Combining filter design with model-based filtering (with an application to business-cycle estimation)

Filters used to estimate unobserved components in time series are often designed on a priori grounds, so as to capture the frequencies associated with the component. A limitation of these filters is that they may yield spurious results. The danger can be avoided if the so-called ARIMA-model-based (AMB) procedure is used to derive the filter. However, parsimony of ARIMA models typically implies little resolution in terms of the detection of hidden components. It would be desirable to combine a higher resolution with consistency of the structure of the observed series.We show first that for a large class of a priori designed filters, an AMB interpretation is always possible. Using this result, proper convolution of AMB filters can produce richer decompositions of the series that incorporate a priori desired features of the components and fully respect the ARIMA model for the observed series (hence no additional parameter needs to be estimated).The procedure is discussed in detail in the context of business-cycle estimation by means of the Hodrick-Prescott filter applied to a seasonally adjusted series or a trend–cycle component.     

Partial Adjustment or Stale Prices? Implications from Stock Index and Futures Return Autocorrelations

We investigate the relation between returns on stock indicesand their corresponding futures contracts to evaluate potentialexplanations for the pervasive yet anomalous evidence of positive,short-horizon portfolio autocorrelations. Using a simple theoreticalframework, we generate empirical implications for both microstructureand partial adjustment models. The major findings are (i) returnautocorrelations of indices are generally positive even thoughfutures contracts have autocorrelations close to zero, and (ii)these autocorrelation differences are maintained under conditionsfavorable for spot-futures arbitrage and are most prevalentduring low-volume periods. These results point toward microstructure-basedexplanations and away from explanations based on behavioralmodels.     

When the going gets tough,ads become straightforward but multi-appealed: The influence of the recession on financial services advertising appeals

Although many scholars and researchers have contributed to the sizeable literature on the relationship between advertising and society, few have examined economic circumstances as a meaningful force shaping advertising. This study provides the empirical evidence that changes in economic conditions, the recession in particular, can transform advertising appeals. The analysis of 1488 financial services ads placed in two popular US magazines showed that the patterns of appeals have turned to direct assertive styles in the wake of the economic crisis of the period 2008–2009. At the same time, however, ads during this recession period have used a far wider variety of strategic and tactical appeals than those in pre-recession era.     

Resource-based and institution-based approaches to biotechnology industry development in Malaysia

In this study, we use both resource-based and institution-based theories to examine potential sources of competitive advantage in the relatively new and rapidly growing biotechnology sector. We then use those theories as the basis for a multimethod study to assess the priorities, capabilities, and competitiveness of the emerging biotechnology industry in Malaysia. Multifunctional experts from a biotechnology industry organization in Malaysia identified the use of biotechnology for agriculture and biofuels as key country priorities, with access to funding and talent cited as key capabilities required for successful sector development. The gap between capabilities required and strategic priorities provides a “to do” list for industry development, with government institutions playing a central role in accelerating technology development and providing the capital flows necessary to bridge this gap. Implications include the need for public–private sector collaboration to enable biotech firms to efficiently obtain international investment and alliances to ensure sustainability, as well as to develop bold and creative approaches for developing and recruiting talent both at home and abroad.     

Examining the Factors Affecting Perceived Enjoyment and Usage Intention of Ubiquitous Tour Information Services: A Service Quality Perspective

With the advances in mobile technologies, the ubiquitous tour information service has been emerging as a new solution for providing tour information. This study examined the effects of ubiquitous tour information service on perceived enjoyment and usage intention by tourists. The study begins with a preliminary survey of mobile device users’ motives and perceptions of usage, followed by a review of the related literature. The measurements were derived from this process. The demonstrative analysis results classify the quality of ubiquitous tour information service into four categories: system quality, information quality, interface design, and convenience. Before analyzing the data, an exploratory factor analysis for reliability and validity assessment was conducted. Whereas the factors of interface design and convenience did not have a significant impact, the remaining two factors, system quality and information quality, impacted users’ perceived enjoyment to a much greater extent. The four categories of ubiquitous tour information service were shown to affect usage intention. Of the four factors, system quality was found to have the highest impact on usage intention, followed by convenience, interface design, and information quality, in that order. The association between perceived enjoyment and usage intention was also supported. Based on the results, academic and managerial implications are discussed.     

New Product Development Process Implementation in a Business-To-Business Firm: The Driving and Moderating Factors for Improved Program Performance and Time-To-Market

Purpose: The study aims to examine the critical factors affecting the implementation of a formalized new product development (NPD) process in a business-to-business (B-to-B) company with product-driven growth.

Methodology/approach: Case study using a combination of survey, artifacts, and long interviews

Findings: The findings suggest that (1) the initial phase proficiency can improve NPD effectiveness (NPD program performance) and NPD efficiency (i.e., time-to-market), but this relationship is moderated by the effective communication of the new NPD process throughout the entire firm; (2) the process formalization enhances time-to-market and NPD program performance, but its effects are asymmetric and contingent upon the decision concerning the inclusion of ad hoc and extended NPD team members; and (3) the product approval (executive) committee’s (PAC) ineffective communication could alienate team members from NPD efforts while resource availability moderates the influence of PAC’s decision making quality on time-to-market.

Research implications: Future research could examine the PAC decision-making quality as a multidimensional construct, composed of rigor and timeliness dimensions. That way, a more granular understanding of the effect of PAC decisions could be achieved. Future studies could make a clear distinction of the NPD process type in the study context when NPD decisions are examined.

Practical implications: Managers should acknowledge that decision-making processes and their comprehension by worker bees affect an NPD program’s success. It is interesting to note that removing go-no go decisions by the product approval committees at each phase may not lead to faster product development as these executive committee meetings have double entendre: they are not only to get the executives informed and get their signoff, but also is a facilitator to capital approvals. Hence, appropriate measures must be taken to remove or ease all bottlenecks in the NPD process.

Originality/value/contribution: This study uncovers several crucial factors that can improve the effectiveness and time-to-market of an NPD program in B-to-B companies, especially when firms implement a new formalized NPD process.     

Spillover, Competition and Better R&D Organization

This paper examines several types of R&D organization, including one noncooperative (independent R&D) form and three cooperative ones (R&D coordination, an R&D consortium and a research joint venture (RJV)). We consider the sharing of both research inputs and outputs in an R&D consortium and an RJV. We show that the superiority of a form of R&D organization cannot be determined uniquely, but should be judged by four parameters. In addition, it is shown that there exist possible mixes of these parameters in which an R&D consortium is superior to either R&D coordination or an RJV in terms of technological improvement and social welfare.

A New Control Variate Estimator for an Asian Option

There exist several estimators for valuing the Asian option on the arithmetic mean. Among all variance reduction estimators, the one with the control variate derived from the geometric mean has been shown by Boyle et al. (1997) to perform best so far. In this paper, a new improved control variate estimator for this type of Asian option is proposed and investigated. Simulation results confirm that it does perform better than the control variate derived from the geometric mean. The improvement becomes more significant as the volatility increases and/or as the time to expiration lengthens.
