A theory of leadership is proposed and tested. Leaders perform many roles in a firm. They become leaders because they succeed at these tasks more than others and at least some of their successes are visible. The theory implies that leaders tend to be more able, place themselves in visible decision making situations more frequently and are generalists. Also, the most able leaders should be found in the highest variance industries, where decision making has the greatest payoff. The theory is tested using data on Stanford alumni and is confirmed. Leaders are generalists rather than specialists, both innately and in their pattern of skill acquisition. 相似文献

In the paper “Networks and geography in the economics of knowledge flows” Maggioni and Uberti provide a rich and detailed
overview of the current state-of-art and future challenges of the analysis of knowledge flows in economics. Maggioni and Uberti
illustrate how geographical factors and network factors can explain spatial patterns of knowledge flows. This commentary portrays
where the type of studies discussed by the authors fit in the wider literature on geography, networks and knowledge flows.
Second, the commentary discusses the suggestions of future research the authors describe and proposes some further avenues
for future research that are in line with those suggested by the authors. In particular, it zooms in onto the role of comparative
statics in studies of network dynamics, stochastic estimation models of network evolution and content-based network analysis
in pushing the frontier of research on networks, geography and knowledge flows. 相似文献

The paper reconstructs the Veblenian critique of the pecuniary economy from the perspective of Niklas Luhmann's theory of autopoietic social systems. Luhmann argued that social systems relieve people from the overwhelming civilizational complexity, but develop autopoietic properties hindering rational solutions to human problems. This argument allows seeing the pecuniary economy as an important complexity-reducing device, which, however, develops excessive autonomy from the embedding societal and ecological environment. For this reason, like other autopoietic systems, the economy has a high chance of becoming societally and ecologically unsustainable. While Veblen criticized the obsession of classical economics with equilibrium and the natural order, Luhmann urged to replace the notion of equilibrium with that of autopoiesis, which focuses attention on the sustainability problem. Accentuating this problem is shown to be the main evolutionary economics implication of Luhmann's work. 相似文献

We measure productivity in leading edge economic research by using data envelopment analysis (DEA) for a sample of 21 countries belonging to the Organization for Economic Cooperation and Development (OECD). Publications in ten top journals of economics from 1980 to 1998 are taken as the research output. Inputs are measured by R&D expenditure, the number of universities with economics departments and (as an uncontrollable variable) population. Under constant returns-to-scale, the US emerges as the only efficient country. Under variable returns-to-scale, the efficiency frontier is defined by the US, Ireland and New Zealand. With the exception of the US, all countries in our sample display increasing returns-to-scale, and thus have the potential to raise their efficiency by scaling up their research activities. 相似文献

互联网3.0时代的平台经济模式与发展策略 总被引:1,自引:0,他引:1
以平台企业为主体,以云计算、区块链等智能技术为支撑的平台生态系统可以高效且规模化地匹配零散需求与供给,成为互联网经济时代下所有经济活动和经济关系的总和,即平台经济。平台经济有利于创造多元商业模式,提升经济运转效率。但平台经济收益是非线性的,具有网络效应且极易形成市场垄断,对监管造成极大困难;平台经济模式的非对称议价行为使平台客户权益难以保护。由此,分别从企业平台化转型和政府监管两个维度提出了具体发展策略:选择合适的平台经济模式,变革传统组织架构,培养平台经济模式下的新技能;鼓励平台经济发展,以协同理念对平台经济进行全方位监管。 相似文献

These days, road safety has become a major concern in most modern societies. In this respect, the determination of road locations that are more dangerous than others (black spots or also called sites with promise) can help in better scheduling road safety policies. The present paper proposes a multivariate model to identify and rank sites according to their total expected cost to the society. Bayesian estimation of the model via a Markov Chain Monte Carlo approach is discussed in this paper. To illustrate the proposed model, accident data from 23,184 accident locations in Flanders (Belgium) are used and a cost function proposed by the European Transport Safety Council is adopted to illustrate the model. It is shown in the paper that the model produces insightful results that can help policy makers in prioritizing road infrastructure investments. 相似文献

The change from a centrally planned economy into a market economy is likely to have created a unique situation in economic history. Consequently, no existing economy theory is able to depict the process of transformation. It is argued in this paper that a Kaleckian theoretical approach may provide a starting point for the analysis of the formerly centrally planned economies of Central and Eastern Europe. This approach is applied to Hungary, within the framework of a computable general equilibrium model. A number of policy measures, such as wage constraint, devaluation and mark-up reduction, are considered and their effects on production, inflation and income distribution assessed. 相似文献

Cluster emergence is an important topic but weakly conceptualized in the literature. Focusing on the interaction of the local knowledge pool and firm growth, the paper develops a comprehensive framework to understand cluster emergence. In the framework, the cluster formation process starts with the collision of local and external knowledge which generates an innovation and stimulates the creation of local pioneering firms in a new field. To support the growth of follow-up entrants in the new industry, the local knowledge pool needs to be expanded and deepened through local knowledge sharing and external knowledge inflows. The enlarged local knowledge pool enables local firms to grow and explore other fields further. To promote cluster emergence, public policies need to facilitate the interaction of the local knowledge pool and firm growth. The paper illustrates the interactive framework with two aluminum extrusion clusters in China that emerged in different ways over different time periods. 相似文献

We examine the impact of product variety decisions on an operational measure – unit fill rate – and on sales performance. Results are estimated using weekly data over three years from 108 distribution centers of a major soft drink bottler. Our results show that fill rates are negatively associated with product variety at a diminishing rate. In addition, we examine the total effect of product variety on sales including both the direct effect and the indirect effect through operations performance. The total impact of product variety on sales initially is positive, although at a diminishing rate. However, beyond a certain level, increased product variety actually results in lower sales; that is, “too much of a good thing”. Thus, the findings provide a comprehensive understanding of the impact of product variety on operations and sales performance. 相似文献

Varieties of agents in agent-based computational economics: A historical and an interdisciplinary perspective 总被引:1,自引:0,他引:1

In this paper, we trace four origins of agent-based computational economics (ACE), namely, the markets origin, the cellular-automata origin, the tournaments origin, and the experiments origin. Along with this trace, we examine how these origins have motivated different concepts and designs of agents in ACE, which starts from the early work on simple programmed agents, randomly behaving agents, zero-intelligence agents, human-written programmed agents, autonomous agents, and empirically calibrated agents, and extends to the newly developing cognitive agents, psychological agents, and culturally sensitive agents. The review also shows that the intellectual ideas underlying these varieties of agents cross several disciplines, which may be considered as a part of a general attempt to study humans (and their behavior) with an integrated interdisciplinary foundation. 相似文献
