There is a growing body of literature that suggests that advanced economies are experiencing an economic restructuring such that the engines of economic development are smaller, more independent, firms acting in an increasingly cooperative manner. In assessing whether the UK economy is actually experiencing such a shift in inter-firm relations, the paper firstly assesses the existing evidence. This evidence suggests the continued dominance of large firms and only limited and uneven movements away from a low-trust system. Secondly, the paper presents evidence on the nature of inter-firm relations in the UK engineering construction industry in the 1980s and 1990s. the research shows considerable improvement in performance against schedule associated with the emergence of management contractors. Management contractors can improve performance either by adopting a high-trust route in which they seek to make overall efficiency gains by integrating design and construction, or by adopting a low-trust route in which they seek to reduce scope for opportunism by rigidifying design, and by passing on risk. Evidence is presented which shows that management contractors in the UK have so far predominantly adopted the low-trust route to improved performance. Cumulatively, the evidence suggests the dominance of the ‘top down’ control of inter-firm relations in the UK.  相似文献

Long memory in volatilities of German stock returns   总被引:3,自引:0,他引:3  
We show that there is strong evidence of long-range dependence in the volatilities of several German stock returns. This will be done by applying a method using the difference of the classical log-periodogram regression estimator for the memory parameter and of the tapered periodogram based estimator. Both estimators give similar values for the memory parameter for each series and this indicates long memory. To support our findings we apply also a methodology using the sample variance and a wavelet based estimator to the data. Also these two methods show clear evidence of long-range dependence in the volatilities of German stock returns.First version received: December 2001/Final version received: March 2003The computational assistance of Eleni Mitropoulou and Björn Stollenwerck as well as the helpful comments of two unknown referees are gratefully acknowledged.

ABSTRACT

In this paper a novel information model that can be used in Manufacturing Execution Systems is presented. The model is based on the fusion of ISA95, AML and OPC UA. ISA95 is used to define, unify and describe the details of a product and production technology. It also enables communication with ERP systems. The AML standard allows information about the production facilities to be presented. The OPC UA address space represents different parts of an information model while the OPC communication protocol enables it to be linked to actual production systems. The proposed concept is illustrated using an actual example of a production line for electronic devices.  相似文献

Monetary policy and financial markets are intrinsically linked. Central banks conduct monetary policy by influencing financial market prices. Financial market prices reflect the expectations of market participants about future economic and monetary developments. Monetary policy works primarily through expectations. Transparency and credibility render monetary policy more effective. However, they are no substitutes for action. If a credible central bank uses words with the explicit aim of substituting them for action, it will risk losing credibility. To avoid what has been described as “the dog chasing its tail” problem, central banks must exercise caution in basing their monetary policy decisions on financial market information. The information about expected future developments reflected in market prices must be continuously cross-checked against economic and monetary indicators in what amounts to a “checks and balances” approach to monetary policy.  相似文献

Intellectual property infringements rank among the top economic crimes, even though there are mechanisms in place to prevent their occurrence. One such mechanism are nondisclosure agreements, which, however, have been reported to fail in practice. This article argues that this may be overcome by strengthening employees’ concept learning. In an experiment, we investigated whether extended nondisclosure agreements, which provide the employee with detailed explanations and examples, lead to better recognition of trade secrets as compared to a standard nondisclosure agreement or no agreement at all. It was found that the extended nondisclosure agreement indeed increased participants’ ability to judge what falls under the trade secret law, whereas the standard nondisclosure agreement showed no such effect. Furthermore, the effects of the factors ‘Involvement’, ‘Specificity’, ‘Publicity’, and ‘Purpose’ on the identification of trade secrets could be proven experimentally. Employees’ judgments of whether an information represents a trade secret seem to rely on general cognitive processes. From this follows that concept learning could be integrated into systematic approaches for protecting intellectual property.  相似文献

In this paper we offer a bootstrap‐based version of the Cox specification test for non‐nested hypothesis to discriminate between ESTAR and MSAR models. Both models are commonly used for modeling real exchange rates dynamics. We show that the test has good size and power properties in finite samples. In an application, we analyze several major real exchange rates to shed light on the question of which model describes these processes best. This allows us to draw conclusions about the driving forces of real exchange rates. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
