Developing a Novel Hybrid Model for Industrial Environment Analysis: A Study of the Gourmet and Tourism Industry in Taiwan

This study applies fuzzy set theory in attempting to evaluate important attributes of the tourism and gourmet business environment in Taiwan. This business environment is composed of various attributes that are difficult to measure. To overcome these challenges, we integrated the fuzzy Delphi method, the decision-making trial and evaluation laboratory method, and the analytic network process to evaluate the business environment. We found that the most significant aspect of the tourism and gourmet business environment is human resources and that the least significant aspect of this industry is market development. The most significant criteria are enhanced industry competitiveness and opportunities to develop the industry.     

“国际金融中心”需要怎样的城市形象广告片?——上海城市形象广告片的受众认知和态度比较研究

上海立志建设成为国际金融中心,打造这一城市品牌形象是一个系统工程,营销传播工作是重要的组成。本研究从广告效果空间论角度,对上海现有的四部城市形象广告进行了受众认知和态度效果的比较,并引入中外受众所代表的不同涉入度作为调节变量。我们根据结果绘制了四支广告在认知-态度二维图上的位置,并发现不同涉入度对认知效果没有调节作用,而对态度效果上则有调节作用。基于这些发现,我们提出了如何创作有效的国际金融中心城市形象广告的建议。     

House prices,collateral constraint,and the asymmetric effect on consumption

This paper investigates the asymmetric effect of house prices on various categories of consumption under constrained and unconstrained regimes. We first present a simple theoretical model based on Iacoviello (2004) and Luengo-Prado (2006), explicitly considering the dual role of housing and linking credit constraints to the behavior of consumption in a pair of aggregate Euler equations. We then estimate a threshold regression model and find that LC-PIH holds only under the unconstrained regime. More importantly, durable consumption exhibit a very strong asymmetric effect in response to changes in house prices, while other categories of consumption do not exhibit this asymmetry.     

Redistribution and growth: Pareto improvements

This paper analyzes the relationship between income distribution and economic growth. It introduces heterogeneous households who have preferences for leisure into Grossman and Helpman's model of endogenous growth (in which income distribution has no effect on economic growth). Wealth distribution affects the endogenous rate of growth as the labor supply of each individual responds inversely to his permanent income. When the labor Engel curve is concave (convex), unequal wealth distribution decreases (increases) the rate of growth. Pareto-improving-growth-enhancing wealth redistributions are characterized.     

Long-term stock performance following extraordinary and special cash dividends

Using essentially all declared extraordinary and special cash dividends between 1926 and 2001 which are not preceded or followed by the same for a period of three years, we find no robust post-declaration long-term abnormal stock returns, even in sub-samples defined by the special dividend yield, the bang-for-the-buck, the declaration-period abnormal return, the sub-sampling period or the stock market condition at declaration. Only event firms in the smallest CRSP market capitalization quintile display significant positive abnormal returns during the first-year following the declaration. However, these latter are not robust across sub-sampling periods. Overall, there is no compelling evidence that investors under- or over-react to extraordinary or special cash dividends.     

Knowledge exchange and knowledge protection in interorganizational learning: The ambidexterity perspective

Are knowledge exchange and knowledge protection conflicting or complementary? Although facilitating knowledge exchange and protecting core proprietary knowledge are important in interorganizational learning, extant studies often regard them as conflicting activities. Few studies have discussed the mechanisms that can help firms achieve both. In this current study, we extend the concept of ambidexterity to the interorganizational learning context and suggest several mechanisms that can enhance knowledge exchange and knowledge protection simultaneously. We conducted a survey and the empirical results reveal that experience sharing and shared interpretation are positively associated with knowledge exchange success. Hostage arrangement enhances the level of knowledge protection, whereas reciprocal investment has no effect on knowledge protection. Furthermore, ambidexterity (the product term of knowledge exchange success and knowledge protection) significantly affects the performance of a firm. Finally, we discuss the implications of this research and offer suggestions for future research.     

The stalemate of cable digital switchover: A study of competition effects and deregulation

This paper addresses the phenomenon of delayed cable digitization in Taiwan and reports the results of a longitudinal analysis, determining that (1) inter-platform competition, primarily from internet protocol television (IPTV), generates a strong and positive impact on the digitization of cable service after it acquires numerous customers; (2) the installed cable base induces economies of scale that increase its digital penetration; (3) the overbuild of the equivalent-size rivalry can increase digital adoption, whereas unequal-sized competition might reversely decrease it; and (4) the monthly flat fee charged to customers does not influence digital adoption. In addition, this paper presents a discussion on the policy instruments derived from econometric results. Although repealing the horizontal integration cap in the cable TV industry could generate economies of scale, doing so may encourage monopolization over several franchises. The efficacy of intra-platform competition is reserved only for certain cases. Combining the results of these analyses reveals that inter-platform competition most effectively stimulates cable operators’ digital conversion. Hence, regulators should create a level playing field among various TV platforms, such as equal programming access and open standards, to ensure a high degree of cable digitization     

An evaluation of influenza preventive measures on airlines: A passenger’s perspective

This paper examines influenza preventive measures on airlines based on a questionnaire survey of passengers at Taipei’s Taoyuan international airport. Quadrant scatter-plots of influenza preventive service attributes revealed that the clean cabin and disinfection services fell into the “Keep up the Good Work” quadrant; the personal protective requirements dimension in the “Low Priority” quadrant, and influenza preventive equipment dimension fell in the “Possible Overkill quadrant.”     

An empirical study of the impact of information technology intensity in strategic investment decisions

This paper focuses on two issues of the management of strategic information technology investment decisions (SITIDs). First, it examines the outcomes of strategic investment decisions (SIDs) according to the extent of IT intensity in the investment project (termed IT-ness). Second, IT-ness is assessed in realtion to a numberr of dimensions, including decision formulating process, evealuation process and decision content. Empirical testing is based on a sample of 80 SIDs from Taiwanese enterprises. Thw results show that IT-ness is negatively associated with the effectiveness of SIDs and several constructs in the decision process. The implicaitons of this for the evaluaiton and management of SITIDs, and on agenda for further research into the effectiveness of SITIDs, are discussed.     

Particle swarm optimization with cocktail decoding method for hybrid flow shop scheduling problems with multiprocessor tasks

This paper addresses the problem of multiprocessor task-scheduling in a hybrid flow shop (HFS) problem to minimize the makespan. Due to the complex nature of an HFS problem, it is decomposed into the following two sequential decision problems: determining the job permutation in stage 1, followed by a decoding method to assign jobs into each machine in subsequent stages when designing a heuristic algorithm. The decoding method plays a pivotal role for improving the solution quality of any algorithm for the HFS problem. However, the majority of existing algorithms ignores the problem and is only concerned with the first decision problem. This study emphasizes the importance of the decoding method via a small test, and searches for a number of solid decoding methods that can be incorporated into the cocktail decoding method. Then, this study develops a particle swarm optimization (PSO) algorithm that can be combined with the cocktail decoding method. In the PSO, a variety of job sequences are generated using the PSO procedure in stage 1, and the cocktail decoding method is used to assign the jobs to machines in sequential stages. Moreover, a modified lower bound is introduced. Computational results show that the proposed lower bound is competitive, and with the help of the cocktail decoding method, the proposed PSO, and even the adoption of a standard PSO framework, significantly outperforms the majority of existing algorithms in terms of quality of solutions, especially for large problems.
