Russia has so far failed to achieve its goal of monetary integration into the international capital markets. Due to the deep financial and currency crisis which began in 1998, the current situation is a far more difficult one than in 1991, at the start of the transformation process. The following article examines the reasons why this situation arose and formulates alternatives to the reform approaches to date. 相似文献

Competences for green development and leapfrogging in Newly Industrializing Countries are becoming increasingly urgent from a global perspective. The integration of these innovations into the development process in the rapidly growing economies requires knowledge build-up and technology cooperation. The prospect of exporting sustainability technologies can add an incentive for them to move towards sustainability technologies. These issues also affect innovations to increase material efficiency, which are receiving increasing interest among sustainability innovations. The competences for green development are analyzed with an innovation indicator approach. The general innovation capabilities are evaluated using R&D indicators and survey results about general innovation capabilities. Technological competences in the sustainability fields are a key indicator for the absorptive capacity of sustainability technologies and for the ability to export them. International patents and publications, and successes in foreign trade indicate to what extent a country is already able to participate in global technology markets. The resulting pattern shows various strengths and weaknesses of the analyzed countries. In general, the knowledge build up in material efficiency strategies is above-average in the Newly Industrializing Countries. There is a strong need for strategic positioning of the countries and for coordination of the various policy fields involved. 相似文献

The economic implications of the latest upsurge of the oil prices for the whole world—and for the developing countries in particular—are such as to make a strategy of common responsibility of industrialized and developing countries more urgent than ever. Rainer Offergeld, Federal Minister for Economic Cooperation, elucidates his ideas about such a strategy. 相似文献

Socioemotional Wealth and Innovativeness in Small‐ and Medium‐Sized Family Enterprises: A Configuration Approach 下载免费PDF全文
What makes small‐ and medium‐sized family firms (family SMEs) innovative? Some family firm dynamics promote, yet others hinder innovation. It remains unclear whether combinations of family firm dynamics increase innovativeness. Our configurational perspective of socioemotional wealth (SEW) unravels determinants of family SMEs' innovativeness. We conduct a fuzzy set qualitative comparative analysis with 452 Swiss family SMEs. We categorize SEW dimensions into configurations of necessary and sufficient conditions. We contribute to theory on family SMEs' innovativeness because we reveal that the interplay of SEW dimensions leads to innovativeness. This offers practitioners a better framework to choose between SEW configurations. 相似文献

Starting from the one-dimensional results by Wang et al (1994) we consider the performance of the ordinary least squares estimator in comparison to the best linear unbiased estimator under an error component model with random effects in units and time. Upper bounds are derived for the first-order approximation to the difference between both estimators and for the spectral norm of the difference between their dispersion matrices. 相似文献

Engineering Process Controllers (EPC) are frequently based on parametrized models. If process conditions change, the parameter estimates used by the controllers may become biased, and the quality characteristics will be affected. To detect such changes it is adequate to use Statistical Process Control (SPC) methods. The run length statistic is commonly used to describe the performance of an SPC chart. This paper develops approximations for the first two moments of the run length distribution of a one-sided Shewhart chart used to detect two types of process changes in a system that is regulated by a given EPC scheme: i) changes in the level parameter; ii) changes in the drift parameter. If the drift parameter shifts, it is further assumed that the form of the drift process changes from a linear trend under white noise (the in-control drift model) into a random walk with drift model. Two different approximations for the run length moments are presented and their accuracy is numerically analyzed. Received: August 1998 相似文献

The claims that value-based management (VBM) increases corporate performance have attracted considerable interest among researchers and organizations over the last three decades. Even though many studies have been conducted, the evidence on whether users outperform non-users is inconsistent. This paper attempts to place these diverse findings into perspective, and provide venues for future research. For that purpose, we drafted a framework to analyze 120 empirical studies on VBM. We concluded that meaningful hypothesis tests have been impaired by the narrow scope of data sets as well as methodological misspecifications. Based on this analysis, we categorized studies into four streams of research, employing factor analysis and cluster analysis. We then suggested that the most sophisticated studies identified positive performance effects of VBM. Lastly, we derived guidelines to improve the hypothesis testing of future studies on VBM. 相似文献
