Strategic alignment and performance: Brazilian companies in the medical diagnostics sector

A gap has been identified in the literature on the diagnosis and monitoring of the degree of strategic alignment. The main objective of this article is to diagnose and analyze the strategic alignment profile using the alignment diagnostic profile (ADP) tool, which enables organizations to show visually their degree of strategic alignment. The methodological approach adopted is multiple-case studies, which were conducted at five organizations in the medical diagnostics sector. The results indicate that the ADP enables organizations to understand the steps required to improve their level of alignment and to identify and locate gaps and conflicts.     

Price signatures

Price signatures are statistical measurements that aim to detect systematic patterns in price dynamics localised around the point of trade execution. They are particularly useful in electronic trading because they uncover market dynamics, strategy characteristics, implicit execution costs, or counter-party trading behaviours that are often hard to identify, in part due to the vast amounts of data involved and the typically low signal to noise ratio. Because the signature summarises price dynamics over a specified time interval, it constitutes a curve (rather than a point estimate) and because of potential overlap in the price paths it has a non-trivial dependence structure which complicates statistical inference. In this paper, I show how recent advances in functional data analysis can be applied to study the properties of these signatures. To account for data dependence, I analyse and develop resampling-based bootstrap methodologies that enable reliable statistical inference and hypothesis testing. I illustrate the power of this approach using a number of case studies taken from a live trading environment in the over-the-counter currency market. I demonstrate that functional data analysis of price signatures can be used to distinguish between internalising and externalising liquidity providers in a highly effective data driven manner. This in turn can help traders to selectively engage with liquidity providers whose risk management style best aligns with their execution objectives.

De-internationalization through the lens of intellectual property rights

Many studies have focused on internationalization, with few shedding light on de-internationalization. In this article, we contended that de-internationalization is common in a world of matured globalization, yet it remains underexplored. We sought to build on the seminal articles on de-internationalization by extending our understanding of the concept from a voluntary to an involuntary perspective. In particular, we used intellectual property rights as an institutional coercive dimension and set theory as a discerning mechanism to enrich our understanding of de-internationalization. Our article, which demonstrates the multi-faceted conditions of de-internationalization, should benefit formal institutions and policy makers in developing a greater understanding of the relationship between public policies and focal firms' decisions to de-internationalize. We also hope that our article will contribute to greater visibility of de-internationalization and make the concept more approachable to our international business audience.     

南北城市功能差异与南北经济差距

文章从中心城市增长极作用差异的视角,探讨了我国南北方经济差距扩大的成因和作用机制。理论研究发现,在中国城市发展过程中,南方中心城市的创新能力及其对周围地区的辐射带动能力较强,北方中心城市的创新能力和辐射带动能力则相对较弱,这种南北中心城市极化作用差异是导致南北经济差距扩大的重要原因。而南北中心城市极化作用的差异很大程度上受到城市形成机制的影响,南方地区更多地依靠市场机制主导形成城市,中心城市与周围地区构成了一个经济有机体;北方地区的城市则更多依靠行政机制向周围吸取资源,形成了一个资源向中心城市单向流动的资源堆。这种不同的城市形成机制塑造了南北中心城市的功能差异,最终导致南北经济差距不断扩大。基于2008-2018年城市面板数据的经验研究表明,南北中心城市存在显著的极化作用差异,而这种极化作用差异对南北经济差距具有显著影响,中心城市的辐射带动能力和创新能力越强的地区经济增长率越高。进一步研究发现,城市形成机制是影响南北中心城市功能差异和南北经济差距的重要机制,越是依靠市场机制形成和扩大中心城市的地区,其中心城市的辐射带动能力和创新能力越强,从而越有利于促进地区整体的经济增长。     

The evolvement of momentum effects in China: Evidence from functional data analysis

Using an approach based on functional data analysis, we address the controversy that momentum or reversal effect disputes exist in China’s A-shares markets. It finds patterns of nonlinear cross-sectional variation and the dynamic change of average stock returns over time. After the global financial crisis of 2008, our empirical results show that momentum effects in the middle term went away and reversal effects took over. We also find substantial reversal effects for the short- (1-6 months) and long-term (3 years), respectively, but no evidence of permanent momentum effects in China.     

The use of information technology for international transfer pricing in multinational enterprises

This paper studies the degree to which multinational enterprises (MNEs) use information technology for managing international transfer pricing (ITP). Based on 21 interviews conducted with in-house accounting and tax professionals in MNEs, we observed limited use of information technology for ITP management. However, some degree of ITP automation was observed in workflow management to produce transfer pricing documentation. The limited degree of automation observed was driven by both system- and individual-level barriers. Overall, we found that management accountants and information technology experts dominate the enterprise resource planning system design agenda, and the tax departments’ ITP tax compliance objective plays a relatively limited role. This reduces the ability for ITP automation partly because the data segmentation that is prioritized for management reporting does not support the tax departments’ needs for legal-entity data segmentation to document tax compliance.     

Innovation ecosystems as a service: Exploring the dynamics between corporates & start-ups in the context of a corporate coworking space

The desire to create innovative organizational spaces has led to various instantiations of innovation ecosystems. Towards this direction, there is a growing interest in establishing corporate innovation ecosystems in the form of ‘corporate coworking spaces’ (CWS). From a relational ontological standpoint, this study builds on the collaborative spaces literature with the aim to investigate the emerging dynamics between corporates and start-ups in an innovation ecosystem. Through an abductive research strategy (ARS) as well as service design methods, we explore how co-creation between corporates and start-ups emerges (or not) in an innovation ecosystem that serves as a collaborative space in Denmark. Our empirical findings challenge the mostly overenthusiastic connotations and thus the study contributes to the critical coworking research stream. More specifically, we give emphasis on the co-constructive entanglement of socio-spatial arrangements and we propose a framework for revisiting the design of CWS through 1) balancing the engineered and evolving parts of the ecosystem, 2) facilitating stakeholder alignment, 3) adopting a service-oriented approach and 4) developing inclusive strategies. Apart from the implications for scholars and practitioners who study and design CWS, we argue that future research would especially benefit from building on a service-oriented approach of innovation ecosystems and we call for more interdisciplinary research.
