Global Sourcing Decision‐Making Processes: Politics,Intuition, and Procedural Rationality

Global sourcing (GS) is a firmly established phenomenon in modern business practice that requires specific expertise from different organizational functions, such as purchasing, production, logistics, and research and development to analyze and select sourcing alternatives effectively. In this context, global sourcing decision‐making (GSDM) processes pose major challenges because two dimensions of functional politics, namely goal misalignment and power imbalance across functions, appear to influence procedural rationality in a manner not understood to date. Likewise, intuition also seems to play a role for the procedural rationality of GSDM processes. To elucidate the conditions under which procedural rationality is hampered or enhanced by politics and intuition, we studied five cross‐functional GSDM processes, in front of extant strategic decision‐making literature. We derive formal propositions on how functional politics and intuition influence the procedural rationality and present contingencies for the divergent role of intuition as well as functional politics in GDSM processes. Our research contributes to existing GS literature by providing a theoretical model of important microfoundations of how GSDM processes evolve. The findings also guide managers on how to structure GSDM processes such that GS projects can be conducted in a more rational fashion.

从美国房价走势透视中国房地产市场走向

内容文章从量化分析的角度出发,研究了全美50个州和哥伦比亚特区房价指数序列的记忆性特征,发现各州房价指数序列均具有一定程度的长记忆性.同时,我们对50个州房价指数记忆参数的估计值进行了聚类分析,由此发现各州房价指数的记忆性呈现出一定的地区聚集性特征,而且还与地区的人口密度存在一定关系,从而为宏观政策制定者在决定房价调控措施的时候提供了有益的新思维,可使楼市更加健康稳定地发展.此外,文章的研究结果对于解决我国房地产市场目前存在的巨大泡沫问题提供了一个全新的视角     

Mix of Fiscal and Monetary Policy Rules and Inflation Dynamics in China

The present paper examines the role of the mix of fiscal and monetary policy rules in determining inflation dynamics using fiscal and monetary policy reaction functions and Markov‐switching vector autoregression methods based on quarterly data in the period 1992–2007. Our results show that fiscal and monetary policies in China can be adequately described using some simple rules, and that significant regime shifts took place around 1998. Fiscal policy tended to be active and countercyclical in the pre‐1998 period, then switched to be passive and more countercyclical, whereas monetary policy was characterized as passive and procyclical in the pre‐1998 period, and switched to be active and countercyclical afterwards. The mix of fiscal and monetary policy rules can explain inflation dynamics better than the monetary policy rule alone. Therefore, price stability requires not only appropriate monetary policy but also appropriate fiscal policy.     

Consumer workers as immaterial labour in the converging media markets: three value‐creation practices

This paper takes a practice‐based approach to consumer studies and focuses on the strategic and productive roles that consumers play as immaterial labour or consumer workers in the converging media markets. Based on a case study of a print media organization and its customers, the aim is to discuss the collaborative practices through which value is created in the market. By means of a textual analysis of online and interview data, three value‐creation practices are abstracted and illustrated: constructing a sense of belonging and collective identity, mutual helping and peer support, and building pride and self‐respect. Overall, the paper suggests that in global media environments, consumer‐customers are playing increasingly significant strategic roles in the practices and processes through which value is co‐created in the market. It is therefore concluded that the idea of consumers, and media audiences in particular, as recipients of communication and targets of marketing activities needs to be problematized and the dynamic strategic roles that consumers currently play in the market need to be acknowledged and actively incorporated into the business praxis of media corporations.     

Towards a Measure of Core Inflation using Singular Spectrum Analysis

This paper constructs a number of possible core measures of inflation using singular spectrum analysis (SSA). Annual changes in monthly inflation are decomposed into its trend, oscillatory and noise components in order to develop an understanding of the trend and cyclicality in South African headline inflation. Three cyclical components with differing amplitude and frequency are identified. The trend and cyclical components of inflation are found to be a good approximation of core inflation, the inertial part of inflation. These core measures are compared with other candidate core measures based on the properties of a good core inflation measure. Generally, the SSA measures outperform commonly used measures of core inflation based on both in‐ and out‐of‐sample performance.

Evaluating,Comparing, Monitoring,and Improving Representativeness of Survey Response Through R‐Indicators and Partial R‐Indicators

Non‐response is a common source of error in many surveys. Because surveys often are costly instruments, quality‐cost trade‐offs play a continuing role in the design and analysis of surveys. The advances of telephone, computers, and Internet all had and still have considerable impact on the design of surveys. Recently, a strong focus on methods for survey data collection monitoring and tailoring has emerged as a new paradigm to efficiently reduce non‐response error. Paradata and adaptive survey designs are key words in these new developments. Prerequisites to evaluating, comparing, monitoring, and improving quality of survey response are a conceptual framework for representative survey response, indicators to measure deviations thereof, and indicators to identify subpopulations that need increased effort. In this paper, we present an overview of representativeness indicators or R‐indicators that are fit for these purposes. We give several examples and provide guidelines for their use in practice.     

Open Variety Rights: Rethinking the Commodification of Plants

Open Variety Rights refer to the removal of the conditions attached to the usage of plants in agriculture, and to an analogy with open licensing in informatics that is notably different from the one that is taking shape at the intersection of the life sciences and informatics. This paper argues for the open licensing of plants as part of a response to the commodification of DNA; rather than a singular focus on farming or source code, this implies an analogy that aims at the removal of restrictions, whether as seeds, biodiversity, genetic sequences or DNA in informatics formats. First, the commodification of plants will be conceptualized. Second, the proposal for open licensing for varieties of crops will be discussed. Third, examples of the introduction of open licensing in the life sciences will be examined in relation to the potential to reformulate the definition of ‘openness’ to support those who wish to live and work with plants on their own terms.
