly North American, on the relationships between corporate strategy and corporate performance.
The general context is the question of where and how a firm should diversify. The author considers three areas of decision: corporate strategy, (where to compete), business strategy, (how to compete), and corporate organization (receptiveness to diversification). It appears that the most advantageous corporate strategy is to diversify into a high-profit area but to maintain a substantial relatedness to existing businesses; the best business strategy is to have a market-related perspective, to use R&D to develop new products with a marked competitive advantage rather than new processes, to minimise investment but to enter the market on a sufficiently large scale. This last condition presupposes a high degree of top-management commitment to the venture. Furthermore, consideration has to be given to whether the organizational culture is such as to nurture rather than stifle the venture by insisting on administrative controls appropriate to the firm's traditional base.
The author points to three areas deserving of further investigation: How a firm in a mature industry can find a related area that is sufficiently attractive; how to fix on the correct scale of an entry taking into account the long lead times before the venture shows a net return; and how to ensure that the corporate culture will be able to accommodate novel interests and procedures.
All the above matters pose questions for the management of technology and the direction of R&D.     

Order management for profit on the Internet

To succeed, Internet retailers must make a profit on the goods and services they sell. But e-tailers are still searching for strategies that work. To test current practices, we became “phantom shoppers” and bought a randomly chosen set of CDs from a variety of Internet retailers. Our findings suggest that order management and logistics skills are pivotal for selling profitably on the Internet. In this article, we show how Internet retailers can deploy resources creatively to attract the right shoppers, convert these shoppers into buyers, and improve the chances of repeat purchase while maintaining profit margins.     

Metropolitan innovation,firm size,and business survival in a high-tech industry

This paper contributes to the growing body of business survival literature that focuses on regional determinants of the hazard faced by firms. Using parametric survival analysis, we test the effects of regional innovation on exit likelihood in the US computer and electronic product manufacturing during the 1992–2008 period. The novelty of our approach is in conditioning the effects of metropolitan innovation on firm size. Estimation results suggest a negative relationship between metropolitan patenting activity and survival of firms that started with 1–3 employees. This effect decreases if companies grow. Establishments with more than 4 employees at start-up are insensitive to metropolitan innovation, although size of firms that started with 4–9 employees improves their survival chances. These findings indicate that local knowledge spillovers do not translate into lower hazard. The negative relationship indicates either a creative destruction regime or decisions of entrepreneurs to shut down existing ventures in order to pursue other opportunities.     

Hedonic shopping motivations in collectivistic and individualistic consumer cultures

We reinvestigate what constitutes hedonic customer experiences in collectivistic versus individualistic cultures using four country samples (N=2,336) in Germany and the U.S. as well as Oman and India. Across country samples, intrinsically enjoyable customer experiences are associated with the same underlying hedonic shopping motivations as shown in the original U.S. context. In comparison with individualistic cultures, we find that a hedonic shopping experience in collectivistic cultures is less strongly associated with selforiented gratification shopping, yet more strongly associated with others-oriented role shopping.     

Innovation forecast: Un-avoidable and context dependent

In order to mobilize the necessary resources for innovation forecasts are unavoidable. However, a forecast is never a neutral or objective assessment. Given an interdependent business landscape, there are at least two major context-related aspects that affect an innovation forecast. First, the actor that makes the forecast is embedded into a specific context. Secondly, the potential innovation stems from a specific environment, and will during the innovation journey be related to other environments in a producing and a using setting, and thus to other investments in place. In this paper we examine the development of one innovation and the forecasts made by three different economic actors. There is an interesting variation in the forecasts that can be explained as a variation of contexts of the actors. The contexts influence the way that the forecasts are done and especially in terms of what the context of the innovation is assumed to be. The empirical findings suggest that the results of the innovation forecast are highly dependent on the actors' abstraction of the business landscape which in turn is affected by the contexts of the actors.
