银行业改革、赶超与开放——基于Malmquist TFP指数的实证分析

为评估近年来中国国有银行改革、城市商业银行赶超与银行业对外全面开放5年来外资银行效率的变化,主要采取"中介法",利用2005～2010年数据对中国本土和外资银行Malmquist TFP指数及其组成部分进行了测算分解和实证分析。研究表明:改革促进了中国银行业效率的提高;城市商业银行的"赶超"战略显著提升了效率;中国本土银行的纯技术效率亟待改善;中国银行业对外全面开放后,外资银行的全要素生产率有所提高,但规模效率和技术进步有待改进;股权/资产比率等因素降低了银行效率。     

The Impact of the EU–US Open Skies Agreement and the Resulting British Airway's Open Skies Initiative: Passenger Numbers in London,Amsterdam and Paris

Abstract

The advent of the EU–US Open Skies Agreement has been widely anticipated. A number of consequences have been predicted, for example, impacts on fares, passenger volumes, choice and consumer welfare. Airline costs are also predicted to fall as a result of increased competitiveness and increased cooperation among airlines. For the short period since the implementation of the Agreement, it is relatively easy to assess the supply-side changes that have been made, but more difficult to make wider judgements. This paper indicates the data that will be required to make these judgements and notes some methodological difficulties. Early estimates of the impact on passenger numbers are given using time series analysis focusing on London airports, in particular London Heathrow and airports served by British Airway's Open Skies Airline from Paris Orly and Amsterdam Schipol.

Impact de l'accord Ciel Ouvert entre l'UE et les États-Unis et de l'initiative Open Skies résultante de British Airways: nombre de passagers à Londres, Amsterdam et Paris

Résumé L'avènement de l'accord Ciel ouvert entre l'UE et les États-Unis avait été très largement prévu, et on a prédit un certain nombre de conséquences, notamment l'impact sur le prix des billets, sur les volumes de passagers, sur le choix pour les consommateurs et sur leur bien-être, entre autres. On prévoit également que les coûts des compagnies d'aviation devraient baisser, en conséquence de l'augmentation non seulement de la compétitivité, mais aussi de la concurrence entre les compagnies. A l'issue de la courte période qui s'est écoulée depuis l'implémentation de l'Accord, il est relativement aisé d’évaluer les variations qui se sont produites du côté de l'offre, mais beaucoup plus difficile de formuler des opinions plus générales. La présente communication indique les données qui seront requises pour formuler ces jugements, et souligne certaines difficultés sur le plan de la méthodologie. Des premières évaluations de l'impact sur le nombre de voyageurs ont été avancées, sur la base d'analyses à série temporelle concentrées sur les aéroports de Londres, notamment l'aéroport Heathrow de Londres et les aéroports desservis par la compagnie Open Skies de British Airway entre Paris Orly et l'aéroport Schipol d'Amsterdam.

El efecto del Acuerdo de Cielos abiertos entre la UE y EE.UU. y el resultado de la Iniciativa de Cielos abiertos de British Airways: número de pasajeros en Londres, Ámsterdam y París

Resumen El advenimiento del Acuerdo de Cielos abiertos entre la EU y EE.UU. era algo ampliamente esperado. Se han pronosticado muchas consecuencias, por ejemplo, los efectos sobre las tarifas, los volúmenes de pasajeros, las opciones y el bienestar de los consumidores. También se ha pronosticado la caída de los costes de las aerolíneas debido a una mayor competitividad y el incremento de la cooperación entre las aerolíneas. En el corto periodo de implantación del Acuerdo, es relativamente fácil evaluar los cambios que se han dado en el lado de la oferta, sin embargo, es más difícil realizar estimaciones mayores. Este trabajo indica que se necesitan datos para realizar estas estimaciones y hace referencia a algunas dificultades metodológicas. Los primeros estimativos del efecto sobre los números de pasajeros se han obtenido mediante análisis de series de tiempo centrados en los aeropuertos de Londres, en particular, el de Heathrow, y en los aeropuertos atendidos por la Aerolínea de Cielos abiertos de British Airways de Orly, en París, y Schipol, en Ámsterdam.

     

Was the Internet the Only Option? Which Way Should Business and Information Systems Engineering Go?

In global competition, the Internet turned out to be the single and hegemonial infrastructure for communication. It has become the “nervous system” of today’s networked economy. While the first phase provided communication services, like e-mail, the WWW has established an interactive platform to allow easy access to advanced services. Now, in its “third” or cooperative phase, the Internet will finally lead to a ubiquitous informatization where business processes and applications become interleaved beyond the boundaries of enterprises. For this phase, many analogies to the emergence of the Internet can be observed.     

Technology commercialization intelligence: Organizational antecedents and performance consequences

External technology commercialization, e.g., by means of technology licensing, has recently gained in importance. Despite imperfections in technology markets, out-licensing constitutes a major technology commercialization channel. Although the identification of licensing opportunities represents a significant managerial challenge, prior research has relatively neglected these activities. Therefore, we develop the concept of ‘technology commercialization intelligence’ (TCI), which refers to the observation of a firm's environment with particular focus on identifying technology licensing opportunities. Grounded in a dynamic capabilities perspective, we test five hypotheses regarding organizational antecedents and performance consequences of TCI, drawing on data from a survey of 152 companies. The empirical findings provide strong support for the importance of the TCI concept. The findings deepen our understanding of the discrepancies between successful pioneering firms active in technology licensing and many others being less successful. The results have major implications for technology exploitation in open innovation processes.     

Pragmatism, not ideology: Historical perspectives on IBM’s adoption of open-source software

We track IBM’s approach to software production and commercialization between 1950 and the present. We find that in the 1950s IBM followed what today would be called an open-source model – its software source code was open, free of charge, and written collaboratively with its users. By the mid 1980s, all of these attributes had been reversed – IBM’s software was closed source, sold or leased independently of hardware sales, and written without the collaboration of its users. More recently, the company has been in a state of transition, achieving a balance between free, open-source software and proprietary software that still generates 20% of its revenues. We interpret these radical swings in light of the substantial changes that have taken place since the 1950s in the costs and benefits of open source, bundled, and collaborative software vis-à-vis the alternatives.     

Competition and open source with perfect software compatibility

In this paper we study duopolistic competition between closed and open source software. Inspired by recent contributions on open source, we propose a two-stage game with perfect information and product differentiation, in which producers first set software quality and then determine prices (the price is zero for open source programs). We assume perfect software compatibility and model lock-in effects, a network externality component of software quality, and accumulation of experience in software use and implementation. In comparison to the monopolistic benchmark case, we argue that, in a duopoly created by the emergence of an open source program, the proprietary software producer will reduce its selling price if: (i) its network of users is larger than the open source network and its consumers are largely familiar with its program, (ii) it has a small network of unskilled consumers. On the other hand, the price of proprietary software will increase if its users form a large, but poorly-skilled network. Furthermore, we show that, in all of the above cases, the hedonic quality of proprietary software increases. Finally, by modeling experience accumulation processes through difference equations, we show that the ratio between the closed and open source programs’ opportunity costs for software learning and deployment plays a crucial role in shaping market outcomes. If open source software remains too complex and technical for unskilled or time-pressed users, a shared market solution, in which both programs are adopted, is likely to emerge. However, if opportunity costs in learning and understanding open source programs are particularly low, or at least equal to the opportunity costs of a closed-source program, then open source dominance emerges (i.e. markets tip to open source).
