Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

行銷硏究 : Marketing research

Understanding customer experience and the customer journey over time is critical for firms. Customers now interact with firms through myriad touch points in multiple channels and media, and customer experiences are more social in nature. These changes require firms to integrate multiple business functions, and even external partners, in creating and delivering positive customer experiences. In this article, the authors aim to develop a stronger understanding of customer experience and the customer journey in this era of increasingly complex customer behavior. To achieve this goal, they examine existing definitions and conceptualizations of customer experience as a construct and provide a historical perspective of the roots of customer experience within marketing. Next, they attempt to bring together what is currently known about customer experience, customer journeys, and customer experience management. Finally, they identify critical areas for future research on this important topic.

Understanding Customer Experience Throughout the Customer Journey

Grounded in sociological agency theory, the authors study the role of the faculty research
incentive system in the academic research conducted at business schools and business school
health. The authors surveyed 234 marketing professors and completed 22 interviews with 14
(associate) deans and 8 external institution stakeholders. They find that research quantity
contributes to the research health of the school, but not to other aspects of business school health.
r-quality of research (i.e., rigor) contributes more strongly to the research health of the school
than research quantity. q-quality (i.e., practical importance) of research does not contribute to the
research health of the school but contributes positively to teaching health and several other
dimensions of business school health. Faculty research incentives are misaligned: (1) when
monitoring research faculty, the number of publications receives too much weight, while
creativity, literacy, relevance, and awards receive too little weight; and (2) on average, faculty
feels that they are insufficiently compensated for their research, while (associate) deans feel they
are compensated too much for their research. These incentive misalignments are largest in
schools that perform the worst on research (r- and q-) quality. The authors explore how business
schools and faculty can remedy these misalignments.

Faculty Research Incentives and Business School Health: A New Perspective from and for Marketing

Marketing competition in the 21st century

The number of citations a paper receives is the most commonly used measure of scientific impact. In this paper, we study not only the number but also the type of citations that 659 marketing articles generated. We discern five citation types: application, affirmation, negation, review and perfunctory mention (i.e., citing an article only indirectly without really using it). Prior literature in scientometrics recognizes that the former three types, on average, signal a higher level of scientific indebtedness than the latter two types. In our sample, these three types of citation represent only 15% of all citations. We also find different determinants of citation behavior across citation types. Across the 49 determinants we included, only 13 have the same effect across all citation types, of which only 5 are statistically significant across all citation types. For instance, we find a significant inverted U-effect of challenging commonly held beliefs on citations counts, but only for three of the citation types: affirmation, review and perfunctory mention. Our results encourage scientific stakeholders to move beyond mere citation counts to assess a paper’s or a scholar’s scientific contribution, as well as to devote greater attention to the citation process itself.

Faculty Research Incentives and Business School Health: A New Perspective from and for Marketing:

textPrior marketing literature has overlooked the role of regulatory regimes in explaining international sales growth of new products This paper addresses this gap in the context of new pharmaceuticals (15 new molecules in 34 countries) and sheds light on the effect regulatory regimes have on new drug sales across the globe Based on a time-varying coefficient model, we find that differences in regulation substantially contribute to cross-country variation in sales One of the regulatory constraints investigated, ie manufacturer price controls, has a positive effect on drug sales The other forms of regulation such as restrictions of physician prescription budgets and the prohibition of direct-to-consumer advertising tend to hurt sales The effect of manufacturer price controls is similar for newly launched and mature drugs In contrast, regulations on physician prescription budget and direct-to-consumer advertising have a differential effect for newly launched and mature drugs While the former hurts mature drugs more, the latter has a larger effect on newly launched drugs In addition to these regulatory effects, we find that national culture, economic wealth, introduction timing, lagged sales and competition, also affect drug sales Our findings may be used as input by managers for international launch and sales decisions They may also be used by public policy administrators to compare drug sales in their country to other countries and to assess the role of regulatory regimes therein
