The productivity gains associated with hiring from more productive firms are equivalent to 0.35 percent per year for an average firm. Surviving a variety of statistical controls, these gains increase with education, tenure, and skill level of new hires, persist for several years after the hiring was done, and remain broadly similar for different industries and measures of productivity. Competing explanations for these gains, knowledge spillovers in particular, are discussed. Stoyanov, A. Zubanov, N.V. http://repub.eur.nl/res/pub/14055/ 2008-11-17T00:00:00Z This article analyzes the role of suggested prices in the Dutch retail market for gasoline. Suggested prices are announced by large oil companies with the suggestion that retailers follow them. There are at least two competing rationales for the existence of suggested prices: they may either help retailers translate changes in international gasoline spot market prices into retail prices, or they may coordinate retail prices. We show that there is, next to the international spot market prices, additional information in suggested prices that explains retail prices. Therefore, we conclude that suggested prices help to coordinate retail prices. Faber, R.P. Janssen, M.C.W. http://repub.eur.nl/res/pub/13670/ 2008-05-08T00:00:00Z This study analyses 1400 research projects of the top 20 R&D-spending pharmaceuticals to identify the determinants of successful research projects. We provide clear evidence that externally sourced projects and projects involving biotechnologies perform better than internal projects and chemical projects, respectively. Controlling for these effects, we find that big pharma should either build a critical mass of disease area knowledge or diversify projects over different DA’s in order to obtain higher success probabilities. Projects in which a firm has built a critical mass of disease knowledge (through at least 10 projects per DA) are significantly more likely to reach clinical testing. Moreover, within large disease areas, the success probabilities of internal projects increases when a few (less than 20%) externally sourced projects are involved. We interpret this finding as knowledge spillovers from external to internal projects, as the limited number of external projects enables the same people to be involved in both external and internal research projects and apply externally generated knowledge internally. Phlippen, S.M.W. Vermeersch, A. http://repub.eur.nl/res/pub/12246/ 2008-04-25T00:00:00Z This paper links communications and media usage to social and household economics boundaries. It highlights that in present day society, communications and media are a necessity, but not always affordable, and that they furthermore open up for addictive behaviours which raise additional financial and social risks. A simple and efficient methodology compatible with state-of-the-art social and communications business statistics is developed, which produces the residual communications and media affordability budget and ultimately the value-at-risk in terms of usage and tariffs. Sensitivity analysis provides precious information on communications and media adoption on the basis of affordability. Case data are surveyed from various countries. ICT policy recommendations are made to support widespread and responsible communications access. Pau, L-F. http://repub.eur.nl/res/pub/11762/ 2008-03-19T00:00:00Z China’s mobile communications market presents unique market challenges. With a high subscriber growth rate but polarized and stratified consumer adoption trends, an investigation into the current status of this market will improve our understanding on how adoption of mobile communications is evolving. In this descriptive paper we analyze key issues relating to market characteristics of mobile communications with an objective to better comprehend the dynamics of this largest mobile subscribers market. Using secondary data we identify mobile industry and end-user related trends to infer our conclusions for the industry. Sangwan, S. Chong, G. Pau, L-F. http://repub.eur.nl/res/pub/11141/ 2008-02-07T00:00:00Z Individual services and tariffs existed briefly in the beginning of telecommunications history 150 years ago but faded away over time. Service provisioning evolved into the current supplier-centric situation which has many limitations and disadvantages. This thesis re-embraces the user-centric service provisioning and tariffing philosophy and applies it to current mobile communication services setting, which differs significantly in scale and scope from the historical practices. A design methodology and tool for the determination of individualized mobile services and tariffs is provided, and benefits to both the user and the supplier are evaluated. The design has three aspects. The first involves the construction of a conceptual framework consisting of the behavioral models of the user and the supplier (firm) and a game theoretical negotiation mechanism to determine individual services and tariffs. Second is the operationalization of the conceptual framework in a computational design with methods, computational models, negotiation algorithms, risk metrics and a prototype implementation. Third is the extension of the individual services and tariffs concept to a community setting via a proposed community business model. Two evaluations are performed. First, for the firm-based design, a user survey is conducted and computational cases, that address value-added mobile services and generic mobile service bundles, are developed. The numerical analyses show that the users always achieve gains in utility. The benefits to the supplier include adjustable risk-profit equilibrium points, increased network traffic and reduced churn. Second, two case studies on communities are conducted. The results demonstrate that the proposed business model of community-based individual service provisioning and tariffing can meet the demands of their members precisely and address both affordability and sustainability issues. Last, a specific engineering implementation and integration of the individualized service and tariff design tools into the existing infrastructure of the communication services suppliers is proposed. Further research issues are pointed out. Chen, H. http://repub.eur.nl/res/pub/13562/ 2008-02-01T00:00:00Z Managing through projects has become important for generating new knowledge to cope with technological and market discontinuities. This paper examines how the fit between the creation of technological and market knowledge and important project management characteristics, i.e. project autonomy and completion criteria, influences the success of new business development (NBD) projects. In-depth longitudinal case research on NBD projects commercialised from 1993 to 2003 in the consumer electronics industry highlights that project management characteristics focusing only on the creation of technological knowledge contributed to the failure of those NBD projects that required new market knowledge as well. The findings indicate that senior management support and engaging in an alliance with partners possessing complementary market knowledge can offset this misalignment of the organisation of NBD projects.

Bosch, F.A.J. van den Volberda, H.W. http://repub.eur.nl/res/pub/10718/ 2007-11-04T00:00:00Z Warnings to the broad population in an emergency situation, irrespective of location and condition, is a public policy responsibility. Public wireless networks offer now the opportunity to deliver emergency warnings in this way with explanations, because in many countries the mobile penetration rates are higher than any other access form .The paper summarizes the analysis of the selection process between Short messaging services (SMS) and Cell Broadcast messaging in the context of Denmark based on end user requirements and stakeholder roles. It demonstrates the many technical, cost-benefit and other trade-offs needed in supporting the population now with a dependable and wide-spread technology. Simonsen, P.

Burgers, J.H. Bosch, F.A.J. van den Volberda, H.W. http://repub.eur.nl/res/pub/10503/ 2007-08-28T00:00:00Z This paper introduces a conceptual framework and a computational model for individual tariffs for mobile communication services. The purpose is to provide guidance for implementation by communication service suppliers or user groups alike. The paper first examines the sociological and economic incentives for personalized services and individual tariffs. Then it introduces a framework for individual tariffs which is centered on user and supplier behaviours. The user, instead of being fully rational, has "bounded rationality" and his behaviours are subject to economic constraints and influenced by social needs. The supplier can belong to different types of entities such as firms and communities; each has his own goals which lead to different behaviors. Individual tariffs are decided through interactions between the user and the supplier and can be analyzed in a structured way using game theory. A numerical case in mobile music training is developed to illustrate the concepts. Chen, H. Pau, L-F. http://repub.eur.nl/res/pub/10515/ 2007-08-28T00:00:00Z This paper presents results on mass customization of wireless communications services and tariffs. It advocates for a user-centric view of wireless service configuration and pricing as opposed to present-day service catalog options. The focus is on design methodology and tools for such individual services and tariffs, using altogether information compression, negotiation algorithms, and risk portfolio analysis. We first analyze the user and supplier needs and aspirations. We then introduce the systematic design-oriented approach which can be applied. The implications of this approach for users and suppliers are discussed based on an end-user survey and on model-based calculations. It is shown that users can achieve desired service bundle cost reduction, while suppliers can improve significantly their risk-profit equilibrium points, reduce churn and simplify provisioning. Chen, H. Pau, L-F. http://repub.eur.nl/res/pub/10518/ 2007-08-28T00:00:00Z A design approach is offered for individual tariffs for mass customized mobile service products, whereby operators can determine their contract acceptance rules to guarantee with a set probability their minimum profit and risk levels. It uses realistic improvements to earlier reported negotiation algorithms [1], and a full operator operational model including infrastructure and content acquisition. Value at risk and profit are analyzed when a random user has consistent characteristics to a survey group, so that risk and profits are pooled. This analysis is necessary to give the supplier business guarantees to enter individual tariff agreements. A full numerical case is given for a class of mobile service. Chen, H. Pau, L-F. http://repub.eur.nl/res/pub/10519/ 2007-08-28T00:00:00Z This paper introduces individual tariffs at service and content bundle level in mobile communications. It gives a theoretical framework (economic, sociological) as well as a computational game solution method. The user can be an individual or a community. Individual tariffs are decided through interactions between the user and the supplier. A numerical example from mobile music illustrates the concepts. Chen, H. Pau, L-F. http://repub.eur.nl/res/pub/10455/ 2007-07-03T00:00:00Z Steel structures such as bridges, tanks and pylons are exposed to outdoor weathering conditions. In order to prevent them from corrosion they are protected by an organic coating system. Unfortunately, the coating system itself is also subject to deterioration. Imperfect maintenance actions such as spot repair and repainting can be done to extend the lifetime of the coating. In this paper we consider the problem of finding the set of actions that minimizes the expected maintenance costs over a bounded horizon. To this end we model the size of the area affected by corrosion by a non-stationary gamma process. An imperfect maintenance action is to be done as soon as a fixed threshold is exceeded. The direct effect of such an action on the condition of the coating is assumed to be random. On the other hand, maintenance may also change the parameters of the gamma deterioration process. It is shown that the optimal maintenance decisions related to this problem are a solution of a continuous-time renewal-type dynamic programming equation. To solve this equation time is discretized and it is verified theoretically that this discretization induces only a small error. Finally, the model is illustrated with a numerical example. Nicolai, R.P. Frenk, J.B.G. Dekker, R. http://repub.eur.nl/res/pub/10183/ 2007-06-01T00:00:00Z Erik P. van Leeuwen (Gouda, Netherlands, January 5, 1974) began his study Mechanical Engineering at the Polytechnics Department of the HTS Dordrecht and specialised in Energy Management. After receiving his Bachelor degree in 1997, he wanted to enlarge his management knowledge by taking a MSc in Business Administration at the RSM Erasmus University with a major in Strategic Management. The topic of his Master thesis was: Knowledge Absorption in Strategic Alliances. For this purpose he investigated the Joint Venture between ENECO and Shell Energy from a learning perspective. He received his Master’s degree in 2000 and started a Management Traineeship at Kappa Packaging, (Smurfit Kappa nowadays) one of Europe’s leading producers of Paper & Board Packaging. In 2003, after his traineeship, Erik van Leeuwen accepted a job as Recovered Paper Researcher at Kappa Paper Recycling, department of Market Intelligence, and simultaneously started his PhD research at the Department of Strategic Management and Business Environment of the RSM Erasmus University. At present he is associated with the department and involved in supervising Master theses. Since February 2007, Erik van Leeuwen works as a Senior Business Analyst at ENECO Energy, department ENECO Milieu. Leeuwen, E. van http://repub.eur.nl/res/pub/9043/ 2007-02-17T00:00:00Z Wireless penetration and the Indian economy have grown significantly over the past few years, but how robust and sustainable is the adoption of wireless services and products? Several papers have discussed India as a wireless service and product market, and sometimes tried to assess quantitative attributes thereof. The present paper aims instead at looking, from a management point of view, at the unique underlying evolution processes, bottlenecks and risks. On specific facets, a comparison is given to adoption indicators in other key markets such as China. For example, just to illustrate highlights of these unique attributes , it is indeed surprising that such a major economy with its very large population has not yet achieved the wireless service usage and mobile terminal penetration ratios of neither an early European adopter ,nor of a recent large scale adopter like China or Russia . India has also been characterised by a surprising regulatory development process quite different from many other contexts, both in terms of its both centralised and regional structure, of very low tariffs providing almost no ROI to investors in a stable situation, and of absence of neutrality across communications technologies. At the same time, a very large fraction of the population has not , for affordability and regional coverage reasons, been able to get the access opportunities of more developed regions , leading to a distribution unbalance which is also a significant opportunity .Also , the wireless service and product adoption pattern in India , specific to communicating services , has so far been in rather sharp contrast with the widely known software and outsourcing services industry evolutions in that country . Therefore it is important to compare the most relevant known wireless service and product adoption theories, to establish from facts whether they apply in the Indian context, and, if not, suggest new or mixed theories able to explain all such facts and cast some light into its likely future structural evolution. It is of high relevance in management to validate if indeed established models apply or not in a significant case like India, just as it is also of high relevance for the main stakeholders to identify methodology able to support their analyses. The paper first provides background information on wireless, fixed, and other operators, on wireless penetration, on telecommunications infrastructure and investments, and on Indian human capital. Thereafter is analyzed in detail the relevance, or not, of five traditional technology adoption models across the Indian user base: the absorption business model, the perceived benefits business model, consumer attitudes, the globalisation business model, and finally the brand management business model. These first analyses are followed by the identification and detailed analysis of five other business models or structural processes, some rather unique to India: the two-tier migration model, large scale imported adoption without a telecommunications infrastructure & terminals industry, unstable adoption with lack of consistent public policies, knowledge sharing and productivity enhancement adoption model, and finally late foreign capital investments into a large emerging market. From the comparison of facts and background data , with these ten wireless service and product adoption models , the paper establishes which are not relevant, and which are too some degree . Furthermore the relevant business models are shown to share, further attributes of sustainability (or not) and dynamic behaviour. This allows concluding that India has had an overall quite fragile adoption and deployment path with growing tensions such as coverage, quality of service and affordability disparities. The model comparison also allows to diagnose the key three structural measures needed to reach a sustainable equilibrium from the business, economic and social points of view. Pau, L-F. Motiwalla, J. http://repub.eur.nl/res/pub/8110/ 2006-11-16T00:00:00Z Recognizing the importance of privacy management as a business process and a business support process, this paper proposes the use of service level agreements (SLA’s) around privacy features, including qualitative and quantitative ones. Privacy metrics are defined by both parties with boundary values on each qualitative or qualitative feature. Their distribution is relying on stress distributions used in this field. The use of service level agreements also casts privacy management into a business perspective with benefits and costs to either party in a process. This approach is especially relevant for communications operators as brokers between content owners (individuals, businesses) and enterprise applications; in this context, the privacy SLA management would be carried out by the operator, while the terms and conditions of the SLA negotiation reside with the two external parties. This work was carried out as part of the large EU project PRIME www.prime.project.eu.org. on privacy enhancing technologies. Pau, L-F. http://repub.eur.nl/res/pub/7593/ 2006-03-17T00:00:00Z Het doel van dit onderzoek is het analyseren van de marktgrootte van mobiel betalen en de bijbehorende omzetbasis, alsmede de invoering van knelpunten, om inzicht te verkrijgen in de introductie en ontwikkeling van mobiele bankservices in Nederland. Het onderzoek beschrijft verscheidene aspecten van mobiel betalen/mobiel bankieren in Nederland. Onderwerpen als implementatie, wetgeving, geschatte businesscase, aanbevolen businessmodel, ontwikkelingsscenario’s, een SWOT - analyse van technische oplossingen, organisatorische knelpunten, een analyse van de redenen van succes en falen en openstaande problemen en uitdagingen komen aan de orde. Het voornaamste doel van het onderzoek is het trachten te beantwoorden van de vraag of er een markt voor mobiel betalen is in Nederland en een analyse geven van waarom mobiele bankservices niet succesvol zijn geweest in Nederland. Bovendien dient gemeld te worden dat de focus van dit verslag lag op microbetalingen, waar over het algemeen betalingen tot €10 onder verstaan worden. Waris, F.S. Mubarik, F.M. Pau, L-F. http://repub.eur.nl/res/pub/7319/ 2006-02-01T00:00:00Z With the emergence of smart business networks, agile networks, etc. as important research areas in management, for all the attractiveness of these concepts, a major issue remains around their design and the selection rules. While smart business networks should provide advantages due to the quick connect of business partners for selected functions in a process common to several parties, literature does not provide constructive methods whereby the selection of temporary partners and functions can be done. Most discussions only rely solely on human judgment. This paper introduces both computational geometry, and genetic programming, as systematic methods whereby to display possible partnerships, and also whereby to plan for their effect on the organizations or functions of those involved. The two techniques are also been put in the context of emergence theory. Business maps address the first challenge with the use of Voronoï diagrams. Cellular automata, with genetic algorithms mimicking living bodies, address the second challenge. This paper does not include experimental results, which have been derived in the high tech area to determine especially the adequateness of systems integrators to set up joint ventures with smaller technology suppliers. Pau, L-F. http://repub.eur.nl/res/pub/6989/ 2005-10-14T00:00:00Z Diffusion of mobile communication has induced great societal changes in China. Factors at global market, communications industry and end-user market levels are driving the adoption at a high rate. Firstly, China’s economic emergence together with e.g. accession to WTO has led to foreign investment increase in telecom and communications industry. Secondly, a parallel deregulation and reengineering of the telecom industry ensured an introduction of competition in the domestic terminals market and facilitated manufacturing in China. Finally, overall growth in China has increased purchasing power enabling consumers to adopt new technologies. At the market level, challenges and future growth depends on a favorable business environment both for local and multinationals organizations, operators and service providers, and most importantly to the distribution channels (retailers and resellers). Market mechanisms such as improvement in payment methods, regulations for content providers, branded and low-end mobile phones marketing, applications and support in Chinese language are required for a systematic and not just sporadic adoption of mobile devices. Product development and innovation, improvement in distribution infrastructure, mobile services operators skill enhancement are some measures that can growth of mobile communication and increase in average consumer spending.
