Under realistic assumptions, we find that all agents can benefit from the technology change, provided that the observed rise in redistributive transfers over this period is taken into account. We show that the increase in capital’s share of total income and the presence of capital-entrepreneurial skill complementarity are two key features that help support the wages of ordinary workers as the new technology diffuses Lansing, K.J. Markiewicz, A. http://repub.eur.nl/res/pub/37701/ 2012-04-01T00:00:00Z Using matched firm-worker data from Danish manufacturing, we observe firm-to-firm worker movements and find that firms that hired workers from more productive firms experience productivity gains one year after the hiring. 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/18463/ 2010-03-02T00:00:00Z This paper studies the adoption times of various e-business technologies in a large sample of firms from 10 different industry sectors and 25 European countries between 1994 and 2002. The results show that the probability of adoption increases with the number of previously adopted e-business technologies. Hence, the more advanced a firm is in using e-business technologies, the more likely it is to adopt additional e-business technologies, provided technologies do not substitute each other in their functionalities. This result is relevant for the marketing of new technologies, strategic planning and, from an economic perspective, for the convergence of growth across regions. Koellinger, Ph.D. Schade, C. http://repub.eur.nl/res/pub/21867/ 2010-01-01T00:00:00Z Applying quantile regression to 760 Finnish firms, we show that the relationship between R&D and firm performance is less straight forward than so far assumed. OLS regression analysis fails to capture the effect of R&D expenditure at different locations on the performance distribution. We reveal that R&D matters, especially on the medium quantiles, while regressing against the upper quantiles of the economic gains from innovation distribution exhibit decreasing returns scale in R&D. Our results confirm that Gaussian statistics fail to capture the most interesting part of the distribution - namely the extreme observations located in the tails. Ebersberger, B. Marsili, O. Reichstein, T. Salter, A. http://repub.eur.nl/res/pub/11809/ 2009-02-03T00:00:00Z This paper studies the diffusion of multiple related technologies among firms. The results suggest an endogenous acceleration mechanism for technology adoption: The more advanced a firm is in using a particular set of technologies, the more likely it is to adopt additional related technologies. We show that such a mechanism can occur under fairly general circumstances. If firms are not ex ante identical, the endogenous acceleration mechanism suggests a growing divergence in the technological endowment of firms in the early phases after the emergence of a new technological paradigm. The theoretical predictions are tested with a dataset that records the adoption times of various e- business technologies in a large sample of firms from 10 different industry sectors and 25 European countries. The results show that the probability of adoption increases with the number of previously adopted e-business technologies. Evidence for a growing digital divide among the companies in the sample is demonstrated for the period from 1994-2002. Koellinger, Ph.D. Schade, C. http://repub.eur.nl/res/pub/14042/ 2008-09-03T00:00:00Z This paper studies the diffusion of multiple, related technologies among firms. The results suggest an endogenous acceleration mechanism of technology adoption: The more advanced a firm is in using a particular set of technologies, the more likely it is to adopt additional, related technologies. We show that such a mechanism can occur under fairly general circumstances. If firms are not ex ante identical, the endogenous acceleration mechanism suggests a growing divergence in technological endowment of firms in the early phases after the emergence of a new technological paradigm. The theoretical predictions are tested with a dataset that records the adoption times of various e-business technologies in a large sample of firms from 10 different industry sectors and 25 European countries. The results show that the probability to adopt strictly increases with the number of previously adopted e-business technologies. Evidence for a growing digital divide among the companies in the sample is demonstrated for the period from 1994-2002. Koellinger, Ph.D. Schade, C. http://repub.eur.nl/res/pub/13576/ 2008-01-31T00:00:00Z Existing studies of supplier involvement in new product development have mainly focused on project-related short-term processes and success factors. This study validates and extends an existing exploratory framework, which comprises both long-term strategic processes and short-term operational processes that are related to supplier involvement. The empirical validation is based on a multiple-case study of supplier collaborations at a manufacturer in the copier and printer industry. The analysis of eight cases of supplier involvement reveals that the results of supplier–manufacturer collaborations and the associated issues and problems can best be explained by the patterns in the extent to which the manufacturer manages supplier involvement in the short term and the long term. The results of this study reveal that the initial framework is helpful in understanding why certain collaborations are not effectively managed yet conclude that the existing analytical distinction among four different management areas does not sufficiently reflect empirical reality. This leads to the reconceptualization and further detailing of the framework. Instead of four managerial areas, this study proposes to distinguish between the strategic management arena and the operational management arena. The strategic management arena contains processes that together provide long-term, strategic direction and operational support for project teams adopting supplier involvement. These processes also contribute to building up a supplier base that can meet current and future technology and capability needs. The operational management arena contains processes that are aimed at planning, managing, and evaluating the actual collaborations in a specific development project. The results of this study suggest that success of involving suppliers in product development is reflected by the firm's ability to capture both short- and long-term benefits. If companies spend most of their time on operational management in development projects, they will fail to use the leverage effect of planning and preparing such involvement through strategic management activities. Also, they will not be sufficiently able to capture possible long-term technology and learning benefits that may spin off from individual projects. Long-term collaboration benefits can only be captured if a company can build long-term relationships with key suppliers, with which it builds learning routines and ensures that the capability sets of both parties are aligned and remain useful for future joint projects.

Weele, A.J. van Duysters, G.M. http://repub.eur.nl/res/pub/14765/ 2008-01-01T00:00:00Z In this conceptual paper we investigate how corporate venturing influences an organization’s competences. The impact of various types of corporate ventures on the portfolio of strategic options of a firm’s competence modes (Sanchez, 2004a; Sanchez and Heene, 2002) will be assessed by distinguishing two fundamentally different dimensions of corporate venturing, technology and product (Block & MacMillan, 1993). We argue that the level of product and factor market dynamism mediates the effect of corporate venturing on a firm’s competence modes. Corporate ventures that significantly increase the level of product or factor market dynamics will lead to an increased flexibility in all five competence modes. These ventures will have a direct effect on the lower-order competence modes and an indirect, lagged effect on higher-order competence modes through feedback loops. The developed framework and the propositions contribute to managing the ability of a firm to change its coordination-, resource and operating flexibility in order to sustain value creation.

Bosch, F.A.J. van den Volberda, H.W. 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/10456/ 2007-06-25T00:00:00Z This paper examines how firms succeed to leverage supplier involvement in product development. The paper extends earlier work on managing supplier involvement by providing an integrated analysis of results, processes and conditions both at the level of individual development projects and the overall firm. Following a multiple-case study approach with theoretical sampling, the study is carried out by examining eight projects in which four manufacturers from different industries involve multiple suppliers. The findings suggest that successful supplier involvement is dependent on the coordinated design, execution and evaluation of strategic, long-term processes and operational, short-term management processes and the presence of enabling factors such as a cross-functional oriented organization. The required intensity of these processes and enablers depends on contingencies such as firm size and environmental uncertainty. In contrast with previous research, we find no indications that managing supplier involvement requires a different approach in highly innovative projects compared to less innovative projects. Echtelt, F.E.A. van Wynstra, J.Y.F. Weele, A.J. van http://repub.eur.nl/res/pub/10149/ 2007-05-24T00:00:00Z The non-stationary gamma process is a non-decreasing stochastic process with independent increments. By this monotonic behavior this stochastic process serves as a natural candidate for modelling time-dependent phenomena such as degradation. In condition-based maintenance the first time such a process exceeds a random threshold is used as a model for the lifetime of a device or for the random time between two successive imperfect maintenance actions. Therefore there is a need to investigate in detail the cumulative distribution function (cdf) of this so-called randomized hitting time. We first relate the cdf of the (randomized) hitting time of a non-stationary gamma process to the cdf of a related hitting time of a stationary gamma process. Even for a stationary gamma process this cdf has in general no elementary formula and its evaluation is time-consuming. Hence two approximations are proposed in this paper and both have a clear probabilistic interpretation. Numerical experiments show that these approximations are easy to evaluate and their accuracy depends on the scale parameter of the non-stationary gamma process. Finally, we also consider some special cases of randomized hitting times for which it is possible to give an elementary formula for its cdf. Frenk, J.B.G. Nicolai, R.P. http://repub.eur.nl/res/pub/8020/ 2006-10-09T00:00:00Z Local authorities increasingly use time-access regulations to improve social sustainability issues, such as the attractiveness of a city centre, the shopping climate, or to reduce the nuisance caused by urban freight transport. However, these time-windows increase delivery costs and the environmental burden. This paper evaluates five different time-window schemes on their social, environmental, and economic impacts. The first scheme examines the current time-window policy scheme. In the second scheme time-windows are harmonized between different cities. The third scheme moves all deliveries to the night. The fourth and fifth schemes evaluate the consequences of the proposal by the Dutch committee for urban distribution (committee Sakkers). The fourth scheme includes noise-legislation for delivering during the night, the fifth does not. This research includes interviews with several Dutch policy-making officials and is further based on a multiple-case study of fourteen large retail chains in different sectors and with different formulas. The results show that the current time-window scheme performs worst. The best time-window scheme would be a combination of the proposal of the committee Sakkers and the harmonization scenario.

It involves, amongst others, the embedding of business logic specific to a network of business partners, inside the communications control networks .It also involves the definition of business protocols between these partners and the joint management of some common functions relying on open networking standards. This implies some key paradigm changes, both of a technical and of a business nature, which are offered here for discussion via a set of propositions. Pau, L-F. http://repub.eur.nl/res/pub/6613/ 2004-10-15T00:00:00Z Which signals are important in gaining attention in science? For a group of 1,371 scientific articles published in 17 demography journals in the years 1990-1992 we track their influence and discern which signals are important in receiving citations. Three types of signals are examined: the author’s reputation (as producer of the idea), the journal (as the broker of the idea), and the state of uncitedness (as an indication of the assessment by the scientific community of an idea). The empirical analysis points out that, first, the reputation of journals plays an overriding role in gaining attention in science. Second, in contrast to common wisdom, the state of uncitedness does not affect the future probability of being cited. And third, the reputation of a journal may help to get late recognition (so-called ‘sleeping beauties’) as well as generate so-called ‘flash-in-the-pans’: immediately noted articles but apparently not very influential in the long run. Dalen, H.P. van Henkens, K. http://repub.eur.nl/res/pub/820/ 2003-09-04T00:00:00Z This paper studies the adoption and diffusion of energy-saving technologies in a vintage model. An important characteristic of the model is that vintages are modeled as being complementary: there are returns to diversity of using different vintages. We analyse how diffusion patterns and adoption behaviour are affected by complementarity and learning-by-using. It is shown that the stronger the complementarity between different vintages and the stronger the learning-by-using, the longer it takes before firms scrap (seemingly) inferior technologies. We argue that this is a potentially relevant part of the explanation of the energy-efficiency paradox. Furthermore we explore the effects of energy tax policies. Groot, H.L.F. de Hofkes, M.W. Mulder, P. http://repub.eur.nl/res/pub/827/ 2003-09-04T00:00:00Z The diffusion of new technologies is a lengthy process and many firms continue to invest in relatively old technologies. This paper develops a vintage model of technology adoption and diffusion that aims at explaining these two phenomena. Our explanation for these phenomena emphasises the relevance of complementarity between different vintages (or, alternatively, returns to diversity) and learning-by- using. The model is characterised by simultaneous investments in vintages of different quality and endogenously determined scrapping of old technologies. We show that the stronger the complementarity between different vintages and the stronger the learning-by-using, the longer it takes before firms scrap (seemingly) inferior technologies. Groot, H.L.F. de Hofkes, M.W. Mulder, P. http://repub.eur.nl/res/pub/239/ 2002-10-22T00:00:00Z An assumption generally subscribed in evolutionary economics is that new technological paradigms arise from advances is science and developments in technological knowledge. Demand only influences the selection among competing paradigms, and the course the paradigm after its inception. In this paper we argue that this view needs to be adapted. We demonstrate that in the history of computing technology in the 20th century a distinction can be made between periods in which either demand or knowledge development was the dominant enabler of innovation. In the demand enabled periods new technological (sub-) paradigms in computing technology have emerged as well. Ende, J.C.M. van den Dolfsma, W.A.
