Towards a kernel theory of external knowledge integration for high-tech firms: Exploring a failed theory test

Designing information systems (ISs) requires a thorough understanding of the organizational knowledge processes in which these systems are used. Although much is known about internal organizational knowledge processes, the understanding of external knowledge processes is less developed. Hence, this paper reflects an attempt to operationalize and test a model of the process of external knowledge integration (EKI), consisting of an identification, acquisition, and utilization stage. We utilize high-technology based firms from a variety of high-tech categories including nanotechnology based firms since these firms have critical knowledge integration needs. The results of an international survey, with responses of 317 high-tech companies, suggest that not these three EKI-stages, but four organizational effectiveness functions (goal attainment, pattern maintenance, adaptation, and integration) account for most variation in responses. These findings seem to imply that ISs that are to support the EKI-process should be designed according to organizational effectiveness functions rather than to EKI-stages. It is proposed that each organizational effectiveness function imposes different requirements on ISs because users interact differently with IS in each function.     

资产证券化对货币政策实效性的影响

资产证券化对货币政策的影响 ,是一个具有理论和实际意义的重要问题。本文从三个方面对此进行了表述。一是资产证券化对货币政策传导路径的影响 ,指出它并未降低利率政策的实效性 ,但对货币供应量这一货币政策的中间目标的实效性会有影响。二是资产证券化对利率期限结构的影响 ,指出资产证券化加强了短期利率影响长期利率的实效性 ;三是分析了资产证券化对银行监管的影响。     

REIT Returns and Inflation: Perverse or Reverse Causality Effects?

Contrary to the Fisherian theory of interest, previous studies document a negative relationship between REIT (Real Estate Investment Trust) returns and inflation. In this research, we re-examine this perverse inflation behavior by testing for the causal relationships among REIT returns, real activity, monetary policy, and inflation through a vector error correction model. Our results indicate that the observations of REIT returns as perverse inflation hedges are spurious. The observed negative relationship between REIT returns and inflation is in fact a manifestation of the effects of changes in monetary policies. These findings are consistent with Darrat and Glascocks (1989) evidence of monetary effects on REIT returns.     

央行资本盒与货币政策的有效性

2007年次贷危机后,各国央行都承担起“最后贷款人”的职责,救助金融机构,央行自身资产负债表的质量不断恶化,引发对中央银行资本金的关注。央行在履行维持物价稳定和一些“准财政”职能时,资本金可能遭受损失,资本金的损失会影响到央行的公信力和独立性,以及货币政策的有效性。充足的央行资本金对于货币政策的有效执行来说是一种有力的保障。     

The Relationship Between REITs Returns and Inflation: A Vector Error Correction Approach

Previous studies show that REITs returns and inflation arenegatively related. This paper reexamines this perverse inflation hedgephenomenon by investigating the relationship among REITs returns, realactivities, monetary policy and inflation through a Vector ErrorCorrection Model. Empirical results show that inflation does notGranger-cause REITs returns and that REITs returns signal changes in monetary policy. The observed negative relationship between REITs returnsand inflation is merely a proxy for the more fundamental relationshipbetween REITs returns and other macroeconomic variables.
