Accounting practices and professional power dynamics during a crisis

This paper examines how changes in accounting practices during a crisis can affect organisational dynamics between hospital managers and clinicians. Our theoretical framework applies a multi-dimensional concept of power (Hardy, 1996) – which distinguishes power over resources, processes and meaning – to a longitudinal case study of a public university hospital during a budgetary crisis. Based on interviews with managers and clinicians, three successive time intervals with distinct power constellations are identified. Initially, we identify a pre-crisis phase where management formally controls resources, which seems to have limited effects on clinician dominance because managers lack ‘processual power’ and ‘power of meaning’. Next, an implantation phase emerges whereby the introduction of mandated budget cuts triggers shifts in the distribution of power, such that managers acquire power by securing the collaboration of clinicians – a phenomenon which has tangible benefits in terms of enabling budget compliance and increased service provision. Finally, the third phase may be conceptualized as a fiscal pressure regimen whereby, when budgetary pressures intensify further, management's newly gained ‘power of meaning’ is eroded because management are now seen to pursue unrealistic demands. Drawing on research insights gleaned during each phase, our analysis contributes to extant literature in at least three ways. First, we present novel findings regarding the impact of crises-related applications of accounting practices on intra-organisational power constellations. Second, our work highlights how accounting practices help shape the understanding of crisis, which, in turn, impacts the distribution of organizational power and influences intra-organizational patterns of collaboration. Third, we find that awareness of the meaning power of accounting practices can help shape strategic action in crisis situations.

Micro-level product-market dynamics: Shared knowledge and its relationship to market development

This work draws on consumer and psychology research to explain sociocognitive aspects of product-market dynamics at a higher level of specificity than prior research. The authors extend the field’s understanding of market-shaping shared knowledge through a theory-informed discussion of how shared product knowledge comes to exist and how it changes as product markets develop. They define shared knowledge as the aspects of product representations that are common across the minds of market actors, making it possible for them to understand one another. The authors also discuss ways to track shared knowledge content that is expressed in market narratives. As the characteristics of shared knowledge are explained and linked to stages of product-market development, the authors develop a set of researchable propositions to guide future research. The theoretical arguments and propositions in this article complement extant marketing strategy research by integrating individual-level consumer theory with market evolution models.

基于SD模型的客户服务成本信息不对称影响研究

制造企业经常通过提供高水平的客户服务向顾客传递优质产品质量信号,但由于客户服务成本信息不对称的影响,产品质量信号存在一定程度的失灵,影响了潜在客户对优质产品的购买。文章分析了制造企业客户服务成本不对称信息的原因及其对潜在客户购买行为的影响,通过建立系统动力学模型模拟产品销售过程,研究客户服务成本信息不对称度与企业客户数量之间的关系,结果表明客户服务成本信息不对称度下降有助于企业客户数量的增长,但其影响力有随时间下降的趋势。

Does Gibrat's Law hold among young,small firms?

According to Gibrat's Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the examined period. Aimed at extending this line of investigation, the present paper uses quantile regression techniques to test whether Gibrat's Law holds for new entrants in a given industry: that is for new small firms in the early stage of their life cycle. The main finding is that for some selected industries in Italian manufacturing Gibrat's Law fails to hold in the years immediately following start-up, when smaller firms have to rush in order to achieve a size large enough to enhance their likelihood of survival. Conversely, in subsequent years the patterns of growth of new smaller firms do not differ significantly from those of larger entrants, and the Law therefore cannot be rejected.JEL Classification: L11, L60Previous versions of this paper were presented at the 27th Annual EARIE Conference (Lausanne, 7-10 September 2000) and at seminars held between 2000 and 2003 at the Economics Department of Harvard University, the Catholic University of Milan, the University of Ferrara, the University of Bologna, the Bank of Italy, and Athens University of Economics & Business.

Evolution of trade patterns in the new EU member states

The paper analyses the evolution of the trade specialization pattern in the new EU member states. Relying on the empirical approach of the Markov transition matrices it analyses both the changes in the external shape of the distribution of comparative advantages and the intra‐distribution dynamics. The new members show a dynamic trade pattern: they gained comparative advantages relatively fast in sectors in which they were lagging behind at the beginning of the transition, notably in some ‘high tech’ products. In addition, many specialization improvements occurred in those items for which world demand expanded at the fastest rate over the nineties.     

Agglomeration in an innovative and differentiated industry with heterogeneous knowledge spillovers

This paper introduces an agent-based simulation model to study the technological development, the economic performance of firms and the evolution of agglomerations in a differentiated industry. The analysis is based on the interaction and behavior of firms, which might share knowledge but at the same time are competitors on the goods markets. Firms do not only compete with quantities they can also introduce process and product innovations. The level of knowledge of a firm describes the capabilities to perform innovations. Knowledge can be accumulated by investing in R&D and by knowledge spillover, which depend on geographical and technological proximity. Simulation runs show that there is an incentive to agglomerate in young industries and that geographical proximity enhances innovation, especially the number of product innovations.
