Are more resources always better for growth? Resource stickiness in market and product expansion

We examine how managerial growth logics combine with financial and human resource slack to influence the short‐term revenue growth of a sample of 112 manufacturing firms drawn from a unique database provided by the Ewing Marion Kauffman Foundation. Our results provide evidence that firms pursuing product expansion logics generally grow more slowly than firms that are not expanding their product base, but that financial slack positively moderates this relationship. We also find that human resource slack enhances short‐term market expansion, but slows down short‐term product expansion. We discuss the implications of these results for resource‐based views of growth. Copyright © 2004 John Wiley & Sons, Ltd.

质量成本收益分析

质量活动与财务业绩之间似乎不相关现象越来越明显。关于质量成本的讨论也慢慢淡出人们的视线。在管理会计行业中ROQ(ReturnonQuality)这一思想在美国却越来越受到关注。寻找质量活动与财务业绩之间正在失去的相关性成为目前一个重要的课题。本文在明确ROQ特征的基础上,从ROQ的角度,探讨质量活动与财务业绩的关系。     

Takeover activity in Australia: endogenous and exogenous influences

The present paper analyses the population of takeover bids for listed Australian companies using quarterly data over a 25-year period to re-examine the predictability of takeover activity and to determine if there is a flow on impact on macroeconomic variables. We examine whether takeover activity: (i) is endogenous; that is, determined by own activity; (ii) is jointly determined by macroeconomic and capital market variables; and (iii) has an exogenous spillover impact across the economy. We find that stock prices and takeover activity share a long-term common trend, the relative success of takeover bids is independent of sharemarket activity, and conclude that aggregate takeover activity is driven by fundamental economic factors rather than by speculative activity.     

The moderating influence of strategic orientation on the strategy formation capability–performance relationship

An effective strategy formation capability is a complex organizational resource—a dynamic capability that should lead to superior performance. Strategy scholars have examined the strategy formation capability from many perspectives. However, no study has examined a comprehensive model of strategy formation in the context of the firm's strategic orientation. We develop and examine such a model. The results show that strategic orientation moderates the relationship between different elements of the strategy formation capability and performance. Copyright © 2006 John Wiley & Sons, Ltd.

Evolving densities in continuous strategy games through particle simulations

Many cases of strategic interaction between agents involve a continuous set of choices. It is natural to model these problems as continuous space games. Consequently, the population of agents playing the game will be represented with a density function defined over the continuous set of strategy choices. Simulating evolutionary dynamics on continuous strategy spaces is a challenging problem. The classic approach of discretizing the strategy space is ineffective for multidimensional strategy spaces. We present a principled approach to simulation of adaptive dynamics in continuous space games using sequential Monte Carlo methods. Sequential Monte Carlo methods use a set of weighted random samples, also named particles to represent density functions over multidimensional spaces. Sequential Monte Carlo methods provide computationally efficient ways of computing the evolution of probability density functions. We employ resampling and smoothing steps to prevent particle degeneration problem associated with particle estimates. The resulting algorithm can be interpreted as an agent based simulation with elements of natural selection, regression to mean and mutation. We illustrate the performance of the proposed simulation technique using two examples: continuous version of the repeated prisoner dilemma game and evolution of bidding functions in first-price closed-bid auctions.     

Study on the Interior Market Network Structure and Its Efficiency in a Knowledge Based Company

A knowledge based company is the microcosmic foundation of the knowledge economy, the design of its organization structure should amplify the company competence to be agile to the knowledge elements. This paper expounds an interior market network structure which is fit for the company intellectual capital operation, and analyses this organization pattern about the reasons of existence, the effectiveness of growing up in scale, the economies of knowledge distribution and the efficiency of operation, and it will provide some beneficial theoretical guidance about how can a company improve its competition competence in the knowledge environment through organization innovation.
