The analysis is based on two conditional multivariate models, BEKK-AGARCH and VARMA-AGARCH, in the volatility specification. Daily data from 1 July 2008 to 29 June 2012 for 999 firms are used, which covers the Global Financial Crisis. The empirical findings indicate that there are size effects on volatility spillovers from the exchange rate to firm performance. Specifically, the risk for firm size has different effects from the three leading tourism sources to Taiwan, namely USA, Japan, and China. Furthermore, all the return series reveal quite high volatility spillovers (at over sixty percent) with a one-period lag. The empirical results show a negative correlation between exchange rate returns and stock returns. However, the asymmetric effect of the shock is ambiguous, owing to conflicts in the significance and signs of the asymmetry effect in the two estimated multivariate GARCH models. The empirical findings provide financial managers with a better understanding of how firm size is related to financial performance, risk and portfolio management strategies that can be used in practice.

We explicitly model cooperative (dual distribution) franchising as an organizational form, next to wholly-owned, wholly-franchised, and dual distribution franchise systems. Key conclusions of the model are: (1) dual distribution as an efficient governance mechanism does not depend on heterogeneous downstream outlets, and (2) whether dual distribution or some other organizational form is efficient depends on the size of the benefits to dual distribution relative to the parties' costs of investing. Hendrikse, G.W.J. Jiang, T. http://repub.eur.nl/res/pub/25607/ 2011-07-01T00:00:00Z The paper analyses the leading international journals in Tourism and Hospitality Research using quantifiable Research Assessment Measures (RAMs), highlights the similarities and differences in alternative RAMs, shows that several RAMs capture similar performance characteristics of highly cited journals, and shows that some other RAMs have low correlations with each other, and hence add significant informational value. Several RAMs are discussed for the Thomson Reuters ISI Web of Science database (hereafter ISI). Alternative RAMs may be calculated annually or updated daily to answer the questions as to When, Where and How (frequently) published papers are cited. The RAMs include the most widely used RAM, namely the classic 2-year impact factor including journal self citations (2YIF), 2-year impact factor excluding journal self citations (2YIF*), 5-year impact factor including journal self citations (5YIF), Immediacy (or zero-year impact factor (0YIF)), Eigenfactor, Article Influence, C3PO (Citation Performance Per Paper Online), h-index, PI-BETA (Papers Ignored - By Even The Authors), 2-year Self-citation Threshold Approval Ratings (2Y-STAR), Historical Self-citation Threshold Approval Ratings (H-STAR), Impact Factor Inflation (IFI), and Cited Article Influence (CAI). As data are not available for 5YIF, Article Influence and CAI for 11 of the 14 journals considered, 10 RAMs are analysed for 14 highly-cited journals in Tourism and Hospitality in the ISI category of Hospitality, Leisure, Sports & Tourism. Harmonic mean rankings of the 10 RAMs for the 14 highly-cited journals are also presented. It is shown that emphasizing the 2-year impact factor of a journal, which partly answers the question as to When published papers are cited, to the exclusion of other informative RAMs, which answer Where and How (frequently) published papers are cited, can lead to a distorted evaluation of journal impact. Chang, C.L. McAleer, M.J. http://repub.eur.nl/res/pub/25611/ 2011-07-01T00:00:00Z This paper estimates the effects of short and long haul volatility (or risk) in monthly Japanese tourist arrivals to Taiwan and New Zealand, respectively. In order to model appropriately the volatilities of international tourist arrivals, we use symmetric and asymmetric conditional volatility models that are commonly used in financial econometrics, namely the GARCH (1,1), GJR (1,1) and EGARCH (1,1) models. The data series are for the period January 1997 to December 2007. The volatility estimates for the monthly growth in Japanese tourists to New Zealand and Taiwan are different, and indicate that the former has an asymmetric effect on risk from positive and negative shocks of equal magnitude, while the latter has no asymmetric effect. Moreover, there is a leverage effect in the monthly growth rate of Japanese tourists to New Zealand, whereby negative shocks increase volatility but positive shocks of similar magnitude decrease volatility. These empirical results seem to be similar to a wide range of financial stock market prices, so that the models used in financial economics, and hence the issues related to risk and leverage effects, are also applicable to international tourism flows.

Chang, C.L. McAleer, M.J. Lim, C. http://repub.eur.nl/res/pub/19532/ 2010-05-19T00:00:00Z Over the past two decades the internet has rapidly become an important medium to retrieve information, maintain social contacts, and to do online shopping. The latter has some important advantages over traditional shopping. Products are often cheaper on the internet, internet companies sell a wider collection of products and consumers can buy items whenever they like without leaving their homes. On the other hand, the current state of online shops still has two major disadvantages over `real' shops: Products are often much harder to find than in traditional shops and there are no salesmen to advise the customers. In this thesis, we address both these disadvantages. We introduce and evaluate several new user interfaces for online shops that are based on representing products in maps instead of lists to user, such that products are easier to find. In these maps similar products are located close to each other. To create these maps, statistical techniques such as multidimensional scaling are used. Furthermore, we combine these maps with recommender systems to address the second disadvantage and to help the user in finding the product best suiting her needs. Also, we introduce a recommender system that is able to explain the recommendations it gives to users. We think that the methods discussed in this thesis can form a basis for new promising online shopping interfaces both in research as in practice. Kagie, M. http://repub.eur.nl/res/pub/19362/ 2010-04-29T00:00:00Z This paper analyzes the responsiveness of Thai outbound tourism to East Asian destinations, namely China, Hong Kong, Japan, Taiwan and Korea, to changes in effective relative price of tourism, total real total tourism expenditure, and one-off events. The nonlinear and linear Almost Ideal Demand (AID) models are estimated with monthly data to identify the price competitiveness and interdependencies of tourism demand for competing destinations in both long run (static) and short run error correction (dynamic) specifications. The homogeneity and symmetry restricted long run and short run AID models are estimated to calculate elasticities. The income elasticities, and the compensated and uncompensated own-price and cross-price elasticities, provide useful information for public and private tourism agents at the various destinations to maintain and improve price competitiveness. The empirical results show that price competitiveness is important for tourism demand for Japan, Korea and Hong Kong in the long run, and for Hong Kong and Taiwan in the short run. With regard to long run cross-price elasticities, the substitution effect can be found in the following pairs of destinations: China-Korea, Japan-Hong Kong, Taiwan-Hong Kong, Japan-Korea, and Taiwan-Korea. In addition to the substitution effect, the complementary effect can be found in the following pairs of destinations: China-Hong Kong, China-Japan, China-Taiwan, Japan-Taiwan, and Korea-Hong Kong. Contrary to the findings obtained from the long run AID specification, Japan-Korea and Taiwan-Korea are complements in the short run. Furthermore, the real total tourism expenditure elasticities indicate that China’s share of real total tourism expenditure is inelastic in response to a change in real total tourism expenditure, while Korea’s share of real total tourism expenditure is most sensitive to changes in expenditure in the long run. The greatest impact on the share of real total tourism expenditure in the short run is tourism demand for Taiwan. Chang, C.L. Khamkaew, T. McAleer, M.J. http://repub.eur.nl/res/pub/19363/ 2010-04-29T00:00:00Z The significant impact of international tourism in stimulating economic growth is especially important from a policy perspective. For this reason, the relationship between international tourism and economic growth would seem to be an interesting and topical empirical issue. The purpose of this paper is to investigate whether tourism specialization is important for economic development in 159 countries over the period 1989-2008. The results from panel threshold regressions show a positive relationship between economic growth and tourism. Instrumental variable estimation of a threshold regression is used to quantify the contributions of tourism specialization to economic growth, while correcting for endogeneity between the regressors and error term. The significant impact of tourism specialization on economic growth in most regressions is robust to different specifications of tourism specialization, as well as to differences in real GDP measurement. However, the coefficients of the tourism specialization variables in the two regimes are significantly different, with a higher impact of tourism on economic growth found in the low regime. These findings do not change with changes in the threshold variables. The empirical results suggest that tourism growth does not always lead to substantial economic growth. Chang, C.L. Khamkaew, T. McAleer, M.J. 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/17337/ 2009-11-25T00:00:00Z The energy sector will undergo fundamental changes over the next ten years. Prices for fossil energy resources are continuously increasing, there is an urgent need to reduce CO2 emissions, and the United States and European Union are strongly motivated to become more independent from foreign energy imports. These factors will lead to installation of large numbers of distributed renewable energy generators, which are often intermittent in nature. This trend conflicts with the current power grid control infrastructure and strategies, where a few centralized control centers manage a limited number of large power plants such that their output meets the energy demands in real time. As the proportion of distributed and intermittent generation capacity increases, this task becomes much harder, especially as the local and regional distribution grids where renewable energy generators are usually installed are currently virtually unmanaged, lack real time metering and are not built to cope with power flow inversions (yet). All this is about to change, and so the control strategies must be adapted accordingly. While the hierarchical command-and-control approach served well in a world with a few large scale generation facilities and many small consumers, a more flexible, decentralized, and self-organizing control infrastructure will have to be developed that can be actively managed to balance both the large grid as a whole, as well as the many lower voltage sub-grids. We propose a competitive simulation test bed to stimulate research and development of electronic agents that help manage these tasks. Participants in the competition will develop intelligent agents that are responsible to level energy supply from generators with energy demand from consumers. The competition is designed to closely model reality by bootstrapping the simulation environment with real historic load, generation, and weather data. The simulation environment will provide a low-risk platform that combines simulated markets and real-world data to develop solutions that can be applied to help building the self-organizing intelligent energy grid of the future. Block, C.A. Collins, J. Ketter, W. Weinhardt, C. http://repub.eur.nl/res/pub/17310/ 2009-11-24T00:00:00Z The significant impact of international tourism in stimulating economic growth is especially important from a policy perspective. For this reason, the relationship between international tourism and economic growth would seem to be an interesting empirical issue. In particular, if there is a causal link between international tourism demand and economic growth, then appropriate policy implications may be developed. The purpose of this paper is to investigate whether tourism specialization is important for economic development in East Asia and the Pacific, Europe and Central Asia, Latin America and the Caribbean, the Middle East and North Africa, North America, South Asia, and Sub-Saharan Africa, over the period 1991-2008. The impact of the degree of tourism specialization, which is incorporated as a threshold variable, on economic growth is examined for a wide range of countries at different stages of economic development. The empirical results from threshold estimation identify two endogenous cut-off points, namely 14.97% and 17.50%. This indicates that the entire sample should be divided into three regimes. The results from panel threshold regression show that there exists a positive and significant relationship between economic growth and tourism in two regimes, the regime with the degree of tourism specialization lower than 14.97% (regime 1) and the regime with the degree of tourism specialization between 14.97% and 17.50% (regime 2). However, the magnitudes of the impact of tourism on economic growth in those two regimes are not the same, with the higher impact being found in regime 2. An insignificant relationship between economic growth and tourism is found in regime 3, in which the degree of tourism specialization is greater than 17.50%. The empirical results suggest that tourism growth does not always lead to economic growth. Chang, C.L. Khamkaew, T. McAleer, M.J. http://repub.eur.nl/res/pub/17492/ 2009-11-10T00:00:00Z This paper studies asymmetric price responses of individual firms, via daily retail prices of almost all gasoline stations in the Netherlands and suggested prices of the five largest oil companies over more than two years. I find that 38% of the stations respond asymmetrically to changes in the spot market price. Hence, asymmetric pricing is not a feature of the market as a whole, but of individual firms. For asymmetrically pricing stations, the asymmetry is substantial directly after a change but disappears after one or two days. I study station-specific characteristics and conclude that asymmetric pricing seems to be a phenomenon that is randomly distributed across stations. I also find that none of the five largest oil companies adjust their suggested prices asymmetrically. Faber, R.P. http://repub.eur.nl/res/pub/15412/ 2009-04-07T00:00:00Z We address the value of RFID technology enabled information to manage perishables in the context of a supplier that sells a random lifetime product subject to stochastic demand and lost sales. The product's lifetime is largely determined by the time and temperature history in the supply chain. We compare two information cases to a Base case in which the product's time and temperature history is unknown and therefore its shelf life is uncertain. In the first information case, the time and temperature history is known and therefore the remaining shelf life is also known at the time of receipt. The second information case builds on the first case such that the supplier now has visibility up the supply chain to know the remaining shelf life of inventory available for replenishment. We formulate these three different cases as Markov decision processes, introduce well performing heuristics of more practical relevance, and evaluate the value of information through an extensive simulation using representative, real world supply chain parameters. Ketzenberg, M.E. Bloemhof-Ruwaard, J.M. http://repub.eur.nl/res/pub/15142/ 2009-03-08T00:00:00Z Traditionally, recommender systems present recommendations in lists to the user. In content- and knowledge-based recommendation systems these list are often sorted on some notion of similarity with a query, ideal product specification, or sample product. However, a lot of information is lost in this way, since two even similar products can differ from the query on a completely different set of product characteristics. When using a two dimensional, that is, a map-based, representation of the recommendations, it is possible to retain this information. In the map we can then position recommendations that are similar to each other in the same area of the map. Both in science and industry an increasing number of two dimensional graphical interfaces have been introduced over the last years. However, some of them lack a sound scientific foundation, while other approaches are not applicable in a recommendation setting. In our chapter, we will describe a framework, which has a solid scientific foundation (using state-of-the-art statistical models) and is specifically designed to work with e-commerce product catalogs. Basis of the framework is the Product Catalog Map interface based on multidimensional scaling. Also, we show another type of interface based on nonlinear principal components analysis, which provides an easy way in constraining the space based on specific characteristic values. Then, we discuss some advanced issues. Firstly, we discuss how the product catalog interface can be adapted to better fit the users' notion of importance of attributes using click stream analysis. Secondly, we show an user interface that combines recommendation by proposing with the map based approach. Finally, we show how these methods can be applied to a real e-commerce product catalog of MP3-players. Kagie, M. Wezel, M.C. van Groenen, P.J.F. http://repub.eur.nl/res/pub/15029/ 2009-03-02T00:00:00Z This paper discusses how a manufacturer and its retailers interact with each other to optimize their product marketing strategies, platform product configuration and inventory policies in a VMI (Vendor Managed Inventory) supply chain. The manufacturer procures raw materials from multiple suppliers to produce a family of products sold to multiple retailers. Multiple types of products are substitutable each other to end customers. The manufacturer makes its decision on raw materials’ procurement, platform product configuration, product replenishment policies to retailers with VMI, price discount rate, and advertising investment to maximize its profit. Retailers in turn consider the optimal local advertising and retail price to maximize their profits. This problem is modeled as a dual simultaneous non-cooperative game (as a Nash game) model with two sub-games. One is between the retailers serving in competing retail markets and the other is between the manufacturer and the retailers. This paper combines analytical, iterative and GA (genetic algorithm) methods to develop a game solution algorithm to find the Nash equilibrium. A numerical example is conducted to test the proposed model and algorithm, and gain managerial implications. Yu, Y. Huang, G.Q. http://repub.eur.nl/res/pub/14615/ 2009-01-30T00:00:00Z A warehouse needs to have sufficient open locations to be able to store incoming shipments of various sizes. In combination with ongoing load retrievals open locations gradually spread over the storage area. Unfavorable positions of open locations negatively impact the average load retrieval times. This paper presents a new method to manage these open locations such that the average system travel time for processing a block of storage and retrieval jobs in an automated warehousing system is minimized. We introduce the effective storage area (ESA), a well-defined part of the locations closest to the depot; where only a part of the open locations –the effective open locations-, together with all the products, are stored. We determine the optimal number of effective open locations and the ESA boundary minimizing the average travel time. Using the ESA policy, the travel time of a pair of storage and retrieval jobs can be reduced by more than 10% on average. Its performance depends hardly on the number or the sequence of retrievals. In fact, in case of only one retrieval, applying the policy leads already to beneficial results. Application is also easy; the ESA size can be changed dynamically during storage and retrieval operations. Yu, Y. Koster, M.B.M. de http://repub.eur.nl/res/pub/14529/ 2009-01-13T00:00:00Z Many of the challenges in spare parts logistics emerge due to the combination of large service networks, and sporadic/slow-moving demand. Customer heterogeneity and stringent service deadlines entail further challenges. Meanwhile, high revenues rates in service operations motivate companies to invest and optimize the service logistics function. An important aspect of the spare parts logistics function is its ability to support customer-specific requirements with respect to service deadlines. To support customer specific operations, many companies are actively maintaining and utilizing installed base data during forecasting, planning and execution stages. In this paper, we highlight the potential economic value of installed base data for spare parts logistics. We also discuss various data quality issues that are associated with the use of installed base data and show that planning performance depends on the quality dimensions. Jalil, M.N. Zuidwijk, R.A. Fleischmann, M. Nunen, J.A.E.E. van http://repub.eur.nl/res/pub/14001/ 2008-12-15T00:00:00Z Real estate markets around the world have earned a complicated reputation. On the one hand, real estate markets offer investors a wide spectrum of profitable investments opportunities, investments that nowadays can be executed by simply buying shares of stock listed by real estate investment companies. In the first half of this inaugural address, the boom of these real estate stocks is discussed. In less than three decades, the listed real estate market developed into a sector with almost 400 listed firms worldwide, representing a sum aggregate market capitalization of around one trillion dollars by the end of 2007. Three relevant lessons regarding these international real estate stocks are discussed in the first fifteen pages of this booklet, lessons offered by real estate research from the Rotterdam School of Management. On the other hand, real estate markets are notorious for attracting entrepreneurs with bad intentions, seeking for opportunities to circumvent the strong arm of the law. These activities have yielded many headlines in the daily press and have given real estate a gloomy reputation. The dynamics of foreclosure auction of homes is an example of a source of negative headlines, stressing that the suboptimal organization of these auctions prohibits distressed sellers from earning a fair price for their home. In the second part of this address, I focus on an empirical test of the matter. By analyzing over 700 auctioned homes the dynamics of the auction system is discussed objectively. This offers a fair view on the problems at hand and searches for way to improve the system in the near future. Brounen, D. http://repub.eur.nl/res/pub/13615/ 2008-10-24T00:00:00Z This study contributes to the retail adoption literature by explicitly focusing on the role of both profit-related and relationship variables in explaining new product adoption decisions by retailers, instead of considering either one of these groups of variables in isolation as has been done by previous retail adoption studies. Moreover, it specifically addresses how both relationship quality and a retailer’s dependence on the manufacturer moderate the effect of profit drivers. Using a sample of 392 new product adoption decisions by four Dutch retailers, the authors estimate a random effects logit model to explain adoption decisions. The results show significant positive main effects of gross margin, consumer support, product uniqueness, relationship quality and the retailer’s dependency on the manufacturer on the adoption decision. Moreover, the authors find that improved relationship quality tends to reduce the importance of both gross margin and consumer support in the adoption decision process, but surprisingly leads to a stronger impact of trade support. The moderating effect of the retailer’s dependence on the manufacturer also differs between profit drivers, such that it decreases the positive impact of gross margin, consumer support and product uniqueness, and it increases the negative effect of store brand cannibalization. Everdingen, Y.M. van Sloot, L.M. Verhoef, P.C. http://repub.eur.nl/res/pub/13556/ 2008-06-01T00:00:00Z This review addresses supply chain management issues specific to Internet fulfillment in a multi-channel environment. It provides a systematic overview of managerial planning tasks and corresponding quantitative models. Our objective is to twofold, namely to enhance the understanding of multi-channel e-fulfillment by documenting the current state of affairs, and to inspire fruitful future research by identifying gaps between relevant managerial issues and available academic literature. One of the recurrent patterns in today’s e-commerce operations is the combination of ‘bricks-and-clicks’ – the integration of e-fulfillment into a portfolio of multiple alternative distribution channels. From a supply chain management perspective, multi-channel distribution provides opportunities for serving different customer segments, creating synergies, and exploiting economies of scale. However, in order to successfully exploit these opportunities companies must master novel challenges. In particular, the design of a multi-channel distribution system requires a constant trade-off between process integration and separation across multiple channels. In addition, sales and operation decisions are ever more tightly intertwined as delivery and after-sales services are becoming key components of the product offering. Agatz, N.A.H. Fleischmann, M.
