Competition and Concentration in the New European Banking Landscape

This paper measures the degree of concentration and competition in the enlarged European Union (EU) banking environment over the period 1998–2002. In the empirical part we opt for a methodology as proposed by Panzar and Rosse based on a non‐structural estimation of market competition. Our results suggest that European banks were operating under conditions of monopolistic competition and that bank interest revenues in the 10 new EU member states was earned under conditions of higher competition than those that existed in the old EU banking countries. The opposite result was observed for total operating revenues. Smaller banks earn interest income in a less competitive environment than larger banks, while the opposite is observed for total revenues.     

Engaging the audience through videography as performance

ABSTRACT

The audience is an important part of videography, but its role tends to be seen as passive and unengaged. The audience’s experience is often guided in videography, with intended reaction made clear. Yet such an approach to the audience does not make use of the possibilities of videography for inciting active interaction and incorporating multiple interpretations. Previous research has suggested that videography has potential for interventional influence on audiences by taking on the performative turn in research. Developing more deeply the notions of performance and performativity in the context of videography, this paper proposes that one way to activate audiences, interact directly with them and engage them in meaning-making is to approach videography as performance. To provide practical suggestions for creating such performance, the paper contextualises videography as a recording medium, thus establishing its ontological position and ties to other media.     

New plant engineering techniques,R&D investment and international trade

New plant engineering techniques (NPETs) may significantly improve both production and quality of foods. Some consumers and regulators around the world might be reluctant to accept such products and the global market penetration of these products may remain low. We develop a parsimonious economic model for R&D investment in food innovations to identify conditions under which NPET technology emerges in the context of international trade. The framework integrates consumers' willingness to pay (WTP) for the new food, the uncertainty of R&D processes, the associated regulatory cost of approval, and the competition between domestic and foreign products. With generic applicability, the model enables the quantitative analysis of new foods that could be introduced in markets and then traded across borders. We apply the framework to a hypothetical case of apples improved with NPETs. Simulation results suggest that import bans and high values of sunk cost can reduce R&D investment in NPETs to suboptimal levels.     

Energy balance climate models and general equilibrium optimal mitigation policies

In a general equilibrium model of the world economy, we develop a two-dimensional energy balance climate model featuring heat diffusion and anthropogenic forcing driven by global fossil fuel use across the sphere of the Earth. This introduces an endogenous location dependent temperature function, driving spatial characteristics, in terms of location dependent damages resulting from local temperature anomalies into the standard climate-economy framework. We solve the social planner's problem and characterize the competitive equilibrium for two polar cases differentiated by the degree of market integration. We define optimal taxes on fossil fuel use and how they may implement the planning solution. Our results suggest that if the implementation of international transfers across latitudes is not possible then optimal taxes are in general spatially non-homogeneous and may be lower at poorer latitudes. The degree of spatial differentiation of optimal taxes depends on heat transportation. By employing the properties of the spatial model, we show by numerical simulations how the impact of thermal transport across latitudes on welfare can be studied.     

A play-the-winner-type urn design with reduced variability

We propose a new adaptive allocation rule, the drop-the-loser, that randomizes subjects in the course of a trial comparing treatments with dichotomous outcomes. The rule tends to assign more patients to better treatments with the same limiting proportion as the randomized play-the-winner rule. The new design has significantly less variable allocation proportion than the randomized play-the-winner rule. Decrease in variability translates into a gain in statistical power. For some values of success probabilities the drop-the-loser rule has a double advantage over conventional equal allocation in that it has better power and assigns more subjects to the better treatment.

The Impact of Corporate Social Responsibility Disclosure on Corporate Reputation: A Non-professional Stakeholder Perspective

This paper examines the impact of corporate social responsibility (CSR) disclosure on corporate reputation as perceived by non-professional stakeholders. Proponents of CSR disclosure argue that CSR disclosure can be considered as a tool for reputation management. We empirically investigate this claim using a reputation index which tracks the general public’s perceptions of corporate reputation over time. In our analysis, we focus on disclosure in stand-alone CSR reports and control for CSR performance. We find that, in contrast to the common belief, stand-alone CSR reports do not influence corporate reputation among non-professional stakeholders. However, we are able to document that stand-alone CSR reports influence corporate reputation among professional stakeholders. We also provide some evidence that transparent CSR disclosure on corporate websites can influence corporate reputation among non-professional stakeholders.

Imputing relevant information from multi-day GPS tracers for retail planning and management using data fusion and context-sensitive learning

It is well known that the right location of shopping centres is of paramount importance. Unless stores succeed in attracting their own clientele, they rely to a large extent on the impulse behaviour of shoppers. To evaluate alternative locations, models of pedestrian behaviour may be useful. Modern technologies such as GPS and RFID offer new possibilities providing data on routes and stops, which are required as input for such models. An automatic interpretation of GPS tracers with respect to the activities being conducted could enhance the applicability of such technologies to retail management applications. This paper reviews this rapidly growing literature, and shows how automatic data imputation can be established by using Bayesian belief networks and how GPS traces can be fused with land use data of retail location.     

Market Entry Strategies in Emerging Markets: An Institutional Study in the BRIC Countries

This article addresses two of the strategically important questions of market entry strategies in emerging markets: how to enter and when to enter. Furthermore, we investigate the relationship between market entry strategies and market success. On the basis of the institutional theory, we develop hypotheses that are tested against data collected from 564 foreign firms with operations in the BRIC countries (Brazil, Russia, India, and China), using an online survey. Our findings suggest that market entry strategies have a significant effect on market success, showing the greatest market success in India and the lowest in China. We also find that entry mode and length of operation exhibit a significant positive effect on market success. © 2013 Wiley Periodicals, Inc.     

Improvement of Operational Performance of Internationalized Companies through Collaboration in Distribution Networks

Abstract

The purpose of this paper is to provide theoretical insights on the impact of supply chain collaboration on the operational performance of firms and collaborative advantage as an intermediate variable in the context of the supply networks of internationalized firms. The research is based on a case study of a distribution network constituting Russian and international firms. The obtained results indicate that supply chain collaboration improves operational performance of internationalized firms and firms in domestic market. Moreover, the study advocates that collaboration in distribution networks can be considered as driving factor for international firms to enter the emerging markets through supply networks.
