Managerial ability and bank‐loan pricing

This paper examines the impact of borrowers’ managerial ability on lenders’ bank‐loan pricing and the channels through which managerial ability affects bank‐loan pricing. Using a large sample of US bank loans, we provide evidence that higher managerial ability is associated with lower bank‐loan prices. This effect is stronger in firms with high information risk, suggesting that an important channel for managerial ability to affect bank‐loan pricing is through improved financial disclosure to mitigate information asymmetry. The relationship is also stronger for firms with weak business fundamentals, implying that another channel is through improved business performance. Of these two mechanisms, path analysis suggests that the business‐fundamentals mechanism is the more important channel through which managerial ability affects bank‐loan pricing.     

Processes of normal inverse Gaussian type

With the aim of modelling key stylized features of observational series from finance and turbulence a number of stochastic processes with normal inverse Gaussian marginals and various types of dependence structures are discussed. Ornstein-Uhlenbeck type processes, superpositions of such processes and stochastic volatility models in one and more dimensions are considered in particular, and some discussion is given of the feasibility of making likelihood inference for these models.     

The Use of Data Envelopment Analysis with Probabilistic Assurance Regions for Measuring Hospital Efficiency

This paper uses Data Envelopment Analysis (DEA) for an estimation of the cost efficiency of 70 Danish hospitals. The analysis relates to a cost function based on 483 outputs in combination with a set of probabilistic assurance regions defined by the cost distributions for each output. It is demonstrated that the probabilistic assurance region approach allows for (i) a frontier estimation in the full output space, i.e., no fixed aggregation is required, and (ii) a controlling of the variation in heterogeneity of the output clusters, in casu Diagnosis Related Groups. The likelihood of the estimated efficiency score for a given hospital can be measured based on the sensitivity of the score w.r.t. the probability levels used in the specification of confidence intervals for the probabilistic assurance regions.     

Wie kann wissenschaftliche Politikberatung zu besserer Politik beitragen?

Wissenschaftliche Beratung kann der Politik wichtige Hinweise zur effektiven Probleml?sung liefern und zur Legitimation institutioneller Reformen beitragen, die potenziell strittig sind. Welche Formen der Politikberatung gibt es in Deutschland? Inwieweit war die Politikberatung erfolgreich, wo liegen ihre Defizite und wie k?nnte sie effizienter gestaltet werden?     

New marketing channels for food quality products in Norway

Marketing is an important and challenging competitive instrument for small-scale quality food producers. Traditional commercial channels may be unprofitable and small-scale food producers often lack access to a highly concentrated retail sector. In this situation a number of strategic alliances between farmers and between farmers and other public and private actors have emerged. The aim of this paper is to discuss and compare initiatives to develop alternative marketing channels for small-scale specialty food producers. The three examples of emerging channels we investigate are (i) the 'new' farmers markets, (ii) retail initiatives where local producers deliver their produce directly to shops, and (iii) companies founded by large cooperatives to market specialty products. Recent research has justified that such initiatives can be conceptualized as hybrid governance structures, i.e. complex structures that entail properties of both market and hierarchy. We pay particular attention to the problem of quality enforcement in emerging marketing channels.     

玩转口碑营销

一旦消费者决定购买一项产品,他们会首先确定经过产品体验、推荐或打知名度的营销活动而筛选出的一组初选品牌。在消费者收集来自各种渠道的产品信息并决定购买何种产品的过程中,他们会对这些以及其他品牌进行积极评估。然后,他们的售后体验会为他们的下一次购买决策提供依据。尽管在这一过程的各个阶段,     

Bundling and Unbundling in Public–Private Partnerships: Implications for Risk Sharing in Urban Transport Projects

Public–private partnership (PPP) projects may be organized in a variety of ways, depending on the level of integration of the so‐called Special Purpose Vehicle. Based on the analyses of four major PPP light rail projects in Spain, this article outlines two fundamentally different models of organizing the Special Purpose Vehicle in PPP projects; moreover, the article examines the central principles of these two different models of organizing the private sector Special Purpose Vehicle and their implications for risk sharing and project management in large‐scale infrastructure PPP projects.
