Innovation strategies in the electronic mail marketplace

The author examines several crucial aspects of three types of office communications technologies: facsimile, communicating word processors, and computer based message systems. By identifying the technical, service and cost characteristics of each, he analyzes and compares their potential patterns of adoption and innovation.     

Sampling distribution of the relative risk aversion estimator: Theory and applications

Brown and Gibbons (1985) developed a theory of relative risk aversion estimation in terms of average market rates of return and the variance of market rates of return. However, the exact sampling distributions of the relative risk aversion estimators have not been derived. The main purpose of this paper is to derive the exact sampling distribution of an appropriate relative risk aversion estimator. First, we have derived theoretically the density of Brown and Gibbons' maximum likelihood estimator. It is shown that the centralt is not appropriate for testing the significance of estimated relative risk aversion distribution. Then we derived the minimum variance unbiased estimator by a linear transformation of the Brown and Gibbons' maximum likelihood estimator. The density function is neither a central nor a noncentralt distribution. The density function of this new distribution has been tabulated. There is an empirical example to illustrate the application of this new sampling distribution.     

First-mover (dis)advantages: retrospective and link with the resource-based view

This article reflects upon and updates our prize-winning paper, ‘First-mover advantages,’ which was published in SMJ 10 years ago. We discuss the evolution of the literature over the past decade and suggest opportunities for continuing research. In particular, we see benefits from linking empirical findings on first-mover advantages with the complementary stream of research on the resource-based view of the firm. © 1998 John Wiley & Sons, Ltd.     

The Impact of Biofuel Policies on Crop Acreages in Germany and France

A major concern about biofuels is that increasing biofuel feedstock demand reduces availability of crops for food and feed leading to higher food prices. This paper investigates relations between biofuel policies and prices of rapeseed, the major feedstock used for biodiesel production in Europe, and the impact of rapeseed prices on crop acreages in Germany and France. Biodiesel is an important biofuel in Europe, and Germany and France are the largest biodiesel producers in Europe. First, the various biofuel policies in Germany and France are discussed, followed by an analysis of their effects on rapeseed prices. Although theory indicates that such effects exist, we could not find empirical evidence for them. Second, using regional land use panel data from Germany and France we investigate empirically whether crop shares have been affected by rapeseed prices in the period 2000–2015 and whether these price effects changed because of biofuel policy changes. Results show that wheat shares in Germany and France did respond to rapeseed prices, but barley shares did not. Moreover, mandatory blending introduced in Germany in 2007 and production quotas introduced in France in 2005 led to a stronger effect of rapeseed prices on wheat shares, but again did not affect barley shares.     

Measuring value creation and appropriation in firms: The VCA model

Research summary : Using a productivity technique (VCA model), we estimate the economic value created by a firm and appropriated by its stakeholders in two specific empirical contexts. In the first application, we use publicly available data from the U.S. airline industry to illustrate how the VCA model can be used with multiple stakeholder groups. In the second application, we provide estimates for three global automobile companies (GM, Toyota and Nissan), showing how the model can be reformulated using value added. In both industries we find substantial heterogeneity among firms in the creation and distribution of value. We discuss strengths and limitations of the VCA model and implications for strategic management research. Managerial summary : Firms create value not only for shareholders, but also for other stakeholders, including employees, customers and suppliers. This article applies a method to quantify the “new” economic value created by a firm over an interval of time; the method also reveals the distribution of that value among the stakeholders. The proposed method gives managers some means to assess changes in the economic value created and distributed. We find that the creation and distribution of value has varied greatly among major U.S. airlines and global automakers in recent decades. Moreover, returns to shareholders typically accounted for only a small proportion of firms' total value creation and often had little relation to broader changes in the magnitude and distribution of value.
