Determinanten des deutschen Kreditzinsniveaus

Seit Mitte der 90er Jahre liegt das deutsche Kreditzinsniveau über dem Durchschnitt der EWU. Worauf ist diese Entwicklung zurückzuführen? Sind die deutschen Banken weniger effizient? Liegt der Zinsunterschied an den hohen Refinanzierungskosten? Gibt es in Deutschland mehr Kreditausf?lle, oder sch?tzen die deutschen Banken die Risiken realistischer ein? Dr. Stefan Sch?fer, 34, und Christian Weistroffer, 30, Dipl.-Wirtschaftsingenieur, arbeiten im Referat Banken, Finanzm?rkte und Regulierung von Deutsche Bank Research; Christian Weistroffer forscht au?erdem am Center for Financial Studies, Frankfurt am Main. * Der Beitrag gibt die Meinung der beiden Autoren, aber nicht unbedingt diejenige des Center for Financial Studies oder von Deutsche Bank Research wieder.     

Electronic Commerce and the Future for SMEs in a Global Market-Place: Networking and Public Policies

This paper explores three inter-related issues: globalisation; the role of small and medium sized enterprises (SMEs); and electronic commerce (e-commerce). A central question is whether e-commerce offers advantages to SMEs that may facilitate their access to global markets and help them overcome the disadvantages they face vis-à-vis large transnational corporations (TNCs)? The paper starts by briefly considering the extent of globalisation and its relationship to free trade. We then go on to consider recent developments in e-commerce, focusing on the key issue of e-payment systems. Differences in the requirements of large and smaller firms are identified, and we identify a number of key issues concerning access of smaller firms to e-payment systems and the (virtual) market place, and outline their implications for regulatory policy. Our analysis highlights the importance of network externalities, and institutional factors affecting trust and the relationships amongst different economic actors. This leads to a consideration of networking and public policies more broadly. One of the central conclusions of our analysis is that there are important synergies between e-commerce (virtual) networks and (real) production networks. This suggests that policy makers and smaller firms should think in terms of extending existing, and catalysing new, real production networks to incorporate e-payment systems for networks of firms in order to facilitate their access to virtual markets.

     

Longitudinal satisfaction measurement using latent growth curve models and extensions

Latent growth curve modeling (LGCM) is used to describe changing latent aspects over time manifested in observed indicators. A case study of satisfaction indicators of cinema visitors observed over 12 months is used to detect such transitions from excitement factors to performance factors to basic factors, as mentioned in the Kano-model. The sample is split up into groups depending on slope trajectories and intercepts. More precisely, a growth mixture model (GMM) with random slopes and random intercepts is incorporated offering the possibility of visualizations including individual intercept and slope values. This figure allows deeper insight into the modifications of time.     

The Corn–Guano Model

The model presented here can be seen as an extension, specifically designed to deal with the issue of exhaustible resources, of the well‐known ‘corn model’. We believe that useful insights are obtained by concentrating on a benchmark case, that of an economy with only one reproducible ‘good’, corn, and only one ‘resource’, guano. The corn–guano model aims at delineating some major issues related to the introduction of exhaustible resources within a post‐Sraffian model. In this paper we concentrate on the dynamics of the price variables. The ultimate goal concerns more generally the treatment of intertemporal economies outside a regular growth path, i.e. it concerns the degree of generality of the post‐Sraffian theory itself.     

Entrepreneurial personalities in political leadership

Societies around the globe respond to the contemporary technological and economic change by defining entrepreneurship and innovation as core principles for future competitive advantage. Does this rise of the “entrepreneurial society” also imply that entrepreneurial personalities are becoming increasingly widespread and powerful in political leadership? Joseph A. Schumpeter already argued that highly influential entrepreneurs are unique and show a certain personality pattern that can be described as being not only high in creativity and change orientation but also high in competitiveness and rule-breaking. It is interesting to ask whether such Schumpeterian personalities indeed play an increasingly important role in political leadership, given that daily routines of policy leaders, at least at first glance, usually require rather non-entrepreneurial strategies such as careful, risk-averse diplomacy. To address this question, we first survey the existing literature on personality and political leadership. We further present a novel personality analysis of an influential business leader that recently made a transition to political leadership: Donald J. Trump, the incumbent US president. Employing a language-based, computerized method of analyzing Twitter statements, we compare his online personality to the online personality of other influential entrepreneurs and business managers, who do not engage in political leadership. The results indicate that Trump is indeed distinct in that he shows stronger features of a Schumpeterian personality. However, he is also comparatively high in Neuroticism. We discuss these findings focusing on the potential implications of a concentration of entrepreneurial mindsets in political leadership.     

入美企业如何避开国家安全限制

2008年11月14日,美国财政部发布《2007年外国投资与国家安全法》（FINSA）的实施细则,此项法律旨在改革美国外国投资委员会（CFIUS）关于国外机构收购、兼并和接管美国企业国家安全审查体制。2008年12月,美国财政部发布了有关经过CFIUS审核认为存在国 家安全问题的交易类别指引,正式条例和相关指引传递的明确信息是,在个案基础上,CFIUS将保持其对外国投资交易进行国家安全审查的广泛自由裁量权。那么,美国这些法规的出台将会给我国企业以外资并购的方式进入美国市场带来怎样的影响？
