Incorporating choice dynamics in models of consumer behavior

This paper presents a framework for organizing and discussing factors influencing consumer choice dynamics, how these factors may be incorporated into models of buyer behavior and problems that may arise in estimating such models. The paper identifies research issues and delineates possible approaches. Proceedings of Session on Choice Dynamics at the Banff Symposium on Consumer Decision-Making and Choice Behavior.

Cost per additional responder for ixekizumab and other FDA-approved biologics in moderate-to-severe plaque psoriasis

Background: Evidence of the cost-efficacy of ixekizumab for the treatment of moderate-to-severe plaque psoriasis (PsO) in the US is limited.

Objective: To estimate the number needed to treat (NNT) and monthly cost of achieving one additional Psoriasis Area and Severity Index (PASI) 75, 90, and 100 responder for ixekizumab and other Food and Drug Administration (FDA)-approved biologics in PsO.

Methods: A network meta-analysis estimated the probability of achieving PASI 75, 90, or 100 response during induction for each biologic. NNTs were calculated using response difference of each respective biologic vs placebo at the end of induction. Monthly costs per additional PASI responder were based on FDA-approved doses, wholesale acquisition costs, and induction NNTs.

Results: Induction NNTs for ixekizumab 80?mg once every 2 weeks (Q2W) relative to placebo were consistently lower across all levels of clearance compared with the other biologics. Monthly cost per additional responder was lowest for ustekinumab 45?mg at PASI 75 and for secukinumab 300?mg and ixekizumab 80?mg Q2W at PASI 90. Ixekizumab 80?mg Q2W had the lowest cost for PASI 100.

Conclusion: In this analysis, ixekizumab is the most cost-efficient biologic in the US when targeting complete resolution, as measured by PASI 100 in PsO.     

Interactive effects of marketing strategy formulation and implementation upon firm performance

Abstract

This study employed an integrative approach to investigate the influence of external business environment, strategy formulation, viability of marketing strategy, and strategy implementation upon firm performance. The findings show that while technological change and market competition negatively influence the credibility of the strategy, market attractiveness has a positive influence upon the viability of strategy employed. Moreover, market competition has a positive influence upon the involvement of marketing managers in terms of strategy making and that the presence of an innovative culture is strongly required in executing a strategic marketing plan. In addition, the study shows that the involvement of marketing managers in strategy making, which is strongly supported by an innovative culture, generates their commitment to the strategy, which positively influences strategy viability.     

Dynamic interaction networks in modelling and predicting the behaviour of multiple interactive stock markets

The behaviour of multiple stock markets can be described within the framework of complex dynamic systems. A representative technique of the framework is the dynamic interaction network (DIN), recently developed in the bioinformatics domain. DINs are capable of modelling dynamic interactions between genes and predicting their future expressions. In this paper, we adopt a DIN approach to extract and model interactions between stock markets. The network is further able to learn online and updates incrementally with the unfolding of the stock market time-series. The approach is applied to a case study involving 10 market indexes in the Asia Pacific region. The results show that the DIN model reveals important and complex dynamic relationships between stock markets, demonstrating the ability of complex dynamic systems approaches to go beyond the scope of traditional statistical methods.

Sterilization and the monetary approach to balance of payments analysis

The authorities can sterilize the balance of payments in both the short and long run if domestic capital markets are not fully integrated with those of the rest of the world. The degree of sterilization which the authorities employ is an important determinant of the economy's response to any outside changes.     

Framing the constructive alignment of design within technology subjects in general education

Design is core element of general technology education internationally. While there is a degree of contention with regards to its treatment, there is general consensus that the inclusion of design in some form is important, if not characteristic, of the subject area. Acknowledging that design is important, there are many questions which need to be considered in order to guide policy and practice, such as whether a singular general design ability can be explicitly defined empirically beyond an implicit verbal definition, and whether it can be taught and assessed. In order to address these questions in a systematic fashion, a framework is needed in order to guide relevant investigations. Having such a framework would allow for theory to be generated, hypotheses to be tested, and assumptions to be challenged. In response to this apparent need, this article presents a theoretical discussion pertaining to the constructive alignment of learning to design, wherein theories of knowledge, variation theory, knowledge transfer, and assessment validity and reliability are reflected upon.

     

Productivity,Scale and Efficiency in the U.S. Textile Industry

In this paper we employ panel data techniques to address several issues related to the recent performance of the textile industry. We build on the research and results obtained by Ramcharran (in Empirical Econ 26:515–524, 2001) for the textile industry as a whole, by extending the analysis to the sector level. Using data for 23 sectors over 39 years (1958–1996), we estimate a variable elasticity of substitution (VES) production function; the results allow us to construct time-series of marginal products of inputs and elasticities of scale and substitution. We find evidence in support of the use of a VES function and conclude that there are systematic differences among textile sectors’ productivity and performance.     

The impact of psychological contracts upon trust and commitment within supplier-buyer relationships: A social exchange view

Central to this study is the emerging body of knowledge describing how social exchange relationships are being nurtured. A random sample of 343 Australian distributor firms from within the motorized vehicle industry was used to test a model developed on the basis of social exchange theory. Psychological contracts are perceptual in nature and were found to encompass reciprocal obligations stemming directly from the relational orientation between suppliers and distributors. This construct was also shown to have a positive impact upon the level of trust and commitment within the relationship. These findings have significant managerial implications for the manner in which managerial decision makers are modelling the firm-customer relationship because trust and commitment are essential elements in the development and maintenance of such relationships. The theoretical and managerial implications discussed have highlighted the need for further studies because there are deficiencies in the marketing literature pertaining to this important construct.
